The works undertaken at Meandah proved a challenge due to the confined work areas surrounded by 110,000 volt live subyard which the works took place in.
What we did
- New blast walls
- New concrete foundations
- Fire doors
- Demolition works
- Lightning foundations / rag bolts
- Sprayed driveways - 2 coat seal
As the Invert Levels of buried services were to be located below the high tide mark, this made the work more challenging due to the amount of water that would be penetrating the works area while digging and prepping foundations and trenches. In this instance, dewatering around the works area was undertaken, while being aided by working during low tide.
Another challenging and 'safety critical' working environment was to demolish the existing transfer compound with a blast wall of 4.8m whilst a live transformer was still in use on the other side of the wall. Scaffold systems were used and additional protection and hoardings were installed between the live transformer and the blast wall so that so that demolition works could progress safely.
