Modular & OSM

Modular and Offsite
Manufacturing (OSM)

Identify, design, fabricate and install modular and OSM solutions

Since our inception in the 1980’s we’ve been delivering OSM and prefabrication solutions. Today, our team tailor cutting-edge modular and offsite manufacturing solutions to specific project needs. Led by our specialist design team and backed by our in-house fabrication facility, our OSM expertise includes the fabrication of bespoke skids, precisely manufactured to seamlessly integrate into larger, complex systems.

We have significant expertise in the production of high-quality, prefabricated pipework, helping to significantly reduce on-site installation time and costs.
