About 80% of highway projects are still built using this method. This study collected data on 140 DBB highway projects with total costs exceeding $10 million from five Texas DOTs: Austin, Dallas, Fort Worth, Houston, and San Antonio. The study analyzes cost- and schedule-related data from these projects and compares their performance across these five districts. Statistical test results show that projects completed under the Houston district had higher cost growth than those in Austin, Dallas, and San Antonio. However, the projects completed under the Houston district had significantly lower schedule growth than those completed under the Austin, Dallas, and Fort Worth districts. This study shows that the project owner also plays a key role in highway project performance and that the district management style is key to reducing cost and schedule growth. The study’s main contribution is that DOTs should identify effective working practices used across district offices to control highway project costs and schedules, so these practices can be applied in future projects to improve performance.Keyphrases: construction intensity, design bid build, texas dot, total cost growth, total schedule growth In: Wesley Collins, Anthony Perrenoud and John Posillico (editors).
