Comparative evaluations of design-build (DB), to design-bid-build (DBB), aredocumented in literature. However, a recent study suggests that even though several studies have been completed to compare DB and DBB, there are few statistically significant comparative results. Comparative analyses of highway projects of the same scope, size, and type could provide the basis to make the argument for the use of either DB or DBB on highway projects. The objective of this research is to compare DB to DBB on highway projects. The basis of comparison includes project cost, contract duration, number and type of contract change orders. Projects used for this research were obtained from the Washington State Department of Transportation (WSDOT). The projects were subsequently selected based on project scope,size, and type, and then analysed using quantitative methods. The research found that there is enough evidence to support the use of DB over DBB on highway projects. The findings of this study have significant implications for practitioners and policymakers on highway projects and should inform decisions on the choice of project delivery method. The main limitation of the research is that the study used only 14 projects due to the difficulty of finding matching projects,and as such the results could not be generalized. However, the findings add to the body of research on criteria for comparing DB to DBB. To enhance understanding of how project scope, size, and type might affect or be affected by project delivery methods,the research recommends the standardization of project types classification for highway projects

The Impact

Purpose This study aims at identifying the main causes of change orders in highway construction projects, determining the factors that affect rework in highway construction projects, examining the relationship between change orders and rework and at developing a predictive model that will determine the impact of change orders on rework in highway construction projects in Palestine. Design/methodology/approach A questionnaire survey was used to identify the main change order causes and rework causes from the perspectives of contractors and consultants. The questionnaire contained 16 causes of change orders and 19 causes of rework which had been identified from the literature reviewed. The study also identifies the impact of change orders on rework based on data comprising 22 highway construction projects implemented in Palestine. Both descriptive and inferential statistics were used in analyzing the data. Findings The study concluded that the five most common causes of change orders can be identified as: change of project scope by owner (additional – enhancement), lack of coordination between construction parties; owner’s financial difficulties, change in materials, and errors and omissions in design. The study has also established that among the various factors that causes rework, non-conformance with specification requirements, scope changes, late design changes, lack of labor experience, lack of labor skills and improper subcontractor selection top the list. Using regression analysis, the results reveal a significant relationship between change orders and rework cost in highway construction projects in Palestine. Practical implications By ranking the various change orders causes and rework causes from the perspectives of consultants and contractors, the study provides a fresh perspective on an old chronic problem in the construction sector. This study has provided evidence on the most significant change orders causes and rework causes in the Palestinian highway construction, as well as the impact of change orders or rework on constructions sites. Finally, although this study is specific to the country of Palestine, its results can be applicable to other developing countries facing similar problems in their public construction sectors. Originality/value The results address the common causes of change orders and reworks in highway construction projects in Palestine. The results also address the relation between change orders and rework cost based on data collected from highway construction projects implemented in the West Bank in Palestine. This study is the first study conducted in the West Bank in Palestine to identify the change orders and reworks causes in highway construction projects.

Risk Categories

Public agencies generally let construction contracts to the lowest responsible, responsive bidder. In following this practice, agencies recognize there are higher risks of cost growth in awarding to either unusually low bids or to certain “claim-conscious” bidders. Despite this awareness, there are few documented studies supporting or quantifying the presence of these perceived competitive procurement risks. This research undertakes that specific task. First, bids and bidders on a sample of Alabama highway projects are grouped into risk categories by information available at the project bid opening—well in advance of any potential contract award— and without considering actual project performance data. Second, the cost growth experiences of these projects are statistically analyzed based upon these risk groupings. The results indicate that cost growth on Alabama highway projects is significantly more likely when projects are awarded to unusually low bids or to certain bidder types. A similar study performed earlier on Texas highway projects provides nearly identical results. This type of analysis and the derived information can be used by public agencies to amend the procurement process and objectively disqualify unusually low bids or questionable bidders without abandoning competitive procurement principles.
