Concrete Tilt-Up QA:Your Checklist for Flawless Panel Erection

Concrete Tiltwall  Checklist

 

   1. Verify the slab is clean, smooth, and free of defects that could affect the panel face.

    2. Ensure that the bond breaker is applied evenly and completely across the casting surface and allowed to cure per the manufacturer's instructions.

   3.  Ensure the bond breaker is confirmed to be compatible with any slab sealants and panel surface treatments.

   4. Ensure the panel location, dimensions, and openings are square and accurate (± specified tolerance).

    5.  Ensure that the reveal strips and chamfers are properly installed, secured, and straight/plumb.






      6.  Ensure that the rebar size, spacing, lap length, and clearance (cover) are correct per shop drawings.

 

 



 

 

 

 

 





7. Ensure the lifting and bracing inserts are the correct type, size, location, and securely tied to the rebar/formwork.     

 8. Ensure that the conduits, sleeves, and blockouts are correctly located, sized, and secured to prevent displacement during the pour.

 9. Confirm final inspection has been completed and approved by QA/QC personnel and the engineer/foreman.





10. Verify concrete truck ticket matches approved mix design (e.g., strength, slump, air content).

11. Ensure that slump and air content tests are performed and within the specified range before discharge.

 

12. Ensure that test cylinders/beams (for compression and flexural strength) are molded, labeled, and stored correctly.









13. Ensure that the concrete is placed evenly and fully vibrated to eliminate voids without causing segregation




14. Ensure the final panel surface (typically the back) is finished per specification (e.g., float, trowel, broom).

15. Ensure that the curing method (e.g., wet cure, chemical membrane) is applied correctly and maintained.

16. Ensure that the panel number, casting date, and orientation marks are permanently stamped on the panel edge/back.




17. Ensure that the compressive and flexural strength tests meet the minimum required for lifting (typically 2,500 psi).

18. Ensure the lifting anchors, clutches, and rigging gear (spreader bar, slings) are inspected, certified, and compatible with the panel design load.














19. Ensure that the bracing points, brace types, and floor/deadman anchor locations are verified against the engineered plan.

20. Ensure the crane size and capacity is confirmed to handle the heaviest panel at the required reach; outrigger pads/cribbing are secured.

21 Ensure the panel edges are free of overcast (lips) and the perimeter is clear of debris to prevent binding.

22. Ensure the exclusion zones are established and secured to keep non-essential personnel clear of the lifting path.

23. Perform a bearing capacity check by a geotechnical engineer for any crane or concrete pump truck outrigger used on the project.

24. Meet with your crane operator and review a lifting plan before work commences.

Consider all the aspects of the lift:

1) Weight

2) Center of gravity

3) Lifting points on the load

4) The path that the load will travel during the lift.

5) Review the capabilities of the crane; review the load tables, or the instrument of loading.

6) Consider the wind

7) Communication during the whole process of the lift.

8)  Are the outrigger pads a sufficient size?

9) Panel is lifted in the approved erection sequence.


25. Ensure that the leveling shims (or pads) are correctly placed and the panel is set level, plumb, and to the correct height and alignment.

26. Ensure the specified braces are attached at the exact panel and floor locations per the design.



27. Ensure the braces are set at the required angle (typically 50∘ to 60∘ from horizontal) and are secured.

28. Ensure the braces are fully secured with locking pins and the panel is released from the crane only after all temporary supports are installed and checked.

29. Ensure the connections to the slab, footing, and adjacent structural steel are made per design drawings.


30. Ensure the grout beneath the panel is specified strength, applied correctly, and cured before permanent loads are applied.

31. Ensure the temporary braces are NOT removed until the permanent lateral support (roof/floor diaphragm and connections) is complete and approved by the Engineer of Record.



 

 




32. Backfill and compact the pour strip area for

concrete pour.

 33. Drill dowels into the concrete slab. Set with epoxy and check the drawings and specifications for size and placement.
