Langan & Mack-Cali

Langan provides an integrated mix of engineering and environmental consulting services in support of land development projects. Langan is the largest engineering and environmental consulting firm headquartered in New Jersey. 

The Langan & Mack-Cali teams have partnered on numerous projects throughout the US. Most notable are the teams collaborations on numerous buildings along the Harborside in Jersey City. These projects helped catapult the resurgence of new construction and development in Jersey City.

Harborside Financial Center

OVERVIEW
The Harborside Financial Center includes 6.4-million SF of office, retail and structured parking facilities located along the Hudson River waterfront. Langan has been responsible for the geotechnical, site/civil and landscape design of approximately 4 million-SF of Harborside. Langan also designed nearly one-half mile of waterfront walkway on an existing pier as well as 700 feet of a new two-level promenade.

Schwab Building/Plaza 10 Harborside

OVERVIEW
Mack-Cali has fully leased this 18-story building, with upwards of 500,000 SF of Class A Commercial office space, to Charles Schwab. Langan successfully resolved unique geotechnical engineering challenges by using an unusual foundation system, over 100 feet deep, consisting of 225-ton concrete-filled steel pipe piles and grouted rock-anchor tendons to counter wind-generated uplift forces. Langan provided full geotechnical engineering services during both design and construction phases, and also site/structural engineering services for adjacent park furnishings consisting of bleacher and bench seating, retaining walls, cheek-walls, free-standing walls, stairwells and steps.

Plaza 5 Harborside

OVERVIEW
Mack-Cali’s towering 35-story Plaza 5 Harborside has approximately 1 million SF of Class A Commercial space plus an additional 6 stories of garage parking to accommodate 1,283 spaces. Langan provided geotechnical engineering, site/civil engineering, surveying and a range of related services including landscape architecture, railroad (LRT) settlement monitoring and construction inspection. Special challenges were presented in the form of a deep foundation system consisting of both 200-ton concrete-filled steel pipe piles and 9-foot diameter concrete caissons socketed into bedrock to offset tower wind loads.

Plaza 4A Harborside

OVERVIEW
Langan provided full site/civil engineering and landscape architectural design for this significant downtown Jersey City project near the Hudson River Waterfront. This was the first of a series of major building projects at Harborside by Mack-Cali, and the ten-story building serves primarily as a parking garage for 1,500 spaces on the lower seven floors, thereby clearing the way for high-rise commercial office towers in previously existing commuter parking lots.

Harborside Promenade

OVERVIEW
The Harborside Promenade is 700 feet long and consists of a bi-level structure, with upper and lower walkways separated by a 30-inch vertical distance and a combined span 32 feet in width. The upper walkway is a concrete deck on concrete-filled steel pipe piles and is finished with decorative concrete pavers for an “urban” feel. The lower walkway is timber decking for a more “marine” experience atop wood pilings.

Kulik Park Esplanade

OVERVIEW
Langan was presented with highly unusual challenges in tackling the restoration of a failed 800-foot-long steel bulkhead for the Kulik Park Esplanade adjacent to the Schwab Building on the Hudson River waterfront. Langan’s preload program stabilized the sheeting to support the Hudson River Waterfront Walkway that was subsequently built.

Westchester Financial Center

OVERVIEW
The Westchester Financial Center consists of approximately 309,000 SF of existing Class A office space in downtown White Plains. Langan worked closely with the owner and architect to re-imagine this site in a much more pedestrian-friendly way. The main concept was to pull nature back into the concrete-heavy character of White Plains by incorporating ecological design. With this in mind, the streetscapes and 3-tier interior rooftop courtyards were designed using our concept of the Southern Taconic Ecological Precinct, or S.T.E.P. This unique design infuses the multi-level pedestrian space with an educational landscape that includes native species in varying layers of the local, southern New York landscape while creating an interactive outdoor office and café to enhance the office experience.

Sylvan Way Improvements

OVERVIEW
Langan provided site/civil engineering and landscape architecture services in support of upgrades and improvements to an aging office park campus undergoing a re-tenanting program. The campus features three buildings of Class-A office space totaling nearly 450,000 GSF in Northern New Jersey. Langan worked with the architect and owner to design site improvements that included entry renovations, additional outdoor circulation and gathering spaces and connectivity throughout the buildings and existing parking areas. Our landscape architects designed an associated path and plantings to create a pedestrian greenway connecting two of the three buildings. Our project scope also includes landscape design and finishes for an existing stormwater pond on the property.

South Westchester Executive Park

OVERVIEW
The design of this multi-use business park had to account for numerous physical constraints including numerous and erratic rock-out crops, extensive deposits of soft compressible soils in lowland areas, and high groundwater tables in certain portions of the property. The business park is sited on a 140-acre tract of land and when fully developed, will contain in excess of 1 million square feet of new buildings.

DMAVA Park and Hudson River Walkway

OVERVIEW
DMAVA Park and Hudson River Walkway is a public waterfront park offering sweeping views of Lower Manhattan and the New York Harbor, as well as the home of the historic Colgate Clock. This project responded to the environmental, historical, and recreational challenges of the property, specifically the movement of goods and cargo nearby and the historic migrations of people through nearby Ellis Island and the Statue of Liberty. Langan designed this project for the NJDEP, including 1,600 linear feet of waterfront walkways, a bulkhead and waterfront esplanade, a timber boardwalk, and a three-acre park along the Morris Canal Basin, across from Liberty State Park. Our sensitive approach to preservation and ecologically-based engineering helped interpret and magnify this history while reconnecting Jersey City to its waterfront.
