1 This document covers provisions for design and construction of combined piled raft foundations (CPRF) for residential and industrial structures, store houses, storage tanks, etc. . This composite foundation which combines load carrying capabilities of raft and pile foundations together may be implemented in any of the following situations: a) Where a raft cannot provide an adequate bearing capacity due to excessive settlement beyond permissible limit; and b) Where the raft is unable to perform under the serviceability requirement (for example, if settlement exceeds permissible limit for raft) of the structure. In both cases, piles can be introduced below the raft to improve the safety against failure or to reduce the settlement to an acceptable level.
