Maintenance Delivery
VDOT uses State crews, project-level contracts, ‘as-needed’ contracts and asset maintenance contracts
to maintain bridges and culverts. District-wide, as-needed maintenance contracts are set-up with bid
items for commonly-needed work at structures. Turnkey Asset Maintenance Services (TAMS) contracts
provide minor maintenance and incident management on interstate highways. VDOT makes great use
of contract maintenance. In FY 2008, $891 million of $1.20 billion (74%) of highway maintenance ex-
penditures were paid to the private sector
