At the right side of the photo a mechanic kneels over a bucket. Loose cold rivets lie nearby, suggesting that this photo was taken early in the morning before the forgeman had set up his fire. it is also possible that the forgeman may have been on a lower level and the mechanic visible here is the riveter's assistant; a fuzzy second figure--the riveter--appears to be clinging to the far side of the column behind the kneeling mechanic. In the foreground, a girder is being placed. The fuzzy figure just to the left of the column (left center of photo) is an ironworker guiding the girder in place. The wind bracing system for the building is visible in the heavy diagonal members, as are the fabricators markings on the gusset plate just to the right of the derrick.
