Harriman’s civil and environmental engineering staff has broad experience in site engineering, environmental engineering, regulatory agency permitting, site selection, site planning and site master planning. Public and private sector civil site design experience includes municipal facilities, educational institutions, healthcare facilities, commercial and industrial development, and parks and recreational facilities.
Harriman combines the legacy of two design firms into an even stronger, more flexible and robust firm dedicated to enhancing the built and natural environment. Together we are a more comprehensive integrated, full-service practice in architecture, engineering, urban design, planning and landscape architecture. Harriman’s urban design and planning studio (formerly The Cecil Group) has a rich history of working on municipal projects in the Commonwealth of Massachusetts.
Harriman pursues creative partnerships to design relevant and innovative solutions to human needs. Our work is based on the belief that design is a collaborative human endeavor centered on knowledge, ingenuity, and beauty. Through practicing the art of architecture and the science of engineering, we create environments that honor context, embrace wisdom, and enhance well-being.
