Eon Connecting Energies had been contracted by South Staffordshire Water (SSW) to design and build anew Combined Heat & Power Plant. The plant houses a Rolls Royce, Bergen 5.6MW Gas Powered Engine that replaces the existing diesel generators at South Staffordshire water treatment works currently in Hampton-Loade. The engine provides the base electrical load for the site with exhaust and engine heat being used to provide hot water to the site.

The Project was a full design and build managed by Eon in conjunction with Rolls Royce Bergen Engines. When Legacy Developments started working with Eon and SSW contracts had just been signed between them ready to start on site. As site clearance began, several ground issues became apparent which led to a four and a half month delay in final civil construction designs being released to the chosen construction contractors Hawkins Construction Page 2 of 4(Northern) Limited who were appointed Principal Contractor. By working closely with Hawkins and the appointed Principal Designers the main base to land the engine on was only 2 weeks later than the original planned date, despite the significant delay in civil design release. We gained 4 weeks on programme by engineering form work for the 72 engine pockets, rather than building them out of timer.

The proposed building location was extremely restrictive which meant continuously changing design and building methodology. We managed to achieve all milestones set by the client and continue to provide assistance and services to Eon after practical completion.
