4.12 CURING: <br />Cover forms with moisture - retaining cover and apply heat in uniform <br />manner. Embed thermocouples in piles and connect through central <br />computer to electrically heated test cylinders for constant monitoring of curing <br />' temperatures and to insure that test cylinders and piles are heated equally. <br />' 4.13 STRIPPING AND HANDLING: <br />When a test cylinder made from the concrete pour for the piles <br />involved reaches the minimum release strength specified, detension strands <br />gradually and simultaneously so as to maintain internal stresses uniform <br />across the pile cross sections. Bum strands flush with ends of piles. Handle <br />' and transport piles as described in paragraph 1.05 above. Do not drive piles <br />until they have reached both their required 28 day strength and a minimum age <br />of 10 days. <br />4.14 FINISHES: <br />Piles with minor imperfections which do not impair the structural <br />' integrity of the pile, such as small surface holes caused by air bubbles, <br />color variations, form joint marks, and minor chips and spalls will be accepted as <br />is. Marina guide piles shall be sacked to five feet below extreme <br />low water. Piles with defects such as honeycomb which could reduce the <br />' structural capacity of the pile will be accepted only if repaired to the <br />Engineers satisfaction. <br />TS -22 <br />RJG08103ISUNNY ISLESITECHSPECS <br />
