1 Introduction 

This report presents the results of our geotechnical engineering study and provides recommendations for 

the design and construction of buildings and structure within the platform area of the West Rail Yard of 

Hudson Yards. All services were performed in general accordance with our proposal of 27 January 2017. 

Environmental conditions at the site will be discussed under separate cover. 

Our understanding of the project is based on our review of the project documents, discussions with the 

design team, and our experience throughout Hudson Yards and the surrounding area. Architectural 

information was provided by the project architect (Kohn Pederson Fox Associates, PC – KPF), and 

structural information was provided by the project structural engineer (Mueser Rutledge Consulting 

Engineers – MRCE). 

All elevations are referenced to the North American Vertical Datum of 1988 (NAVD88). Typical datum 

conversions are presented in Table 1. Note: The historical drawings and data referenced in this report 

utilize multiple datum planes; caution should be exercised in comparing this information. 

Table 1: Typical Elevation Conversions from NAVD88 

Datum Conversion

National Geodetic Vertical Datum of 1929 (NGVD29) NAVD88 + 1.076 ft

Borough President of Manhattan Datum (BPMD) NAVD88 - 1.676 ft

New York City Transit Datum (NYCT) NAVD88 + 98.423 ft

2 Site Description 

The project is on the Far West Side of Manhattan within the western half of the Metropolitan 

Transportation Authority (MTA) – Long Island Rail Road (LIRR) West Side Yards. The West Rail Yard 

(WRY) site is divided into “platform” (Block 676, Lot 5) and “terra firma” (Block 676, Lot 1) parcels. This 

report focuses solely on the platform site. The platform site measures about 423,000 square feet and is 

bound by West 33rd Street on the north, the terra firma parcel on the south, the Eleventh Avenue viaduct 

on the east, and Twelfth Avenue (New York State Rout 9A/Westside Highway) on the west. The site 

location is shown in Figure 1.

The majority of the platform site is occupied by 30 east-west oriented railroad tracks that are separated by 

concrete walkways of varying width. An access road runs along the west and south site perimeters. 

Numerous structures are located within and adjacent to the site as discussed herein. 

Surface grades within the site are relatively flat, from about el 7 ft to el 10 ft. However, grades on the 

streets fronting the site vary considerably and generally slope down to the west and south. The highest 

elevation is on the Eleventh Avenue viaduct east of the site. Eleventh Avenue crowns at about el 34 ft in 

the vicinity of the former West 32nd Street right of way; the street slopes down to about el 33 ft at the 

intersection with West 33rd Street at the north and down to about el 18 ft at the intersection with West 30th

Street at the south. West 33rd Street slopes down from a high point of about el 33 ft at the intersection 

with Eleventh Avenue on the east to about el 6.0 ft at the intersection with Twelfth Avenue on the west. 

Twelfth Avenue is relatively flat varying from about el 5.5 ft to el 6.5 ft in the area of the site. 

3 EXISTING STRUCTURES AND UTILITIES 

The following sections briefly describe existing structures in the area of the platform site. The 

approximate locations of the existing structures are shown in Figure 2. 
HUDSON YARDS 

HYW-PL-LAN-RPT-A-20170501 GEOTECHNICAL REPORT P A G E | 2

MAY 1, 2017

3.1 WRY Track Support 

The tracks within the WRY are either: 1) directly fixed to reinforced concrete slabs (Tracks 4 through 30) 

or 2) spiked to wooden ties supported by ballast (Tracks 1 through 3). Ballasted track sections are 

comprised of an approximately 10-inch thick reinforced concrete subslab cast atop the soil subgrade, with 

stone ballast placed atop the subslab. Reinforced concrete slab sections are comprised of about 

22 inches of subbase fill placed atop the soil subgrade that are capped by about 4 inches pf bituminous 

stabilized course and the reinforced concrete track slab that is about 13- to 14-inches thick. 

3.2 LIRR Support Structures 

There are three 2-story masonry buildings on the west side of the site, at the end of the tracks. These 

buildings serve as administrative and maintenance facilities for the rail yard and are referred to as the 

“Yard Operations”, “Extraordinary Interior Cleaning (EIC) Storage” and “Transportation” buildings. These 

buildings are supported on spread footings bearing in soil, and will be demolished and reconstructed as 

part of the platform project. 

3.3 Extraordinary Interior Cleaning (EIC) Platform 

An 8.5-foot wide raised platform, referred to as the EIC platform, is present between tracks 27 and 28 and 

connects to the EIC building. The EIC platform is used to access trains for cleaning and maintenance 

and is covered by a canopy. The platform is supported on spread footings bearing in soil. The top of the 

platform varies from about el 12 ft to el 14.5 ft; the top of the canopy varies from about el 25 ft to 

el 26.5 ft. 

3.4 Highline (City of New York) 

The Highline Park elevated rail line is on the west end of the platform site parallel to Twelfth Avenue. The 

Highline is a steel-frame structure that served as a freight rail line and was recently converted into a 

public park. The structure is generally supported by timber piles with reinforced concrete pile caps in the 

vicinity of the platform; concrete piers bearing on rock support the structure adjacent to the Amtrak North 

River Tunnels. The top of the foundations are at about el 3.5 ft to el 5 ft. 

The Highline is about 20 feet above grade on the west end of the platform site and will be incorporated 

into the proposed redevelopment. The Highline is to remain and be protected during construction. 

Design and construction near the Highline will be subject to review by the New York State Historic 

Preservation Office (SHPO) and NYC Parks/Friends of the Highline. 

3.5 West 33rd Street Retaining Wall and Viaduct 

The West 33rd Street right of way boarders the north property line of the platform site. The street 

transitions from an on-grade roadway about 64 feet east of Twelfth Avenue and is then supported by a 

stone masonry retaining wall that extends about 465 feet east. The roadway then transitions into a 

viaduct that connects to the Eleventh Avenue viaduct. The westernmost 50 feet of the retaining wall is

supported by a concrete strip footing; the remainder of the retaining wall is supported by timber piles with 

concrete pile caps. A concrete abutment wall is present at the east end of the retaining wall and supports 

steel framing for the viaduct portion of the roadway. Surface grades atop the retaining wall vary from 

about el 8.4 ft to el 24.6 ft. An approximately 8-foot tall concrete parapet (security wall) is located atop 

the retaining wall. The security wall continues west of the retaining wall to the Twelfth Avenue property 

line. 

The eastern portion of West 33rd Street is anticipated to be reconstructed to accommodate grade changes 

necessary for entry into the site. Generally, the West 33rd Street retaining walls are anticipated to remain 

and be protected during construction.

3.6 Eleventh Avenue Viaduct 

The Eleventh Avenue viaduct borders the east side of the WRY. The viaduct generally consists of a 

steel-frame structure with a reinforced concrete deck with an earthen fill abutment at the south end. The 

viaduct was reconstructed during development of the West Side Yards in the 1980s. The south abutment 

was repaired; however, the foundation support of the abutment is unknown. Foundations supporting the 

viaduct within the yards include: 

 Southern piers (Piers 1 through 3) are supported by steel pipe piles extending to bedrock with a 

concrete pile cap. The drawings show both vertical piles and piles battered to the north and 

south. 

 Central piers (Piers 4 and 5) are adjacent to the North River Tunnels. These piers are supported 

by concrete caissons cored into bedrock to about el -43.5 ft (the approximate invert of the Amtrak 

North River tunnels). 

 Northern piers (Piers 6 and 7) are supported by footings bearing on rock. 

The viaduct will remain and must be protected during construction. 

3.7 Twelfth Avenue 

Twelfth Avenue (New York State Route 9A/Westside Highway) borders the site on the west at elevations 

similar to the rail yard. In the vicinity of the site, Twelfth Avenue is an eight-lane, divided highway. A 

concrete security wall runs the length of the site perimeter along Twelfth Avenue. 

3.8 Amtrak North River Tunnels 

The Amtrak North River Tunnels (NRTs) run east-west below the WRY, roughly coincident with the former 

West 32nd Street right of way. The tunnels were constructed by the Pennsylvania Railroad in the early 

1900s to provide rail access to Manhattan via Penn Station. 

West of Eleventh Avenue, the tunnels are comprised of 23-foot diameter segmental cast iron liners with 

an interior concrete lining. The tunnel inverts vary from about el -46.2 ft at the property boundary on 

Eleventh Avenue to about el -61.6 ft at the property boundary on Twelfth Avenue. The corresponding 

tunnel crown elevations vary from about el -23.2 ft to el -38.6 ft, respectively. The NRTs are fully in rock 

to about 360 feet west of Eleventh Avenue and transition to fully soil supported at a distance of about 

500 feet west of Eleventh Avenue. The approximate extents of the NRTs are shown in Figure 2.

The NRTs will remain and must be protected during construction. Construction within 200 feet of the 

NRTs requires Amtrak’s approval to obtain NYC DOB permits. 

3.9 Amtrak North Access Tunnel (Empire Line) 

The Amtrak North Access Tunnel (NAT), also known as the “Empire Line,” passes beneath the northeast 

corner of the site near the intersection of West 33rd Street and Eleventh Avenue. The tunnel was 

constructed in the 1980s by Amtrak to provide rail access through the Westside of Manhattan to points 

north. The tunnel runs west-northwest below the ERY before heading north in a sweeping arc below the 

Eleventh Avenue viaduct, and continues to the northeast beneath the Jacob Javits Truck Marshaling 

Yard. The NAT is just below the railyard surface and crosses above the North River tunnels at about 

Eleventh Avenue. The tunnel invert is at about el -14.3 ft within the site and the crown is located at about 

el 7.2 ft (about 3 foot below existing surface grade). 

The tunnel is a rectangular-shaped, reinforced-concrete structure built using cut and cover construction. 

The tunnel is partially embedded in soil and partially embedded in bedrock. The tunnel is relatively 

shallow, with the deepest point located beneath the ERY; ground cover decreases to the north and the 

tunnel daylights into a U-shaped, reinforced concrete portal north of West 34th Street. A vent/emergency

MAY 1, 2017

egress enclosure for the tunnel is beneath the West 33rd Street viaduct (under West 33rd Street, just west 

of Eleventh Avenue). The approximate locations of the tunnel and vent building are shown in Figure 2. 

The NAT will remain and be must protected during construction. Construction within 200 feet of the NAT 

requires Amtrak’s approval to obtain NYC DOB permits. 

3.10 MTA No. 7 Line Extension 

The MTA No. 7 Line Extension runs beneath Eleventh Avenue adjacent to the site. The No. 7 Line 

includes a station cavern (34th Street Station cavern), a ventilation tunnel (T1A), an interlocking tunnel 

section (south interlocking), and two running tunnels (CC1 and CC2) in the area of the site. The tunnels 

slope up from south to north at an inclination of about 0.5 percent. The 34th Street station cavern runs 

from about 70 feet south of West 33rd Street to about West 36th Street; the invert of the cavern is at about 

el -104.3 feet and the crown of the cavern is at about el -51 ft (about 58 feet below surface) adjacent to 

the site. The T1A ventilation tunnel is located off the east side of the station cavern’s south end, turns 

north and connects to the Site J vent building north of West 33rd Street. The south interlocking section 

extends about 150 feet south of the 34th Street station cavern with an invert of about el -105.1 ft and the 

crown at about el -73.4 ft. The No. 7 Line transitions into two running tunnels about 220 feet south of 

West 33rd Street; inverts elevations adjacent to the site vary from about el -104.8 ft to el -106.4 ft and 

crown elevations vary from about el -82.5 ft to el -84.1 ft. The No. 7 Line is located about 16 to 17 feet 

east of the east property boundary of the WRY. 

The station cavern and interlocking sections were excavated by a combination of tunnel boring machine 

(TBM) bores and controlled blasting. The running tunnels were bored by TBM and the T1A was 

excavated using controlled blasting. 

The MTA No. 7 Line will remain and be must protected during construction. Construction within 200 feet 

of the No. 7 Line requires MTA Capital Construction/NYCT approval to obtain NYC DOB permits. 

3.11 Utilities 

A large number of documented and undocumented utilities exist within and adjacent to the site. Many of 

the utilities will likely require relocation to accommodate construction of the platform foundations. LIRR 

will likely require hand digging or vacuum excavation to determine the exact location of existing utilities to 

remain. 

4 Adjacent Construction Activity 

4.1 East Rail Yard Development 

The East Rail Yard (ERY) Redevelopment project is currently under construction. The ERY construction 

includes completion of the platform over the rail yard, landscaped outdoor spaces, several commercial 

and residential towers, a retail podium, and a cultural building referred to as the Culture Shed. 

4.2 Amtrak Gateway Tunnel 

Amtrak has proposed a new multi-track rail tunnel as part of its Gateway project. The new tunnel will 

extend from Penn Station to New Jersey. The tunnel’s alignment runs northeast-southwest beneath 

Hudson Yards. The first two segments of the tunnel were constructed beneath the ERY between the 

“Terminal West” area of Penn Station and the west side of Eleventh Avenue. The third segment of the 

tunnel is proposed to run from Eleventh Avenue to West 30th Street, within the terra-firma area of the 

WRY, and will to be constructed using cut-and-cover construction. Segment 3 is expected to be 

constructed between 2018 and 2021. Construction within the south end of the WRY will require 

coordination with that of the anticipated Amtrak construction.

5 Proposed Development 

Our understanding of the proposed development is based on discussions with the design team and 

review of the preliminary design plans. 

5.1 Platform 

The proposed development includes construction of a platform over the WRY to support five high-rise 

towers and public space. A brief description of the proposed structures is as follows: 

 Site 1: Located in the northwest part of the platform, Site 1 includes Tower 1A (59-stories) and 

Tower 1B (67-stories), with a connecting podium. The commercial space will occupy the podium 

level and the towers will contain residential units. LIRR facilities and parking areas will occupy the 

platform level. The lower level of the platform may be converted to occupied or utility space at 

sidewalk level. 

 Site 2: Located in the northeast part of the platform, Site 2 includes Tower 2 (28-stories) above a 

podium (18-stories). The commercial space will occupy the podium level and the tower will 

contain residential units. Retail space, a commercial lobby, a loading lock, parking, and utility 

areas will the platform level. 

 Site 3: Located in the south-central portion of the platform, Site 3 includes Tower 3 (57-stories) 

above a podium. The residential and retail space will occupy the podium level and the tower will 

contain residential units. Parking space will occupy the platform level. 

 Site 4: Located in the southeast corner of the platform, Site 4 includes Tower 4 (64-stories) above 

a podium. The residential and retail space will occupy the platform and “lobby” level and the 

podium level and tower will contain residential units. 

 Areas outboard of buildings will include a public plaza with landscaped areas and streets. A 

platform level will be located below the plaza and will house parking, utility space, and LIRR 

support facilities; a lawn area will be located on the far west side of the platform level. 

The proposed platform is a composite-concrete-deck extending from West 33rd Street to the Terra Firma 

parcel and between Eleventh and Twelfth Avenues. The top of the platform will be at about el 28.5 ft to 

el 32.5 ft, and will be supported by columns extending to ground level in the service corridors between 

tracks. The columns are typically spaced 50 feet on center in the north-south direction and 25 feet on 

center in the east-west direction beneath the proposed towers, and 100 feet on center in the north-south 

direction and 25 feet on center in the east-west direction elsewhere. Detailed structural loads were not 

available as of this the date of this report. Service compression loads on columns are anticipated from 

about 5,000 to 10,000 kips beneath the towers and 2,000 to 4,000 kips for platform areas without 

buildings, based on discussions with the MRCE. 

Consideration is being given to removing and replacing the tracks segmentally to allow for construction of 

foundations and tie beams to brace the foundations. Where used, tie beams will need to be constructed 

below the track slab. 

The platform structure will be designed in accordance with the 2014 New York City Building Code 

(NYCBC). 

5.2 LIRR Buildings 

The three existing LIRR support buildings (Transportation, EIC, and Yard Operations) are scheduled for 

demolition and will be reconstructed in their current locations as part of the platform construction. Loads 

for the LIRR buildings have not been developed as of the time of this report. The LIRR buildings are 

subject to the requirements of the 2015 New York State Building Code (NYSBC).

6 Site Development History 

The site lies outboard of the original Manhattan shoreline and has undergone numerous stages of 

development. The area was filled during the mid-nineteenth century and early twentieth century, 

progressively moving the shoreline westward to its current position, west of Twelfth Avenue. The 

shoreline was extended westward in stages, by placing miscellaneous fill into the river, often directly on 

soft river deposits of silt and clay. Numerous piers and bulkheads were present in the site footprint as 

illustrated in Figures 3 through 8. Remnant bulkhead structures and foundations may be present below 

grade across a large area of the WRY and should be anticipated during construction. 

The site predominantly served as rail and storage yards since the mid-1800s. 

7 LOCAL GEOLOGY 

7.1 Bedrock Geology 

The WRY is on Manhattan Island, which is within the southern terminus of the Manhattan Prong of the 

New England Upland province. Bedrock in the vicinity of the site generally consists of granite, schist, and 

gneiss. Bedrock is overlain by glacial and fluvial soil, as well as extensive fill. Although altered by urban 

development, original topography within Manhattan typically mimicked the contours of the underlying 

bedrock. 

According to Baskerville (1994), bedrock stratigraphy in the vicinity of the site is part of the Hartland 

Formation, with rock of the Lower Cambrian (about 500 to 520 million years ago) to Middle Ordovician 

(about 461 to 472 million years ago) age and intrusive rock presumably of the Silurian age (about 416 to 

444 million years ago), consisting of granite and megacrystalline pegmatite. The geologic map for the 

site vicinity is included as Figure 9. Generalized descriptions of rocks mapped in the vicinity of the site 

are: 

Hartland Formation – Interbedded units of (1) gray, fine-grained quartz-feldspar granulite containing minor 

biotite and garnet; (2) fine-to-coarse grained, gray-to-tan weathering, quartz-feldspar-muscovite-biotitegarnet schist (mica schist); (3) dark greenish-black quartz-biotite-hornblende amphibolite. Intrusions of 

granite and pegmatite are common (Baskerville 1994). Metamorphism has resulted in foliation – a 

distinct planar alignment of mineral grains – within rocks of the Hartland Formation. This grain alignment 

is commonly referred to as schistosity in the more platy schistose rock or compositional banding in 

gneissic rocks. Foliation is typically oriented either northwest or southeast and dips steeply within 

Manhattan as discussed by Baskerville, but may be altered locally as a result of folding. 

Granite and Pegmatite – Gray-white-pink medium- to coarse-grained, biotite-muscovite-microcline-quartz 

granite and megacrystalline pegmatite in dikes less than 3 feet thick and sills greater than 3 feet thick. 

Accessory minerals include tourmaline, pyrite, garnet, and epidote. A large sill of intrusive granite is 

mapped north of the site from West 35th Street to West 40th Street; however, historical boring data 

indicates that this granite sill extends farther south than mapped. Boundaries between the intrusive 

granite and Hartland formation rocks are not well-defined as evidenced by intermittent contacts and 

inclusions observed in rock cores throughout the area including in the West Side Yards and Penn Station. 

7.2 Surficial Geology 

The Hudson River is west of the site and historically covered the site prior to filling. The Hudson River 

formed mainly during glaciation about 2.5 million to 12,000 years ago. Southward-advancing ice sheets 

scoured the Hudson River Valley, deepening an existing river channel and removing surficial sediments 

and weathered rock. As the glaciers melted, till (a mixture of boulders, gravel, sand, silt and clay) and 

outwash sands were deposited on top of the scoured bedrock. A subsequent period of erosion removed 

much of the outwash sands and till from the Hudson River Valley. In the last 10,000 years, fluvial 

deposits of sand, silt and clay have covered the remaining glacial deposits. A gradual rise in sea level

has resulted in a decrease in the velocity of the Hudson River. Because of this change in velocity, the 

more recent alluvial deposits consist primarily of silt and clay, while the older alluvial deposits consist 

primarily of fine sand and silt. The historical shoreline and surface water drainage pathways are shown 

on Figure 10. 

8 FEMA Flood Zone 

The Federal Emergency Management Agency (FEMA) Primary Flood Insurance Rate Map (PFIRM), plate 

3604970009G, shows the site is within Zone AE. The AE designation corresponds to “Special Flood 

Hazard Areas” subject to inundation by 1% annual chance flood (i.e. the 100-year flood or base 

flood). The FEMA base flood elevation varies from el 11 ft to 12 ft within the WRY. An excerpt of the 

PFIRM is attached as Figure 11. 

Any structures located below the base flood elevation must be floodproofed in accordance with the 

NYCBC, NYS Building Code, ASCE 24, and all other agencies having jurisdiction. At a minimum, 1 foot 

of free board must be provided above the controlling base flood elevation. We understand that Related 

has elected to use a design flood elevation of el 15 ft. 

We recommend that LIRR be consulted to determine any special flood proofing requirements for the 

design of their reconstructed buildings. 

9 Subsurface Data

Subsurface data for the site was derived from numerous investigations performed within and adjacent to 

the WRY. This information includes borings and cone penetration testing (CPT) data as well as 

laboratory testing of soils and rock. The data includes studies performed by Langan and several other 

entities. The approximate locations of the borings and CPTs are shown in Figure 12. The following 

sections provide a brief overview of the data included in this study. 

9.1 Proposed New York Sports and Convention Center (2004) 

A geotechnical subsurface investigation was performed within the WRY for the design of the proposed 

New York Sports and Convention Center (NYSCC) in 2004. This investigation included 29 geotechnical 

test borings and 24 cone penetration tests (CPT). A laboratory test program was also performed as part 

of the project. 

9.1.1 Borings 

The NYSCC borings (identified as G-#) were drilled within and adjacent to the WRY by Warren George 

Inc. (WGI), of Jersey City, New Jersey between 11 October and 17 December 2004. The borings on the 

tracks were performed with two Acker 2D high-rail, truck-mounted drill rigs. Borings outside of the tracks 

were performed with an Acker 11 truck-mounted drill rig, a CME 55 truck-mounted drill rig, or a DK-50 

track-mounted drill rig. The borings were advanced to depths from 52 to 160 feet below grade. 

Each boring was cleared of utilities by hand or using standard drilling techniques with minimal water and 

no down-pressure on the drill string. The borings were advanced through overburden using mud-rotary 

drilling techniques with tri-cone roller bits and drilling fluid consisting of a mixture of polymer additive and 

water. Temporary flush-joint steel casing was installed through the soils, as required, to stabilize the 

boreholes and prevent fluid loss during drilling. 

The Standard Penetration Test (SPT)1 was performed in general accordance with ASTM D1586. SPT Nvalues1

 and visual soil classifications were recorded by Langan’s engineers. Soils were sampled using a

split-spoon sampler a distance of 2 feet, using a 140-lb hammer free falling from a height of 30 inches.

MAY 1, 2017

standard 2-inch outer-diameter split-spoon sampler. Undisturbed soil samples were obtained using 3-inch 

outer-diameter Shelby tubes in general accordance with ASTM D1587. Rock coring was performed in all 

borings, in accordance with ASTM D2113 using a double-wall core barrel to assist in determining bedrock 

depth, type, and quality. 

Rock core recovery (REC)2 and rock-quality designation (RQD)3 for each core run were logged by our 

inspecting engineers. All recovered soil and rock samples were visually classified in the field. Soil and 

rock classifications, SPT N-values, and other field observations were recorded on the boring logs 

included in Appendix A. 

9.1.2 Cone Penetration Testing 

Cone penetration testing within the WRY included eight standard CPTs (identified as CPT-#) and 

16 seismic cone-penetration tests (identified as SCPT-#). All cone-penetration testing was performed in 

accordance with ASTM D3441 by ConeTec, Inc. of West Berlin, New Jersey between 11 October and 

19 November 2004. All of the test locations were pre-drilled to depths of about 10 feet by WGI to clear for 

utilities. In locations where obstructions were encountered in the fill, WGI returned and drilled to native 

soils. The CPTs were pushed to refusal, encountered at depths varying from about 22 to 111 feet below 

grade. 

Cone-penetration testing consists of pushing an instrumented stainless steel cone through soil 

overburden using hydraulic pressure while continuously collecting data. The standard CPT cone 

measures penetration tip resistance, side friction, and pore water pressure at 5 cm (about 2 inch) 

intervals. The SCPTs also measure shear-wave velocity; a total of 277 seismic tests were performed at 

about 1 meter (about 3.3 feet) intervals. The seismic test involves generating vibrations at the ground 

surface and recording the shear wave’s amplitude and travel time with a geophone mounted in the cone. 

A copy of the ConeTec field report is included in Appendix B.

9.1.3 Laboratory Testing 

A laboratory testing program was performed to evaluate the general engineering index properties of 

select soil samples, as well as strength and compressibility properties of cohesive soils and bedrock as 

part of the NYSCC project. The laboratory test results are included in Appendix C. 

Analyses included: 

 Mechanical Grain Size (9 tests) [ASTM D 1140, D 422] 

 Natural Water Content (92 tests) [ASTM D 2216] 

 Liquid and Plastic (Atterberg) limits (51 tests) [ASTM D 4318] 

 Organic Content (35 tests) [ASTM D 2974] 

 Unconsolidated Undrained (UU) Triaxial Test (10 tests) [ASTM D 2850] 

 Consolidated Undrained (CU) Triaxial Test (2 tests) [ASTM D 4767] 

 Unconfined Compressive Strength of Rock (13 tests) [ASTM D 2938] 

 Consolidation Test (4 tests) [ASTM D 2435]

9.2 Borings by Others 

Numerous investigations were performed by others within and adjacent to the WRY; these investigations 

are summarized in Table 2. This information was used to supplement our data from NYSCC. In general, 

the reported subsurface conditions correlate well with our 2004 study, particularly stratigraphic changes 

and top of rock elevations. In some instances, the historical data lacks engineering data (e.g. N-value, 

REC, RQD, etc) and only documents subsurface stratigraphy. Copies of the historical boring data by 

others are included in Appendix D.

10 SUBSURFACE CONDITIONS 

The general subsurface stratigraphy at the site consists of uncontrolled fill, underlain by consecutive 

layers of clay and silt, sand, glacial till, and bedrock. A brief description of each layer is presented below 

in order of increasing depth. Typical subsurface profiles are attached as Figures 13 through 15. 

10.1 Uncontrolled Fill [Class 7]1

Fill is present beneath the entire site. The fill generally consists of sand with varying amounts of gravel, 

silt, boulders, brick, wood, and other miscellaneous debris. The thickness of the fill varies from about 10 

to 40 feet, generally increasing in depth from east to west. The fill varies significantly with respect to 

content and density from one location to the next. SPT N-values varied from weight of hammer (WOH) to 

100 blows per foot (bpf); however, in many cases the higher recorded N-values were attributed the 

presence of oversized materials (e.g., cobbles, boulders, timber, and other construction debris) and are 

generally not considered to be a representative indicator of in situ density. Blow counts generally 

decrease with depth as the transition into the softer organic clay was approached. 

A void was encountered about 6 feet below grade at boring G-52 (LIRR track 14, about 50 feet west of 

Eleventh Avenue). The void was estimated to be about 5 feet in diameter, and at least 4 feet in height; 

the cause of the void could not be determined and the zone was grouted closed. Boring G-52 was offset 

15 feet east of the original boring and re-drilled. 

The fill is categorized as Class 7 (Uncontrolled Fill) in accordance with the NYCBC.

MAY 1, 2017

10.2 Organic Clay and Clay and Silt [Classes 6, 4c, 5b] 

A stratum of organic clay and clay and silt underlie the fill throughout the site. This stratum is the historical 

river bottom deposit. The thickness of the silt and clay varied from about 10 to 90 feet, increasing from 

east to west. The top of the clay and silt layer varies from about el -5 ft to el -35 ft. 

10.2.1 Organic Clay 

The black-gray organic clay has variable concentrations of silt and trace-amounts of fine sand and 

organic matter, and varies from zero to 40 feet thick. The organic clay was observed primarily on the 

west side of the site. The split spoon sampler typically penetrated this stratum under the weight of the 

drill rods and hammer (WOH). 

Unified Soil Classification System (USCS) descriptions for the organic clay layer include CH (highly 

plastic clay) and OH (organic clay and silt of high plasticity). The organic clay layer is generally 

categorized as NYCBC Class 6 (Soft Clay). 

10.2.2 Silt and Clay 

The organic clay was underlain by gray silt and clay with some shells, trace fine sand, and trace 

concentrations of organics. Interlayered (varved) silt and clay with occasional layers of fine silty sand was 

encountered in several borings, predominantly in the central and northwest corner of the site. Where 

encountered, the silty sand layers were typically 1- to 6-inches thick. The thickness of the silt and clay 

stratum varied from about 10 to 80 feet, increasing in thickness from east to west. N-values in this 

stratum ranged from WOH to 37 blows per foot. Values in excess of 10 blows per foot are likely attributed 

to inclusions of debris near the interface with the fill. 

USCS descriptions for the silt and clay include CH (high plasticity clay) CL (low plasticity clay), MH (high 

plasticity silt), and ML (low plasticity silt). The silt and clay layer is generally categorized as NYCBC Class 

6 (Soft Clay), Class 4c (Medium Clay) and Class 5b (Medium Silt).

10.3 Sand/Till [Classes 6, 3, 5] 

Sand and glacial till was encountered above bedrock at some locations. The thickness of the sand and 

till varied from zero to 35 feet. The top of the sand/till layer varies from about el -12 ft to el -105 ft. 

10.3.1 Sand 

Where encountered, the sand was typically comprised of grey fine sand with varying amounts of silt and 

was up to 30 feet thick. N-values in the sand ranged from 4 to 40 blows per foot. 

USCS classifications for the sand include SP (poorly-graded sand) and SM (silty sand). The sand layer is 

generally categorized as NYCBC Class 6 (Loose Sand) to Class 3a (Dense Sand). 

10.3.2 Glacial Till 

Where encountered, the glacial till was typically comprised of brown, red, and grey silt with variable 

concentrations of coarse to fine sand, gravel, clay with frequent cobbles and boulders. The thickness of 

the till varied from 2 to 11 feet. N-values in the glacial till varied from 22 blows per foot to more than 100 

blows per foot. The higher SPT N-values were likely caused by the presence of gravel, cobbles, and 

boulders. The glacial till appears to be more prevalent on the north side of the site. 

USCS classifications for the glacial till include SM (silty sand), SC (clayey sand), GM (silty sandy gravel), 

and ML (low plasticity silt). The glacial till layer falls within several soil classes per the NYCBC because 

of the constituent variability with respect to location and depth throughout the site, but is generally 

NYCBC Class 3a (Dense Sand) to Class 5a (Dense Silt).

10.4 Bedrock [Classes 1a to 1d] 

Bedrock was encountered from about el -17 ft to -133 ft; the depth to bedrock generally increases from 

east to west. A layer of decomposed rock was encountered at the bedrock surface in some locations. 

Bedrock generally consists of dark gray mica schist, gneissic schist and granulite with intrusions of light 

gray to pink quartz- and feldspar-rich granite and pegmatite. Granite intrusions were observed to vary 

from about 1 to 20 feet thick. Rock core recovery varied from 40 to 100 percent. Rock quality 

designations (RQD) varied from zero to 100 percent. 

Bedrock within the site is generally categorized as NYCBC Class 1a (Hard Rock) and 1b (Medium Hard 

Rock). Zones containing increased weathering and fracturing were observed sporadically near the 

surface and within the rock mass, and are classified as NYCBC Class 1c (Intermediate Rock). Highly 

weathered, highly fractured zones were reported in several borings at the surface and were also 

observed within the rock mass. Clay gouge was often observed in fractures in these more highly 

fractured zones. The highly weathered, highly fractured zones are categorized as NYCBC Class 1d 

(Soft/Decomposed Rock). 

10.5 Groundwater 

Groundwater levels were determined from monitoring wells installed throughout the site. The measured 

groundwater levels varied from as high as el 3.9 ft to as low as el -1.5 ft, but are generally expected to 

vary from about el 0 ft to el 2 ft. Groundwater levels are expected to be tidally influenced along the west 

side of the site because of the proximity to the Hudson River. In addition, groundwater levels are likely to 

fluctuate with seasonal changes and precipitation events. Zones of perched water may be present at 

some locations given the heterogeneous nature of the fill soils. 

11 Seismic Design Parameters 

Seismic design parameters presented herein are in accordance with the 2014 New York City Building 

Code (NYCBC) and 2015 New York State Building Code (NYSBC). 

11.1 Seismic Evaluation 

The site was initially evaluated using the general procedures outlined in the 2014 NYCBC and the 2015 

NYSBC. Based on the general procedures the site was initially classified as Site Class E, but was 

assigned to Site Class F based on the potential for liquefaction. Site Class F requires a site-specific 

seismic study. A site-specific seismic study was subsequently performed to: 1) further evaluate the 

potential for liquefaction; 2) evaluate the potential excess pore pressure development during seismic 

events; and 3) to develop appropriate response spectra and determine the corresponding seismic design 

category for the site. 

Site-specific total and effective stress analyses were performed for the six zones defined by the 

expansion joints shown in Figure 16. These analyses indicate the site’s design spectrum falls along the 

80 percent of Site Class E envelope (minimum spectrum permitted by code) for Zones 1 through 5. The 

design spectrum for Zone 6 falls between the general Site Class E envelope and the 80 percent of Site 

Class E envelope between periods of zero and 1-second, and along the 80 percent of Site Class E 

envelope at periods greater than 1-second. 

We understand the platform is classified as NYCBC Structural Occupancy/Risk Category III. As such, the 

recommended design spectral accelerations obtained from our response spectra result in Seismic Design 

Category C in all six zones. Seismic design parameters are presented in Table 3 and Table 4 below. 

The recommended design response spectra are presented in Figures 17 and 18. The site specific 

seismic study report is included in Appendix E. 

The effective stress analyses suggest that excess pore pressure development is not likely to trigger full 

liquefaction; however, significant softening may occur in fill soils located below the groundwater table.

The excess pore pressures were estimated to vary from zero to about 50 percent. As such, we 

recommend that the structure be designed to accommodate reduced bearing and lateral resistance.

11.2 Design and Construction Considerations 

11.2.1 Platform 

The following bullets briefly summarize significant design and construction considerations for the platform. 

 The design and construction of the platform is subject to the requirements of the 2014 NYCBC. 

 In addition to LIRR, the platform design and construction will be subject to review and approval of 

Amtrak (North River and North Access Tunnels), MTACC/NYCT (No. 7 Line subway), NYCDOT 

(Eleventh Avenue and West 33rd Street viaducts), and Friends of the Highline (Highline). 

 The site is within the mapped FEMA flood hazard area. The FEMA base flood elevation varies 

from el 11 ft to el 12 ft. Structures located below design flood level will need to be floodproofed in 

accordance with the 2014 NYCBC and ASCE 24. 

 Groundwater generally varies from about el -1.5 to el 2.0 ft. Temporary dewatering may be 

necessary for installation of, utilities, pile caps, tie-beams, etc. 

 The subsurface conditions within the site are relatively poor and necessitate a deep foundation 

system. Drilled caissons will be required to support of the platform given the need to large axial 

and lateral loads. 

 The site-specific seismic analyses confirm the platform structure and buildings atop the platform 

fall in Seismic Design Category C. 

 The potential for excess pore pressure development during seismic events will reduce the lateral 

capacity of caissons in some areas of the site. 

 Tie-beams between adjacent caissons are required because the site classifies as seismic design 

category C. Excavations for tie-beams will likely require removal of track slabs, utility relocations, 

and support and protection of adjacent structures (e.g. West 33rd Street retaining wall). 

 A track isolation casing will likely be required by LIRR to mitigate transferring loads from the 

caissons into the track slab. 

 Caissons located within the theoretic influence lines of tunnels bedded in rock may require bond 

breakers. 
HUDSON YARDS 

HYW-PL-LAN-RPT-A-20170501 GEOTECHNICAL REPORT P A G E | 13

MAY 1, 2017

 Means and methods to construct caissons in close proximity of existing tunnels must mitigate 

potential for soil loss and disturbance. We expect that strict tolerances will be required to ensure 

that suitable lateral clearances are maintained between the caissons and tunnels. 

 A detailed monitoring program is necessary to evaluate the performance of adjacent structures, 

the ground, and existing tunnels during platform construction. The monitoring program will be 

subject to review and approval of Amtrak, MTACC/NYCT, LIRR, NYCDOT, and Friends of the 

Highline. 

 Large portions of the rail yard will remain active during platform construction and will require close 

coordination with LIRR. 

11.2.2 LIRR Support Buildings 

The following bullets briefly summarize significant design and construction considerations for the LIRR 

support buildings anticipated for reconstruction under this project. 

 Design of the LIRR support buildings are subject to the requirements of the NYSBC. 

 Driven piles or caissons (mini-caissons) are considered feasible for support the LIRR support 

buildings. Shallow foundations are not considered suitable given the potential for seismically 

induced settlement. 

 The design flood elevation for the LIRR support buildings should be as dictated by LIRR. We 

recommend that LIRR be consulted early in the design process to determine appropriate design 

flood elevations. Structures located below design flood level will need to be floodproofed in 

accordance with the NYSBC and ASCE 24. 

 Floor slabs and walls of permanent structures below the design flood elevation must be designed 

to resist hydrostatic pressures. 

 Floodproofing should to the design flood elevation in accordance with the NYSBC and ASCE 24. 

 Ground anchors may be required where sufficient dead load is not present to accommodate 

hydrostatic forces from either static groundwater or design flood conditions. 

 Groundwater is at shallow depth on the west end of the site; construction dewatering should be 

anticipated where excavating below el 2 ft. 

12 Design Recommendations – Platform 

12.1 Drilled Caissons 

We recommend that the platform be supported by drilled caissons. Caissons consist of a permanent 

steel casing drilled through soil to bedrock, with an uncased socket extending into bedrock. The casing 

and rock socket are filled with steel reinforcing and concrete. Steel reinforcing may consist of rolled steel 

sections, built-up plate steel shapes, and/or rebar cages; however, we expect that use of rebar cages will 

be preferable because of the difficulty splicing core beams (time and space requirements). Caissons 

develop axial load capacity through a combination of peripheral shear resistance between the concrete 

and rock, and end-bearing on the rock. End-bearing should be neglected for caissons less than 18 

inches in diameter. We recommend that the caisson rock sockets be proportioned assuming an 

allowable peripheral bond stress of 200 pounds per square inch (psi) for compression and 100 psi for 

uplift. Additionally, we recommend an allowable end-bearing of 40 tons per square foot (tsf). The 

recommended design values assume rock meeting NYCBC Class 1c or better for rock socket sidewalls 

and NYCBC Class 1b for rock socket bottoms. All rock sockets must be inspected to verify the quality of 

the bedrock before installing reinforcing steel and concreting. We recommend that verification be 

performed through video inspection with a down-the-hole camera or by drilling large diameter cores 

(minimum 85 mm) at the center axis of the caisson in conjunction with borehole geophysical logging 

(acoustic and/or optical televiewer). 
HUDSON YARDS 

HYW-PL-LAN-RPT-A-20170501 GEOTECHNICAL REPORT P A G E | 14

MAY 1, 2017

We understand that caissons varying from 36-inch to 72-inch in diameter are contemplated for support of 

the platform and buildings, with service loads varying from about 4,000 to 15,000 kips, respectively. 

Caissons should be designed to accommodate the combined effects axial loading and bending. Short 

caissons may be subject to development of plastic hinges when transitioning from soil to rock support. 

The shear capacity of such elements should be evaluated and where required, additional shear 

reinforcing should be provided or the casing should be seated further into rock. The effects of excess 

pore water pressure during seismic loading should be considered when evaluating the lateral capacity of 

the caissons. 

12.1.1 Load Tests 

Axial load tests are not required for NYCBC code compliance, but could be used to justify higher 

peripheral bond stresses and end bearing resistance. Load tests performed on rock within the ERY 

demonstrated that higher values are possible and can provide time and cost savings by reducing socket 

bond lengths; however, the rock conditions within the WRY are generally expected to provide a weaker 

response. The cost versus benefit of performing axial load testing will be evaluated with the design team 

and ownership. 

Lateral load tests will be required for caissons that exceed 1 ton of lateral capacity per the NYCBC. At 

least two lateral load tests are required for each caisson diameter and lateral capacity to satisfy NYCBC 

requirements. Given the variable subsurface conditions, load tests should be performed in areas 

containing the “poorest” conditions unless additional load tests are performed to evaluate each area of 

differing subsurface conditions throughout the site. Where caissons of the same diameter contain differing 

quantities of reinforcement or have differing concrete strength, the test caissons should utilize the least 

amount of reinforcement and lowest compressive strength of concrete to provide a lower bound envelope 

of the lateral capacity unless additional load tests are performed for each caisson material configuration. 

Load tests must be performed in accordance with ASTM D3966. 

We recommend that the lateral load test caissons be instrumented with inclinometers, strain gages, or a 

combination thereof to estimate the full-depth deflected shape necessary to back calculate the p-y 

response. The results of load testing should be used to calibrate soil models used for final design of the 

caissons with respect to lateral capacity. 

We believe that it is possible to perform lateral testing on a single intermediate caisson size to calibrate 

software soil models. The allowable capacity of the remaining caisson sizes would then be estimated 

using programs such as Lpile or DFSAP, with an appropriate safety factor. We note that a variance will 

be required from the Department of Buildings in order to forgo testing multiple diameters. We believe that 

such a variance is achievable and this approach is prudent given the logistical challenges of the site and 

cost of such additional testing. 

12.1.2 Group Effects

The caissons should have a minimum center-to-center spacing of at least 2.5 diameters to prevent axial 

group effects. If the minimum center-to-center spacing of caissons is less than 2.5 diameters, analysis 

must be performed to determine if the axial capacity is governed by the caisson group or individual 

caissons 

Lateral group effects should be considered where caisson center to center spacing is less than six 

diameters. 

12.1.3 Drilling Methods 

Caisson installation methods must prevent settlement of material beneath the track slab and minimize 

vibrations. Drilling of the caissons through overburden can be performed using rotary or auger drilling 

techniques. Given the potential for borehole collapse within loose silty soils and bottom heave in soft 
HUDSON YARDS 

HYW-PL-LAN-RPT-A-20170501 GEOTECHNICAL REPORT P A G E | 15

MAY 1, 2017

clays, we recommend that temporary casing and a positive head of water be maintained during drilling. 

Where required a mineral or polymer slurry should be provided to improve bottom stability. In addition, 

we recommend the drill stem be kept inside the casing while drilling through overburden soils to minimize 

the potential for bottom heave or running-sand conditions. The drill stem should be kept inside the casing 

a minimum of 1 foot until the casing is seated into rock. A concrete plug may be necessary to seal the 

casing to rock in areas containing steeply sloping or fractured rock. 

A down-the-hole hammer will be required to efficiently advance the rock socket. Caissons should be 

flushed using water or compressed air (or other approved methods) upon completion of drilling rock 

sockets to remove all debris accumulated on the bottom of the rock socket. Thorough cleaning of the 

bottom of the rock socket is critical for caissons designed with end-bearing, and proper cleaning must be 

verified through inspection, as discussed below. 

Obstructions, such as remnant foundations or bulkheads, and debris in the historical fill, should be 

anticipated throughout the site. The Contractors’ means and methods should consider the need for 

penetrating or bypassing such obstructions. Means to bypass the obstructions may include pre-drilling 

using oversized cased boreholes and then backfilling. We recommend that careful drilling techniques be 

employed to avoid disturbance of these materials. Pre-drilling activities to clear potential obstructions 

must be evaluated relative to possible loss of lateral resistance. We recommend that the contractor be 

precluded from performing pre-drilling in open holes below the groundwater. All pre-drilling areas should 

be backfilled and compacted with an approved material satisfactory to the geotechnical engineer. Where 

possible, pre-drilling should be performed by advancing oversized casing with the hole cleaned out and 

backfilled with Controlled Low Strength Material (CLSM) prior to withdrawal of the casing. 

12.1.4 Reinforcing Steel Splices 

Deformed bar and threaded bar cages can be spliced using staggered mechanical couplers or 

conventional lap splices. We recommend that only mechanical couplers capable of developing full 

capacity of the bars be used for tension elements. 

The splice connection between core beams must be capable of achieving the necessary stress and 

moment transfer at the splice depth. Splices should be milled to bear should utilize either complete joint 

penetration (CJP) or partial joint penetration (PJP) welds as necessary. Bolted connections may also be 

considered, but such mechanical connections could inhibit constructability because the splice can require 

significant area within the caisson section, thus potentially limiting concrete flow or installation of concrete 

tremie tubes. 

12.1.5 Centralizers 

All reinforcing steel must be centered within the caisson. Where rebar cages are implemented, 

centralizers should be spaced no more than 10 feet on center. Steel core beams should be provided with 

at least one centralizer at the base. The tops of core beams should be aligned at the top of the casing 

using either a template or by manual wedges. 

12.1.6 Concrete Placement 

Concrete should be placed as soon as possible following cleaning and within 72 hours of inspecting the 

rock socket. If placement is delayed the socket must be reinspected. Concrete must be placed using 

tremie methods, and must be performed in a continuous operation. Concrete must consist of a flowable 

mixture and must remain workable throughout the anticipated duration of the pour. We recommend the 

use of self-consolidating concretes.

12.1.7 Foundation Settlement 

Caissons settlements will generally be similar to that of elastic shortening. We expect that such 

movements will be up to about 1⁄2-inch based on the caisson configurations currently considered by the 

project structural engineer. 

12.1.8 Minimum Clearances (Amtrak and MTA Tunnel Structures) 

Coordination with Amtrak and the MTA will be required to determine the minimum allowable clear 

distances (lateral and vertical) between caissons and tunnel structures. At this time, we suggest that a 

minimum lateral clearance of 10 feet (measured at the ground surface) be carried for caissons adjacent to 

the Amtrak North River tunnels. Closer clearances are possible at the Amtrak North Access tunnel 

because this structure is at shall depth and can readily be exposed to verify clearances. Lateral 

clearances to the No. 7 Line subway are not expected to govern as the tunnels fall greater than 10 feet 

beyond the east property line. 

Finite element method analyses will be necessary to demonstrate that the caissons do not negatively 

impact the existing tunnel structures and justify the vertical location of rock socket bond zones relative to 

the existing tunnels. At this time, we recommend that that bond zones for caissons adjacent to the North 

River and North Access tunnels be assumed start below a theoretic influence line starting at the tunnel 

invert and projecting outward and upward from the tunnel at an inclination of 2V:1H; caissons adjacent to 

the No. 7 Line should be assumed to have bond zones starting at 3 feet below the top of rock. 

The locations and extents of the existing tunnels must be verified in the field by the contractor’s licensed 

surveyor prior to drilling. 

12.1.9 Plumbness Monitoring 

We recommend that all caissons located less than 25 feet from existing tunnels be monitored during 

construction to ensure the caissons are installed plumb. Standard construction tolerances dictate that the 

caissons deviate no more than 2 percent from vertical alignment. Where required, casings should be 

survey monitored prior to initial penetration to ensure proper vertical alignment. Thereafter, plumbness of 

the caissons should be measured incrementally during the drilling process using borehole geophysical 

methods suitable for determining azimuth and inclination (e.g. gyroscopic methods). 

12.1.10 Bond Breaker 

Bond breakers may be necessary to prevent shedding loads onto the tunnels. The specific requirements 

for bond breakers should be determined for each governing agency, and should be evaluated based on 

the actual caisson layout and loading. Bond breakers may not be necessary in areas where caissons 

bear well above tunnels founded in rock (e.g. No. 7 Line). Justification for eliminating such bond breakers 

is generally demonstrated through a finite element method analysis. 

While several methods are available to provide a bond breaker, we recommend that the specific means 

and methods be proposed by the Contractor. Conceptually, a bond breaker can be provided by: 1) 

drilling a temporarily cased oversized borehole to the intended top of rock socket; 2) installing a smaller 

bituminous coated permanent casing inside the temporary casing; 3) grouting the annulus, and removal 

of the temporary casing, and; 4) drilling the final rock socket from within the remaining permanent casing. 

Alternatively, bond breakers can be accomplished by hanging a bituminous coated pipe (isolation casing) 

within a portion of the rock socket. Often the isolation casing is supported from the reinforcing cage or 

core beam. 

12.1.11 Track Isolation Casing 

The LIRR has previously stated that caissons within the tracks must be installed using isolation casings to 

prevent transferring lateral loads to the adjacent tracks. This requirement should be confirmed with the 

LIRR. The isolation casing will likely be 6 inches larger in diameter than the permanent casing and will 
HUDSON YARDS 

HYW-PL-LAN-RPT-A-20170501 GEOTECHNICAL REPORT P A G E | 17

MAY 1, 2017

extend a minimum depth of 4 feet below the top of the caisson. The isolation casings locations should be 

excavated using hand tools for the first 6 feet due the presence of utilities beneath the track slab. The 

annulus between the isolation casing and permanent casing must be filled with compressible elastic foam 

or other means to seal the gap without allowing load transfer. 

13 Design Recommendations – LIRR support Buildings 

13.1 Foundation Discussion 

Driven steel piles and mini-caissons are considered feasible for support of the LIRR support buildings. 

Shallow foundations are not recommended given the potential for seismically induced settlements. 

13.2 Driven Piles 

Driven steel piles, end-bearing on bedrock (NYCBC Class 1c or better) are considered feasible for 

support of LIRR support buildings. The capacity of end-bearing piles will generally be controlled by the 

structural capacity of the pile section. Where implemented, we recommend that driven piles consist of Hpiles conforming to ASTM A572 Grade 50. The piles should be sized to accommodate axial and lateral 

loading requirements for the building and driving stresses necessary to bypass timber and rubble that 

may be present within fill soils. Pipe piles may be an alternative, but are generally expected to be more 

difficult to drive through the fills soils. We expect that H-piles can achieve axial compressive capacities of 

about 150 to 200 tons each. Settlements of H-piles are expected to be less than 1-inch (including elastic 

shortening). 

All H-piles should be fitted with protective points such as the Hard-Bite manufactured by Associated Pile 

Fitting Corp. or equivalent. 

The contractor should perform and submit a wave-equation analysis (WEAP), including driving stresses in 

the pile, once a final pile section and driving hammer are selected to ensure the pile is not overstressed 

during installation and to develop driving criteria. The WEAP is necessary to help evaluate if the 

proposed pile and driving system can install the pile through the till and decomposed rock to achieve the 

allowable capacity without damaging the pile. 

13.2.1 Index Piles and Compression Load Tests 

At the beginning of pile driving operations, we recommend installing a minimum of eight index piles to 

evaluate driving conditions across the building footprint and the need for predrilling to bypass 

obstructions. All index piles shall be installed to final bearing and be monitored with a Pile Driving 

Analyzer (PDA). The purpose of the PDA is to determine the actual energy delivered to the pile, and to 

confirm the pile stresses during driving are not excessive. The data will also be used to estimate the 

ultimate pile capacity. The index piles may be used, if properly installed, as production piles. 

At least one pile load test will be required to satisfy the requirements of the NYSBC for driven pile 

capacities exceeding 40 tons. Load tests may be performed in accordance with ASTM D1143 or D4945. 

For consistency with NYC practice, we recommend a minimum of two static load tests be performed in 

accordance with ASTM D1143. 

Production piles should be installed in the same manner, using the same driving equipment as the 

successfully load-tested piles. 

13.3 Mini-caissons 

Mini-caissons (defined as micropiles per the NYSBC) may be used in lieu of driven piles for support of the 

LIRR support buildings. Mini-caissons are similar to large diameter caissons, except the diameter is 

limited to less than 14-inches. Mini-caisson rock sockets should be proportioned in accordance with the 

recommendations previously outlined for drilled caissons. The structural design of mini-caissons should 
HUDSON YARDS 

HYW-PL-LAN-RPT-A-20170501 GEOTECHNICAL REPORT P A G E | 18

MAY 1, 2017

conform to the requirements for micropiles as outlined in the NYSBC. Mini-caisson elements should be 

designed to accommodate the combined effects axial loading and bending. 

Axial load testing is not required for mini-caissons under the NYSBC. In addition, lateral load testing is 

not required under the NYSBC; however, we recommend that a minimum of two lateral load tests be 

performed in accordance ASTM D3966. All rock sockets should be verified with either down-hole 

cameras or via borings. 

Settlements of mini-caissons will be governed by elastic shortening and are generally expected to be less 

than 1⁄2-inch. 

13.4 Floor Slabs 

Floor slabs and sump pits at the LIRR support buildings should be designed as structural pressure slabs 

designed assuming hydrostatic uplift corresponding to the design flood elevation dictated by LIRR. 

Where possible, pressure slabs should be keyed into walls and should be cast with integral water-stops at 

all joints (PVC “dumbbells” and post-construction grouting tubes). Pressure slabs should be waterproofed 

as per the recommendations presented herein and those of the project waterproofing consultant. 

13.5 Below Grade Walls 

Any permanent below grade walls will be subjected to lateral pressures from soil, groundwater 

(hydrostatic), and surcharge loads. Restrained walls (walls that are braced against moving/rotating, such 

as basement walls) should be designed for at-rest earth pressure. The soil parameters shown in Table 5 

should be used for the design of lateral earth pressure loads on restrained below grade walls.

Table 5: Below Grade Wall Soil Design Parameters (Restrained Walls) 

Parameter Recommended Value

Wall Backfill: Fill

Typical Soil Unit Weight: 120 pcf

Friction Angle: 30 Degrees

Coefficient of At-Rest Earth Pressure: 0.50

Design Water Level As directed by LIRR 

13.6 Permanent Groundwater Control 

We recommend that all walls and slabs of the LIRR buildings below the design flood elevation be 

completely encapsulated using a membrane type waterproofing system, such as those manufactured by 

Grace Construction Products (GCP) Applied Technologies, Inc., Carlisle Coatings and Waterproofing, 

Inc., or Laurenco Systems, Inc. The use of bentonite waterproofing or negative-side crystalline 

waterproofing is not recommended as a means of primary waterproofing. 

Horizontal waterproofing membranes should be installed on a minimum 2-inch-thick lean concrete mud 

slab placed over an approved subgrade to provide a smooth and uniform application surface. Vertically 

applied waterproofing membranes should extend up to the design flood elevation. Substrate preparation 

should be per the manufacturer’s recommendation. 

Quality control is critical to a successful waterproofing project. The waterproofing installation should be 

inspected daily, especially during placement of reinforcement for the floor slabs and perimeter walls. Any 

holes or tears should be repaired in accordance with the manufacturer’s recommendations and utility 

penetrations should be carefully sealed. All seams, including separations between wall and slab 

membranes should be checked for tightness. We recommend that the waterproofing manufacturer 
HUDSON YARDS 

HYW-PL-LAN-RPT-A-20170501 GEOTECHNICAL REPORT P A G E | 19

MAY 1, 2017

inspect the waterproofing operations during construction and approve all work prior to placement of 

concrete. 

14 Construction Recommendations 

14.1 Excavations

We anticipate that excavation through soil will be required for utility relocations, and construction of pile 

caps and grade beams. Excavations in soil can be accomplished with conventional earthmoving 

equipment (i.e., track-hoes, etc). Obstructions such as remnant foundations, timber cribbing/bulkheads, 

abandoned and live utilities, rubble, and boulders should be anticipated when excavating or installing 

deep foundations through soils. Larger equipment may be required to remove obstructions. Means and 

methods for the removal of obstructions must be coordinated against the design to mitigate the potential 

for reducing axial or lateral capacity of foundation elements. 

All excavations should be benched or sloped in accordance with applicable OSHA standards. Where 

required, temporary excavation support should be installed as per the recommendations presented 

herein. 

Care must be exercised if pre-excavating to clear potential obstructions at caisson locations to avoid 

disturbance that can reduce lateral resistance of soils and ultimately reduce caisson lateral capacity. We 

recommend that the contractor be precluded from performing pre-excavation in open holes below 

groundwater. All areas of pre-excavation should be backfilled and compacted with an approved material 

satisfactory to the geotechnical engineer. Where possible, pre-excavation should be performed by 

advancing oversized casing with the hole cleaned out and backfilled with CLSM. 

14.2 Temporary Support of Excavation 

Temporary excavation support may be required to accommodate utility relocations and construction of 

pile caps and tie-beams. The contractor or responsible subcontractor should design temporary 

construction support of excavation in accordance with all OSHA, local, state and federal safety 

regulations. 

We recommend that support of excavation be designed assuming the soil parameters provided in 

Table 6. We also recommend that SOE should be designed assuming the following minimum loading 

conditions: 

 Braced Excavations - Free draining or dewatered walls should be designed using a uniform 

pressure distribution of 28H psf, where H is the total height of the wall. Walls that are not free 

draining or are not dewatered should also be designed using a uniform pressure of 28H psf, 

where H is the total height of the wall plus a triangular hydrostatic pressure of 62.4 psf per ft 

below the groundwater table (el 2.0 ft). 

 Lateral pressures from surface loads should assume vehicular loading. Surface surcharges 

should be added as an inverted triangle having a maximum pressure at the ground surface equal 

to one-half of the vertical surface load (minimum 600 psf). Lateral surcharge pressure can be 

reduced to zero at a depth of 15 ft below ground surface. 

 Lateral pressures resulting from adjacent structures and railway loading should be determined 

using elastic methods and should be added to the above loads. Railway surcharges should be in 

accordance with the AREMA Manual for Railway Engineering and any additional LIRR 

requirements. 

 Temporary construction loads such as cranes and other equipment are not considered herein and 

must be assessed on a case-by-case basis.

14.3 Temporary Construction Dewatering 

Localized excavations for utility relocation and tie-beams may be below the static groundwater level; 

therefore, temporary construction dewatering may be required. Controlling the groundwater will be critical 

in order to allow for subgrade preparation. We expect that groundwater should be controllable with sump 

pumps during foundation work. 

All groundwater discharged from the site into NYC sewers will require temporary dewatering permits from 

the NYCDEP. Treatment may be required where the groundwater is found insufficient for meeting water 

quality standards dictated by the regulatory agencies having jurisdiction. 

14.4 Soil Subgrades 

Pile cap, grade beam, floor slab, and track subgrades should be level and clear of debris, standing or 

frozen water, and other deleterious materials. Soils should be excavated with care to avoid disturbance 

that may reduce axial or lateral resistance. We recommend that the final 12 inches of excavation be 

performed with flat bladed buckets in open areas and by hand in confined areas. Subgrades should be 

protected from the effects of frost, precipitation, groundwater and surface water run-off and construction 

until concrete is cast. As such, we recommend that the Contractor limit the area of exposed subgrade to 

prevent deterioration of the bearing conditions; however, excavations should be made large enough to 

allow passage of a compactor. 

Areas disturbed by excavation and other areas found to be unacceptable should be re-compacted, or 

stabilized as necessary, using geogrid or geotextiles in conjunction with compacted structural fill or 

gravel. CLSM or lean concrete may also be used. The subgrade following placement of fill and 

compaction should be firm and unyielding under the weight of heavy equipment without evidence of 

rutting, pumping, or heaving. Vibratory compaction shall not be performed on soils that are not within 

2 percent of optimum moisture content. Compaction should be discontinued in the event that soils are 

observed to “pump or heave” due to wet conditions. 

Following compaction, subgrades should be capped with crushed stone fill. This material will help protect 

the subgrade from degradation and can be used to assist in conveyance of water during dewatering 

activities. A mud slab may also be cast to provide protection and may be required to provide a suitable 

substrate for waterproofing in building areas.

HYW-PL-LAN-RPT-A-20170501 GEOTECHNICAL REPORT P A G E | 21

MAY 1, 2017

14.5 Fill Materials, Placement, and Compaction 

Structural fill is expected around tie-beams and at the LIRR support buildings. Additional fill should be 

limited to utility trenches, minor earthwork, or roadway reconstruction. Structural fill should consist of a 

well-graded durable granular material having a maximum particle size of 4 inches in any dimension, and 

no more than 10 percent fines passing the No. 200 sieve. All fill should be free of trash, debris, roots, 

vegetation, peat, or other deleterious materials and should be approved by the geotechnical engineer 

prior to placement. Lean concrete or controlled low-strength material (CLSM) may be substituted for 

structural fill. 

Fill should be placed in uniform loose lifts not exceeding 12 inches in open areas that can be compacted 

using heavy compaction equipment, and 6 inches in confined areas where hand operated equipment is 

required. All fill should be compacted to at least 95 percent of the soil’s maximum dry density as 

determined by ASTM D1557. The water content at the time of compaction should be within a 2 percent of 

the optimum value determined by ASTM D1557. 

Fill should not be placed on subgrades not inspected and approved by the geotechnical engineer. All fill 

must meet the requirements of the approved Remedial Action Work Plan (see below). 

14.6 Restrictive Declaration Soil Management 

The site is being developed under the oversight of the New York City Office of Environmental 

Remediation (NYCOER) pursuant to a restrictive declaration (RD) executed by WRY Tenant LLC on 

10 April 2014. The restrictive declaration includes requirements for hazardous materials testing, air 

emissions control, and noise attenuation. Soil management (excavation, staging, transport, disposal and 

importing) must follow all requirements of the NYCOER-approved Remedial Action Work Plan (RAWP). 

14.7 Monitoring 

We recommend that a detailed monitoring program be developed and incorporated into the Contract 

Documents. Monitoring should include means to measure both structural movement and vibrations from 

construction operations. The type and locations of specific monitoring equipment, threshold values, and 

durations should be developed based on review of the anticipated construction means and methods in 

conjunction with proximity to existing structures and utilities. The purpose of performing monitoring is to 

provide reasonable feedback to the engineer as to performance of the contractor with respect to 

protecting existing structures and utilities, and to assess any necessary changes to means and methods 

of construction. 

Specific requirements for monitoring are likely to be imposed by governing agencies including NYCDOT, 

MTACC/NYCT, Amtrak, Friends of the Highline. Critical structures which are likely to require monitoring 

include: 

1. the existing LIRR tracks to remain in service, 

2. the Highline, 

3. the West 33rd Street retaining wall and viaduct, 

4. the Eleventh Avenue viaduct, 

5. the Amtrak North Access Tunnel (NAT), 

6. the Amtrak North River Tunnels (NRTs), 

7. the Gateway Tunnel, and

8. the MTA No. 7 Line subway 

We recommend that a dialog be established with all governing agencies prior to construction to determine 

specific monitoring requirements. 
HUDSON YARDS 

HYW-PL-LAN-RPT-A-20170501 GEOTECHNICAL REPORT P A G E | 22

MAY 1, 2017

The monitoring program would likely include optical surveying, seismographs (vibration monitoring), and 

crack gauges. We recommend that a plan be developed after discussion with the governing agencies 

and further development of design drawings. Given the expected duration for foundation construction, 

remote sensors capable of relaying data in real-time via wireless communications should be used. The 

monitoring plan should address means and methods for measuring ground and structural deformation, 

and vibration levels. We recommend that all monitoring be performed by a third-party consultant 

independent of the contractor; however, the contractor should reserve the right to perform additional 

monitoring. Monitoring should be performed throughout drilling, excavation and platform construction. 

14.8 Preconstruction Conditions Documentation 

We recommend that preconstruction conditions documentation be performed, for any structures to 

remain, about one month prior to commencing construction activities. Each agency will likely require 

documentation of their facilities. This would most likely include the tracks, Highline, West 33rd Street 

retaining wall and viaduct, Eleventh Avenue viaduct, existing Amtrak tunnels, and MTA No. 7 Line 

Extension structures. The purpose of these observations is to provide photographic and video 

documentation representative of general existing conditions and identify obvious visual deficiencies. The 

preconditions observations should also identify areas requiring specific monitoring during construction. 

Structural integrity is not addressed in such documentation. This baseline information is often critical in 

the event of future damage claims resulting from construction activities. 

14.9 Special Inspections 

Excavation and foundation work are subject to various Special Inspections as per the requirements 

outlined in Chapter 17 of the NYCBC and the Rules of the City of New York and any requirements of the 

LIRR. Construction activities that require geotechnical quality control inspections include installation of 

the caisson foundations, driven piles, mini-caissons, excavation, subgrades, and lateral support systems, 

backfilling, and compaction. This work must be performed under the inspection of a qualified 

geotechnical engineer. The inspecting engineer should be familiar with the subsurface conditions, as well 

as the proposed and existing construction onsite. We recommend that all inspectors meet the minimum 

requisite qualifications outlined in 1RCNY 101-06. 

15 Construction Documents 

Technical specifications and design drawings should incorporate the recommendations contained herein 

to ensure that subsurface conditions and other geotechnical issues at the site are adequately addressed 

in the construction documents. 

We recommend that the language in foundation and earthwork specifications emphasize the potential for 

encountering buried obstructions during excavation with the intent of mitigating change-of-conditions 

claims arising during construction. All excavation should be assumed to be unclassified such that the 

contractor is responsible for providing the necessary performance of the foundation system regardless of 

conditions encountered. 

16 Owner and Contractor Responsibilities 

The Contractor is responsible for construction quality control, which includes satisfactorily constructing the 

foundation system and any associated temporary works to achieve the design intent while not adversely 

impacting or causing loss of support to neighboring property, structures, utilities, roadways, etc. 

Construction activities that can alter the existing ground conditions such as excavation, fill placement, 

foundation construction, ground improvement, pile driving/drilling, dewatering, etc. can also induce 

stresses, vibrations, and movements in nearby structures and utilities, and disturb occupants. 

Contractors are solely responsible to ensure that their activities will not adversely affect the structures and 

utilities, and will not disturb occupants. Contractors must also take all necessary measures to protect the 

existing structures, utilities, etc during construction. By using this report, the Owner agrees that Langan 

will not be held responsible for any damage to adjacent structures, utilities, etc.
