Check the governing design, bar counts and sizes, spacing and group extents, connection reinforcement, embeds, openings and the response to earlier comments. Record the design and placing references together so the engineer and detailer can resolve the same question.
Establish the governing design issue
Collect the structural design drawings, general notes, reinforcement legends and approved design changes cited by the placing package. Identify missing referenced details before assessing the affected reinforcement. A superseded drawing can create an apparent conflict or conceal a real one.
Review the same condition in both sets. Slab thickness, support position, bar direction, layer and extent determine which design note applies. A similar-looking detail elsewhere is not evidence that the same reinforcement governs this location.
Ten checks from design to placing
| Check | Sources to compare | Question |
|---|---|---|
| Design issue | Structural drawings, revision record, approved changes | Is the complete governing design available for every cited placing detail? |
| Member and location | Structural plan, placing plan, sections | Are both documents describing the same slab, strip, wall or support? |
| Bar count | Design legend and detail, placing callouts | Do the required counts appear in the corresponding direction and layer? |
| Bar size | Design reinforcement notes, placing callouts | Does the bar size agree for the base mat and each separate additional group? |
| Extent and spacing | Design plans and sections, bar-group limits | Are spacing and limits assigned to the intended zone and supports? |
| Connections | Design connection details, placing plan | Can dowels, couplers and cast-in connection sets be located and matched? |
| Local reinforcement | Embed and opening details, placing package | Are local bars traced to a placing callout or an identified separate package? |
| Curtain-wall anchors | Anchor layout, structural details, placing plan | Are local anchor bars coordinated with the confirmed mullion positions? |
| Cover and geometry | Design sections, placing sections, resolved comments | Do the documented cover and layer positions agree for this condition? |
| Comment closure | Review comments, revised placing sheets, design responses | Does the new issue address each comment and identify the supporting design decision? |
Use the CSV to record the actual sheet and detail references, decision, reviewer and closure evidence. These prompts are document comparisons, not default reinforcement design values.
Keep base mats and added reinforcement separate
Follow the design’s base reinforcement separately from additional support, edge, opening or step reinforcement. A placing note showing additional bars does not establish that the base mat is present. Conversely, a base-mat note does not establish the local bars required by another detail.
Compare a quantity only after identifying its direction, layer and zone. Record a bar-size mismatch separately from a spacing or length mismatch so the responsible designer can answer precisely. Preserve any accepted change rather than replacing it with an assumed typical condition.
Trace embeds, anchors and future openings
Locate the reinforcement required around an embed or anchor in the actual placing plan. Check whether it is included in this package or in a named separate package. For curtain-wall anchors, coordinate the reinforcement with the confirmed mullion layout; a generic detail alone does not establish placement.
Future infill connections also need coordinated locations. Follow the bars and matching cast-in connections around the opening, using the governing connection detail. Record missing information before releasing a placing assumption to the team.
A published reinforcing review example
In the concrete deck reinforcing review, placing plans showed fewer top bars than the supplied structural design and smaller base-mat bars in another location. Other comments requested a missing governing revision and traceable reinforcement at embeds, curtain-wall anchors and future infill connections.
Those comments show why a comparison needs the complete design and all relevant placing packages. They remain review questions for the engineer and detailer; the case study does not establish fabrication approval or a completed correction.
