The single biggest fear for facilities managers commissioning a relocation is the same: how disruptive is this going to be? Done well, it's barely noticeable.
Phasing
Most rooms have natural phases. Half the bays move on Saturday; the other half on Sunday. The user team always has working storage.
Out-of-hours scheduling
We work nights and weekends as standard for occupied buildings. Surcharge is modest compared to lost productivity during the day.
Dust control
Track lifting can release decades of fine dust. We use HEPA vacuums and ground sheets to keep the surrounding area clean.
Communication
A single named project manager from start to finish. One number to call. One email thread. No bouncing between offices.
