Innovative and Cost-effective Vertical Movement in Multistory Construction in Lagos, Nigeria

Abstract

In Nigeria, Lagos, the city, becomes a bustling megacity, and multistory buildings serve as crucial solutions for housing shortages and the need for commercial infrastructure. The city has led to a surge in the demand for multistory buildings due to rapid population growth, economic development, and the need to optimise limited land space. This study investigates innovative and cost-effective approaches to the vertical movement of personnel and materials in multistory building construction in Lagos, Nigeria. As urbanisation accelerates and the demand for high-rise buildings grows, effective vertical transportation systems are essential for improving construction efficiency and reducing operational costs. The research employs a qualitative methodology, incorporating interviews with 20 construction professionals, including construction managers, architects, engineers, and logistics managers, along with site observations and case studies from active construction projects in Lagos.  The findings reveal that traditional systems such as cranes and lifts dominate the industry. However, emerging alternatives like modular hoists, automated lifts, and even drones are gaining traction due to their potential for cost savings and increased efficiency. However, the adoption of these innovative systems is hindered by challenges such as high initial investment costs, safety concerns, limited technical knowledge, and a lack of infrastructure for maintenance. The study highlights the need to shift towards more sustainable and affordable vertical transport solutions. It also recommends strategies to improve safety standards, increase awareness, and provide targeted training to ensure these innovative approaches can be more widely adopted and successfully implemented in Lagos' construction sector. To meet Lagos’ vertical building demands, construction firms must adopt smarter, more sustainable vertical movement systems.
