W-Project is 70-story mixed-use residential building complex project in Busan, the second biggest city in South Korea. As it is a high rise building complex located at the coast, the residents have great ocean view from the height. Though, there were many difficult challenges to be solved to secure structural safety and meet the serviceability requirements. As it is located on the reclaimed land, securing the foundation bearing capacity on soft soil is the first issue to be solved for the stable structure. W-Project. Busan on the way usual track of typhoon, wind load on structure is also critical for structural safety and serviceability for occupants due to wind vibration. This paper will address process of lateral load resisting structural system of W-Project.

Today's construction is more various and more complex. Because of that, a lot of uncertain factors are occurred and they related uncertain construction duration. For management complex architecture project, importance of construction schedule management also increased. In previous studies, one of solutions to overcome those problems is suggested. It was BIM based construction simulation process which focused on construction schedule and construction schedule management. But latest process had limited point which has no duration estimation function. So this paper suggested duration estimation method and developed duration estimation module. Duration estimation module developed with current scheduling tool MS Project and their macro function. However, this module has just developed Reinforced Concrete Structure and has to do more development and research.

Construction period is longer than the non-disclosure in civil construction of apartment house. And this process is intensive at the beginning and end of construction. Because this project management expertise is required. Nevertheless, subsidiary work(Working avoid a tendency of advanced technician, Frequent turnover and employment contracts, etc.) management attention of construction is at a lower level. Because of, there are the bad factors(trial and error, finish degradation, etc.). Therefore, this study analyzed Hindrance Factor of quality control on apartment complex construction work and presented importance of civil construction engineer's role. Also, forms of civil construction engineer, Performance experience and technical Strength of apartment complex construction was investigated for the construction. To this end, It analyzes the relationship between forms of civil construction engineer, Performance experience and technical Strength of apartment complex construction and Construction of evaluation as required by Construction Technology Management Act.

The uncertainty often observed in experimental strengths of masonry constituents makes critical the selection of the appropriate inputs in finite element analysis of complex masonry buildings, as well as requires modelling the building ultimate load as a random variable. On the other hand, the utilization of expensive Monte Carlo simulations to estimate collapse load probability distributions may become computationally impractical when a single analysis of a complex building requires hours of computer calculations. To reduce the computational cost of Monte Carlo simulations, direct computer calculations can be replaced with inexpensive Response Surface (RS) models. This work investigates the use of RS models in Monte Carlo analysis of complex masonry buildings with random input parameters. The accuracy of the estimated RS models, as well as the good estimations of the collapse load cumulative distributions obtained via polynomial RS models, show how the proposed approach could be a useful tool in problems of technical interest.

The contamination(stain phenomenon) of natural marble(sipeol, bianko) of art wall of on-site interior finishing system and wall of elevator hall has occurred. The bottom of the art wall of stone junction tile has defects as cracks. To solve these problems, our research team developed eco-friendly complex stone panel(stone 4T + cement board 6T) and high-frequency hot-melt construction method that can construct in winter.

The complex variable reproducing kernel particle method (CVRKPM) and the FEM are coupled in this paper to analyze the two-dimensional potential problems. The coupled method not only conveniently imposes the essential boundary conditions, but also exploits the advantages of the individual methods while avoiding their disadvantages, resulting in improved computational efficiency. A hybrid approximation function is applied to combine the CVRKPM with the FEM. Formulations of the coupled method are presented in detail. Three numerical examples of the two-dimensional potential problems are presented to demonstrate the effectiveness of the new method.

There are various national standards designed to test the physical properties of waterproofing materials for the respective countries based on each of their environmental parameters, variables and requirements. The problems of these standard systems can be outlined in the following: (1) there are too many test methods and criteria to satisfy in order assess one waterproofing membrane system, and (2) there is currently no known method to compile the separate testing results to provide a comprehensive report on waterproofing system durability. This paper outlines and compares the performance testing results of various types of asphalt waterproofing membrane systems and discusses the potentials of a complex environmental deterioration analysis method.

This study focuses on importance level analysis of environmentally-friendly planning factors using Analytic Hierarchy Process(AMP). This study verify different planning principle makes comparison matrix by a relative comparison value, verified consistency after yield weight to analyze more objective importance for apartment complex estate environmentally-friendly planning factor. In order to decide importance of apartment complex estate environmentally-friendly planning factors multiplying weight of verified planning principle with weight of planning factors. The results are as follows; First, importance of preservation of green tract of lands, Preparation of Biotop, Tree planting of sites, Propriety of development density high except Circulation and practical use of water. Next, valued planning factors constituent appeared to Energy efficient building plan, Rubbish recycling, thermal utilization of solar energy, Artificial tree planting of buildings etc. importantly. Finally, plan constituent that importance is underrated most appeared by Practical use of building materials and equipment, Centralization of energy and resources, Preservation of corridor etc.

Nowadays, the construction of high-rise building is rapidly increasing. There are many cost-increasing factors to the management in the high-rise building construction. For large and complex projects like the high-rise building construction, the more systematic methods and tools are needed for cost control. It is important to identify major cost control items and to manage them for effective cost management in the high-rise building construction. This study proposes a method of identifying major cost-increasing factors in the high-rise building construction based on the Delphi method.

건축물의 유지관리에 대한 중요성이 부각되고 건축물의 수명연장에 대해 많은 관심이 집중되고 있다. 최근 수도권을 중심으로 도심지 등의 주택용지가 부족함에 따라 해결책으로 주상복합건물의 건설이 빠른 속도로 증가하고 있다. 주상복합건물은 부지 내에서 토지이용의 극대화를 가져왔지만, 유지관리단계에서는 관리비용 분담과 관리범위 한계 등으로 인해 상가시설과 주거시설 이해당사자간에 갈등이 발생하는 등 많은 문제점을 내포하고 있다. 본 논문의 목적은 건축물의 초기성능을 유지하고 개선할 수 있도록 설계단계에서 유지관리성능 향상을 위한 체크리스를 제시하는 것이다. 이를 위해 문헌조사 및 설문조사를 실시하여 유지관리의 문제점을 도출하고 설계단계에서의 검토항목을 작성하여 건축계획분야를 중심으로 건축물의 유지관리성능 향상을 위한 가이드라인을 제시하였다. 본 연구결과는 건축물의 생애기간동안 사회적, 물리적, 기능적 변화 요구에 대응하여 유지관리 성능향상에 도움을 줄 것으로 기대된다.
