4000 Massachusetts Avenue Masonry Repairs

Masonry repair services were provided for a 16-story, multi-family residential building with an enclosed six-level parking garage under the building. The exterior walls of the building have punched windows set in extruded aluminum frames supported on composite brick and concrete masonry unit (CMU)-block infill walls.

The project’s purpose was to restore the masonry façade deterioration, such as cracks and bulging masonry, due to the lack of vertical and horizontal relief joints. New steel shelf angles with flashing were installed at floor slab levels to provide new relief joints for future expansion and contraction of the face brick. Extensive areas of masonry were removed and replaced due to bulged brick areas which were becoming unstable.

The project scope also included masonry and limestone tuckpointing and repair, concrete steel column encasement repairs, installation of new steel shelf angles and flashing, window perimeter sealant removal and replacement, and window sill removal and replacement. Additionally, installation of new vertical control joints, remedial masonry ties and CMU backup wall removal and replacement was performed.
