Offsite is Simplifying Construction
End users expect higher levels of sustainability and building performance. Clients expect buildings to be completed to shorter timescales within tighter budgets.
Traditional, linear building methods have consistently been found wanting in meeting these growing demands over recent years and projecting forward they are more likely to get worse rather than improve.
Productivity remains low compared to other sectors such as manufacturing; build times are uncertain (only 40% of projects are completed on time); and the growing skills crisis can only increase costs and uncertainties. Keeping track of projects is also hard – live project data is elusive due to multi-tiered contracts and isolated systems.
Offsite construction overcomes these issues to deliver simpler, faster and more sustainable construction:
Productivity is improved: the main building elements are fabricated in a controlled manufacturing environment and are easy to install.
Build times are reliable: ‘buildability’ is designed-in from the outset. There are fewer onsite processes and trade dependencies, and weather conditions are no longer an issue.
There is less need for traditional skills: most of the structure is prefabricated and building fit out is simplified through the design.
Data transparency is improved: designers and multi-tiered contractors can be involved from the outset with access to a common design and project management platform.
The result: cost effective, more adaptable, more energy efficient structures, built to a predictable, shorter timescale. Additionally, waste is reduced, sustainability is improved and whole life asset costs minimised.
Forms of Offsite
‘Offsite’ covers different construction methods including:
- Component sub-assembly; where smaller scale items such as light fittings, doors or windows are assembled offsite.
- Non-volumetric preassembly; which includes panel systems (such as Innovaré i-SIP), cladding panels and above-ceiling service units.
- Volumetric preassembly; that creates usable spaces offsite for installation in or onto buildings.
- Complete buildings; that either form, or fit together to form, the whole building structure and are often delivered fully fitted out.
Non-volumetric preassembly offers complete design flexibility with simplicity of transportation and assembly. It offers the best blend between flexibility, scalability and cost efficiency. Innovaré is the only manufacturer in the UK to offer complete non-volumetric SIP delivery.
