Mission 106
The 149,000 sq ft building is a wood-framed superstructure constructed over a concrete podium. During construction, the project team observed water leaking through exterior walls.
Chicago, IL
Moment
Scope/Solutions
Constructed in 2016, Moment provides 540 apartments in Chicago’s Streeterville neighborhood. The forty-seven-story building features floor-to-ceiling windows arranged in a symmetrical pattern. Three years after the building opened to residents, property management personnel reported leaks and cracked glass in the exterior window walls. SGH investigated the water infiltration and glass breakage issues.
Our investigation focused on the high-rise building’s two primary facade elements: window walls with insulated glass units and aluminum framing installed between floors and metal panels at the lower floors and spandrel conditions. Highlights of work include:
- Reviewing existing construction documentation
- Investigating the condition of the exterior walls, including performing water testing to identify leakage paths and making observations of concealed conditions at exploratory openings
- Evaluating extracted glass samples in our laboratory and determining the glass broke due to the presence of nickel sulfide, which induced spontaneous fracture
- Reporting our findings to the owner, recommending remedial work, and consulting on contractor-led repairs
