Defense Bill Authorizes Progressive Design-Build for Military Construction

The 2026 National Defense Authorization Act (NDAA) recently signed into law by President Donald Trump includes authorization of progressive design-build (PDB) for military construction.

It is the first time that the NDAA explicitly authorizes progressive design-build delivery for military projects. The provision establishes a clear framework for PDB, emphasizing qualifications-based, single-phase selection, and early collaboration between owners and industry partners.
