Abstract

Despite the recognition of the need for productivity information and its importance, the feedback of productivity information is not well-established in the construction industry. Effective use of productivity information is required to improve the reliability of construction planning. However, in many cases, on-site productivity information is hardly management effectively, but rather it relies on the experience and/or intuition of project participants. Based on the literature review and expert interviews, the authors recognized that one of the possible solutions is to develop a systematic approach in dealing with productivity information of the construction job-sites. It is required that the new system should not be burdensome to users, purpose-oriented information management, easy-to follow information structure, real-time information feedback, and productivity-related factor recognition. Based on the preliminary investigations, this study proposed a framework for a novel system that facilitate the effective management of construction productivity information. This system has utilized Sketchup software which has good user accessibility by minimizing additional data input and related workload. The proposed system has been designed to input, process, and output the pertinent information through a four-stage process: preparation, input, processing, and output. The inputted construction information is classified into Task Breakdown Structure (TBS) and Material Breakdown Structure (MBS), which are constructed by referring to the contents of the standard specification of building construction, and converted into productivity information. In addition, the converted information is also graphically visualized on the screen, allowing the users to use the productivity information from the job-site. The productivity information management system proposed in this study has been pilot-tested in terms of practical applicability and information availability in the real construction project. Very positive results have been obtained from the usability and the applicability of the system and benefits are expected from the validity test of the system. If the proposed system is used in the planning stage in the construction, the productivity information and the continuous information is accumulated, the expected effectiveness of this study would be conceivably further enhanced.

국내 건설산업에서 생산성 정보의 필요성과 그 활용에 대한 중요성 인식에도 불구하고, 현장 단위의 공사계획 시 효과적인 피드백을 통한 생산성 정보관리가 미흡한 실정이다. 공사계획의 신뢰성을 향상하기 위해서는 생산성 정보의 효과적인 활용이 요구되지만, 현장에서는 공사계획을 관리자의 경험 및 직관에 의존하고 있다. 생산성 정보가 효과적으로 관리되지 못하는 이유는 생산성 정보의 관리를 위한 추가 인력투입이 어렵다는 점, 기존의 생산성 정보가 새로운 프로젝트에 적용되기 어렵다는 점 등 때문인 것으로 파악되었다. 이러한 문제의 해결방안을 제시하기 위해서 선행연구조사 및 면담조사를 하였고 그 결과 새로운 시스템이 필요하다는 사실을 확인하였다. 새로운 시스템의 요구사항으로는 최소화된 업무, 한정된 정보관리범위, 정보의 분류, 정보의 피드백, 생산성 저하요인의 고려 등이 있다. 본 연구에서는 상기 내용을 바탕으로 생산성 저하요인 및 생산성 정보의 관리가 가능한 시스템의 프레임워크를 제안하였다. 이 시스템은 사용자 접근성이 좋은 SketchUp 소프트웨어를 활용하여 프로그램의 활용에 따른 추가인력의 투입이나 업무량 증가를 최소화할 수 있도록 하였다. 제안한 시스템은 준비단계, 입력단계, 처리단계, 출력단계의 총 네 단계의 과정을 통해서 정보를 입력하여 처리하고 출력하도록 하였다. 입력한 시공정보는 건축공사 표준시방서에 기재된 내용을 참고로 구성한 Task Breakdown Structure (TBS)와 Material Breakdown Structure (MBS)를 통해서 분류되어 생산성 정보로 변환되도록 하고, 변환된 정보를 그래픽으로 화면에 출력하도록 하여 사용자는 이를 활용해 해당 현장에서의 생산성 정보를 활용할 수 있도록 하였다. 본 연구에서 제안한 생산성 정보관리 시스템을 K 사옥 공사현장에 대입하여 현장적용 가능성 및 정보 활용성 측면에서 검증하였고, 사용성 및 적용 가능성에서 매우 긍정적인 결과와 정보 활용에 따른 이득이 있을 것으로 예상되었다. 본 시스템을 활용할 경우 생산성 정보를 활용한 공사계획이 가능할 것이고 추후 정보가 지속해서 누적될 경우, 본 연구의 기대효과는 더욱 높아질 것으로 사료된다.
