I. RECOMMENDATION:
Council Approval of an Engineering Support Task Order with the City Engineer as part of the approved La Questa Sewer Lift Station Pump Replacement and Power Supply Project.
II. BACKGROUND:
The Council authorized a project to improve the La Cuesta Lift Station located on the corner of La Cuesta Ave and Phelps Ave in the City of Coalinga, CA. The existing lift station currently has two Gorman- Rupp above grade self-priming pumps located within a removable housing. The housing is located within an open below grade sump which limits operator access. These pumps are beginning to fail and their reliability is diminishing.
The project will replace the existing pumps with solids handling submersible pumps within the existing wet well, provide an updated power supply, and controls. The 70-foot force main will also be replaced as part of the project. Improving the lift stations accessibility and safety will be included in the proposed improvements.
III. DISCUSSION:
MKN is currently sub-contact with the City Engineer to provide construction plans and technical specifications for the proposed lift station improvements including engineering services during construction. In addition to design services the City Engineer provides City Engineering support which is necessary to the project. A copy of the task order with detailed scope is attached.
IV. ALTERNATIVES:
None.
V. FISCAL IMPACT:
The City Engineer has put together a task order on a time and materials basis with a budget not to exceed $28,100. Therefore, staff is recommending approval of this task order in order for the City Engineer to provide support where anticipated during design and construction of the lift station improvements. There are sufficient project funds in the sewer fund to cover the cost of these services. | | |
