At the current time, most agencies do not have a set of straightforward guidelines by which they decide whether to adopt PPP for a given project, and if to adopt one, which type of PPP should be adopted. This thesis develops a PPP evaluation and decision support framework that Roadway Agencies can use to decide whether to adopt a PPP for a given project, and if affirmative, what type of PPP to adopt, such that there is maximum financial benefit to the Agency. To that end, the following six typical PPP types are explored: (i) performance-based contracting; (ii) cost-plus-time contracting; (iii) incentives/ disincentives; (iv) design-build and their derivatives; (v) warranties; and (vi) lane-rentals. The decision-support methodology is based on an elaborative evaluation – through advanced statistical modeling – of the aforementioned PPP types by procurement package, in terms of cost savings, cost overruns, time delays, change orders, and safety and operations before, during, and after construction and preservation work. Using pairwise comparison and analytical hierarchical process, the “optimal” decision is one that is associated with the highest possible effectiveness and the least possible cost to the agency, |
