Main Street paid parking nearing completion; council reviews concrete test results and mapping updates
Summary
Staff reported near-completion of Main Street compaction and parking installation but council reviewed concrete cracking, test results and a McGill recommendation to saw-cut and epoxy-fill cracks; council also asked staff to update utility maps after the project.
Town staff told council the Main Street paid-parking work is close to finished but that several related issues remain: a handful of parking spaces and concrete repairs, outstanding inspections and the need to update maps to reflect as-built conditions.
Staff said compaction and rock fill on the north side are complete and that the contractor was finishing the last areas on the east and west sides. "He's finishing up the last few golf carts now, parking," staff said, describing ongoing compaction and low-spot work.
Council raised concerns about spider cracks and testing. An engineer from McGill Associates (addressed in the meeting as Mr. Lipinski) explained the contractor is required to provide geotechnical testing and that early 7-day compression tests may show lower strength but the 28-day cure results met the contract standard (above 4,000 psi). Lipinski said he would obtain specific air-content and slump results for council review.
On repairs, staff and the consultant described a targeted approach: saw-cutting existing cracks and injecting an epoxy or polymer repair material approved by McGill rather than wholesale removal and replacement in every cracked slab. The consultant also said both projects carry an allowance in their bids (stated at $20,000–$30,000) that can be used for change orders; unused allowance funds are returned to the town.
Council asked that maps and asset records be updated when construction is complete so future projects do not run into the unknown undergrounds that have complicated this work. Staff agreed to finalize maps and post them online.
The council did not take a formal vote on the parking items; staff will continue inspections and coordinate final sign-off with McGill and the state as required.
