INTEGRATING LOCAL SUPPLY CHAIN DYNAMICS TO ENHANCE SUSTAINABILITY AND PERFORMANCE IN NIGERIA’S RESIDENTIAL CONSTRUCTION SECTOR

Abstract

Nigeria’s residential construction sector faces critical challenges, including fragmented supply chain practices, heavy reliance on imported materials, and limited adoption of advanced technologies. These inefficiencies result in prolonged project timelines, increased costs, and environmental degradation, underscoring the need for systemic reform. This study examines the integration of local supply chain dynamics as a strategy to enhance sustainability and performance within the sector. A mixed-methods approach was adopted, incorporating surveys, interviews, and simulated data analyses. Quantitative data collected from 150 construction professionals revealed that only 27.4% of materials used in the sector are sourced locally, while qualitative insights from 30 stakeholders identified key barriers, such as variability in material quality (82%) and inadequate supplier capacity (76%). The findings highlight that integrating local materials can deliver significant environmental and economic benefits. For example, project costs can be reduced by 22% and carbon emissions by 35% through the use of locally sourced materials. A case study of a housing project in Kaduna State demonstrated that utilizing local materials improved project timelines by 35% and lowered costs by 20%. Simulated scenario analyses further supported these findings, showing that increased reliance on local materials enhances efficiency and reduces logistical challenges. Nevertheless, structural barriers such as insufficient policy support and low digital tool adoption must be addressed through targeted interventions. This study recommends the establishment of standardized certification systems, capacity-building programs, and financial incentives to support local supply chain integration. It also underscores the need for digital transformation to optimize supply chain operations and foster sustainable practices. The findings provide practical recommendations and a replicable framework for stakeholders seeking to enhance construction performance while aligning with global sustainability goals.
