Missing Neutral Conductor for 120V Convenience Receptacle at HVAC Units
Electrical
Note 5 of the HVAC Equipment Schedule directs the electrical contractor to connect a factory convenience outlet (which requires 120V) to the load side of the HVAC unit's disconnect. However, the schedule specifies the voltage for HP 1 through HP 4 as '208/3' and the branch circuits as '3#8 CU, 1#10 GND, 3/4” C.', which provides three ungrounded...
Insulated Ground Bus Specified in Service Entrance Switchboard
Electrical
The specifications for the Main Switchboard (Section 2.11.B) indicate it is rated for use as Service Entrance Equipment, but it requires an 'insulated ground bus extending the length of the switchboard'. An insulated ground bus is mounted on standoff insulators and is electrically isolated from the metallic enclosure. This directly conflicts...
Double Door at Elevation A Fails to Provide Minimum 32-Inch Clear Width
Architectural
Elevation A details a storefront assembly with a set of symmetrical double doors dimensioned at 5'-2' (62 inches) in total width. Because the doors are symmetrical, each manual door leaf is nominally 31 inches wide. Accessible routes, which include doors and doorways (Section 402.2), require a clear width of 36 inches minimum, but can be...
Keynote 214 defers wall insulation to 'FUTURE' while acknowledging it is needed to meet energy code requirements
Architectural
Keynote 214 on the floor plan states: 'LINE OF FUTURE STUD FURRING OVER EXTERIOR MASONRY WALLS W/ MIN. R-11 BATT INSULATION TO MEET ENERGY CODE REQUIREMENTS.' The word 'FUTURE' indicates the insulation is not part of the current construction scope. However, the note itself explicitly acknowledges this insulation is required 'TO MEET ENERGY CODE...
Fire-rated penetration sealing specification requires only 'sealants' instead of listed penetration firestop systems...
Plumbing
The plumbing specification Section 3.02.W states that piping passing through fire-rated walls, floors, and ceilings must be 'adequately sealed' and directs the contractor to 'provide the required sealants at penetrations.' However, IBC Section 714.2 explicitly requires 'A listed penetration firestop system shall be installed in accordance with...
Roll-Down Security Shutters Conceal Exterior Means of Egress Doors
Architectural
Keynote 212 specifies that exterior roll-down metal security shutters will be installed at typical exterior door locations. The building code strictly requires that means of egress doors remain readily distinguishable and easily recognizable as doors, explicitly prohibiting them from being concealed by 'curtains, drapes, decorations or similar...
Mechanical Note 11 specifies 10-inch separation between air intakes and exhaust outlets; code requires 10 feet
Mechanical
Mechanical Note 11 on sheet M2.0 states a minimum clearance of 10 inches (10') between fresh air intakes and exhaust outlets, relief outlets, and plumbing vents. Section 501.3.1, Item 3 of the 2018 IMC requires environmental air exhaust terminations to be located not less than 10 feet (3048 mm) from mechanical air intakes. The drawing specifies...

However, the schedule specifies the voltage for HP 1 through HP 4 as '208/3' and the branch circuits as '3#8 CU, 1#10 GND, 3/4” C.', which provides three ungrounded...
Why it matters: If the 120V GFCI convenience receptacle is wired as instructed without a neutral, it creates a severe shock hazard by energizing the grounding system. The contractor will be physically unable to provide a compliant 120V receptacle at the HP units using only the 3-wire feeder provided. This will cause delays and require a change order to either...
Suggested next step: Please clarify how the 120V convenience receptacles for the HP units should be powered. Should the branch circuits in the HVAC Equipment Schedule be revised to include a neutral conductor, or should separate dedicated 120V circuits be provided to each unit? If separate circuits are added, please revise Note 5.

An insulated ground bus is mounted on standoff insulators and is electrically isolated from the metallic enclosure. This directly conflicts...
Why it matters: If the primary equipment grounding bus provided in the main service switchboard is electrically isolated from the enclosure, the enclosure itself may remain ungrounded. This defeats the effective ground-fault current path required for service equipment, creating a severe shock and life safety hazard. The installation would fail electrical...
Suggested next step: Please confirm if the main ground bus in the service entrance switchboard should be uninsulated and solidly bonded to the enclosure, as required for Service Entrance Equipment. If an isolated ground bus is needed for specific downstream isolated-ground circuits, it should be specified in addition to the primary bonded equipment ground bus.

Because the doors are symmetrical, each manual door leaf is nominally 31 inches wide. Accessible routes, which include doors and doorways (Section 402.2), require a clear width of 36 inches minimum, but can be...
Why it matters: Fabricating and installing a 5'-2' double door will create a hard barrier for wheelchair users, as neither leaf can provide the required 32-inch clear width. This non-compliant assembly will fail accessibility inspections, leading to significant delays and cost overruns because the entire storefront frame and doors at Elevation A would need to...
Suggested next step: Please review the 5'-2' dimension for the double doors in Elevation A. Confirm if the overall assembly width should be increased to accommodate two compliant 36-inch leaves, or if the doors should be changed to an unequal pair (e.g., one 36-inch active leaf and one 26-inch inactive leaf) to ensure at least one leaf provides the required minimum...

Summary: Keynote 214 on the floor plan states: 'LINE OF FUTURE STUD FURRING OVER EXTERIOR MASONRY WALLS W/ MIN. R-11 BATT INSULATION TO MEET ENERGY CODE REQUIREMENTS.' The word 'FUTURE' indicates the insulation is not part of the current construction scope. However, the note itself explicitly acknowledges this insulation is required 'TO MEET ENERGY CODE...
Why it matters: This issue would likely result in plan review rejection or denial of a certificate of occupancy by the authority having jurisdiction. Energy code compliance must be demonstrated at the time of construction, not deferred to an unscheduled future phase. If the insulation is not installed, the building's thermal envelope will not meet the IECC...
Suggested next step: Clarify the intent of Keynote 214 regarding the 'FUTURE' designation for the stud furring and R-11 batt insulation on exterior masonry walls. Per IBC Section 1301.1.1, the building must be designed and constructed in accordance with the IECC. Please confirm whether this insulation will be included in the current construction scope to achieve...

Fire-rated penetration sealing specification requires only 'sealants' instead of listed penetration firestop systems...PlumbingCritical
Summary: The plumbing specification Section 3.02.W states that piping passing through fire-rated walls, floors, and ceilings must be 'adequately sealed' and directs the contractor to 'provide the required sealants at penetrations.' However, IBC Section 714.2 explicitly requires 'A listed penetration firestop system shall be installed in accordance with...
Why it matters: This discrepancy could lead contractors to install generic sealants or caulk at fire-rated penetrations rather than UL-listed firestop systems, which would fail fire inspection. Rework to remove non-compliant sealants and install proper listed firestop systems after piping is already in place is costly and time-consuming. Fire inspectors...
Suggested next step: Request that Specification Section 3.02.W be revised to require that all penetrations of fire-resistance-rated assemblies be protected with a listed penetration firestop system installed in accordance with the manufacturer's installation instructions and the listing criteria, per IBC Section 714.2. The specification should also require the...

Roll-Down Security Shutters Conceal Exterior Means of Egress DoorsArchitecturalCritical
Summary: Keynote 212 specifies that exterior roll-down metal security shutters will be installed at typical exterior door locations. The building code strictly requires that means of egress doors remain readily distinguishable and easily recognizable as doors, explicitly prohibiting them from being concealed by 'curtains, drapes, decorations or similar...
Why it matters: If the metal security shutters are deployed (rolled down) while the building is occupied, they completely hide and block the egress path, creating a severe life-safety hazard and entrapment risk during a fire or emergency. This will typically result in failed building and fire marshal inspections.
Suggested next step: Please clarify the operation of the roll-down shutters at exterior egress doors. To comply with IBC 1010.1, either remove the shutters from required means of egress doors or provide an approved design demonstrating how the doors remain unconcealed, fully operable, and distinguishable whenever the space is occupied.

Mechanical Note 11 specifies 10-inch separation between air intakes and exhaust outlets; code requires 10 feetMechanicalCritical
Summary: Mechanical Note 11 on sheet M2.0 states a minimum clearance of 10 inches (10') between fresh air intakes and exhaust outlets, relief outlets, and plumbing vents. Section 501.3.1, Item 3 of the 2018 IMC requires environmental air exhaust terminations to be located not less than 10 feet (3048 mm) from mechanical air intakes. The drawing specifies...
Why it matters: If equipment is installed per this note, fresh air intakes could be placed only 10 inches from exhaust outlets, resulting in direct re-entrainment of contaminated exhaust air into the building supply system. This violates both Section 501.3.1 (exhaust discharge location) and Section 401.4, Item 2 (intake opening location requiring 10 feet from...
Suggested next step: Request the engineer confirm the intended separation distance between outdoor air intakes and exhaust/relief outlets. Mechanical Note 11 currently specifies 10 inches, which conflicts with 2018 IMC Section 501.3.1, Item 3 requiring a minimum 10-foot separation from mechanical air intakes. Revise the note to require a minimum 10-foot (120-inch)...

Summary: Mechanical Note 11 on sheet M2.0 states to 'PROVIDE A MINIMUM OF 10' CLEARANCE BETWEEN FRESH AIR INTAKE AND EXHAUST OUTLETS, RELIEF OUTLETS, PLUMBING VENTS, ECT.' This specifies only 10 inches of separation between fresh air intakes and plumbing vent terminals. IPC Section 903.5 requires that an open vent terminal from a drainage system 'shall...
Why it matters: If constructed per this note, plumbing vent terminals could be placed as close as 10 inches from HVAC outdoor air intakes. This would allow sewer gases from the drainage system vent to be drawn directly into the building's HVAC fresh air supply, creating a health hazard for occupants. This violation would be identified during...
Suggested next step: Request the engineer clarify Mechanical Note 11 regarding the separation distance between fresh air intakes and plumbing vents. Per IPC Section 903.5, plumbing vent terminals must be not less than 10 feet horizontally from any air intake opening of the building, unless the vent terminal is 3 feet or more above the top of the opening. The note...

Contradictory Exterior Elevation Titles and OrientationsArchitecturalCritical
Summary: The floor plan on A120 and the key plan on A210 specify elevation marker 1 for the South wall, 2 for the West wall, 3 for the North wall, and 4 for the East wall. However, the elevation details on A210 have misaligned titles that contradict this orientation: Detail 1 is titled 'WEST EXTERIOR ELEVATION', Detail 2 is titled 'NORTH EXTERIOR...
Why it matters: Misidentifying the building elevations causes severe coordination issues, as the contractor will reference the wrong sides of the building for exterior finishes, door and window placements, and structural openings. This can result in costly rework and delays.
Suggested next step: Please revise the titles of the exterior elevations on sheet A210 to match the corresponding orientations shown in the floor plan callouts on A120 and the key plan on A210 (e.g., re-title Detail 1 to South Elevation, Detail 2 to West Elevation, etc.).

Mismatched Architectural Enlarged Site Plan Reference and Building ScopeArchitecturalCritical
Summary: The Overall Site Plan (A100) labels Building 1 as 'N.I.C.' and points the Enlarged Site Plan callout ('1/A101') directly to Building 3 in the southern portion of the site. However, the Enlarged Site Plan (A101) illustrates a building footprint, parking configuration (parking to the south), and trash enclosure location that exactly match Lot...
Why it matters: This severe cross-referencing contradiction creates fundamental confusion regarding the project's physical scope. If Building 3 is the intended building for this permit, the Architectural Enlarged Site Plan (A101) illustrates the completely wrong building geometry and site layout. If Building 1 is the intended scope, it should not be labeled...
Suggested next step: Please clarify which building (Building 1/Lot 1 or Building 3/Lot 3) is currently in scope for this drawing set. Update the Overall Site Plan (A100) detail callouts and 'N.I.C.' designations accordingly, or revise the Enlarged Site Plan (A101) to accurately reflect the correct building footprint and site layout.

Incorrect Location of Control Joints in Lintels at Mid-SpanStructuralCritical
Summary: Drawing S0.5, Detail 17, Note B explicitly directs that 'CONTROL JOINTS IN LINTELS SHALL BE LOCATED AT MID-SPAN U.N.O.' This is a severe structural mistake according to standard masonry engineering practice. A lintel is a flexural member that experiences its maximum bending moment and maximum compressive stresses at mid-span. Locating a control...
Why it matters: If constructed as detailed, the lintel will lack the necessary compressive continuity to transfer flexural loads across the opening, which could lead to hinging, cracking, or catastrophic failure of the lintel under load.
Suggested next step: Please revise Detail 17, Note B to prohibit locating control joints within the span of lintels, and clarify that control joints must be located at the jambs or outside the span to maintain structural integrity.

HVAC branch circuit conductor sizes specified without required rooftop temperature derating per NEC 310.15(B)ElectricalHigh
Summary: The HVAC Equipment Schedule specifies branch circuit conductors for rooftop-mounted heat pumps HP-1 through HP-3 (28 MCA, 208/3) and HP-4 (30 MCA, 208/3) as '3#8 CU, 1#10 GND, 3/4' C.' Schedule Note 4 explicitly states these wire sizes are 'BASED UPON TABLE 310.15(B)(16) NOT DE-RATED' while simultaneously requiring derating for ambient...
Why it matters: This discrepancy will cause construction delays because the electrical contractor cannot install the conductor and conduit sizes shown in the schedule without first determining the correct derated sizes through calculation. The specified 3/4' conduit may also be inadequate if conductors must be upsized to meet derated ampacity requirements,...
Suggested next step: Request the engineer of record provide final derated conductor and conduit sizes for all rooftop HVAC branch circuits (HP-1 through HP-4 and EF-1), accounting for ambient temperature correction per NEC 310.15(B) for 117–122°F conditions and rooftop sun exposure temperature adder, as acknowledged in HVAC Equipment Schedule Note 4. The branch...

Accessible Parking Sign Specifies 1/4' Character Height, Code Requires 5/8' MinimumArchitecturalHigh
Summary: Detail 21 (ACCESSIBLE PARKING SIGN) specifies '1/4' high letters as shown' for the sign text. Note 1 of the same detail states the bottom of the sign shall be no less than 60 inches above finish grade. With the sign bottom at 60' and the sign being 18' tall, the character baselines range from approximately 60' to 76' above grade. Per ANSI/ICC...
Why it matters: Signs fabricated with 1/4' characters will fail accessibility plan review or field inspection, requiring redesign and re-fabrication of all accessible parking signs. This can delay final inspections and certificate of occupancy, as parking accessibility is a common inspection checkpoint.
Suggested next step: Request the designer revise the accessible parking sign detail (Detail 21) to specify character heights that comply with Table 703.2.4 of ANSI/ICC A117.1-2009. Characters with baselines between 40' and 70' above finish grade require a minimum height of 5/8', and characters with baselines above 70' require a minimum height of 2'. Confirm all...

Keynote 107 incorrectly specifies 'DETACHABLE Warning Surface' instead of code-required 'DETECTABLE Warning Surface'ArchitecturalHigh
Summary: Keynote 107 on the Enlarged Site Plan reads 'ACCESSIBLE CURB RAMP WITH DETACHABLE WARNING SURFACE.' The correct code term per ANSI/ICC A117.1-2009 Section 705 is 'Detectable Warning Surfaces,' which are tactile surfaces with truncated domes intended to be detected underfoot or by cane. 'Detachable' means removable or able to be separated, which...
Why it matters: This terminology error on the architectural site plan could cause confusion during procurement and construction. A contractor reading 'detachable warning surface' may question the specification, order the wrong product, or delay installation seeking clarification. Since this keynote is a primary instruction on the architectural enlarged site...
Suggested next step: Request that the architect correct Keynote 107 to read 'ACCESSIBLE CURB RAMP WITH DETECTABLE WARNING SURFACE' in accordance with ANSI/ICC A117.1-2009 Section 705, and verify that the curb ramp detail on the civil drawings also specifies detectable warning surfaces with truncated domes complying with Section 705.5.
