The 2021 Infrastructure Investment and Job Acts (IIJA) included the Build America, Buy America (BABA) Act that established new conditions for spending federal money on infrastructure. BABA stipulates that manufactured products and construction materials must be produced in the United States when federal funds are used to finance infrastructure projects. BABA expands previous legislation that required airfield infrastructure projects that used federal money, mostly Airport Improvement Program grants, to use products and materials produced domestically. However, the new BABA makes federal funds available for airport terminal projects beyond runway or taxiway projects.
ACRP LRD 50: Buy America Requirements for Federally Obligated Airports, produced by TRB's Airport Cooperative Research Program, updates ACRP Legal Research Digest 18: Buy America Requirements for Federally Funded Airports (2013) to include new requirements under the IIJA. The digest includes the application of the domestic content thresholds; available waivers, other exceptions, and their practical implications; and considerations for the management to achieve BABA compliance. The digest includes an appendix with a table that compares Buy America provisions in BABA in relation to prior legislation applicable to federal aviation projects and grant programs.
