  • Determining on a particular construction method is typically decided in the initial phases of a project. However, changing conditions during actual construction may require a different method or technology to be employed. Providing an option for project managers to change construction provides flexibility that can increase value to the overall project. This research provides the ability to modify construction methods as a real option, which allows its value to be modeled. The research also formalizes a way to integrate a binomial lattice model with the Earned Value Method's S-curve. The integrated model provides a decision support tool that planners can use to determine whether to exercise the option depending on the status metrics provided by EVM.

  • The small-and-medium sized construction sites are in weak state of safety management because of the variable working environments, the lack of safety techniques and the weak economic conditions, and industrial accidents of these sites were occupied 60% of the total construction accidents. Recently, the safety engineer's number are not to be enough at the small-and-medium sized construction sites. Therefore, the safety engineer's works are addition to more and more. This paper is a development of the integrated program which using composition of construction safety management expenses. It is an management tool which helps to saving time of construction safety engineer. A method of development composition, to used Brain Storming for a place of meeting to construction safety management counselors.

  • Currently, the Korean Smart Construction Corporation aims to stimulate overseas expansion of smart construction technology centered on Expressway development. In addition, the integrated classification system of construction information with Work Breakdown Structure(WBS) is currently being established in Korea, but its application to the construction industry is limited. In this study, data generation using simulation is carried out at the lowest level of WBS presented by the Korea Expressway Corporation, and detailed process productivity is predicted by site conditions.

  • Several studies have been performed globally on the construction of integrated systems that are available for the integrated use of 3D geographic information on terrain and oceans. Research on 3D geographic modeling is also facilitated by the application of Lidar surveying, which enables the highly accurate realization of 3D geographic information for a wide area of land. In addition, a few marine research organizations have been conducting investigations and surveying diverse ocean information for building and applying MGIS(Marine Geographic Information System). However, the construction of integrated geographic information systems for both terrain and oceans has certain limitations resulting from the inconsistency in reference systems and datum levels between two data. Therefore, in this investigation, integrated geospatial information has been realized by using a combined topographical map, after matching the reference systems and datum levels by integration of airborne Lidar data and multi-beam echo sounder data. To verify the accuracy of the integrated geospatial information data, ten randomly selected samples from study areas were selected and analyzed. The results show that the 10 analyzed data samples have an RMSE of 0.46m, which meets the IHO standard(0.5m) for depth accuracy of hydrographic surveys.

  • As interest in green building has increased, construction market has evolved through BIM-based architecture also, BIM-based technologies have been developed simultaneously. Due to this aspect, the need of environmental analysis software utilizing BIM data became essential. This study shows that BIM-based integrated module provides objective analysis to proceed quick decision-making for a proposal. In addition to that, this integrated module creates a model through BIM data to analyze and report residential environment and energy consumption such as, daylight, view, ventilation and privacy in order to practically apply the BIM technology from the schematic design.

  • In this paper, an integrated management software is developed to promote the business competitive power. The interoperability among the software accounts for an ever growing performance of petrochemical plant project. If the interoperability is built up, company has taken advantages of quality, schedule, cost, and safety by active communication. The advantage of an integrated management software is examined in three aspects. In efficiency aspect, It takes advantage of the saving about the various information and the standard of project performance procedure. In quality, the integration gave aid to a quality improvement through team collaboration and data management within project life cycle. In cost, poor communications between systems waste 30% of project costs. If information could be inputted once and used by all, reductions in delivery time up to 40% were possible. Therefore, 10% savings of engineering cost was also possible.

  • In order to conduct the effective integration of computer-aided conceptual design for integrated nuclear power reactor, not only is a smooth information flow required, but also decision making fur both conceptual design and construction process design must be synthesized. In addition to the aboves, the relations between the one step and another step and the methodologies to optimize the decision variables are verified, in this paper especially, that is, scaling laws and scaling criteria. In the respect with the running of the system, the integrated optimization process is proposed in which decisions concerning both conceptual design are simultaneously made. According to the proposed reactor types and power levels, an integrated optimization problems are formulated. This optimization is expressed as a multi-objective optimization problem. The algorithm for solving the problem is also presented. The proposed method is applied to designing a integrated sub-critical reactors.

  • As the number of the company to acquire the certifications of ISO 9001/1400, OHSAS 18001(not official standard) is increasing, it is needed to construct a integrated business management system for the efficient application of the certifications. In this circumstances the integrated construction of the SHE & Q system so called, for Safety, Health, Environment and Qualify can take a part for the communication in the customer, the company convenience and the interested parties(the worker. the supplier and the provider). In case that each certification systems are integrated, the problems of the redundancy in the management processes and the conflicting demands are able to be solved and the efficiency of the restricted management resources fan be raised as the complexity of the redundancies in the certification management is simplified. This paper deals with the integrated strategies, its convenience and its expecting merit and demerit for the efficient application of the certification parties haying the various characters.
