동시공학(Concurrent Engineering)은 80년대 초부터 효과적으로 사용되어 왔지만 널리 사용되지는 못했다. 동시공학의 효과는 비용절감, 시장조사시간의 단축, 품질의 개선 등 다양하게 표현 될 수 있다. 웹기반의 네트워크가 구성되면서 동시공학의 장점을 더욱 개선되었다고 할 수 있다. 여러 장소에서 시간에 관계없이 동시에 접근할 수 있기 때문이다. 웹 기반의 시스템에서 많은 기업들이 동시공학의 방법을 사용함으로서 이점을 발견할 수 있다. 본 논문은 실제 미국의 건축회사를 사례로 동시공학의 장점을 살펴보았다.

건설현장을 비롯한 전산업분야에서 추락, 폭발, 화재, 감전, 독성물질 중독 등이 빈번하게 발생하고 있으며 이것은 물질적, 인적, 자원손실 뿐만 아니라 각종 노사분규나 작업효율의 저하로 이어지고 있다. 이러한 산업재해 예방에 대한 연구로서 건설업을 중심으로 중대 재해 사례연구(1), 안전관리 비용 절감(2), 그리고 건축현장 사고의 Human Factor(3)등에 대한 연구보고가 제시되고 있다. (중략)

성능중심의 건설기준을 개발하고, 성능계약제도 도입방안을 구축함으로써 시설물의 성능을 향상시키고, 생애주기비용(LCC)을 절감하며, 설계 및 시공자의 기술개발을 유도하는 것이 필요하다. 본 연구에서는 건축전기설비분야의 성능기준 개념과 외국의 도입사례를 살펴보고, 성능기준 개발 대상 및 범위를 설정하고 성능 기준 개발을 위한 접근방법을 도출하였다. 앞으로 국제 경쟁력 확보를 위해서는 성능중심의 건설기술기준 적용이 필요하다.

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.

In general, fire resistance is determined through the building' uses and stories. But recently a fire engineering design that is done by the calculation of design fires from the fire cell and an evaluation of stabilities for structural behavior at fire condition have applied to almost of countries as a major alternative against a prescriptive fire design. To adopt and utilize the fire engineering design into Korea, at first, we evaluated structural stability of 21st stories steel residential building at fire condition through fire engineering design and secondly the fire protection cost was analyzed with fire engineering design method and the prescriptive one, respectively. No fire protection materials for satisfaction of building law at structural members such as columns and beams were needed and about 90 % of fire protection cost was saved.

In this paper, We implement a power-saving and efficient measures in buildings using the smart-meter. In order to save electric power energy, We propose an improved automatic power-factor controller(APFC) and demand control measures. This is achieved by controlling directly circuit breakers and the capacitor bank feeders in real time via a two-way smart-meter's ICT skills. Improved APFC is minimizing installation costs by series-parallel connecting heterologous capacitors to form a more diverse capacitor banking and controlling using the smart-meter. In order to suppress the demand power, We have designed a smart-meter with communication functions using Atmel's AVR465 and tested an operated lodging building for 24-hours. As a result, We made sure to always retained more than 95% power factor and did not occur over compensation.

Modular construction is recognized as a construction method with various advantages, such as shortening the construction duration, achieving quality control through factory production, ease of maintenance, and reduced construction costs due to reduced weight of materials. However, despite efforts by the modular industry and government to activate modular construction, it has rarely been established in the domestic market. Currently, there are technical limitations to the modular construction fire resisting technology applied to general buildings. The lack of access to modular construction fire resistance regulation is considered a major factor. In this study, the current status and problems with modular construction fire resistance regulation, a significant hindrance factor, were considered to activate modular construction. This study is intended to present a direction for institutional improvement in modular construction fire resistance and a direction for research and development.

The South Korean government plans for a 37 % reduction in CO2 emissions against business as usual by 2030. Subsequently, the Ministry of Land, Infrastructure and Transport declared a 26.9 % reduction target in greenhouse gas emissions from buildings by 2020 and established the Green Standard for Energy and Environmental Design (G-SEED) to help improve the environmental performance of buildings. Construction companies often work with consulting firms to prepare for G-SEED certification. In the process, owing to inefficient data sharing and work connections, it is difficult to achieve economic efficiency and obtain certification. The objective of this study was to develop an economic model to assist contractors in achieving the required G-SEED scores for materials and resources. To do this, we automated the process for material comparison and selection on the basis of an analysis of actual consulting data, and developed a model that selects material alternatives that can meet the required scores at a minimum cost. Information on materials is input by applying a genetic algorithm to the optimization of alternatives. When the model was applied to actual data, the construction cost could be lowered by 79.3 % compared with existing methods. The economical material selection model is expected to not only reduce construction costs for owners desiring G-SEED certification but also shorten the project design time.

When managers predict exact construction cost at early stage and design phase, they can reduce construction cost in a more efficient way than to predict at construction stage. But present of public construction cost estimation and management almost after the construction documents design phase. Therefore, construction cost management in the early stage and schematic design phase to generally use approximate estimating is not correct. Accordingly, this study analyze problem of current cost estimating method and a concrete cost plans make using case information of actual cost to analyze in schematic design phase. Possible to check going on the suitable design, this study conducts the preliminary research for the development of cost estimating model.
