5M Development

Constructed in multiple phases over a decade, 5M is a mixed-use, residential, office, and arts community development spanning 4 acres at Fifth and Mission streets between SOMA and Mid-Market neighborhoods. Langan is providing engineering services from design through construction. We conducted a geotechnical investigation to evaluate soil and groundwater conditions and site seismicity and geologic hazards. Our environmental team completed a Phase I and Phase II Environmental Site Assessment (ESA).
