In the construction industry today, the two most widely used methods for constructing a building are prefabricated (modular construction) and precast (traditional) methods, and it is sometimes difficult to differentiate between prefabricated and precast buildings.

Prefabricated construction is a technology-based method whereby building parts are constructed in a different area from the site, usually a factory. The factory is generally in a controlled area. This is done to assure the quality and safety of products. The parts are then transported to the construction site and assembled there.

Precast buildings are also known as the traditional method. Here, all building parts are assembled and constructed only once on site. Building commences from the basic level; all building parts like walls, roofs, etc., are made on-site.

Depending on builders’ preferences, here are some differences between prefabricated and precast buildings.

Foundation

The foundational level of a prefabricated and precast building differs. Traditional construction employs a technique whereby a foundation is built on-site utilizing holes in the surface, concrete, and wooden docks. Prefabricated construction, on the other hand, uses pre-constructed parts, which a crane then transfers onto a permanent foundation. Then, they are attached to the ground, usually utilizing steel clasps.

It should be noted that both forms of construction foundations are reliable and safe.

Cost

Regarding price, the prefabricated construction method has an advantage over the precast construction model.

Due to various reasons, traditional construction costs will likely be higher than their prefabricated counterparts. Materials like building parts and other variables like labor time, shortages, climate constraints, and other unforeseen variables also play a role in this.

For prefabricated construction, costs are reduced due to having 90 percent of its manufacturing performed in a controlled factory setting. Several techniques can be applied to minimize spending, such as utilizing essential modules for building parts, circumventing difficult weather conditions, decreasing labor time, and evading problems like labor shortages.

Their Design

The respective designs of both modular and traditional construction techniques are pretty different and unique from each other.

The designs of traditional construction can be altered or changed to the builder’s taste because it operates on a system of constructed on-site parts.

There are some design restrictions in the case of prefabricated construction modules. Nonetheless, its modules are recognized to be highly adaptable and can assume lots of different techniques. Builders can labor with their modular suppliers to determine the design options they want to keep themselves happy with the proposal before construction begins. Modules can also be designed to assume new and modern designs, which is terrific for those with modern taste.

It should also be noted that both traditional and modular construction can adapt to building improvements down the line. Builders can construct modules and standard building parts to match their modern building exterior.

Eco-Friendliness

Regarding the effect these two construction methods have on the environment, the prefabricated building technique is more eco-friendly than the precast method of building.

Because a prefabricated system of building constructs its building parts using mechanized machinery in a well-controlled and safe factory setting. It reduces the negative impact the Construction industry is said to cause on the environment. For the precast method, the environmental effect of starting from scratch and constructing all building parts simultaneously in a less controlled site than its prefabricated counterpart can be a little damaging.
