Off-Site Fabrication & Modular Build

Woodhams manufactures and pre-assembles pump skids, process pipework, distribution chambers and modular steelwork in our own workshop, so that time on live water and wastewater sites is spent installing, not building – reducing disruption, site congestion and programme risk.

Off-Site Fabrication for Water and Wastewater Projects

Treatment works are congested, operational and often short of laydown space. Every hour spent building on a live site adds risk: more people near live assets, more work at height, more interfaces with operations and more exposure to weather and programme change. Woodhams moves as much of that work as possible into a controlled workshop environment, then delivers finished, tested assemblies to site ready to install.

What we manufacture off-site

  • Pump skids and packaged pumping assemblies
  • Process pipework spools in carbon and stainless steel
  • Stainless-steel distribution chambers
  • Modular access bridges, walkways and platforms, fitted out with flooring, handrailing and gates
  • Steel structures, support frames and pipe racks
  • Bespoke mechanical components designed around the existing site

Why build off-site

  • Less disruption to live treatment processes and site operations
  • Less site congestion – materials arrive when they are needed, not before
  • Safer installation, with most fit-out done at low level rather than over open tanks and channels
  • Better quality control in a workshop than in the open on a live site
  • Shorter installation windows and greater programme certainty
  • Less waste and lower overall project cost

Off-Site Fabrication in Practice

Our workshop at Woodhams Business Park, Rotherwick, is certified for CE/UKCA fabrication to Execution Class 2 under BS EN 1090, and our in-house design team produces detailed designs to WIMES and fabrication drawings, so every assembly is designed, built and checked by the same team that installs it. Where a project calls for it, we have also set up dedicated local off-site facilities close to site to support just-in-time delivery.

Building off-site doesn’t mean losing flexibility. Pre-assembled components can be held and released to suit changing programme dates, and our project managers keep the client and site teams informed through weekly progress meetings. See our steel fabrication and mechanical and pipework design pages for more on our workshop capability, or the water industry overview for our full MEICA service.

Off-Site Fabrication FAQs

Where is your fabrication workshop?

At Woodhams Business Park, Rotherwick, near Hook in Hampshire – well placed for sites across the South of England. For larger schemes we can set up a local facility near site.

What standards do you fabricate to?

CE/UKCA to Execution Class 2 under BS EN 1090, with design to WIMES and to each water company’s own specifications.

Can you fabricate to someone else’s design?

Yes. We can work to a designer’s issued drawings or take on the design ourselves.

Do you only fabricate, or install as well?

Both. We can supply only, or deliver and install as part of a full package alongside process pipework, pumps and valves and access steelwork.
