The Target Station area (D02) geared up for some major work to be initiated in the coming weeks, including construction of the Monolith puck vault and the two-layer casting of the massive base slab for the Active Cells area. Two wall castings for the Monolith were completed along with reinforcement of the upper puck structure. Casting of base slabs in the Beamline Gallery (E02) moved forward, with completion of the 8,000 square metre slab expected in the next two weeks. Installation of large sliding gates in the Gallery Cold Box and Loading Hall (G02) began. And excavation and piping for the Sprinkler Building (H10) moved forward. This unique building is 9 metres high, 216 square metres, and will be cast completely in situ. It will hold 850 cubic metres of water and will be earthquake resistant.
