A prominent Danish surveying consultancy won a bid to scan thousands of housing flats, but realized traditional scanning workflows would involve too much time per flat. They chose the Trimble X7 for its automated cloud registration, speeding up not only field acquisition time, but also nearly eliminating office processing time. The resultant 3D models have reduced tenant turnover times for the client, saving many hours and multiple visits for site evaluations and measurements. overview Location COPENHAGEN, DENMARK TRANSFORMING THE WAY THE WORLD WORKS TRANSFORMING THE WAY THE WORLD WORKS Boligforeningen AAB is a non-profit that administers nearly 20,000 homes and flats in the Greater Copenhagen area, managing and leasing these to achieve sustainability and affordable-housing goals. AAB issued an EU tender to scan thousands of these units to streamline the process of tenant turnovers. With 3D models of units, estimating costs for unit refurbishment prior to new tenancy would be reduced. LE34, a prominent multidisciplinary Danish surveying consultancy, sought to bid on the project but realized that conventional scanning workflows might not provide a competitive edge to win the tender. They were looking to automate the processes. LE34's Engineering Surveying Director Anders Nygaard Møller was intrigued by a recent demonstration of a new 3D laser scanner, the Trimble X7, and worked with Trimble distributor Geoteam A/S to acquire their first X7 and get up to speed on operations. "It was fast enough—500,000 points per second—but it was the automated cloud-to-cloud registration in the field and on the tablet that stood out. Results looked to be as good as what we could do registering the point clouds in the office," said Møller. The client, AAB, required 3D models in Revit of each type of flat as well as the offices, shops, basements and stairwells in each housing block. With a 3D model, AAB can estimate the quantities of painting, carpet, piping, etc., that need to be replaced or repaired before the next tenant moves in. With one site visit, AAB and the departing tenant can view and measure the 3D model, calculate quantities, send these to the contractors, and determine how much of their deposit they get back. LE34's Chartered Surveyor Richard Lindquist Capion said, "Our job is to scan the flats, merge the point clouds, perform QA & QC per the client's specifications, and export the clouds for each flat into Autodesk ReCap for Revit model creation."
