I am writing this letter to commend and thank the members of Local 627 [Phoenix] who worked on the Cholla Unit 1 horizontal superheat project [Joseph City, Ariz.]. The Boilermakers removed and replaced 384 superheat assemblies and made 1,600 welds in 26 days. We x-rayed 240 welds, with no rejects. They managed to do this with wind delays, crane breakdowns and other obstacles. APS [Arizona Public Service, owner/operator] was very pleased with this outage. The project was completed with an excellent safety record and ahead of schedule.
