One of the main lessons of teamwork for the Hoover Dam was the High Scalers, who were the men who swung on ropes to clear canyon walls, and the engineers. The engineers designed the cooling systems and the dam’s curvature, but they relied on the high scalers to execute incredibly dangerous work with precision. They swung from heights of up to 800 feet on thin 1-inch manila ropes, using jackhammers and dynamite to strip the walls down to virgin rock . This was not merely manual labor; it was a technical execution of engineering specs. The engineers relied on the scalers to be their eyes and hands in places no level or transit could reach. In return, the scalers relied on the engineers’ precise blasting patterns to ensure they didn't trigger a massive rockfall that would sweep their entire team into the Colorado River below. 

The General Construction Superintendent of the Hoover Dam was Frank Crowe. He was known for being on the ground with the workers, being the connection of the labor workers and the engineers, 'Never my belly to a desk' as he would say. His leadership and communication turned a group of 5,000 workers into an efficient team that finished the project two years ahead of schedule. 

He was known for his interpersonal skills, often being able to recall the names of those who worked for him. His "people genius", as it was called, allowed for clear communication.

Not only was he active around his workers, he actively listened to them and fought for them. Darwin Colby, who had been laid off after completing work on bypass valves and the concrete on the spillways, confronted Frank Crowe. Colby made it clear that he wanted to work. So Frank sent a note to the paymaster and Colby was hired again to continue work on the Hoover Dam.
