AAA and 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)

2. Contents Introduction of AAA (Advanced Accelerator Association)
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.

3. Introduction of AAA AAA (established in 2008) is an organization of
Government-Industry-Academia
to invite and host ILC to Japan
AAA organization consists of four study groups;
(1) Technology
(2) Outreach
(3) CIVIL engineering
(4) Realization of Large-scale Project

5. Introduction of AAA
AAA vision is to advance in Science and Technology with the State of the Arts e+e- Collider Technology Development.
More than one hundred companies have participated to the general members of AAA and the number of institutional members is more than 40.

7. 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”

8. 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.

9. 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

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.)

10. 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

11. 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.

12. WG2 activity: Management of ILC civil engineering
