Today, as construction industry grows rapidly, technology has advanced throughout the whole industrial world. Architectural design phase has gone digital from the traditional method of drawing which was an important means in the past, and Building Information Modeling(BIM), an emerging new paradigm, changed architectural design process. So this paper studies the difference between a 2D-based and a BIM-based design process which are currently applied to domestic, and proposes a BIM-based integrated design process in order to help establish BIM to domestic efficiently.

Although pilot projects have been actively carried out from 2017 to present to institutionalize CM at Risk, one of the major tasks for innovation in the construction industry, standards and processes related to Design VE, a key tool for determining GMP in the pre-construction phase, have not yet been established. Therefore, through research and operation status related to CM at Risk and Design VE, and survey on project participants' perception, the problem of the existing design VE process was derived, and the design VE process suitable for the CM at Risk project was proposed. The application plan was proposed in three aspects: Schedule, Cycle, and Process, and the appropriateness and applicability were verified through FGI. The results of this study are expected to be used as basic data on the establishment and legislation of order standards to be made in the future.

이번회에는 UIA 2017 Seoul의 Special Session에서 Digital Design and Fabirication섹션에서 Parametric Design이라는 주제로 발표한 내용을 토대로 재구성을 했습니다. 얼마전 한 인터뷰에서 Parametric design에 대하여 설명을 하라는 질문을 받은 적이 있습니다. Parametric tool을 건축설계에 응용한지 벌써 10여년이 흘렀고 저에게는 굉장히 친숙할뿐 아니라 설계와 디자인의 일부라고 생각했던, 그리고 동시에 너무도 많은 내용을 다루며 건축설계의 과정에서 광범위하게 사용되는 parametric design이란 내용을 짧은 시간안에 단 몇 문장으로 배경지식이 없으신 분들에게 설명을 해야 하였기에 조리있게 이야기를 해 드리지 못했던 그다지 유쾌하지 않은 기억이 있습니다. 처음 UIA 관계자로부터 연락을 받았을 때, 지난 10여년동안 경험했던 많은 내용 중 무엇을 말하는게 가장 좋을까 생각을 많이 했습니다. 결국은 몸담았던 회사들에서 참여 했던 화려한 프로젝트들보다는 건축이나 디자인에 종사하지만 parametric design에 대해서 막연한 생각을 가지고 있는 많은 분들이 parametric design이 가지고 있는 가장 근본적인 장점에 대해서 이해할 수 있수 있도록 중요한 개념과 또한 파라메트릭 디자인 프로세스를 적용한 간단한 예에 대해 잠시 살펴봄으로써 파라메트릭 디자인에 대한 이해를 돕고자 하는 바람으로 아래 소개할 프리젠테이션을 준비했습니다.

Digital Project(이하 DP)는 동대문 DDP, 여수엑스포, 한강예술섬등 비정형건축물의 BIM에 주로 활용되는 BIM Tool이다. 기계, 전기, 자동차분야에 널리 사용되는 Catia V5를 기반으로 건축분야에 맞게 건축, 구조, MEP 모듈을 탑재한 것이다. DP에 대한 자세한 소개는 본 회지 7 8월호를 참조하길 바란다. 현재 국내에는 DP가 많이 보급되지 않았고 배우기에도 Revit에 비해 상대적으로 까다롭기 때문에 유저층이 많지 않지만, 해외에서는 유저가 많으며 많은 Add-in이 만들어지고 있다. 이번호에서는 지난호에서 소개했던 Revit과 동일한 모델을 이용해 구조설계프로세스에 따라 구조BIM을 생성하고 활용하는 방법을 소개하도록 하겠다.

Investigation results on shear connections design procedure which is conducted in Korea show that there are many communication problems between structural engineer and detailer, and there are unnecessary work procedures. To solve conventional connection design procedure problems, improved shear connection design procedure is suggested. Most of suggested design procedure is controlled by structure engineer, and the introduction of connections standardization makes computer aided design possible. Standardized connection details are satisfied with structural safety and constructability, and it improves design efficiency. Many problems which are caused by conventional design procedure are fundamentally blocked by using suggested design procedure.

This study identifies the current status of hanok design process and required design information through individual survey and interview with hanok architects and builders to suggest a proposal. Current design system turns out to be a common design process not reflecting hanok's unique mechanism of production. The proposal consists of the alternative design process, 'Initial survey / Site and structural planning / Spatial layout and form / Openings, interior and exterior elements design / Detail design', containing the specialty of hanok's mechanism, and the lists of design information required in its each stage. The proposed design process also emphasizes the significance of consultation in a way of designing coordination, and classifies the specific contents for each consultation moments. The study is expected to contribute for architects including the group who are not specialized in hanok to improve the architectural quality by following the systematic design process. Also the design system provides a framework to organize the vast range of design information being recently developed in the technique-oriented area.

Modular construction is combined with manufacturing production process and conventional construction industry technique. Considering characteristic of modular construction production process, manufacturing facilities require indirect costs for utilities, equipment, and overall maintenance, which can affect modular units pricing. However, current modular construction cost classification is inadvertent to reflect the manufacturing overhead costs, because it is generally added as a percentage to sum of labor, material and equipment as it called in single cost pool used. This process is easy to estimate the total construction cost at the project starting points, but it brings on misunderstanding of project profit estimations by "cross subsidization phenomenon". To prevent this situation, in this research aims to provide modular construction overhead cost handling process at the detailed indirect cost calculation for manufacturing stage using Activity-Based Costing as one of the powerful method for overhead costs estimation and allocation. Using this research results, modular construction cost estimators have more detailed cost information of modular units and prevent to misallocate indirect costs. Also, it can be utilized to aid the understanding of the company's profit structure.

Recently, the design-build delivery system is being generalized in domestic construction project. The design-build system is becoming an increasingly preferable alterative to design-bid-build delivering method. In design-build project, however, a large construction company and design firm make up consortium as a design-build contractor rather than single company performs design and construction work. In this case, usually the construction companies take a leading role but due to their lack of managerial know-how in the design-build system, they could miss the merits of this approach. Therefore, it is necessary to investigated throughly the function and information flows all over the design-build project. In this research suggests a process model and database in the whole phase of design-build project. This process model and database system will also support to Improve the consistency of functional process and minimize incoherent activities in each phase of design-build project.

In order to satisfy the extraction and use of information such as estimates and processes required in the design and construction stages of BIM, which is an expectation of overall construction operation for the design and construction stage of domestic buildings, it is insufficient to supply and apply mobile technologies or terminals. In this paper, standardization of BIM-based processes from the design stage to the construction stage is proposed as an efficient construction system method through mobile-based simulation and test-bed case analysis review. The current status and potential of BIM application were identified through theoretical review of BIM and case studies at home and abroad. In addition, the overall flow of the project and the direction of effective process construction were investigated through each process by 3D, 4D, and 5D execution stage and the role of each collaborator. 4D building process BIM simulation system using mobile was implemented by applying a visualization engine that simulates process information, object information connection module, and related object information. Therefore, it was possible to minimize the possibility of re-construction of the BIM design and construction process model through the visualization of 2D drawings based on the 3D model of the building and the review of errors and interferences in the drawings. In addition, in the implementation of simulation for each process of the construction process through mobile devices, it was possible to support construction progress and process management according to the optimal option selected by the user.
