Plaza 5 Harborside

OVERVIEW
Mack-Cali’s towering 35-story Plaza 5 Harborside has approximately 1 million SF of Class A Commercial space plus an additional 6 stories of garage parking to accommodate 1,283 spaces. Langan provided geotechnical engineering, site/civil engineering, surveying and a range of related services including landscape architecture, railroad (LRT) settlement monitoring and construction inspection. Special challenges were presented in the form of a deep foundation system consisting of both 200-ton concrete-filled steel pipe piles and 9-foot diameter concrete caissons socketed into bedrock to offset tower wind loads.
