Work to repair water-damaged siding and structural components on a portion of Lincolnville Central School will be bid out as soon as possible, with project completion slated for Nov. 1.

LCS Principal Paul Russo said the funds to pay for the repairs, estimated to cost around $145,000, can be withdrawn from a capital reserve fund with the school board's authorization.

"We should be able to cover the costs from that fund," he said. "That's what it's for."

The water damage was caused by the failure of the exterior Werzalit brand composite siding and improperly installed water barriers around 10 windows, according to a engineering report by Cordjia Capital Projects Group. Russo said there have been class action lawsuits in the past against the siding manufacturer.

Russo said the school's insurance company also performed an engineering study and is in agreement with Cordjia's findings. The insurance company will not cover the damage, he said, but determining who is responsible for the problems and recouping the cost of repairs are being explored.

"We have a good group of people supporting us in regard to next steps," he said.

The 31,715-square-foot, two-story school was built in 2005. While the construction is primarily brick masonry and steel, there are significant areas of composite wood siding. Oak Point Associates of Biddeford was the architect, and the general contractor was Bowman Constructors of Newport.

Russo said the same siding on other exterior walls of the building has been inspected and is not showing deterioration. A lot of water comes off the gym roof, he said, and there is not a lot of roof overhang in the area where the siding deteriorated. In areas where there is a lot of overhang, the siding is not failing, he said.

The extent of the damage was discovered after the school hired Cordjia to investigate replacement of a section of exterior siding on part of the gymnasium wall that appeared to be deteriorating. The LCS Committee authorized a repair of the siding in 2010, but the problem worsened.

Cordjia conducted a study of water damage to the siding and structural components along a 102-foot wall located under the upper gymnasium roof, windows in the wall, and the metal roof below the wall that extends over the locker rooms and toilets. Siding, metal roofing material and a window were removed in order to further examine the damage. In addition, a high-tech method called "neutron moderation" was used to detect moisture under the metal roof, which is 117 feet long and about 15 feet deep.

Underneath the wall siding and metal roofing are structural insulated panels or SIPS, which are made of two layers of OSB (oriented strand board) with a core of polystyrene foam sandwiched in between. A typical SIPS panel is 8-inches thick and 4-feet wide by 8-, 10-, or 12-feet long. A second layer of OSB was nailed to the outside layer of the SIPS panels.

The investigation found "water damage far greater than anticipated," according to the report. The findings included disintegrating siding, spongy and disintegrating OSB beneath the siding, and moisture saturation and crumbling on the outer layer of OSB on the SIPS panels. It also found moisture saturation on the surface of the polystryrene foam inside the SIPS panels and rotting wood studs.

The use of neutron moderation technology further detected moisture damage that had completely deteriorated wood blocking supporting the wall SIPS panels and the exterior layer of OSB on the roof SIPS panels within 2 feet of the wall. High levels of moisture were detected along the length of the roof, as far as 5 feet from the wall, and even dry OSB 7.5 feet from the wall showed evidence of prior water infiltration.

The Cordijia report also questioned the underlying construction of the wall, including the structural components supporting the wall, and the attachment of the OSB sheathing and SIPS panels to the building's steel structure.

The windows were installed directly into the OSB rough opening without a weather barrier first being installed, according to the report. The weather barrier was placed after the window installation and was not sealed, which allowed water to enter the structure at the window perimeters, and possibly trapped water within the weather barrier, according to the report.

The wall repair calls for removal of 867-square-feet of siding, weather barriers, OSB, and 6.5-inch-thick SIPS wall panels. The wall will be rebuilt with a new metal stud wall, new blocking to support the wall, and new insulation, moisture guard and ventilation.

The roof repair calls for removal and replacement of approximately 1,880-square-feet of standing seam metal roofing with associated flashing and trims, and 624-square-feet of 8-inch thick SIPS roof panels. The roof will be rebuilt with new flashing, trim and ventilation.

Lincolnville Central School has a capital reserve fund that is held in a town account. The school committee is charged with determining how the money is spent, according to Russo, while the town signs the checks. On July 10, school committee members attended the Board of Selectmen meeting to provide information on the problem and repair work needed, according to Russo.

The school committee has asked Cordjia to put together design and bid specifications and Cordjia will pre-qualify the bidders, according to Russo.

"We have a strong and long-working relationship with them," he said. "Our goal is to have this work completed by the first of November."

The construction should only affect use of the locker rooms, Russo said, and should not impact use of the gym.

Russo said administration, staff, school committee members and building committee members keep an eye on the condition of the building, and will continue to do so.

"We take great pride in the building," he said. "We're very disappointed that this happened, and we're going to fix it and bring it back to the condition the people of Lincolnville believe it should be."
