FCC Civil Engineering John Osborne, Jo Stanyard, Matt Stuart(SMB - Site Engineering - FAS Section) Cost & schedule Phase 3 - specification 10th May 2017

Contents Alignment position update Cross-section and design updates Additional schedule constraints FCC-ee machine requirements FCC-eh machine requirements Surface updates Interaction point layout Geological investigation planning Spoil schedule Elliptical v circular shaft Shaft F options comparison Inclined access tunnels Mobile platform for installation of services Junction cavern evaluation 39th I&O meeting – 19-07-17

Alignment update 39th I&O meeting – 19-07-17 An order has already been placed with GADZ to provide more geotechnical information on areas where the tunnel passes through the moraines. 39th I&O meeting – 19-07-17

Cross-section and design updates Non-exhaustive list: Tunnel cross-section updates Beam dump design update Alcove number refined Partitions IR update 39th I&O meeting – 19-07-17

Phase 3 - considerations Additional schedule constraints Take FCC and SPS operational schedules into consideration Will an additional shaft near LHC connection be required for spoil removal? FCC-ee machine requirements Lattice file comparison under consideration, to be developed with integration FCC-eh machine requirements Under consideration at point L Drawings and specification under development Surface updates Some surface site updates pending, to be developed by integration Access to the sites to be evaluated and cost and schedule of any additional structures (roads, bridges, tunnels) to be included. Interaction point layout Consider variation where spacing between caverns is 10 m. FCC experimental point. 39th I&O meeting – 19-07-17

Phase 3 - considerations Geological investigation planning Next step for the project will be geological investigations Particularly interested in non-destructive testing Initial step is a plan with a cost and schedule estimate for investigations Spoil schedule A schedule is required for the quantity, type and shaft location of spoil produced during excavation. 39th I&O meeting – 19-07-17

Phase 3 - considerations Elliptical v circular shaft Which is more efficient in terms of cost and schedule for the 18 m magnet lowering shafts. Shaft F options comparison Shaft F is unacceptably deep, a reasonable alternative to a 12 m diameter vertical shaft is required Inclined access tunnels Positions still under assessment Work closely with the project schedule Two variations included in the specification Issue: Exceptionally deep shaft at point F Possible Solutions: Remove shaft and have a bypass tunnel Replace with a shaft of a smaller diameter Replace with an inclined access tunnel 39th I&O meeting – 19-07-17

Phase 3 - considerations Mobile platform for installation of services in shafts Examples from previous projects along with cost estimates. Junction cavern evaluation Dimensions of junction caverns to be revaluated to produce more streamlines baseline design. 39th I&O meeting – 19-07-17
