Verifying 40,000m² of warehouse flooring with billions of measurement points.
Plowman Craven Australia delivered high-precision floor flatness verification across approximately 40,000m² of a major distribution centre in Eastern Creek, New South Wales.
Using high-definition laser scanning, precise survey control and advanced point cloud analysis, the team captured the entire floor within a one-week programme. The results confirmed that the finished floor exceeded its specified TR34 FM2 requirement by achieving FM1 performance.
Verifying floor performance across a vast operational area
The approximately 40,000m² warehouse floor needed to demonstrate compliance with TR34 4th Edition FM2 requirements ahead of project handover.
Verification had to be completed within one week while construction activity and multiple subcontractors remained operational across the site. Traditional sampling methods would only assess selected areas, potentially leaving variations undetected. The client therefore needed comprehensive floor coverage, reliable analysis and clear evidence of performance without disrupting the wider construction programme.
Combining high-definition scanning with precise survey control
Plowman Craven Australia used a Leica P40 laser scanner to capture billions of measurement points across the entire warehouse floor, creating a highly detailed digital representation of the finished surface.
A precise survey control network was established using a Leica total station and more than 100 targets tied to the building datum. The point cloud was then analysed against the required tolerances, with the results presented as clear, colour-coded heat maps. This gave the project team an accessible overview of floor performance while allowing the survey to be completed alongside ongoing construction activity.
Billions of measurement points provided a comprehensive understanding of performance across approximately 40,000m².
Detailed point cloud analysis provided clear evidence of how the completed floor performed against TR34 requirements.
Potential variations could be identified before handover, reducing the risk of costly corrective work later.
Colour-coded heat maps transformed complex survey data into a clear visual format for the construction team.
The survey was completed within one week while construction activity continued across the site.
Verification confirmed that the floor could support the demanding requirements of a major modern distribution centre.
The completed survey confirmed that the warehouse floor not only met its specified TR34 FM2 requirement but achieved the higher FM1 performance classification.
By combining high-definition laser scanning, precise survey control and advanced point cloud analysis, Plowman Craven Australia provided comprehensive evidence of floor performance across approximately 40,000m². This gave the project team greater certainty ahead of handover, reduced remediation risk and confirmed that the facility could support its intended operational demands.
