During a routine building façade inspection, the company Wiss, Janney, Elstner, Associates discovered mortar was missing from a section of bricks on the Sawyer building, officials said.

Mortar was missing in an area near the seventh floor area of the building, which likely happened because of the winter’s cold weather, said Jim Wallace, the director of facilities. As a safety precaution, Suffolk Construction, the company working on the 20 Somerset building across the street, stretched mesh material across the problematic bricks and hoisted scaffolding in case anything were to fall off the building’s façade.

Wallace said nothing was imminently about to fall off the building.

Next week he is expecting to develop plans for repairing the building. An estimated cost for repairs is not yet clear, he said.

However, repairs will not be possible until the weather is warmer, said Wallace, who believes the university will wait until students have left for summer break in May to fix the bricks.

Façade inspections are required every five years by the city. Wallace said this inspection was on track with that requirement.
