The Korean society faces a new issue of accepting foreign workers. Foreign labors in construction industry reached about 400,000 recently. Thus they have become one of the essential resources to fill up insufficient labor supplies in construction industry. And it is important how to manage foreign labors efficiently. However there are few studies focused on this subject. Purpose of this study is to research productivity of foreign labors in the domestic construction site. So investigate the value of foreign labors. Also this study forecast elements effect on foreign labors productivity in the construction industry. And research what element is more important to improve productivity and what element is more difficult to manage. In the result, this study is expected to prospect effective method of foreign labor's management in the domestic construction industry, so contribute to utilize foreign labors more efficiently.

The Korean society, which faces a new issue of foreign labores, is actively conducing safety consciousness of foreign labors. Foreign labors of domestic industry reached about 360,000 recently. it has become the essential resources to fill up insufficient labor in construction industry. Although most foreign labors participate in safety education well and understand its object, some foreign labors have negative recognition of it. Some foreign labors well comprehend the importance of safety facilities but think those unnecessary. Based on these results, this research pointed out the need to review training manuals, the development of educational programs, improvement of educational facilities to improve safety education of construction, and finally to discussed these issues.

The intention of this study is to analyze safety consciousness of construction labors in Gawang-Ju region. According to Korea Occupational Safety & Health Agency, the rate of disaster in construction industry is very high comparing with other fields. Most of all, the consciousness of construction labors is very important because accidents are caused from it mainly. For this reason, it is necessary to recognize safety consciousness of labors who directly work in construction field. For decreasing the rate of disaster in construction, I examined and analyzed safety consciousness of construction labors and then, groped improvement of safety activity. Finally, this study deducted improvement of safety activities and management.

최근 수년 동안에 국내에서는 많은 초고층건물들이 완공되었다. 지금도 다수의 초고층건물들이 시공되고 있으며, 심지어 100층 이상 규모의 초고층건물까지도 기획 중에 있다. 이러한 초고층건물공사의 현장관리 측면에서 중요성이 강조되는 관리항목들 중 하나는 시공 과정 중에 발생하는 자원의 수직이동을 관리하는 것이다. 특히 짓고자 하는 건물의 높이가 높아질수록 작업원들이 각자의 작업층으로 이동하는데 걸리는 시간은 길어지며, 자칫하면 이것이 현장의 작업능률과 생산성을 떨어뜨리는 원인이 될 수 있다. 이에 본 연구에서는 초고층건물공사 수행 시 작업원의 수직이동을 체계적으로 관리하기 위한 한 가지 방안으로서 이산형 시뮬레이션을 사용한 작업원의 수직이동계획 프로세스를 제안하였으며, 계획 프로젝트인 MT 130 타워공사를 대상으로 이것의 적정성을 검토하였다.

2014년 기준 29만명의 근로자가 전체 1조 3천억원의 임금체불을 당하는 것으로 나타났으며 특히 노동집약적 산업인 건설산업의 특성상 임금체불로 인한 부작용이 심각한 실정이다. 그럼에도 불구하고 임금체불 해소를 위한 연구는 근로자의 인식을 배제한체 임금체불 해소제도 개선에 주안점을 두고 이루어 지고 있다. 따라서 본 연구에서는 임금체불 해소를 위하여 근로자의 인식에 기반하여 임금체불 해소절차에 대한 실효성을 분석하고 근로자들의 인식을 파악하고자 한다. 연구 결과 전체 근로자 및 관리자의 30% 이상이 임금체불 해소절차 및 해소제도에 대하여 전혀 인식하지 못하고 있었으며 연구체불 해소를 위한 제도 또한 많은 개선이 필요한 것으로 나타났다.

Safety is a big issue in the construction sites. For safe and secure management, tracking locations of construction resources such as labors, materials, machineries, vehicles and so on is important. The materials, machineries and vehicles could be controlled by computer, whereas the movement of labors does not have fixed pattern. So, the location and movement of labors need to be monitored continuously for safety. In general, Global Positioning System(GPS) is an opt solution to obtain the location information in outside environments. But it cannot be used for indoor locations as it requires a clear Line-Of-Sight(LOS) to satellites Therefore, indoor location monitoring system could be a convenient alternative for environments such as tunnel and indoor building construction sites. This paper presents a case study to investigate feasibility of Wi-Fi based indoor location monitoring system in construction site. The system is developed by using fingerprint map of gathering Received Signal Strength Indication(RSSI) from each Access Point(AP). The signal information is gathered by Radio Frequency Identification (RFID) tags, which are attached on a helmet of labors to track their locations, and is sent to server computer. Experiments were conducted in a shield tunnel construction site at Guangzhou, China. This study consists of three phases as follows: First, we have a tracking test in entrance area of tunnel construction site. This experiment was performed to find the effective geometry of APs installation. The geometry of APs installation was changed for finding effective locations, and the experiment was performed using one and more tags. Second, APs were separated into two groups, and they were connected with LAN cable in tunnel construction site. The purpose of this experiment was to check the validity of group separating strategy. One group was installed around the entrance and the other one was installed inside the tunnel. Finally, we installed the system inner area of tunnel, boring machine area, and checked the performance with varying conditions (the presence of obstacles such as train, worker, and so on). Accuracy of this study was calculated from the data, which was collected at some known points. Experimental results showed that WiFi-based indoor location system has a level of accuracy of a few meters in tunnel construction site. From the results, it is inferred that the location tracking system can track the approximate location of labors in the construction site. It is able to alert the labors when they are closer to dangerous zones like poisonous region or cave-in..

A high-rise building construction in Korea has some problems in engineering, construction and management technologies although the high-rise building construction is recently booming. In addition, the lack of skilled construction labors is increasing, so the development for methods is needed to reduce the labors by prefabrication and mechanization. A re-bar work is one of very important works with regard to cost and schedule management in the high-rise building construction. Nevertheless, the re-bar work has some problems that it is needed many re-bars for joints linking and much time for lifting due to high-rise buildings, and it is difficult to level the skill of labors. So, in this study, the pre-fabrication of three-story height in column re-bars is proposed and the results of an implementation are analyzed and explored by a case study. As the results of case study, the pre-fabrication of three-story heights in column re-bars could reduce the cost in the re-bar work and accelerate the time in the structural frame work. In addition, the pre-fabrication of three-story height in column re-bars could solve the problems such as the waste of many re-bars for joints linking, and the lack of the skilled labors.

Increasing wages and decreasing skilled labors are problems awaiting solution. The development of automatic technologies contributes to accelerating the one of construction automation. Thus, this study is to suggest the way to develop the automated building construction system base on one performed in Japan in order to solve urgent problems of construction industry in Korea. Therefore interviews and questionnaires were performed based on experts who work for the automated building construction system field and analyzed through analytic hierarchy process. In doing so, it was the most important factor to develop a branch of automatic, mechanical or machine technologies for the automated building construction system. Especially the study indicated the importance of the technologies to substitute skilled labors such as a robot. This research could contribute to developing the automated building construction which is very unique and suitable for construction industry in Korea.
