Abstract

This paper presents a modeling prototype that optimizes construction processes implementing information communication technology (ICT). Using "IAMB", each and every actual steps of the construction process may be defined visually and explicitly by elaborating ICT to improve productivity and management efficiency. It contributes to identify the features on what parts of construction task are covered by ICT, and the effects of ICT on process performance. After analyzing 10 real project cases, ICT application types are classified into four categories according to ICT type, job functions that ICT applied, and the project phase in which ICT used. As a reuslt, it was confirmed that the positive outcomes on the construction process were beneficial to mostly the general contractors and mainly obtained by automated information processing, external consignment and consistent information use. Negative effects, which were occurred by mainly manual manipulation and duplication of information handling, were accrued to general contractors minimally, but to subcontractors maximally. Expert focus group commends that several important issues should be considered when implementing ICT.

본 연구는 시공 및 관리 프로세스의 생산성 및 효율성 향상을 위해 ICT를 적용한 실제 프로세스 사례들을 "IAMB"모델링 기법으로 명시하여, 시공업무의 어떤 단계를 ICT가 대체하며 ICT 도입 특징 및 ICT 도입이 업무 프로세스에 끼친 결과를 분석하였다. 10가지 실제 사례를 분석한 결과, ICT 도입 특징은 ICT의 종류, ICT에 관계하는 주체, ICT가 적용되는 단계에 따라 4가지 유형으로 분류되었다. 각 유형을 분석한 결과, 업무 프로세스에 끼친 긍정적 효과는 주로 정보처리업무의 자동화, 외부위탁 및 일관성 있는 정보취급이었으며, 그 대상은 대부분 원청업체로 규명되었다. 반대로 부정적 결과는 주로 정보의 입력 및 집계 등에 대한 수작업 및 이중 작업의 발생으로 인한 번거로움이었고, 그 대상은 간헐적으로 원청업자 및 빈번히 하청업자가 분포되었다. 정보처리업무의 외부위탁 등으로 주로 원청업체가 긍정적 효과를 수혜하는 반면, 하청업체는 비용과 번거로움을 편무적으로 부담하는 경향을 나타내었다. 이상과 같은 분석을 바탕으로, 시공업무에 ICT 도입 시, 다음과 같은 내용을 고려해야 할 필요가 있음이 규명되었다. 첫째, ICT 적용 패키지를 명시적으로 정의할 필요성. 둘째, 비용 등에 관해서 ICT 적용 시 주 수혜자인 원청업자가 정당하게 비용을 부담하는 것을 명시하는 것의 필요성. 셋째, ICT의 실행기능을 향상시켜, 실제 편익을 극대화하여 부담을 상쇄할 필요성. 넷째, 업무 프로세스에서 일관성 있는 정보활용의 필요성 등이 제기되었다.
