Over six days this past September, two new hutches were installed in the L0 experimental hall of Wilson Lab
 These new hutches are prototypes and a head start for the CHESS-U upgrade planned for summer 2018. The complete structure was pre-fabricated at ADC Inc. in Lansing, NY, and carefully disassembled and transported by CLASSE riggers to Wilson Lab. Preparations to the floor, involving steel and concrete fill over the existing utility trench, and cutting of a new door threshold, were completed just in time for the delivery of the first panels. Much planning resulted in us meeting the 6 day installation goal, proving that we can indeed meet the compressed installation schedule planned for summer 2018. The structure consists of co-joined hutches 1A3 and 2B. Hutch 1A3 is an extension hutch for the F2 station. It is being fully fitted out and will be commissioned in early February 2018. User experiments are already being scheduled. Once 1A3 is up and running, our focus will move to hutch 2B. Lighting, electric service and cable tray will be installed to get a jump start on summer construction tasks.
