KEY RISKS/CHALLENGES

Preventing the bridge from collapsing. A designed scaffold was the preferred option rather than a Centering System which saved the client a considerable amount of money
Liaison with the public, who despite extensive signage, expected access through the construction site
Pollution prevention to a main river
Having sufficient resources available, in particular stone masons, to install 900m² of walling and buttresses
Extensive discussions with the EA to agree their requirements and obtain permit to work within the river

COLLABORATION AND VALUE ADDED

The drainage system below the approach road was redesigned by ourselves which resulted in a saving for the client
Masonry walls carried out to the highest possible standard by our own directly employed masons, which gives us certainty on the quality of the finished product
