For deciding the owner's budget of the building construction in the predesign stage, the probabilistic methodologies for estimating the cost are often studied, however these parameter-based conceptual estimating methodology has limitation of applying it to the practical business because it hardly can link the design decision-making and the cost estimating and control. Besides if the result of detail estimating after detail design is over the budget, locally and arbitrarily control the level of interior design and fix the design. This research proposed the prototype-based cost estimating model for building interior construction which leads to estimate the interior cost easily linking with design decision-making and supports to evaluate the design alternatives in the schematic design and the design development stage for office buildings. The model divides the building on the design process by Element Breakdown Structure and presents the design alternative by selecting the elements of each room from the database accumulated the historical office buildings' prototypes and estimates the cost. The 2 case studies presented to validate the effectiveness of as the linking tool integrating the design and construction data and applicability to the practical design on the presented prototype-based model.

The procedure of predicting the construction cost and selecting the best alternative is performed based on comparative review of each building case. In the case of office building, it is required continuously until design is complete, since the owner requirements are various and likely to change during the design process compared to a standardized apartment. However, since the comparison work for each alternative in practice uses only the unit construction cost, there is no correlation between the alternative and the final result, and it is difficult to quantitatively determine the effect of the determined design factor on the total construction cost. It is needed that a means to support the generation of design alternatives using similar building cases during the design phase. This paper proposes a BIM-based data replacing process to support creating and comparison of design alternatives of internal finishing for office building. When design alternatives are created through the proposed process, it is possible to compare several similar cases with current project under equivalent design circumstance. Because only some finishing properties are replaced while maintaining the shape information such as the length, height, and base constraint of the object to be replaced.

The purpose of this study is to suggest a improved tact planning and scheduling by reliable Toning of work area in high-rise building construction. To do this, the characteristics of main work including electric & mechanical work were considered through the interview with field work forces. The content of the study is focused mainly on reliable work flow and rhythmical repetition of uniform resource quantity to manage effective tact planning & scheduling. And also the study recommends more implement of tact planning and scheduling to manage human resources successfully in repetitive building construction.

준공후 10여년동안 사용한 천장 및 벽의 마감재에 대한 전면적인 보수를 실시한 부산 시민회관을 대상으로 보수 전후의 음향특성에 대해 비교 검토하였다. 본 연구에서는 특히 전객석에서의 고른 음압분포와 적절한 잔향시간을 얻기 위한 측면에 주안점을 두고 보수설계를 하였으며 보수 작업시 사전에 음향특성을 측정 분석한 후 이를 근거로 용도에 맞는 음향성능을 발휘할 수 있도록 마감재의 선정 및 배치를 하여 건축설계에 반영하였다.

The serious issue of tall building is to ensure the fire resistance of high strength concrete. Therefore, Solving methods are required to control the explosive spalling. The fire resistant finishing method is installed by applying a fire resistant material as a light-weight material to structural steel and concrete surface. This method can reduce the temperature increase of the reinforcement embedded in structural steel and concrete at high temperature due to the installation thickness control. This study is interested in identifying the effectiveness of light-weight fire protection material compounds including the inorganic admixture such as fly ash, meta-kaolin and light-weight aggregate as the fire resistant finishing materials through the analysis of fire resistance and components properties at high temperature. Also, this paper is concerned with change in microstructure and dehydration of the light-weight fire protection materials at high temperatures. The testing methods of fire protection materials in high temperature properties are make use of SEM and XRD. The study results show that the light-weight fire resistant finishing material composed of fly ash, meta-kaolin and light-weight aggregate has the thermal stability of the slight decrease of compressive strength at high temperature. These thermal stability is caused by the ceramic binding capacity induced by alkali activation reaction by the reason of the thermal analysis result not showing the decomposition of calcium hydrate. Developed light-weight fire protection materials showed good stability in high Temperatures. Thus, the results indicate that it is possible to fireproof panels, fire protection of materials.

The ultimate goal of construction is to complete the given work in the most economical and safest way within the required construction period while meeting the quality standards specified in the design drawing. There are a few characteristics of finish work. First, executed in subdivided processes, finish work involves a very diverse and complex structure. Second, there are no criteria for each segmented process with regard to the appropriate time of input. Third, it is not very necessary to set priorities for lead and lag works. This study intends to provide information on the completion of a project in accordance with the required duration by setting priorities in the delay of each detailed process of finish work to minimize delay in finish work. In this study, finish work is divided into wet work and other types of finish work, and the importance of each process is classified based on the given details of each process. In addition, the study employs a survey to analyze delay factors of a designer, a constructor, and a supplier. Using the survey results, the study sets priorities in delay of final work to provide information on the completion of an apartment project within the planned construction period.

우리나라의 교회는 점점 신도수가 늘어나면서 점차 대형화되어가고 있으며 많은 첨단 설비를 갖추고자 하는 교회도 적지 않다. 하지만, 교회설계에 있어서, 대체로 그 형태와 규모만 중요시될 뿐, 그 기능에 적합한 건축물을 짓는데 소홀해 왔던 것이 사실이다. 교회의 예배공간에서 이루어지는 음향적인 매개체는 찬양과 설교인데, 이 두가지의 물리적 특성이 다르기 때문에 교회건축에 있어 실내음향은 어려운 과제라고 할 수 있다. 즉, 성가는 긴 잔향시간과 음의 따뜻함(Warmth)과 친밀감(Intimacy)등이 중시되는 반면, 설교는 소리의 명료도, 요해도(intelligibility) 등이 중시되는 등 그 음향적인 특성이 달라, 각기 다른 음환경을 요구하기 때문에 강당이나 음악당보다 교회음향이 건축적으로 난점이 있다고 하겠다. 본 연구는 최근에 시뮬레이션을 통해 음향설계를 실시한 규모가 각기 다른 예배실의 제원과 음향성능을 조사하고 그 특성을 비교, 분석하여 일반적인 음향성능을 개선하기 위한 방안을 모색하여 교회 음향설계단계에 자료를 제공하고자 한다. 이를 위하여 예배실의 규모에 따라 5개의 교회를 선정하였으며 시뮬레이션을 통해 얻어낸 각 교회의 성가시, 설교시 실내음향인자값(SPL, RT, C80, RASTI)과 마감재료 등을 조사하고, 비교하였다. 대체로 규모가 큰 교회에서 음압레벨이 작게 나타났고, 잔향시간도 실의 체적이 클수록 크게 나타났지만 마감재료와 형태에 따라 차이를 보였다. 또, 대형교회의 음향적 결함을 보완하기 위해서는 건축의 형태, 재료는 물론, 전기음향설비의 보강이 중요하다고 하겠다.
