Abstract

Project bundling has been introduced as an innovative approach that groups several infrastructure projects into a single contract. Project bundling has numerous benefits such as expediting project delivery, capitalizing on economies of scale, and reducing the overall contract cost. However, agencies implementing project bundling also face some challenges, one of which is assessing the feasibility of a certain project delivery method (PDM) of interest. While different PDMs could be used for bundled projects, design-build (DB) has attracted particular interest from project owners as an alternative, innovative PDM due to its numerous benefits related to project performance. While previous research efforts examined different aspects of project bundling in terms of its decision-making factors, opportunities, and challenges, no previous research effort was devoted to studying the feasibility or applicability of the DB delivery method for bundled projects. To that extent, and to fill this gap, this paper develops a scoring framework that assesses the feasibility of the DB delivery for bundled projects. First, a questionnaire survey was distributed to industry experts to quantify the importance of 25 project bundling objectives. Second, principal component analysis (PCA) was implemented to calculate a weight for each project bundling objective. Third, a score for each project bundling objective was calculated and the DB feasibility tiers were identified using a series of statistical tests. Finally, a user-friendly feasibility scoring framework was developed to assign a feasibility score for the DB delivery method based on the user's inputs related to the bundled project of interest. The results showed that the key project bundling objectives that mostly increase the feasibility score of the DB delivery method for bundled projects are (1) Having specific scheduling, sequencing, staging, and phasing; (2) Meeting tight milestones or deadlines (timely completion of individual phases); and (3) Completing the overall project on schedule. Ultimately, this research adds to the body of knowledge by equipping agencies and project owners with a decision-support system that helps them make the go/no-go decision for the DB delivery method for their bundled projects. By making the right PDM decision, project owners can enhance their bundling practices (especially in relation to the PDM selection), reduce the associated risks and challenges, improve the overall schedule of the bundled program, and keep the cost within the identified budgets.
