You classify it as strategic readiness and have something like a Core of Engineers do the work.

Really the US military forces need an additional branch, the Civilian Core of Engineers. They would be held to high ethical standards (on the job), and all work they do for the government would become public domain. I imagine this could be combined with a New New Deal where public-works projects are generally funded, as well as a job guarantee / internship place to build a resume and gain social connections through.
