Work continued to advance significantly on the Target Station (D02) . The fourth of five castings for the Monolith vault was completed even as wall forms and reinforcement are taking shape above the previously cast sections. Foundation works for the Transport / Administration area at the far end of the Target Station are also underway, including reinforcement and blinding. Target works will continue through the summer vacation period. A second major casting of the nine-metre-high Sprinkler Building (H10) walls was completed, leaving just inner walls and top slab before the building is weathertight and ready for installations in October. Final external piping is in progress on the Cryo-Compressor Building (G04) to accommodate the 19 helium tanks to be delivered over the second half of the year. Installation of the geo-membrane and soil topfill continue on the Green roof above the Accelerator tunnel (G01) .
