Original Engineering Consultants Co., Ltd

Original Engineering Consultants Co., Ltd., has been established in January 1962. As a consulting firm specialized in the fields of water supply, sewerage works, sanitation and solid waste treatment, the firm has accumulated vast experience of services such as investigation, planning, detailed design, construction supervision, etc. in those fields. The firm also has been making every efforts to computerize the engineering works since early days of establishment of the firm and it contributed remarkably for water supervisory control, flood prevention, mapping, accurate and rapid calculation on engineering works. The professional activities of the firm are duly registered with Japanese Government. It is significant that the company has no association what so ever with any contractors or manufacturers. All company shares are held by the members of board of directors. The firm is, therefore, totally independent and free of any control form other enterprises. The firms launched into overseas in 1977 mainly in Korea. Twenty regional offices located at key points in Japan and three overseas office in Korea,Philippines,and Kiribati are effectively operated. Overall activities are coordinated by the head office in Tokyo.  TECHNOLOGY OEC has released advanced design-assistance and data-processing technologies, which were developed from basic technologies for assessing, designing, and managing water supply system, sewerage systems and waste disposal. For example, take OEC's 3-D Structural Design System, URUSHI. In addition to its ability to rapidly generate elevations, cross-sections, and plan views of structures based on three-dimensional diagrams, this system is capable of automated production of parts and civil-engineering data while allowing design information to be shared over a network, making it compatible with the next generation of computer systems. Or consider MONJU, a technical information resource management system. This system offers centralized management of huge volumes of data in the form of maps and text, for example, data concerning sewer systems, part of a city's infrastructure. This information can be readily searched and easily updated. Further, OEC has found practical applications for facilities-management support systems that efficiently automate facilities management and management of capital assets. These systems have already been adopted by a large number of local governments, where they are highly regarded.Great expectations are paid for the future of "real flood maps," which is designed to forecast and help cope with floods through the analysis of the whole dynamics of rainwater on a regional basis. With this leading-edge technology, the uncertainty of a natural threat will be replaced by the certainty of concrete numbers. EXPERTISE As a professional organization of technical specialists in water and greenery, OEC aims to develop technologies as valuable resources from the viewpoint of achieving zero emission. OEC's concept of water as a resource is born of its advanced technologies for the efficient maintenance and management of water-supply and sewerage systems, and for the high-grade treatment of wastewater and rainwater. It is its expertise in water, acquired over many years of experience improving the quality of polluted water and developing systems for the control of flooding caused by rainwater, is the source of OEC's drive. OEC, not satisfied simply to develop new technologies and applications, continues to produce results at the forefront of the industry and of the age. For example, it has recently contributed to many of the facilities related to projects that fuse new approaches to lifestyles and the environment with cutting-edge technology, such as the Yamazaki Sewage Treatment Plant and the Okutone Amenity Park.
