MEMORANDUM 04-49

To: Walt Wrede, City Manager

From: Carey Meyer, Public Works Director

Date: March 16, 2004

Subject: Transmission Main PRV Station Improvements

Design Contract Award Recommendations

The City obtained a grant from the Alaska Department of Environmental Conservation (ADEC) in the amount of $2,245,714 (30% City match required) to complete the 1.0 MG water tank and transmission main improvements. The water tank was completed last year for approximately $1,500,000 and the remaining funds are available to complete improvements to the transmission mains.

As part of the water/sewer master planning effort, preliminary results of the evaluation of our transmission mains indicates that 3 pressure reduction valve (PRV) vault stations need to be replaced/relocated. Input from our maintenance personnel confirm that these stations are located in areas that are difficult to access and are in poor condition. Based on the fact that Bristol Environ-mental is completing the master plan and the modeling of the water system, it is reasonable to award the design of the PRV Station improvements to this firm. Attached is copy of proposed addendum to the existing contract with Bristol Environmental which would authorize the completion of design.

Total remaining funds in the grant - $750,000

Current Proposed Project

PRV Station Improvement Design - $53,000

PRV Station Construction - $450,000

Subtotal $503,000

Future Proposed Project

Paint Brush Avenue Booster Station Design $25,000

Paint Brush Avenue Booster Station Construction $100,000

West Hill Transmission Main Design $122,000

Subtotal $247,000

Recommendation: The Council authorize the City Manager to execute all documents necessary to design the current project (PRV Station Improvements) and authorize the expenditure of $53,000 from the grant funds to fund this effort. Once this work is completed, the City Manager will present a budget to complete the construction of the PRV Station improvements and other future projects with the remaining grant funds.
