1 Project Delivery Selection

Project Delivery Selection / Colorado DOT

In 2011 CDOT’s Innovative Contracting Advisory Committee (ICAC) began work to develop a structured approach for selecting the best delivery mechanism for a given transportation project. Through a set of workshops ICAC identified different factors that the agency should consider in selecting a delivery approach, including five primary factors (project complexity and innovation, delivery schedule, cost considerations, level of design, and risk assessment) and three secondary factors (staff experience and availability, level of oversight and control, and competition and contractor experience). ICAC then defined a three-stage approach for making the delivery decision. In Stage 1 CDOT identifies project goals, constraints and attributes. In Stage 2 CDOT assesses the primary factors, and in Stage 3 assesses the additional secondary factors. The approach is illustrated in the figure. As of 2018 CDOT has used the approach to assess 25 different projects, resulting in the selection of a mix of projects using DBB, DB and GM-GC.
