Agenda • Budget • Resources • CSR 2 • Discussion S. Evrard, 05 -12 -2017 Project Board Meeting #2 2

Budget: Key figures Ct. C Budget breakdown as in APT (22590 k. CHF, 2017 figures) Other including Project Centralized Budget, 5318, 23 % Cooling and Ventilation, 3535, 16% Manpower Staff: 45 FTE. years FSU: 36 FTE. years Electrical systems, 3787, 17% Power converters, 5370, 24% Magnets, 2341, 10% Civil Engineering, 2241, 10% • 1 st. CSR identified a lack of 3 MCHF to stay within the entire project scope, including options • Cost to completion reduced by 1’ 246 k. CHF corresponding to the CVI 2017. The CVI was applied to uncommitted budget extracted on 17. 11. 2016 with the following rates : -7. 02% on 2017 and -4. 93% on the following years. (no price escalation reserve like for HL-LHC, LIU and NEUTPLAT) • Re-baselining and next budget update pending confirmation and updated costs of main expenditures (power converters, magnets, CE, EN/CV & EN/EL) • Next CSR will focus on the re-baseline exercise outcome S. Evrard, 05 -12 -2017 Project Board Meeting #2 3

Budget: re-baselining • Recent developments - some budget savings expected/some extra cost • New estimate for AC distribution (4 TFO 1, 25 MVA instead of 9 TFO 2 MVA) • New estimate for DC cabling (23 km Cu 1202/2402 needed instead of 80 km 4002) • Renovation of the demineralized water station: no need for additional cooling tower • Sirius power converters: budget will be refined after pre-series test at the end of 2017 • Civil Engineering extra cost after bid opening: to be addressed in today meeting • New budget estimates in progress (EL, CV, …) • Proposal to call a second CSR next year in March to assess possible budget shortfall in the light of updated figures. • The date of the next CSR will allow to be in line with the next MTP preparation.

Budget: how to deal with B. 157 refurbishment extra cost ? • The project suggests using its centralized budget (created according to CSR 1 recommendations) to cover the difference between current SMB WP budget and current refurbishment cost following IT. • Current SMB WP budget + Project Centralized Budget (PCB) > CE cost. • Effectively this has to be first accounted for an additional budget expenditure, until subsidies are provided and other cost savings are confirmed S. Evrard, 05 -12 -2017 Project Board Meeting #2 7

Budget: how to deal with B. 157 refurbishment extra cost ? Some reminders: • IPP proposal (EDMS 1591815) didn’t include roof exchange and removal of ceiling insulation (containing asbestos) 2. 3 PROPOSED LAYOUT The proposal concerns external and internal refurbishment works: • removal and replacement by good insulated cladding of asbestos elements (vertical and horizontal) on façade, • replacement of the full existing glazing by performant (updated thermic parameters) cladding and glazing, • replacement on the roof of the gutters and treatment of the existing leaks, • addition of insulation panels on the ceiling of the hall. • This last proposal was not approved by HSE as it is forbidden to cover or hide insulation containing asbestos. S. Evrard, 05 -12 -2017 Project Board Meeting #2 8

Budget: how to deal with B. 157 refurbishment extra cost ? • As a result, there are extra costs for roof exchange and ceiling insulation removal and disposal corresponding to scope increase in : • Civil engineering works (roof) • Asbestos treatment (removal and disposal of ceiling insulation) • Difficult to identify corresponding costs in contractor bid but difference between initial budget (2480 k. CHF) and current cost following IT (3336 k. CHF or 3459 k. CHF with options) is about 1 million CHF • “Corresponding” extra cost for the roof < 659 k which could be practically covered by OCEN subsidy • By considering the subsidy, this leads to an additional budget requirement of ~350 k requiring CERN approval. It is suggested to consider this for SMB central asbestos removal funding • Major energy savings thanks to the updated thermal insulation: first estimate > 250 k. CHF/year S. Evrard, 05 -12 -2017 Project Board Meeting #2 9

Budget: how to deal with B. 157 refurbishment extra cost ? • Last but not least, a 10 % margin has been included in the FC document • PROPOSAL FOR THE AWARD OF A CONTRACT FOR THE RENOVATION OF THE ENCLOSURE OF BUILDING 157 ON CERN’S MEYRIN SITE • The Finance Committee is invited to agree to the negotiation of a contract with the consortium DIMENSIONE – TIA SUISSE, the lowest bidder, for the renovation of the enclosure of Building 157 on CERN’s Meyrin site for a total amount of 2 515 911 euro, (2 906 380 Swiss francs), with an additional amount not exceeding 251 591 euro (290 638 Swiss francs) to cover possible increases in the actual quantities used, as measured on site, bringing the total to an amount not exceeding 2 767 502 euro (3 197 018 Swiss francs), not subject to revision • The project considers this margin as a precaution taken for the FC. At this stage (contract ordering), the project will not immobilize the corresponding budget. • It is even suggested that CERN covers the risk of possible additional expenditures encountered during the work S. Evrard, 05 -12 -2017 Project Board Meeting #2 10

(Missing) Resources • CSR 1 and PB 1 finding: the preparation and execution of these works during LS 2 are still problematic for a few groups. • Mitigation measures envisaged/implemented by the project: • New recruitment (CV, EA) or Mto. P to fund fellow/PJAS positions (ACE, STI, EA, EPC, MSC) • Staging activities: maintain T 8 operation for 2021 and T 9, T 10 & T 11 for 2022, meaning no Cloud run with beam in 2021. • Additional outsourcing (collaboration, students) • Anticipate some activities to YETS 2017: obsolete cable Identification and removal • Reduced scope of activity for some groups S. Evrard, 05 -12 -2017 Project Board Meeting #2 11

Electrical systems AC distribution: CDR completed 4 TFO 1. 25 MVA instead of 8 x 2 MVA currently DC cabling: 156 cables 23 km 1202 and 2402 Cu (instead of 1800 cables 4002 and 80 km today) voltage reduction versus cable lenght validated OF, signal & control cables: Cabling campaign 1000 cables for EN-EL and 400 cables for EN-EA S. Evrard, 05 -12 -2017 Present EN-EL resources are fully committed in LS 2 other priorities and detailed studies cannot be performed in 2018 or 2019 ! Bottleneck for EA renovation Project Board Meeting #2 14

CSR 2 -Motivations • Proposal to call a second CSR in March 2018 to assess possible budget shortfall in the light of updated figures. • The date of the next CSR will allow to be in line with the next MTP preparation. S. Evrard, 05 -12 -2017 Project Board Meeting #2 15

CSR 2 – CSR 1 follow-up CSR on December 8 th , 2016 https: //edms. cern. ch/document/1800482/1 • The project is still young and many work was done and progress was made. • The WBS at the higher levels is clear, but in some places the details are not yet clear. Decision to implement EVM harmonization of WBS, CET and GANTT üThe highest priority is to get a frozen layout and apertures. Done üThe project has to go for the “performance option” i. e new magnet design for certain families. Done • Prioritize all activities that are beyond the baseline such that a staging approach can be applied. In progress, re-baselining to be presented in CSR II • Some risk analysis were made, but there is no cost attached to them. Complete the risk analysis for the baseline activities and including safety systems. Follow-up in PS-CSAP in January’ 18, safety review in February’ 18, associated costs to be ready by next CSR • Clarify the missing resources issue. Still in progress, many solutions already found S. Evrard, 05 -12 -2017 Project Board Meeting #2 16

CSR 2 - mandate • Panel Members: Antti Onnela (EP-DT), Henric Wilkens (EP-ADE), Luigi Serio (EN-DHO), Luigi Scibile (SMB-SE), Sylvie Prodon (FAP-RPC), Jean-Philippe Tock (TE-MSC), Katy Foraz (ENACE) The panel members are kindly asked to assess whether: • The the project baseline is sufficiently well defined and complete. • The revised budget and cost to completion envelope are properly estimated. • The funding scheme proposed by the project team is realistic. • The monitoring tools in place are adequate to assess progress and levels of expenditure. • The man-power situation is adequate, especially considering the LS 2 period or if additional manpower options/requirements are to be considered. • The schedule for the manufacturing, the installation and the hardware commissioning is achievable in time for commissioning of the facility in Q 2/3 2021 and availability for physics as from 2021. What are the consequences of not meeting this deadline? • The risks on critical items are acceptable? Are they manageable with the available resources? S. Evrard, 05 -12 -2017 Project Board Meeting #2 17

Discussion: questions • Shall we accept the estimate CE extra cost ? What is the alternative ? • Civil engineering options (façade composition, gables, lower walls, sky domes): greenlight ? • Do we have to increase PCB (5 to 7… 10%) ? • Are additional possible project funded resources an effective option to explore for critical groups ? • CSR 2: mandate, schedule OK ? • Next Project Board meeting – schedule ? • AOB S.
