tunnel will require a greater vertical clearance. To identify the areas needing additional clearance and obtain this specific data, a detailed survey was required, using nontraditional methods. During a five-day period on site, Dewberry surveyors supervised and assisted Optira, Inc. with scanning the tunnel and establishing coordinate values for over 190 targets. Dewberry, as a subconsultant to Jacobs Engineering, suggested using digital scanning as a means to provide more accurate results. Dewberry partnered again with Optira, Inc., to perform a terrestrial LiDAR scan of the 4,500-linear-foot Bergen Tunnel. The data collected from the scan is being used to identify areas in the tunnel where the crown of the tunnel will require removal of rock and/or brick liners. Dewberry is also producing a detailed 3D model of the tunnel’s existing conditions and providing the client and owner with an historical record of this nearly 150-year-old structure. At the Virginia Railway Express station in Woodbridge, Virginia, Dewberry performed an experimental test using an InteliSum digital surveying system. From the captured data, Dewberry surveyors and engineers were able to develop an “intelligent” image of a pedestrian walkway design, with each pixel in the image providing detailed condition and elevation information. 3 Images courtesy of The American Surveyor
