1 Japan and Recamation Engineering Association

2 Purpose of JDREA Japan and Recamation Engineering Association (JDREA), a non-profit organization consists of 27 members, was founded in 1961 for the purpose of: improving the technoogies reated to construction of port and harbor faciities incuding coasta and offshore structures; promoting sustainabe deveopment of marine construction industry; improving the quaity of ife of the peope and secure their safety In order to reaize these, JDREA members have been continuousy deveoping advanced technoogies through acquired extensive and nurturing experiences in marine civi engineering fied, such as port and harbor faciities and offshore airport structures. JDREA aso aims to create a prosperous society by promoting marine civi engineering projects through research and deveopment of advance engineering and construction techniques, contractua approach, safe work, disaster prevention, environmenta conservation and internationa cooperation for deveopment. In addition, JDREA takes part in activities as a member of Japan branch of The Word Association for Waterborne Transport Infrastructure (IAPH) and The Internationa Association of Ports and Harbors (PIANC). Internationa Cooperation JDREA is firmy committed to contribute its technica advancements internationay and thus, aggressivey focusing on the foowing activities: Providing training courses for the engineers from recipient countries to introduce Japan s port construction technoogies under the sponsorship of Japan Internationa Cooperation Agency (JICA) Assisting the Ministry of Land, Infrastructure, Transport and Tourism in the introduction of Design Standard for Port and Harbor Faciities in Japan to recipient countries Transferring of technica know-howto the oca engineers through overseas projects of the member companies During a Lecture of JICA Training Course Trainees of Construction Site Observation

In order to utiize the artificia isand earier, soi improvement technique such as compacting and stabiizing soi is a key to shorten the project. Various techniques were used for the construction of airport isands in Japan to overcome such strict conditions as deep water, soft ground and arge scae rapid construction. Sand compaction pie method, vibrating compaction method and dynamic consoidation method etc. were adopted by JDREA contractors. Furthermore, the sophisticated settement controing system to measure the ground settement and deformation were introduced in these artificia isand projects. Therefore, these airports have been the best of the artificia isands in terms of scae and technoogy. Deep-sea treatment barge The improvement of quay depth at Tokyo Port, Yokohama Port and Kobe Port is necessary under minimized construction period to accommodate the increasing size of container ships. The adoption of technoogy such as improvement of soft seabed, instaation of stee ce and stee jacket was competey a construction time saving that extremey shorten the construction period. Inand disposa of surpus sois from construction sites is becoming difficut due to environmenta issue and imited dumping sites. Therefore, effective utiization of surpus sois for recamation work is usefu because it provides aternative disposa site in offshore with efficient containment and environmenta friendy. Sand compaction ship Environmenta Conservation Technoogies Kashima Port & Industria Zone is ocated approximatey 80 kiometers northeast of Tokyo and one of the most popuar industria zone with stee, petrochemica, fertiizer and therma power pants in Japan. This zone is one of the 22 area deveoped under principe of the integrated deveopment and has been proceeding to dredge the vast sand coast and construct the port and Industria zone recaimed using the dredged sand. This Integrated industry system with port deveopment contributed to the tremendous economic growth as the driving force in postwar history of Japan. For port construction facing the Pacific Ocean, Japanese atest technoogies of that time for dredging, breakwater and so on has been used. Currenty the port is sti expanding. Since sea-water disposa yard is easiy infuenced by waves, construction work is progressed after waste is surey shut off with sea and probems of safety & environmenta preservation are ceared. work is carried out with poution-prevented curtain fencing around dredging area not to worsen surrounding environment with pouted water. And since most of sea-water disposa yards in our country are founded on weak ground, soi improvement is aso important theme. There are Sand compaction pie method and Deep mixed disposa method for soi improvement which are carried out to ensure safety of revetment and shutting water off.
