1) Overview (Facilty, Schedule, etc.) 2) BL1U (Layout, service/control infrastructure)3) Kicker and Septum 4) 1UB2 (vacuum box)5) Vacuum6) Diagnostics (1AUM5, 1UM6/1UBB2) 7) Timing monitor (1AUM4) 8) Shielding plug

• Alignment to ½ mm, especially our tilted 1BVB2 magnet and vacuum 'tubes' in the Septum Magnet. (BL)

• Paint blocks as well as floor? (Plant/BL)

• Plan to tilt the 1BVB2 magnet. (BL)

• Put in piping for cooling lines for Target and Liq D2O under shielding to

sub-basement. (Plant)

• Plan for 'hand-pack' around 1A and 1U 'plug' penetrations. Pre-fabricate pieces? (Plant)

• Understanding signal cabling in Vault/Tunnel (especially when it is attached to the ceiling or wall made of shielding blocks. Apparently this belongs to many different groups and not just Controls. (Diag/Vac/Safety/Controls)

• List of final tests to be done before “sealing up” 1A Tunnel.
