Projects Survey

Olive Street – Sample Street Overpass Survey

South Bend, Indiana

DLZ provided surveying services for an intersection and bridge improvement project near a railroad in an urban area of South Bend, Indiana.

Services included:

  • Establishing a horizontal and vertical control network
  • Topographic mapping of 7000’ of mainline roadway and 4000’ of side streets
  • Extensive sewer detailing/connections of over 250 sewer structures and outfall pipes
  • High definition scanning (HDS) of the bridge faces and top of rails of tracks
  • Location control route survey plat and right-of-way dedication plat

Field work was completed in less than two months using GPS, robotic total stations, and HDS laser scanner.  Scanning was used for the location of the rails to avoid costly railroad permits and to keep the crews safe from train traffic.  DLZ mapping was exported to various formats so the map could be shared with sub-consultants.
