Planning and coordinating a tilt-up project should be a team effort involving the architect, engineer, and the contractor. Preconstruction meetings are a good way for all parties involved in a tilt-up project the iron out details before work begins. The following are tips on some topics that should be discussed:

  • When planning panel size, try to avoid using different panel widths. That way, the lifting and rigging arrangement can be kept the same throughout the project.
  • The type of crane needed depends on panel size and weight. Consider, though, that hourly rental charges and operating costs for a larger crane may be higher than for a smaller crane.
  • Panel thickness should be such that the height to thickness ratio is about 50. The thickness should also match standard lumber sizes whenever possible to reduce the need for special formwork.
  • Draw complete panel elevations instead of drawing just a few typical elevations.
  • Embed elevation drawings should show the complete panel elevation and dimensions of each embed plate from panel joints and from the floor line.
  • Wind loads and lifting stresses generally govern the concrete strength required. Usually, 3000-psi concrete is adequate to withstand these stresses, but occasionally 400-psi concrete is needed.
