Manhole Covers Limited in association with Sir Robert McAlpine and Grimshaw Architects helped design a continuous removable steel duct system enabling event organisers to have access to below floor services at ExCel London.
Excel London’s design criteria required covers to withstand forklifts, heavily laden vehicles and emergency vehicles whilst giving quick and lightweight access for user safety.
To achieve this Manhole Covers Limited had specially laser profiled frames produced which then housed further laser profiled solid removable covers.
To prevent lateral movement from heavy traffic fishtail lugs were utilised along the frame edges with covers designed to be inserted within the frames for increased stability.
Over 900 of these bespoke 1220x770mm covers and frames were successfully supplied to the ExCel London project.
