Princeton University – Andlinger Center

OVERVIEW
Princeton University’s 129,000-SF Andlinger Center for Energy and the Environment provides new research and development facilities to students and teachers studying renewable and sustainable energy, climate change, and numerous disciplines related to energy efficiency and social/environmental economics. Langan’s geotechnical engineering services included conceptual design for the project’s support of excavation (SOE) and underpinning systems, specifications for SOE and related earthwork, and review of foundation systems. We also provided consulting services during the design development and construction documentation phases. The building was designed to meet LEED Silver requirements.

Tower at 4 PNC Plaza

OVERVIEW
The Tower at 4 PNC Plaza is 33 stories high and considered the world's most environmentally-friendly building. Langan developed caisson design parameters for the building based on field-load test data, test-drilling results, and available site-specific geotechnical information. Langan reviewed the subsurface and load-test data and developed caisson design parameters based on the data and our experience with similar structures. Our recommended design parameters led to a less-robust foundation system and considerable cost savings and schedule reductions. Design completion included full-time Langan observation during deep foundation construction.

Public Safety and Answering Center (PSAC) II

OVERVIEW
Langan provided multidiscipline engineering services for the development of a new 911 call center for the City of New York. The development included construction of a 10-story office building with a building footprint totaling 52,000 SF, a 25-foot-deep cellar, and approximately 34,545 SF of surface parking. The building is an essential facility, designed for category 4 hurricane wind and flood levels, seismic importance factor of 1.5, and fully loaded for security/blast attenuation/baffling. Langan provided a full range of geotechnical engineering services for the project, including subsurface exploration, driven pile and slurry (diaphragm) wall foundation design, site-specific seismic analyses including site-response analysis and liquefaction evaluation. Environmental engineering services included preparation of a Remedial Action Plan, Construction Health and Safety Plan, related construction documents, and coordination with the New York City Department of Environmental Protection.

Lyon Street Steps

OVERVIEW
Langan provided site/civil and geotechnical engineering services to support the ongoing reforestation efforts within the Presidio. Our team evaluated the stability of the existing Lyon Street retaining wall and the slopes behind and above the wall. The project involved a great deal of coordination among public agencies, regulatory agencies, and citizens since Lyon Street Steps is located on federal land and adjacent to private residential property.
