The two-year project will see Shepherd deliver MEP systems for the replacement road bridge’s North and South approach sections, the central cable stayed bridge, its three towers and abutment buildings.

The project comes hot on the heels of a plethora of Scottish contract wins for the firm over the past 12 months, totalling more than £40 million.

Due for completion by the end of 2016 and commissioned by Transport Scotland, the new Queensferry Crossing - set to be the longest three tower cable-stayed bridge in the world - will help to ensure the future of this vital element of Scotland’s transport network.

One of the most technically challenging elements of the project will see Shepherd Engineering Services deliver its largest ever pre-fabrication installation to date; installing and securing 120 prebuilt road deck sections across the Firth of Forth.

In a ground-breaking move, these fully-formed modules will be developed at a specially created off-site manufacturing hub in Rosyth. This represents the first time Shepherd Engineering Services’ pre-fabrication factory, Shepherd PRISM, has ever designed and engineered modules away from its Yorkshire base.

This pioneering move is expected to significantly reduce logistical constraints and costs and ensure the efficient delivery of this key aspect of the major project, which will stand 207 metres above high tide (683ft), equivalent to approximately 22 London buses stacked end-to-end.

Shepherd Engineering Services regional director for Scotland, Colin Walker, said: “The Queensferry Crossing project represents a key facilitator to Scotland’s future economic success, so we are immensely proud to be able to support this major investment in infrastructure.

“The development of our unique off-site Shepherd PRISM pre-fabrication facility illustrates our commitment to innovation and smart thinking. Not only will our team of experts be able to maximise efficiencies by creating the bridge modules off-site, we will significantly contribute to a reduction in the project’s logistical and on-site health and safety risks.”

Shepherd Engineering Services has significantly strengthened its portfolio in Scotland with a string of major contract wins, including a contract from principal contractor Interserve to deliver a full M&E building services installation at the Glasgow Recycling and Renewable Energy Centre, a contract to deliver M&E services from Sir Robert McAlpine at Fife Park, and a further M&E contract with Interserve on The Courtyard by Marriott Hotel, Edinburgh along with an M&E award with Morrison Construction at Clyde Valley High School.

Colin Walker added: “Our portfolio and subsequent standing in Scotland continues to go from strength to strength with the 2014-2015 period our most successful yet.

“We look forward to building upon this solid foundation and continuing to support Scotland’s burgeoning economic future.”
