Engineering and construction firm CDM Smith has asked Boston-based Margulies Perruzzi Architects (MPA) to design its new global headquarters in Boston.

CDM Smith is moving to a 120,000-square-foot space at 75 State St. from 50 Hampshire St. in Cambridge. MPA will design and renovate six floors at the State Street space under a tight eight-month schedule.

The new headquarters will feature an open plan setting, glass-front offices, conference rooms, huddle spaces, a design-build center, automation lab and a multi-purpose room for training and all-staff meetings. Overall, meeting space will be increased by more than 160 percent in the new headquarters.

The work areas will be built with prefabricated partitions for flexibility and easy reconfiguration, and sustainable materials will be selected to realize energy savings and efficiency and promote a healthy work environment.

Structure Tone is the general contractor for the project, and TMP Consulting Engineers is providing MEP consulting services.
