NYSDOT Bundled Bridges Design-Build

NYSDOT_Region 8 Bundled Bridges.jpg
Project Overview: 
McLaren in association with ECCO III Enterprises was awarded the $47 million New York State Department of Transportation Design-Build Contract 3 Project for six (6) bridges in Region 8 (Westchester and Orange Counties). The project includes one bridge rehabilitation, one superstructure replacement, four full replacements on existing alignment as well as highway approach work where required.
McLaren's Role: 
As part of this Design Build contract, McLaren is responsible for the overall engineering design and construction support services of six (6) bridges located in New York’s Orange and Westchester Counties. Several of the bridges are located in high-volume corridors where maintenance and protection of traffic and congestion management were of chief concern. The overall goal to the Project involved reducing traffic impacts to the greatest extent possible.

Long Island Expressway/Grand Central Parkway Bridge Replacement

LIE & GCP Bridge Replacement.jpg
Project Overview: 
This project involves the replacement and widening of three (3) 3-span bridges at the Long Island Expressway (LIE) and Grand Central Parkway (GCP) interchange. Each of the three (3) bridges carries LIE traffic over the GCP and GCP service roads. The replacement of the bridges and various approaches is taking place over six (6) construction phases; to maintain and protect the continuous flow of traffic on both the LIE and GCP mainlines, service roads, and access ramps.
McLaren's Role: 
McLaren developed the erection sequence and means/methods of construction for each of the six (6) phases of steel erection. For each phase, McLaren prepared a comprehensive submittal which detailed the step-by-step erection sequence and procedures and included the required supporting calculations and drawings; all in conformance with AASHTO, NYS Steel Construction Manual, NYS Bridge Design Manual, OSHA and standard industry safety practice.

Design and Construction Inspection for the Replacement of Oak Tree Road Bridge

Orangetown Oak Tree Road - Ribbon Cutting.JPG
Project Overview: 
McLaren received the 2015 Public Works Project of the Year by the American Public Works Association, New York Metropolitan Chapter. The project involved the preparation of preliminary and final designs, along with construction inspection services, for the replacement of this historic bridge, which was constructed in 1887 and encased in concrete in 1930.
McLaren's Role: 
McLaren provided full bridge design services for replacement of the Oak Tree Road Bridge, including development of alternatives, preliminary bridge plans, advance detail plans, contract documents, and cost estimates. McLaren also updated bridge inventory forms and coordinated with the various utilities that will be affected by the replacement. Design of the new bridge was dictated in large part by the hydraulic analysis that was performed beforehand. Also key to this project was consideration of the historical nature of the bridge and the Tappan area. Located just to the southeast of the Tappan Historic District, the Oak Tree Road Bridge is in close proximity of the DeWint House, a historic structure where George Washington is said to have stayed. McLaren designed the new bridge, its guide rail and sidewalks with the area’s historic fabric in mind.

Pedestrian Park Bridges - Diving Inspections & Hydrographic Survey

NYCDOT Pedestrian Bridge Diving Inspections & Fathometer Survey.jpg
Project Overview: 
McLaren Engineering Group provided bridge diving inspections and hydrographic surveys of nine (9) pedestrian bridges throughout the five (5) boroughs. Comprehensive inspection and survey reports were also prepared.
McLaren's Role: 
Under this agreement, the nine (9) bridges inspected and surveyed were as follows: Wards Island Pedestrian Bridge – is a steel PL girder bridge consisting of 10 spans and three SSUs; 163rd Street Pedestrian Bridge – is a steel rolled girder bridge consisting of 13 spans and three SSUs; Ocean Ave Pedestrian Bridge – is steel and timber rolled girder bridge consisting of 30 spans and 30 SSUs; West Footbridge – is a reinforced concrete with corrugated form bridge consisting of two (2) spans and three SSUs; East Footbridge – is a reinforced concrete with corrugated form bridge consisting of two (2) spans and three SSUs; Bridge Over Dam - is a concrete and masonry arch bridge consisting of one (1) span and two (2) SSUs; Flushing Meadow Park Road – is a concrete box beam bridge consisting of five (5) spans and five (5) SSUs; NR Boathouse Footbridge – is a steel rolled girder/PL girder arch bridge consisting of one span and two SSUs; Pedestrian Between 73rd Street & 74th Street – is a steel PL Girder consisting of two (2) spans and one (1) SSU.

Project Overview: 
The East Avenue Bridge is a single-span bridge supporting four main line railroad tracks, contiguous to the East Norwalk Train Station.
McLaren's Role: 
As Prime Consultant, McLaren was responsible for complete reconstruction design of the bridge including the replacement of the superstructure and replacement of the existing abutments for roadway widening. McLaren provided a preliminary engineering study of four (4) span/roadway width scenarios to minimize the depth of the structure in order to improve the vertical clearance beneath the bridge.
