The proposals were evaluated by a three -member committee. The proposals were rated on the basis of: qualifications, experience with similar projects, work plans, and overall approach.

The proposers were requested to submit a fee schedule reflecting performance of the basic study as well as a separate fee to perform the additional follow-up work. After evaluating the proposals, corresponding sealed fees submitted by the top three firms were opened. The evaluation scores and fees for each proposal are as follows:
