Midland Survey are experts in surveying complex and difficult to access spaces where there is limited or no GPS, but Oriel College with its labyrinthine network of historic buildings threw up a particular set of challenges.
Oriel College, part of the prestigious University of Oxford is nearly 700 years old, with around 200 rooms across five floors. Including an ‘island site’ accessible only via a tunnel. The structure has been extended over the years and no accurate floor plans or elevation drawings exist. The college is occupied 24/7 and opportunities to accurately scan with minimal disruptions are rare.
David Johnson, Director, Midland Survey said, “Due to the lack of GPS coverage in the tunnel the only option was to use a ZEB-REVO”. Which they obtained from Opti-cal Survey Equipment.
“The unusual shape of the building, with its unconventional layout and complex network of rooms, meant it was too difficult and time-consuming to survey with traditional static scanning methods. We needed a lightweight, mobile tool that works well in enclosed environments. Using the ZEB-REVO around 200 rooms were scanned, amounting to 12,00m². Across 5 days, 12 individual rapid ZEB-REVO scans were completed each taking just 30 minutes. The entire project was completed in around half of the, total time that would have been required using static equipment
