DOME DEVELOPMENTS: Millennium Dome cladding erection subcontractor Danny's Construction Company will use two sets of moving platforms to fix the PTFE-coated cladding panels supplied by US-based Birdair. Designed specially for the task by High-Point Rendel, the platforms, made up of four radial walkways linked by three circumferential trusses, will be suspended from the Dome's cable net and will rotate as needed during cladding operations. DCCL site manager Michael Miller said use of the platforms would eliminate the type of abseiling operations used to construct the cable net. Full scale cladding operations are due to start next month and be completed late September. The first consignment of Birdair's cladding arrived recently and ground level trials are now in progress on the Greenwich site. Designing the platforms is High-Point Rendel's second involvement in the Dome project. It carried out design checks on the cable net and 12 supporting masts with Hyder Consulting.
