Multi-purpose riser
Offsite residential construction, Glossary of terms, published by Buildoffsite in 2018, defines a multi-purpose riser as a: ‘Multiple service vertical distribution module, constructed from primed or galvanised mild steel and incorporating appropriate building services that may be lagged (insulated). These modules can be connected offsite, but are often transported in 7.5 m lengths to avoid transportation problems. Modules can carry combined mechanical and electrical services but most manufacturers specialise in one or the other. The majority of the electrical risers are manufactured using a mesh or ladder system to allow easy distribution at floor levels in various directions. These systems are often bespoke in design and while the base structure may offer a level of standardisation the dimensions and carrying capacity will vary between projects.’
