Putting the Pieces Together: Integrating Steel Repairs with Bridge Painting Projects

Many bridge painting projects include steel repairs as part of the contract. Painting and steel repairs are performed by separate trades and often separate contractors. Even designers may see them as separate activities. However, steel repairs and coatings must work together and be installed as a system to perform as intended. This paper is a discussion about the process of installing steel repairs and painting a bridge at the same time.

Many bridge painting projects include steel repairs as part of the contract. Painting and steel repairs are performed by separate trades and often separate contractors. Even designers may see them as separate activities. However, steel repairs and coatings must work together and be installed as a system to perform as intended. This paper is a discussion about the process of installing steel repairs and painting a bridge at the same time. It includes lessons learned by a resident engineer with experience managing major bridge painting and steel repair contracts. Ironworking operations discussed include some important design requirements, slip critical criteria, scheduling, installation, inspection, and documentation. Paint requirements include specific surface preparation requirements for faying surfaces, slip critical coating requirements, paint compatibility, bolt preparation and coating, scheduling, inspection, and documentation. In addition to advising field personnel, the paper is intended to give constructability guidance to design professionals and facility owners. The goal is to prevent compromised repairs and coatings by integrating the design with the installation.
