At PNNL, our core capabilities are divided among major departments that we refer to as Directorates within the Lab, focused on a specific area of scientific research or other function, with its own leadership team and dedicated budget.

Our directorates related to Mission Support & Operations include Office of General Counsel, Business Services, Communications and External Engagement, Operational Systems, Communications and Information Technology, and Performance Management. 

The Operational Systems Directorate (OSD) leads delivery of PNNL’s 10-year, $1.2 billion campus construction portfolio— the single largest construction and modernization effort in the Laboratory’s history. OSD oversees operations and facility services, maintenance, and infrastructure planning.  

A team of nearly 800 staff comprise OSD, spanning in a wide range of disciplines, including craftspeople, engineers, construction professionals, technicians, scientists, administrators, and specialists. Together, they ensure that PNNL’s assets, services, and OSD-led programs are managed and performing safely, securely, reliably, effectively, and efficiently. 

The directorate stewards more than $250 million in annual budget authority; managing more than 2.5 million square feet of facility space across two campuses; overseeing approximately 200 regulatory program areas; and executing a multi-million-dollar facility and infrastructure project portfolio.
