(d) Cutting of the piles will be specified as required by the design.
(e) Driving shoes and the manner of attachment will be specified if these are required by the
(4) Refer to the following examples of guide specifications.
(a) Steel H-piles. CEGS-02360 covers the requirements for procurement, installation, and
testing of steel H-piles.
(b) Round Timber Piles. CEGS-02361 covers the requirements for round timber piles for fresh
water and marine use.
(c) Prestressed Concrete Piles. CEGS-02362 covers the requirements for prestressed
concrete piles for fresh water and marine use.
(d) Cast-In-Place Concrete Piles with Steel Casing. CEGS-02363 covers the requirements for
procurement, installation, and testing of cast-in-place concrete piles utilizing steel casing.
(e) Wood and Cast-In-Place Concrete Composite Piles. CEGS-02365 covers the
requirements for composite, wood on cast-in-place concrete piles.
b. Site Constructibility. The site should be prepared for optimum construction efficiency.
(1) Topography of Land Sites. The site should be prepared for efficient movement of the pile rig,
for access to and from the site, for delivery of materials, and for storage of equipment and materials.
(a) The site should have adequate drainage to prevent water from ponding. Dewatering will be
provided unless specifications allow for wet installation.
(b) The construction area should be level to facilitate driving of the piles, unless construction is
required on a slope. Sloping surfaces may require field adjustment of the pile location if the actual surface
differs from the reference plane used in the plans to show the pile location.
(2) Surface Soils. The top soil should be gravel, sands, or clays with low plasticity index PI < 12
and liquid limit LL < 35 to provide mobility. Lime can be sprinkled on the surface of high plasticity clays to
improve mobility in wet weather.
(3) Overhead Clearance. The pile driving rig, boom, leaders, and clearance required when raising
and placing the pile in the leader should be determined and checked to be sure that clearance at the site is
(4) Coordination. Proper scheduling of delivery of equipment and materials is required to provide
continuous operation of the work.
(a) Site preparation should be completed on schedule to avoid delays in delivery of materials
(b) Piles to be driven should be prepared by completing any preparatory splicing, cutting, and
inspection prior to the time of actual installation.
c. Production of the Pile Foundation. Installation of the pile foundation requires systematic criteria to
optimize productivity and minimize problems.
