Modular method of construction in developing countries: the underlying challenges

Modular construction has been identified as a major part of the continuous improvement being experienced in site procedures and construction processes globally. Few construction projects are being executed using modular building components in developing countries. This study is aimed at assessing the challenges to the implementation of the modular method of construction (MMC) with a focus on developing countries using two major states in Nigeria as a case study. A quantitative research approach was adopted with the design of a questionnaire survey. The study engaged construction professionals such as Quantity Surveyors, Architects, Engineers, Builders and Project Managers in Nigeria. Data retrieved were analysed using percentile, mean item score, Kruskal-Wallis H-Test as well as exploratory factor analysis. The findings showed that construction practitioners are faced with the challenge of finding a compromise between the cost of the project and the value obtainable by using MMC. The challenges were further classified into construction industry practices, client concerns and site characteristics. Practically, the study revealed the need for the proper enlightenment of both construction practitioners and clients with regards to the inherent value of the MMC. This involves the inclusion of MMC requirements in the client’s information requirement for the construction project, the tender pre-qualification questionnaire (PQQ), and the contractor’s technical method statement for the construction project. Theoretically, the study serves as a good foundation for future research seeking to explore the use of MMC in developing countries. The study will assist construction organisations as well as the industry at large in shaping their policies to accommodate the use of innovative methods of construction by understanding the challenges that might hinder its effective implementation.
