The Drawbacks of Modular Construction: An Expert's Perspective

As an expert in the construction industry, I have seen the rise of modular construction and its advantages over traditional on-site projects. However, it is important to also acknowledge the disadvantages that come with this unique building process. One of the main benefits of modular construction is the efficient storage of materials. In crowded urban environments like Philadelphia, space is limited and organizing and moving materials can be a challenge. This can lead to disorder, slow down work, and even create theft problems.

By building the modules in a factory, construction sites can remain cleaner and safer, providing more space to work and move freely. In the past, one of the biggest drawbacks of modular construction was its perceived lack of quality. As the manufacturing process was still in its early stages, the resulting structures were often subpar compared to traditional on-site projects. However, as processes have been refined and modular construction has gained more traction, manufacturers have implemented stricter quality control measures on their assembly lines. It is important to note that regardless of where the construction takes place, the maximum size of modular units is limited to 16 feet (4.87 meters) wide and 75 feet (22.86 meters) long.

This is due to transportation limitations, which can also impact the design options for larger rooms.

Modular construction

involves constructing a building off-site in 3D modules and then assembling them on site to create the desired structure. While this process offers many benefits, it also makes the loan process more complicated compared to traditional on-site construction. In the past, modular structures were often associated with low-quality products and were even referred to as glorified military barracks. This negative perception of modular construction can also create challenges when it comes to obtaining necessary permits and inspections. While this may vary from state to state, it all stems from the belief that modular constructions do not meet building standards.

It is worth noting that there are other types of off-site construction that are not modular, but that is a topic for another article. In some cases, the cost of transportation alone can make up for the difference in costs between modular and conventional construction. Modular construction is also known by other terms such as “volumetric modular”, “3D modular”, or simply “off-site” construction. However, there is only one way to get a traditionally built structure for a similar price to that of modular construction, and that is by purchasing an old building. In off-site construction, and specifically in modular construction, a significant portion of the project is manufactured outside of the actual building site.

This controlled environment also eliminates concerns about weather conditions delaying the construction of modular units. When planning for a modular construction project, it is crucial to have the “perfect terrain” where the modules can fit together seamlessly. According to a recent study from the United Kingdom, modular construction can result in a material reduction of up to 90%. Additionally, there is less downtime when working on modular construction projects, making them more efficient overall.
