TAMP & MAP-21 §1106 Compliance

What MAP-21 §1106 requires in a TAMP

A Transportation Asset Management Plan (TAMP) is the risk-based, performance-driven plan a state DOT uses to manage its pavement and bridge assets. Under MAP-21 §1106 and FHWA's implementing rule (23 CFR 515), every state must develop and maintain a TAMP that covers, at a minimum, all National Highway System (NHS) pavement and bridges — including NHS assets the state does not own. FHWA requires the plan to contain a defined set of elements, and a state that has not developed and implemented a compliant plan can see its maximum federal share for National Highway Performance Program projects reduced to 65% for that fiscal year.

• Asset inventory and condition for NHS pavement and bridges.
• Performance gap identification against state targets.
• Life-cycle planning and management.
• Risk management analysis.
• A 10-year financial plan.
• Investment strategies that work toward the targets.

How capital planning software keeps a TAMP current

TAMP software is the tooling a DOT uses to maintain the condition, life-cycle, risk, and investment-strategy work behind the plan between formal updates. A TAMP is not a document you write once every few years; FHWA expects it to be used and kept current. InfraMind is the owner-side planning layer that sits on top of a DOT's pavement and bridge management systems and helps it:

• Forecast pavement and bridge deterioration so performance gaps are projected, not just measured after the fact.
• Run budget-constrained investment strategies and compare how funding levels move network condition toward targets.
• Score and document risk so the risk-management element is defensible to FHWA and to leadership.
• Produce an audit-ready financial plan and investment strategy that ties condition to capital.

The condition data behind a TAMP also feeds other reporting. The same assessments support GASB 34 modified-approach reporting, and the prioritized backlog behind the investment strategy is what makes a DOT grant-ready before the IIJA funding cliff.
