Explain whether the desk uses a manual adjustment or a powered system. The advertised service covers suitable mechanical furniture assembly. Wiring changes, power-point work and motor or controller repairs are not included simply because they are part of the same workstation.
Separate similar bolts using the instruction labels rather than appearance alone. A fastener that is too long can damage a desktop. Keep spare parts and packing information until the assembly is checked and any supplier shortage has been resolved.
Desk tops can be awkward to turn in a furnished office. Clear space for the parts and explain any narrow doorway or staircase. The intended final position and the route from the delivery area both affect how the job can be organised.
The agreed service covers manufacturer-directed assembly of supported desk frames, tops and supplied furniture hardware. Exclusions: Electrical installation, cable relocation, custom joinery, motor/controller repair.
