In 2015, after completing the deck replacement of the suspension spans, the Delaware River Port Authority (DRPA) let their largest painting contract ever - over $57,000,000 to blast and paint the entire suspension span including the complete interior and exterior of the towers, deck support steel in the anchorages, suspension cables and various steel repairs. A construction monitoring contract was also awarded on a qualification-based selection. This article is a case study describing the skills that were required for the construction and engineering team, as well as unadvertised skills such as dealing with the nesting Peregrine falcons and the complexities of traffic control on a high-ADT bridge under containment.

Putting the pieces together / Kevin H. Keith in JOURNAL OF PROTECTIVE COATINGS & LININGS (JPCL), Vol. 36, N° 1 (01/2019)

[article]  inJOURNAL OF PROTECTIVE COATINGS & LININGS (JPCL) > Vol. 36, N° 1 (01/2019) . - p. 46-55 Titre : Putting the pieces together : Integrating steel repairs with bridge painting projects Type de document : texte imprimé Auteurs : Kevin H. Keith, Auteur Année de publication : 2019 Article en page(s) : p. 46-55 Langues : Américain (ame) Catégories : Métaux -- Revêtements protecteurs Ponts -- entretien et réparations Ponts métalliques -- Revêtements protecteurs Index. décimale : 667.9 Revêtements et enduits Résumé : There are a significant number of recommendations for combining steel repairs with bridge painting projects. A key factor to remember is that painting and repairs have to work together as a system. All parties should understand the details of the entire system in order to specify and install them correctly. Many detail decisions have schedule and cost considerations in addition to technical considerations. Thus, active leadership and cooperation from everyone involved is required because it is next to impossible to have a perfect design or a bridge without unforeseen deficiencies. Deliberate planning and communication at every step will help to ensure that steel repairs are done correctly.
