Contractor -Sir Robert McAlpine
The challenge was to provide mast climber platform access to a new build residential block being erected from a podium on one of the busiest junctions in Bristol. The access was required to follow the building as it was progressively erected. The MCWP was to facilitate access as the concrete structure completes, and for the first, second and final fix of the cladding each phase increasing the circumference of this egg shaped building.
- The building was egg shaped on plan.
- All the equipment had to carried to podium level.
- Vary limited storage at podium level - shared with Joiners' and steel fixers and others.
- Four of the positions could not be erected from podium.
- The four podium positions had to be delivered and erected in out of hours working in road closures.
- Profile of the building would change three times during the construction.
- Delivery constraints due to bus lanes and pedestrian traffic - busiest corner in Bristol.
- The design, engineering and manufacture of the front extensions were particularly exact to cope with the curve of the building.
- The front extensions on the platforms were designed to be altered 3 times as the profile of the building extended out as each stage was completed.
- Scaffold cantilevers were designed and erected to carry 4 of the mast climber platforms.
- PHD Hoists and Masts worked very closely with the client to programme the work.
- Due to the restricted access and limited storage out of hours working and military precision was required to co-ordinate the deliveries – road closures and crane set up.
- Despite adverse weather, late handover and many other challenges the squads working on this project are to be complimented on achieving their target each shift.
