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.

East Avenue Bridge Design

East Ave Bridge.jpg
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.

Survey & Engineering Services, Quaspeck Park Drainage Improvements

Quaspeck Park Drainage.jpg
Project Overview: 
McLaren was retained by the Town of Clarkstown to provide surveying and site civil engineering services because several streets and adjacent resident lots in Valley Cottage were experiencing problems with both surface and subsurface drainage. Project locations included Charles Boulevard, Helene Road, Quaspeck Boulevard, East Mary Lane, West Mary Lane, and Rock Drive. To correct these deficiencies, modifications and improvements to the existing storm drain system were required.
McLaren's Role: 
McLaren’s surveying services included a boundary and limited topographic survey of four (4) parcels of land for the creation of drainage easements in favor of the Town of Clarkstown. The limited topographic survey included all utilities in the above-mentioned predefined area. Trees with a diameter greater than 8” within this predefined were located and mapped. Off-site drainage structures leading from NYS RT. 9W to Rockland Lake were also e located and mapped for Civil Design purposes. McLaren’s site/civil engineering services associated with this drainage improvement project included a site investigation, environmental assessment, hydraulic analysis, drainage analysis, drainage design, public outreach and construction administration.

Land Surveying Services: Central Park Westside Playgrounds

Central Park Picture.jpg
Project Overview: 
McLaren Engineering Group (McLaren) was retained by the Central Park Conservancy to provide services of a licensed land surveyor to develop topographic surveys for seven (7) playgrounds and adjacent landscape, located on the western perimeter of the park along Central Park West.
McLaren's Role: 
McLaren provided topographic surveys to support the Central Park Conservancy’s design projects for playgrounds on the west side of Central Park. The purpose of the surveys was to locate play equipment (posts at grade and structure outlines) pavement changes, walls, ramps, curbs, fences, benches, tree locations with diameter at breast height and base elevation, as well as locate visible utilities and incorporate data on subsurface utilities provided by CPC. For uses during design and construction, McLaren provided PK nails near each project area in accordance with NAD83 and oriented to Manhattan Borough north. L1/L2 GPS was used to create control points. Mapping of the surveys were produced in accordance with the Production Standards provided by CPC. After the data was gathered from the field, McLaren performed a comprehensive process to ensure the quality of our work, this includes L1/L2 GPS data post-process using OPUS; Horizontal and Vertical Datum calculations to bring in local control; and calculation reviews and approvals performed by a Senior Land Surveyor, and Final Mapping and Drafting reviews completed by a NYS Licensed Land Surveyor.

Grand Marais Harbor Restoration

Grand Marais Complete.jpg
Project Overview: 
The function of the Grand Marais Harbor of Refuge is to provide shelter for vessels that are caught in unexpected storms. A breakwater was constructed in the late 1800s as part of a federally funded project by the USACE. By the 1950s the pile dike breakwater had deteriorated and experienced substantial infilling with sandy sediment, reducing depths severely. Breakwater reconstruction consisted of a 1,550 linear foot (crest length) rubblemound benched breakwater constructed of quarried rock consisting of core stone, a layer of filter stone, and with a layer of armor stone covering the structure.
McLaren's Role: 
McLaren performed marine engineering and design services for the construction of a rubble-mound breakwater. The project involved an in-depth investigation of the harbors’ existing breakwater and review of available environmental reports and surveys to determine the characteristics of the harbor and the intended design. McLaren worked the Michigan Department of Environmental Quality (MDEQ) to ensure the efficient review and approval of permit documents during the permitting process. One of the main concerns McLaren had to address was the impact on the piping plover, a federally listed endangered species of bird. McLaren worked with the MDEQ and U.S. Fish & Wildlife Service to monitor the birds and gain approvals for the project. With the efforts of the community, the plover had their most successful breeding season on record. McLaren also developed final construction drawings in accordance with the USACE and reviewed the engineering behind all previously prepared design drawings. In addition to design work in the harbor, McLaren performed construction administration services including bid phase services, shop and installation drawing review, and construction observations for quality control. Schedule adherence for this project was imperative. The harbor was rapidly filling in with sand and work could only be performed in the summer, since ice floes prevent work in the winter.
