Manhattan Waterfront Greenway – Harlem River

OVERVIEW
The $180M Manhattan Greenway – Harlem River project involves the assessment and design of structural repairs and reconstruction of over four miles of Harlem River bulkhead from East 125th Street to East 145th Street and East 155th Street to Swindler Cove. In addition, the project involves the design of a waterfront esplanade and park to connect and extend a continuous greenway across seven blocks along the Harlem River between East 125th and East 132nd Streets. Langan will be leading detailed site investigations that include boat-mounted laser scans of the bulkhead tied into upland surveys and extensive engineer-diver inspections.

Vario Redevelopment

OVERVIEW
Langan provided geotechnical and environmental engineering due diligence review services for proposed 2900-3060 Brighton Boulevard mixed-use redevelopment, Vario. The redevelopment of is part of a larger development of the rapidly growing section of Denver, Colorado known as River North Art District (RiNo). The redevelopment includes new construction, as well as renovations to several buildings. The project site consists of two adjacent parcels totaling approximately 7.8 acres. New construction will include over 400 apartments, nearly 100,000 SF of office space and 30,000 SF of retail space.

USciences – 1st Year Residence Hall

OVERVIEW
To better meet the needs of its students, University of the Sciences constructed a new, 126,000-SF mixed-use residence hall on the its main campus in the University City area of Philadelphia. The 426-bed residence hall for first-year students is a live-learn community that incorporates numerous sustainable features to achieve Green Globes building certification through the Green Building Initiative. To facilitate this new development, Langan designed the open-air plaza and streetscape on the neighboring streets and spearheaded the land-development permitting process with the City of Philadelphia agencies. The tight urban site, combined with substantial grade changes around the property, created complexity; especially with respect to the stormwater management and ADA accessible design.

Newark Liberty International Airport – ConRAC

OVERVIEW
A Consolidated Rent-A-Car (ConRAC) will be constructed as part of the Terminal One Redevelopment program at Newark Liberty International Airport. The new facility will have a footprint of 700,000 SF and include six levels of combined public parking and rental car operations, as well as a pedestrian connection to the adjacent AirTrain station. Langan is providing geotechnical and environmental engineering services to assist in evaluation of the project feasibility. Our geotechnical engineering services included development of a subsurface investigation program and preparation of a geotechnical report for the facility, including foundation design recommendations and seismic design parameters. Langan’s environmental services included development of an environmental sampling and testing program to support project estimates related to handling and disposal of soil and groundwater during construction.

Alameda Point – Buildings 9 and 91

OVERVIEW
When the Naval Air Station closed in 1997, the US Navy transferred over 500 acres to the City of Alameda. Most of Alameda Point has since been placed on the National Register of Historic Places and this area is now one of California’s largest historic districts. Buildings 9 and 91 are the first to be readapted for reuse. Langan conducted a subsurface investigation at Alameda Point. Selecting appropriate foundations for planned improvements at both buildings was critical given the presence of liquefiable soil and weak, highly compressible Bay Mud. Langan recommended a micropile foundation design to support a new mezzanine within the 96,000-SF steel-framed Building 9, which is supported on composite concrete and timber piles with a slab-on-grade floor that had settled several inches over time. The 51,000-SF Building 91, which is a wood-framed warehouse supported on spread footings, was strengthened to resist seismic loads with new shear walls or moment frames.

Columbus Magnet School

OVERVIEW
The city of Norwalk is currently securing approvals from CTDEEP to utilize a portion of the Springwood Park for the new Columbus School, a 66,000-SF, 480 student intra-district magnet school with a multi-purpose field, which will replace the existing Columbus School, located nearby. Langan provided engineering and land use permitting services to support project development and obtain necessary local and state approvals. Our team consulted with the project’s Landscape Architect regarding site layout, circulation and grading. Langan also provided survey services, including coordinating with a soil scientist to delineate the wetlands and preparing supporting materials detailing proposed mitigation measures to assist in receiving local Inland Wetlands and Watercourse Agency approval for the project. Additionally, we worked with the City of Norwalk to prepare mapping necessary for the land-swap associated with the relocation of Springwood Park to accommodate the new school and the City’s purchase of two additional properties in the northern portion of the site.
