GILFORD — Repairs to Dock 3 in Glendale came just in time, according to the company in charge of the structural repairs.
Tobin Greer, owner and general manager of Ambrose Marine Construction of Meredith, said one of the concrete slabs that form the walkway had only one-half inch of support from the underlying wooden cap.
“The repairs were necessary,” Greer said. “All it would take would be getting hit by a boat for the slab to come crashing down. The town did the right thing in closing the dock.”
Divers from Appledore Marine Engineering discovered the problems during an underwater inspection of the Glendale Docks in late May. They found that the structural elements along the last 60 feet of Dock 3 had shifted from their assigned positions. The town stabilized that section and closed it off while seeking bids for the necessary repairs.
Greer said the shifted pilings threw off the rest of the underwater structure, putting the whole thing at risk.
“When we lifted the concrete off, the underlying wooden structure was going in all different directions,” he said. “This was in real critical condition.”
Ambrose Marine’s job, which got underway on Tuesday and is expected to be completed by the end of the day on Friday, was to straighten the pilings and put in all-new wooden supports with cross-bracing before putting the 20-foot concrete slabs back in place.
Divers from Winnipesaukee Island Services were assisting with the underwater work on Thursday. The job went smoothly, with nothing unexpected showing up, they said.
When the selectmen awarded the contract for the work, Ambrose had projected a starting date of July 10, but Greer said it was delayed by the timing of other jobs that required use of the barge.
“We’re very busy this time of year, but were happy to fit it in. We know how many people are dependent on these docks,” Greer said. “It would be nice to do it in the fall, when the water level is lower, but that would have kept the dock closed all summer.”
The work on Dock 3 also affects Dock 2 because the work barge is positioned between the two of them.
“The people have been very understanding of us taking up so much space,” Greer said.
Public Works Director Peter Nourse had asked for the May inspection, saying the town had made various repairs to the docks over the years, but had never done an underwater inspection. He hopes to do follow-up inspections every five years as part of a routine maintenance plan for the docks.
The other docks, including the rest of Dock 3, were found to be structurally sound during the May inspection, Nourse said.
Gilford selectmen authorized the use of up to $25,000 from capital reserve funds to make the repairs.
