Starting point.

An interim payment application is submitted every month, and every item needs evidence. Previously this meant plans, phone photos and on-site measurements, often weeks after the work was completed. Work hidden behind suspended ceilings or screed could hardly be documented afterwards.

Use of Plonda.

Once a week, a site manager walks through each site with the 360° camera. Plonda records the condition and date, builds a 3D model in which areas can be measured, and links quantities to the bill-of-quantities items.

Result.

Measurements for a billing stage are taken at the desk instead of on site. Quantity discrepancies are found before approval rather than at the final invoice. And when a variation is disputed, the walkthrough from that day provides the evidence.

José Sá Machado
“With Plonda I go back in the walkthrough to the day the work was carried out and measure it. That ends most discussions before they begin.”
