How to Fit Out a Live Office Floor Without Losing a Trading Day

Cat B fit-outs around a trading tenant — what actually works versus what just sounds good in a method statement.

Most contractors quote a tenant-trading fit-out, then ask for two disruptive shutdowns once the programme bites. We do not.

On a recent 12,000 sq ft Cat B in the City we phased the works around the tenant's calendar — pre-agreed weekend windows for anything noisy, out-of-hours M&E reconfiguration, dust screens that actually sealed.

The tenant reported zero downtime against the 6 days of disruption the previous contractor had quoted. That difference paid for our fee three times over.
