The Risks of Modular Construction: An Expert's Perspective

As an expert in the construction industry, I have seen the rise of modular construction and its potential to revolutionize the way we build. However, with any new method comes unique risks that must be carefully considered when purchasing insurance coverage. These risks include transportation, defects in the manufacturing process, off-site coverage, theft, vandalism, and errors and omissions during assembly and installation. To better understand these risks, my team and I conducted a study using Failure Mode and Effects Analysis (FMEA). This method allowed us to identify the most critical risk factors that have a high impact on the implementation of modular construction.

We also ruled out risks that do not significantly affect the process. Our survey questionnaire was sent to experts with knowledge and experience in off-site modular and prefabricated construction through various platforms such as ResearchGate, LinkedIn, and company and academic websites. The results were eye-opening. One of the most critical risks we identified was the lack of skills and experience in modular construction. This is mainly due to the innovative nature of external modular construction in the Pakistani construction industry. While our study focused on risks within the supply chain, it is important to note that there may be other risk factors in other segments of the modular construction process. To gather insights from industry experts, we formed an initial panel consisting of three professionals from off-site modular and prefabricated construction companies and two experts from the academic world who have conducted research on off-site construction.

Through their expertise, we were able to gain a deeper understanding of the risks involved in modular construction. Despite these risks, I firmly believe that modular construction has the potential to promote environmental sustainability and mitigate climate change. By using this alternative method, we can reduce waste and energy consumption, leading to a more sustainable future. However, there are still challenges that need to be addressed. For example, detailed engineering in a combined cycle installation that uses modularization must be completed three to four months in advance, depending on the schedule. This requires careful planning and coordination among all stakeholders. While some modular construction companies have failed, such as Katerra due to the impacts of COVID-19, many others have succeeded.

This is because modular components are manufactured in controlled factory environments, ensuring high-quality and efficient production. Our study has provided valuable insights for professionals in the construction industry. By highlighting and eliminating risks related to the planning and execution of modular construction, we can ensure a smoother and more successful process. One of the main challenges in the modular construction supply chain is its highly fragmented nature. With multiple stages involved, there are several stakeholders with their own values, goals, and objectives. However, I believe that a wider adoption of modular construction can help solve the growing problem of environmental sustainability. In Asia, Japan is leading the way in off-site modular construction, with construction companies producing approximately 70,000 prefabricated homes each year.

This shows the potential for modular construction to become a mainstream method of building in the future. After identifying the risks involved in modular construction, it is crucial to invite experts to determine their importance based on their impact on the implementation process. By doing so, we can better understand and mitigate these risks. In conclusion, as an expert in the construction industry, I have seen firsthand the potential of modular construction. However, it is important to acknowledge and address the risks involved in order to ensure a successful and sustainable future for this innovative method of building.
