All steel not entirely
encased in concrete shall be either all stainless steel (SS304 or SS316) or all
hot dip galvanized (A136) steel (A36 or 572). This includes tie rods, all-threads,
couplers, washers, nuts, carriage bolts and lag screws. No mixing of steel
types will be allowed. If tie-rods will
be hot-dip-galvinized, first four(4) feet of the tie-rod(end closest to the
water) shall be field coated with coal tar epoxy or other approved bitumastic
coating.

noted on plans.
2.0
Delivery and Storage
Upon
delivery of materials to site, contractor shall visually inspect all materials
for defects or damage. If serious defect or damage is detected, contractor
shall notify engineer immediately. Store bundled sheet piling on a relatively
level surface with a slight pitch to allow water to drain. Contractor should
not break bundled sheets until ready for immediate installation.
3.0
Submittals
Contractor
is to provide submittals as noted in 3.1 and 3.3 with initial bid package. Bid
packages without the indicated submittals will be rejected.
3.1
Complete
descriptions of sheet piling driving equipment including hammers, extractors,
protection caps and other installation appurtenances.
3.2
Material
Certification – Prior to shipment, manufacturer shall provide Letter of
Certification from a registered professional engineer assuring that the sheet
pile meets requirements set forth in Section 1.1.
3.3
Contractor
is responsible for obtaining sheet pile test data as described in section 1.1.3
(footnotes A,B,C,D & E) for submittal.
4.0
Installation
4.1
Install
driving guide, template or wale system to aid in driving a straight and plumb
wall. A “two level” template as well as front and rear wale/bracing system is
strongly suggested for tough and/or deep driving situations.
4.2
Drive
sheet piling (preferably in pairs) by “Driving in Steps” or “Gang Driving”.
Direction of installation should be with the male side of the sheet when possible.
Mandrel, helmet or drive shoes may be required if driving through hard soil
strata or obstructions. Water jet by displacement of soil shall only be used
with non-cohesive soils (sands & gravels). Water jet shall not be used if
driving through clay, silts or immediately adjacent to an existing structure
without the written approval from the engineer. Water may be introduced to
induce lubrication and liquefaction during installation. It is very important
that the contractor drives sheets to required embedment depth. Under no
circumstances shall the contractor cut-off or install shorter sheets without
written authorization from engineer or the owner. Adequate precautions shall be
taken to ensure that piles are driven plumb. Sheet piling shall not be driven
more than ˝ inch per foot out of plumb in the plane of the wall, nor more than
1/16 inch per foot “out” of plumb perpendicular to the plane of the wall, nor
more than 1 inch per foot “in” of plumb perpendicular to the plane of the wall.
4.3
Piles
driven out of interlock with adjacent piles or otherwise damaged shall be
removed and replaced by new piles at the contractor’s expense.
4.4
Install
wales, tie rods and deadmen as noted on the project plans.
4.5
Install
drainage system and weep holes (if required).
4.6
Backfill
behind sheet pile in level compacted lifts (12” max. lift thickness).
Compaction of backfill shall be 95% based on ASTM D698. Testing of compaction
shall be taken a minimum of 4’ behind the wall. Maintain heavy equipment at
least four feet from back of sheeting.
5.0
Payment
Payment
for vinyl sheet pile wall shall be based on linear foot of bulkhead acceptably
installed. Payment shall be full compensation for supply and installation of
sheet pile, wales, cap, hardware, tie rods, anchoring system and backfill.
