Offsite construction, or pre-fabrication, is the production and assembly of building components away from the project site. After manufacturing, the assembled parts are transported onsite hence more sustainability in construction methods. The benefits of offsite construction go beyond the factory environment; thus, the best alternative for meeting construction targets and skill shortages.

Saving more time on site
Designing and manufacturing building materials offsite can result in at least 20% fewer onsite days. Offsite construction uses various materials, scales, and systems, innovative manufacturing and fabrication, and modern assembling techniques to ensure faster project delivery.
For instance, the manufacturers fabricate timber products and floor cassettes, lift them into position, and secure them onsite. Offsite construction means that work in a factory can be scheduled to start at the same time as the site preparation resulting in faster build times. Manufacturers also utilize advanced software to identify production bottlenecks and address them to meet site targets.
No storage is required onsite.
With offsite construction, no storage is required onsite, freeing up the much-needed space, which also enhances health and safety. In most cases, contractors coordinate offsite production and site preparation, ensuring the building products’ delivery when needed.
The manufacturers usually fit the construction materials with lifting slings, making it easier for workers to crane them directly from the lorry to the building. Reliable offsite manufacturers work with clients to schedule deliveries in advance to ensure efficiency.
Reduction of accident risks
One of the reasons why offsite construction is rapidly growing in popularity is that it reduces accident risks on construction sites. One thing about traditional construction methods is that workers face safety risks due to working in poor visibility conditions, weather elements, and high heights.
With offsite construction, manufacturers take the work into a controlled environment away from the muddy sites and environments with unpredictable weather patterns. That results in windproof and watertight builds ensuring a high-quality build within shorter timelines.
Reduction of onsite labor
Most of the work for offsite construction takes place in the factory since the materials are delivered on site ready for the build. That reduces the onsite labor needed, which translates to more cost savings. For instance, providing prefabricated spandrel panels eliminates blockwork at party walls and roofs during onsite construction.
Reduction of waste
Offsite construction has plenty of environmental benefits, including reducing waste onsite. Cleaner manufacturing allows the recycling of unused materials resulting in less waste. For instance, building materials leftovers for previous projects are kept at the factory, and manufacturers can reuse them for other projects rather than keeping them onsite. The significant waste reduction also makes offsite construction suitable for controlled environments like schools, hospitals, and other facilities where safety is more needed.
Today, there is an increasing demand for housing coupled with shortfalls in sustainable housing. Therefore contractors are exploring new ways to speed up building processes and deliver projects faster, which explains why offsite construction is popular.
