2. CCS reference for Civil Engineer Works Existing Floor Start digging at x = 1403.37 y = 2300.38 z = 2441.40 Flat part at x = 1256.43 y = 2239.46 z = 2446.04 Old coordinates: x = 1256.43 y = 2239.46 z = 2449.53 H3 line AWAKE line

3. CCS reference for Civil Engineer Works From end of TT61: ~ 50 m line to plasma cell (tbc) 2° angle wrt floor surface (bending) Plasma cell entrance ~1 m below flat part (3 m underground) 10 m long plasma cell + 30 m drift before dump (1.4 m)  dump entrance 4.4 m underground 10 m long dump. In total: 100 m, 2° slope  Preliminary estimate at dump exit: x = ???? (tbd) y = 2139.50 z = 2443.24 It could be underestimated (to be recalculated after lattice design and matching )
