As the Korea construction market has recent3y opened, the needs to restructure the design standard for the technical advancement in design is increasing. Therefore, we proposed the design standard of railway according to the direction, which is presented in this study that analyze the present situation of the previous design standard. The new design standard of railway was tried to definite a limit in each service stage. This design standard will improve the design quality and induce the accumulation of technology. In addition, it will solve the organic contradiction of construction service. As a result, this research will bring the improvement in the design standard and contribute to the development of Korea construction industry.

Standard production unit system has been used as accumulated standard for the cost estimation of public construction projects. However, it is difficult to estimate reasonable cost due to adaptation of a uniform standard and reflect changes in the technology. The purpose of this study is to provide basic data for improvement of standard production unit system through the identifying problems and analysing its influence on enactment and/or revision work of standard production unit system.

민간건축공사의 분양 및 임대 사업에 소요되는 공사기간의 단축은 발주자 측면의 현금흐름의 관리를 위해 중요하다. 그러나 국내 건설산업에는 기준공기의 개념이 정립되어 있지 않아서 공기산정의 기준을 제시하는 데에 어려움이 있다. 이를 해결하기 위해, 공정관리에 관련된 기존의 문헌조사를 통해 공기산정 시 고려되는 영향요인을 파악하고 설문지 조사와 전문가 면담을 통해 최근 완공된 사무소 건축공사의 실적공기를 조사한 후, 수집된 실적공기를 영향요인별로 분석하여 기준공기를 제시하며, 이를 건설 선진국의 실적공기와 비교 및 분석하여 국내 건축공사에 있어서 공기단축의 필요성을 제기하였다.

The objective of this study is to prepare the plans for managing construction noise effectively and solving the popular enmity from construction noise reasonably. In order to carry out this purpose, it covers the efficient improvement plans for adjusting the construction noise regulation standard rationally and managing the automatic noise measuring system which shows the advantage for construction noise management and popular enmity solution due to construction noise. The three alternative plans of the construction noise regulation standard and the recommendation plan including the guideline for installing and managing the automatic noise measuring system are suggested consequently.

This study focus on the suggestion of application manual using assembling reference plane design & standard finish material basis upon material classification code. We see it will function as a tool of a linkage between building design and construction standarization in order to enlarge the applicability of house building material that is produced by the module plan. For a estabilishing of this condition, it is neccessary to link the standardization's result of material--design--construction field. According to this neccessity, we are going to suggest information factor that can make relative business manager easily approach to the standardization practical task.

The domestic process planning generally relies on calculations based on the construction-standard-production-rate. This method requires trial and error practice during the construction phase to deduce the optimized equipment combination for time and cost. Trial and error during construction can lead to cost overruns and schedule delays. Accordingly, this paper suggests an advanced method for establishing a productivity database based on combinations of equipment and also considering site conditions in order to reduce the timely effort for deducing the optimized equipment combination. For this purpose DES (Discrete Event Simulation) model was developed based on the information provided in the construction-standard-production-rate.

The proportion of maintenance work has been increasing due to the recent aging of the infrastructure, but the standardized construction cost estimation standards are insufficient for this. In particular, reinforced concrete structures are being applied to many structures such as buildings and bridges, and various construction methods for maintenance of reinforced concrete structures are being developed and applied. In this study, we surveyed about the current status of the construction method for the maintenance work of reinforced concrete structures and analyze the factors of the revision of the construction cost estimate standard for the reinforced concrete structure maintenance.

Unlike price calculation by cost accounting, which categorizes costs into material costs, labor costs, and miscellaneous expenses to determine the construction budget price, construction cost calculation based on Construction Standard Unit Prices utilizes unit prices extracted from market prices of items from projects already completed to estimate costs of similar construction projects. Although unit price information is collected through construction site surveys to revise these construction standard unit prices every year, but due to the limitations of the site survey method, it is difficult to quickly implement the rapid changes in the construction methods and market prices. As such, an important issue that arose was the identification of work items whose prices need urgent revision. This study conducted research on factors that need to be considered when developing online survey system for monitoring construction site market prices. This study is expected to enhance convenience for users, and provide an efficient data collection and management system for administrators.

In consideration of current circumstances which management activities for safety performance on construction sites are mostly controlled by safety personnel, it is necessary to maintain qualified safety personnel those who are experienced and have adequate ability. This is a major factor in order to prevent any of work related incident in the construction site. However, the existing standard which enforces certain number of safety personnel in the construction site aligning with respective contract amount could lead to difficulties for proactive safety management. So, it is required to get improvement on the existing standard. In nominating the proper number of safety personnel, it would be more efficient to consider the level of risk for characteristic of work itself and the total number of manpower mobilized in respective construction work, rather than to follow the existing standard of manpower ratio as per the contract amount. Hence, this study aims to propose several plans which enable to improve the existing standard for assignment of safety personnel on construction sites.

주당 최장 법정 근로시간을 단축하는 내용의 '근로기준법 개정안'이 통과됨에 따라 근로시간 단축에 따른 근로자 소득감소, 공사기간 연장, 공사비 증가 등 다양한 문제가 발생하고 있다. 특히 다른 산업과 비교할 때, 생산성을 중시하는 건설 프로젝트의 경우 공종에 따라 주 52시간 근무제에 따른 영향의 정도가 더 클 것으로 예상되나 이에 대한 연구는 미흡한편이다. 이에 본 연구에서는 NATM 터널 공사를 대상으로 표준품셈 기반의 표준공정과 굴착 사이클 타임 그리고 공종별 단위 공기를 제시하고, 이를 통해 주 52시간 근무 적용에 따른 실제 작업조의 변화와 이에 따른 표준 공기 및 공사비의 영향을 분석하였다. 분석결과 굴착 공기와 총 공기는 각각 20%, 8.9% 증가하였으나, 굴착공사비와 총 공사비는 오히려 각각 1.2%, 0.5% 감소하는 것으로 확인되었다.
