The Real Cost of Refurbishment: Days Closed
In a commercial refurbishment the most expensive item is usually not material but the time the business stays closed. That makes the project as much a scheduling problem as a design one. The right approach is to zone the work so closure is shortened, order long-lead items before site starts, and concentrate noisy and dusty work outside trading hours or into a single intensive window. If closure time is not set as a target at the beginning, the programme stretches on its own.
- Closure duration defined as a target from the start
- Zoning: one part trades while another is under construction
- Long-lead items ordered before site works begin
- Noisy and dusty work concentrated outside trading hours
- Critical path analysis — knowing which task drives the programme
