UT0919CS Miscellaneous Pump Station Improvements

OCTOBER 2009 REPORT

Project Number: UT0919CS General Location: Various locations throughout City limits (map attached) includes

pump stations 12, 13, 15, 22, 23, 27, 28, 31, 34, 35, and 37. Project Budget: $2,582,000.00 (estimated) Project Start Date: 09/01/2009 City Commission authorized advertisement of RFP Project End Date: Spring 2010 (estimated) Engineer: TBD Engineering Cost: $TBD Engineering Invoiced: $0.00 Contractor: TBD Construction Cost: $TBD Change Orders: TBD Construction Invoiced: $0.00 Other Costs: $TBD General Project Description The City of Lawrence operates a number of small (80 to 300 gpm) vac-prime wastewater lift stations to convey sewage to its wastewater treatment plant. These lift stations were installed by the development community to provide service to localized areas of development. The lift stations are typically located in utility easements adjacent to or surrounded by residential property. The existing stations are 15 to 40 years old, many have exceeded their useful lives, are unsafe to maintain as several of the lift stations are classified as confined space entry, many are no longer supported by the original manufacturer and require replacement to bring them up to current KDHE minimum design standards. The general intent of the project is to replace a number of the existing vac-prime lift stations with rail-mounted submersible pumps, valve vault, overflow prevention, backup power connection and flow metering in order to meet current KDHE minimum design standards. Some modifications to the existing gravity lines upstream of each station may be required. The City will provide wet well level instrumentation, programmable logic controllers and programming. To achieve this intent, Staff have prepared a Request for Proposals for Preliminary Engineering Services. The preliminary services will consist of evaluating the existing lift stations for capacity and property requirements in order to determine replacement priority, construction budgets, and construction phasing. With the preliminary evaluation completed, Staff will then request Design and Construction Phase Engineering Services necessary to complete the initial construction phase as identified in the preliminary evaluation. Current Project Status Responses to the RFP have been received and are under evaluation by staff. Project Timeline

• September 01, 2009 authorization to advertise the RFP. • September 22, 2009 Pre-Submittal meeting held. • October 09, 2009 responses received from seven (7) groups interested in the project.

Respondents included Bartlett & West, BG Consultants, Burns and McDonnell, Delich, Roth, and Goodwillie (DRG), Larkin Group, Olsson Associates, and Professional Engineering Consultants (PEC).

Project Funding These projects will be funded out of the 2009 Department of Utilities bonded construction fund per resolution No. 6835. Construction is anticipated to begin in 2010.

In addition, funds in the amount of $42,600 were placed in escrow by the developer of Sherylville Estates in 2005 to be applied toward the expansion of the sanitary sewer capacity provided to this area by pump station PS28. The expansion of sanitary sewer capacity to this area was included in the 2003 watewater master plan via the expansion of PS28 in 2009. This project is included in the scope of this RFP. The escrow agreement requires that the project be initiated and funds expended in 2009 or the escrowed amount be returned.

Current Project Status City staff have coordinated and completed the delivery of GIS and pump station run time data to Professional Engineering Consultants. City Staff met with PEC on January 6, 2010 to review pump station electrical and equipment requirements. Professional Engineering Consultants have completed the electrical review of the pump stations and are currently working to correlate calculated wastewater flow rates with pump station run time data to validate the basis of design flow rate. Based on project progress to date and discussions with Professional Engineering Consultants, City Staff anticipate the delivery of the initial basis of design report (BDR) by March 2010. This delivery schedule is consistent with the preliminary schedule set forth in the response to the RFP.

Topics of inquiry have included service area limits, existing and proposed flow conditions, methods of reconstruction, electrical supply and routing, site access improvements and requirements, as well as replacement priority. City staff completed and returned a questionnaire evaluating replacement priority at the request of PEC as a means of incorporating maintenance staff opinions and desires in the prioritization of the lift stations for replacement. PEC is also using replacement cost, criticality rankings, and maintenance data in order to develop the final replacement priority listing. Project progress has been consistent with the preliminary schedule set forth in the response to the RFP and City Staff will have the initial basis of design report May 07, 2010.
