A reliable measured building survey price needs a defined brief. Compare coverage, access, accuracy, control, deliverables and programme before comparing the headline fee.
A complete fee includes preparation, access planning, capture, control, processing, drawing or model production and quality checks.
Coverage, irregular geometry, occupied spaces, restricted hours and the agreed deliverables change the workload; floor area alone does not define a fee.
Avoid repeat work by defining intended use, marked coverage, accuracy, control and likely downstream outputs before coordinating access.
