Work for client Extra Motorway Services Group will start later this month between junctions 9 and 10 on the site previously known as New Barn Farm.

Birse is currently building motorway sliproads to the site under a contract worth £19m.

The service station will feature a 4306 square metre ‘amenity building’ to provide retail and food outlet units, a 75-bedroom hotel with associated courtyard with environmental lake areas, approximately 900 spaces for car, caravan, coach and disabled parking, as well as 72 space HGV parking and associated roads, services and landscaping.

The service station is scheduled to open during the summer of 2012.

BAM’s Construction Director, Bob Sanders said: “This is a major transport development in a significant location. BAM is extremely pleased to have been chosen by Extra in this single stage tender at a time of strong market competition, and we look forward greatly to forming a strong partnership to deliver facilities that will greatly benefit the lives of Britain’s busy travellers.”

Andrew Long, the Chief Executive of Extra Motorway Service Area Group, said: “Extra is pleased to be working with BAM as one of the main contractors for this substantial development.

“Extra is investing approximately £77m in the overall project and we are very pleased to now see this come to fruition. We look forward to the Summer 2012 opening date.”

A filling station contract on the site is being tendered separately.

Devereux Architects are lead designers for the development with Sawyer and Fisher acting as quantity surveyors.

BAM Design is currently designing the Hotel Building. BAM Services Engineering provides structural engineering and mechanical and electrical services to parts of the project.

Construction manager on the job will be Antony Nagle who led the team recently on the new wing for the Ashmolean Museum in Oxfordshire.
