Boulder hit in Brattleboro pool project
BRATTLEBORO — A renovation project at the Living Memorial Park swimming pool will require an additional $10,000 after a boulder was hit during excavation at the site.
"Part of the job is lowering the main drain and connecting it through a new pipe outside the pool area then out into the pump house," Town Manager Peter Elwell said at a meeting Tuesday. "In the cutting of the channel at the bottom of the pool for where the new pipe would be laid, the contractor ran into granite underneath the ground."
The pool has been leaking water for years. Approximately three million gallons of water was lost this summer, or about 30,000 gallons a day, according to Recreation and Parks Director Carol Lolatte. Renovations are expected to improve structural issues.
GS Bolton's original $137,000 estimate for the first of four phases included upgrades to the perimeter wall below the gutter, re-welding of the gutter where the welds have failed, repairing expansion joints, and refinishing parts of the pool and repainting. But painting was taken out of the project during a meeting in August as the town could do that at a lower cost.
Project Manager Mark Mariano, of Weston & Sampson, said a section of the pool floor was being removed by GS Bolton on Sept. 14 when the rock was encountered.
A change order was requested by the two groups involved in the project. The plan involved chipping and removing a portion of the rock at a cost of about $4,300, and it was done before Tuesday's meeting when the Select Board was asked to approve of two new charges. Already having the equipment on site helped save money on the job.
Another change order for additional concrete work will address various structural cracks found on the floor of the pool by cutting the deck. This carries a price tag of approximately $9,000.
"The many years of paint have filled in the structural cracks and they were not visible during the inspection," Mariano stated. "Removing the failing grout and plaster under the gutter exposed how the mid-80s gutter was constructed. Previous contracts cut the wall down and attached the gutter to the top of the pool wall. The gutter was packed with grout and plaster, and concrete on the backside of the gutter. The previous contractor tied the gutter in with the deck."
Those two elements will be separated because in the winter, when the deck moves due to frost or settlement, the gutter is shifting too. That's "creating a void or separation where the gutter would constantly leak," according to Mariano.
Several small sections of the pool walls that are weakening and delaminating will be removed and repaired, Mariano said.
"With no contingency account to draw on, we also went looking for ways in which we might be able to save additional money someplace else in the job," said Elwell.
The contractor has agreed to a request to credit the town with $3,000 and the town will take care of preparing the pool before painting. That job too can be done by the town at a reduced cost.
Altogether, the new aspects of the project minus the credit come out to about $10,382.
