  • Recently, with the increasing of construction works, large construction equipment are used to reduce the term of work and labor cost in construction field. Therefore, construction equipment noise has caused much annoyance for a number of dweller in nearby construction field and it has become a very serious problem in our living environment. Neverthless, in our country, adequite guidelines for the construction equipment noise are very deficiency because of the lack of basic data and insufficient research works. From this point of view, this study attempts to survey the characteristics of attenuation and propagation of Sand Drain Method in construction field. On the basis of measurement value, we analysed about prediction possibility of Sand Drain Method. This study also present a basic data found a effective plans for Sand Drain Method.

  • Efficient scheduling and resource management are the key factor to reduce construction project budget (e.g., labor cost, equipment cost, material cost, etc.). Resource-based line of balance (LOB) technique has been used to complement the limitations of existing time-driven scheduling techniques (e.g., critical-path method). Optimizing construction alternatives contributes to cost savings while honoring the project deadline. However, existing LOB scheduling is lack of identifying optimal resource combination. This study presents a method which identifies the optimal construction alternatives, hence achieving resource minimization in a repetitive construction by using genetic algorithm (GA). The method provides efficient planning tool that enhances the usability of the system.

  • 건설업은 현재 생계에 직접적인 영향을 주는 임금 관련 문제들로 인해 신규인력의 진입 기피와 기존인력의 이직 등 기능인력 유지에 문제가 발생하여 산업생산기반이 약화되고 있는 실정이다. 이에 본 연구는 신규인력의 유입 증가와 기존 기능인력의 유지를 위해, 현행 임금산정제도를 개선하는 것을 목적으로 연구를 수행하였다. 노동강도가 높은 건설업 최저임금 수준을 산업별, 직종별로 차별화하는 것이 필요하다. 그리고, 휴일근로 및 시간외 수당 등과 같은 명확하게 산정할 수 있는 임금산정기준의 정립이 필요하고, 현재의 퇴직공제부금의 금액 수준을 상향조정하는 것이 필요하다.

  • 현재까지 국내 건설사들은 공법의 개선, 제안 등 다양한 방법을 통해 공사비 원가 절감을 도모하여 왔다. 그러나 그러한 노력들은 각 건설사별로 이루어져 왔으며 성과를 업계 차원에서 공유하는 것으로는 연결되지 못한 실정이다. 따라서 본 연구에서는 최근 완공된 공동주택 1개동 및 지하주차장의 건설 공사비를 기준으로 민간부문에서 적용된 다양한 원가절감 사례들을 조합하여 적용할 경우 기대되는 공사비 원가 절감수준을 분석하였다. 분석결과에 의하면 아파트공사의 경우 기존 대비 3.77%의 공사비 절감을, 지하주차장공사의 경우 7.33%, 그리고 아파트 및 지하주차장을 합한 총 공사비 차원에서는 5.26%의 절감이 가능한 것으로 분석되었다.

  • 현재 건설산업 현장에서 나타나는 숙련공 부족 현상, 고령화 문제, 안전상의 문제로 인한 노무 생산성 저하, 임금 상승으로 인한 채산성 악화, 품직 확보의 어려움 및 시공기술 경쟁력의 약화는 국내 건설산업이 해결해야 할 필수적인 당면과제이다. 한편 위험${\cdot}$유해한 작업환경에서 운용되는 토공장비나 매립지에서의 다짐 및 복토공사, 지뢰 및 폭탄 등에 의한 폭발의 위험이 있는 장소에서의 토공작업, 극한지 공사와 같은 환경에서의 공사수요도 점차 늘어가고 있다. 이와 같은 상황에서 토공의 생산성, 품질 및 안전도를 확보하기 위해서는 지능화된 자동화 장비를 이용하여 효율적으로 작업을 수행할 수 있도록 해야 할 필요가 있다. 따라서 본 연구에서는 지능형 굴삭시스템의 개발을 통하여 작업현장의 안전성을 제고하고 품질, 생산성 및 채산성을 향상시키고 선진외국에 비해 보다 진보되고도 경제성 확보가 가능한 건설 자동화 기술의 구현과 기술개발을 통해 국내 건설산업에 있어 새로운 Market Sector의 창출하고자 한다.

  • To stem the ever-prevalent occurrence of industrial accidents in the construction industry, which is emerging as a social problem, efforts must be invested by various stakeholders. Specifically, among stakeholders, the orderer is at the top of a project's decision-making structure. Therefore, the orderer's awareness of safety and health directly affects the process of securing the safety of the overall construction site. In this light, the present study aims to identify differences in the perceptions of each stakeholder regarding the obligatory safety and health measures for clients that have recently been introduced. In addition, it suggests specific implementation plans in the Korean context. The data used for analysis were collected through a survey targeting stakeholders such as orderers, safety managers, and site managers, and the collected data were quantitatively reviewed by using multivariate analysis methods such as analysis of variance. As a result of the analysis, the introduction of safety and health obligations for the owner was found to be necessary, and the designation and operation of safety and health experts as an action plan was deemed reasonable. The authors expect that the results of this study can be used as basic data for revising the related regulations in Korea. Moreover, as a further study, a review of the effectiveness after improving regulations would contribute strongly to the domain.

  • This technology is able to construct with hardening UREPALT adhesives and TPO URE-Sheet simultaneously using automatic equipments. the benefit of this construction method is that The layer of waterproofing is uniform and defect of construction would be reduced because of no construction joints between UREPALT adhesives and TPO URE-Sheet. Furthermore, this new method could accomplish shortening of construction period, quality control and saving of labor costs. Also the non-exposure waterproofing method would be protected from fire and safe for workers without using a torch.

  • Since the 17th century, the finance for the government construction was demanded unlike the early chosun dynasty. It was consequent upon a transition in the supply method of materials and labors for the construction. The government construction being enforced in chronic financial difficulties had to undergo lack of funds. Especially, a rising construction cost by purchasing lots of materials including wood, and by employing labors weighted the difficulties. In order to put forward a construction, new and various efforts besides diversification in sources of finance ad been looked for. The efforts were driven in three parts which were to be the management of labor and materials, and the way of construction execution. As a result of spending a great effort to save cost, an extinguished improvement in the way of construction execution came out with 'Injungjeon-yeongkweon' in the year 1805.

  • Domestic construction industry has experienced many difficulties as it has been on a downward. It's a way that active modular structure market to solve this problem. However, as Modular structure technical standard in Korea is in the early stages, our modular factory maufactured rate is almost 40% lower than overseas. Besides, there is less design diversity so it just applies for a few buildings like low-rise building and general group barrackes. To deal with these problems, it is essential to modulating the equipment which can improve the production rate. This will help to ensure the quality, shortening of the construction period, the reduction of labor costs. We have defined the name of segmented by each installation location of the equipment to modulating equipment. And it was examined the suitability of the modulating of the location-specific utility system. The results of the analysis are discussed on the page.
