Our central shops include our Key Office that manages access control and keying systems;  metal shops that fabricate custom materials and support overall building maintenance, a Building Automation and Controls group that develops, operates and manages highly complex control systems for major building assets,  and a central mechanical shop that supports the Maintenance Regions and Utilities and performs major repairs and infrastructure project work.  Our central program managers provide technical support and oversight for our more critical and highly regulated activities, such as chilled water systems and water treatment, life safety systems, and elevators.
