Hard Rock Harrigan

Tim 'Hard Rock" Harrigan, a construction-crew driller working on the site of the Boulder Dam, is in a constant feud with his crew-boss "Black Jack" Riley, because of Harrigan's dislike of Riley's hard-as-nails management of the men, and also because he and Riley are both courting the lady who bakes the pies at the camp commissary, "Andy" Anderson.
