Pros and Cons of Modular Construction

Modular construction is the construction of building structures using modular units that are manufactured at a factory away from the real site. The modular units are transported from the factory to the site and assembled sequentially, to obtain the final structure.

This article encompasses the important pros and expected costs while performing modular construction.

Pros of Modular Construction

1. Modular Construction Cost-Effective

Modular construction employs modular units that are manufactured at a standard scale in similar numbers. Hence, they bring economy in not requiring formwork, scaffolding, casting, and related tedious processes. Hence, compared to the conventional construction process, modular construction is cheap.

2. Modular Construction is Fast

The process involves assembling and fixing the modular units at the site. They are performed with special officers and personnel. 

3. Modular Construction Cause Less Delay

Conventional construction is affected by weather conditions. Modular construction enables modular units to be fabricated in standard conditions following strict quality standards. Hence, there is no chance of delay in projects.

4. Modular Construction is Flexible

Every modular construction project can be renovated from scratch. Except for the foundation, all other modular layouts can be changed to the new design and plans.

5. Modular Construction Enable Superior Acoustics and Better Interiors

Prefabricated modules unlike traditional construction elements, come with unique acoustic features and they become more flexible with the interiors.

6. Modular Construction is Safer

Considering the safety of workers, modular construction just demands the placing of modules. It does not demand high-risk operations of workers like working at heights. Modular construction hence reduces the risk of injuries and is hence safer. 

7. Modular Construction Produce Less Waste

Modules are pre-planned and pre-built. All the required elements are on the site for assembly. This construction, therefore, deals with fewer raw materials and hence reduces waste.

Cons of Modular Construction

The major cons of modular construction are:
  1. Modular construction demand an efficient transportation system to transport modular unit safely to the site. 
  2. Modular construction limits the size of modules constructed. If the client demands a larger size room, usually larger than 5 x 3 m, the manufacture of the units becomes tough. 
  3. Modular construction best suits only a regular and rectangular construction site. 
  4. Certain local authorities of the country limit modular construction.
