This building was inspected for the shell only as no other components within the building remained. All mechanical, electrical, plumbing, heating and insulation were removed. The exterior shell was inspected for cracks, settlement and erosion to mortar joints. Over the course 150 years, the adjacent building had taken it’s tole upon the three storey building. The roof of adjacent building drained into the mortar of the north and west sides. Over the course of time, the masonry had been loosened because of mortar deterioration.

Buildings should not have been this close to each other as drainage damaged the wall. Alternatively, the roof should have been redesigned to deflect water to the north and south sides complete with metal flashings on the grey building west wall.
Here are some samples of damages done by water and ice.

A temporary steel beam and column reinforcement has been installed to prevent collapse of the building, but at the time of inspection, there was actually mortar and stone falling off the building.

A drainage system was setup on adjacent building’s roof to deflect water to the north side onto a steel decking system but water was being pushed up to the stone wall. The stone has a bulge and crack and is ready to collapse momentarily.

Chimney mortar and stone completely deteriorated. Advised client to either cap off chimney or rebuild.

Parapet on top of roof shows deterioration and metal flashing completely corroded. Recommended to repair masonry of parapet complete with new flashing cap on parapet perimeter of building.
