FRIB civil construction is still progressing swiftly. The tunnel and surface buildings are 10 weeks ahead of the baseline schedule, with a goal of starting installation of front-end equipment in November. The linear accelerator tunnel lids have been completed, and the surface-building exterior is rapidly developing as masonry, roofing, and metal panel installation take place.

On the west end of the tunnel lid, vertical ductbank shafts and formed piers are being installed, while backfilling continues in the target area. To date, backfill is 70-percent complete, with 56,250 tons placed so far.
