NYSOGS 95 Walsh Retaining Wall

NYSOGS 95 Walsh (2).jpg
Project Overview: 
On March 11, 2015 a slope failure occurred that impacted a senior living building located at 95 Walsh Road causing the evacuation of the building. McLaren responded immediately that evening to observe the retaining wall and slope failure, which exposed a portion of the croton aqueduct built in the 1830’s.
McLaren's Role: 
McLaren determined the resulting slope failure was predominately mud, and excess water behind the wall appeared to have caused the failure. The main challenge was to not further destabilize the slope while stabilizing the remaining walls. McLaren recommended several next steps to the client. The ensuing effort, under an Executive Order from the Governor of NYS, was to design and construct a new 320 foot long tied back soldier pile wall with concrete form lined lagging in front of the existing stone gravity retaining wall as part of a Design-Build contract with Moretrench.

Battery Park Perimeter, Bikeway, Oval and Woodland Reconstruction

109455 Reconstruction of the Battery Park and Perimeter Bikeway 2015-06-12.JPG
Project Overview: 
The project reconstructed the path system in front of Castle Clinton to provide a great lawn with more open space. A bikeway was constructed along the north perimeter of the park that completed the linkage at the South Street Ferry with the West Street greenway.
McLaren's Role: 
McLaren provided full preliminary design and final contract documents for the completion of landscape areas and bikeway within the park, foundation design for the re-installation of 13 monuments, as well as permitting and construction administration services. McLaren provided Quennell Rothschild Partners with civil, geotechnical, structural, and other related services in connection with their New York City Department of Parks and Recreation contract to develop design and contract documents for the reconstruction of areas of Battery Park.

Teachers Village

Teacher's Village Building 6-245 Halsey Street.jpg
Project Overview: 
The Teacher’s Village at Four Corners is a $120 million workforce housing plan. That transformed four blocks into a village built around three charter schools and includes 224 homes marketed to educators.
McLaren's Role: 
McLaren provided geotechnical and structural engineering design services for 7 buildings (varying between 5- and 6-stories in height and cover approximately 79,000 square feet of building footprint area). For the borings, McLaren developed a plan and specifications for exploratory work and coordinated all activities of the drilling contractor, boring logs, and laboratory testing. McLaren prepared a geotechnical report and supervised pile driving and certification of records, including vibration monitoring and preconstruction surveys. McLaren provided comparative analysis of alternate framing schemes, developed a subsurface exploration plan, assisted in developing details for the curtain wall and facade system, designed foundations, provisioned sealed structural drawings, and provided the structural design of light gage metal framework (6-stories of load bearing walls that support precast plank ends and shear walls) for canopies and soffits.

Haverstraw Bay County Park - September 11th Memorial

Haverstraw 9-11 Memorial.JPG
Project Overview: 
Located where the Hudson River is its widest, at nearly four miles, this 34-acre park sits on the west bank of the river, and is composed of numerous interesting and popular components. The parks September 11th Memorial, serves as a commemorative tribute to the Rockland County natives who were affected by the terrorist attacks in 2001. It was the first in the region to open in 2003.
McLaren's Role: 
The memorial encompasses a serpentine walkway, bordered by stations of text displaying a timeline of the events that occurred on September 11, 2001. Central to the memorial is a 20-foot beam from Tower Two. This part of the memorial is set in one corner with an adjacent expanse of empty space, portraying loss. This area is angled upward to lead visitors to a corner wall, 20 feet on each side, exhibiting the names of the victims who either lived in or had close ties to Rockland County. Names are displayed in a random fashion, thus encouraging visitors to recognize each individual lost. Standing before the wall, visitors will have an open view of the waters of the Hudson River. Diagonally across from the beam stand three white monoliths symbolizing continued life beyond the expanse of emptiness. A circle of benches surrounds the monument and offers a view of the adjacent living Patriot Garden. The community of Rockland County donated much of the cost of this memorial. McLaren helped design and build this wonderful attribute to the park.

416 and 420 Kent Avenue

416 and 420 Kent Ave Rendering.jpg
Project Overview: 
416-420 Kent is comprised of 23-story towers, 6-story podiums, 1-level underground parking garages, residential units, commercial space, and amenity spaces on top of the podiums including swimming pools and outdoor basketball courts. The total constructed floor area is 800,000 square feet.
McLaren's Role: 
McLaren is providing full engineering design services for the structural, geotechnical, marine, and civil portions of the project. The 421a Tax Abatement deadlines created a need for a fast-track design schedule requiring a permit set of structural drawings to be submitted within a one (1) month timeline. Partial borings were expedited to facilitate a preliminary pile design required to submit a structural permit set. Internal coordination between the Structural, Marine, Civil, and Geotechnical Divisions at McLaren allowed the project to move at the fast pace required to meet the project deadlines.
