Langan Demolition

Since Langan’s earliest days, we recognized that demolition is an important component in the overall site design process. Accordingly, we embrace a comprehensive design approach that integrates opportunities for cost and schedule savings during the demolition to avoid duplicating activities during the construction phases. For example, reusing concrete/masonry material as backfill and selective foundation removal to accommodate new foundations and utilities saves on material disposal costs and avoids unnecessary excavation – each also resulting in time savings.  The firm’s long list of engineering excellence awards indicates our unique expertise in this area. We have worked on projects from razing single-family homes to mid-rise buildings in urban areas to complex, hundred-plus acre sites with millions of square feet of building demolition and salvage operations.

 

 

Giants Stadium Demolition

OVERVIEW
This project involved the demolition of the existing Giants Stadium, which was an 80,242-seat open-air stadium originally constructed in 1976. The project was challenged by poor subsurface conditions, numerous existing site utilities within the existing stadium footprint, presence of asbestos and hazardous materials within the stadium, proximity to the recently constructed MetLife Stadium, and the need to demolish the existing stadium while operating the new stadium and utility infrastructure that serves the Meadowlands Sports Complex.

Campbell Soup Company Corporate HQ Demolition

OVERVIEW
Langan was a part of the team joined to revitalize the abandoned, asbestos-filled Campbell Soup Factory. Langan was charged with the evaluation and remediation design of the contamination, the preparation of construction documents for the demolition of over 600,000 square feet using implosion methods, and the design of infrastructure improvements. Of the 150,000 tons of demolition rubble, all except 800 tons were reused at the site, resulting in a $3,000,000 cost savings. Today, a ballpark, amphitheater, office buildings and aquarium occupy this site.

Goldwater Hospital Demolition

OVERVIEW
The project consisted of the demolition of Goldwater Hospital, which is located near the southern end of Roosevelt Island, south of the Queensboro Bridge and north of Four Freedoms Park. The 12.5-acre site includes seven main buildings with interconnected corridors (215,000 SF), asphalt parking lots, and open space areas. Langan provided demolition engineering and regulatory permitting services, demolition documents consisting of drawings and specifications, and assisted the owner and contractor in preparation of the Stormwater Pollution Prevention Plan for the demolition work. One significant project challenge included coordinating only one single point of access to Roosevelt Island, which created difficulty for the removal of demolition debris and other materials from the site.
