Offsite building refers to the planning, the manufacturing, and assembly of building elements at a site that is not their final place of installation. It is a growing trend in the construction industry, where companies are taking the building process to a controlled factory environment and away from the physical site. Here are the benefits of offsite building.
A factory offers a predictable setting, unlike the physical construction site where the contractors will be working on for the first time. At the factory conditions are always the same thus errors are less likely to occur. Variables are eliminated and thus dangerous occurrences that could occur on site are eliminated.
Onsite construction can cause a lot of disruptions to the nearby residents. There is a lot of noise and air pollution caused by the heavy machinery used during constructions. Moreover, the trucks delivering materials to the site may cause traffic causing delays. Construction requires the use of cranes, which could be an eyesore to the residents, besides the construction work could go on for months causing the residents inconvenience for a long time. When these constructions are moved to the factory, these disruptions will not be felt.
In offsite construction, the work is done by prefabrication for modular buildings, this is done repetitively this means that the workers are specialized to work on particular projects. Thus specialization makes the worker master the specifics of a particular project; this reduces the possibility of a worker who is not familiar with the project to assemble the component on-site, which could lead to injuries. The factory can produce consistent quality on a large scale which is virtually impossible on site.
The offsite construction and the onsite schedule run concurrently, as the factory assembles the components, the workers on site are building the core and the structure. Once the products are delivered to the site, they are installed immediately which leads to a lot of time-saving ensuring the project is completed on time.
On-site construction depends on a lot of conditions that change from place to place as well as from time to time. In offsite construction, most of the conditions remain the same. In onsite construction majority of the projects budget is spent on labour and other conditions with a smaller portion being spent on materials, however, with offsite construction, only 30% of the budget is spent on labour with the larger 70% being spent on materials. True, labour costs can fluctuate but being set at 30%, the fluctuations’ impacts are minimized. The cost of offsite construction is more predictable than in on-site construction.
Reduction in material waste
In an onsite construction, materials are delivered to the site where they are cut to fit, most of what remains to go to waste as there is nothing else being made from the same material this is not the case in offsite construction where any extra material is utilized. They use software that calculates where to use extra materials, thus generally speaking at least 85% of all material is utilized.
You get more with offsite construction. All the aspects of construction, quality, price, and speed are all met with offsite construction and still manage to keep the process affordable, predictable, and efficient.
