Practical Steel Deck Design Review Checklist for Engineers
A structured, code-aligned review workflow for structural engineers and steel-deck detailers performing design reviews on commercial and industrial projects. This checklist addresses the critical control points that separate compliant, constructible submittals from costly field corrections.
Why a Structured
Review Checklist Matters
Steel deck submittals influence nearly every downstream trade. A disciplined review process ensures that critical design, capacity, attachment, and coordination requirements are verified before fabrication and installation begin.
The Cost Of Missed Details
Small Error
Incorrect gauge, attachment requirements, bearing dimensions, or missing notes.
Large Consequence
RFIs, rework, change orders, schedule delays, and coordination conflicts across trades.
Downstream Effects Of Poor Review
Early Detection Delivers Exponential Value
Industry data consistently shows that errors identified during submittal review cost significantly less to resolve than identical issues discovered during construction or after installation. A disciplined checklist remains the most effective preventive tool available.
Scope Of This Checklist
This presentation walks through the five primary review domains engineers should interrogate on every steel deck submittal. Each domain includes critical verification requirements, governing references, and common red-flag conditions that may require revision or rejection.

Great Projects Begin
With Great Reviews
The objective of a steel deck submittal review is not merely compliance checking. It is proactive risk reduction. By systematically reviewing key structural, material, diaphragm, bearing, and coordination requirements, engineers can prevent costly downstream issues and ensure project execution proceeds with confidence.
The first review question is simple: does the submitted product match the product that was designed? Confirm geometry, design thickness, coating, steel properties, and traceability before accepting substitutions.
Confirm profile designation, rib depth, rib width, flute spacing, cover width, embossments, and the exact composite or form-deck configuration against the approved design basis.
Review uncoated design thickness—not nominal gauge alone. SDI standards permit gauge references only when the manufacturer defines the thickness relationship; design calculations use dimensional base-metal thickness. [6][97]
Confirm the specified coating designation and exposure condition. The supplied review criteria identify G60 as common for interior floor deck and G90 as typical for roof deck or more corrosive environments.
Mill certificates should accompany or be clearly cross-referenced to the deck shipment and product documentation.
A submittal is not verifiable if it lists only a nominal gauge or generic profile name.
Approve the tested and documented product—not an approximate label. Profile geometry, design thickness, coating, steel properties, evaluation reports, and traceability must all align with the contract documents and the structural design basis.

The Compliance Principle
Confirm span continuity assumptions (single, two-span, or multi-span) match framing layout. Check unshored construction loads — wet concrete, 20 psf live load, and point loads — against section properties. Verify construction load tables align with pour sequence and shoring plan.
Distinguish composite deck sections (embossed per SDI-C) from non-composite form deck. Confirm published tables account for slab depth, rib geometry, and concrete density. Ensure superimposed loads match structural drawings — mismatched density can shift capacity by 10–15%.
SDI recommends L/240 for live-load deflection and L/180 (or ¾" absolute) for wet-concrete stage. Verify span tables meet both criteria. Flag any relaxation of the ¾" limit without justification, as ponding in long spans can amplify deflections.
Cantilevered deck at slab edges, stair openings, and pour-stops requires explicit verification. Standard span tables do not apply. Any cantilever over 12" must be supported by calculation or approved detail, with focus on negative moment capacity and uplift attachment at back-span support.
Always cross-reference manufacturer load tables with ICC-ESR reports — generic SDI tables may not apply to proprietary profiles.

Steel deck diaphragms are primary lateral-force-resisting elements in many low-to-mid-rise structures. Proper review requires verification of diaphragm capacity, attachment patterns, and boundary conditions to ensure the intended lateral load path is maintained.
Review the diaphragm design to confirm that published SDI-DD (Diaphragm Design Manual, 4th Edition) or ICC-ESR tables are applied correctly. Verify that deck configuration, attachment systems, aspect ratio limits, and published capacities align with the project requirements and structural design assumptions.
Confirm that chord members, collector elements, and drag struts shown on the structural drawings are reflected within the deck shop drawing attachment notes. A diaphragm submittal that is silent regarding chord and collector connections is incomplete and should be returned for revision.
Weld attachment patterns such as 36/7, 36/5, and 36/4 must match the SDI notation shown on the structural drawings. For screw or powder-actuated fastening systems, verify the fastener is listed in the applicable ICC-ESR report and that supporting steel thickness satisfies qualification requirements.
Sidelap fasteners are frequently underspecified on submittals. Verify spacing matches the diaphragm design and high-shear demand regions. Generic references to "standard" sidelap spacing without regard to the diaphragm shear map should be flagged for clarification.
Edge zones often require increased attachment density. Confirm pour-stop angles, closure plates, perimeter beams, and boundary attachments are called out with the correct weld or screw pattern required by the structural edge details.
A disciplined three-step diaphragm review — demand, attachment, and boundary verification — captures the most common non-conformance issues before they reach construction. Consistent review of these areas significantly reduces field conflicts and helps preserve the integrity of the building's lateral-force-resisting system.

A deck submittal is reviewable only when the geometry, bearing, end laps, pour stops, closures, attachments, and supporting documentation all agree with the structural design.
The supplied criteria require a minimum 2-in. end lap with a fastener at each rib. Confirm the lap location, fastener pattern, and support condition on the shop drawings. [105]
A sheet that terminates over a beam or joist with less than the required bearing should not be accepted through an assumed field fix.
Pour stops, closure channels, side closures, and edge angles must be sized and attached for wet-concrete hydrostatic pressure and the actual placement sequence.
ICC-ESR or proprietary load-table reference.
Deck layout keyed to the structural framing plan.
Profile, gauge, span, and load summary.
Attachment zones, collectors, perimeters, and special patterns.
Openings, bearing, end laps, edges, closures, and special conditions.
Material certifications or a compliant certification statement.
EOR stamp where required and detailer review stamp.
List every variance for EOR disposition—never incorporate it silently.
A complete submittal is more than a correct deck profile. It must show how each sheet bears, laps, terminates, closes, attaches, and transfers load—and provide enough documentation for the reviewer to verify those conditions without inference.
