THE 7th JOINT WORKSHOP AND BILATERAL OPEN SEMINARWERE SUCCESFULLY HELD IN BATAM, INDONESIA
According to the proposal from Indonesia side at the last 6th Work Shop( hereinafter,” WS”) inBandung, both side held a Bilateral Open Seminar on Long Span Bridge Technology( hereinafter,”the Seminar”) which will be a key issue for Indonesia in order to make the national land vision of6-axis Corridor come true in reality. This vision is also a part of ASEAN-connectivity. And fromJapan side, Tunnel construction technology was recommended to add to the seminar theme, for it isuseful and indispensable in the development of Indonesia and its vision.
The Seminar was delivered along with the 7th WS in BATAM, Indonesia where a long spanbridge project is on the way to the actual planning. In this 7th WS, both side picked up two themes
focused on;
1) Bridge maintenance research roadmap drafted in the 6th WS, and2) Tunnel and underground structure research roadmap revised in the 6th WS
In the Seminar, Prof.Yozo FUJINO, Tokyo Univ., Japan presented an excellent lecture in theGeneral Session which was on the Long Span Bridge with its technological history. Republic ofIndonesia and Japan are both island countries. And Especially in Indonesia so many long spanbridges will be needed to construct including Sunda-Strait. Both sides highly appreciated the lecture
as a mile stone for the technological cooperation between two countries to proceed fruitfully in thefuture.
Also in the Seminar, private sectors made presentations on durability of the bridge painting overthe sea and tunnel management on site in construction and maintenance. And an actual long spanbridge project in other area in the world was introduced for the reference.
1. 7th WS in BATAM
On 5th June, discussions of the cooperation on Bridge structure maintenance and relatedpresentations were delivered from both sides.
(1) Road map WS on Bridge MaintenanceOverload regulation and related system in Japan were presented, the non-structural measuresof which were showed as crucial part of the Bridge maintenance policy package in Japan. From
Indonesia side, on-going inspection system was showed in discussions, but it became clear for thedata with assessment not to be summarized into the report so far, and. And corrosions of the bridgestructure were showed as most hot issue in Indonesia.
And integrated meeting facilitated by international teams suggested that the result of theinspection assessment and the feature of deteriorations of bridge components in Indonesia should beshared till the next WS.
(2)Road map WS on Tunnel and Underground Structure
As to the cooperation of Tunnel and Underground Structure Research Project, Indonesia side
presented a trial research on numerical modeling and analysis of rock conditions for tunnel
construction in Indonesia. And from Japan side the auxiliary method and other relevant technologies
including quality control on site were introduced.
(3) Both sides discussed to issue research papers to the related conference held in the near future.

3. Next ACTIONSBoth sides reiterated the importance of the Interim WS planned in TSUKUBA, Japan at theend of this June to confirm and share the achievements at this stage. And the interim findings anddata should be submitted to the international conference like REAAA or other academic events togive messages to integrate third institutes into joining the cooperation.
As to the Long Span Bridge, Indonesia side revealed an intention of technological requests
being showed with actual projects in the near future. From Japan side, including participants fromprivate sectors, it would be welcome to serve further information requested by Indonesia side tosupport for mutual benefits. And the Second Seminar of Long Span Bridge was proposed as focusedon the Substructure, the technology of which is indispensable to the Sunda Strait Bridge located inthe sea.
