Site Owner: Thames Water
The improvement works at Wickham STW in Wickham, Berkshire, were awarded to FSD following the recent expansion of Field Systems Designs to include a mechanical division. FSD were subcontracted to undertake the design, supply, installation, and testing of cabling, instrumentation, trace heating, pumps, macerator, pipework and supports, lifting equipment, walkways, flooring, access and lighting to the site.
Both the mechanical and electrical teams worked closely with the main contractor on site, who undertook the civil works (including ducting), and providing the larger items such as the MCC, kiosk and septic tank. The restricted site footprint meant there was very little space on site for multiple subcontractors at any one time, thus we coordinated our mechanical and electrical works to ensure neither team would be hindered by the others activities as well as maintaining a flexible approach to our installation in terms of scheduling with the client when we could have access to the different areas on site. This was possible as we were also undertaking a number of similar small schemes in the region for the same Client, so we were able to efficiently share resources across multiple sites, focussing on specific sites as needed by our Client.
Part of the electrical works was the upgrading of the site single phase supply, to a new 3 phase power supply. This involved running a temporary supply from the original site supply to allow the works to be undertaken, whilst ensuring the operation of the existing equipment on site was maintained. Once the new MCC had been installed, cabled and tested, we were also able to provide a temporary supply to the cabins for our client once the supply changeover had been undertaken (by others).
Our Client’s designer was also involved in the other schemes running concurrently, so we were able to capitalise on the good working relationship and agree solutions in a timely fashion, allowing us to address them before they become a threat to the programme.
With FSD coordinating and implementing both the electrical installation and the mechanical installation, any issues or queries regarding site were easily addressed, with both divisions assisting each other as necessary – thus minimising delays in obtaining information from site, retrieving measurements or equipment details for closing out design issues. The reduced number of interfaces requiring attention was also a benefit to the project, as the Client needed only to coordinate their civil work and liaise with one point of contact within FSD for the M&E works.
