Benefits of Modular Construction


The factory-controlled process generates less waste, creates fewer site disturbances and allows for tighter construction.


Construction of modular buildings occurs simultaneously with site work, allowing projects to be completed in half the time of traditional construction.


Modular buildings are built with the same materials and to the same building codes and architectural specifications as traditional construction. Once assembled, they are virtually indistinguishable from their site-built counterparts.


Efficiently finishing your project saves you both time and money, helping you earn a faster return on your capital.

What is Modular Construction?

Modular construction is a process in which a building is constructed off-site, under controlled plant conditions, using the same materials and designs as conventionally built facilities – but in about half the time. Buildings are produced in “modules” that when put together on site, reflect the identical design intent and specifications of the most sophisticated site-built facility – without compromise.
