Langan Engineering & Environmental Services
Langan Engineering & Environmental Services was established in 1970 by Bernard F. Langan in New Jersey. The firm began by providing geotechnical testing and foundation engineering to local developers, growing organically through recurring mandates from real estate owners who valued its dual competency in civil engineering and environmental science. The firm remains privately held with its headquarters in Parsippany, New Jersey. Langan's practice spans geotechnical engineering, environmental site assessment, remediation system design, natural resources permitting, and landscape architecture. Clients include institutional developers, REITs, public agencies, and energy infrastructure operators. The firm has executed site-characterization and clean-up programs at former industrial parcels now home to large-scale logistics centers and mixed-use projects across the Northeast and Mid-Atlantic. Its work supports transactional due diligence, where Phase I and Phase II environmental site assessments often gate acquisition closings, and it has designed stormwater management and coastal resilience infrastructure in the New York metro area. Langan employs engineers, geologists, hydrogeologists, and environmental scientists across offices primarily in the Eastern United States. The firm's practice model ties together civil site design with environmental compliance — a pairing that reduces coordination friction for clients navigating municipal land-use boards. Its project history includes brownfield redevelopments in New Jersey's Gold Coast and foundation engineering for mid-rise commercial structures along the I-95 corridor. Langan's structural differentiator is its multidisciplinary integration of geotechnical, environmental, and civil engineering under a single partnership, a configuration that allows a single team to manage the subsurface uncertainty, regulatory permitting, and site-civil design phases of a development without the handoffs typical of multi-firm consultant consortiums.
