Construction Tech Review | Thursday, October 31, 2019
Prefabrication has been appreciated for its numerous benefits, such as superior quality outcomes, cost-effectiveness, fast and better site security, reduced environmental impact, and lessening labor shortage problems.
FREMONT, CA: The much-used terms in the construction industry are prefabrication, modular construction, and offsite construction, which are used interchangeably, with subtle differences. These are the factors of the industrialization of construction, where manufacturing techniques are being used to enhance the construction process.
Prefabrication is all about making a building or its components in a controlled environment. It can be considered as a manufacturing process that takes place at a dedicated facility, in which different materials are accumulated to form a part of the final installation. It includes a single trade, such as electrical, and once it is completed, the components are moved to the building site for assembly.

Offsite construction can be considered closely related but is still slightly more general. It connects to the broad aspect of planning, fabrication, design, and assembly of building fundamentals in a location, which stands away from the final building site. Nevertheless, it does not indicate how the components that are produced can come together. When it comes to the difference of offsite construction and prefabrication, the offsite is the location and prefabrication is the method.
Prefabrication is sometimes mixed up with modularization. It is equal when it is about the process of constructing a structure in a factory before gathering it on the job site. On the other hand, modularization refers to the preconstruction of an entire system where the modules are large box-like structures, which make up a whole formation when they are assembled on site.
There are several construction safety benefits of prefabrication:
Controlled Setting:
It is a fact that construction sites are chaotic environments that keep changing, developing, and are subject to the conditions around. Prefabrication helps in putting the worker into a controlled environment, where several risks of traditional sites can be easily avoided. Additionally, offsite construction nearly eliminates the risks that are created by extreme weather conditions. Because of it, there tend to be no slippery platforms from rain or snow, reducing the on slips and falls, or open electrical lines to moisture that can eliminate chances of electrocution.
Reduced Waste:
The circumstances of a construction site show that the sites are laid out and have restricted alternates in dense urban areas. Offsite construction allows a better material flow for the complete project by taking out the material from the job site. The minimum amount of materials that are stored on-site reduces clutter and wastes. The step can lead to a cleaner, organized, healthier, and safer project site.
On-site Workers as Required:
Less number of workers on-site can eliminate the risk of more workers getting hurt or injured in an accident or otherwise involved in a safety incident. By reducing the number of workers on-site, organizations can diminish the potential chances for something that can go wrong. The workers who work with the prefabricated pieces tend to be the most knowledgeable, enabling sites to utilize the expertise of expert workers while lessening the requirement for workers with barely any training in safety procedures. Less crowded job sites and lesser possibilities of challenges can, without a doubt, bring a better working environment.
Safer Preparation:
Offsite construction brings safer installation procedures with improved installation schedules, narrowing down the need for any rushed work or swarming workspaces. Trade stacking, which is considered to be having multiple trades working in the same area, can be avoided once and for all while keeping a swift project pace.
