Mr. D. Allen Saxon, Jr. Assistant Director, Wastewater Augusta Utilities Department 360 Bay Street Suite 180 Augusta, OA 30901 August 28, 2007 SL # 30453 Project #: RO-5847-SD Re: Professional Services Budget, Messerly Improvements Dear Mr. Saxon: The Messerly Design Group (MDG) completed design on the Messerly Improvements Project in June 2005. Since that time, we have worked closely with the Project Management Team to develop the best possible construction pricing for the project. When the original professional services budget was developed, the project was to be constructed utilizing the traditional design-bid-build delivery method. During design, the project team decided that the Construction Manager at Risk (CMAR) delivery method would offer economic, constructability and operational advantages. Consequently, MOO's scope has changed to accommodate the change to CMAR. Also, during the development of the project, additional tasks have been performed to address critical needs not included in the original scope, and to tailor the project to conform to AUD's available funding. These tasks include significant redesign resulting from a Value Engineering analysis, and redesign of the south aeration basins. These efforts have resulted in reducing the guaranteed maximum price (GMP) of the project from $86,300,000 to approximately $70,000,000. An itemization of the original and proposed professional services budget is attached for your reference. Please contact me if you have questions or comments.

Messerly WPCP Master Plan Implementation Phase 1 Project Department: Utilities caption2: Approve a supplement to the contract with Messerly Design Group, LLC (MDG) in the amount of$1,218,171 for additional scope of work required through construction of the James B. Messerly WPCP Master Plan Implementation Phase 1 Project. Background: MDG has worked closely with both our previous and current construction management firms to value engineer the project, evaluate the impact of proposed cost saving approaches and modify the design as appropriate. In addition there have been two additional Utilities Department projects that were required to coordinate design with the Messerly Plant project. Analysis: The total amount of this requested supplement to MDG's contract is $1,218,171. A portion of this amount ($274,911) is to cover additional expenses related to the original scope of work due to the change in project delivery approach from traditional design- bid-build to Construction Manager at Risk and an increase in labor cost due to delays in beginning construction. The majority of the requested amount ($943,260) is due to the additional work that has been required to work with the project team in refining the project and design coordination to accommodate the other Utilities Department projects. The additional work on this project has resulted in a reduction of the overall project cost of approximately $14 million since October 2006. Financial Impact: $1,218,171 from Utilities Department Capital Improvement Funds Alternatives: 1) Approve the requested supplement; 2) Disapprove and negotiate another contract for engineering through construction (not recommended) Recommendation: Approve this requested supplement to the contract with Messerly Design Group, LLC in the amount of $1 ,218, 171.
