Title

Resolution to Approve Amendment No. 4 to the Professional Services Agreement with Hubbell, Roth & Clark, Inc. for the Lift Station Replacement Project, RFP No. 18-35 ($130,861.00 Amendment, $553,785.00 contract total)

Memorandum

Your approval is requested for Amendment No. 4 to the Professional Services Agreement with Hubbell, Roth & Clark, Inc. (HRC) in the amount of $130,861.00 for construction engineering services related to the replacement of Arbor Landing Sewage Lift Station (LS) being performed for the City’s Wastewater Treatment Plant (WWTP).

 

The City operates and maintains eight LS, 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 LS was performed during development of the 2004 WWTP Facilities Master Plan, which identified LS deficiencies and estimated the useful remaining life of each station. Two of the LS were replaced prior to 2015 and one LS, South Boulevard, is scheduled to be eliminated in FY 23.  The replacement of Sequoia No. 1 and Sequoia No. 2 Lift Stations are on-going and scheduled to be substantially complete by October 2022. 

 

On March 4, 2019, Council approved a Professional Services Agreement with HRC to perform the work described in RFP No. 18-35 to evaluate each of the five remaining LS for $124,565.00. Amendment No. 1 was authorized for $7,238.00 using the contingency on the original agreement bringing total design costs to $131,803.00. HRC performed a condition assessment of the wet wells to determine if replacement or rehabilitation was necessary, identified alternatives for LS replacements, recommended the best alternatives and designed the alternatives selected by the City for replacement of the five LS’s. In addition, HRC developed a detailed design bid package and an opinion of probable cost for each of the five LS to be replaced. Based on HRC’s evaluation, Astor and Franklin LS were selected as the first two stations to be replaced and were replaced in FY21.

 

On March 16, 2020, Council approved Amendment No. 2 to the Professional Services Agreement with HRC in the amount of $149,455.00 to perform the construction engineering services for replacement of Astor and Franklin LS.  On September 7, 2021, Council approved Amendment No. 3 to the Professional Services Agreement with HRC in the amount of $141,666.00 to perform the construction engineering services for the replacement of Sequoia No. 1 and Sequoia No. 2 Lift Stations, which is on schedule to be completed by October 2022.

 

The remaining LS, Arbor Landing, is to be replaced in FY23 as scheduled in the City of Ann Arbor Capital Improvements Plan.  As stated in RFP 18-35, City staff requested a proposal from HRC for construction engineering services related to replacement of Arbor Landing LS.  WWTP staff reviewed the proposed scope of services, schedule and fee submitted by HRC and determined they are reasonable.

 

WWTP staff is requesting your approval of Amendment No. 4 to the Professional Services Agreement with HRC in the amount of $130,861.00 and a contingency in the amount of $15,000.00 to fund additional necessary services as approved by the City Administrator. 

 

HRC complies with the City’s Conflict of Interest, Non-Discrimination, and Living Wage ordinances.

 

Budget/Fiscal Impact: Funds to finance the work to be performed under this contract are included in the approved Sewage Disposal Fund Capital Budget.
