BSRIA launches Offsite Construction for Building Services topic guide
BSRIA has launched a free-to-download topic guide entitled ‘Offsite Construction for Building Services’. The ‘at a glance publication’ aims to give readers a glimpse of the subject and suggests further reading.
Offsite construction, sometimes also referred to as ‘offsite manufacture’, ‘pre-fabrication’ or ‘modular construction’, is a general term for making parts of a building away from the construction site, in a purpose-built facility, before transporting them and installing them in their final location. It has the potential to make things on site much easier.
Mechanical and electrical systems
The guide highlights offsite construction for services distribution, namely: vertical services risers; larger assemblies; horizontal distribution; offsite construction for packaged rooms – and inside or outside? Also included is whether offsite construction is right for the project in hand.
 Author comments
“As with any technology or process, the use of offsite construction needs to be considered carefully to get the best from it. Working in a controlled, purpose-made environment can increase productivity, with no distractions from other construction site activities or issues.
“The controlled environment enables quality to be improved – the right conditions can be provided for the task and quality control procedures followed – rather than the general conditions of the construction site.
 A few watchpoints
- Consider early on if offsite construction techniques are to be used on the project.
- When considering offsite construction, make sure that the designers know – it may affect the design solutions that are put forward.
- There are different scales of offsite construction, from widespread services distribution to local applications such as packaged plant rooms, see what suits the project.
