The Basic TAMP
A TAMP describes an agency’s goals and objectives for maintaining its assets over time. It describes an agency’s most critical assets, and their current condition. It also describes the agency’s strategy for preserving its assets, predict future conditions given the agency’s planned investments, formulate and deliver an investment plan, and discuss how the agency manages risks to its assets.
This section discusses the requirements for a TAMP that is consistent with TAM leading practice. A TAMP includes:
- TAM Policies, Goals and Objectives
- Asset Inventory and Condition
- Life Cycle Planning Approach
- Predicted Asset Conditions
- Investment Plan
- Risk Management
Note there are additional specific requirements for a TAMP that is prepared to comply with Federal requirements. State DOTs are required to prepare a TAMP with a 10-year horizon that includes, at a minimum, NHS pavements and bridges. Transit agencies that receive Federal funds are required to prepare a TAMP with a four-year horizon that includes their revenue vehicles, facilities, infrastructure, and equipment (including service vehicles). FHWA provides a checklist of elements of TAMPs compliant with Federal requirements: https://www.fhwa.dot.gov/asset/guidance/certification.pdf. A similar FTA document is available at: https://www.transit.dot.gov/sites/fta.dot.gov/files/docs/regulations-and-guidance/asset-management/55371/compliancechecklistfy2018_0.pdf.
TAM Policies, Goals and Objectives
A TAMP summarizes an agency’s policies, goals, and objectives and describes how its approach to TAM helps support these. For instance, the document might discuss how maintaining assets in good repair supports the organization's broader goals for strengthening mobility and supporting economic development. It may also describe how the organization defines the desired state of repair of its assets, or criteria for evaluating whether or not an asset is in good repair. A clear linkage between TAM objectives and the achievement of wider agency goals should be directly illustrated within the TAMP.
Asset Inventory and Condition
In preparing the TAMP, the agency must decide which asset classes to include in the document, and the level of detail in which the assets are described. For a highway plan, critical assets include pavements and bridges. A TAMP that is prepared to comply with Federal requirements must include these assets on the National Highway System at a minimum. Other assets addressed in a highway TAMP may include, but are not limited to: drainage assets such as culverts; traffic and safety assets such as signs, signals, and lighting; maintenance facilities; and Intelligent Transportation System (ITS) devices. For a transit plan, critical assets include revenue vehicles, facilities, infrastructure (for agencies that operate fixed guideway) and additional equipment, such as service vehicles.
A TAMP should provide a listing, typically in summary form, of the assets the agency has identified for inclusion. For each asset class the document should describe the physical extent of the asset, and current asset conditions. Chapter 3 of this document describes approaches for measuring asset condition and performance. Note that FHWA and FTA have developed specific requirements for reporting asset conditions for highway and transit assets, respectively. However, agencies are not limited to these measures, and may include multiple measures of condition in their TAMP to help provide a complete description of asset conditions.
Often it is helpful to place the data on an agency’s asset portfolio's current condition into some context. For instance, the TAMP may include photographs of representative asset condition to help illustrate what is meant by a given value for a performance measure. Also, a TAMP may include historic data on asset conditions to help illustrate condition trends.
Life Cycle Planning Approach
A critical component of a TAMP is a discussion of how an agency maintains its assets over their life cycle. Ideally the agency’s approach to life cycle planning should help maintain assets at a target level of service over their life cycle in the most efficient manner possible, while supporting agency goals and objectives. This section of the TAMP should describe the treatments the agency typically performs on its assets, and detail the analytical approaches it uses to assess investment needs, prioritize work, and predict future asset conditions. If the agency has implemented specific management systems for one or more of its asset classes, such as pavement, bridge or enterprise asset management systems, this section should describe those systems and how they are used to support decision making. Chapter 4 of this document provides further detail on life cycle planning.
Predicted Asset Condition
This section of the TAMP should describe how an agency’s assets are predicted to perform in the future. The horizon of the predictions should be commensurate with the horizon in the investment plan described in the next section. Typically the planning horizon is at least four years, but may be up to 20 years.
This sections should show what conditions are predicted given expected funding, as well as any gaps between predicted performance and the agency’s goals for its assets. This section may include results for multiple funding scenarios, particularly if there is uncertainty concerning future funding, or if including results for multiple scenarios helps document the process used to prioritize funding. For instance, the document might show predicted asset conditions over time given the current funding level, predicted future funding, and scenarios with more or less funding than the predicted level.
The TAMP should detail planned investments given expected funding. Depending upon the agency size and assets included in the plan, the document might include specific investments the agency plans to make or projected funding levels by asset class and type of work. This section may provide additional details on sources of funding, and the agency’s specific strategy for investing in its assets considering available resources.
Managing transportation assets also entails managing risk. Considering risk is important in developing a TAMP, for the simple reason that there are various risks that, if they occur, may impact an agency’s ability to follow its TAMP. For instance, the occurrence of a natural hazard may require an agency to spend significant resources in response, to address or mitigate damage. Employing risk management strengthens asset management programs by explicitly recognizing that any objective faces uncertainty, and identifying strategies to reduce that uncertainty and its effects. This section of the TAMP should describe the agency’s approach to risk management. It should identify major TAM-related risks and describe the agency’s approach to addressing these.
To ensure alignment with the requirements of MAP-21, Colorado DOT developed a requirements checklist that provides a quick reference/summary of the legislation requirements. The checklist is based on FHWA guidance (Transportation Asset Management Plan Annual Consistency Determination Final Guidance) that was issued in February, 2018. Its content was provided to help DOTs ensure their TAMPs are compliant and consistent with statute and regulatory requirements.
