The construction in Pittsburgh is progressing rapidly! They are now digging out the trench for the dilution fridges, after drilling out the foundation. The trench will be 4 feet wide, but they are excavating a much larger area. The reason for that is the high field magnets that will be situated in the trench. The magnets can ‘quench’ if there are ferrous materials nearby, so the workers are removing steel posts from the foundation.

The next phase will be to form the trench by pouring concrete. Here is another snapshot of a mini-excavator.

Thanks for Wilson Architects for keeping me up to date with photos.
