Pros & Cons of Modular Construction

Modular construction is arguably a faster, smarter, and greener method compared to traditional construction methods. Modular construction is the process by which the sections of a house or building are pre-engineered and manufactured off-site within factories that have controlled conditions. The modules are then transported to the site where they are fastened side-by-side or stacked together using inter-module connections. The structures can be built for commercial or residential purposes, can reach towering heights, and can yield creative designs. To many people, it’s the future of construction.

But how viable is modular construction for your project? Whether you are seeking to use modular construction to expand your property or to build something from scratch, this article takes you a step closer to making an informed decision. We will cover the downsides and benefits of modular construction.

Let’s get started!

The Pros of Modular Construction

Many consider modular construction as the best solution for rising demands in the construction industry. But why? It all boils down to these benefits:

1. Faster Process

All else being equal, modular construction can deliver projects 20 - 50% faster than traditional construction. A lot of the remaining benefits listed in this article hinge on this fact. The process is a lot faster because unlike traditional construction where one phase is dependent on the completion of the previous one, modular construction is able to have phases completed simultaneously. 

In traditional construction, site developments and foundations have to be laid down before building construction can commence. But in modular construction, these two can progress simultaneously because the modules are being put together off-site. 

2. Lower Cost

Modular construction can cut costs by up to 20 - 30%. The faster process contributes massively to these savings. Labour costs are lowered as well because this construction process relies more on factory workers who build the modules and less on individual tradesmen. 

3. Increased Safety

In traditional construction, the building’s framework is usually erected first before walls are put into place. This equates to a higher probability of accidents like falling tools or debris. And no matter how trained the contractors are, accidents can cause them to have a fall as well. Some insurance policies would cover such accidents but if you want to reduce the chances of anyone getting hurt in the first place, you’d want to consider modular construction. 

4. Lessened Vulnerability to Bad Weather

Bad weather can delay the completion of projects if you employ traditional construction. It would be unsafe and can even damage the structures being built. Therefore, another time-saving and cost-saving attribute of modular construction is its lessened vulnerability to bad weather. 

The modules come on-site, sturdy and completed. From there, it’s only a matter of fastening them into place. The sturdiness of the modules and the simplicity of the process makes modular construction less susceptible to disruptions due to bad weather. 

5. High Quality

Modules are made with high-quality materials and under the controlled environments of the factory. And because modules arrive on-site as completed sections of the structure, there is less likelihood of moisture from precipitation getting into the walls, floors, or other parts of the building. 

6. Environmentally Friendly

Modules are made in factories where materials can be efficiently used, cross-utilized, and recycled when possible. This makes the process more environmentally friendly than traditional methods. 

7. Decreased Traffic, Dust, & Disturbance

Tying back to the fact that modules arrive at the site as completed sections, this means there is less disturbance in general. There won’t be a parade of trucks containing raw materials coming to the site and stalling traffic. There won’t be long hours of loud construction tools and dust flying in all places. For this reason, many homeowners and business owners choose modular construction for their projects. 

The Cons of Modular Construction

Though modular construction is a cutting-edge solution that addresses multiple problems that traditional construction faces, there are still a few downsides:

1. Delays If There are Sudden Design Changes

The success of modular construction relies on careful planning. With the right design in place, the construction of the modules can progress on schedule and the entire project will be completed on time. However, modules are built to fit with each other. Due to this, sudden changes to the design or rethinking a large part of the design will likely cause delays - as this could mean that entire modules would need to be redone. 

2. Size Restrictions on the Modules

The size of the modules is restricted because it needs to be transported to the site as a completed piece. Though modular construction can adjust to all kinds of designs, the size restriction of the modules is definitely a factor to be considered. 

3. Less Resale Value

A current challenge that modular construction is facing is lack of faith. This is generally because of the lack of awareness around it. Additionally, being a relatively new solution makes it subject to some scrutiny. The lack of faith in modular construction means that properties built using modular construction will have a comparatively reduced resale value. 

And there you have it! These are the pros and cons of modular construction.
