Operations & Maintenance Surveying & Mapping


Meticulous and accurate surveying and mapping highlight often-overlooked issues and create a solid foundation for any operations and maintenance plan.

Knowing what you have, where you have it, and its condition provides valuable information for the development of a successful operations and maintenance plan. Incorporating existing conditions with planned changes models the final desired product. We invest in the latest technology, software, and practices to reduce delivery time, increase efficiency, and produce a complete picture.

VIR LiDAR

VIR LiDAR

Virginia International Raceway (VIR) must submit track details to Federation Internationale De L’automobile (FIA) to be a recognized motor racing circuit. PILLAR used mobile LiDAR to scan the entire facility to obtain and render a 3D terrain model of the VIR site in order to meet FIA requirements and be a certified venue. Track characteristics including centerline elevation and alignment, markings, barriers, run-off areas, kerbs, fences, pit lane and buildings needed to be documented and submitted in a prescribed CAD format. We used photographs and automatic feature extraction to locate and identify these characteristics, submitting them to FIA.

VDOT district 4 Guardrail Scan

VDOT district 4 Guardrail Scan

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.

VDOT 1 inventory collection

VDOT 1 inventory collection

PILLAR was hired to implement processes and procedures to collect and assess inventory for 40+ asset types covering 295 centerline miles on I-81, I-381, & I-77. We used a combination of geo-referencing to collect data, including 50-60 year old plan sheets, Mobile LiDAR Scanning with data extraction, and field condition assessments utilizing VDOT's Maintenance Rating Program. We inventoried 1,098 drop inlet catch basins, 6,445 signs, 1,349 guardrail terminals, 216 miles of longitudinal guardrail, 320 light poles, and 337 pavement messages.

VDOT District 8 Mowing Acreage Scan

VDOT District 8 Mowing Acreage Scan

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.
