Assets inventoried included 4,700 signs, 1,198 guardrail terminals, 1,088 drop inlet catch basins, 828 light poles, 408 pavement messages, and 205 miles of longitudinal guardrail. The Virginia Department of Transportation took this information and used it for the development of its work plans and budgets.
VDOT District 6 Pipe Assessment
PILLAR collected inventory and assessed the condition of all the drainage pipe and structures located along the I-95 corridor (mainline and ramps) in Caroline, Spotsylvania, and Stafford Counties for Virginia Department of Transportation (VDOT) Fredericksburg District Office. PILLAR’s office personnel geo-referenced design plan sheets to obtain the initial GPS position of the structures into a GIS database.
VDOT District 1 needed to quantify several large overhead signs along the interstate which were scheduled for replacement. They required us to gather the dimensions as well the wording on the current signs so new signs can be fabricated to match the existing sign. This allowed VDOT to swap out the signs without having to change or modify the support structure. We initially obtained the information via mobile LiDAR and verified measurements utilizing conventional and traditional survey methods.
