  • Recently, the application of building information model (BIM) is evaluated as one of important issues in construction market through the analyzed results in successful case studies. This study suggests an integrated information management model based on BIM through the problem analysis in existing information model for design phase. The application of suggested model is verified by a case study of bridge project. Those automatic and integrated information models for design phase can be used for an effective information management model through project life cycle.

  • While occasional disasters have occurred recently in urban facilities such as bridges, buildings, subways, roads and others, the systematic safety management of urban facilities is greatly needed to prevent the disaster or to minimize the damages. This study proposes the way of setting-up and managing an building disaster information system so that this experience can be applied to other urban facilities to minimize trials and errors. With such a purpose, this study presents a building safety management information system and utilizes it for the building disasten information system. This study includes research agendas as follows : building maintenance and management infonnation system, setting-up and utilization the building safety management infonnation system, building disaster infonnation system using GIS. The results suggest that the building safety management infonnation system which can be related to the urban disaster infonnation system should be constructed in advance in order to utilize the building disaster infonnation system, and that, under this condition, it proved to be easily connected to the related database, especially GIS. And, to utilize such an infonnation system, the application programs such as safety evaluation program, cost estimation program and documents management program should be readily available. In addition, other functional programs related with maintenance and management should be designed and established. The schemes or devices for practical usage should be supplemented through a standardization and a pilot project in central government or Seoul Metropolitan Government level in order to set up and utilize the building safety management infonnation system, and the related laws or regulations should be prepared or amended to support the system.

  • Measuring the tensile strength of steel cables used to support bridges is a critical inspection item in terms of the safety of a bridge. Today, cable tension is measured with the vibration method and loadcell. Recently, some advanced countries have conducted studies on measuring tension with magnetic method and are suggesting prospective results. Since there were no such studies ongoing in Korea, we began a study on measuring tension with magnetic method as we are undergoing researches to improve the precision of measurements. It is necessary to consider the influence for the magnetic field and the temperature of steel cables in tension measurement of magnetic method. In this paper, we tested an output characteristic of tension sensor according to temperature and deduced temperature compensation coefficient in the given magnetic field and applied the compensation coefficient to the tension measurement system in the lab. We analyzed and evaluated testing results for the output voltages of the tension sensor according to cable tensions.

  • In Korea, the number of national facilities for which a safety inspection is mandatory is increasing, and a safer safety inspection method is needed. This study aimed to increase the efficiency of the bridge safety inspection by enabling rapid exterior inspection while securing the safety of inspectors by using drones to perform the safety inspections of bridges, which had mainly relied on visual inspections. For the research, the Youngjong Grand Bridge in Incheon was selected as a test bed and was divided into four parts: the warren truss, suspension bridge main cable, main tower, and pier. It was possible to establish a five-step standard procedure for drone safety inspections. The step-by-step contents of the standard procedure obtained as a result of this research are: Step 1, facility information collection and analysis, Step 2, analysis of vulnerable parts and drone flight planning, Step 3, drone photography and data processing, Step 4, condition evaluation by external inspection, Step 5, building of external inspection diagram and database. Therefore, if the safety inspections of civil engineering facilities including bridges are performed according to this standard procedure, it is expected that these inspection can be carried out more systematically and efficiently.

  • Integrated Urban Spatial Information Management Platform (USIMP) is defined as an operational environment where technologies for intelligent management of urban facilities are made possible through the integration of diverse technologies such as sensors for ground and underground facilities, middleware technology, wired and wireless network, GIS-USN linkage. To make the integration of these diverse technology possible, it is imperative to have a sound reference model for the platform. This paper provides a standardized reference model for USIMP based on the RM-OPD(Reference Model for Open Distributed Processing) standard.

  • Most construction information is being recorded in the form of electronic document. However, design documents generated in current practice are not suitable in share and exchange of information for disaster management. This study proposes how to develop th e XML Schema based semantic model of structural calculation document (SCD) for systematic storage and management of SCD information. in addition, 5 basic data types are developed for various expression forms appeared in the structural calculation documents. A prototype semantic model for steel bridge superstructure is developed based on the proposed method, and it is observed that the proposed method can be effectively used to build a standardized semantic model of SCD.

  • In the case of the construction industry, the relationship between process and cost should be appropriately distributed so that the finished product can be delivered at the minimum fee within the construction period. At that time, it should be considered the size of the bridge, the construction method, the environment and production capacity of the factory, and the transport distance. However, due to various reasons that occur during the construction period, problems such as construction delay, construction cost increase, and quality and reliability degradation occur. Therefore, a systematic and scientific construction technique and process management technology are needed to break away from the conventional method. The prefab(Pre-Fabrication) is a representative OSC (Off-Site Construction) method manufactured in a factory and constructed onsite. This study develops a resource and process plan optimization system for the process management of the Nodular girder, a prefab bridge girder. A simulation algorithm develops to automatically test various variables in the personnel equipment mobilization plan to derive the optimal value. And, the algorithm was applied to the Paju-Pocheon Expressway Construction (Section 3) Dohwa 4 Bridge under construction, and the results compare. Based on construction work standard product calculation, actual input manpower, equipment type, and quantity were applied to the Activity Card, and the amount of work by quantity counting, resource planning, and resource requirements was reflected. In the future, we plan to improve the accuracy of the program by applying forecasting techniques including various field data.
