Tilt-Up Design Details

Reference documentation for standard tilt-up concrete panel design details. These documents capture industry-standard dimensions, tolerances, and specifications drawn from the Tilt-Up Concrete Association (TCA), Dayton Superior, ACI, and field practice. They support ConstructiVision’s data model and panel book output.

Why This Matters for ConstructiVision

ConstructiVision generates panel books and construction documentation for tilt-up concrete buildings. The default values and options that ConstructiVision presents to users must align with real industry practice. These documents define:

• Default values for joint widths, chamfer sizes, and sealant dimensions

• Allowable ranges for project-specific overrides

• Documentation conventions that match what engineers and field crews expect to see

• Standards citations for quality assurance and liability protection

All dimensions given as “typical” or “default” should match TCA and ACI published guidance. Project-specific deviations require engineering review.
