PILLAR
This mobile LiDAR scan gathered guardrail length inventory and assessed its condition in accordance with VDOT’s Maintenance Rating program. This data enables VDOT to develop a maintenance plan, allocate the work force and secure a budget for the project.
Using mobile LiDAR and our automatic feature extraction tools, we determined Virginia Department of Transportation (VDOT) Staunton District’s Interstate mowing acreage for all of their mowing scenarios. From paritial to full width and tractor to slope to hand mowing, we calculated the acreages from the post-processed and extracted LiDAR point cloud. We also produced shape files and corresponding GIS attributes identifying each mowing area for VDOT’s database.
PILLAR utilized decades-old plan sheets, LiDAR scanning technology, and crews on the ground with an iPad and InfraTrak to conduct inventory and assess more than 40 asset types on interstates and U.S. highways in the Salem Districts. 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.
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.
VDOT District 4 uses PILLAR employees to assist in verifying recommended repairs identified in the NBIS reports and ensuring those repairs are made. The work is on bridges throughout the district primarily on primary and secondary roads. Our responsibilities include verifying work, labor, material quantities, and traffic control restrictions as well as being a liaison to the Department and providing recommendations on repairs due to changed field conditions.
PILLAR’s inspection department was hired by Wythe County to inspect and oversee the installation of a rail spur line into the county’s industrial park. We performed site visits and provided progress reports with payment qualities to ensure the job was done to specifications.
Wythe County hired PILLAR to inspect the installation of a new sewer line and pump station from Progress Park to an existing main. We observed the installation, testing, water monitoring of the new line, reviewed the contractor’s pay schedule for accuracy and provided daily logs of progress and material documentation, as well as helped solve problems in the field. Special construction circumstances included boring under both Norfolk & Southern Railroad and Reed Creek.
PILLAR was contracted to monitor and inspect the installation and final work product of a new 20-inch water line which will eventually tie into the Austinville Water Plant and service Wythe County’s industrial park. We observed installation, testing, and water monitoring, while provided guidance to help solve issues in the field. PILLAR reviewed the contractor’s pay schedule for accuracy and provided daily logs of progress and material documentation.
PILLAR’s inspection department was hired by Wythe County to inspect and oversee the construction of a new road leading to the Gatorade Processing Plant in the Progress Park industrial park. The project also included a railroad crossing. PILLAR conducted site visits and provided progress reports with payment qualities to the county.
