Abstract
보금자리주택 건설에서 분양가 인하의 하나의 방안으로 직할시공제가 도입되었다. 특정 발주방식을 대규모 공공건설사업에 적용 할 경우 본격적인 적용이전에 해당 발주방식에 대한 각계의 논의를 수렴하고 해당 발주방식이 사업성과에 미치는 영향을 다각도로 분석할 필요가 있다. 이에 본 연구에서는 공공건설사업에의 직할시공제 적용에 따른 공사비, 공사기간, 품질, 리스크 등 사업성과에 미치는 영향을 전문가 면담과 해외사례 조사를 통해 분석하고, 이러한 문제점들을 해결하고 공공건설사업에의 직할시공제의 효율적 적용을 위한 방안을 제시하였다. 먼저 직할시공제하에서는 발주자의 업무가 대폭적으로 증가하므로 해당 공공발주자 조직에서 증가된 업무 수행이 가능한지를 점검해야 하고, 이에 따른 발주자 조직과 업무절차의 변화가 필요하다. 아울러 직할시공제의 효율적 적용을 위해 다중시공기반 CM방식 등 다양한 수행방식을 적용 할 필요가 있으며, 공사관리 절차 및 시스템 구축, 협력업체 강화 등이 필요하다. Multi-trade Contract Method was introduced as a means of cutting down construction cost of public housing for low income people. Before a specific project delivery method is applied to large public construction project, it is necessary to discuss all the issues raised up from all the parties in construction industry and all the issues which can impact project performance. Thus the interviews were conducted with industrial professionals from diverse organizations and previous studies were investigated to figure out how this newly introduced project delivery method may impact owner's role and responsibility and project performance in terms of cost, schedule, quality and risk. Under the Multi-trade Contract Method, project owner's management tasks will be highly increased, so it should be checked out if the owner can do its role and responsibility. Public owner's organization also needs to be changed and proper project management procedure and system need to be established. In addition, for efficient application of Multi-trade Contract Method, public owner should consider diverse management approach to deliver the project, and how to select and maintain qualified specialty trades.
