In spite of various approaching method to satisfy with the owner's requirements in schematic design phase, it is insufficient to evaluate intermediate process of design arithmetically with participating in design process. So the numerous changes of design after completion of design development cause a lot of loss to the design company. The designer arranges owner's requirements to prevent from this loss at the initial stage of schematic design phase systematically and lets owner and stakeholder to evaluate the value of schematic design to satisfy with owner's and stakeholder's requirements. If the evaluated value for schematic design is above a definite value index, the next design phase should be advanced. By this method, the design company can reduce the additional expenses remarkably by preventing with re-design which is occurred by not reflecting owner's intention or by changing owner's intention. Also the designer have the owner to evaluate the result of design and construction. The designer let the owner know whether the owner's requirement should well have been reflected on drawing or not. There is a strong point to be able to minimize the criticism which can be occurred after completion of construction by evaluating for owner's satisfactory degree and by having owner and designer confirm the result of design and construction arithmetically. This paper presents that the loss of design company can be minimized by going over at next step if the value is over a definite value index after evaluating value for each design from design process.

2회에 걸쳐 연재된 건축사지 '테마기획/지역건축탐방-북한'편은 북한지역 건축에 대한 자료와 정보가 부족한 가운데에서도 북한의 건축을 하나의 '지역문화라는 시각에서 이해할 수 있는 장을 열어주었다. 건축에 관련된 북한 간행물이 극히 적은데다 일반인의 접근도 극히 제한되어 있어 많은 자료가 탈북자들에 의존해야 했던 현실이 좀 안타까웠다. 그러나 남북정상회담을 통해서 4대합의 사항의 6.15선언이 발표된 이 시점에서 볼 때 건축분야에서도 통일을 대비해야하는 긴급한 현실적 요구가 있으며 따라서 이 연재가 준 의미는 크다. 더구나 북한건축에 대한 공식적인 공개논의가 남쪽에서 한번도 없었던 점을 생각하면 이 연재가 주는 비중은 더욱 크다. 그러면 어떻게 통일을 대비할 것인가? 이 연재를 읽으면서 느꼈던 점들을 나름대로 정리해본다.

The purpose of this study is to analyze user requirements of photovoltaic generating facilities for detached houses. For the analysis, 202 households that installed photovoltaic generating facilities to conduct a survey. According to the survey results, users mainly demanded 'Reduction in self-burden amount' and 'Maintenance Services.' In addition, when conducting 'Education for photovoltaic generating facilities', they highly wanted to participated in it. Results on the installation status of photovoltaic generating facilities are as follows: Of locations where photovoltaic generating facilities are installed, the most households installed them on the roof, 54%. As for the angle in which photovoltaic module is installed, the range of $25{\sim}35^{\circ}$ was the most common and in the case of installation direction, southern exposure accounted for the rate of 93%. The monthly average generation of households surveyed is approximately 320kWh. Research on technology and policy to address user requirements shown in this study is deemed necessary in the future.

The market for compact houses is growing due to the demand for floor plans prioritizing user needs. However, clients often have difficulty communicating their spatial requirements to professionals including architects because they lack the means to provide evidence, such as spatial configurations or cost estimates. This research aims to create a framework that can translate sketched data-driven spatial requirements into 3D building components in BIM models to facilitate spatial understanding and provide building performance analysis to aid in budgeting in the early design phase. The research process includes developing a process model, implementing, and validating the framework. The process model describes the data flow within the framework and identifies the required functionality. Implementation involves creating systems and user interfaces to integrate various systems. The validation verifies that the framework can automatically convert sketched space requirements into walls, floors, and roofs in a BIM model. The framework can also automatically calculate material and energy costs based on the BIM model. The developed frame enables clients to efficiently create 3D building components based on the sketched data and facilitates users to understand the space and analyze the building performance through the created BIM models.

Building industry clients are suggested to clarify requirements and needs properly at the pre-project stage. According to these they can develop options to meet their needs with considering their resources and business case. At this stage, they make decisions while professionals in the industry are not involving. This process is called client briefing at the pre-project stage. However, client briefing is not a discrete process only conducted at this stage; various clients briefings should be performed over a project lift cycle. The client briefing at the pre-project stage is more important than others as the value for the clients is clarified at this stage - they may not be satisfied for the project results even when the project is finished on time within budget if the value itself is incorrectly defined. Given that the client briefing is important as stated, this paper aims to review theory on client briefing focusing those at the pre-project stage. As a part of research, a prototype workshop for client briefing is held and findings from it are summarized. Finally, suggestions for conducting client briefing in Korea are presented in terms of directions of relevant research, systems in the industry and points that clients or client briefing consultants should consider.

과연 콘크리트 구조물에 있어서 누수 균열은 문제가 되는 것일까？ 이에 대해 설계, 구조 시공, 재료(콘크리트), 방수, 품질 및 안전의 관련 전문가는 여러 가지 이견을 말하고 있다. 또한 콘크리트 구조물에 관계하는 발주자, 건축주, 사용자, 시공자의 입장도 상황에 따라 다르게 해석하고, 평가하고 있다. 예를 들면 일반적으로 발주자(건축주 등)는 시공자에게 누수 균열은 하자이므로 무조건 보수할 것을 요구하는 반면 사용자(언론 포함)가 문제를 제기할 때(공공공사의 경우) 발주자는 이에 대해 크게 문제되지 않는다고 답변하는 경우도 많다. 어떤 기술자는 콘크리트의 누수 균열은 피할 수 없는 사항이므로 근본적으로 해결할 수 없으므로 완벽한 시공 및 보수는 어렵고, 다만 전체적인 누수량이 어느 정도 이하가 되도록만 관리할 뿐이라고 말하고, 또한 지하 구조물의 누수 균열은 피할 수 없어, 누수를 시각적으로 가리기 위한 보호벽을 쌓아 관리하는 것이 당연하다고 말하는 기술자도 있다. 그럼에도 불구하고 일반 사용자들은 무조건 누수균열이 없어야 한다고 의견을 제시하고 있다. 특히 언론에 구조물 누수의 문제가 수시로 보도되어 관계자 및 관련 건설기술자들의 자존심이 크게 훼손되고, 이를 보수하기 위한 비용이 엄청나게 지출되고 있음을 볼 때 적당히 간과해서는 안될 문제임에는 틀림없다.(중략)

Despite the trend of decreasing accidents, falling accidents in the construction industry have not decreased and are even rising. Most major accidents are falling accidents caused by hanging scaffolding and are mostly serious. We conducted a review of the literature, institutions, and regulations, which showed that domestic standards are not unified because they are drawn up by referring to overseas standards for hanging scaffolding. New regulations or standards should be established, which should reflect the safety plans for equipment, work advance plans, education, and management. If facility improvement plan for Hanging Scaffolding and implementation of revision of the current work use, regulations and guides are implemented, it will be recognized in advance of the causes of the accident statistics and the classification system and will be the basis for the implementation of joint efforts by workers, managers, supervisors and owners to reduce accidents.

Steel beams are one of primary member and those carries the horizontal load and floor load to axial member. To avoid structural failure when the steel beams are exposed to fire, fire resistance performance requires. Till now, the evaluation for fire resistance of the beam was conducted using the maximum load and standard fire curve defined in the KS F 2257. But recently the constructional patterns are changing toward multi-function performance to get a better structural performance and fire resistance as well. In this paper to get the databases for fire resistance, limiting temperatures of the beam, load-bearing fire tests according to load ratios, two grades of compressive concrete strengths were applied.
