Japanese Research Team Borobudur Temple from 20 – 27 August 2013 Funded by the Federal Republic of Germany

As part of the ‘Second Stage Restoration/Conservation Work at the Borobudur Temple Compounds’ project, UNESCO – in close collaboration with the Borobudur Conservation Office – invited experts from Japan to undertake research to ensure its long-term preservation. This activity, starting from 20 to 27 August 2013, was made possible thanks to a continued generous contribution from the Federal Republic of Germany.

The objective of this mission was to continue the study of the state of structural security of the Borobudur Temple through the installation of technical monitoring equipment and collection and analysis of data in situ. The Japanese experts consisted of Dr Ichita Shimoda (Technical Advisor, Japanese Government Team for Safeguarding Angkor Monument), Dr. Mitsuharu Fukuda (Geotechnique expert from Taisei Geotechnique Co. Ltd.), Dr. Yoshinori Iwasaki (Geotechnique expert from Geo Research Institute, Japan), Dr. Tomohiro Masunari (GPS Surveyor expert, Morihara System Engineering Co.), and Mr. Kenji Uchida (Surveyor, Research Institute for Science and Engineering, Waseda University Japan). Dr. Shimoda has participated in previous research mission to mission in Borobudur in June and December 2012, also made possible through funding from the Federal Republic of Germany.

Throughout the eight-day research period, the Japanese team worked together with staff from the Ministry of Education and Culture’s Borobudur Conservation Office (BCO). Around ten staff took part from the BCO took part in the research activities in order to share their knowledge with the Japanese team, support in the collection of date, while also learning about the techniques and equipment utilized by the Japanese team.

The Japanese experts carried out a series of activities at the temple including:

  • Measurement of the reference points by Total Station in order to evaluate the previous movement after restoration work;
  • Installing eight inclination sensors at four locations on the temple;
  • Installing GPS equipment at four locations on the temple for long term displacement monitoring,
  • Installing water flow gauges and rain fall gauges in order to evaluate the drainage efficiency.

The staff from BCO will continue the monitoring of GPS, inclination sensors, water flow gauge and rain fall gage every week after the installation of this equipment. A further mission is planned for later in 2013 in order to work with the BCO to assess the data collected by the installed equipment and develop responses and recommendations in line with research results.
