About this file
This is Addendum #01 to Request for Bids #DES 2026-20, issued by the New Hampshire Geological Survey under the New Hampshire Department of Environmental Services for the Groundwater Level Monitoring Network 2026 Bedrock Monitoring Well Installation Project. The addendum modifies three critical elements of the original bid solicitation: it adds Pay Item 2.7 for "Haulage of Drilling Spoils" with unit pricing in dollars per cubic yard; revises the steel casing quantities for Site 5 - Franklin from 43 feet to 163 feet and for Site 8 - Walpole from 43 feet to 173 feet; and extends the project completion date from June 30, 2027 to September 30, 2027. The bid closing date remains May 7, 2026 at 2:30 PM. All changes specified in this addendum supersede previously submitted documents and must be included with bid submissions.
Bidders are required to acknowledge receipt of this addendum by signing and dating the document before submission. The contact for questions regarding the addendum is Michael Howley at the New Hampshire Geological Survey, reachable at 603-271-2876 or michael.w.howley@des.nh.gov.
