Prefabrication and Modular Construction have the potential to help the construction industry meet a number of needs like shortage of skilled construction labor, affordable housing, and many more.
FREMONT, CA: Construction owners are exploring new ways to meet the challenges due to the increasing inefficiency of on-site, traditional building methods. Of all, prefabrication and modular construction allow for a more streamlined approach to the building process. In reality, prefabrication is a process in which components are built off-site and then shipped to the construction site for installation. It is a broader category that includes modular construction. Today, prefabrication has advanced significantly, offering high-quality finishes, aesthetic versatility, and design flexibility. It is advantageous over others as the method provides greater control and safety and reduces environmental impact. It speeds up the construction process and thereby, reducing cost.
Modular construction is a method where an entire unit of a building is constructed off-site, unlike panelization, where structural components like roofs, walls, and floor systems are built off-site and delivered to the job site. It requires less amount of on-site construction time as all electrical, plumbing, and other design finishes have already been installed in the facility. Modular construction may hold enormous potential for achieving sustainability goals like reducing material waste, disruption to the building site, and community while promoting safer work conditions.
Building types relying on these construction methods include healthcare facilities, hotels and motels, multifamily and college buildings, and dormitories.
Construction trends like shorter project schedules and labor shortages induce the building professionals to increase the use of the methods mentioned above. Another building technology that enables increased use isbuilding information modeling (BIM). It improves the prefabrication and modular process by being a source to accelerate the design early enough in order to take advantage of these approaches and then offering certainty during the entire process. These tools enable the industry to invest more in the use of multi-trade assemblies and, specifically, volumetric construction.
According to the recently released Prefabrication and Modular Construction 2020 SmartMarket Report by Dodge Data & Analytics, prefabrication and modular construction are providing significant improvements and efficiencies, thereby transforming the industry.
