The roof plan shows a parapet construction around the roof perimeter, which creates a condition where water can be entrapped. While primary roof drains are indicated at valley low points (circular symbols), there are no corresponding secondary (emergency overflow) drains or scuppers shown at the main drainage locations.
The drawing plans for Restrooms 108, 304, and 306 show doors located in corners with the latch side adjacent to a perpendicular wall. Drawing Note 7 explicitly sets this dimension to "MINIMUM OF 4 INCHES". This contradicts the accessibility requirements for maneuvering clearance at manual swinging doors. Per the referenced Building Code (which mandates accessibility compliance), doors require a minimum of 18 inche...
The drawing explicitly instructs condensate to "spill onto the roof". IBC 1503.1 requires roof coverings to be installed in accordance with the manufacturer's approved instructions. The vast majority of roof membrane manufacturers (TPO, EPDM, etc.) prohibit the continuous discharge of HVAC condensate directly onto the roof surface as it can cause membrane deterioration, algae growth, and void the warranty.
General Note 1.I explicitly instructs the remote monitoring station to "call out to call list provided by the Owner" upon receipt of fire alarm signals. This specific sequence of operations omits the mandatory requirement for the supervising station to immediately retransmit alarm signals to the public fire service communications center (Fire Department). By defining a procedure that only references a "Call List,"...
The drawing Key Note T1 explicitly specifies a '20'-0" 2" C. MAST' to be provided and anchored to the structural steel. A 20-foot tall mast constructed of 2-inch diameter material (conduit or pipe) is structurally insufficient to withstand wind loads required by IBC Section 1609 and the TIA 222 standard mandated by IBC Section 3108.1. Due to the high slenderness ratio and lack of bracing or guy wires shown, this s...
The 'Lighting Requirements' note explicitly states that 'all illuminated signs shall have dimmers with localized controls'. The sign package includes 'Overhead Sign Boxes' (A-1) and 'Terminal, Directional' sign faces (ST-101 - ST-150) which typically serve as required means of egress signage (directional exit signs). IBC Section 1013.5 requires that exit signs be 'illuminated at all times' to ensure continuous vis...
P2.10 depicts the north wall horizontal main piping labeled as "4"SAN" (Sanitary), which is further confirmed by Keynote 11 ("4"SAN UP TO FLOOR CLEAN OUT") attached to it. However, the same drawing shows Keynote 10 ("4"ST UP") attached to risers connecting to this sanitary line. P2.11 confirms these risers are intended to be Storm, labeled "4" ST DN & RISE". Connecting Storm risers to a Sanitary main is a system c...
Detail 1 specifies "Spray Foam" (foam plastic insulation) within the exterior column joint. However, the detail does not show or label a thermal barrier (such as 1/2-inch gypsum wallboard) separating the foam plastic from the interior of the building. This violates IBC 2603.4, which mandates that foam plastic be separated from the interior by an approved thermal barrier to ensure fire safety.
The building sections depict multiple interior occupied spaces (e.g., "RESTROOM", "PRIVATE SCREENING", "SECURITY SCREENING", "OFFICE") that are enclosed without access to exterior openings for natural ventilation. IMC 401.2 requires every occupied space to be ventilated. Since natural ventilation (IMC 402) is not feasible for these interior rooms, mechanical ventilation is required per IMC 403.1. Furthermore, IMC...
IBC Section 907.2 requires that not fewer than one manual fire alarm box be provided in an approved location to initiate a fire alarm signal. The Fire Alarm Construction Plan shows detailed locations for the Fire Alarm Control Panel (FACP), Annunciator, and automatic detectors, but fails to indicate a manual fire alarm box (pull station), typically required near the main exit or FACP.
The roof screen structural framing lacks a complete lateral force-resisting system in the transverse direction. The Plan view shows X-bracing (RS members) only in the longitudinal direction (Grid 1-8). Section B-B (the transverse view) depicts a rectangular frame with 'SHS60x60' columns and 'IPE140' beams. The column bases are detailed as simple 4-bolt pads (pinned bases) and the beam-to-column connections are sho...
The "CIRCUIT AND CONDUIT SCHEDULE" (Row G) explicitly specifies the conduit/installation method for "AC POWER TO PANELS" as "FREE-AIR" in both "INDOOR - CONCEALED IN NON-ACCESSIBLE WALLS/CEILINGS" and "INDOOR - CONCEALED IN ACCESSIBLE WALLS/CEILINGS". This contradicts IMC 602.2.1 which requires materials within plenums to be noncombustible or listed for such use (e.g., having a flame spread index of not more than...
The details depict structural steel column members (shown as HSS clusters) wrapped directly in plywood and trim without any indication of fire-resistive materials (such as gypsum board encasement or spray-applied fireproofing). IBC Table 601 requires the Primary Structural Frame to have a fire-resistance rating (typically 1-3 hours for Types I, IIA, IIIA, etc.). The absence of fire protection in the detail implies...
The drawing details a "Demising Wall" (implying a fire-resistance-rated assembly, further evidenced by the "Continuous Fire Tape" note) intersecting the underside of a metal roof deck. The detail explicitly calls for "Polyiso Flute Inserts" to fill the metal deck flutes directly above the wall. Polyisocyanurate is a combustible foam plastic. Code Section 715.3 requires joints at the intersection of fire-resistance...
Detail 4 (Enlarged Detail @ Skirt) clearly depicts the exterior wall assembly layers. From exterior to interior (Left to Right), the assembly includes 'DIRECT APPLIED SIDING', 'SELF-ADHERED AWB', '1/2" PLY', and 'INSULATED SHEATHING' positioned inboard of the plywood, adjacent to the steel beam and 'LIGHT GAUGE METAL FRAMING PANEL'. This places the foam plastic insulation on the interior side of the assembly, effe...
The 'OVERFLOW SCUPPER' openings shown on the elevations are drawn as small rectangular slots. When compared visually to the adjacent 1'-4 1/2" parapet height dimension and 1'-6" typical dimensions, the opening height appears to be significantly less than the code-mandated minimum of 4 inches.
IBC 1202.1 requires buildings to be provided with ventilation. The revised rooms ('TSA BREAK ROOM', 'TSA IT') show 'VRF' cassette units, which typically provide recirculation and temperature control but do not provide the required outdoor air ventilation unless specifically ducted (not shown). The Drawing Legend includes symbols for 'SUPPLY DIFFUSER' and 'RETURN REGISTER', but these symbols are missing from the re...
Detail 5 specifies a "STAINLESS STEEL ROUND ACCESS PANEL" for a vertical storm pipe cleanout but fails to indicate that this panel must be fire-rated when installed in fire-resistance-rated assemblies (such as shaft walls). This contradicts the requirement for opening protection in rated walls. By comparison, Detail 3 on the same sheet explicitly includes a note referring to fire-rated assembly details.
Detail 4 depicts a conduit penetration ("MINIMUM 3/4" CONDUIT STUBBED THROUGH EXTERIOR WALL") and mounting bolts for a Red Beacon on an exterior wall. However, the detail does not show or specify any flashing, sealant, or weather-resistant barrier integration at the penetration point. Installing the beacon as drawn (drilling holes without specified weatherproofing) would compromise the building envelope and violat...
Detail 1 depicts a 1" conduit penetrating an "EXTERIOR WALL" to serve an exterior Wireless Access Point. However, the detail fails to indicate any flashing, sealant, or weatherproofing method at the penetration point. This omission violates the code requirement for a weather-resistant exterior wall envelope, as unsealed penetrations allow water accumulation within the wall assembly.
