As for “excavation speed”, Shaft: considered construction cycle time (based on actual record and Japanese standard of the past) Adit: Japanese standard basis

8. Cycle Time (for Shaft)

9. Japanese Standard (for Adit) (Shown in the GDE-CFS meeting on 13 October, 2011 at KEK)

10. Assumption of Cost Estimation
Cost estimation is calculated on the basis of the direct construction cost
Preparation work is excluded
Indirect cost is excluded
Adit
Japanese standard (Ministry of Land, Infrastructure, Transport and Tourism) is adopted
Already shown in the GDE-CFS meeting on 13 Oct, 2011 at KEK
Shaft
There is NOT a standard for cost estimation
Cycle time for excavation is considered by reference to a past record and Japanese standard

11. Japanese standard (Ministry of Land, Infrastructure, Transport and Tourism)

12. Unit cost for adit (Shown in the GDE-CFS meeting on 13 October, 2011 at KEK)
Unit cost for tunnel excavation

13. Example of equipments for Adit construction
Drilling by using Drill Jumbo
Mucking

14. Feature of cost constitution for shaft

15. Equipments (example) Muck Kibble Scaffold for shaft excavation
Concrete Kibble
Excavation platform
Hoisting machine
Operator control panel

16. Summary of comparison between shaft and adit
Construction speed is low, because excavation muck should be hove up to the ground surface, and equipments should be escaped from the face for the blast etc.
Equipment cost account for the most part of the total excavation cost
<Adit>
Construction speed is fast compared with shaft
Cost is low even if a certain amount of the tunnel length
