The analysis method of stabilizing process and its program regarding large spatial structural systems are described in this paper. In this paper, the analysis of stabilizing process of the example structures, namely Olympic Fencing Arena, is performed and the jacking force of stabilizing process is proposed, and the characteristics of structural behavior is investigated. This result of research is applied to the design and construction of the actual structures and the reliability of the analysis is verified through comparison of the analysis results and the measured results in the field. When the analytical results is compared with the actual structural behavior, there is a little difference, but it is thought that the analysis results are quite reliable because it is very similar to the measured values in spite of construction and measurement errors.

It follows recently in an order augmentation of overseas construction market plant field and the project of oil gas field is increasing. Consequently, the hazard which secures the competitive power of the overseas plant enterprise of the domestic building industry enterprises the technical competitiveness security which stands, productivity improvement and strategy management propulsion back positive disposal plan establishment are demanded. Even from in that oil gas field of overseas plant enterprise for an industrial competitive power improvement the application of EPC circulation information which relates with a project accomplishment is more demanded, the EPC phased star efficiently it manages the circulation information contents which occurs from the business which is various it is not presented it cannot there is a contents classification system for. If with him about lower the draft the problem point of information omission back of occurrence and business subject for of the fringe land and duplication business occurs, about lower the productivity decrease actual condition is appearing with such problem point. The research which it sees consequently in order to improve the use characteristic of the augmentation of practical application of the contents management system of oil gas field and building industry information civil official establishhes the contents management system the BPM for (Business Process Management) to present the contents classification system of base, it does to sleep. The part of Business Process materiality the knowledge which is demanded, contents information and system anger it analyzes system anger of industrial equipment circulation information it takes a triangular position and to sleep it does.

A mound was constructed to install a caisson and sofa blocks underwater. The mound riprap, which were of uniform grade, size, shape, and specific gravity, formed the foundation for the support superstructure. Also, rubble leveling works were performed before installing structures such as caissons. In this study, underwater construction equipment was developed with a remotely controlled operating system and underwater environment monitoring system for unmanned underwater rubble leveling work. The performance of the developed equipment was verified using on-land and underwater tests. In addition to the performance verification, the construction process and economic efficiency of the equipment should be checked before applying it to the real construction field for commercial purposes. In this paper, a construction process using the developed equipment was proposed and compared with the existing rubble leveling method. The results demonstrated that the new construction method has higher economic efficiency and safety than the existing construction method.

With the social demands for tall building, the level of techniques for construction become high and there are various building materials. Also, the construction system become very complicated with the increase of worker. In spite of above facts, the method of construction management depends on the experimental capacity of a construction manager, and there are many unreasonable elements. These elements prevent well-going in construction process. To solve this problem, it is necessary to make a new system of construction management which is adequate for the condition of company and the contents of construction. In this study, the characteristic of production system and the present condition of construction management were investigated with the help of survey. Thus, the new method of construction management which can clear the previous problems was proposed.

The trend in construction industry, now, lies in improving efficiency and competitive power in construction management and on-the-spot instruction by combining with new IT technology. Above all, it is safe to say that the application of RFID technology can play a pivotal role at this point, but it is not that easy to apply RFID due to the physical, chemical and environmental peculiarities of construction materials. Thus, a study on the standardization of the usable frequency, specifications, protocol, and package administration is required. This study, as part of the study on the standardization, figured out the restrictions by attaching the existing RFID Tag to the construction materials, turned out the prototype of RFID Tag to perform a field test. In result the effective recognition range varies according to the physical and environmental peculiarities of construction materials; and the management efficiency varies as the attaching method and/or applying method. To analyze the management method (media, process etc.) systematically for the existing construction materials; to prepare more various restrictions and its solutions for practical construction spots will be the key for successful RFID implementation.

When various construction types of architectural construction are proceeded in order, the reinforced concrete construction is the frame construction which takes up the most important proportion among the construction process. Thus, the analysis of the effectiveness and productivity of the reinforced concrete construction is necessarily needed for smooth performance of construction projects. However, the conventional studies are performing the analysis of the productivity of only part(mould and steel) of the reinforced concrete construction and they have limitation in that they do not propose quantitatively the overall productivity of reinforced concrete construction.

Traditionally, the construction industry field is one of the typical fields using facet analysis method. Internationally the facet analysis method is applied to the classification scheme "Uniclass" or thesaurus "Construction Industry Thesaurus(CIT)". In the case of Korea, the facet analysis method is being used in classification scheme "Construction Industry Classification System" but it is difficult to find studies on facet analysis method in thesaurus or building case study. This study aims to establish facet types by introducing building of thesaurus for information retrieval in construction field using facet analysis method and to suggest building plan of thesaurus in construction field using facet analysis method. In this paper, We establish the 11 top facets(agent/patient, artifacts, abstract, material, parts/component, works, attribute, media, process, space, time) and the 13 subfacet as rudimental facets and suggest building plan according to thesaurus building procedure which is suggested by International Standard(ISO 25964-1). The result of this study is expected to apply to facet based thesaurus. And it is also expected to reuse in Taxonomy or Ontology etc. and to use in interoperability with the classification scheme of Construction filed.

With the development of digital technology, construction companies at home and abroad are in the process of computerizing work and site information for the purpose of improving work efficiency. To this end, various technologies such as BIM, digital twin, and AI-based safety management have been developed, but the accuracy and completeness of the related technologies are insufficient to be applied to the field. In this paper, the learning data that has undergone a pre-processing process optimized for recognition of construction information based on structural members is trained on an existing artificial intelligence model to improve recognition accuracy and evaluate its effectiveness. The artificial intelligence model optimized for the structural member created through this study will be used as a base technology for the technology that needs to confirm the safety of the structure in the future.
