The construction drawing is a collection of knowledge that has accumulated knowledge and experience of designers and is highly valuable for recycling in the future. BIM is a process and technology that acquires and manages the information needed for the whole life cycle of a building. In order to recycle digitalized 2D drawings in BIM Tool, it is required to use 3D information based on the drawing information to save and reuse them, but there is little research on related methods or system development. In this study, 3D elements are created based on 2D drawing information, and libraries are constructed, and BIM Tool is used to improve the recyclability of drawing information.

As the physical functions of school buildings and the changes in the functions of educational facilities due to social change are increasing, the demand for fundamental and long-term measures for the maintenance of educational facilities is expanding. However, depending on the function of the facility, the maintenance work has been carried out only when it is directly related to the safety problem, or when the request of the school facility manager is requested, rather than supporting preventive maintenance. In this study, we investigate the maintenance process of educational facilities and propose a method to manage the maintenance process of the educational facilities in the unit of space for establishing an efficient maintenance management system.

교육시설 유지관리는 교육환경개선사업의 12개 단위사업별로 취합하고, 심의를 통해 최종 유지보수 대상이 선정된다. 실태조사의 평가점수로 우선순위가 결정되고 순차적으로 예산을 편성하여 진행된다. 우선순위는 유지보수공사 수행을 위한 일정표이자 발주를 위한 중요한 기준이 된다. 예산이 산출되는 실태조사단계와 우선순위 기준의 개별적 유지보수공사는 몇 가지 한계가 있다. 학교시설관리자는 물량산출에 한계가 있으며, 부정확한 소요예산이 도출되는 결과로 이어진다. 우선순위 기준의 유지보수공사는 개별적으로 분리 발주되어 불필요한 공사기간이 반영된다. 학생들은 학습환경에서 불편함이 발생하고, 안전을 침해하는 기간이 늘어난다. 본 연구는 실태조사단계의 BIM 활용과 공종 패키지 플래닝 프레임워크를 제안하였다. BIM은 유지보수 대상의 물량정보를 지원하여 예산산출에 활용되며, 보수이력과 점검결과가 연계하여 평가점수를 도출한다. 공종 패키지 알고리즘은 단위사업별 예산배정 구간을 구분하고, 동일한 공간과 부위에 투입된 공종이 그룹화된 결과를 도출한다. 사례적용 결과 공사기간은 기존 대비 약 37.4% 단축이 가능하였으며, 실무자 면담을 통해 공종 그룹화 대상을 도출 과정에서 활용성이 높은 것으로 평가되었다. The maintenance of educational facilities was assembled in 12 project classifications of the Educational Improvement Program. The priorities were decided by the evaluation scores derived from the condition investigation, and maintenance works were budgeted in the order of priorities. These priorities were a schedule for conducting maintenance and an important criterion for obtaining a construction order. Several restrictions in the condition investigation exist, which derives budgets and conducts maintenance separately based on the priorities. An educational facility manager has a restriction in quantity take-off, which results in an incorrect budget. Discomfort would occur in an educational environment, and a period of infringing safety would increase. This study proposes applying a BIM in the condition investigation and the planning framework for work-type packaging. A BIM supports a budget calculation and derives evaluation scores by linking a repair and an inspection result. The work-type packaging algorithm divides a budget allocation range and derives the result of a grouped work-types applied in an equivalent space and element. As a result of applying cases, it could shorten the duration by approximately 37.4%. Its usability in selecting a grouped work-type was evaluated through an assessment with workers.

The underground passage has a large population compared to other infrastructures and has a long day of use. Therefore, long-term maintenance plans and budget operations are needed to maintain continuous functioning during the period of use. The research center conducted a study of 26 underground stores managed by the Seoul Metropolitan Government. An analysis of the items with regard to the items in the maintenance budget is carried out in relation to items that are unclear from the maintenance budget item, and proposes a calculation method using multiple regression analysis.

As the buildings becomes larger and more complicated, various facility managemet systems have been developed to support increasing maintenance workload. However, the large amount of maintenance information are not being utilized and reused properly. In addition, the information necessary for the maintenance is not transferred from the design/construction to the maintenance. In this study, the authors proposed a program-level smart architectural maintenance framework. A maintenance process model based on the use of BIM was developed and the information occurred at each process was identified. The proposed framework can contribute to promote continuously improving maintenance quality in architectural work by supporting the practitioner"s work through systematic information management.

대학 시설은 다수의 건물들로 구성되어 많은 유지보수항목이 있고 한정된 기간 내에 처리해야 하는 관리상의 제약사항이있다. 대부분의 유지보수 작업은 규모가 작으며 방수공사 등 다수 공종이 동시에 진행되는 특성을 가진다. 시설관리자는 유지보수업체와 연간단가계약을 맺고 공사를 추진하지만 기존 유지보수공사는 일정 및 인력투입계획 없이 공사가 진행되어 공사지연과 다수의 재작업이 발생하고 있다. 본 연구는 시설관리자가 다수의 대학 시설물 유지보수공사들을 프로그램 레벨로 관리할 수 있도록 지원하는 일정계획 모델을 제안하였다. 모델은 순차적으로 진행되는 3단계로 구성된다. 대상 분석단계에서는 수량산출서를 바탕으로 유지보수항목들의 세부공종을 분석하고 수량을 산출한다. 자원 분석단계에서는 효과적인 전문기능공의 투입을 위해 세부공종별 전문기능공 및 공사기간을 도출한다. 일정계획 수립단계에서는 공종별 우선순위와 최적 투입인력이 도출되고 적합도에 따라 일정계획 최적안을 선정한다. 사례적용결과 프로그램 레벨에서 다수 대학시설물 유지보수공사 간의 효과적인 인력투입이 가능하며, 노무비가 감소되어 모델 적용 전 보다 많은 수의 공사를 완료할 수 있었다. 실무자 면담을 통해 모델의 적용성 및 효과성을 평가한 결과 관리자의 유지관리공사 일정관리를 지원할 수 있는 효과적인 도구로 평가되었다. The university facility is made up of multiple buildings and has many maintenance items. In addition, administrative constraints need to be handled within a limited period. Most maintenance work is small scale and multi-work construction, such as waterproofing, needs to be organized. The facility manager makes annual unit price contract with a maintenance company and carries out the maintenance work. On the other hand, delay and rework is occurring because existing maintenance work performed without scheduling based on the manpower input. This study proposed a scheduling model that can support the facility manager to manage maintenance works of multiple university facilities at the program level. The model consists of three stages in order. In object analysis, details of the maintenance items were analyzed and the quantity is calculated based on the quantity takeoff sheet. In resource analysis, the craftsmen and construction period of detailed works are derived for the effective input of craftsmen. In scheduling, the priority of each work and the optimal manpower input are derived. The optimal schedule is selected according to the goodness of fit. The applicability and effectiveness of the prototype was evaluated through a case study and interviews with case participants. The model was found to be an effective tool to support the scheduling of maintenance works for the facility manager.
