Things to watch
- Serious: Most documents released only on request. You get the remaining solicitation documents only after confirming you will attend the November 17, 2026 site visit and pre-bid meeting.
- Worth checking: Site visit and pre-bid meeting on November 17, 2026. The notice ties document access to attending, though it does not say attendance is mandatory for an offer.
- Minor: Roofs over critical lab operations. Failure of these roofs would hurt top-priority experiments, so expect close scheduling and protection rules during work.
