Multi-storey car park, Manchester Airport
Full design and build contract for the supply, treatment and erection of structural steelwork and metal decking for the steel frame including office building and link bridge.
The proposed development is a multi-storey car park with five levels of parking for approximately 8,500 valet parked cars. It will be used as a drop and go facility and will include an office building, reception, and a footbridge linking into terminal three.
The multi-storey car park off-site and on-site programmes are being completed to a tight schedule, necessitating high production outputs from the Group’s Dalton manufacturing facility and a high erection piece count on site. Overall, 4,100 tonnes of structural steelwork were supplied for the main multi-storey car park, 70 tonnes for the reception building and 110 tonnes for the link bridge into the main terminal building. The car park floors also include metal decking supplied by Severfield with in-situ cast concrete. Approximately 126,000 square metres of metal decking and 165,000 shear studs were provided as part of the erection programme.
A key design challenge faced by the Group’s project team was to overcome the difficulties encountered by the inclusion of a bespoke fire protection system within the scope. This precluded the use of a conventional intumescent paint system and galvanised metal decking. After extensive research, the Group selected metal decking coated with Magnelis, a new metallic steel coating system comprising zinc, aluminium and magnesium which provides superior corrosion protection to galvanising. Due to the harsh environmental conditions, working closely with specialists Sherwin Williams, we opted to use a type of intumescent paint originally developed for the off-shore industry, which satisfied MAG‘s requirements.
