JMT performed in-service safety inspections through a five-year program for 39 bridges and culverts, and 12 sign structures, including underwater inspections of 18 bridges, throughout the City of Hampton in accordance with the requirements of the Virginia Department of Transportation (VDOT) and National Bridge Inspection Standards (NBIS). Inspection services included:

In addition, the scope of services included performing load rating for bridges in accordance with VDOT and NBIS requirements. The load rating services included performing the load rating using AASHTOWare Bridge Rating software (formerly referred to as VIRTIS) and other approved software, preparing load rating reports, and providing recommendations on load restriction postings.
