Task force reviews $5M dredging cost estimates amid rising project uncertainties

The Warner’s Pond Task Force Dredging Subgroup convened on December 4, 2024, to discuss critical updates regarding the dredging project for Warner’s Pond in Concord, Massachusetts. The meeting focused on reviewing cost estimates and their implications for the project’s future.

The subgroup began by examining the latest cost estimates, which revealed a base bid of approximately $5 million for dredging 35,000 cubic yards of material. Members expressed concern over the significant increase in the cost per cubic yard, which rose to $50, more than double initial expectations. This prompted discussions about the accuracy of the estimates and the potential need for further clarification from the contractor, Charter.

A key point of contention was the inclusion of a design escalation line item, which added a 10% buffer for unforeseen costs. Members debated the necessity of this escalation, questioning its relevance given the current stage of the project. The subgroup acknowledged that while contingencies are standard, the current estimates may not accurately reflect the final costs due to various uncertainties.

The conversation shifted to the implications of the high bid from Charter, which was deemed too expensive to be considered under best business practices. As a result, the subgroup discussed the possibility of issuing a Request for Qualifications (RFQ) to obtain additional cost estimates. However, it was noted that any new bids would need to follow a formal process due to the initial bid exceeding the budget threshold.

Members emphasized the importance of presenting the full scope of the project to the task force, including the high costs and the potential for alternative methods that could reduce expenses. The use of geo tubes for sediment control was highlighted as a particularly costly option, with one contractor suggesting that while they may be expensive upfront, they could save money in the long run by preventing maintenance issues.

As the meeting concluded, the subgroup agreed to take additional time to refine their proposal, ensuring that the updated cost estimates and project considerations are accurately reflected. The next steps will involve further discussions with the task force to determine the best path forward for the Warner’s Pond dredging project, balancing cost concerns with the project's long-term viability.
