Traditional onsite construction is, of course, the face of the construction industry and will continue to be the dominant way of constructing building and infrastructure. However, with so many changes happening around us, offsite buildings have not probably shown that much development.
Offsite construction of both prefabricated and modular structures is getting some tractions. Construction of houses, hospitals, commercial buildings, educational buildings all are experiencing offsite construction.
With the increasing construction activities, in the coming years, major parts of the construction will consist of offsite construction. Currently, Asia Pacific leads the world in prefabrication construction.
Similarly, the adoption rate of prefabricated building structures is also high in Europe and North America. On the other hand, in the Middle East and Africa, the adoption rate is low.
The high and low adoption rates of prefabricated structures in different regions can also be linked to labour shortages and environmental concerns.
In East Asia, North America, and Europe, there is a growing shortage of labour due to the rising ageing population. So, the prefabrication trend is set to rise, which would require less labour force.
On average, if an onsite construction project requires 6-10 months for completion, then it can be reduced to just a few weeks through prefabrication/offsite construction and modular construction.
Some major companies are using prefabricated structures like Google, Marriot and Starbucks.
