<br /> PILING COSTS , , , Setting up and dismantling a job depends ,vainly on the size of
<br /> equipment needed and the difficulty of access to the 'ob. or a small residential job or
<br /> boat dock where light piling is used and a mobile rip cFor
<br /> run up to the work,setupand
<br /> dismantling may amount to only a few hundred dol rs, while for a large apartmet-ob
<br /> far from a shipping point and requiring piecemeal movement of heavy equipment, the
<br /> cost ,night run twice the average as shown. when placement is in wet conditions,
<br /> dverfront, ,marshland, over water, etc,,the costs should be increased 25% to 50%.
<br /> Where light residential piles are used as common practice, the typical installed costs
<br /> have ranged as low as $2.40 per linear-foot for one hundred tapered wood piles to
<br /> $8.05 er linear foot for composition wood pole and concrete-lined ppipe over water,and
<br /> $17.1 per linear foot for fifteen 12"precast concrete piles plus 5, 25 for setup costs
<br /> in wetlands.
<br /> For pile tests, add $65 to$230 per ton of load per test life.
