Washington and Main Street Intersection

Washington and Main Street Intersection
Project Overview: 
McLaren provided design services associated with the reconstruction of Washington and Main Streets in historic Tappan, New York including full in-depth pavement replacement, drainage design including utilities and right-of-way mapping, and roadway and sidewalk reconstruction. Public meetings were held to include the local community in the project and to collect input for use in the planning of the reconstruction, which included pavement replacement.
McLaren's Role: 
McLaren performed roadway design, including the preparation of detailed plans and specifications. The firm also performed utility coordination, public information meetings, traffic analysis, topographic survey, right-of-way mapping, and construction inspection.

Wallkill River Bridge Rehabilitation Design

Wallkill River Bridge
Project Overview: 
The Wallkill River Bridge is a six-span, concrete barrel arch bridge that carries Metro-North Railroad’s Port Jervis Line at Milepost 67.05 in Goshen, New York. Built in 1907, the bridge is approximately 381 feet in length with its superstructure consisting of concrete arch barrels supported on concrete abutments and piers and carries one railroad track over the Wallkill River.
McLaren's Role: 
A 2004 inspection of the bridge revealed a wide longitudinal crack on the underside of the bridge, a 24” sinkhole at the top of the deck, a clogged drainage system, severe scaling and spalling, and rotted track ties. McLaren has developed bridge rehabilitation designs based on the findings of this inspection as well of our own cursory inspection of the bridge that determined whether there were other significant conditions previously undiscovered. Various concrete repairs were designed, including repair or replacement of tile drains; removal of delaminated concrete; and repair of the longitudinal cracks. Waterproofing remedies were also developed.

Tina Turner 24-7 World Tour Stage

64 - Tina Turner 1.jpg
Project Overview: 
McLaren was tasked by The Mark Fisher Studio/Private Dancer Productions to provide structural and mechanical engineering services for Tina Turner’s “24/7 World Tour” Stage.
McLaren's Role: 
McLaren provided structural and mechanical analysis and design, dynamic analysis, details and periodic inspection for the Tour Stage. The design included custom staging and a signature boom lift. The lift consisted of a 54 foot long long-arm that rose out of the stage, pivoted over the audience, and translated across the stage with Tina Turner performing at the cantilevered end.

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.
