LiDAR Chesapeake Bay TMDL Interstate Scanning
One DOT was required to address harmful roadway runoff in the Chesapeake Bay watershed by purchasing nitrogen credits. In order to qualify for a reduction in required nitrogen credit purchases and demonstrate the efficacy of their mitigation programs, the DOT needed to measure the exact acreage of impervious pavement and gather precise data of pervious areas over 775 miles of interstate.
Interstate Maintenance Office Snow Monitoring
VDOT required extra roadway monitors during severe winter weather events to ensure 300+ miles of interstates and major state routes around the Richmond area remained open for the traveling public and commerce.
Safety Rest Area Inspection & Water/Wastewater Monitoring
VDOT’s Safety Rest Area program encompasses 41 rest areas across Virginia that require inspection and water and wastewater management so the traveling public has clean and functional facilities for safety breaks.
Effectively Scope Mowing Acreage
VDOT Staunton district lacked veriable data, leaving them vulnerable to mowing scope creep. As a result, they had no recourse to correct a dramatic increase in mowing costs for approximately 236 centerline miles of the Interstate system in the Staunton District.
Pavement Engineering
VDOT Salem District lacked qualified staff to develop its paving program, which encompassed 9,200 miles of roads in 12 counties and 14 cities and towns.
Rest Area Condition Assessments
A full-service maintenance provider won a 5-year, performance-based contract to maintain 12 of the 43 rest areas in Virginia. The contract provided no baseline condition assessment or documented deficiencies for these rest areas which left the contractor open and subject immediately to performance penalties. A complete and comprehensive facility condition assessment was required before the contractor could effectively perform its contract duties.
