A steel column is centered within a formed concrete pad, featuring a control or construction joint with a two-inch typical clearance, number four centering trim reinforcing bars, and infill concrete specified to be cast after the column base plate is grouted. A plan view of a Grade 50 steel base plate measuring three feet square is anchored by two-and-one-quarter-inch diameter A354 Grade BD tension anchors with three-quarter-inch by five-inch by five-inch plate washers at each anchor location. Complete joint penetration welds are indicated on the connection elements. Dimensions establish the column centerline spacing and anchor bolt layout.
