The main contractor needed one supplier for every external opening and both entrance lobbies, working to the site programme. Every flat was weathertight on the programme date.

Each floor was surveyed from its structural openings, then fitted, sealed and signed off before the next was released, so the following trades could start in sequence. One schedule covered the whole block, and one crew stayed on site throughout.

The work
