Making splices on rebar is most effectively done after placing and spacing the rebar, and once the supports are adequately set. This timing ensures that the splices are done in a controlled manner, allowing for consistent alignment and spacing of the rebar, which is critical for the integrity of the concrete structure.

When the rebar is correctly placed and supported, it allows for a thorough inspection before the concrete is poured. This step is crucial because proper rebar placement enhances the performance of the splice. It ensures that the splices are located in the right position and that they maintain the required tensile strength to effectively transfer loads across the connected bars.

Making splices before placement can lead to misalignments, and doing so after the concrete is poured can complicate adjustments and ensure that the load distribution is not compromised. The timing of splicing has significant safety and structural implications, which is why it’s best done after ensuring that all rebar is in its correct position and support structure is established.
