건설산업내 상생을 위한 정부의 중소기업 보호 정책에도 불구하고, 위축되어 가는 건설시장으로 인해 대·중·소기업간 수주양극화, 중소기업 및 지역기업의 수주 경쟁력 약화 및 수익성 약화 등의 문제는 여전히 개선되지 못하고 있는 실정이다. 미국 건설산업내 중소기업 및 지역기업에 대한 발주우대제도, 입찰우대제도, 지역기업 활용을 중심으로 건설산업 생태계 내 상대적 약자인 중소기업, 지역기업, 사회적약자소유기업 등을 위한 미국 연방 및 주정부의 정책 및 제도를 고찰하고, 이를 통해 바람직한 중·소기업 보호 및 경쟁력 강화 정책 방향 재고를 위한 국내 중소기업 보호 관련 정책에 시사하는 바를 도출하였다. 결론적으로 물량 배분을 기반으로 하는 국내 중소기업보호 관련 정책과는 달리 미국의 중소기업 및 지역기업 우대 제도는 해당 기업들을 일정비율이내에서 우대를 하되 공정경쟁 원리를 동시에 수용함으로써, 중소기업 및 지역기업 보호와 동시에 해당 기업들의 경쟁력을 강화 할 수 있는 방향에서 정책을 운용하고 있다. 따라서 향후 국내 중소기업 및 지역기업 보호 및 경쟁력 강화를 위해서는 일정부분 보호하는 동시에 중소기업의 경쟁력을 강화할 수 있는 방향으로 관련 제도를 정비할 필요가 있을 것으로 판단된다.

This study is to analyse the causes of accident in small and medium-sized construction sites and to provide prevention strategies and system improvement guidance. Although occupational safety and health act regulates the standards and installations of temporary structures, about an half of construction accidents were caused by poor temporary structures such as guardrails, scaffolds, work platforms, etc. It investigated 51 construction sites which is located in metropolitan area by asking a series of questions including their knowledge about regulations and opinions about prevention strategies. The result shows that many of the respondents do not have sufficient understandings about the regulations, and it implies that education and training must be reinforced in order to enhance the safety-awareness and to develop the comprehension of regulations.

The smart factory is an important system that can reduce defects, maximize productivity, and respond to customer needs, from the labor-intensive era of traditional small and medium-sized manufacturing companies through the automation era to CPS using ICT. However, small and medium-sized manufacturers often fall short of the basic stage due to economic and environmental constraints, and there are many companies that do not even recognize the concept of a smart factory. In this situation, to expand the smart factory of small and medium-sized enterprises, the project to support the establishment of a smart factory for the win-win between large and small enterprises. The win-win smart factory construction support project provides a customized differentiation program support project according to the size and level of the company for all domestic manufacturing SMEs regardless of whether or not they are dealing with Samsung. In this study, we analyze the construction status and introduction performance of companies participating in the win-win smart factory support project to find out whether they have been helpful in management and to find efficient ways to improve support policies, and to suggest the direction of continuous support projects to improve the manufacturing competitiveness of SMEs in the future.

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.

중소건설업체는 열악한 경영상태 전문인력 부족, 기술력 부족 등의 여러 문제로 인해 그 기반이 매우 취약하다. 이린 상황에서 IMF 이후 대형건설업체들의 수주난과 경영 악화는 대형건설업체의 하도급을 수행하는 중소건설업체에도 전가됐으며, 이에 중소건설업체의 생존을 위한 전반적인 변화와 정보기술 도입을 통한 경쟁력 확보가 요구되고 있다. 본 연구는 중소건설업체의 프로젝트 관리방안 측면에서 중소건설업체의 특성과 기존 대형건설업체 및 상용 SI업체에서 개발한 정보관리 시스템을 분석하여 중소건설업체를 위한 프로젝트 정보관리체계를 구축하고 이를 관리하는 지원시스템 모델을 제안하고자 한다. 이를 통해 중소건설업체의 프로젝트 정보관리 능력을 향상 및 생산성 향상을 통한 경쟁력을 확보할 수 있을 것으로 예상된다.

This study aims to present a method to evaluate the relative risk of failure due to liquefaction of domestic small to medium-sized earthfill dams with a height of less than 15 m, which has little information on geotechnical properties. Based on the results of previous researches, a series of methods and procedures for estimating the probability of dam failure due to liquefaction, which calculates the probability of liquefaction occurrence of the dam body, the amount of settlement at the dam crest according to the estimation of the residual strength of the dam after liquefaction, the overtopping depth determined from the amount of settlement at the dam crest, and the probability of failure of the dam due to overtopping was explicitly presented. To this end, representative properties essential for estimating the probability of failure due to the liquefaction of small to medium-sized earthfill dams were presented. Since it is almost impossible to directly determine these representative properties for each of the target dams because it is almost impossible to obtain geotechnical property information, they were estimated and determined from the results of field and laboratory tests conducted on existing small to medium-sized earthfill dams in previous researches. The method and procedure presented in this study were applied to 12 earthfill dams on a trial basis, and the liquefaction failure probability was calculated. The analysis of the calculation results confirmed that the representative properties were reasonable and that the overall evaluation procedure and method were effective.

90년대 이후 전 세계적으로 지식경영(Knowledge Management : KM)에 대한 관심이 고조되고 있다. 특히 기업의 시장가치 중 지식자산이 차지하는 비중이 높아짐에 따라 한국의 건설 분야도 90년대 중반부터 대기업을 중심으론 지식경영을 도입하고 있다. 그러나, 중소${\cdot}$전문건설업체의 경우에는 기업의 재무 및 조직적인 이유로 지식경영에 대한 이해와 정보화에 뒤쳐지고 있는 실정이다. 더욱이, 건설 분야에서 중소${\cdot}$전문건설업체가 차지하는 비중이 매우 높게 나타나기 때문에 이들의 기술 수준이 건설공사의 품질과 직결된다고 해도 과언이 아니다. 따라서, 본 논문에서는 회사의 가치와 경쟁력 향상을 위해서 중소${\cdot}$전문건설업체들의 여건에 적합한 지식경영 전략 즉, 지식경영 도입 방안을 제시하고자 한다.

오늘날 건설기업은 정보화, 국제화로 인해 국내뿐만 아니라 해외 건설기업들과도 경쟁을 해야 하는 상황이다. 무한경쟁에서 살아남기 위해서 건설산업의 특성을 반영한 타산업과는 다른 체계적인 성과관리가 필요함에도 불구하고, 국내건설기업의 많은 비중을 차지하는 중소건설기업들은 자체적인 성과관리시스템 구축 및 운영이 미비한 실정이다. 이러한 시스템 기반이 미비한 중소건설기업을 위한 시스템 구축에 앞서, 현존하는 건설 성과관리시스템을 분석하여 시스템 구축에 필요한 핵심요소들을 도출하고자 하였다. 이에 영국의 KPI, 미국의 CII BM&M, 칠레의 NBS-Chile Project, 브라질의 SISIND-NET Project 사례들을 분석 하였다. 본 연구에서는 이들 해외사례분석을 통해 도출한 핵심 요소를 바탕으로 효과적인 성과관리 전략인 벤치마킹을 이용한 성과관리시스템의 개념모델을 제안하였다.

Measuring management is an important part of preventing the collapse of retaining walls in advance by evaluating their stability with a variety of measuring instruments. The current work of measuring management requires considerable human and material resources since measurement companies need to install measuring instruments at various places on the retaining wall and visit the construction site to collect measurement data and evaluate the stability of the retaining wall. It was investigated that the applicability of the current work of measuring management is poor at small and medium-sized urban construction sites(excavation depth<10m) where measuring management is not essential. Therefore, the purpose of this study is to develop a laser sensor-based hardware to support the wall displacement measurements and their control software applicable to small and medium-sized urban construction sites. The 2D lidar sensor, which is more economical than a 3D laser scanner, is applied as element technology. Additionally, the hardware is mounted on the corner strut of the retaining wall, and it collects point cloud data of the retaining wall by rotating the 2D lidar sensor 360° through a servo motor. Point cloud data collected from the hardware can be transmitted through Wi-Fi to a displacement analysis device (notebook). The hardware control software is designed to control the 2D lidar sensor and servo motor in the displacement analysis device by remote access. The process of analyzing the displacement of a retaining wall using the developed hardware and software is as follows: the construction site manager uses the displacement analysis device to 1)collect the initial point cloud data, and after a certain period 2)comparative point cloud data is collected, and 3)the distance between the initial point and comparison point cloud data is calculated in order. As a result of performing an indoor experiment, the analyses show that a displacement of approximately 15 mm can be identified. In the future, the integrated system of the hardware designed here, and the displacement analysis software to be developed can be applied to small and medium-sized urban construction sites through several field experiments. Therefore, effective management of the displacement of the retaining wall is possible in comparison with the current measuring management work in terms of ease of installation, dismantlement, displacement measurement, and economic feasibility.
