Federal Real Property: Measuring Actual Office Space Costs Would Provide More Accurate Information, Report to the Committee on Transportation and Infrastructure, House of Representatives [open pdf - 1MB]
From the Highlights: "The government's RTF [Reduce the Footprint] policy has intensified federal efforts to reduce office space and save money since 2015. GSA [General Services Administration] and OMB [Office of Management and Budget] report key cost performance measures but questions exist about how well these measures reflect agencies' efforts. GAO [Government Accountability Office] was asked to review how federal real property costs have changed since 2015. This report examines (1) the extent to which performance measures reflect changes in civilian CFO [Chief Financial Officers] Act agencies' office space costs and (2) how selected agencies considered cost in their office space decisions."
