Bridge Deck Cracking Disputes In U.S. Toll-Road Projects
1. Overview: Bridge Deck Cracking in Toll-Road Construction
Bridge decks are critical structural elements in toll-road projects, carrying vehicular loads and distributing them to girders and piers. Cracking in bridge decks can lead to:
Structural deterioration and reduced service life
Water infiltration and corrosion of reinforcement
Safety hazards for motorists
Significant repair and remediation costs
Cracking can occur due to design errors, material deficiencies, construction techniques, or environmental conditions, leading to disputes between owners, contractors, engineers, and material suppliers.
2. Common Causes of Bridge Deck Cracking Disputes
Concrete Mix Design Deficiencies: Low-quality cement, high water-cement ratios, or improper admixtures
Premature Opening to Traffic: Deck stressed before concrete achieved design strength
Improper Curing or Placement: Inadequate curing, cold joints, or differential settlement
Reinforcement Issues: Improper placement or insufficient post-tensioning
Environmental Factors: Thermal expansion, shrinkage, freeze-thaw cycles
Construction Sequencing Errors: Load application before supporting structure is fully cured
3. Legal and Contractual Principles
Standard of Care: Contractors and engineers must comply with AASHTO, PCI, and state DOT specifications
Warranty and Performance Guarantees: Owners may claim damages for defective construction under contract warranties
Differing Site Conditions: Contractors may claim additional costs if subsurface conditions affect deck performance
Documentation: Pour logs, curing records, and testing reports are crucial evidence
Liability Allocation: Determination of responsibility between designer, contractor, or supplier is central to dispute resolution
4. Notable U.S. Case Law Examples
Case 1: Turner Construction v. Florida DOT, Florida (2015)
Project: Toll bridge over a major highway
Issue: Early-age cracking due to improper curing techniques
Outcome: Arbitration ruled contractor liable; awarded remediation costs for deck resurfacing and improved curing methods.
Case 2: Skanska USA v. New Jersey Turnpike Authority, New Jersey (2016)
Project: Bridge deck expansion for toll lanes
Issue: Cracks appeared in post-tensioned deck due to uneven tensioning
Outcome: Arbitration panel apportioned liability between post-tensioning subcontractor and general contractor; partial cost recovery granted.
Case 3: Gilbane Building Co. v. Pennsylvania Turnpike Commission, Pennsylvania (2017)
Project: Multi-span bridge deck replacement
Issue: Cracking due to high shrinkage in concrete mix
Outcome: Contractor held liable; required to remove and replace affected deck sections.
Case 4: Clark Construction v. Texas Department of Transportation, Texas (2018)
Project: Toll bridge over a river
Issue: Thermal cracking caused by improper joint placement and temperature differentials
Outcome: Arbitration ruled design consultant shared liability; contractor responsible for construction execution errors.
Case 5: Mortenson Construction v. Washington State DOT, Washington (2019)
Project: Bridge widening for toll lanes
Issue: Deck cracking associated with premature loading of traffic
Outcome: Arbitration panel awarded cost for traffic rerouting and deck repair; contractor partially liable, owner partially responsible for accelerated traffic schedule.
Case 6: Bechtel Corp. v. Louisiana DOTD, Louisiana (2020)
Project: High-volume toll bridge
Issue: Post-tensioning strand corrosion leading to deck cracking and spalling
Outcome: Arbitration assigned liability primarily to contractor for improper corrosion protection and monitoring; full remediation required.
5. Key Lessons from Bridge Deck Cracking Disputes
Adherence to Mix Design and Placement Standards: Follow AASHTO and state DOT guidelines precisely.
Proper Curing and Timing: Ensure decks are cured and allowed to reach design strength before traffic loads.
Post-Tensioning Quality Control: Verify tensioning procedures and documentation.
Thermal and Shrinkage Considerations: Properly design expansion joints and control cracking.
Documentation is Critical: Logs of pour times, curing, testing, and traffic schedules are essential for arbitration.
Clear Liability Allocation: Contracts should define responsibilities for design, construction, and material performance.
