Modular Construction and Sustainable Project Developments in the Nigerian Construction Sector

Abstract

Abstract
Purpose – Modular construction (MC) contributes to the circular economy by promoting the reuse and recycling of building materials. The aim of this study is to investigate the application of modular construction, with a view to enhance the management of construction sustainably.

Design– Survey research design was employed to carry out this study in Lagos State, Nigeria. The population of the study is construction professionals who have been involved in modular construction projects. Questionnaires were used to collect data from the respondents. A purposive sampling technique was used to select a sample size of 500 professionals. Frequency, percentage, mean, rank, standard deviation and analysis of variance (ANOVA) were used to analyse the data.

Research Limitation and Implications – Responses were gotten from various professionals knowledgeable about modular construction to achieve valid results that can be generalised in the construction industry.

Findings – The findings reveal that volumetric and temporary modular types are the most available of the 11 investigated, with mean of 3.23 and 3.16 respectively; and the topmost sustainability benefits of MC is minimisation of environmental impact and the promotion of sustainability with a mean of 3.81.

Conclusion, Practical and Theoretical Implication – It is concluded that there are as many as nine modular construction types known and available in the Nigerian construction industry. It implies that the awareness of this type of construction is high in Nigeria. The study recommends that wider awareness of the different types of modular construction projects should be created among all stakeholders in the construction sector. This can be done through seminars, webinars and conferences for the populace.
