Keynote specifies 36' handrail/guardrail height (guards must be 42' min)
Architectural • IBC
The Level 1 plan keynotes specify a '36\' FLAT TOP HANDRAIL/GUARDRAIL'. Where this element functions as a guard, IBC requires required guards to be at least 42 inches high. A 36-inch guard height would not comply.
Guardrail shown as 36-inch high conflicts with IBC 42-inch minimum guard height
Architectural • IBC
The elevation keynotes specify a '36\' FLAT TOP HANDRAIL/GUARDRAIL' (Keynote 17). Where this element functions as a guard (it is explicitly labeled 'GUARDRAIL' and is called out at exterior ramp/guardrail areas), the 2024 IBC requires guards to be a minimum of 42 inches high. A 36-inch guard height is noncompliant.
36-inch “handrail/guardrail” note conflicts with 42-inch minimum guard height
Architectural • IBC
The plan keynotes specify a “36\' FLAT TOP HANDRAIL/GUARDRAIL.” Where the element functions as a guard (i.e., a guardrail), the IBC minimum required guard height is 42 inches. A 36-inch guardrail height is therefore noncompliant.
Keynote 12 specifies 36-inch HANDRAIL/GUARDRAIL height; may conflict with 42-inch minimum for required guards (IFC...
Architectural
The Level 2 plan keynotes list Keynote 12 as a '36\' FLAT TOP HANDRAIL/GUARDRAIL' with cable infill. IFC 1015.3 requires required guards to be not less than 42 inches high. If Keynote 12 is intended to serve as a required guard at any location, the noted 36-inch height would not meet the 42-inch minimum.
Finish floor elevation discrepancy between C4.0 (F.F.E. 693.75') and C4.1 label (FF 691.5)
Civil
Sheet C4.0 labels the proposed Mercedes-Benz of Austin facility building footprint with finish floor elevation 'F.F.E. = 693.75''. Sheet C4.1 (Exist. Drainage Area Map) contains a 'PROPOSED BUILDING' label with 'FF 691.5'. These finish-floor-related elevations differ by 2.25'. It is not clear from the provided excerpts whether the C4.1 'FF...
Sprinkler supervision note incorrectly limits monitoring to systems over 100 sprinklers
General • IBC
The General Sheet Notes state that only an automatic sprinkler system “SERVING MORE THAN 100 SPRINKLERS” must be supervised, and it allows supervision by “A LOCAL ALARM” at a constantly attended location. IBC 2024 requires automatic sprinkler systems to be monitored by an approved supervising station, with exceptions only for one- and...
Door clearance detail implies 2'-8' door achieves 32' clear opening (can undersize egress doors)
Architectural • IBC
The 'CLEAR DOORWAY WIDTH HINGED DOOR' diagram pairs a '32\' MIN. CLR. OPENING' requirement with a '2'-8\'' door size callout, implying a 2'-8' hinged door provides the required 32' clear opening. IBC requires the 32' minimum to be the clear opening measured between the face of the door and the frame stop with the door open 90 degrees; that...
Egress capacity factors mislabeled in feet instead of inches (Life Safety Analysis)
Architectural • IBC
The Code Life Safety Analysis text states the means of egress sizing factors as feet per occupant (e.g., '0.2' PER OCCUPANT' and '0.3' PER OCCUPANT'). The 2024 IBC requires egress capacity to be calculated in inches, and stairway capacity specifically uses '0.3 inch ... per occupant.' This is a direct contradiction of IBC-required units and can...
Energy compliance references ASHRAE 90.1-2022 instead of IECC as required by IBC 1301.1.1
Architectural • IBC
The submitted COMcheck documentation explicitly identifies the project 'Energy Code' as '90.1 (2022) Standard.' However, IBC 2024 Section 1301.1.1 requires buildings be designed and constructed in accordance with the International Energy Conservation Code (IECC), not ASHRAE 90.1 as the stated governing code on this sheet.

Keynote specifies 36' handrail/guardrail height (guards must be 42' min)Architectural • IBCCritical
Summary: The Level 1 plan keynotes specify a '36\' FLAT TOP HANDRAIL/GUARDRAIL'. Where this element functions as a guard, IBC requires required guards to be at least 42 inches high. A 36-inch guard height would not comply.
Why it matters: If installed at 36 inches where a code-required guard is needed, this will fail inspection and require re-fabrication/re-installation of the guard system (schedule and cost impact), and creates a life-safety fall-protection deficiency.
Suggested next step: Confirm whether Keynote 12 is intended to be a code-required guard. If it is a guard, revise the design/detail and specification to provide a minimum 42-inch guard height per IBC 1015.3. If 36 inches is intended only as a handrail height, clarify by separating handrail vs. guard requirements and indicate a compliant guard height where required.

Guardrail shown as 36-inch high conflicts with IBC 42-inch minimum guard heightArchitectural • IBCCritical
Summary: The elevation keynotes specify a '36\' FLAT TOP HANDRAIL/GUARDRAIL' (Keynote 17). Where this element functions as a guard (it is explicitly labeled 'GUARDRAIL' and is called out at exterior ramp/guardrail areas), the 2024 IBC requires guards to be a minimum of 42 inches high. A 36-inch guard height is noncompliant.
Why it matters: If built as shown, this will fail inspection for fall protection and likely require removal and replacement/rework of the exterior guard/rail system, causing cost and schedule impacts and potentially delaying occupancy.
Suggested next step: Confirm whether Keynote 17 is intended to serve as a code-required guard at exterior ramps/landings/walking surfaces. If it is a guard, revise the design/details and specifications to provide a minimum 42-inch guard height per IBC (and coordinate any separate handrail requirements as applicable).

36-inch “handrail/guardrail” note conflicts with 42-inch minimum guard heightArchitectural • IBCCritical
Summary: The plan keynotes specify a “36\' FLAT TOP HANDRAIL/GUARDRAIL.” Where the element functions as a guard (i.e., a guardrail), the IBC minimum required guard height is 42 inches. A 36-inch guardrail height is therefore noncompliant.
Why it matters: This is a life-safety fall-protection issue. If fabricated/installed at 36 inches, it will fail inspection and require rework/replacement of guard assemblies and associated detailing (posts, glazing/cable infill, attachments), causing schedule delays and cost overruns.
Suggested next step: Clarify whether Keynote 12 is intended to be (a) a required guard (provide guard height ≥ 42 inches), or (b) a handrail only (then show a separate compliant 42-inch-high guard where required). Revise the keynote and associated details/specifications accordingly.

Summary: The Level 2 plan keynotes list Keynote 12 as a '36\' FLAT TOP HANDRAIL/GUARDRAIL' with cable infill. IFC 1015.3 requires required guards to be not less than 42 inches high. If Keynote 12 is intended to serve as a required guard at any location, the noted 36-inch height would not meet the 42-inch minimum.
Why it matters: If this assembly is installed at 36 inches in a location where a guard is required, it is likely to fail inspection and require rework (removal/replacement or redesign), with associated schedule and cost impacts—especially for fabricated guard components such as cable infill and top-mounted assemblies.
Suggested next step: Please confirm whether Keynote 12 'HANDRAIL/GUARDRAIL' is intended to function as a required guard at any location. If it is a required guard, revise the detail/keynote to provide a minimum 42-inch guard height per IFC 1015.3 and coordinate with any referenced details/specifications.

Finish floor elevation discrepancy between C4.0 (F.F.E. 693.75') and C4.1 label (FF 691.5)CivilCritical
Summary: Sheet C4.0 labels the proposed Mercedes-Benz of Austin facility building footprint with finish floor elevation 'F.F.E. = 693.75''. Sheet C4.1 (Exist. Drainage Area Map) contains a 'PROPOSED BUILDING' label with 'FF 691.5'. These finish-floor-related elevations differ by 2.25'. It is not clear from the provided excerpts whether the C4.1 'FF...
Why it matters: If the C4.1 'FF 691.5' is being relied upon for current civil grading/drainage coordination, a 2.25' discrepancy could affect site grading, drainage flow paths, tie-ins to existing pavement/curb, ADA slopes, and utility elevations.
Suggested next step: Confirm the correct finish floor elevation basis for the proposed Mercedes-Benz facility building and clarify whether the C4.1 'FF 691.5' note applies to this project/building. Update the applicable sheet(s) (or add a clarification note) so finish floor elevations are consistent or clearly identified as legacy/non-applicable information.

Sprinkler supervision note incorrectly limits monitoring to systems over 100 sprinklersGeneral • IBCHigh
Summary: The General Sheet Notes state that only an automatic sprinkler system “SERVING MORE THAN 100 SPRINKLERS” must be supervised, and it allows supervision by “A LOCAL ALARM” at a constantly attended location. IBC 2024 requires automatic sprinkler systems to be monitored by an approved supervising station, with exceptions only for one- and...
Why it matters: If the project relies on this note, the fire alarm/sprinkler scope could be under-designed (missing supervising-station monitoring), leading to plan review comments, failed acceptance testing/inspection, and change orders to add monitoring hardware/services late in the project.
Suggested next step: Revise the general note to match IBC 2024 Section 901.6.1 (monitoring by an approved supervising station per NFPA 72), and remove the “more than 100 sprinklers” threshold and the allowance for a “local alarm” in lieu of supervising-station monitoring unless the design team confirms a code exception applies and identifies it explicitly on the...

Summary: The 'CLEAR DOORWAY WIDTH HINGED DOOR' diagram pairs a '32\' MIN. CLR. OPENING' requirement with a '2'-8\'' door size callout, implying a 2'-8' hinged door provides the required 32' clear opening. IBC requires the 32' minimum to be the clear opening measured between the face of the door and the frame stop with the door open 90 degrees; that...
Why it matters: If door sizes are selected/installed using this standard detail, openings can fail building inspection for means of egress and accessibility, requiring door/frame replacement and rework (schedule and cost impact).
Suggested next step: Revise the 'CLEAR DOORWAY WIDTH HINGED DOOR' standard detail to show a door size that reliably provides a 32' minimum clear opening per IBC measurement method (between door face and frame stop at 90 degrees), and/or explicitly dimension and specify the required clear opening on door schedules and typical details.

The 2024 IBC requires egress capacity to be calculated in inches, and stairway capacity specifically uses '0.3 inch ... per occupant.' This is a direct contradiction of IBC-required units and can...
Why it matters: Because this is on the project’s code/life-safety summary, a unit error can trigger plan review comments, require resubmittals, and create contractor confusion about required egress widths, causing schedule delays and potential rework if door/stair widths are selected based on the incorrect unit labeling.
Suggested next step: Revise the Code Life Safety Analysis to state egress capacity factors in inches per occupant per IBC 1005.3 and 1005.3.1 (e.g., 0.2 inch/occupant for other egress components and 0.3 inch/occupant for stairways, as applicable), and confirm all required egress width calculations are based on inches (not feet).

Energy compliance references ASHRAE 90.1-2022 instead of IECC as required by IBC 1301.1.1Architectural • IBCHigh
Summary: The submitted COMcheck documentation explicitly identifies the project 'Energy Code' as '90.1 (2022) Standard.' However, IBC 2024 Section 1301.1.1 requires buildings be designed and constructed in accordance with the International Energy Conservation Code (IECC), not ASHRAE 90.1 as the stated governing code on this sheet.
Why it matters: If the authority having jurisdiction is enforcing IECC compliance per IBC Chapter 13, an energy submittal that is explicitly based on ASHRAE 90.1 (2022) can be rejected during plan review, requiring resubmittal and potentially delaying permit issuance.
Suggested next step: Confirm which energy code compliance path is required by the AHJ for this permit (IECC per IBC 1301.1.1 vs. an approved ASHRAE 90.1 compliance alternative). If IECC is required, revise and resubmit the energy compliance documentation to demonstrate IECC compliance (or provide documentation showing the AHJ-approved basis for using ASHRAE 90.1-2022).

Grading notes cite TAS/2010 ADA but do not reference 2024 IBC + ICC A117.1 accessibility standardCivil • IBCHigh
Summary: On sheet C3.0, the grading notes require accessibility-related work to comply with the “2012 TEXAS ACCESSIBILITY STANDARDS (TAS)” and the “2010 ADA STANDARDS FOR ACCESSIBLE DESIGN,” and further state that routes/grades for sidewalks, ramps, aprons, and pedestrian routes shall meet TAS/ADA criteria. The referenced IBC accessibility provision...
Why it matters: If the project is being reviewed/permitted under an IBC pathway that relies on ICC A117.1, having civil grading notes that only cite TAS/ADA can trigger plan review clarification requests and potential redesign/regrading of accessible routes, sidewalks/ramps, and related site elements, causing permitting delays and rework.
Suggested next step: Confirm the governing accessibility standard(s) for this project’s permit/AHJ. If IBC + ICC A117.1 governs, revise the grading/general notes to reference 2024 IBC Chapter 11 and ICC A117.1 (and list TAS/ADA only where explicitly required by the AHJ and not in conflict). If TAS/ADA is intended to govern in lieu of ICC A117.1, provide written AHJ...

Keynote 17 calls out 36' handrail/guardrail; verify compliance with IBC 42' minimum where a guard is requiredArchitectural • IBCHigh
Summary: The exterior elevation keynotes include Keynote 17: '36\' FLAT TOP HANDRAIL/GUARDRAIL'. IBC 1015.3 states that required guards shall be not less than 42 inches high. If Keynote 17 is used where a code-required guard is required, the indicated 36-inch height would not meet the 42-inch minimum.
Why it matters: If this assembly is installed at an open-sided walking surface where a guard is required, a 36-inch height would create a potential life-safety/code compliance concern and could trigger plan review/inspection comments and rework.
Suggested next step: Confirm whether Keynote 17 is intended to serve as a required guard at any open-sided walking surface. If it is a required guard, revise the detail/specification to provide a minimum 42-inch guard height (or otherwise demonstrate compliance). If it is only a handrail, revise the keynote to remove 'guardrail' language and provide a separate...

Guardrail height noted as 36' but IBC requires 42' minimum for guardsArchitectural • IBCHigh
Summary: The interior elevation keynotes call for a '36\' FLAT TOP HANDRAIL/GUARDRAIL'. Where this rail is functioning as a guard, the 2024 IBC requires guards to be at least 42 inches high. A 36-inch-high guardrail does not comply.
Why it matters: If fabricated/installed at 36 inches, this is a life-safety noncompliance and is likely to fail plan review/inspection, requiring refabrication or modification of the rail system (cost/schedule impact).
Suggested next step: Confirm whether this element is intended to serve as a code-required guard. If yes, revise details/spec to provide a minimum 42-inch guard height (or provide a separate compliant guard with a separate handrail as allowed) and update affected elevations/notes accordingly.

Guardrail noted as 36 inches high conflicts with IBC minimum 42-inch guard heightArchitectural • IBCHigh
Summary: The interior elevation keynotes specify a '36\' FLAT TOP HANDRAIL/GUARDRAIL'. When this element functions as a guard, the IBC requires guards to be at least 42 inches high. The noted 36-inch guardrail height therefore does not meet the code minimum for guards.
Why it matters: If constructed at 36 inches where a code-compliant guard is required, this will likely be rejected during inspection and require removal and re-fabrication/re-installation of the rail system, causing schedule impacts and added cost.
Suggested next step: Confirm whether Keynote 11 is intended to serve as a required guard. If it is a guard, revise the design/details to provide a minimum 42-inch guard height per IBC. If it is only a handrail (not a guard), revise the note to remove 'guardrail' language and provide a separate code-compliant guard where required.

Guardrail height called out as 36 inches (below IBC 42-inch minimum for required guards)Architectural • IBCHigh
Summary: The interior elevation keynotes explicitly call out a '36\' FLAT TOP HANDRAIL/GUARDRAIL.' Where this rail functions as a guard, IBC requires required guards to be at least 42 inches high. A 36-inch guardrail height conflicts with the minimum required guard height.
Why it matters: If constructed at 36 inches where a guard is required, this is a life-safety code noncompliance and is likely to be rejected at inspection, potentially requiring redesign/refabrication and reinstallation of the guard/rail system (including cable infill and attachments).
Suggested next step: Confirm whether Keynote 11 is intended to serve as a required guard. If it is a guard, revise the design to provide a minimum 42-inch-high guard (or provide a separate code-compliant guard) and update the guard/handrail details accordingly.
