The purpose of this paper is to find the preconditions of BIM based new design process. As BIM technology improves, investigating new design process will become a greater priority. Our traditional, linear and fragmented design process is not freed from a long-pending questions of poorly coordinated drawings and low production efficiencies. Rather the traditional process is one of the major causes of such issues of low productivity. AIA and NIST proposed new design process to fulfill clients' need for fast and precise delivery recently. The common goal of these two should be better, faster and more precise project delivery created by integration. And we need to create collaborative concurrent design process to optimize the design efforts, But our local AE industry's circumstances are quite different with foreign countries. Therefore, integrated project system cannot be adopted as it stands in foreign countries. This paper will investigate preconditions to expedite the progress of BIM based design process in Korea.
장벌기(長伐期) 시업계획에 관한 연구(Ⅱ) : L . P . 모델에 의한 장기계획
최종천 한국임학회 1989 한국산림과학회지 Vol.78 No.1
본 연구는 장벌기 사업기술을 확립하기 위해 前報와 광의법정림에 기초하여 장기계획을 수립하였다. 이 계획에서는 광의법정상태를 목표영급배치로 하여 목적함수를 10분기간 총 노동량을 최소로 하는 선형계획법이 이용되고 있다. 계획 1, 2, 3의 분기 평균을 법정상태와 비교해보면, 주벌면적은 -9.8% -10.5%, -3.7%, 주벌수학량은 -6.8%, -10.5%, -3.7%, 그리고 총 수확량은 -5.9%, -8.0%, -3.3%로서 큰 차이를 보여주고 있지 않다. 그러나 육림노동을 보면 -28%, -10.9%, -1.8%로서 계획 1은 2, 3과 비교해서 큰 차이를 보이고 있다. 이것은 千葉演習林의 현재 영급배치가 장벌기 시업연구에 적합한 80년생 전후의 임분이 많이 분포되어 있는 탓으로 해석된다.

The main purpose of this paper is to find the phase-in of BIM adoption by focusing on the level of integration. BIM should be aimed at integration and collaboration of all parties furnishing design and construction services to increase the productivity. Therefore, the degree and depth of integration for project collaboration is very important to BIM design process. One of the key advantages of full integration is that is to facilitates the development of detailed information much earlier in the entire design process to improve collaboration among stakeholders. Such integrated use is the ultimate method, but even so, it's not the precondition of BIM. One of the key advantages of relatively low integration as a transition phase is to adopt the BIM earlier than full integration. Such transitional and non-integrated BIM can also reduce the possibility of trial and error in BIM adoption. Therefore, this paper focused on non-integrated use of BIM as a substitute of full IPD by analyzing obstacles in BIM adoption.
