Taconic Bridges RDSA

Taconic Parkway Bridge Design Services
Project Overview: 
As part of a Design Services Agreement with the State, McLaren provided engineering services for the replacement and rehabilitation of a dozen bridges throughout Region 8. Among the bridges assigned under this agreement are the Taconic State Parkway over Angell Hill Road, in Columbia County, Route 6 over the West Branch of the Croton River, Route 121 over the Stone Hill River, Route 22 over Muscoot Reservoir and numerous bridges along 9A in Westchester County, and Route 9D in Putnam and Dutchess Counties. The Bruckneck Tunnel was also inspected and rehabilitated under this program.
McLaren's Role: 
McLaren provided Phases I-VI of the design services associated with the replacement of both of the Taconic State Parkway Bridges. Work involved removal of a three-span structure and replacement with a new single span bridge on an existing horizontal and vertical alignment. The proposed superstructure consisted of pre-stressed concrete arch beams with stone facing on the fascia. Other areas of involvement included M&PT, approach work, paving, pavement markers, striping and utilities, and guide railing.

Super Grid Collapse Analysis

Super Grid Load-Testing and Collapse
Project Overview: 
McLaren was asked by NJSEA to provide a third party review of the design drawings, supporting calculations, and computer models of the first Super Grid designed for the Boardwalk Hall. Based on the findings of the review, McLaren recommended the Super Grid be load tested prior to being put into service for the Miss America Pageant.
McLaren's Role: 
McLaren developed a load-testing program that was performed, revealing inadequacies in the truss system that resulted in a collapse of the grid structure. Fortunately, the collapse occurred during the load test, as it would have been catastrophic had it occurred while in service. McLaren also participated in the follow-up investigations of the collapse.

Super Bowl XXXVIII Halftime Show Stage

66 - Superbowl 38 Half-time Show (Erected Perfomer Truss).jpg
Project Overview: 
McLaren was tasked by MTV Networks to provide structural and mechanical engineering and design for the Halftime Show Stage.
McLaren's Role: 
McLaren provided structural and mechanical engineering design, analysis and review services for the portable staging used in the Halftime show. The show featured six curved steel trusses made from chrome-moly steel that supported banners and either dancers or lights. The centerpiece was a two-stage cable lift with a kabuki curtain used to reveal the star singer. The towers and lift were mounted to and supported by rolling stage carts. The six towers sat on pivot frames and were hauled up into place by manually operated rope rigging. Critical project parameters included fast-tracked design and construction, low total weight, small collapsed size for storage and transport, and rapid set-up time.

SUNY Maritime Rehabilitation of Campus Pier & Other Waterfront Structures

SUNY Maritime Marine Structures
Project Overview: 
McLaren is performing marine structures inspection, and rehabilitation and repair design for the SUNY Maritime Campus’ entire waterfront in Throgs Neck, New York. The project involves an in-depth inspection of the campus’ Main Pier and comparison to a previous cursory investigation to access the full extent of damage and deterioration.
McLaren's Role: 
McLaren performed a structural and load rating analysis of the Main Pier before extending it to accommodate the docking of an additional sea-faring vessel. We are also rehabilitating the 5,000 square foot deck and Pier structure to help prevent similar damages and deterioration in the future. McLaren also inspected the structural support members to the college’s Student Activity Building to fully assess the extent of deterioration. McLaren designed the replacement of the C channel whaler providing lateral support to the steel sheet piling, and designed the replacement timber bracing between the piles supporting the boat crane. McLaren designed the replacement of the timber bracing between the piles supporting the campus boat shed and re-point approximately 3,400 feet of the college’s seawall as well. McLaren is currently performing construction inspection services.

Stevens Institute of Technology

Stevens Institute of Technology
Project Overview: 
McLaren provided structural engineering services associated with the design of a new six-story academic building spanning 90,000 square feet. The new School of Technology Management was constructed using a moment-resisting steel framing system designed to resist both gravity and lateral forces. The floor deck consists of lightweight concrete slab over galvanized metal deck supported by composite steel beams and girders.
McLaren's Role: 
As structural engineer, McLaren was provided structural engineering and design of the steel framing and concrete floor deck.
