Las Vegas, NV (November 14, 2006) – The Surveying and Geomatics group at Stantec’s Las Vegas office was recently awarded a project at McCarran International Airport to assist the customer, Bombardier, in the construction of a people mover that will eventually connect the D concourse to the new T3 terminal via an approximately 1,100-foot long underground tunnel.
"The Las Vegas Survey Group is very excited about participating in this project with Bombardier,” says Will Wheeler, Office Leader for Stantec in Las Vegas. “In addition to expanding our service history at McCarran Airport, the project provides our first opportunity to utilize a 3D Laser Scan system."
In order to meet the tight one-month schedule, surveyors at Stantec will utilize the latest in laser geomatics, a much faster process than more conventional methods. The laser scan will produce a three-dimensional map of the core as-built tunnel while also recording necessary data on existing drainage conditions and other pertinent information. In a matter of minutes, the laser beam will capture images at 16 different points on the full 360-degree radius inside the tunnel at every 2.5-foot interval. For the entire existing 850-foot length, this equates to roughly 5,400 images. This new technology will allow the task to be completed in as little as three days, rather than the estimated six weeks it would take otherwise.
“The post processing of the collected data will also incorporate new technology,” explains Darrin Gassmann, project manager for Stantec. “The ‘point cloud’ structure of laser scans is flexible enough to format directly into the more common autocad format. The technicians can then process line based data in a 3D format to provide the client with high quality exhibits and digital files for their design and information needs.”
Other applications of this technology will be considered for future use on the project. It will provide an opportunity for the accurate, real time capture of as-built data while streamlining the in-process verification of tolerances when Bombardier pours the concrete for the trains’ running pads and installs the steel guidebeam and other equipment along the guideway.
