The unnumbered column between 3 and 4 marks the two rows: ST (straight time) on top, OT (overtime) below. Hours, rates and totals for straight time go on the top row and for overtime on the bottom row.
Watch out: On contracts covered by the Contract Work Hours and Safety Standards Act (generally federal contracts over $150,000 under FAR procurement, and other covered or federally assisted contracts over $100,000, per DOL's overtime page; 29 CFR 5.5(b) says in excess of $100,000), hours over 40 in the workweek are overtime at one and one-half times the basic rate, fringe excluded; the FLSA's 40-hour rule can apply where CWHSSA does not, and some states add daily overtime rules on their own public works.
