Resolution to Approve Amendment No. 1 with Hubbell, Roth & Clark, Inc. for Construction Engineering Services at the Wastewater Treatment Plant ($20,532.00)
Memorandum
Your approval is requested for Amendment No. 1 to the Professional Services Agreement with Hubbell, Roth & Clark, Inc. (HRC) in the amount of $20,532.00 for construction engineering services for the Secondary Effluent Pump Replacement Project (SEPRP) at the City's Wastewater Treatment Plant (WWTP).
The SEPRP consists of replacing six secondary effluent pumps and associated electrical and control equipment at the WWTP. All six of these pumps are critical system components that were installed during the 1977 plant expansion, and each has a rated capacity of approximately 20 million gallons per day. These pumps transport wastewater from secondary (biological) to tertiary (sand filter) treatment, as well as enabling the plant to discharge final treated effluent to the Huron River when high flow conditions in the river prevent discharge by gravity. Over a four-year period, four of the secondary effluent pumps failed and required costly repairs. In addition, the remaining two pumps were functional but in a worn condition and at high risk of failure in a similar manner. Due to the nature of the failures, the criticality of the pumps and their poor condition, replacement of all six pumps was determined to be the most reliable and cost effective remedy.
On April 15, 2013, Council approved a Professional Services Agreement with HRC in the amount of $122,595.00 to design and prepare bid documents for construction of the SEPRP. Subsequently, Council approved contracts for the purchase and installation of six new pumps. On March 16, 2015, Council approved a Professional Service Agreement with HRC in the amount of $78,294.00 and a contingency in the amount of $8,000.00 to provide construction engineering services. As part of the agreement, HRC provided onsite construction inspectors, submittal re...
