More panels per truck load, and smaller cranes Increase floor space outboard of floor plate Less trades on site if panels more completed in plant Light Weight Veneer Panels Hung off of Structure Glass fiber reinforced concrete Light gauge steel stud framing 13mm panel thickness 40mm flange Steel rod anchors 7.27  Tilt up Wall Panel Disadvantages Fabricated on site horizontal position Not as consistent quality as controlled environment Strength Durability Finish Dimension On site formwork Increased panel thickness Scheduling Advantages No Transportation Cost Reduced reinforcing to offset stress of transportation Less Size limitations due to Highway restrictions
