Laser Scanning/Survey of University of Dubuque North-South Campus Corridor

WHKS utilized 3D laser scanning technology to conduct a topographic survey of the University of Dubuque central campus (north-south corridor).

3D laser scanning shines a reflectorless laser line over a surface to collect three-dimensional data. The surface data is captured by a camera sensor that is mounted in the laser scanner that records accurate 3D points in space. A 3D laser scanner can take multiple measurements in rapid succession, allowing a surveyor to capture dense point clouds in a matter of minutes. The rapid method for obtaining survey measurements allows the surveyor to work with minimal disruption and often, without the need for multiple site visits.

The work included the location of the existing underground utilities and features on the visible grade. WHKS provided existing floor elevations for buildings and survey points to complete a one-foot contour map of the site. Horizontal and vertical control monuments were set for current and future use on the campus.

The project was on an accelerated schedule to meet the needs of a planning project for the University.
