Planning to Move Piers on Two 100-Year-Old Rail Bridges

Rasmin Kharva, PE, Lead Structural Engineer – H&H 

Richard Stevens, PE Structural Engineer – H&H

The Long Island Railroad “Double Deck” and “Mainline 1/3” bridges carry twelve tracks over the Van Wyck Expressway – a busy corridor leading to JFK airport in Queens, New York. The bridges were originally constructed in the 1910s and were lengthened with additional spans in the 1950s to accommodate the widening of the expressway. Recently, NYSDOT set out to construct two new multi-use lanes on the Van Wyck Expressway, requiring relocation of the lower portion of three column lines supporting this multi-level structure. For the Double Deck, a complex rehabilitation and load path reconfiguration scheme was developed, preserving much of the existing upper level of the structure to minimize long term impacts to commuter service. For Mainline 1/3, a bold roll-in replacement scheme was developed, aimed at replacing large portions of the bridge during weekend track outages.

Hydrodemolition and Latex Modified Concrete Overlay use in the United States

Ed Liberati, PE, Specialty Company Engineer – Hydro-Technologies 

This presentation will include detailed discussions on bridge deck preservation, bridge deck rehabilitation design and selecting the right bridge decks for Shallow Concrete Overlays. We will also cover the NYSDOT's 30+ year history with Latex Modified Concrete (LMC) Overlay use. Hyrodemolition and LMC science and construction will both be part of the session presented through pictures and videos of recent and past NYSDOT LMC projects including a detailed video of a project that was completed in Amsterdam in 2022. Unique Hydrodemolition applications will also be shared.

Building Asset Management into the ITS Design and Construction Process

Matt Davis, PE, PTOE, ITS Practice Lead – Stantec

John Hartley, PE, PTOE - Stantec

ITS system infrastructure is often modified over its lifetime by on-going maintenance activities, construction related incidents (i.e., fiber breaks and relocations) and/or system expansion, but detailed system records are oftentimes outdated, incomplete, or altogether lacking. Whether it’s field device information, fiber optic backbone splice locations and configurations, TMC schematics, cabinet power source information and/or simply conduit and pullbox locations, this information is critical in maintaining and modifying these systems over their lifetime. To facilitate Long-Term success of the system and reduce costs during any future expansions or upgrades it is critical to build into the design/construction support process the creation of a detailed GIS-based asset database that can be easily updated and managed over the lifetime of the system.
