GeoSLAM BAM Building Scan

Rapid Mobile Scanning for As Built Building Surveys

Harriet Brewitt

Client: Royal London
Architect: Scott Brownrigg
Structural Engineers: Heyne Tillett Steel (HTS)
Contractor: BAM Plant

BAM Plant were commissioned to install the steelwork and concrete slabs to a 5-storey commercial redevelopment in Egham, Surrey (UK). The structure of the building is a composite steel frame with in-situ concrete slabs on a 7.5m x 9m grid.

Part of BAM’s brief was to laser scan the new building elements to check the measurements of the floor slabs. After considering various options, BAM decided that a mobile scanning solution was preferred. They used a GeoSLAM ZEB-REVO surveying system from Opti-cal, GeoSLAM’s UK distributor.

Andy Ewen, BAM’s Manager of Survey and Power tools, explains the choice;

“This was the first time we used this type of scanner and we were able to complete the whole structure in approximately one hour. After completing the scan we were able to segment the point cloud survey to obtain the individual floor areas as required.”

To find out more about the rapid mobile surveying technology that is the ZEB-REVO, you can visit the Opti-cal website and find your nearest office location, or for enquiries outside of the UK, you can email GeoSLAM at info@geoslam.com
