This is Addendum #01 to Request for Bid (RFB) DES 2025-01 issued by the State of New Hampshire Department of Environmental Services in collaboration with the Lake Winnipesaukee Alliance (LWA). The addendum announces the cancellation of the original RFB invitation for the Implementation of Best Management Practices in Tuftonboro, New Hampshire, which targeted stormwater management and erosion control measures at Melvin Wharf Road to reduce polluted stormwater runoff and nutrient loading to Lake Winnipesaukee. The original scope of work included installing a trench drain to collect road runoff, constructing a bioretention area with plantings, creating a raised outlet with overflow pipe, and replacing an old buried culvert. The cancellation is effective immediately due to discovery of site conditions incompatible with construction as originally proposed in the bid. A mandatory pre-bid site meeting had been scheduled for March 31, 2025, at 10:00 AM, with sealed bid proposals originally due by 4:00 PM on April 18, 2025. The RFB will be reissued with revised information at a later date.

Interested contractors should direct inquiries to Pat Tarpey at ptarpey@winnipesaukee.org. The original project was partially funded through a grant from the New Hampshire Department of Environmental Services using Clean Water Act Section 319 funds from the US Environmental Protection Agency (EPA). The project timeline had anticipated substantial completion by October 1, 2025, with final completion and payment by December 1, 2025. Bidders should monitor for the reissued RFB with updated site conditions and project specifications before submitting proposals.
