New Construction Pile Caps

The Chance® new construction pile caps are designed for use with the Chance Type SS square shaft and Type RS round shaft helical piles for embedment in cast-in-place concrete foundations. Each new construction pile cap consists of either one bearing plate and one steel tube sleeve that are factory welded together to form the cap, or one bearing plate, two rebars and one steel tube sleeve that are factory-welded together. The plate-type pile caps are designed to be used in spread footings, grade beams, structural slabs, and reinforced concrete pile caps. The rebar

cap is designed to be used in grade beams and reinforced pile caps. The concrete foundation and the interaction of the pile shaft, new construction pile cap, and concrete footing for moment transfer, as applicable, must be designed and justified with due consideration to all applicable limit states and the direction and eccentricity of applied loads, including reactions provided by the brackets, acting on the concrete foundation.
