Network Rail Mallard House

Spectrum was appointed by main contractor Buckingham Group to deliver the external envelope on a new state-of-the-art facility at Network Rail’s existing Maintenance Delivery Unit in Doncaster.

Almost 600 workers will be based at the £14 million depot, named Mallard House after the famous steam locomotive. The facility includes a modern three-storey building with mess facilities and two floors of office space and a new maintenance storage building. This means teams can work more collaboratively on projects to maintain and improve the railway. It will also help to boost the economy in the town which is famous for its railway history.

Our scope of works included delivery of the complete roofing package which incorporated a standing seam roof to the south, to reflect sunlight minimising heat absorption, and to the north, a green roof to promote increased biodiversity, enabling the building to achieve the required BREEAM certification.

With the office building featuring bespoke facade and roofing finishes, a collaborative approach was required to avoid issues and maintain the tight build programme. From the outset, we worked closely with Buckingham Group and key supply chain partners such as James & Taylor for the terracotta rainscreen tiles, Ash & Lacy for the expanded mesh rainscreen and Gilberts for the louvres. This enabled us to deliver a coordinated project that fully met the client’s expectations.
