Measure from a point cloud survey

Load the point cloud of the existing conditions and orient yourself in it, checking the scan covers the areas you need to measure without big shadows or gaps.

Why: A scan with a hole where you need a dimension is worse than no scan, because you only find out at measuring time. Checking coverage first saves a wasted return to site.

Measure the distances, wall and floor areas, room heights and volumes you need directly on the cloud, reading them off the real geometry rather than a drawing.

Why: Existing buildings are never square or plumb the way a drawing pretends. Measuring the as-built reality is what keeps a refurbishment quantity honest and the price behind it safe.

Bring the measured dimensions into the quantity takeoff as the source quantities for the work, keeping the link back to where each one was measured.

Why: A quantity that traces back to a point on the survey is defensible. When someone questions a figure, you can open the cloud and show the measurement it came from.

Price the measured work in the bill, so the survey-based quantities flow straight into a cost without a rekey in between.

Why: Carrying scan measurements through to the bill keeps one unbroken chain from the real building to the price. Every manual copy in that chain is a chance to introduce an error.
