Abstract: The midterm evaluation of buildoperatetransfer (BOT) projects should be conducted biennially, whereas the midterm evaluation of largescale bridge and tunnel facilities in China is mostly conducted using the subjective evaluation of government regulatory departments, which is arbitrary and can not reflect the problerms existing in project operation. Therefore, in this study, a midterm evaluation model for BOTmode urban tunnels is proposed, considering the Qingchun Road tunnel in Hangzhou as an example. The proposed model is divided into four firstlevel indices: BOT agreement evaluation, BOT enterprise evaluation, tunnel facility operation status evaluation, and government supervision evaluation. Each firstlevel index is further divided into several secondlevel indices. As such, the hierarchical structure of the BOT model is established. The fuzzy comprehensive evaluation method is adopted to grade the Qingchun Road tunnel. Objective and reasonable results have been obtained using the proposed model to evaluate the Qingchun Road tunnel; hence, this study can provide reference and guidance for the evaluation of similar projects.
