What a corporate move involves
The phrase covers two different jobs. An office move relocates a facility: workstations, conference rooms, filing, copiers, and the network that ties them together. Corporate relocation can also mean moving transferred employees and their households, which are separate shipments with their own estimates and usually their own policy.
Either way, the calendar is set by things other than the mover. Lease end dates, build-out at the new space, and the building's own rules on loading docks, freight elevators, and after-hours access decide the window. A licensed commercial mover works inside that window, usually on a written plan that says what leaves when, in what order, and where it lands at the other end.
Expect a survey before any serious estimate. For a workplace of any size that means a walk-through or a detailed video call, a count of workstations and large pieces, and a look at both buildings' access. An estimate written without one is a guess.
