DOD's fourth-quarter FY-18 report on MILCON bid savings, unobligated balances

The Defense Department's quarterly report sent to Congress in November 2018 states that at the end of fiscal year 2018, the Defense Department had about $12.4 billion in unobligated military construction money, meaning it had yet to be put under contract, though it had been requested by DOD and authorized by Congress for specific projects.
