RE: Proposed Amendment No. 1
Contract No. 1802543
Rehabilitation of Ferric Chloride Feed System at PS-1 and Complex B Sludge Lines
Vendor: Hazen & Sawyer
MOTION
Upon recommendation of Navid Mehram, Chief Operating Officer - Wastewater Operating 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. 1802543 Proposed Amendment No. 1 “Rehabilitation of Ferric Chloride Feed System at PS-1 and Complex B Sludge Lines” with Hazen & Sawyer, with no increase in cost, for a total cost not to exceed $2,322,045.00, and an increased duration of 438 days for a total contract duration of 1,415 days; and authorizes the ICEO to take such other action as may be necessary to accomplish the intent of this vote.
BACKGROUND
Hazen & Sawyer was awarded the original contract with a start work date of May 22, 2019, for a total contract amount not to exceed $2,322,045.00 for a duration of 976 days. The main objective of the Hazen & Sawyer contract was to provide design and construction assistance services for a new Ferric Chloride feed system originating in PS-2 and PS-1, and rehabilitation of SCB-30 Thickened Waste Activated Sludge (TWAS) Line which conveys liquid sludge from Complex B to Complex A at WRRF. The current final completion date of contract 1802543 for Hazen & Sawyer’s engineering services is January 21, 2022.
On April 5, 2021, Weiss Construction, LLC was given the Notice to Proceed on the associated construction Contract No. 2002190, which is the contract to construct the design completed by Hazen & Sawyer described above. This construction contract (2002190) has a duration of 24 months, with an established final completion date of April 5, 2023.
JUSTIFICATION
A time extension is needed to provide the required engineering services for the remaining construction contract time associated with Contract No. 2002190, which is ongoing between PS-2 & PS-1, and Complex A & Complex B at WRRF.
Contract No. 2002190, which is the construction contract for the new Ferric Chloride feed system is expected to reach final completion by April 5, 2023. The contractual substantial completion date for Contract No. 2002190 is established as of October 5, 2022.
It is GLWA’s recommendation to extend the final completion date of Contract No. 1802543 from January 21, 2022, to April 5, 2023, to match the associated construction contract. Hazen & Sawyer submitted a time extension request and a zero-cost proposal to GLWA on April 5, 2021. No additional money is requested through Amendment No. 1.
