AAA CIVIL Group Activity in Japan M. Yoshioka (Tohoku/Iwate Univ AAA CIVIL Group Activity in Japan M. Yoshioka (Tohoku/Iwate Univ.) on behalf of Y. Onishi (Chairperson, Professor Emeritus of Kyoto University, the leader of the Japan Society of Civil Engineers), and K. Takeuchi (Secretary, Senior Civil Engineer of OBAYASHI, one of the leading companies of civil engineering in Japan)

Contents Outline of the CIVIL Group and its Organization CIVIL Group Activity in 2016~ early 2017 four working group were organized to study various civil engineering issues. After making summary report for the above issues, new working groups were organized in early FY 2017. five working group were organized to support the site-specific civil engineering issues.

Outline of CIVIL Group Activity in Japan -The purpose of CIVIL Group and Organization- The purpose: to smoothly host ILC in Japan by investigating CIVIL-related design, construction and engineering works. The organization: when it was created in 2016 is consisting of four WGs by 30 companies of general contractors, geological survey consultants and others and creates following 4 working group: WG1: Important civil engineering issues of the ILC WG2: Management of civil engineering of the ILC WG3: Town planning when the ILC is located WG4: Research & Investigation for instance “on-site inspections”

The CIVIL Group Activities in FY 2016 6 reguler CIVIL Group meetings and 20 ad hoc WG meetings have been held including the presentation about the ILC basic policy by Prof. Yamashita of Univ. of Tokyo and Prof. Suzuki of Iwate Prefectural Univ. AAA CIVIL Group has displayed our activities and technologies of each company in LCWS2016 held in Morioka, Japan.

WG1 activity: Important issues 【Pick up following 4 important issues】 ① Strategic geological investigations for tunneling　 ② Hydro-geology investigations ③ Micro tremors in Detector Hall and BDS tunnel ④ Alignment 【The most important issue: Strategic geological investigations for underground construction】･･･we should ・ define three phase of designing & tunneling ・ define phase objectives and requirements for completing each phase Phase 1 Preliminary period Phase 2 The preparatory period Phase 3 Construction period 2016 2017 2018 2019 2020 2021 2022 2023 2024 2025 ~2030 Outline desin Basic design Detailed design and construction Project attract Construction contracts Various licensing Landowners negotiations Major civil engineering works completed Complete the outline design and estimate the construction cost -- Complete the basic design -- Detailed cost estimation -- Complete basic design of the ground facility -- Early confirmation of the detailed design -- Additional geological investigations -- Process adjustment with other works (utility, accelerator, etc.)

WG1 activity: Important issues 【Output examples】 　・ Geological investigations to be done in the pre-preparation period 　 Define issues during the outline design Point of interest during the basic design Survey items during Linac tunnel (1) Organization of conditions of the site to define the linac tunnel layout i: horizontal alignment ii: vertical alignment (2) Design of the standard cross section of the tunnel and shoring (3) Determination of the important conditions for the design and construction Geology, rock condition, underground water conditions (2) Fracture in thick earth covering zone (3) Weathering in thin earthe covering zone (4) Fracture and/or alteration zones (5) Geological boundary, river, railway, road, underground water Collection of ground information by ground survey and geophysical exploration (2) Study of specific survey methods i: Ground survey => Distribution terrain, geological nature, un- consolidated layer ii: Geophysical survey => Electromagnetic and elastic wave exploration Other underground construction Design the layout of access tunnel and access hall by considering construction method (2) Design the standard cross section and shoring Investigation a high priority zone

WG2 activity: Management of ILC civil engineering Recently, the Japanese MLIT (Ministry of Land, Infrastruｃture, Transportation and Tourism) published the new guideline 2015 for realizing a wide variety of bidding and contractual methods of public works. This enables to make the contracts of design & build, including detailed design, and early contractor involvement (ECI), considering its complexity, restricting conditions, client-side organization, and characteristics of contracts.

WG2 activity: Management of ILC civil engineering Selection of the Competition participants Method of selecting the successful bidder Method of payment Contract method Method to order only at construction sites General competitive bidding Price competition system The total value contract system Design-build system Comprehensive evaluation bid system Details with design work order Low price bidding control by Lump Sum Contract Designated competitive bidding Early contractor involvement Technology proposal and negotiation method Cost and fee contract and open-book method Method to order with maintenance and management Unit cost Quality settlement system Comprehensive ordering system Negotiated contract Step by step selection method Multi-year contract system

WG3 activity: Town planning considering sustainability and mobility A model of the guest house in Kitakami for short-, middle- and long-term stay for family and/or bachelor’s completely wooden using local woods and by local builders private sector (company) manages (business base) Zero emission This model house also can be used as a share house for the local elderly There is a huge demand in Japan Good and necessary business in Japan

WG3 activity: Town planning considering sustainability and mobility Plan view of the model house: 200m2 case You can modify the arrangement and size of the room as you need (like)

New Activities in FY 2017 Reorganization of CIVIL Group WGs to contribute more to host ILC in Japan New working groups were organized in FY 2017 to study following issues: WG1: Rationalization of underground structure itself WG2: Rationalization of underground structure design WG3: Rationalization of underground structure construction WG4: Town planning considering sustainability and mobility WG5: Safety and disaster prevention　　　　　　　　　　　　 Investigations of precedents: the existing accelerator-based laboratories and facilities in Japan and abroad KEKB, J-PARC, SPring8, SACLA, DESY, CERN
