Impact
Documented stable tilt and modest changes in building response through project closeout.
Challenge
Two neighboring buildings required monitoring during construction and load-transfer work for the Second Avenue Subway station entrance.
STRAAM approach
STRAAM monitored 301 East 69th Street and 1322 Second Avenue and issued a final report, #31, confirming sensor removal.
Result
Tilt remained stable and the buildings’ response changed modestly, giving the team a closeout reference.
