Abstract:

As part of the Innovative Bridge Research and Construction Program (IBRCP), this study used the full-scale construction project of the Route 123 Bridge over the Occoquan River in Northern Virginia to identify differences in the installation practices and comprehensive placement costs of epoxy-coated reinforcing steel (ECR) and corrosion-resistant reinforcing steel (CRR), specifically an ASTM A1035 steel. Two bridge decks were constructed separately with a raised median covering the longitudinal joint between them. The southbound and northbound decks were reinforced with ECR and CRR respectively. Internal Virginia Department of Transportation (VDOT) construction records provided construction costs specifically associated with one of the two reinforcement materials. For this project, the cost advantage of ECR at the time of contract award was not preserved after inclusion of unanticipated construction costs directly related to ECR. Specifically, adding the cost of deck sealing operations to the bid cost of ECR produced an in-place cost estimate of $.804/lb compared to $.780/lb for CRR. Inclusion of the indirect costs of the sealing operations, however, more than quadrupled the unit cost of ECR over bid, predominantly because of road user costs to the public. Moreover, it is expected that this structure will experience dramatic traffic growth in the future. CRR was ultimately cost-competitive with ECR in this project when costs of common VDOT practices related to ECR were included, but CRR potentially possesses superior longevity benefits as a sustainable choice for deck reinforcement, especially since significant traffic growth is expected on this new structure.
