The parapet studs were designed for the wall pressure, not the parapet pressure the structural notes list.
The delegated exterior cold-formed metal framing shop drawings and calculations for a steel-framed event facility were read against the contract structural drawings, and several walls are designed for a lower pressure, a shorter span or a different support than the drawings show.
Cold-formed metal framing shop drawings
Delegated exterior cold-formed metal framing shop drawings, with stud, header, jamb and connection calculations, for a multi-use event facility, read against the contract structural drawings and their latest addendum.
What the review compared
The review read the framing contractor’s delegated exterior cold-formed metal framing package, with its key plans, wall elevations, framing sections, connection details and stud and connection calculations, against the contract structural drawings and their latest addendum. Its instructions asked it to check the shop drawings against the contract drawings, details and specifications, match the same element, location and revision before comparing values, and cite the design evidence for each finding. Code checking was not enabled; the structural drawings were supplied as the reference.
Where the framing and the structure part ways
The parapet studs were designed for the wall pressures rather than the higher parapet pressures the structural notes list, and separate parapet studs above the top beam have no calculation at all. Several sections design studs between beam elevations the contract framing elevations do not show, fasten studs with fixed clips where the contract details call for vertical slide clips, or detail a lighter track, a thinner clip or wider bridging than the calculations and notes assume. Neither the drawings nor the calculations are sealed.
What to verify next
The delegated engineer should rerun the affected stud and connection calculations for the contract pressures, elevations and supports, revise the sections and clip details to match, and resubmit the package sealed before it is approved. Door weights, cladding attachment and glazing head movement go to their suppliers to confirm. Examples that cite a requirement follow the contract structural drawings the customer uploaded; every example is a question for the engineer of record and the delegated engineer.
9 selected examples from the review
Nine distinct findings, summarized for professional verification.
Parapet studs designed for wall pressure
Parapet stud designs use the wall pressures; the structural notes list higher parapet pressures.
Why it matters: The parapet studs may be undersized for their wind load.
What to check: Redesign them for the listed parapet pressures.
StructuralDoor jamb drawn lighter than calculated
An overhead door jamb section shows a lighter track than its calculation designs.
Why it matters: The jamb as drawn is not the member that was checked.
What to check: Revise the section to the calculated track.
StructuralDrawings and calculations are not sealed
The cover defers certification until approval; no sheet or calculation carries a seal.
Why it matters: The structural notes require sealed delegated framing design.
What to check: Resubmit both sealed by the delegated engineer.
StructuralFixed clips where slide clips are shown
Studs fixed at the slab are also fixed at curved parapet and roof beams.
Why it matters: Beam movement would load studs the contract details let slide.
What to check: Change those connections to vertical slide clips.
StructuralTall wall designed for its lowest beam
One high-wall section uses the lowest top of steel; the contract beam rises along the wall.
Why it matters: Studs at the high end span farther than calculated.
What to check: Recalculate the studs for the highest beam.
StructuralParapet studs above the top beam have no calculation
Several sections show separate parapet studs above the top beam that no report models.
Why it matters: Those studs have no design on record.
What to check: Provide calculations for every parapet stud piece.
StructuralBridging rows wider than the notes allow
The bridging detail and stud reports space rows wider than the structural notes allow.
Why it matters: Stud capacities rely on bracing the contract does not accept.
What to check: Tighten the rows and rerun the stud reports.
StructuralAnchors checked in stronger concrete
A jamb anchor check assumes stronger concrete than the structural notes give for slabs.
Why it matters: At the specified strength the anchor may be overstressed.
What to check: Recheck the anchors at the specified strength.
StructuralAngle thickness note below the calculated basis
Clip details allow a thinner supporting angle than the fastener capacities assume.
Why it matters: On the thinner angle, the typical clip falls short of its load.
What to check: Raise the noted minimum angle thickness.
StructuralReview scope and priorities
The review organized the questions by severity, discipline, and source context so the responsible designers could investigate them.

Check the findings with the responsible discipline designers.
High, Medium, and Low priorities
Selected examples retain their assigned priority.
Coordination and completeness within the set
This review checked the documents against one another. No code check was enabled.
Findings connected to their source context
Groundbook links each finding to the sheets it came from so the responsible designer can confirm or dismiss it.
Potential impacts describe the issue type. They are not verified outcomes from this project.
Follow the information across the complete set
Groundbook reads the documents you upload and reports where they disagree, where a reference does not resolve, and where a required value is absent.

Questions for professional verification
The output supports the responsible designers as they review the source documents and decide what needs to change.
What this result means
- Groundbook surfaced potential issues for professional review.
- Severity helps prioritize which questions to investigate.
- The findings describe coordination and completeness questions in the uploaded set.
- Each finding includes source context for verification.
What it does not mean
- Every potential finding is a confirmed error or violation.
- The project was unsafe, unbuildable, or ultimately noncompliant.
- Groundbook replaced the responsible professionals or authority.
- A correction was made, or any cost or delay was avoided.
About this review
Is this a real review?
Based on a Groundbook review completed in November 2026. Findings are summarized.
Are these findings confirmed defects?
No. Each one is a potential issue for the responsible designer to verify against the source documents. Groundbook reports what the documents say and where they disagree. It does not make design decisions, certify compliance, or replace the authority having jurisdiction.
How long did the review take?
Turnaround runs from 20 minutes to 24 hours depending on project size.
Was a code check included?
No code check was enabled for this review. It covered coordination and completeness within the set. Code checking is available: Groundbook reads the building codes that governments publish online and uses licensed codes only where a license allows it. You can upload a copy you’re licensed to use.
Can I see a full report?
Yes. The sample plan review report shows all 79 findings from one review of a drawing set and its specifications, with the cited excerpts.
