The Korean government established a domestic specification system, and regulated that owner should produced construction project specifications, instead of special provisions, in design phase, January 1998. But in Korea the ability of construction engineers for construction project specification are insufficient. So the government had built up a database of standard specifications and developed a supporting system for writing construction project specification(SPECMAKE) in 1999. However, it is a PC base stand-alone system, so it is not convenient to update the database. In order to overcome these limitations, the purpose of this paper builds up a database of construction criteria and develops a automatic writing system for construction project specification on web base. The database contains standard specifications, design and construction guidelines related with construction business. And this paper describes the frameworks, the components, and the functions of the specifications writing system for the construction projects.

Due to the rapid development of Internet technology, qualities of Web services are steadily improving and the Web database systems are actively employed to efficiently manage proper informations in various fields. In this paper, we propose a Web database system for the efficient material management for reusing construction materials. The proposed Web-based management system is operated using the spring framework, after constructing a database based on the collected data including tag ID, Location, Material, State, and Cycle, using the RFID(: Radion Frequency IDentification) system equipped with a location estimation module. Recently, the processing problem for a large amount of the residues generated at the demolition stage of various buildings is magnified in the construction site. The proposed Web-based construction material management system is expected for improving the processing problem as increasing the reusability and for reducing the construction cost as efficiently managing the construction materials for the reuse.

Actual construction data of completed projects can be utilized for the economic, time benefit of improving the efficiency on planning, designing, estimating and managing tasks in succeeding projects. But the lack of the system which accumulates and manages the actual data with standardized type, it has not performed well and stayed on early stage. It is required not only specific plan for the utilization of actual data but a construction information management system which collects and processes far-reaching data with standardized from based on facility. Therefore, the purpose of this study is to develop a construction information management system for Apartment housing ,which stored data along project feature database, actual cost database and actual database based on the Web. This effort can make an offer the clearness of dull construction market and the base of construction intelligence

In this study, we intend to integrate the database(DB) method into one logical structure that is related to damage such as cause and type of damages occurring in the DMZ area. We divided the DMZ members into two types, which are classified into qualitative and quantitative aspects based on the current status survey for three years as a study of database construction, So that the actual data can be utilized in future restoration. The database construction through each restoration direction regarding the type of DMZ corruption is as follows. First, we recognized the necessity of restoration of the damaged area of the DMZ, and approached it as a plan to select the damaged mark. Second, DMZ database reconstruction can be used as a restoration of damages, suggesting more information and restoration type through building an ecological database for education and research. Third, in order to maintain and restore restoration of damaged areas continuously at the national level, it is necessary to institutionalize guidelines for reasonable internal restoration in the national level as data that can be credited externally and can be acknowledged as the latest data.

Turn-key and CMF(CM for Fee) have been selected as procurement paths of large public projects in Korea. However, recently, researches and discussions on CMR(CM at Risk) have been popular as the Korean government seeks for alternative procurement paths to enhance the performance. In the CMR projects, the part who is responsible for construction management should predict and control the potential risks for guaranteeing benefits. In this research, CMR projects in which a general contractor plays the role as CMr is mainly analyzed. We give attentions to risk management during construction process given that subcontractors, main parts in this phase, work in various ways and thus more chances for faults exist. In this case, CMr manages risks to control the procedure of project. So, potential risk factors can constitute the database, and that database can be matched to following activity. And construction manager can forecast measures of risk using the result of matching. This chain of activities increase efficiency in roles of CMr on CMR(CM at Risk). Furthermore this study will propose one of the solution of Construction Management Module.

Recently, the number of vehicles equipped with cameras that are generally used to recognize surroundings is increasing. For robust recognition, a huge amount of tests under various environments are performed. Furthermore, the installation position or orientation of the camera is also changed depending on the vehicle. This change also accompanies many tests. Correspondingly, a large cost and a great deal of manpower are required to perform these tests. This paper proposes a method to cut these costs while conducting enough tests through the construction of a database of videos and a geometric transformation of images.

Construction industry has the form of industry progressed through mutual cooperation among participants in various fields. Accordingly, it may be referred to as an aggregate of information where various pieces of information are generated and managed according to each construction phase. Most of the information on the construction project is issued in the form of a document. And document management of the site is critical to successful execution of the project. Therefore, in the construction site to use IT technology for efficient information management. But, most of the information on the construction site is managed by the non-structured document. and Information management in the construction site is difficult to lack of information management systems. In this study, proposed construction information database structure and breakdown structure to the information management of the construction site through the BIM technology. Therefore, previous studies were reviewed about the document management and information link management. and Space breakdown structure and information breakdown structure was proposed to structure the information of the construction site and Database for information storage is designed. And, BIM-based construction information database was examined through the application scenario.

The efficient materials management in construction field is a very important work required for designing and demolishing building. As the waste amount caused by the building demolition is increased, the concern related to the treatment method, recyclability, and effect on the environment have been gradually increased. In general, the conventional databases for the construction materials management does not consider the reuse of the construction materials on steps for the building demolition and reconstruction, but they only consider managing the type and input amount of them. In this paper, we propose the database system for efficiently managing the various construction materials informations including the location and condition of each construction materials for the efficient reuse of them on the building demolition and reconstruction. The considered informations are obtained the RFID(: Radio Frequency IDentification) system with on-board the location estimation module. Using the reuse management of construction materials, based on the proposed database, we expect the reduction of the construction cost and time.
