I'm reviewing a contractor submittal for cold weather concreting procedure for cast in place piles. The piles are 18 inch diameter monotubes; one location calls for 65' long piles; the other is 90' long. This is a bridge project in the NYC area.
The contractor is proposing to heat the area using light bulbs - yes, light bulbs. My feeling is that this is unnecessary & ineffective. He's proposing to maintain the concrete temperature during placement at around 60 degrees F. I would imagine that after the first few feet from grade the ground temperature would actually be warmer. ACI 306 R10 doesn't address piles.
Any thoughts?
