Problem/Challenge

The requirements of the project demanded the use of non-conductive, lightweight flooring and structures to overcome the intrinsic operational dangers in a high voltage substation environment.

Another challenging factor within the project was that our scope of works was significantly increased within the originally agreed installation schedule.

Solution

To surmount the high voltage operational dangers, the lead contractor Balfour Beatty contracted Relinea to design, supply and install GRP (glass reinforced plastic): open mesh floor grating, structural support beams, handrail and an access platform. GRP is non-conductive thus avoiding earthing issues and being a 1/3 of the weight of steel mitigates many of the health and safety issues resulting from on-going manual handling.

Considering that the scope of the original project had increased, whilst the installation timeframe remained constant, Relinea nevertheless proficiently delivered the project on time, on budget and to a very high standard. This was to the complete satisfaction of the principal contractor.

The lead contractor Balfour Beatty was extremely impressed with Relinea’s Project Management skills within the substation upgrade scheme, whilst efficiently adhering to the rigorous onsite Health and Safety procedures.
