Contractor - John Sisk and Son Limited

Both Bovis Construction and John Sisk Contractors were building adjacent to each other. PHD were called upon to surmount this challenge where 2 adjoining builds clashed.

Challanges

  • Bovis Construction were building adjacent to John Sisk Contractors Hotel Project
  • The block they were building was 12 # floors higher and would not complete before the Hotel opened.
  • Access would have to be over the hotel and there was a problem over air rights.
  • The incumbent scaffold contractor proposed a Beam Bridge system which blew the budget and could not be completed in the time available.

Solution: 2 platforms on 1 mast tower.

PHD designed a truss out cantilever system onto which they sat their 3,000Kg capacity mast climber and mounted 2 separate platforms on one mast.
This allowed different trades to work on the same elevation at the same time.This meant the client could catch up on programme , avoid penalties and
save against the more expensive and time consuming beam bridge solution.
