Due process and contractor selection for public works in Nigera

Contract procurement processes have a lot of challenges in the construction industry. These challenges are evident in procedures used for selection of contractors and consequent, performance of projects. This study explores the challenges of Due Process Policy Model (DPPM) procedures for the selection of contractors for public projects between 2002 and 2008 in Nigeria. The procedures mandate certain categories of the procurement of public construction contracts to undergo a sequence of activities. Such procedures include advertisement, prequalification, short-listing, invitation, tender action and project execution. Observations are made on procedures of selection of contractors for 47 projects using DPPM. Moreover, interviews were conducted to seek clarifications on some of the challenges identified in DPPM processes. Arguably, DPPM is gaining more popularity in Africa. Thus, observations made on the challenges of DPPM will improve its capacity for adoption within and outside Africa; motivate innovative procurement processes, with significant impact on international contract procurement policy makers and contract procurement officers. International contractors willing to explore the growing capacity of the construction market in Africa will discover significant and appropriate understanding of the basic requirements of DPPM.
