Thorlabs, a New Jersey-based manufacturer of photonic tools and systems, constructed their new corporate headquarters that includes a new three-story 121,277-SF building. The 6-acre site is part of the Town of Newton-Sparta Avenue Redevelopment Plan. The long-abandoned former industrial site provided environmental constraints, which were managed by Langan’s Licensed Site Remediation Professionals. Natural resources and permitting services included obtaining freshwater wetland permits to fill an isolated wetland.
