Please include the following item on the City Commission Agenda for consideration at the July 17, 2012 meeting:
Set a bid date of August 14, 2012 for Bid No. B1238; Pump Station 15 Reconstruction project UT0919CS General Wastewater Pumping Station Improvements. Bid documents to be available Wednesday July 18, 2012.
Project Description:
The Department of Utilities budgets a yearly fund for the ongoing maintenance, repair, and, when necessary, replacement of existing wastewater pumping stations within the collection system.
Project Details:
The Department of Utilities 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 Department of Utilities will provide wet well level instrumentation, programmable logic controllers and programming.
To date the Department of Utilities has bid, awarded, and completed the reconstruction of pump stations included in Priority Group II including PS 12, 22, and 27. Priority Group I pump stations including PS 28, 35, and 37 have been bid, awarded, and construction commenced as of April 02, 2012. Priority Group I pump stations are to be completed and fully operational by August 30, 2012. Pump Station 15 was originally included as part of Priority Group I, but was separated from the group due to delays in property acquisition. Pump stations included as part of the General Wastewater Pumping Station Improvements are shown on the attached map.
Project Status:
Professional Engineering Consultants have completed the design and production of construction documents for pump station 15 reconstruction incorporating all City Staff comments on the plans and specifications. Final documents will be available for bidding by July 18, 2012. All property interests have been secured, required planning documents including annexation, zoning, plats, site plans, floodplain and special use permits have been completed and are expected to be approved as part of the July 2012 planning commission agenda. If planning commission approval is not granted, staff will request that the bid opening date be rescheduled to occur following final approval of all documents by the planning commission. All required state and local permits have been issued for the project.
Affected property owners will be contacted by City Staff prior to the start of construction to ascertain and address any concerns related to the project. A public meeting will be held for property owners impacted by construction activities following the award of the contract to introduce the contractor and City staff involved in the project, provide an overview of construction activities and projected schedule, and to address any concerns residents may have related to the project.
Project Schedule
The bid documents for the reconstruction of pump station 15 allow for 120 calendar days to attain substantial completion and 150 calendar days to attain final completion from the notice to proceed.
