The New NY Bridge: Overview of Approach & Main Span Design and Construction Progress Update

When: 5:30 PM - 8:00 PM WEDNESDAY, FEBRUARY 22

Where: At The Center   

Marco Buyson, PE was one of six Design Area Managers during the Design Phase of the New NY Bridge Project and is currently the Design Services During Construction (DSDC) Manager and Lead Bridge Project Engineer. He oversaw the delivery of design packages for the main span and bridge wide design units of the bridge. As the DSDC Manager, he manages all DSDC tasks in coordination with the Project Engineers, including Requests for Information, Shop Drawing Reviews, Notice of Design Changes, and As-Builts.

Michael J. Martello, PE was the Global Analysis task leader for the approach spans of the New NY Bridge Project and was in charge of furnishing a full analytical model of the 3-mile twin structure to perform a seismic analysis of the crossing. The model also served as the foundation for a 3D design model connected to an As-Built database for use in maintaining and operating the bridge over its 100 year lifetime. Michael also worked on the project through construction serving as Project Engineer for the Approach Spans during DSDC.

The New NY Bridge is a twin three-mile, 44 span bridge, which includes 350-foot nominal steel girder approach spans and twin-tower cable stayed structures with 1200-foot main spans. This presentation provides an overview of the project along with construction progress to date. It also provides an overview of isolation as a seismic design strategy and discusses the procedures and techniques that were implemented in the global structural analysis models of the twin structures. Additional discussion will cover how the large models were organized and created; tools used to develop the bridge geometry, unique bearing properties, foundation properties, and interaction between the approach and main spans; and how result data was shared with the superstructure and substructure design teams. The presentation will also discuss verification of results using two independent models: one using RM Bridge to perform a multi-modal response spectra analysis to develop seismic demands for design, the other using ADINA to perform a verification nonlinear time history analysis.
