Japan Conservation Engineers wins 2005 BE Award

Japan Conservation Engineers Company Ltd. has won a 2005 BE Award for its Examples of Construction of Landslide GIS project in the Akita, Yamagata, and Kanagawa prefectures in Japan. The award category was “Geospatial: Geospatial Modeling.” The BE Awards of Excellence are selected by an independent jury of industry experts and are presented at an evening ceremony during the annual BE Conference (www.be.org), honoring the work of Bentley users improving the world’s infrastructure. These projects set benchmarks for their industries, and showcase the imagination and technical mastery of the organizations that created them.

The Japan Conservation Engineers’ Landslide GIS system lets engineers better evaluate, present to clients and the public, and manage projects designed to prevent landslides. The system does this by enabling engineers to perform 3D analysis of the hydrogeological structures and landslide prevention projects in landslide areas, create a 3D simulation of landslide movements and store and manage 3D surface and sub-surface data. The Landslide GIS’s 3D analysis capability lets engineers easily produce an image of the landslide area’s geological structure. This image can then be used to perform a variety of analyses, such as slope stability evaluations, to provide a hazard risk assessment.

The 3D analysis can also model a landslide’s sliding mass to quickly design effective prevention measures. Three-dimensional drawings generated from the model can help the public better understand the landslide dangers in their community, as well as to appreciate the benefits of any landslide prevention projects being proposed.

An even more dramatic depiction of these dangers can be produced by using the new system to create a lifelike model that shows actual land mass movement during a landslide. Soil type maps are combined with highly accurate digital elevation models to show the before and after conditions of an area affected by the landslide. Survey data collected over the study period provides the basis for the animation. Orthophotos are then laid over the study area to create a realistic landslide movement simulation. These animations reveal the extent of devastation that a landslide is likely to cause, including its impact on protected areas and the people living in and around them. Such information can speed approvals for prevention projects by making it easier for the public to visualize the dangers they face from this destructive force. Japan Conservation Engineers, which was established in 1966, specializes in surveying, planning, designing, construction, and construction management specific to mountain hazard management and mitigation projects.
