← Project registerPedestrian bridge beams over a creek, Wide Bay
Two 2,600 kg beams set across a protected creek where no crane pad could be built on either bank.
01
The constraint
Both banks were vegetated riparian zone with no permissible crane platform.
A temporary causeway needed environmental approval and would have been removed weeks later.
Beam tolerance at the abutments was 15 mm.
