EVALUATING THE COST-EFFECTIVESS OF MODULALR CONSTRUCTION IN THE PROVISION OF MASS HOUSING IN ABUJA.

ABSTRACT The persistent housing deficit in Abuja remains a pressing challenge, with conventional construction methods proving inadequate for affordable and timely housing delivery. This study evaluates the cost-effectiveness of modular construction as an alternative strategy for mass housing provision in the Federal Capital Territory. The objectives were to examine the extent of adoption and usage of modular construction for mass housing in Abuja, to compare its cost with traditional construction methods, and to identify the challenges affecting its costeffectiveness.The study employed a descriptive survey research design, drawing data from 83 construction professionals across public and private organizations. Structured questionnaires were used to capture perspectives on adoption levels, cost implications, and barriers to implementation. Descriptive statistics (mean, standard deviation, and ranking) assessed perceptions. Actual adoption remained modest. Respondents perceived modular construction as incurring higher initial costs (M = 4.19) and transportation challenges (M = 4.03), but lower lifecycle maintenance costs (M = 2.88), underscoring its long-term economic viability. The major challenges identified were high upfront costs (M = 4.25), lack of skilled labour (M = 4.10), and regulatory constraints (M = 3.87). Supply chain disruptions and limited technical expertise further constrained effective adoption. However, government tax incentives (M = 4.47), professional training programs (M = 4.31), and regulatory reforms (M = 4.16) emerged as the most effective strategies to overcome these barriers. The study concludes that modular construction offers substantial potential to address Abuja’s housing deficit if systemic barriers are addressed. Its cost paradox higher initial costs but reduced lifecycle expenses highlights the need for supportive policy frameworks, financial incentives, and targeted skill development programs. The research recommends a dual intervention approach: top-down policy reforms to reduce institutional and regulatory barriers, and bottom-up capacity-building to strengthen workforce expertise, supply chain efficiency, and industry collaboration. By aligning these strategies, modular construction can become a sustainable pathway for affordable, timely, and scalable housing.
