Developing a Model Work Plan

The model work plan submittal should address an understanding of the model objectives, project constraints, and overall approach should be developed. In order to develop this project understanding, the dam owner and engineer/modeler should meet to discuss the modeling approach, including items that can substantially impact cost and/or schedule. Commonly, the regulator is not involved in early scope of work discussions that have financial or contractual components.

General Considerations for All Models

Describe the model purpose and justification of need.

Summarize the overall assumptions and modeling approach.

Note the guidance documents used as basis for approach (e.g., State published guidance, USBR Design Standards, FERC Engineering Guidelines for Evaluation of Hydropower Projects, USACE Engineering Manuals, etc.)

Summarize the possible outcomes and expected outcomes.

Summarize the data that is available or will be collected as part of the process.

Provide an assessment of which assumptions are foundational (i.e., modifying assumptions would require additional communication and concurrence) and which can be modified through the analysis process.

If an Independent Review is planned, describe the relationships and responsibilities of the parties involved (third party, internal to modeling firm or expectations for regulatory agency review)

Note factors that may increase the modeling level of effort. This is also a discussion item with the dam owner during scope of work negotiations.

Describe how interim and final modeling results will be presented (written report, presentation, discussion, etc.). This is also a discussion item with the dam owner during scope of work negotiations.

Include a recommended schedule for submittals, review & regulatory feedback. Note critical deadlines to avoid project delays. Request regulatory agency concurrence with schedule as part of feedback on pre-analysis submittal.
