This Architectural Drawing is AutoCAD 2d drawing Details of reinforcement pile cap Capacity. With the benefit of using pile joints, precast concrete piles can be driven to lengths longer than 30mx. Often concrete precast piles can be driven down to 30m, however, in special circumstances, such as offshore projects, piles can be driven down to a maximum of 150m. Depth of deep foundation depend on applied load on structure If the load on foundation is 500KN, minimum depth is 3.5m to 4.5m, If the load on foundation is in the range of 2000KN to 3000KN, minimum depth for pile foundation is 6.0m to 20.0m with pile caps.
