For a few recent years, KECA(Korea Electrical Contractor Association) has promoted a project to establish an electrical construction specification called Master Spec. This paper analyses the characteristics of standards-making process of the Master Spec. as an umbrella technical standard in electrical construction industry in Korea. This paper argues that even if the Master Spec. is recognized to be technical standards, the standards-making process involves both technical and social practices when viewed from social construction theory and governance perspective. This aspect of social practices in technical standards making should be well understood because various stakeholders in terms of interests, resources, and motives try to influence the process positively and negatively. KECA in responsible for enactment of the Mater Spec. should be very thoughtful in building consensus first of all among electrical contractors, managing relationship with concerned government officials, and dealing with potential deviant groups as well as in pooling expertises and developing technical knowledge needed for designing technical specification.

Urban transit is one of the most effective ways for efficient operation and construction of an urban transit by composition system which is liked originally such as rolling-stock, power, signal and infrastructure. Urban rail transit system is running in domestic, imports major equipments from advanced countries and setup for maintenance. But it takes long time because it does each organizations and lines. Also, signal, power and track system apply different standard by each construction organizations it causes an increasing construction of cost accordingly it desperately needs a systematic countermeasure. Therefore standard specification of urban transit have been establishing and operatingfor efficient operation of urban transit and base technology security that is populace ride to become a base of state economy. After track, power and signal system will be announced. Standard specification become more, the importance of administrationof standards is emphasized more. Specification administrator’s the importance which use a computing support tool recently in railroad part in embossed and is predicted to be more such forward. Therefore we propose the effective method of management with track, power signal system by constructed data-base system.

The purpose of this study is to retrospect the establishment process of specification of modern factory-made traditional Korean roof-tile. Its another purpose is to analyze the specification of watong(瓦桶, a wooden molding frame for roof tile making) which is recorded in the literature of Joseon dynasty. The results of this study are as follows. : First, the specification of modern factory-made Korean roof-tile that currently used was established in 1978. And it did not succeed old traditional specification. Second, in case of construction or repair of main building of palace, it was a principle to use Daewa(大瓦, the big size roof-tile). And Sangwa(常瓦, the ordinary size roof-tile) was used when needed. Also, Jungwa(中瓦, the middle size roof-tile) was used regardless of the size of group building. And Sowa(小瓦, the small size roof-tile) was used in house and wall of royal tomb. Third, it is needed to establish a specification of traditional handmade roof-tile based on the specification of watong through research of the litterateur. So, a standard draft for this was proposed. Finally, one can find the significance that this study has tried to find a specification of traditional roof-tile that can be applied to construction or repair of cultural heritage.

When building with concrete in cold weather, an insulation method of heat curing must be determined, and a holistic curing plan that considers the characteristics of structures, the heat loss coefficient of a curing sheet, the joint condition of the curing materials and the quantity of heat produced by a heating apparatus is an essential prerequisite for protection against early frost damage. But on a number of national construction sites, there have been serious problems in cold weather concreting due to the unreliability of the information obtained from practical experience. In the construction field in Japan, there is a specification for heat curing prepared by Japanese Architectural Society, which provides an equation for calculating heat quantity. It is also necessary to adopt a detailed specification for a standard heat curing method that is applicable to all national construction sites. In this study, the effect of bubble sheets on the economic feasibility of cold weather concrete is investigated through a comparison with the blue sheets commonly prescribed in national construction sites. In conclusion, this study found that bubble sheets had the effect of reducing the cost of curing materials and the fuel cost consumed by a heating apparatus, compared to the use of blue sheets.

In this paper, standard specification of heat curing section of cold weather concrete between Korea and China were compared. First, Korea concrete specification (KCS 14 20 40) stipulates that the application period is less than 4℃ per day or less than 0℃ per day right after pouring, but in China, the outdoor daily average temperature is less than 5℃ for five consecutive days. This is believed to be due to the difference in temperatures between Korea and China in winter. Next, in the case of Korea, KCS do not show that the concrete temperature in curing should be 5℃ or higher to prevent early frost damage and obtain the minimum required compressive strength. On the other hand, in the case of China, the specificaion does not show that the curing method is selected based on the concrete surface coefficient after considering the outdoor temperature. In addition, in Korea and China regulation, the temperature of the space during thermal curing was shown to be similar.

The most design criteria and specifications in Korea utilized to ensure appropriate quality are based on process and prescriptive criteria determining materials, measure and methods. It has many problems including a loss of competitiveness resulting from inhibited creativity of the contractors. The performance-based specifications focused on final product are being proposed, but have difficulty in adapting to the architectural field. In this study the hybrid specification prototype for curtain wall construction was suggested. The specification framework was presented through analysis of linkage between the performance and prescriptive specification cases. Based on the survey with practitioners, the performance inspection process and the sample specification were developed by identifying the essential performance test timings. The applicability of the specification prototype was evaluated by interviews with experts. It was found that the prototype was active and a progressive supporting tool which could support to secure phased performance during construction as well as final performance.

Although the Korean construction industry has risen rapidly, the quality of the buildings is not met with the industry standard compared to the potential of the technology development and the cost of maintenance has been increased. The user's request for quality have been increased, but in the current building construction, the contractors only follow the specifications of design, material and technology, and their main concern is whether they are in right track with the specification or not. Thus, the necessity of developing technology has been ignored and sufficient opportunities for the development have not been provided as well. In the developed countries, in contrast, the quality assurance and the payment regulation system has been utilized for the active response to the changes of users' request. As a result of this, the maintenance cost has been decreased and the development of construction technology has been improved. Therefore the pay adjustment system is needed to create the improvement of the quality of the buildings by the contractors' earnest building construction. In order to introduce the pay adjustment system suitable to the Korean construction industry, this study presented the logical method of adjusting the construction cost and making payment with the pay adjustment index that is created based on the result of the performance test, after making a set of the indicators of the building performance standard and applied them to the targeted building.

A construction temporary work is main process and importance trade section. A technology system of construction temporary has very low availability of field works and needs improvements in Korea as construction site has a quick response about new requirements. This study reviews literature researches and can verify that changes to a comprehensive technology system for construction site. In addition, it suggests a breakdown structure of new standards for temporary construction technology based on views of construction site managers. Meanwhile, temporary construction technology in Korea has changed with a specification of construction temporary work which had been revised in 2014. However, the revision is merely dividing the design and building off of construction temporary technology. It is lacking in many ways to change this in a new standard system for temporary construction technology. Henceforth, it needs to develop a standard system for temporary construction technology and a professional system that is appropriate for different purposes by detail trade sections.
