Navarro & Wright Consulting Engineers, Inc. conducted all ground surveys to supplement aerial photography conducted by District 8-0 and generate base mapping for this large highway project, which includes approximately six miles of state highway, four overpasses, two railroad crossings, and other large drainage structures. In order to minimize interruption of traffic, N&W work closely with the District’s Traffic group to insure safe and efficient survey practices for all bridge underpasses and utility locations. The utility coordination for the project area included 17 different utility companies. Cross-sections were taken at close intervals to facilitate design of roadway improvements. The geotechnical engineering phase of this project includes Subsurface Investigations for construction of noise walls, drilling inspection, supervision, and preparation of the Structure Foundation Reports for three walls.
