RE:	January 8, 2008 Agenda Item - Expansion of Wet Weather Storage Capacity at Pump Station 09 (Four Seasons) Utilities Department Project #UT0705 Advertise a Request for Proposals

Please include the following item on the City Commission agenda for consideration at the January 8, 2008 meeting:

Authorize staff to distribute a Request for Proposals for a Construction Management Agreement for the expansion of the wet weather storage capacity at Pump Station 09 (Four Seasons).

Project Background

The 2003 Wastewater Master Plan identified improvements to Pump Station 09 located west of 31^st and Kasold that included expansion of the wet weather storage capacity by 2.5 million gallons. The additional wet weather storage is critical to relieving collection system capacity issues and for the continuation of development along the 31^st Street corridor. This project was to be one of the first projects approved for construction within the Wakarusa Water Reclamation Facility (WWRF) contract. While the timing of the construction of the WWRF is being reviewed, there is a more immediate need for the additional storage capacity at Pump Station 09.

Project Status/ Details

While the City reviews the timing and scope of the WWRF facility, staff proposes to seek a construction management relationship for design and bidding services for the project. Staff proposes to publicly solicit from Requests for Proposals a qualified construction management firm. A construction management agreement allows for all construction work to be competitively bid or quoted, while providing construction oversight of the project.

A variation of this was used on the 2002 Phase I Filter Expansion at the Clinton WTP. In this case, in addition to the engineer a contractor was hired as the construction manager to help expedite the construction of the project. However, the contractor was allowed to self perform a limited amount of work with all remaining work competitively bid. Staff plans to recommend that all construction work will be competitively bid for the Four Seasons project.

The following project schedule is anticipated.

Execute Construction Management Agreement: April, 2008

Complete Design: July, 2008

Construction Contract: September, 2008

Complete Construction: February, 2009

Project Funding

Funding for this project is through the Utilities Capital Improvement Program bonded funds.

Action Request

Authorize staff to distribute a Request for Proposals for a Construction Management Agreement for the expansion of the wet weather storage capacity at Pump Station 09 (Four Seasons).
