Because irregular shaped buildings are designed with various three-dimensional curves, the difficulty of design and construction is very high, and more construction drawings are needed to reduce construction errors. General 2D drawings may have limitations in conveying the information necessary for construction. By utilizing BIM, it is possible to three-dimensionally design parts that are not expressed on 2D drawings and additional structurall components required for the construction of the curved exterior finishing materials. This study examines the necessity of BIM at the construction stage, its performance through it, and how it can be linked to smart construction technology through construction BIM being applied to the new construction site of Sejong-Pocheon Line Cheoin Rest Area.

저번 회에서는 Barclays Center의 그린루프의 디자인 과정을 개략적으로 살펴보았습니다. 소음 저감의 목적으로 인하여 도출되었던 두 가지의 변수(새로운 루프의 중량과 두 겹의 루프사이에 위치하는 빈 공간)및 기존의 바클레이 센터가 가지고 있는 물리적인 특성(파라펫 및 기존 루프의 형상)을 고려하여 design surface를 설정하였고, 중량에 대한 조건 및 주변의 고층 주거빌딩들로 인해 일반적인 루프와는 다른 미적인 특이성을 고려하여 그린 루프라는 큰 방향을 제시하고, 양방향 곡면의 특성을 가지는 루프의 지오메트리와 시공 상의 복잡함과 공기의 단축을 위해 모듈로 이루어진 시스템을 제안하게 되었습니다. 이번 회에서는 루프의 디자인을 진행함에 있어서 어떠한 제약 조건이 있었으며 그러한 제약 조건들이 최종적인 루프 디자인 및 패턴에 어떠한 영향을 미쳤는지, 그리고 이러한 과정에서 파라메트릭 툴이 어떻게 사용되었는지에 대해 자세히 살펴보도록 하겠습니다. 이어서 다음 회에서는 디자인 측면에서가 아닌 pre-construction의 측면에서 시공상의 시행착오를 줄이고 공기를 단축하기 위한 목적으로 파라메트릭 툴의 사용하여 시뮬레이션을 했던 과정에 대해 자세히 알아보도록 하겠습니다.

Domestic architect office from a period of high growth from the 1970s to the '80s has been established as some of the large corporations or publicly traded corporation. 1997 IMF has pointed out there is a lot of need for improvement activities in accordance with the construction recession since the 2008 global financial crisis. In order to address these causes, the company's continuous efficient operation for accurate efficiency and competitiveness analysis was required. Leverage financial ratio indicators Study Using Data Envelopment Analysis Data Envelopment Analysis (DEA) model, how to find a benchmark for the improvement of the efficiency of inefficient enterprises in various sectors being. In this study, a comparison of the conventional DEA model and the DEA-AR model is used to analyze the efficiency and domestic architect office is to improve the management efficiency.

Waste foundry sand of industrial waste which is happening by vast quantity according to fast development of industry has much the occurrence amount and processing method is depended on reclamation, and is using by fine aggregate for construction by recycling method among others. In this research Waste foundry sand powder into cement replace fare use possibility availability judge wish to Slump and air content decreased the replacement ratio increases by concrete special quality that do not harden according to experiment result, and unit capacity mass and bleeding increased the replacement ratio increases. Hardening concrete intensity special quality displayed strength improvement to replacement ratio 20%, and tendency that watertightness increases most in replacement ratio loft in watertight property appear. Considering the strength and watertight properties, the adequate usage of waste foundry sand powder is the 10% of replacement ratio.

최근 건설 프로젝트의 대형화 및 다양한 신공법들의 도입으로 불확실한 위험도 요인들이 점점 증가함으로써 일련의 시스템적 절차에 따른 리스크 관리(Risk Management) 체계를 수립하여 활용하고 있다. 하지만 국내 시공사와 발주사들은 과거 자신의 경험과 직관에 의존하여 리스크를 다루고 있을 뿐 공사와 관련된 요인을 체계적으로 분류하고 수치화하여 관리하는 곳은 거의 찾아 볼 수가 없는 실정이다. 따라서 본 논문에서는 건설 리스크 관리수준 향상을 위해 건설실패지수를 활용한 기업단위의 정량화 시스템을 설계하고, 이를 표준화하기 위한 정부 연계 시스템 구성에 대해 연구하였다.

Inter-floor noise in an apartment building is a serious problem that causes conflicts between tenants. Accordingly, there are various attempts to solve this problem, but it is not easy to find a clear solution. Therefore, in this study, a soundproofing material between floors was developed that can improve the sagging that occurs after construction. And as a result of testing the developed interlayer soundproofing material, both light weight and weight were grade 1. And it was analyzed that maintenance performance could be improved with integrated structural characteristics.

In order to maintain the existence of a university in the era of infinite competition, it is actively promoting the establishment of a school dormitory, one of the welfare facilities, as a way to attract students who want to enter the university. In the past, university dormitories were built by the university and managed and operated on themselves, but recently, due to the poor financial situation of the university, university dormitories promoted BTL method that private construction company built dormitories and rented them for a certain period of time to manage and operate. J University has dormitories managed and operated by itself and dormitories managed and operated by entrusting the private sector. User satisfaction surveys are conducted on two dormitory facilities with different management and operation organizations, and the contents of the survey are compared and analyzed. This study is expected to be used as basic data when planning a dormitory remodeling project or a new dormitory establishment project in the future.

KPI, an indicator that measures the performance of factors that contribute to achieving strategies of individuals or organizations, is used a lot to analyze the performance of construction work. Construction work consists of individual construction types with different characteristics such as progress method, scale, and input resources, but currently, KPIs for performance analysis of individual construction types are lacking. Therefore, this study aims to obtain and analyze data for establishing construction performance analysis KPIs during construction work to prepare the basis for the creation of future construction KPIs. Preliminary KPIs for earthwork performance analysis selected through this study are expected to be the basis for deriving preliminary KPIs for other individual construction types.

Earthwork is the starting work of construction process, which has the greatest impact on the productivity of the construction project among the works. However, it is difficult to derive accurate productivity becuase the earthwork plan is affected by geological condition of the jobsite. Therefore, a simulation model for productivity analysis of earthwork was developed using CYCLONE modeling method in this study. In this paper, simulation model was made considering the impact factors of earthwork productivity. The proposed model can be utilized for sensitivity analysis in future studies.
