Access Steelwork, Walkways & Pipe Supports

Woodhams designs, fabricates and installs galvanised access steelwork, walkways, bridges, platforms and pipe supports for live water and wastewater treatment works – built in our own workshop to WIMES 9.02 and BS EN 1090 Execution Class 2, then installed with the minimum of time over open channels.

Access Steelwork for Water and Wastewater Treatment Works

Safe, permanent access is a requirement on every treatment site: operators need to reach tanks, channels, screens, pumps and valves for inspection, sampling and maintenance without working over open water or at height. Woodhams fabricates and installs the steelwork that provides that access, together with the support steelwork that carries process pipework – as part of a wider MEICA package or as a stand-alone steelwork package for a Tier 1 contractor or water company.

Walkways, bridges and platforms

  • Modular access bridges and walkways spanning tanks and outlet channels
  • Access platforms, stair towers, ladders, landings and self-closing safety gates
  • Open-mesh flooring and mesh-infill handrailing
  • Steelwork substructures supporting new process equipment inside existing tanks

Every structure is designed for the operational and maintenance access the site actually needs, and detailed to absorb the tolerances of existing concrete and pipework.

Pipe supports and pipe racks

  • Bespoke pipe supports, brackets and hangers
  • Elevated pipe racks for high-level process pipework
  • Support frames for pump skids, distribution chambers and process equipment

Because we install the pipework as well, pipe routes, supports and access are coordinated before anything is fabricated.

Specification and compliance

  • Designed to WIMES 9.02 for permanent access fabrications, including client-specific amendments such as Wessex Water’s DS 220 access and protection requirements
  • Fabricated and erected to Execution Class 2 in accordance with BS EN 1090 (CE/UKCA marked)
  • Hot-dip galvanised to BS EN ISO 1461 for long-term durability in wastewater environments
  • Structural grades S275 and S355
  • Fabrication drawings from our in-house design team where required

Recent Access Steelwork Projects

Everything is fabricated at our own facility at Woodhams Business Park, Rotherwick, which gives us full control over quality, tolerances and programme. Structures are built as modular sections, galvanised, then assembled and fitted out with flooring, handrailing and gates in the site laydown area before being craned into position – so most of the work happens safely at low level rather than over open tanks and channels.

On a live works that means fewer lifts, less time over water and installations measured in days rather than weeks. See our Fabrication pages for platforms and mezzanine floors and handrails and balustrades outside the water sector, or the water industry overview for our full range of MEICA services.

Access Steelwork & Walkway FAQs

Do you design the steelwork as well as fabricate it?

Yes. Our in-house design team produces fabrication drawings to the client’s standards and WIMES 9.02, or we can work to a designer’s issued drawings.

Can you install over live tanks and channels?

Yes. We plan lifts and sequencing so that most fit-out happens at low level and time over water is kept to a minimum – the 60 m Holdenhurst bridge went in in one day.

What finish do you use?

Hot-dip galvanising to BS EN ISO 1461 as standard for wastewater environments; stainless steel or painted finishes where the specification calls for them.

Do you supply steelwork on its own, without installation?

Yes – supply-only, supply-and-install, or as part of a full MEICA package alongside process pipework, pumps and valves.
