Bam Construction has won a £30m contract to build an operating centre for Network Rail.
The three-storey building in Basingstoke will house a signalling control centre for the Wessex region. It will also include amenities for training, such as track and welding facilities, and office space.
Bam Construction will use building information modelling for the scheme. It will aim for a BREEAM Very Good rating and the building will include combined heat and power facilities. It will also have power supply from two electricity substations so that it can continue to operate in the event of a natural or man-made disaster.
Sister company Bam Nuttall will build a pedestrian bridge over the railway line.
Bam Construction said it would try to recruit local suppliers to the project and aims to work with local schools to involve pupils in the scheme.
A groundbreaking ceremony was held late last month, and the project will finish in November 2014.
