The 18-story residential building at 1120 N. Lakeshore Drive was constructed in the mid-1920s. Designed by Robert S. DeGolyer, the building incorporates a structural steel framework encased in concrete. The exterior façade consists of masonry and limestone, which is supported by horizontal shelf angles that are anchored to the interior structural steel system. The roof has large copper clad gables that enclose the mechanical penthouse areas.
In the spring of 2016, Berglund Construction was hired by the building for its Phased Façade Repairs and Window Replacement Project. The work scope included masonry repairs, sealant repairs and window replacement and repairs.
The masonry repair scope included significant rebuilding of the brick and limestone masonry façade, steel lintel / shelf angle replacement, tuckpointing at brick and limestone mortar joints, rout and seal crack masonry repairs, and “as-needed” limestone repairs or replacement.
The sealant repair scope included removal and replacement of sealant at the perimeter joints at all existing doors and windows to remain, as well as removal and replacement of sealant at various masonry conditions throughout the building.
The window replacement scope included replacing all wood windows from the 2nd to 18th floors. Select windows were excluded from the replacement scope, and these windows were repaired and painted.
Berglund has provided all the scaffold access on the building with five mast climbers and four swing stages. The work began in March of 2016 and will be complete by the end of the year.
