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.

David Blaine – Electrified: One Million Volts Always On

David Blaine Electrified.JPG
Project Overview: 
Pier 54 in downtown New York City hosted David Blaine’s latest feat of magic and endurance. “Electrified: One Million Volts Always On” featured David standing for 72 hours in the center of 1 million volts of electrical energy via seven (7) Tesla Coils set to music. In partnership with Intel the public was able to control the volts of electricity and movements of the Tesla coils from Intel Ultrabook stations set up in New York, London, Beijing, Tokyo, and Sydney. Clad in a chain mail suit, Faraday cage helmet and steel soled boots, David Blaine stood atop an aluminum truss tower. He was the centerpiece of a truss assembly and spherical pipe globe provided by Pook, Diemont & Ohl and The Guild. To keep the weather from contributing even more danger to the event, StageCo erected a massive 65 foot by 75 foot steel roof structure with wind walls, installed from a barge crane in the Hudson River.
McLaren's Role: 
McLaren performed analysis on various features for the event as well as for the historic pier itself, working in association with Vice Media, the Guild, and StageCo. McLaren developed a High Wind Action Plan and advised the production regarding operational procedures. McLaren also analyzed a 33 foot 6 inch diameter by 41 foot tall custom truss structure, provided by James Thomas Engineering, for various environmental conditions; in addition to supporting the seven (7) Tesla Coils, the pipe sphere, and David Blaine himself. McLaren performed a peer review of the surrounding StageCo structure and engineered ballast configurations, to safely distribute the load of the 70 ton roof on the decaying 100 year old pier. McLaren also reviewed Steeldeck viewing platforms with LED monitors and analyzed the structural connections for the Tesla Coils, pipe sphere, and entry signage. Project challenges included: fast track job with ambitious goals, sign and scaffold designs and submission documents completed only days before event, and development of appropriate wind loads and operational procedures.
