On October 20, 2020, the City issued Invitation to Bid (ITB) 2021-012-WG for Routine and Emergency Services Pool of Prequalified Contractors to receive applications for prequalification from contractors.
At the February 10, 2021 Commission meeting, the Mayor and City Commission approved Invitation to Bid (ITB) 2021-012-WG (the “ITB”) for Routine and Emergency Services Pool of Prequalified Contractors to receive applications for prequalification from contractors.
At the December 8, 2021 Commission meeting, the Mayor and City Commission approved the award of a contract to the Stout Group, LLC (“Contractor”) pursuant to the ITB for rehabilitation of the 20-inch north and south water mains along the MacArthur Causeway Bridge (the “Contract”), in the total contract amount of $4,517,230.00, plus a 10% contingency, in the amount of $451,723.00, for a total contract amount of $4,968,953.00.
As the pipe replacement segments from the original scope of work were being executed, the Contractor, identified the need for additional replacement of pipe segments along the south water main adjacent to the west end; and further discovered that the mechanical joints (hardware and glands) along the south water main were in an extremely deteriorated condition, primarily due to excessive corrosion. The Contractor was able to make this discovery through an inspection conducted by a snooper truck, a method distinct from the original drone footage employed to develop the initial scope of work.
The Contractor has submitted a negotiated cost proposal, in the amount not-to-exceed $640,622.00, for the additional services, such as the replacement of 139 feet of pipe and a total of 78 mechanical joint rehabilitation, including hardware and/or gland replacements, along the south water main.
The Contract contains a contingency balance of $297,054.22, which may be applied to the cost of the additional work and services, reducing the total cost to $343,567.78 and thereby increasing the contract amount from $4,968,844.94 to $5,312,412.72.
The Public Works Department has reviewed the cost proposal and has determined it to be fair and reasonable, as such, the City Manager recommends approving the proposed change order, a copy of which is attached to the City Commission Memorandum accompanying this Resolution as Attachment B, in order to expeditiously complete this critical infrastructure restoration work.
