Advances in new information technology enable practitioners at construction sites to capture image information on overall sites and various work results through digital cameras. Also more and more government agencies and clients are accepting construction site information in a digital format. This research developed an Internet-based construction image information management system for effective construction management and sharing information among project participants. This system named CiMS provides a way to store/search/share site image information by representing the information through the combination of work items, work areas, performing companies, captured dates and purposes. CiMS has been applied in a real construction project for system refinement and verification. It is expected that CiMS can improve the construction site photo management paradigm, and the contents of CiMS can be incorporated into the corporate knowledge database.

Information trend in whole domestic industries can not be a exception for construction industry either. However, Construction companies applying quality information management system(QIMS) through practical use of internet is very limited. Consequently, this research finds the established sample of quality information management system(QIMS) of H-construction company out, and the quality is established to the practical use of the system to be like the this. therefore, the construction industry wished to become opportunity that construction industry competitive power is recognized cosmopolitanly to quality management system(QMS).

Construction projects are managed by focusing on the results of projects. Moreover, cost and schedule are managed separately even though the efficiency of integrated management is very high. This paper proposes existing and progress control research of existing quantity the integrated information uses WBS-CBS. Schedule and cost are most important in construction projects. Specially, progress and cost are relationship of the managing integrated in many construction management. The quantity of materials for the works of construction is the base to create activities and a network. The quantity of materials of materials for the elemens of a building is a base of cost estimation and resource. allocation. This study suggest method for relating the schedule and cost information through the case study of construction field engineers.

Today's construction is a large-scale and long life span program, so called Mega-scale project, that every moment constructor faces much of hardships, It is because of a large amount of stakeholders, data and complicated relationship among workers. In order to overcome these problems, IETM(Interactive Electronic Technical Manual) has been introduced to construction industry recently, It is regarded as a useful tool for handling the data, procedures of the construction, but it is similar to existing IT-based information systems, the PMIS(Project Management Information System) and the KMS(Knowledge Management System), without characterizing. This research is intended to find out IETM's property and to present the Ontology scheme discriminating Construction IETM from existing systems..

Building Information Modeling (BIM) encourages effective information share and utilization among project participants during entire life cycle of facility. This paper presents a method that keeps track of the historical quality records involved in construction operations and facilitates using BIM. The method is coded into BIM based Quality Record Traceability (BIM-QRT) System that makes use of historical records obtained from database administrating construction operations. This study is of value to practitioners because the method makes clear the project participants' responsibility relative to the quality of each and every element of the facility. The main objective of this research is to develop an accurate, fully automated method for construction Quality Record Tracking by using a BIM along with construction operations data obtained by information technology. Test cases verify the usability and validity of the methods implemented in the system.

Documenting work-in-progress on construction sites using images captured with smartphones, point-and-shoot cameras, and Unmanned Aerial Vehicles (UAVs) has gained significant popularity among practitioners. The spatial and temporal density of these large-scale site image collections and the availability of 4D Building Information Models (BIM) provide a unique opportunity to develop BIM-driven visual analytics that can quickly and easily detect and visualize construction progress deviations. Building on these emerging sources of information this paper presents a pipeline for model-driven visual analytics of construction progress. It particularly focuses on the following key steps: 1) capturing, transferring, and storing images; 2) BIM-driven analytics to identify performance deviations, and 3) visualizations that enable root-cause assessments on performance deviations. The information requirements, and the challenges and opportunities for improvements in data collection, plan preparations, progress deviation analysis particularly under limited visibility, and transforming identified deviations into performance metrics to enable root-cause assessments are discussed using several real world case studies.

A lot of construction companies in overseas markets of construction try to change 2D CAD to 3D CAD for improving business ability and change to Building Information Modeling(BIM) for integrating information produced from construction life cycle. In America, GSA(General Service Administration) requires a design drawing planed by BIM and in Singapore and Europe, the government encourages architectures to use this tool. Recently in the domestic market, many organizations related construction industry are aware of importance of 3D CAD integrated information, and try to use BIM. Therefore, this research would analyze how does BIM affect construction industry and derive influence factors and provide basic data for using BIM.

In construction industry, workers' accident rates are relatively high compared to those of other industries. These high accidents rates are mostly due to the characteristics of construction process. In order to effectively reduce the accident rates, it is required to develop not only immediate measures but also long-term programs of instruction, training, and education. In addition, well-analyzed information on past history is required for the prevention of accidents. By examining about 800 cases of construction accidents that happened between Jan. 1992 and Dec. 2000, this paper developed an information system that provides appropriated safety information to the construction workers. This system is expected to contribute to the workers' safety in construction industry.

The information and communications construction business has the characteristics of an infrastructure industry and responsibility for the construction and maintenance of all ICT infrastructures. With the recent proliferation of the smart convergence of various industries based on ICT infrastructure, the role of the information and communications construction business has been highlighted to accommodate the convergence and implementation environment in construction and medical industries. Therefore, this paper seeks policy measures to establish the new role of the information and communications business under the rapidly developing smart convergence environment and the priorities of policy measures to strengthen the capability of the information and communications business using a quantitative model. The analysis result suggests that the difference in importance of each policy measure should be considered in order to execute effectively the policy of promoting the information and communications construction business. Given the constraint of limited budget, policy priorities include the development of new markets, and establishment of incentive for new technology. This study is significant for its theoretical contribution, being the first quantitative approach to policy priorities for the promotion of information and communications construction business under the smart convertgence environment.
