Langan provides an integrated mix of environmental, geotechnical, site/civil, and earthquake engineering services on a variety of projects in the Bay Area. We bring decades of experience supporting some of the most challenging projects in the area, including industrial, commercial, high-rise, mixed-use, and multi-family residential developments. From urban brownfield redevelopment to complex waterfront revitalization and from seismic retrofits for mission critical facilities to major infrastructure initiatives, our services yield measurable value to our clients’ projects.
