Cortez Bridge PD&E Study


Cortez Bridge, which is approximately 50 years old, was under evaluation for remaining service life. A concrete materials evaluation was required to determine whether the structure would receive repairs and functional upgrades or be replaced. A comprehensive plan for testing and material sampling was developed and multiple parties were selected to perform the work.

CTLGroup began the project as a pile evaluation specialist. During the completion of the pile evaluation, it became apparent that coordinating multiple contractors was logistically difficult and expensive. CTLGroup was able to provide a comprehensive and cost effective solution to perform all observations, nondestructive testing, material sampling, and data analysis to support the evaluation team.

CTLGroup located and opened grouted PT ducts, removed grout samples, observed strand conditions, and performed corrosion testing along the length of the duct and perform repairs; performed nondestructive testing, material sampling and repairs on piles, beams, deck, bents and abutments to evaluate overall concrete conditions; and worked with other firms to optimize the test program effectiveness and to incorporate our findings into a final work product.
