RE:	March 25, 2008 Agenda Item – Construction Phase Engineering Services Agreement for the Southeast Sanitary Sewer Benefit District

Please include the following item on the City Commission agenda for consideration at the March 25, 2008 meeting:

Authorize the City Manager to execute a Engineering Services Agreement with Peridian Group Inc. in the not to exceed amount of $249,906.31 for Construction Phase Engineering Services related to the Southeast Sanitary Sewer Benefit District’s 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. 26^th 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 Benefit Districts for the improvements noted above at an estimated financial commitment of $806,161.00.

Douglas County has awarded the construction contracts for the Benefit District projects and construction is set to begin at the end of the month.

As part of the City - County Benefit District Cooperation agreement the City is to provide for construction phase inspection and engineering services. The costs of these services are charged, by the City, back to the Benefit Districts. The City ultimately pays its share of the construction phase inspection and engineering services through its participation in the Benefit Districts.

Peridian Group Inc. are the design engineers engaged by Douglas County for the design of the Benefit District facilities. Based on their existing knowledge of the project City Staff have negotiated an Engineering Phase Services Agreement with Peridian Group Inc. for the construction phase inspection and engineering services. The scope of work includes fulltime resident inspection, review of submittals, materials testing, field survey, clarifications and interpretations of design documents in response to contractor inquiries and generation of as-built plans.

Project Funding.  Funding for the project will come from the Utility Department Capital Improvement Project non-bonded construction fund.

Action Request. Authorize the City Manager to execute a Engineering Services Agreement with Peridian Group Inc. in the not to exceed amount of $249,906.31  for Construction Phase Engineering Services related to the Southeast Sanitary Sewer Benefit District’s Nos. 1, 2 & 3.
