For example, a building that would take 12 months if constructed from start to finish using the traditional method can be built by a smart contractor adopting modular construction in between 6 to 7 months (see figure below). The emergence of modular construction as a preferred method comes as no surprise when one looks at its benefits in terms of time and cost. How Modular Construction Benefits Builders Finally, constructing modules in a controlled indoor environment lowers the risk of accidents to construction crew members or damage to building materials, which helps avoid delays lowers the cost of the project. Further, building modules can be disassembled rather than demolished and individual elements can be renovated for later use or can provide the buyer with good buyback value, which reduces the total cost of ownership of the building.

Modular construction demands fewer resources, enabling greater savings that can then be passed on to the buyer. Modules constructed in a factory generate less waste, eliminated material such as wood cut-offs can be used for other buildings, and surplus elements such as wires can potentially be recycled. Modular construction also benefits customers by being more cost-effective than traditional construction.

Moreover, construction delays due to undesirable weather and other external factors are essentially eliminated as the modules are built in a factory environment and can be assembled when conditions are favorable for on-site work, all of which assist in amplifying the efficiency of time and resources used. Since the construction of the structure is done at the same time as site work, it allows the project to be completed between 30% to 50% quicker than traditional construction. The primary advantage of modular construction in a new design is the shortened construction schedule for the customer. There are many benefits offered by modular construction, which range from savings in spend, time, and energy expenditure to greater quality of the final product, as the modules are constructed under controlled plant conditions, ensuring a lower likelihood of unforeseen errors and mishaps. These factory-produced modules are built using the same design and materials and follow the same codes and standards as a traditional building would but can be put together in half the time. Modular construction is a process where large, pre-engineered units - called modules - are built off-site and are then assembled on-site.
