최근 이슈가 되고 있는 미세먼지(fine dust)는 직경이 $10{\mu}g/m^3$이하인 미립자물질(particulate matter)로서, 흡입 시 인체에 치명적인 악영향을 주는 오염물질로 분류되어 있다. 미세먼지가 바람에 날려 비산할 때 주변에 끼치는 악영향이 증가하므로, 이러한 비산먼지(fugitive dust)를 잘 통제해야 한다. 특히 건설업은 한국에서 가장 비산먼지를 많이 배출하는 사업 분야이므로, 건설현장에서 배출되는 비산먼지를 잘 관리하는 것이 국내 미세먼지의 문제를 해결하는 중요사안이 될 수 있다. 그러나 현재 국내의 비산먼지 관련 민원 수중 건설업이 가장 큰 비율을 차지하고 있는 실태로 보아, 국내의 건설현장 비산먼지 배출에 대한 제도적인 관리에 대한 점검이 필요하다. 이에 본 논문에서는 국내외 주요도시별 건설현장에 적용되는 비산먼지 규정을 비교분석한 뒤, 도출한 개선안을 제안하여 국내 건설현장 비산먼지의 제도적 관리에 일조하고자 한다.

국내 건설산업이 우리나라 경제성장을 견인해 오면서 매출규모와 건설기술측면에서 비약적인 발전을 거듭하여 왔으나, 건설공사를 실제적으로 수행하는 건설회사들은 건설업에 내재된 위험요인들에 대해 큰 관심을 기울이지 않아 왔다. IMF위기와 WTO가입을 계기로 건설업에 내재된 불확실성과 위험요인으로 초래되는 경영악화와 사업의 불안정성을 심각하게 경험하면서, 건설위험을 체계적으로 관리하기 위한 시도가 계속되고 있으며, 해외건설공사의 경우 수주영업단계에 적용할 수 있는 위험관리모델이 개발되어 실무에 적극적으로 활용되고 있는 실정이다. 그러나 국내 건설공사의 시공단계에서 위험관리를 체계적으로 수행할 수 있는 절차와 시스템 개발은 이루어지지 않고 있어, 본 연구는 건설현장의 실무자가 쉽게 이해하고 활용할 수 있는 건설현장 실무자들을 위한 건설공사 위험관리시스템 모델을 제안하고자 한다.

Risk Assessment to list possible safety disasters and their probability and severity is the starting point for effective safety management on construction project site. However, the safety managers in owners, construction supervisors, contractors, and sub-contractors still have difficulties in judging the priorities of safety activities and preparing responses to each potential safety disasters. Therefore, this study aimed to suggest a systematic method in assessing safety risk prior to commencement with the agreement of stakeholders. FMECA(failure mode effects and criticality analysis) was selected as a main assessment tool and it was modified according to the characteristics of construction projects and trades. Each risk is, firstly, evaluated with occurrence probability, possible loss and impacts to projects, and detections, and then risk priority number(RPN) is calculated. Subsequently, the managers of each stakeholder discuss the types, timing, and responsibilities of responses as a group decision-making process.

Efficient management of the construction heavy equipment is required to reduce the rate of carbon emissions and on-site accidents. The intelligent excavation system (IES) will improve the construction quality and productivity through information technologies and efficient equipment operation, especially in large earthwork projects. Three-dimensional digitized ground data should be required for identifying the path of heavy equipment and work-site environment. Rapid development of terrain laser scanners (TLS) is more readily to acquire the digital data. This study suggests the '3D ground terrain processing platform (3DGTPP)' including data manipulating module and analyzing module of the scanned data for intelligent earthmoving equipment operation. The processing platform consists of six modules, including scanning, registering, manipulating, analyzing, transmitting, and storing. 3D ground terrain processing platform presented in this study will provide fundamental information for intelligent excavation system (IES), which will increase the efficiency of earthworks and safety of workers in significant.

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.

In order to analyze the impact of fine dust generated from a construction waste intermediate processing site on the surrounding areas, diverse types of samples were collected from inside the site and surrounding areas. The impact analysis results of samples are as follows. (1) Compared to the air quality management standards by the Ministry of Environment, the concentration of fine dust within the site was 30 to 46% for PM10 and 14 to 42% for PM2.5, which was not much different from the general air quality level. (2) It was found that PM10 within the site may have a partial effect on the air quality, but when the blocking facilities in the site, wheel washing facilities at vehicle entry and exit route, and sprinkler during working were maintained, the impact on the nearby area was not high. (3) In the case of PM2.5, its concentration was influenced more by the exhaust fumes from work vehicles than fine dust generated during construction waste processing. Since the PM2.5 concentrations in the site and surrounding area were not much different from the general air quality, there was little correlation with the work impact of construction waste intermediate processing sites. (4) Pb, an indicator of heavy metal components, was within 50ng/m³ in all three sites, which was 10% of the domestic management standard and equivalent to the general air quality level. The complaints from residents in nearby areas were filed using indicators based on visual and experiential information in their daily lives, so even if the survey results of environmental impact by the construction intermediate waste processing site are lower than the standard, nearby residents can feel it better than such numerical information. Therefore, specific activities to reduce find dusts should be continuously continued.

Domestic plant construction sites have a tendency to become bigger, more various and complicated. Moreover frequency of industrial incident is increasing due to short project period, coexistence work condition and using heavy construction equipment. Installing safety facilities and safety training contribute to prevent incident. But mostly incident happens due to workers' unsafe action and wrong work method. Technically, it is very difficult for us to closely manage workers preventing incident. Therefore, the role of foreman who ordinarily works together with his workers is considered more important. Specific execution plan was drawn through industrial incident statistics from Ministry of Labor and questionnaire survey to interest parties(supervisor, safety staff and foreman). If foreman has raised sense of belonging and responsibility by conducting practical safety training for his workers, manages job site and receives proper compensation for these roles, it will be expected that it fully influences incident decrease.

With the growth of information and communication technologies adoption in construction projects, it could be anticipated that more property owners and construction firms will attempt to use electronic gears and gadgets for site monitoring or surveillance purposes. As the construction workers may be the major group of project team members being monitored, from managerial perspectives and for ethical reasons, it is essential to investigate their degree of acceptance on site monitoring systems. Indeed studies on office workplace monitoring suggest that a monitoring system could shape or control the behaviors of employees. With adequate refinements, their research models could be applicable in the construction industry. This paper presents a model for analyzing the antecedences that affect workers' acceptance level on electronic monitoring, and investigating if there is any behavioral change.
