BIM gets people and information working together effectively and efficiently.
“Since the introduction of BIM at Gade I have been able to carry out twice as many weld inspections because I don’t need to visit the site office as frequently.” – Shakeel Khan, NDT Weld Inspector, Mistras Group Ltd
Gade Valley Viaduct is a multi-span composite viaduct carrying the M25 between Junctions 20 and 21. The 450m long viaduct is composed of twin decks, each formed from four open topped steel box girders with an in-situ cast concrete slab.
Due to a lack of fatigue strength in the bottom flange over 50,000 strengthening components are required, each with their individual quality record. This includes:
- 750 weld dressings
- 2500 strengthening plates
- 48000 bolts
- 1000 paint sections
