RE:	January 07, 2014 Agenda Item – Advertise RFP R1401 for Preliminary Engineering Services for Project UT1403 Evaluation of Rehabilitation and Replacement Options for the Stratford Elevated Tank

Please include the following item on the City Commission Agenda for consideration at the January 07, 2014 meeting:

Authorize Staff to advertise a Request for Proposals for RFP R1401 for Preliminary Engineering Services for Project UT1403 Evaluation of Rehabilitation and Replacement Options for the Stratford Elevated Tank

Project Description:

The 2012 Integrated Water Utilities Plan and adopted scenario 5 Capital Improvement Plan identified and provided funding for rehabilitation and restoration of coatings systems for elevated and ground storage facilities within the water distribution system during the five year period between 2013-2017.

Project Details:

The City of Lawrence water distribution system is divided into two pressure zones, West Hills (High Pressure) and Central Service (Low Pressure) and contains approximately 460 miles of transmission and distribution piping as well as elevated and ground storage facilities as follows:

West Hills:

Stoneridge Elevated Storage, 2008 – 1.5 MG

6^th Street Elevated Storage, 1967 – 0.5 MG

Stratford Elevated Storage, 1954 – 0.5 MG

Central Service:

Kasold Ground Storage & Booster Pumping, 1970 – 1.5 MG

Oread Ground Storage & Booster Pumping, 1931 – 1.0 MG(S), 1954 – 1.4 MG(N)

Harper Elevated Storage, 1967 – 0.5 MG

The 2012 Integrated Water Utilities Plan identified the coatings on the Stratford, 6^th Street, and Harper Elevated Storage Facilities for rehabilitation/restoration as part of the tower protective coatings project. Elevated and ground storage facilities within the water distribution system are critical to maintaining system pressures, system water quality, and providing volume to meet system demands.

Staff have identified the Stratford elevated storage facility, located at 1225 Sunset Drive and shown on the attached map, as the first priority of the project. The selection of the Stratford facility was based on age; known condition, content, and required abatement of the existing epoxy based interior and lead based exterior coatings; required repairs and/or replacement of the cathodic protection, venting, and structural systems; and accessibility limitations with respect to the manway and ladders. An inspection of the existing facility was performed by Ozark Applicators, LLC in October of 2010 and the findings thereof are attached for reference.

Staff have prepared a Request for Proposals for Preliminary Engineering Services related to the Tower Protective Coatings Project and defined a limited initial scope for the project. Staff are proposing to initially contract with a qualified engineering firm to complete an alternatives analysis. The alternatives analysis shall include, a comparison of required restoration and modifications, operational impacts, and costs of maintaining the existing tank with the design, construction, operational impact, and costs thereof for a new facility including demolition of the existing elevated storage tower and relocation of existing communications and cellular equipment. Platting, land use permitting, and variances as required will be addressed for all alternatives presented in the analysis. Upon completion of the alternatives analysis, staff are proposing to extend the engineering services contract to include additional design and construction phase services as required to implement the recommended alternative with the negotiation of a supplemental agreement.

Project Funding:

The program is included in the Department of Utilities 2013/2014 Capital Improvement Plan and adopted Rate Plans.
