As building construction projects have been more higher and bigger in scale, the needs for cost reduction, productivity improvement, and reducing of work terms have rapidly increased in recent years. There has been, accordingly, a great emphasis on the necessity of logistics and progress management by well-organized system developed based on the appliance of different management theories. Although highly developed IT technology has contributed to the efficiency and effectiveness in information research and project management, RFID has been merely applied to a single progress or a few types of materials in current management studies, not to the overall process of the projects. This research proposes a consistent and systemized approach for decision making in adopting RFID technology in a construction project to support construction logistics and progress management. With a decision making model that consists of process model and template developed in this research, risks in cost, time, and error in building RFID-based construction logistics and progress management could be minimized.

There are many problems in management of high-rise building construction performed in downtown area due to limited spaces and equipments for increasing kinds and quantities of material. By these restrictions, problems such as increase of construction cost. delay of construction period, decrease of productivity, occurrence of accident are caused. Recently, studies on JIT concept have focused on construction materials as a solution for the problems. But, studies about finishing material are insufficient yet. Accordingly, this study suggests flowing of current material management, JIT management effect, and development direction of lifting-up and procurement system with Low-emissivity double Glazing, among of main finishing materials.

As construction projects increase their complexity, variety, and scale, various recognition applications (such as RFID, bar-code etc.) have been tried for managing material effectively in construction projects. However, existing recognition applications for construction material management have some limitations that cause additional works (such as attaching RFID tag), additional cost (labor cost, recognition device cost, etc.), and cognitive impairment of workers. Therefore, this study proposed a character recognition technology as an alternative of previous recognition technologies such as RFID, bar-code, etc. The technical feasibility of proposed technology was validated by three recognition tests. Additionally, this study proposed code the structure to manage materials using the character recognition technology. The effects of character recognition technology are presented by comparing with existing RFID-based logistics processes.

The access monitoring and control system of vehicles involved in construction logistics has been evolved from paper-based through bar code-based and to RFID-based management with pursuing automatic data collection and management. However, existing management methods have a limit that they still need manpower allocation for access control of vehicles. Therefore this research has proposed an framework that includes devices and an information system for effective and efficient data collection for access control of vehicles for construction logistics. And the proposed framework has been verified through a laboratory test using a prototype system developed in this research. It is expected that the installation methods of RFID antenna and tag for the framework could be applied to not only the access control of construction site but also various RFID applications at construction sites.

최근 건설교통부, 해양수산부, 산업자원부 등 정부산하기관으로 물류업계의 권익을 대변하는 많은 협회 · 단체가 활동하고 있다. 23년의 역사와 전통을 가지고 있는 (사)한국물류협회를 비롯하여, 국제물류지원단, 한국유통물류진흥원, 한국물류관리사협회 등이라 할수 있다. 우리나라 물류산업이 급성장할 수 있었던 밑바탕에는 이들 협회 · 단체들의 노력이 있었다는 것에 누구도 이견을 가지는 사람은 없을 것이다. 이와같이 비영리 사단법인으로 공식적으로 활동해온 협회도 있지만, 단순히 연구회 모임으로 활동하는 학회나 소모임 동아리도 많다. 여러 모임 중에서도 국제물류연구회는 '한반도의 동북아시아 물류중심지화' 라는 비전의 실현을 향한 의지와 애정을 가진 산 · 학 · 연 관계자들의 토론 연구회 모임이다. 지난 2001년 9월 창립하여 매월 1회씩 정기적인 학술 세미나를 개최하면서 물류산업발전에 많은 기여를 해오고 있다. 창립 5주년을 맞이한 국제물류연구회는 현재 건설교통부 산하 사단법인으로 등록을 마치고 그 결과인 인가를 기다리고 있다. 앞으로 기존의 물류관련 학회와는 다른 연구회로 거듭나기를 기대해 보며, 국제물류연구회는 어떤 단체인지, 국내 물류연구회의 제2대 회장으로 있는 이호영 함부르크 항만청을 한국대표를 만나 보았다.

The term 'green' has become an important way of survival for the construction industry in 21th century in accordance with the emergence of the environmental crisis due to the climatic change. Especially the policy of carbon taxation, planed to be introduced from 2012, is expected to be a considerable burden to the construction industry which has abundant carbon emission during the resource transportation due to the complexity of resources and local distribution of the construction sites. In this regard, this study shows an optimizing strategy for delivery frequency, which downsizes the net distribution costs based on the assumption that, despite of its other advantagements, the frequent small lot mode of JIT delivery would take negative effects due to the increase of costs of transportation and carbon emission once the carbon taxation policy carried out. To simulate the efficiency of the management strategies, the System Dynamics modeling has been used. The results show that the frequent small lot transportation strategy is now always efficient method to these changes, and that the frequency of transportation should be re-determinated according to the extent of the imposition of carbon tax. This study provides the conceptual frame for an efficient management of transportation system of the construction industry, showing necessity of change of the resource transportation systems through analysing JIT deliver system in accordance with the global changes in environmental economy.

There have been research and developments for effective and efficient logistics and progress management in a construction project. Among them, RFID+4D has been developed for the supply chain management of long-lead item materials such as steel component, precast concrete component and curtain wall by integrating RFID with 4D CAD. And the feasibility of RFID+4D has been verified and validated and the benefits in terms of time and cost were shown in several case studies. However, the previous development of RFID+4D has not been adapted widely because of additional modeling cost, non-real time data update, additional labor for data update, and so forth. Therefore, this research has proposed a framework and process for solving these problems. And the web based simulation system has been developed and verified based on the proposed framework. The proposed framework and process can improve the existing RFID+4D system in a construction project by saving its operation cost and utilizing project information more efficiently and effectively. Also it is expected that the proposed framework could be applied to a method transferring design RIM data to construction BIM data.

In construction industry, the cost related to material is different from each other under the characteristic of projects. However, it has 40% of the whole cost in the composition of prime cost. Recently, While the construction work become bigger, specialized and complex, it is complex to carry in materials because of shortage of space. However, in many cases, material management has been underestimated as well as the material management is depending on experience of site managers so it has been studied about frequently. In this study, I suggest four classification methods of material characteristic ETO, ATO, MTO, MTS. I also analyze what the most efficient supply management of the site materials is through researching the characteristics of the material distribution. In conclusion, I would like to build the material management classification for the characteristics of materials.
