City of Sandy Springs: Sidewalk Project – Glenridge Drive, Mt. Vernon Highway to Abernathy Road

SEI performed 3D terrestrial laser scanning along Glenridge Drive in Sandy Springs, GA in support of a sidewalk and streetscape project. All utility services including sewer and water were further located by conventional survey methods to include structure depths. Scan data was used to create highly detailed roadway cross-sections and accurate spot elevations for design purposes. Through a combination of conventional survey data and the 3D scans, the existing and proposed underground utilities are being modeled 3 dimensionally...

Union City: SR 138 Project

SEI utilized survey grade GPS units to establish survey control throughout each route for Vertical (MSL) and horizontal control. These control points were confirmed for accuracy by running a level loop on each route. A robotic total station and total station were utilized to gather the data required for the Base Map. These include; topography, creeks, streams or ditches, storm water and sanitary sewer pipes and associated structures, curb, gutter, pavement, striping, traffic control devices, all above ground visible utilities, property corners, right of way markers and any unusual features...
