Explanation:
The Sanitary Sewer Lift Station W-14, located at 5596 Monroe Street, was installed in 1971 and most of the equipment and internal piping and valves at the station have reached their useful lives. On June 5, 2019, the City Commission authorized, via Resolution R-2019-161, the appropriate City officials to execute a contract with Southeastern Engineering Contractors, Inc. (“Contractor”) for construction services related to the rehabilitation of the Sanitary Sewer Lift Station W-14, in the amount of $2,395,072.00.
During construction, the Contractor experienced a number of unforeseen site conditions, including configuration, sizes and location of existing piping and valves that were significantly different than shown on the approved plans warranting re-design of the on-site force mains. As a result, the Contractor had to cancel the purchase of some ductile iron pipe fittings and order new pipe fittings. On May 14, 2020, the City Manager approved Change Order No. 1 in accordance with Section 38.48(B)(1) of the Procurement Code to extend the contract duration by 90 days.
Subsequently, several additional unforeseen conditions were discovered during construction including but not limited to changes to the configuration of the proposed off-site force main along South 56th Avenue and structural repairs of spalling and cracks in concrete structures such as walls, roof support beams, columns and window framing in the lift station building. In addition, the City determined it was necessary to change the vendor of the electrical equipment such as control panels and variable frequency drive (VFD) to expedite the project’s completion. Finally, there were delays in schedule for coordination with FDOT mobility project along 56th Avenue and due to COVID-19 pandemic.
The changes discussed above are necessary to complete the rehabilitation of the lift station. Contractor’s Change Order No. 2 includes a construction cost increase of $350,000.00 related to extended bypass pumping operation, changes in the sequence of work, delays, disruptions, re-scheduling, extended overhead, cost impact, and a time extension of 240 days.
On January 18, 2017, the City Commission authorized the execution of an authorization to proceed with Craven Thompson & Associates, Inc. via Resolution R-2017-015 to provide professional engineering services for the design, permitting, bidding, and construction services for the sanitary sewer lift station W-14 in the amount of $162,785.00.
On December 6, 2017, the City Commission approved and authorized Amendment No. 1 for Work Order No. CTA 17-01 with Craven Thompson & Associates, Inc. via Resolution R-2017-368 for professional engineering services for the design of flowmeter and bypass piping for Lift Station W-14, in the amount of $15,200.00.
Craven Thompson & Associates, Inc. submitted a proposal for professional engineering services related to the additional construction services for the unforeseen field conditions for the Lift Station W-14 project, in a lump sum amount of $181,570.40.
The Department of Public Utilities recommends that the City Commission authorize the appropriate City officials to execute the attached Change Order to Southeastern Engineering Contractors, Inc. to extend the contract time for an additional 240 days and increase the project cost in the amount of $350,000.00 to $2,745,072.00.
The Department of Public Utilities recommends that the City Commission authorize the appropriate City officials to execute the attached Amendment No. 2 to Work Order No. CTA 17-01 with Craven Thompson & Associates, Inc. for additional professional engineering services related to construction services for Lift Station W-14 project, in the lump sum amount of $181,570.40 for total aggregate cost of $359,555.40.
