The Pros and Cons of Modular Design in Construction

As an expert in the construction industry, I have seen the rise of modular design and construction over the years. With Marriott's highly publicized initiative and the expected growth of the modular construction industry, it is clear that this method of delivering buildings is here to stay. However, like any other construction method, there are both advantages and disadvantages to consider when using modular design. Modular construction involves manufacturing the components of a structure in a factory and then assembling them on site. This process has its own set of challenges, such as transportation costs and the risk of damage during transport.

However, as developers become more comfortable with the process and all parties involved become more familiar with it, we can expect to see more companies opting for modular design. One of the main advantages of modular construction is its efficiency. Work in the factory and on site can be performed simultaneously, which can save time and money. This is especially beneficial for projects with tight deadlines. Additionally, modular design allows for easier integration as the components are already pre-designed and do not require calibration or additional electronic components. Another advantage of modular construction is its environmental impact.

With increasing concerns about sustainability in the industry, modular construction offers a solution to limit waste produced in each project. A case study conducted by WRAP UK suggests that modular construction can reduce on-site material waste by up to 90% compared to traditional construction methods. However, like any other construction method, there are also disadvantages to consider when using modular design. One major disadvantage is the limited flexibility in design. Modular construction involves mass production of components, making it more suitable for projects such as apartment buildings, hotels, and sub-homes.

Custom designs and sizes may not be feasible with this method. Additionally, the cost of modular construction can be higher compared to traditional construction methods. For buildings taller than four floors, steel uprights are required, which can significantly increase the cost. This makes modular construction less affordable for smaller projects. So why are more and more companies building modular structures? The answer lies in the potential cost savings and efficiency that this method offers. While it may not be suitable for all types of projects, modular construction can be a great option for certain types of buildings.
