Title
Resolution to Approve Amendment No. 2 to the Contract with Hubbell, Roth & Clark, Inc. for the Lift Station Replacement Project, RFP No. 18-35 ($149,455.00)
Memorandum
Your approval is requested for Amendment No. 2 to the Professional Services Agreement with Hubbell, Roth & Clark, Inc. (HRC) in the amount of $149,455.00 for construction engineering services related to the replacement of Astor and Franklin Lift Stations being performed for the City's Wastewater Treatment Plant (WWTP).
The City operates and maintains eight lift stations, which lift sewage from lower to higher elevations as needed to allow it to flow by gravity to the City's WWTP for treatment. An evaluation of all eight lift stations were performed during development of the 2004 WWTP Facilities Master Plan, which identified lift station deficiencies and estimated the useful remaining life of each station. As a result of this evaluation, two of the lift stations have been replaced and another has been identified for elimination. The remaining five lift stations have been in service for many years and have nearly expended their expected useful life.
On March 4, 2019, Council approved a Professional Services Agreement with HRC in the amount of $124,565.00 to design five replacement lift stations. Specifically, HRC evaluated each of the five lift stations, performed a condition assessment of the wet wells to determine if replacement or rehabilitation was necessary, identified alternatives for lift station replacements, recommended the best alternatives and designed the alternatives selected by the City for replacement of the five stations. In addition, HRC developed a detailed design bid package and an opinion of probable cost for each of the five lift stations to be replaced. Based on HRC's evaluation, Astor and Franklin LS's were selected as the first two stations to be replaced.
Subsequent to design, City staff requested a proposal from HRC for construction engineering services relat...
