Hygienic zoning and the building fabric
The Challenge
Changes to clean and less-clean zones can affect floors, drains, walls, doors and air systems together. A late hygiene requirement can make completed work unsuitable and create disputes across trade packages.
Our approach
We follow the hygiene team's revised requirement across floors, drainage, partitions and air systems. Those changes need to be costed together: a new zone boundary can affect much more than the wall marking it. The account also identifies work already completed and checks whether the original specification was met, keeping changed requirements distinct from rectification.
