Dam Specification Review Tool Finalized!  Version 1.0 now available.
Specifications – always a challenge to review and write, especially for dam construction projects. To assist engineers that review and write dam specifications, AECOM, out of Denver Colorado developed the Dam Specification Review Tool version 1.0. The tool was developed in Microsoft Excel 2010 and contains indexed worksheets that pertain to major parts of a dam construction project, including general requirements, earthwork, drainage pipe, concrete and water control. Each worksheet systematically reminds users of important things that need to be considered through a series of targeted questions. The Tool addresses the most commonly used dam construction topics. Flexibility is provided through the addition of worksheets that can be tailored for a specific project or agency requirements.

This project was funded by the National Dam Safety Act Assistance to States Grant awarded to Montana. Version 1.0 has incorporated comments provided during the Beta test.
