A rebar submittal workflow connects structural design information with the detailed documents required for reinforcement review, fabrication, and installation. The process typically begins with reviewing structural drawings and project specifications, followed by rebar detailing, internal quality control, submission, review, revisions, and approval.
A well-organized rebar submittal process helps contractors, engineers, detailers, fabricators, and installers work from coordinated reinforcement information. Depending on the project requirements, the workflow may include rebar shop drawings, placing drawings, bar bending schedules, bar lists, reinforcement models, and supporting documents. The exact review and approval sequence can vary according to the contract, project specifications, and responsibilities assigned to each party.
What Is a Rebar Submittal?
A rebar submittal is a package of reinforcement drawings and related documents prepared for review before fabrication or installation. It translates the structural design into detailed information that shows how reinforcing steel is arranged, identified, fabricated, and placed.
The package commonly includes rebar shop drawings, placing drawings, bar bending schedules, bar lists, and other project-specific information. These documents allow the project team to review reinforcement details against the structural design, specifications, coordination requirements, and construction conditions before the information moves to fabrication.
What Is the Rebar Submittal Workflow?
The rebar submittal workflow moves reinforcement information through several stages before it reaches fabrication and installation. The exact sequence can vary between projects, but a typical workflow follows this general path:
Structural Drawings → Rebar Detailing → Internal Quality Control → Contractor Review → Engineer/EOR Review → Comments and Revisions → Resubmittal → Approval → Fabrication → Delivery → Installation
Each stage has a specific purpose. Early review and coordination can help identify discrepancies before they affect fabrication, material delivery, or field installation. The sequence is similar to the steel shop drawing approval process, though reinforcement-specific checks differ.
1. Review Structural Drawings and Specifications
The workflow begins with reviewing the latest structural drawings, specifications, schedules, details, addenda, RFIs, and other project information to identify the documents governing reinforcement requirements. This review helps identify design changes, missing information, conflicts, and project-specific requirements while reducing the risk of preparing a rebar shop drawing submittal from outdated documents.
2. Prepare Rebar Shop Drawings
After reviewing the project information, the detailer prepares rebar shop drawings based on the structural design and project requirements. The drawings show bar sizes, spacing, locations, dimensions, marks, bends, laps, and other details needed for fabrication and placement, coordinated across plans, sections, schedules, and details.
3. Prepare Bar Bending Schedules and Bar Lists
Once reinforcement is detailed, bar bending schedules and bar lists are prepared to ensure each bar is clearly identified and traceable to the drawings. Keeping these documents consistent helps prevent review questions and fabrication issues, while any detailing changes should be reflected before submission.
4. Perform Internal Quality Control
Before submission, the drawings and schedules should undergo an internal quality-control review to identify errors, omissions, inconsistencies, and coordination issues. The review checks details such as bar marks, sizes, quantities, spacing, cover, laps, and consistency between shop drawings and bar bending schedules, helping reduce avoidable comments in the rebar submittal workflow.
5. Submit the Rebar Package for Contractor Review
After internal review, the completed package is submitted according to the project’s established procedure. The contractor or designated party may review the documents for coordination, constructability, scope, and compliance before forwarding them to the design professional, with the exact submission route depending on the contract and project requirements.
6. Submit Rebar Shop Drawings for Engineer/EOR Review
The rebar shop drawing approval stage allows the structural engineer or EOR to review reinforcement documentation against the design intent and project requirements. The review may cover layouts, bar sizes, spacing, details, sections, and schedules, with outcomes such as approval, comments, clarification requests, or revise-and-resubmit requirements depending on the project procedure.
7. Review Comments, RFIs, and Revisions
If the reviewing team identifies issues or requests clarification, the detailer addresses the comments and RFIs by revising drawings, schedules, bar marks, dimensions, or other reinforcement information. Clear revision control helps the team distinguish current documents from superseded versions, especially when multiple project areas are being detailed at the same time.
8. Resubmit the Revised Rebar Package
After addressing comments and required changes, the revised package is resubmitted with clear revision identification for another review cycle. The number of cycles varies by project complexity, design changes, and review comments, while coordinated documents and timely responses can help reduce unnecessary resubmissions.
9. Receive Approval and Release for Fabrication
Once the required review is complete and the package receives the applicable approval or release status, the approved information can move to fabrication according to project procedures. Using unapproved or outdated drawings can lead to material waste, rework, schedule delays, and coordination issues, so release requirements should follow the contract and project documentation.
10. Fabrication and Material Preparation
After release, the approved reinforcement information is used for fabrication. Bars are cut, bent, identified, and bundled according to the drawings and schedules, while clear bar marks help connect fabricated reinforcement with the approved documentation and support accurate field installation.
11. Delivery and Installation
The final stages involve delivering reinforcement to the site and placing it according to the approved construction information. Deliveries may follow the construction schedule, while field teams use approved drawings, bar marks, and schedules for installation. Field placement should align with rebar placement tolerances, and any field issue or design change should be addressed through the project’s established communication and revision process.
Who Is Responsible for Each Stage of the Rebar Submittal Process?
A rebar submittal workflow involves several project participants, and each may have different responsibilities depending on the contract and project requirements. Clear responsibilities help prevent gaps in communication and reduce delays during review, revision, fabrication, and installation.
Rebar Detailer
The rebar detailer prepares rebar shop drawings, placing drawings, bar bending schedules, bar lists, and other required documents using current project information. The detailer also coordinates reinforcement details, updates documents for design changes or review comments, and performs internal quality control before submission.
Contractor or General Contractor
The contractor coordinates the submittal process by reviewing the package, checking coordination and constructability, forwarding documents for design review, and tracking comments. The contractor may also coordinate approved information with fabrication, procurement, scheduling, and field installation according to the contract and project delivery method.
Structural Engineer or Engineer of Record
The structural engineer or engineer of record reviews the submitted reinforcement documentation against the structural design and project requirements. The review may identify discrepancies, clarification needs, or changes that need to be addressed before the package can proceed.
Fabricator and Installer
The fabricator uses released reinforcement information to cut, bend, identify, and prepare reinforcing bars. The installer then uses the approved construction information to place reinforcement at the project site.
What Does a Rebar Submittal Include?
A complete rebar submittal should contain the documents required by the project specifications and submittal requirements. The exact package varies by project, but common deliverables include:
- Rebar shop drawings
- Placing drawings
- Bar bending schedules
- Bar lists
- Reinforcement details
- Rebar quantity information
- 3D rebar models when required
- Supporting calculations or documentation when required
- Revision information
How Does Rebar Shop Drawing Review Work?
The rebar submittal review checks whether reinforcement information aligns with the structural design, specifications, and project requirements. Reviewers examine global notes, plans, sections, details, bar schedules, and other documentation to identify discrepancies, missing information, and clarification needs before fabrication.
The review also checks bar sizes, spacing, quantities, marks, bends, laps, and coordination with openings, embeds, sleeves, and other building components. Running clash detection in rebar detailing can help identify conflicts early and reduce changes during fabrication or field installation.
Common Rebar Submittal Review Statuses
The terminology used for rebar drawing approval can differ between projects and submittal systems. Common review outcomes may include approval, approval with comments, revision and resubmission, or rejection.
Approved
The submitted package has received the applicable approval required by the project’s review procedure. The project team can then follow the established process for moving the information toward fabrication or the next construction stage.
Approved With Comments
The documents may be permitted to proceed subject to the comments identified by the reviewer. The project-specific procedure should establish how those comments are incorporated and documented.
Revise and Resubmit
The submitted information requires changes before it can move forward. The detailer or responsible party addresses the comments, updates the affected documents, and submits a revised package.
Rejected
The submitted package does not meet the applicable requirements and requires further correction before approval can be considered. The reasons should be identified so the next submission can address the outstanding issues.
Common Reasons Rebar Submittals Are Returned
A rebar shop drawing submittal can be returned for several reasons. Some issues originate from the detailing process, while others result from incomplete project information, design changes, or coordination problems.
Outdated Structural Drawings
Preparing reinforcement drawings from an outdated structural drawing set can create discrepancies between the submittal and the current design. Before detailing begins, the project team should confirm that the latest applicable drawings, specifications, RFIs, and revisions are being used.
Missing or Incomplete Information
A package may require clarification if required details, schedules, references, or supporting documents are missing. Incomplete information can make it difficult for reviewers to verify the reinforcement and may result in additional review cycles.
Drawing and BBS Mismatches
Differences between shop drawings and bar bending schedules can create confusion during review and fabrication. Bar marks, quantities, dimensions, shapes, and lengths should be checked across the related documents before submission.
Incorrect Bar Sizes or Spacing
Incorrect reinforcement sizes, spacing, locations, or quantities can result in comments or revisions. These details should be checked against the structural drawings and applicable project requirements during internal QC.
Coordination Conflicts
Reinforcement may conflict with openings, embeds, sleeves, structural components, or other building systems. Identifying these conditions during detailing and coordination can help reduce changes during fabrication or installation.
Unresolved Design Questions
When structural information is unclear or conflicting, submitting the drawings without resolving the issue can lead to review delays. The appropriate RFI or clarification process should be used when additional information is needed from the design team.
Inadequate Revision Tracking
Poor revision control can make it difficult to determine which drawings and schedules are current. Clear revision identifiers, document control, and distribution procedures help reduce the risk of outdated information being used for fabrication or installation.
How to Reduce Rebar Submittal Delays?
Reducing delays starts with using current project information and preparing a complete, coordinated package before submission. The detailer should review drawings, specifications, RFIs, revisions, bar schedules, and coordination details while completing internal quality control to identify issues early.
Clear revision tracking and communication also help keep the rebar submittal workflow moving. Review comments, RFIs, and design changes should be addressed promptly, while the project schedule should allow sufficient time for submission, review, revisions, approval, fabrication, and delivery.
Rebar Submittals and the Construction Schedule
A rebar submittal workflow is closely connected to the construction schedule because reinforcement must typically be detailed, reviewed, approved, fabricated, delivered, and placed before concrete work can proceed. Delays at one stage can affect the activities that follow.
For this reason, the rebar submittal process should be planned alongside the construction schedule. Projects may submit reinforcement packages by building area, floor, structural element, or construction phase, allowing approved information to reach fabrication and installation teams when needed.
The submittal schedule should consider the time required for detailing, internal quality control, contractor review, engineer review, revisions, and approval. A typical sequence can be represented as: Detailing → Submittal → Review → Revision → Approval → Fabrication → Delivery → Installation. The exact timing depends on project size, complexity, review procedures, fabrication capacity, and construction requirements.
How Revisions Affect the Rebar Submittal Workflow
Design changes can affect the rebar submittal workflow even after drawings have been submitted or approved. A change in bar size, spacing, geometry, structural element, or reinforcement arrangement may require updates to shop drawings, bar bending schedules, bar lists, and models.
The impact of a revision depends on when it occurs. A change made during detailing may only require drawing updates, while a change after fabrication has started may affect material, production, delivery, and installation. Clear revision management helps the project team identify what changed and which documents need to be updated.
