표준품셈 487개 항목이 제·개정됨에 따라 건설공사의 예정 가격이 전반적으로 하락할 전망이다. 특히 올해 새로 도입될 표준품셈 상시관리시스템이 작동하면 내년 표준품셈 개편폭은 더욱 확대된다. 건설교통부는 지난 1월 4일 기계설비 등 5개 공종에 걸친 487개 표준품셈 항목을 신설·개정했다고 밝혔다. 이번 개편의 특징은 기존 기관별 요구사항을 단순 반영하는 것이 아니라 건교부가 직접 목표량을 설정해 직접 발굴했고 기계설비, 토목터널 부문이 집중 개선된 점이다. 기계설비 부문의 경우 밸브 및 콕류, 신축이음쇠, 잡철물, 방열기, 위생기구, 소화전 등의 항목이 대폭 개정됐다. 이번 개편에 이어 전체 표준품셈 2,460개 항목 가운데 503개 항목이 추가로 조정돼 내년 초 공표된다. 특히 표준품셈 상시관리시스템이 올해 상반기 가동되면 내년 초 공표될 항목은 이보다 더욱 늘어날 전망이다. 정부의 시스템 운용방침이 당초 계획된 2개년 목표치(990개 항목) 외에 추가 항목을 발굴하는 것이기 때문이다.

Construction equipment cost is critical to estimate the total construction costs, particularly in large and complicated projects. Public construction projects are typically estimated using the Poom-Saem which includes hourly rates for workers and equipments. Despite its importance, the construction equipment cost may not properly reflect the current market value because it is being updated every six years at most. To keep the data for construction equipment cost estimation up to date, it is highly recommended to use the standard market price that is reported each year by the Ministry of Security and Public Administration (MOSPA). However, there is still a wide gap to directly adopt the standard market price for updating the construction equipment prices. Therefore, this paper suggests an effective way to develop an ordinary management systems for updating construction equipment prices in the Poom-saem based on the standard market price.

The current cadastral business is being operated by conversion to a digital cadastral management system through computerized registers (land register and forest land register) and maps (cadastral map and forest cadastral map). Digital surveying methods, such as GPS surveying and electronic plane table surveying, are also used for cadastral surveying. At present, fees for cadastral surveying are calculated based on a standard pursuant to the Construction Standard Production Unit System and an announcement by the Ministry of Land, Infrastructure, and Transportation. In many cases, however, the cadastral surveying fee system announced at present fail to apply the digitalized environment depending on the item. This study sought to analyze the cadastral surveying fee system that requires improvement in the rapidly changing digital cadastral management environment, and to prepare a basis to establish a cadastral surveying fee system suitable to the digital environment by suggesting an improvement method for such system. As a result of the study, the following suggestions were made: a method of changing to terms suitable to the digital environment based on the current status analysis; preparation of a new estimation system regarding new estimation items; and re-survey of an estimation system of cadastral confirmation survey and preparation of an estimation system.

The amount of labor input in a construction project is used as source data to estimate construction cost and to understand the productivity of the construction industry. However, there is a significant difference between the standard of estimation and the actual amount of labor input, and a plan is needed to resolve this problem. For this reason, to establish a system with which the actual amount of labor input can be inputted in a more accurate and simpler manner, a new method is proposed in this study. In the new method, a digital pen is used to minimize the difference from traditional handwriting on paper using a pen, and eliminate the redundant input of information. This study is expected not only to reduce the actual amount of labor input but also to contribute to the productivity of construction cost estimate through the sharing or utilization of the information on the web.

There are two kinds of cost estimate system in construction in china. Quota valuation model is a traditional cost estimate system under the unity of quantity and price, which is easier and has been used for decades. But the Quota valuation model becomes increasingly unsuited to the needs of society with the development of market economy. To meet the needs of China's market economy development and construction works in the field of international cooperation, the Bill of Quantities valuation model was introduced in 2003. However, there are still many shortcomings and deficiencies in the course of implementation of Bill of Quantities valuation model. In addition, interest in the Chinese construction market continues to increase in Korea due to the recent new North Korean policy and China's the Belt and Road policy. This paper aims to examine the cost estimate system of public construction works in China, and to provide basic data for deriving future improvement plans by comparing and analyzing it with standard cost estimate system in Korea.

As aged infrastructures have been increased, the importance of accurate maintenance costs and proper budget allocation for infrastructure become prominent under limited resources. This study proposed a mapping algorithm between representative defects, repair methods, and the estimated maintenance costs for concrete bridges. In this regard, using BMS (Bridge Management System) data analysis, bridge repair methods were classified and matched with defects according to their locations, types, and sizes. In addition, the maintenance costs were estimated based on the amount of work-load and quantity per unit using CSPR (Cost Standard Production Rate). As a result, the level of accuracy was an average of 85.1 % compared with the actual bill of quantity for Seoul bridge maintenance. The accuracy of maintenance costs is expected to be enhanced by considering the various site conditions such as pier height, extra charge conditions, additional equipment, etc.

Cost estimate system Will be changed from the prime. cost calculation to the historical cost data because the present system has some problems. In this situation, each owner should prepare his own cost estimate system based on the historical cost data. In this study, the standard work items were classified and the criteria of their work amount computation were established for rural improvement projects. And also the historical cost data were collected in all range of rural improvement projects, and the database system, "HICOMS" (HIstorical COst data Management System) was built. In order to test the applicability of the HICOMS, standard work cost and contractor cost were compared. The results by HICOMS showed high significance and it was concluded that the HICOMS could be applicable for the cost estimate of the rural improvement projects. projects.

The importance of construction waste reusing and recycling is becoming increasingly large because the demolition industry is in current trend to pursue for sustainable growth. As the considering situation of the domestic housing construction and existing house, a scale of demolition industry is expected to be increased continuously. But the related cost regulations that are used in tendering in the demolition industry are insufficient, also the computer system for estimating the demolition costs have not been developed yet. Therefore, in this study suggests man-hours of 21EA items which are utilized to estimate demolition cost and work rate of $1.0m^3$ breaker which is used mostly in domestic demolition industry after analyzing a case study for deconstruction works. The computer system is developed for the estimating demolition cost easily, which are including five modules such as a project information, a unit cost management, a standard unit cost table, a bill of quantity, and a reporting system. This computer system is possible to apply for estimating cost of both mechanical demolition and blasting demolition. The biggest advantage of this system is to estimate cost to utilize standard WBS which is linked with standard unit table and each DB. This can help unskilled users use easily for it.
