4.Experience and Recommendation

Three types of contractual approach have been used forNPP stations, namely:

•The turnkey approach, where a single contractor or a consortium of contractors takes the overall technical responsibility for the construction work

•The split-package approach, where the technical responsibility is divided between a relatively small number of contractors, each building a large section of the plant.

•The multi-contract approach, where the owner or his architect-engineer (A/E) assumes the overall responsibility for detail engineering and constructing the plant. The A/E typically issues a large number of contracts.
