MOTION
Upon recommendation of Cheryl Porter, Chief Operating Officer - Water and Field Services, the Board of Directors (Board) of the Great Lakes Water Authority (GLWA), authorizes the Interim Chief Executive Officer (ICEO) to enter into Contract No. GLWA-CS-1747 Proposed Amendment No. 3 “Engineering Services for Fairview Sewage Pump Station Improvements” with Brown and Caldwell, LLC, with no increase in cost, for a total cost not to exceed $7,278,098.00 and an increased duration of 575 days for a total contract duration of 2,767 days; and authorizes the ICEO to take such other action as may be necessary to accomplish the intent of this vote.
BACKGROUND
GLWA Contract No. CS-1747 is a consulting engineering services contract providing design, construction administration and resident project representation (RPR) services related to capital improvements at the Fairview Sewage Pumping Station (Fairview Station) located in Detroit. Fairview Station was initially constructed in 1913 with upgrades in 1950 and 1998. The Fairview Station is a critical pumping station that lifts combined sewage flows into the Detroit River Interceptor (DRI) from several major upstream interceptors.
Construction improvements to Fairview Station are in progress and nearing completion under Contract No. CON-297. These improvements are primarily related to the pump house and the station’s ability to pump combined sewage into the DRI. The flooding associated with the unprecedented storm events of June and July 2021 resulted in a recommendation to rehabilitate the outfall sewers such that they can serve as an emergency discharge to the Detroit River under similar extreme rainfall events. The June and July 2021 storm events and recommended outfall improvements resulting from the events occurred after the execution of Contract No. CS-1747, and consequently the recommended outfall rehabilitation is not part of the original scope of Contract No. CS-1747.
This Amendment No. 3 proposes to extend Contract No. CS-1747 time by 575 days to allow for completion of the design of the outfall rehabilitation that will be constructed under Contract No. CON-297. Contract No. CS-1747 will provide design, construction administration and RPR services during this time as related to the outfall rehabilitation. Funds are available in the current Contract No. CS-1747 to execute this work. Consequently, this Amendment No. 3 is not requesting additional monies to complete the work.
Amendment No. 1 was due to the flooding events of June and July 2021, which caused the construction work at the Fairview Station to stop until the dry weather flows return back to normal. Due to the unforeseen conditions, re-design critical isolation improvements and re-sequence construction activities were required. This amendment increased time and cost for Project Management, Construction Administration Services, Resident Project Representative, Start-Up/Commissioning Services, and Provisional Allowance. Amendment No. 2 was a budget shift with verbiage only to the contract to provide additional design.
JUSTIFICATION
Completing the recommended outfall sewer rehabilitation is necessary to improve the sewer relief capability to the Detroit River. The Contract No. CON-297 contractor is mobilized, on-site and ready to complete the rehabilitation. Extending Contract No. CS-1747 by 575 days will allow design to be completed and further maintain continuity between the vendors of Contract Nos. CS-1747 and CON-297 such that construction of the sewer rehabilitation is completed timely, while meeting the quality requirements of the overall contract.
