Abstract

This study examines contractor performance in project execution among Indigenous Construction Firms (ICFs) operating within the Victoria Island–Ibeju-Lekki corridor of Lagos State, Nigeria. Although contractor performance has received increasing attention in construction management research, there is limited empirical evidence on the factors influencing project execution among indigenous firms in this region. The study therefore investigates the key success factors and constraints affecting contractor performance during project delivery. A quantitative survey design was adopted, and fifty-five (55) structured questionnaires were randomly administered to construction professionals involved in project execution within the study area. Data were analysed using descriptive statistical techniques, including mean score ranking and percentile grading, to determine the relative importance of the identified factors. The findings indicate that the contractor–client relationship is the most significant factor influencing successful project execution, with a mean score of 4.56. This is followed by site management ability (4.22) and project management techniques (4.09). Working within budget recorded the lowest mean score (3.56). The study further identifies inadequate funding, inflation, delayed payments, poor relationships among consultants, changes in government administration, and contractor registration category as the major factors affecting contractor performance during project execution. The study is limited to indigenous construction firms operating in Lagos State and does not compare their performance with that of expatriate firms or firms in other regions. The findings provide practical insights for government agencies, clients, and policymakers seeking to improve project delivery outcomes. Strengthening contractor–client relationships, enhancing site management and project management capabilities, and addressing funding and payment challenges can improve contractor performance and enhance the competitiveness of indigenous construction firms in Nigeria.
