RE:                  City initiated design costs related to optional bidding configurations of Pump Station PS49 in the Douglas County Sanitary Sewer Benefit Districts Nos. 1, 2 & 3.

 

Please include the following item on the City Commission Consent Agenda for consideration at the April 8, 2008 meeting.

 

Authorize payment in the amount of $26,000.00 to Olsson & Associates for City initiated design costs related to optional bidding configurations of Pump Station PS49 in the Douglas County Sanitary Sewer Benefit Districts Nos. 1, 2 & 3.

 

Project Description - The Douglas County Sanitary Sewer Benefit Districts Nos. 1, 2 & 3 are constructing sanitary sewer facilities which will ultimately serve the current Fairfield Farms West development and the area east of O’Connell Rd generally bounded on the north by K10, the south by N1300 RD and on the east by E1750 RD.  

Construction of these Benefit District facilities will allow the immediate decommissioning of three existing City sanitary sewer pump stations; PS41 on East 27th Terrace; PS47 at E. 26th Street and O’Connell Road, and PS38 located southeast of Franklin Rd and East 25th Street.  The flows to these pump stations will be routed by new gravity sanitary sewers to the regional pump station PS49 being constructed as part of the Benefit District.  The decommissioning of these three pump stations represents capacity, operational and maintenance benefits to Utilities Department.

Project Status - Per the City Commission’s authorization on June 13, 2006 the City agreed to participate in the construction of the Benefit Districts for the improvements noted above at an estimated financial commitment of $806,161.00.

During the design of the project the option of constructing the pump station structures to accommodate the areas full sanitary sewer capacity needs instead of smaller structures sized to only accommodate the needs of the current benefit district participants was raised by the Utilities Department and Douglas County’s design engineers Peridian Group and Olsson & Assoc. It was estimated at the time that the cost to provide the additional design work and produce bidding documents that allowed the bid of two alternate pump station configurations would not exceed $28,000.00. Authorization to pursue the additional design effort was provided by the City Manager’s office.

 

Based on the City’s authorization Douglas County has awarded the construction contracts for the Benefit District projects based on the bid for the construction of the larger pump station structures sized for the areas ultimate capacity. The costs for the additional design and construction are within the amount of financial participation originally authorized by the City Commission.

 

Project Funding.  Participation in the Benefit District as authorized has been included in the Department of Utilities Capital Improvements Plan. Funding for the design cost will come from the 2008 Utility Department Capital Improvement Project non-bonded construction fund.

 

Action Request.  The Utilities Department is seeking approval from the City Commission to make payment in the amount of $26,000.00 to Olsson & Associates for City initiated design costs related to optional bidding configurations of Pump Station PS49 in the Douglas County Sanitary Sewer Benefit Districts Nos. 1, 2 & 3.
