KPFF Consulting Engineers for the Washington State Department of Corrections
White Shield supported KPFF and DOC with a pre-design topographic survey and mapping of the 13th Avenue right-of-way for this road widening and infrastructure upgrade project. The project consisted of a full survey of approximately 2800’ of roadway corridor along 13th Avenue, including road surface, curb lines, driveway chutes, sidewalks, ramps, fences and any buildings adjacent to the right-of-way, and all other existing features within the right-of-way. The survey also included any above ground utilities, and paint marks of underground utilities provided by the one-call locate service. High Definition Scanning was also performed to provide accurate power line elevation information.
