Identify what must stay live
Map critical services, secure rooms, customer access and the teams that cannot relocate temporarily. Use this to establish realistic phasing.
Agree working boundaries
Discuss noise, dust protection, safe routes, working hours and communication with building management and the project team.
Make handovers explicit
Each phase needs clear completion criteria and a plan for furniture, technology and staff moves. Avoid treating practical completion and readiness to work as the same milestone.
