An independent engineering inspection of portions of Scarborough High School has found that there are no significant structural problems, though several smaller problems were discovered that could affect the building’s lifespan, and may make it vulnerable to “hazardous weather events.”

The report adds further credence to the construction job being done at the school, said district Facilities Manager Norm Justice.

“I’m very confident with what the process has been,” he said, adding the review found “minimal” issues with the $27 million taxpayer-funded project expanding and renovating the high school.

Noting that the district spent $1.8 million on engineering already he wondered why the town wanted to spend more.

“To spend another $25,000 to second-guess the top architectural firm in the state always seemed a little ludicrous to me,” Justice said.

The inspection was conducted by Po-Shang Chen and Christian D’Annunzio, of Boston-based C and C Engineering at the request of the Code Enforcement Department. The review focused on 10 specific areas the code enforcement officers did not have the technical expertise to review.

No problems were found with three of the areas. Four of the areas in question could not be fully explored because there was not enough information. Three areas were found to be inconsistent with contract documents.

The seven “active concerns” – the three that were wrong and the four that could not be explored – will not lead to any type of structural deficiency, but could lead “to potential damage or reduced performance of the building,” said C and C’s report.

To ensure that these problems do not become expensive to repair in the future, the report recommends that the town of Scarborough in conjunction with the contractor, Pizzagalli Construction, and the designer, Harriman Associates, consider obtaining a long-term insurance policy that will cover any repairs that may be required in the future.

“In the interim, we strongly suggest regular maintenance of the high school,” the report states. “We also recommend increased frequency of building inspection in the areas of concern (at least one inspection each year); we strongly suggest additional inspection of areas of concern after hazardous weather events.”

The only immediate action recommended in the report was repairing some erection bolts in the gym area that has become loosened and rusted. The report recommended the bolts be tightened or removed, clean any rust or damaged areas and paint the areas.

Justice said the issue has already been repaired, which he said is one problem of conducting such a review while active construction is occurring.

Town Council Chairman Jeffrey Messer, who first raised concerns regarding the construction earlier this year, said there were “good, bad and ugly” aspects to the report.

He believes the school and town should insure the building against any future problems that may arise from the issues identified in the report.
