Contractors Perceptions of Effects of Project Overhead Costs on Building Project Performance in South-South of Nigeria
Abstract: This study assesses
12 types of project overhead costs, 6 methods of allocation and 15 factors
which affect project overhead costs in South-South of Nigeria. The objective is
to compare small and medium contractors’ perception of the methods of allocation,
factors affecting project overhead costs and the effect of the types of project
overhead costs on cost, time and quality of the projects. Data were obtained
through 501 structured questionnaires administered to small and medium
contractors and analysed using mean item score, and Mann-Whitney U test. The
results reveal that contractors perceive that supervision costs, cost of
rework, equipment management costs, general field expenses, and temporary works
costs were prominent overheads affecting cost, time, and quality performance of
projects. There is no difference in the contractors’ perceptions of issues
affecting overhead costs. It is recommended that contractors should give
adequate priority to significant project overheads and their influencing factors.
