The 10 acre site has a capacity of 450 buses complete with maintenance depot, dedicated service tunnel with deep clean facility, specialist long term vehicle repair centre and regional headquarters. Facilities at the depot include three services lanes with wash, valet and fuel facilities, MOT bays, repair centre with 10 bays, maintenance area with 20 prefabricated pits, accommodation for office staff, drivers and depot employees, and parking areas for the entire fleet. The depot is currently the largest in Britain and will incorporate PV cells on the roof (capable of generating 185,000 Kilowatts Per Hour of electricity per year), intelligent fuel monitoring, rainwater harvesting, intelligent lighting and building management systems. Intersected by the M74, the site obtained by the client took the form of two triangles with a connecting tunnel underneath the motorway. Specialist vehicle tracking and knowledge of the movement of such a facility was key to ensure maximum parking provision with minimum vehicle movement and ‘dead mileage’. The phasing of works during this project was critical to enable the service lane and parking facilities to be operational for the first time during the Glasgow 2014 Commonwealth, six months prior to the intending practical completion date.
