The UK arm of German engineering and service group Bilfinger has won a “multi-million pound” contract with Aggregate Industries to design, supply, and install new electrical infrastructure at the Bardon Hill quarry extension project in Leicestershire.

The deal forms part of a significant scheme at the site, which also includes installation of a new primary crusher and 4 km of overland conveyors. The extension quarry will be operational in the September quarter of 2019, supplying over 4 Mt/y of aggregates to the UK construction industry.

Bilfinger will design, supply and install the electrical works required to deliver the extension project, which will include 12,000 m of high voltage, low voltage and fibre-optic cabling, together with five new modular substations and transformers. PLC systems will be delivered for monitoring and control, ensuring all systems can run effectively and efficiently. Other site infrastructure will include fire, CCTV, voice, data, and security systems.

Bilfinger said the delivery team will have a peak workforce of approximately 35 personnel.

Bardon Hill is one of the UK’s largest quarries and has supplied the aggregate materials used to build London’s Olympic Park, Wembley Stadium, St Pancras train station and the M1 motorway.

Dave Pickles, Managing Director for Engineering and Technology at Bilfinger UK, said: “Given the scale and complexity of the quarry, an integrated electrical system powered by automation technology will play a critical role in completing the project. Our extensive experience in electrical engineering, together with our range of automated solutions, means we are well placed to deliver a scheme of this significance and scale.”
