오늘날 국내 기업들의 관심은 업종을 가리지 않고 정보기술(IT)로 집중하여 고객관계관리(CRM), SCM, ERP등과 같은 다양한 기법들을 도입하지 않으면 경쟁에서 도태될 것 같은 분위기로 전환되고 있으며, 이러한 사항은 건설산업에서도 나타나고 있다. 그러나 국내 건설기업들의 홈페이지에는 단순히 자사의 홍보나 시스템 활용부문에 한정된 구성을 취하고 있으며, 고객들의 참여유도 역시 낮은 수준을 유지하고 있는 실정으로 조사되었다. 이에 본 연구는 타 산업의 구축사례와 건설관련자들의 설문조사를 분석하여 고객관계관리(CRM) 개념을 기반으로 한 건설기업들의 웹사이트 활성화를 위한 기초자료를 제시한다.

Due to harsh conditions of disaster areas, understanding of current feature of collapsed buildings, terrain, and other infrastructures is critical issue for disaster managers. However, because of difficulties in acquiring the geographical information of the disaster site such as large disaster site and limited capability of rescue workers, comprehensive site investigation of current location of survivors buried under the remains of the building is not an easy task for disaster managers. To overcome these circumstances of disaster site, this study makes use of an unmanned aerial vehicle, commonly known as a drone to effectively acquire current image data from the large disaster areas. The framework of 3D model reconstruction of disaster site using aerial imagery acquired by drones was also presented. The proposed methodology is expected to assist rescue workers and disaster managers in achieving a rapid and accurate identification of survivors under the collapsed building.

The noise emitted from an excavator has long been a cause of environmental disputes, while causing displeasure to the nearby residents. So, the ministry of environment adopted the construction machinery noise labeling system to encourage the construction machinery manufacturing companies to develop the low noise construction machinery voluntarily. But, as the quality of life improves, a growing number of people desire the comfortable and quite environment to live in. Under the situation, noise from the construction machinery has been a major cause for stress and complaints. When the noise dispute happened in the construction site, the sound pressure level of the construction machinery like a excavator was measured at the lot boundary of the noise victim's residence to judge how much noise damage occur. But the sound pressure level of the construction machinery is measured differently according to the acoustic environment of construction site and the measuring position, respectively, which makes it difficulty to judge whether the noise damage occur or not. As the sound power level of noise source is not affected by the acoustic environment of construction site and the measuring position, if we use the information of the sound power level, it will be easy to judge whether the noise damage occur and to establish the soundproofing measures. Therefore, we derive the sound power level regression model of the excavator to judge whether the noise emitted from the excavator damages to residents near the construction site. Also, the sound power level regression model of the excavator drawn in this paper will help construction companies to plan the noise reduction program in the construction sites.

There is a need for effective tracking and control of material loading and delivery time especially during the finishing-work phases to eliminate the need for lay-down space on the site. Hence, it is essential to monitor the relevant information regarding material procurement in construction sites, and it is also the key factor for successful site control and the adoption of the Just-in-Time concept for high-rise building construction. The purpose of this study is to test RFID's readability in order to develop a finishing material monitoring system through the application of RFID technology.

Small islands in humid and hot climates have received less attention development due to lack of resources and difficulties for in-situ construction. This paper addresses this problem by presenting a modular system for sustainable construction of a resort hotel in accordance with the international tourism standards, in addition to, minimizing undesirable effects on nature. This has been achieved by review of literature in the scope of off-site construction and identification of the natural geographical features of Herndurabi Island. According to the information acquired, a feasibility study and design practice have been conducted to achieve a reasonable solution to equip Hendurabi Island as a sample with a self-sufficient prefabricate resort hotel. Findings indicate that the volumetric prefabricated modules would be a solution to devising a framework for design and construction in remote regions.

건설 프로젝트가 점차 대형화, 복잡화, 전문화 되면서 지속적으로 변화하는 건설 환경에 대응할 수 있는 프로젝트 관리 기법 개발에 대한 요구가 증가하고 있다. 건설 프로젝트의 특성상 관리 기법은 건설 현장이나 구조물의 유지 관리 단계에서 발생하는 방대한 양의 정보를 실시간으로 수집하고 처리하여 표현할 수 있어야 한다. 이를 위해 국내외적으로 실시간 3차원 공간 모델링 방법의 개발에 대한 연구가 활발히 진행되고 있으며, 실시간 3D 공간 정보 획득은 모델링을 위한 필수 요소라 할 수 있다. 최근 개발된 플래시 레이다는 실시간으로 주변 환경에 대한 3차원 공간 정보 획득이 가능하도록 하는 장비로 건설 산업에서의 3차원 공간 모델링 시스템에 가장 적합한 기술이라 할 수 있다. 본 논문에서는 보다 정확한 3차원 공간 모델링을 위해 플래시 레이다의 장비 성능을 파악하고, 실험을 통해 이를 이용하여 획득한 3차원 공간 데이터의 정확성을 검증함으로써 건설현장에 대한 장비의 적용성을 검토하고자 한다.

Nowadays, the existing manual method for recording actual progress of the construction site has some drawbacks, such as great reliance on the experience of professional engineers, work-intensive, time consuming and error prone. A method integrating computer vision and BIM(Building Information Modeling) is presented for indoor automatic progress monitoring. The developed method can accurately calculate the engineering quantity of target component in the time-lapse images. Firstly, sample images of on-site target are collected for training the classifier. After the construction images are identified by edge detection and classifier, a voting algorithm based on mathematical geometry and vector operation will divide the target contour. Then, according to the camera calibration principle, the image pixel coordinates are conversed into the real world Coordinate and the real coordinates would be corrected with the help of the geometric information in BIM model. Finally, the actual engineering quantity is calculated.

Productivity has been a wide-ranging challenge for the construction industry, both in Australia and globally. Particularly in Western Australia's construction and resources sectors, continuously low productivity will potentially discourage future investments. The emergence of the global marketplace necessitates that the supply chain needs to focus on the concept of the holistic efficiency. The isolated geographical position of Australia only exacerbates this phenomenon. In recent years, Building Information Modelling (BIM) has been suggested as an efficient way to help productivity improve and information management throughout supply chains. This keynote talk will focus on discussing ways of implementing BIM to enhance site productivity focusing on Western Australia's construction projects. It will show new trends of its applications to accomplish an innovative way in construction project management. The talk will also give an insightful summary of integrated methods with state-of-the-art technologies backboned by the BIM cases from construction and oil and gas industry projects.
