Abstract
The Ministry of Land, Infrastructure, Transport and Tourism (MLIT) has adopted the quality-and cost-based selection (QCBS) method in bidding of its public works since 1998. In fiscal year 2009, approximately 99% of MLIT's works were conducted through the QCBS method.
Since the QCBS method enables the client to contract with both superior cost and quality compared to the traditional cost-based selection, the issue has been how to evaluate the technical capacity of the bidder in individual works.
In this paper, we have first analyzed the contents and the weight of the quality evaluation criteria for each QCBS types among public works contracted out by MLIT, and identified issues for technical proposals. Next, we have proposed improvements such as setting appropria te score differences based on precise indicators, and introducing methods that evaluates the company's construction capability of public works.
