Utilities Advisory Committee Memo DATE: January 13, 2015 To: Utility Advisory Committee FROM: Kathryn Neal, P.E., Engineering Manager SUBJECT: Professional Services Agreement with CH2M Hill Engineers, Inc. 2015 Water Utility Engineering Services, Contract WA15-005 for E Street Reservoir Improvements, Project WT01-2009. Summary: Professional engineering services are required to complete the design of pipe and valve revisions and a new pressure reducing valve(PRV) station at the E Street Reservoir. The proposed contract with CH2M Hill Engineers provides scope and budget for design and construction support for the E Street Reservoir Improvements, and also provides a budget of$15,000 that may be authorized during 2015 for other Water Utility engineering services that may become necessary. Recommendation: Provide a favorable recommendation to City Council to approve and authorize the City Manager to sign the 2015 Water Utility Professional Services Agreement with CH2M Hill Engineers in an amount not to exceed $47,556. Background/Analysis: The E Street Reservoir, constructed in 1918, is the oldest of the City's water distribution system storage reservoirs. The Reservoir is a reinforced concrete structure with a steel-supported aluminum roof cover installed in 1987, and a hypalon liner installed in 1990. In October 2012, HDR, Inc. was hired to perform an inspection of the E Street Reservoir. The objectives of this inspection were to obtain an evaluation of the reservoir's cover and cover support system above the water level, and make recommendations regarding the recoating of the reservoir cover's steel structural support system. The inspection revealed severe corrosion and consequent diminished structural load capacity. The design team next investigated several alternative designs to repair/replace the roof and the liner system, or to replace the reservoir entirely. The resulting cost estimates ranged from $450,000 to $1,600,000. Then in September 2013, ground-penetrating radar investigations of the reservoir floor revealed large voids under the reservoir, most likely caused by leakage during the decades before the liner had been installed in 1990. These findings triggered an investigation of whether or not the E Street Reservoir is indispensible. In March 2014, CH2M Hill Engineers, Inc. was tasked with using the existing water system N:AUAC\MEETINGS\UAC2015\UAC011315\2015 Water Utility Engineering Services -E St Reservoir.docx January 13,2015 Utilities Advisory Committee CH2M HILL Engineers,Inc. 2015 Water System Engineering Services Agreement Related to the WTO1-2009 E St Reservoir Rehab Project. Page 2 hydraulic model they had developed, to answer that question. The analysis was presented in a technical memorandum including three main elements: 1. Storage Volume Analysis: Reviewed whether or not the E Street Reservoir volume is needed to meet Washington State Department of Health (DOH) storage requirements 2. Distribution System Hydraulic Analysis: Addressed the impact to potential removal of the E Street Reservoir on normal operating flows and fire suppression flows in the Low Pressure Zone. 3. Surge Analysis: Addressed the impact of removing the E Street Reservoir from service on pressure surges within the Low Pressure Zone. The hydraulic analysis concluded: 1. The City's water distribution system has sufficient storage to meet DOH requirements if the E Street Reservoir is removed from service. 2. If a single PRV is installed in the vicinity of the E Street Reservoir Site, the City's water distribution system can satisfy all flow demands, including fire flow requirements, without the E Street Reservoir in service. 3. The E Street Reservoir provides little benefit to the Low Pressure Zone during a pressure surge event. Based on the conclusions of the hydraulic analysis, the most economical solution is to make modifications at the reservoir that will allow it to be taken out of service. The installation of a PRV and associated pipe and valuing modifications will allow continued use of the E Street Reservoir until imminent failure, at which time the City will be able to transfer water supply to the Low Pressure Zone from the reservoir to the PRV in a timely manner with minimal impact to residents. The estimated cost of these improvements is $200,000 for design and construction. The negotiated amount for engineering services related to E Street Reservoir is $32,556, and the additional amount that may be authorized in 2015 for other Water Utility engineering is $15,000, as identified in the following table: TASK DESCRIPTION AMOUNT Task 1 Design of Piping Revisions at E St Reservoir $13,412 Task 2 Design of Pressure Reducing Station $13,000 Task 3 Bidding and Construction Support $6,144 Task 4 Directed Services $15,000 TOTAL $47,556 It is requested the Utilities Advisory Committee provide a favorable recommendation to City Council to approve and authorize the City Manager to sign the 2015 Water Utility Engineering Services Agreement with CH2M Hill Engineers in an amount not to exceed $47,556.
