1.2 SUBMITTALS

A. General: Submittals shall be according to \[Section 01009 - General
Information and Requirements.\] \[and\] \[Section 01330 - Submittal
Procedures.\] \[and\] \[Section 01331 - Certificates.\]

B. Equipment Literature: Submit three copies of the descriptions of the
pile driving equipment to be used on this project. Include details of
the pile hammer, power plant, leads, cushion material, and helmet.

C. Certificates of Conformance: Submit three copies of written
certification from the supplier of the sheet piles to be used on this
project that they conform to the requirements of this specification
section.

1.3 DELIVERY, STORAGE, AND HANDLING

A. Storage: Prevent damage to coatings and prevent corrosion prior to
installation.

B. Handling: Use handling holes. Handle long length piles with care to
prevent damage.

[PART 2: PRODUCTS]{.underline}

2.1 MATERIALS

A. Sheet Piles: Steel shall conform to ASTM A 328. Piles shall have a
minimum section modulus per foot (300 mm), wall of 10 inch^3^
(250 mm^3^). Pile edges shall be of such design and condition that when
in place, they will be interlocked throughout their length. Pile ends
shall be square and blunt, as received from the mill or squarely cut.
Piles shall have a minimum thickness of 0.375 inch (9.50 mm).

[PART 3: EXECUTION]{.underline}

3.1 INSTALLATION

A. Pile Hammers: Shall have a delivered force or energy suitable for the
total weight of the pile and the character of subsurface material to be
encountered. Pile hammers having delivered dynamic forces or energies
less than the following may be used with the approval of the Contracting
Officer:

Vibratory: 12 tons (11.000 kg)

Steam or air: 5,000 ft - lbs (8,000 Nm)

Diesel: 9,000 ft - lbs (12,000 Nm)

B. Diesel Powered Hammers: Shall be used at the rate recommended by the
manufacturer throughout the entire driving period. Repair damage to
piling caused by use of a pile hammer with excess delivered force or
energy.

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

D. Templates: Shall be suitable for aligning, supporting, and
maintaining sheet piling in the correct position during setting and
driving. Use a system of structural framing sufficiently rigid to resist
lateral and driving forces. Framing shall adequately support the sheet
piling until design tip elevation is achieved. Provide at least two
levels of support, preferably not less than 20 feet (6100 mm) apart.
Templates shall not move when supporting sheet piling. Fit templates
with wood blocking to bear against the web of each alternate sheet pile.
Hold the sheet pile at the design location alignment. Provide outer
template straps or other restraints as necessary to prevent the sheets
from warping or wandering from the alignment. Mark templates for the
location of the leading edge of every fourth sheet pile. If two guide
marks cannot be seen, other means shall be used to keep the sheet pile
vertical along its leading edge.

E. Pile Driving: Maintain piling vertical during driving. Drive piles to
tip elevation shown. Sheet piles shall be driven so as to prevent damage
to the piles and to provide a continuous closure of sheet piles. Drive
individual piles incrementally sequenced so the tip of sheet piles shall
not be more than 4 ft (1,300 mm ) below that of adjacent sheet piles.
When the penetration resistance exceeds five blows per inch (25 mm), the
tip of sheet piles shall not be more than \[2\] feet(\[600\] mm) below
adjacent sheet piles.

F. Jetting of Piles: Will be permitted only with the written approval of
the Contracting Officer.

G. Splicing Piles: Will not be permitted.

H. 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.

I. Tolerances in Driving: Drive piles with a variation from vertical of
not more than 1/4 inch per foot (22 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. Re-drive heaved piles to the required
tip elevation.

J. Cutting of Piles: Cut off piles at elevations indicated by method
approved in writing by the Contracting Officer.

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.
