An International Analysis of Project Delivery Systems for Public Works Projects

Abstract

Project Delivery Systems (PDS) for public works projects can be summarized in only a few (depending mainly on the project stages they cover, which may even include the financing), but the different names and singularities that can be found in current literature are considerably diverse, and this is the main motivation behind the work that is being presented. This work is an international review of existing PDS for public works, covering both traditional and innovative models, some of which are still being developed. Specifically, the aim has been to construct a PDS international classification, for what several factors such as names, parties, applicability, advantages, disadvantages and distribution of responsabilities (assuming the act of contracting as the allocation of obligations, rights and risks among all parties) have been analysed. Then, the equivalence between these PDS and those defined by the Spanish Public Contracs Law has been stablished and an analysis of PDS used in Spain has been conducted.
