Design VE system in order to promote the economical efficiency and the functional elevation of construction facilities apply to conatruction over 10 billion from december 2005. But it don't achieve purpose of VE original to maximization of value creation through VE because VE perform formal and result center. This study suggests some idea and analyse implementation of design VE through design VE case of turnkey and alternative project performed in domestic.

최근 계획되고 있는 초고층 건축물은 높이에 따른 기술경쟁력의 과시와 함께 비정형의 자유로운 건축적 형상을 통한 디자인 형태의 상징성을 강조하는 경향을 보이고 있다. 이러한 비정형 건축물의 구조시스템은 기술적, 경제적 문제로 인해 한정된 수의 가능성 있는 대안만이 고려되어 왔으나, 첨단 디지털 기술의 발전에 따라 비정형 건축물의 구조시스템에 대해 이전에는 적용이 불가능하였던 다수의 구조시스템 대안을 생성하고 동일한 컨셉을 가진 다양한 구조시스템 대안의 비교평가를 통해 검토안의 수를 최소화하는 것이 가능해졌다. 본 연구에서는 비정형 건축물 구조시스템 설계를 위한 디지털 요소기술에 대해 현재까지의 연구현황을 분석하고 앞으로의 연구방향과 과제를 제시하고자 한다.

In Korea construction project case, architectural construction project is curtailed production because information network process within multidisciplinary isn't smooth. Particularly, the construction is not insufficient about performance, cost and material, construction process, etc. in result various question arises because of design error in construction step. And various mistake is made because communication path within multidisciplinary isn't smooth in architectural design and design change process. Therefore The final object of this study is to propose the establishment method of decision support model for the cooperative design in order to provides improved design coordination and optimize the building system.

Spatial decision support systems(SDffi), a new class of decision support system(DSS), result from the melding together of GIS and DSS, Planning support systems(PS5) add more advanced spatial analysis functions than GIS and intertemporal functions to the functions of SDSS. This paper reports the development of a planning support system providing a framework that facilitates urban planners and civil engineers in conducting coherent deliberations about the generation of satisficing sewers. 1he planning support system for the generation of satisficing sewers(PS5/GSS) was designed from the understanding that land use and development drive the demand for storm and sanitary sewers. Through four stages of supply, demand, alternative generation, and evaluation, PSS/GSS integrates basic planning, preliminary design, and engineering design of sewer. GIS and graphic user interface are excellent toolboxes for designing sewer networks, estimating the quantity of wastewater, and showing generated alternative sewers. A sewer model using simulation tedmique can generate an initial sewer. Users can define alternative sewers by the direct manipulation of sewer networks or by the manipulation of parameters in the sewer model. The sewer model evaluates the performance of the user defined alternatives.

Construction project consists of several stages such as planning, design, construction, operation/maintain, etc. Decisions made in the planning and design stage have a significant impact on the construction and operation/maintain stages. Identifying key resources contributing to duration and cost of design alternatives is an important measure to achieve effective coordination between design and construction. This study proposes a method which finds an optimal design alternative by taking into account of resource planning, expected duration, and cost in construction stage. Base on literature review relative to the assessment of design alternatives, a method which predicts required resources, duration, and cost of the design alternative is established. Then, a method that identifies an optimal design alternative based on the preference of a certain project criteria is developed. Finally, a case study is presented.

합리적인 교량 대안선정을 위해서는 설계 시 경제성, 경관성, 안전성 및 기능성, 유지관리 용이성, 시공성 등 다양한 속성을 고려하여야 한다. 이 중 경제성은 초기비용뿐만 아니라 공용수명에 걸쳐 발생하는 유지관리비용, 보수 보강비용, 해체 폐기비용 등의 합인 총 생애주기비용에 대해 최소의 비용으로 최상의 가치를 창출하도록 하여야 한다. 본 연구에서는 건설계획과정에서 대표적으로 고려될 수 있는 대안으로 세 가지 교량 형식(강상자형교, 소수주형교, PSC-I형 거더교)을 대상구조물로 선정하고 교량의 공용수명은 상태등급곡선으로부터 추정한 내하율 곡선을 사용하여 산정하였다. LCC최적설계를 위해 설계변수, 제약조건, 목적함수를 구성하였고, 총 생애주기비용을 공용수명으로 나눈 연간생애주기비용을 사용하여 하여 합리적인 교량의 경제성 분석을 수행하였다.

This research attempts to develop 4D CAD function to support optimal road design by expanding the existing 4D CAD utilization system, which focused on construction phase, to the design phase. The functions such as earthwork simulation for selecting of road alignment, alternative route simulation and structure type simulation were suggested as functions to support road design. Through those virtual reality (VR) functions, visual confirmation of the condition of route and earthwork Is possible by the developed system, and an optimal alternative route can be selected by carrying out layout simulation of the alternative route. The functions presented in this research provide the decision making tools based virtual model for efficient support to road design.

본 고에서는 지식베이스엔지니어링이 기존의 제품개발 방법론을 개선하기 위한 지능적인 설계도구로서 컴퓨터를 사용하는 새롭고 흥미로운 대안임을 살펴보았다. 전문가의 설계 및 현장 경험을 조직적이고 체계적으로 수집하여 활용하는 것은 동시공학(Concurrent Engineering) 방법론의 실행을 위한 도구로서 매우 중요함을 살펴보았다. 또한 시스템의 효과적인 구축을 위해 어떤한 것들을 고려해야 하는지도 살펴보았다. 이러한 일련의 과정을 통해 설계 분야가 미약한 국내 환경에 지식베이스엔지니어링이 하루 속히 정착되기를 희망한다.

From 2010 years to 2013, the selection method of successful bidder has been changed design suitable lowest method, comprehensive evaluation method(bid price adjustment, design score adjustments, weight standards), fixed amount best design method. Therefore this study was presented by analyzing the impact on the domestic construction industry according the way to determine the successful bidder, the evaluation order method and the operational issues through the analysis of order status, order number, results of acceptance an order, success rate range, results of acceptance an order according to weight success rate, results of acceptance an order by work type and order institution of a turnkey alternative tendering construction performed in domestic civil part.
