1. What should designers consider when choosing girder flange sizes?
2. Is there a minimum plate size to use for webs and flanges?
3. If welds are required for bearing stiffener to flange in design, how can this be done most economically?
4. How should crossframes be detailed for bridges that incorporate skew and/or curvature and have differential deflection between adjacent girders?
5. If configuration and design allow choice, what specific details should be employed in four-sided box girders to address ease of fabrication and economy?
6. What should designers consider in tub girder (open box) cross sectional geometry?
7. Are there preferred details for stiffeners inside a tub girder (open box)?
8. If safety handrails are required for girders, what economical details are available?
9. Is there anything designers can do to help fabricators reduce the cost of blasting and painting steel structures?
10. What requires consideration when addressing bridge member transportation economy?
