On Oct. 31, the IERC project achieved authorization for use and possession for the newly constructed building. This significant milestone, also known as substantial completion, allows for some access of the building for Fermilab groups to begin the transition to operations process. This also means that the vast majority of construction is complete, to the point that the building systems are operational and are in process of being commissioned. Construction is expected to continue through the end of 2022, including paving,…

The Wilson Hall north atrium canopy roof replacement project has begun. Scaffold erection is in progress, and the roof demolition and replacement process will follow. This project has been estimated to take three to four weeks for completion.

The Department of Energy has formally approved the start of full construction for the PIP-II project, an upgrade to the Fermilab accelerator complex that includes a new linear accelerator. PIP-II is an essential enhancement that will power the world’s most intense high-energy neutrino beam. It is the first particle accelerator built in the United States with significant contributions from international partners.
