F. DESIGN NOTES:

1\. **DRAWING DATA REQUIRED:**

2\. **TECHNICAL NOTES**

A. Hot-rolled steel sheet piling sections are suitable for applications
where interlocked joint strength in tension or section stability is a
primary design requirement. Section stability (Biaxial Stress) is a
consideration in highly stressed applications only.

B. Hot-rolled, light-duty steel sheet piling sections and cpld-formed
steel sheet piling sections are suitable for average depth applications
such as trench sheeting and bulkheads in moderate water depths. They are
not suitable for applications where they are subjected to high
concentrated wale loads or where interlocked joint strength in tension
or section stability is a primary design requirement.

C. Cold-formed, light gauge steel sheet piling sections are suitable for
applications with a required minimum sheeting thickness of 0.250 inch
(6.35 mm) or less, low bending and corrosion resistance, and minimal
required interlocked joint strength in tension. The corrosion resistance
of light gauge sheet piling can be increased by applying a protective
coating.

D. For applications in salt or brackish water use the most economical of
a 690 steel sheet piling which offers greater corrosive resistance or a
328 steel sheet piling with a protective coating in the splash zone. A
protective coating should be applied to a 690 sheet piling in the splash
zone of waterway bulkheads located in salt or brackish water.

E. Consideration should be given in design to the use if a 572
high-strength steel sheet piling where economical. In floodwall
applications the allowable working stress should not exceed 0.5 of the
yield strength of the steel. In other applications the allowable working
stress should not exceed 0.6 of the yield strength of the steel.

F. The following tables list section properties of commercially
available sheet piling. Based upon the design requirements of each
piling section select the most suitable corresponding section from these
tables or other commercial sources and place the pertinent section
properties of this section on the drawings as minimum requirements.

[PART 3: EXECUTION]{.underline}

3.1 INSTALLATION

\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*

INSERT DESIRED ENERGY RATINGS IN THIS PARAGRAPH. HAMMERS WITH ENERGY
RATINGS BETWEEN 8,750 AND 16,000 FOOT POUNDS (11,860 AND 21,700 J) ARE
RECOMMENDED.

\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*

A. Pile Hammers: Hammers shall be steam, air, or diesel drop,
single-acting, double-acting, differential-acting \[, or vibratory\]
type. The driving energy of the hammers shall be between \[[
]{.underline}\] and \[[ ]{.underline}\] foot-pounds (\[[ ]{.underline}\]
and \[[ ]{.underline}\] joules) as recommended by the manufacturer for
the piling weights and subsurface materials to be encountered.

B. Pile Protection: Use a protective cap during driving to prevent
damage to the top of the sheet piling.

C. Placing: Temporary wales, templates, \[master pilings,\] \[current
deflectors,\] or guide structures suitable for aligning, supporting, and
maintaining sheet piling in the correct position during setting and
driving shall be provided to ensure that the pilings are placed and
driven to the correct alignment. At least two templates shall be used in
placing each piling and the maximum spacing of the templates shall not
exceed 20 feet (6 m). The templates shall be sufficiently rigid to
resist lateral and driving forces without movement and shall adequately
support the pilings until design tip elevation is achieved. Pilings
properly placed and driven shall be interlocked throughout their length
with adjacent pilings to form a continuous diaphragm throughout the
length of run of piling wall.

D. Driving: Sheet piling shall be driven with the proper sized hammer
and by approved methods so as not to subject the pilings to damage and
to ensure proper interlocking throughout their length. Driving hammers
shall be maintained in proper alignment during driving operations by use
of leads or guides attached to the hammer. Adequate precautions shall be
taken to ensure that the pilings are driven plumb. Individual pilings
shall be driven in sequential order in increments of depth to the
required elevation or depth. The tip of a sheet pile shall not be more
than \[4 feet (1.3 m)\] \[[ ]{.underline} feet ([ ]{.underline} m)\]
below the tip of the adjacent piling. Pilings damaged during driving or
driven out of interlock shall be removed and replaced at the
Contractor's expense. Pilings shall be driven without the aid of a water
jet \[unless otherwise authorized\]. \[Authorized jetting shall be
performed on both sides of the pilings simultaneously and must be
discontinued at least \[5 feet (1.5 m)\] \[[ ]{.underline} feet ([
]{.underline} m)\] before final seating of the pilings.\]

E. Jetting: Jetting of piles will be permitted only with the written
approval of the Contracting Officer. \[Jetting equipment shall have
sufficient capacity to deliver consistent pressure to at least two
removable or fixed jets of either the water or combination air-water
type. Water jets shall be designed so that the discharge volume and
pressure are sufficient to freely erode the material under and adjacent
to the piling and shall not affect the lateral stability of the final
in-place pile.\]

F. Splices: Sheet piles driven below the required top elevation and
sheet piles damaged by driving and cut off to permit further driving
shall be extended at no additional cost to the Government. \[If directed
pilings shall be spliced to be driven to greater depths than shown and
extended upward to the required elevation.\] Pilings adjoining spliced
pilings shall be full length unless otherwise approved. \[If splices are
allowed in adjoining pilings, the splices must be spaced at least \[[
]{.underline} feet ([ ]{.underline} m) apart in elevation.\] \[Splicing
of pilings shall be as indicated.\] Ends of pilings to be spliced shall
be squared before splicing to eliminate dips or camber. Pilings shall be
spliced with concentric alignment of the interlocks so that there are no
discontinuities, dips or camber at the abutting interlocks. Spliced
pilings shall be free sliding and able to obtain the maximum swing with
contiguous pilings. The tops of pilings excessively damaged during
driving shall be trimmed when directed at no cost to the Government.
Piling cut-offs shall become the property of the Contractor and shall be
removed from the site. Holes cut in the pilings for bolts, rods, or
\[utilities,\] \[[ ]{.underline},\] drains shall be done in a neat and
workmanlike manner. Holes in the piling shall be drilled or may be
burned and reamed by approved methods which will not damage the
surrounding steel. A straight edge shall be used in cuts made by burning
to avoid nicks.

G. Welding: Shop and field welding, qualification of welding procedures,
welders, and welding operators shall be according to AWS D 1.1, for the
type of welding required.

H. Cutoffs: Sheet piles driven to refusal or to the point where
additional penetration cannot be attained and extending above the
required top elevation shall be cut off to the required elevation. The
cutoffs shall be made in clean, straight lines and within the stated
tolerances.

I. Tolerances in Driving: Sheet pile shall be driven with a variation
from vertical of not more than 1/4 inch per foot (20 mm per meter).
Place the pile so the face shall not be more than 4 inches (100 mm) from
vertical alignment at any point. Top of pile at elevation of cut-off
shall be within 1/2 inch (12 mm) horizontally and 2 inches (50 mm)
vertically of the location indicated. Manipulation of piles to force
them into position will not be permitted. Check piles for heave during
the driving operation. Re-drive all piles that heave more than 1/4 inch
(6 mm). Re-drive heaved piles to the specified tip elevation.

J. Inspection: Any sheet piling found to be damaged to the extent that
its usefulness is impaired or found to be out of interlock shall be
removed and replaced at the Contractor's expense.

3.2 REMOVAL

A. Pulling: \[The method of pulling sheet pilings shall be approved by
the Contracting Officer. Pulling holes shall be provided in pilings as
required and extractors shall be of suitable type and size. Exercise
care in pulling pilings to avoid damaging piling interlocks and adjacent
construction. If the Contracting Officer determines that adjacent
permanent construction has been damaged during pulling, the Contractor
shall repair that construction at no cost to the Government. The pilings
shall be pulled one sheet at a time. The Contractor will not be paid for
the removal of pilings damaged beyond structural use because of improper
care employed during pulling.\]

3.3 FIELD QUALITY CONTROL

A. Requirements: The Contractor shall maintain a record for each sheet
pile. Indicate on the installation record installation dates and time,
type and size of hammer, rate of operation, total driving time,
dimensions of driving helmet and cap used, blows required per foot (300
mm) for each foot (300 mm) of penetration, final driving resistance in
blows for final 6 inches (150 mm ), pile locations, tip elevations,
ground elevations, cut-off elevations and re-heading or cutting of
piles. Record unusual behavior during driving. Submit complete records
to the Contracting Officer.
