GSA's Public Buildings Service (PBS) is mandated by Congress to charge rent to tenants occupying space in owned and leased buildings.

The Spatial Data Management (SDM) Program is GSA’s national effort to create, update, and maintain its spatial data and associated Computer Aided Design (CAD) floor plans to accurately reflect the national federally owned inventory.

SDM CAD floor plans are the basis for the assignment data and square footage information that GSA uses for tenant rent bills. The creation and maintenance of drawings supports accurate rent bills for customer agencies.

The SDM program also aids in the performance and utilization of each asset while identifying the most efficient and cost-effective way to house federal employees.

The GSA Office of Portfolio Management provides national program support to the regional SDM programs through:

  • Implementing the PBS Business Space Assignment Policy
  • Maintaining SDM National Business Process Flows
  • Coordinating significant SDM projects

Regional SDM programs reinforce efficient management of GSA’s real estate portfolio. Asset managers, realty specialists, and property managers must have accurate inventory and assignment information through the regional SDM programs. The SDM drawings produced under the national program provide a graphic record of the GSA building inventory and can also be used as a planning tool and reference for building projects.
