This study presented a new NOS model through the following suggestions to apply the construction work planing and management to NOS(Network Operating System). First, This study presented CIMS(construction information classification system) reflected the characteristics of facility classification - functional component classification - functional component classification - work classification - resource classification. Based on this system. this study presented how to establish PMMB(performance measurement management baseline) with proposed master target equation which analyzed the trend of performance measurement management baseline and proposed work target equation which analyzed the execution results. Finally, this study presented NOS model that can be applied to fixed price method and cost plus fee method through the theoretical verification of executive performance analysis method.

As high-rise and irregularly shaped building structures have become a trend at home and abroad, BIM technology is now being developed and accepted widely. However, the BIM data and information generated in the design phase cannot be actively reutilized in the construction stage. This is because the major interests of construction companies include working process and cost estimation, while there is not usually enough BIM data created to support these activities. In order to resolve this issue, we need to set up BIM modeling guides that make it possible to extract correct quantity take-off from BIM data. Quality checks are also necessary to ensure that the resulting BIM data is correct. This study suggests ways of securing BIM quality for correct quantity take-off, which is critical for BIM technology applied to the building construction process and its cost estimation.

본 터널 붕락 사례 연구를 종합적으로 분석해 볼때, 시공 공정 중에 발생 가능한 붕괴 및 붕락은 앞서와 같이 과거의 여러 사례들을 토대로 분석함으로서 예측 할 수 있지만, 시공 외적인 요인에 대해서는 사실상 조사, 설계, 시공 중의 오류에 의해 발생되는 것이기 때문에 파악하기 어렵다. 본 터널 붕락사례를 통해 원인을 분석 정리 하면 다음과 같다. (1) 불규칙한 지반구조적 원인 대부분의 터널 붕락을 일으키는 불규칙한 지반구조는 과거 지반구조의 침식 또는 대규모 지반운동 등 지반구조의 급속한 변화에 기인한 것이다. 터널 시공전에 면밀한 사전 지반조사와 선진 보오링 등으로 정확한 지반구조를 파악한다면 이로 인한 터널 붕락은 최소화 시킬수 있다. (2) 기획과 설계단계에서의 오류 충분치 못한 지반조사에 의한 설계 및 부적절한 시공자재 사용등으로 터널 붕락이 발생 될수 있다. 터널 굴착 주변 지반조건과 이러한 지반조건에 적합한 터널 굴착 및 보강공법 등이 터널 설계시 심도있게 검토되어야 할 가장 중요한 요소이다. (3) 시공 및 관리에서의 오류 경험이 부족한 터널기술자의 현장 감독과 현장에서 수집되는 각종 계측자료의 신뢰성 부족과 결과의 재적용 미흡으로 효율적인 계측 및 지반정보를 활용한 정밀 시공이 이루어지지 않는 것도 터널 붕락의 중요한 요인으로 분석되었다. (4) 현장관리 조사서의 표준화 부족 터널굴착공사중 붕락이 발생된 현장의 막장조사결과를 보면 조사자가 임의로 표시를 하여 각 터널별 막장조사결과가 매우 상이할 뿐만 아니라 각 터널별로 기재방법, 양식이 달라서 실제 원인분석에 활용하기가 어려운 것으로 분석되었다.

This study aims to establish the performance standard for natural type landscape stone GFRC. The required performance such as material performance, structural safety performance, durability performance, and landscape performance were selected through an examination of domestic and overseas performance related references and examples, and through the questionnaires obtained from 40 experts, and the verified items and performance standards were proposed. Among the required performances, the material performance(glass fiber content, air-dried gravity), structural safety performance(flexural strength, compressive strength), durability performance(crack, corrosion resistance), and landscape performance(texture, efflorescence) were selected through the questionnaires obtained from the experts. In the case of material performance and structural safety performance with the corresponding standards that existed, final performance evaluation standard was proposed by conducting a test and comparing it with the existing standard sample, and in the case of durability performance and landscape performance on which standard does not existed, they were verified by measuring directly through field examination of formative landscape items such as artificial waterfall etc. In this study, performance standard for the material on natural type landscaping rocks GFRC and items which can be evaluated after construction such as material performance, structural safety performance, durability performance, landscape performance, and so forth were proposed, however, follow up study for pro-environmental and ecological performance standard which were recently gaining force would be required through a continuous monitoring for the construction samples afterwards.
