This presentation explores the structural design and construction of the 550 Washington overbuild atop the historic St. John’s Terminal in Manhattan. Entuitive evaluated the 1934 rail terminal’s capacity for an eight-story office addition and developed multiple lateral system options to meet an accelerated schedule complicated by the Covid-19 shutdown. After assessing cost, schedule, and constructability, the team selected a segmental precast post-tensioned concrete core, an approach adapted from bridge construction that would achieve both speed and architectural impact. The session will highlight the evaluation process, the specialized construction engineering required, and the logistics of erecting the core.
Presented by Barry Charnish, P.E., Entuitive
- Course will award 1.0 hours of continuing education for the live session only.
- Each series registration is per person.
- This will be available as a recording, with no PDH attached.
Please note: This webinar is part of the NCSEA Webinar Subscription; however, we ask that all individuals register to receive credit for the live event.
