The Annual FCC Week took place in London from June 5th to June 9th. The event had several members of the Civil Engineering team from the SCE department who contribute to the FCC Study, along with representatives from collaboration partners. Civil engineering plays a significant role in the cost of the FCC Lepton Collider and was discussed in the plenary sessions attended by over 300 participants. Tim Watson gave a well-received presentation on the current status of the civil engineering works.
A dedicated 1.5-hour session on civil engineering was held on June 7th, chaired by John Osborne. Three presentations were given during this session. Liam Bromiley from SCE/SAM/FS, in collaboration with Liliana Florez from the consultancy firm ILF, presented the current status of underground civil engineering for the FCC, focusing on baseline layouts. Liliana also discussed ILF's work on the schedule for the civil engineering works. The second presentation was delivered by colleagues from Fermilab who presented preliminary layouts for two FCC surface sites, highlighting the importance of international collaboration. The last presentation, by Roddy Cunningham from SCE/SAM/FS in collaboration with Lucy Rew from the QUANTUM consortium, covered the progress made on planned site investigations for confirming the FCC's feasibility. The call for tender for these investigations is set to be launched soon, with on-site work expected to begin in Spring 2024. Antoine Mayoux also contributed to the FCC Innovation Studies session on June 4th, presenting the results of initial environmental impact assessments at proposed site locations and how they influenced the refinement of drill site locations.
On the final day, Tim Watson summarized the civil engineering session for a broader audience and outlined the additional work that needs to be done by CERN's civil engineering team until the completion of the FCC Study by the end of 2025.
