Quality control of in-service inspection in nuclear island
During the refueling outages of PWRs, ISI in nuclear island will contribute to find the equipment degradation generated during its normal operation, which can lay a foundation for the safe operation of nuclear power plant. ISI of nuclear island equipment was carried out from two sides: implementation and management. A detailed process of nondestructive testing and quality control during the preparation stage, project implementation stage and postsession integration stage was presented in accordance with the project procedures. Main responsibilities of quality control personnel stand out in the whole process.
Study and Application of Information Management System for Government-Invested Construction Projects
Government-invested construction projects have their own characteristics, and effective management can be achieved only by adopting corresponding appropriate management approaches. The characteristics of government-invested construction project management and corresponding serious problems existed in present management are analyzed and summarized at first. Secondly, the countermeasures to above problems are put forward. Then, an information management system framework for government-invested project management is proposed on the basis of the foregoing work. This framework can realize the fusion of project information management system and E-government system and achieve the institutionalization, standardization, informatization and lifecycle management for government-invested project by means of multiple modernized information technologies and professional software. Finally, the development and application of the developed information system validate the effectiveness to promote the management level of government-invested construction project. The work involved in this paper can provide reference for the management of other similar construction projects.
Information Technology Planning Framework for Japanese General Contractors
Developments in information technology ~IT! continue to have a significant impact on the architectural/engineering/ construction ~A/E/C! industry. However, the issue of whether A/E/C organizations are receiving adequate returns from their IT invest- ments remains an important managerial concern. Recently, Pena-Mora, Vadhavkar, Perkins, and Weber introduced a strategic IT planning framework for construction projects that includes four steps: environmental scan, internal scrutiny, IT diffusion analysis, and IT invest- ment modeling. It analyzes the external and internal IT conditions of a project/firm, identifies the diffusion phase of IT in the project/firm, and finally evaluates the effects of IT investments on the project/firm. Although this framework was originally intended to plan future IT investments, we assume that the framework can also be used to evaluate ongoing or past IT investments in projects/firms. Following this idea, this paper presents an application of the Pena-Mora et al. framework to an ongoing IT project in Kajima Corporation, one of the largest Japanese general contractors. Kajima is currently developing an IT system called LINCS ~Linkage of Information for a New Construction System!. This synthetic information network system has been designed to share building data among design and construction stages and streamline design/build activities. By using the framework proposed in this paper, we analyzed how LINCS is justified in terms of its strategic and operational value for Kajima and its construction projects.
