RFI draft: 📄 G0.01 Schedule Text: DRAWING INDEX — page 2 --- 📄 S100 Schedule Text: DRAWING INDEX — page 38

Summary: The floor plan designates 'DRESSING ROOM 129', 'DRESSING ROOM 126', 'RR 130', and 'RR 127' stacked vertically between horizontal grid lines 'C' and 'D'. The dimension string shows the total distance between 'C' and 'D' is '8'-11'' (107 inches). Because two rooms are stacked within this 107-inch space, the maximum internal vertical dimension of...

Why it matters: Failing to provide the required minimum dimensions prevents wheelchair access and maneuverability in restrooms and dressing rooms, violating fundamental accessibility requirements. This will cause failed inspections and necessitate costly demolition and structural layout changes during construction to resolve.

Suggested next step: Please revise the architectural plan to increase the vertical dimensions of Dressing Rooms 126 & 129 and Toilet Rooms 127 & 130 to accommodate the required 60-inch turning spaces and 60x56-inch water closet clearances.

Summary: The floor plan shows that room WH 147A is enclosed within or accessed solely through DRY-STOR. 147. Because DRY-STOR. 147 is a storage room, routing the only exit path for WH 147A through it directly violates IBC Section 1016.2 Item 5, which explicitly prohibits egress paths from passing through storage rooms. Additionally, if WH 147A requires...

Why it matters: Routing an egress path through a storage room traps occupants in a hazardous, high-combustible-load area during a fire emergency. This is a critical life safety violation that will result in a failed plan review and requires an architectural reconfiguration of the walls or doors to provide a direct exit access path.

Suggested next step: Please reconfigure the layout or relocate the door for WH 147A so that its egress path leads directly to a compliant exit access corridor or area without passing through DRY-STOR. 147.

RFI draft: Please reconfigure the layout or relocate the door for WH 147A so that its egress path leads directly to a compliant exit access corridor or area without passing through DRY-STOR. 147.

Summary: Detail 3 directs the contractor to 'BRING ROOF DRAINS AND OVERFLOWS THROUGH PAINTED CAST IRON PIPE'. IBC Section 1502.2 requires a secondary emergency overflow system to prevent water entrapment 'if the primary drains allow buildup for any reason.' Routing both the primary and overflow drains into a single shared pipe violates this fundamental...

Why it matters: Combining primary and overflow drains into one shared pipe is a severe defect that completely defeats the emergency overflow's purpose. In the event of a clog during a storm, the roof could accumulate water beyond its structural design capacity, risking a catastrophic roof collapse. This will be swiftly rejected by both the plumbing and...

Suggested next step: Please revise the details to provide completely independent piping and discharge paths for the primary roof drains and the secondary overflow drains, ensuring the overflow system functions properly if the primary pipe becomes obstructed.

RFI draft: Please revise the details to provide completely independent piping and discharge paths for the primary roof drains and the secondary overflow drains, ensuring the overflow system functions properly if the primary pipe becomes obstructed.

Summary: The floor plan shows two storage rooms (STORAGE 214 and STORAGE 217) with doors that open directly into the enclosed landings of STAIRS 212 and STAIRS 216, respectively. The Room Signage Schedule (Items 3 and 7) confirms these spaces are designated as storage rooms and the stairs are designated as 'EXIT' stairways. The building code strictly...

Why it matters: A storage room is not a normally occupied space providing exit access, and allowing it to open directly into an interior exit stairway introduces significant fire and smoke hazards into the protected means of egress. This violates the opening protective limitations and the fundamental requirement that exit stairways not be used for any purpose...

Suggested next step: Please revise the floor plan to remove the direct door connections between STORAGE 214 and STAIRS 212, and between STORAGE 217 and STAIRS 216. Ensure the storage rooms are accessed from the adjacent corridors or other non-stairway spaces, and that the interior exit stairway enclosures have no prohibited openings.

Ensure the storage rooms are accessed from the adjacent corridors or other non-stairway spaces, and that the interior exit stairway enclosures have no...

Summary: The exterior wall assembly EWA-1 specifies 4mm aluminum composite panels (MCM) over a suspension system applied directly over gypsum sheathing. The notes dictate that the sheathing is 'PAINTED MATTE BLACK AT EXPOSED JOINTS', which indicates an open-joint panel system where the sheathing itself is exposed to the elements between the panels....

Why it matters: In an open-joint metal composite material (MCM) cladding system, wind-driven rain will naturally pass through the exposed joints. Relying on painted gypsum sheathing as the weather barrier violates the building code's weather protection requirements. Without a continuous, UV-stable water-resistive barrier installed over the sheathing, water...

Suggested next step: Update the EWA-1 wall assembly specification to include a continuous, UV-stable water-resistive barrier (WRB) applied over the gypsum sheathing, properly flashed and suitable for an open-joint MCM cladding system, in accordance with IBC Section 1403.2.

RFI draft: Update the EWA-1 wall assembly specification to include a continuous, UV-stable water-resistive barrier (WRB) applied over the gypsum sheathing, properly flashed and suitable for an open-joint MCM cladding system, in accordance with IBC Section 1403.2.

Summary: The wall section detail explicitly lists the roof assembly layers as 'TPO ROOF SYSTEM OVER R−33 RIGID INSULATION OVER VAPOR BARRIER, OVER UNDERLAINMENT OVER METAL DECK.' Rigid insulation (foam plastic) must be separated from the interior of the building by an approved thermal barrier, such as 1/2-inch gypsum wallboard or a material passing NFPA...

Why it matters: Leaving foam plastic insulation without an approved thermal barrier is a severe life safety violation. Foam plastics can ignite easily and contribute to rapid fire spread across a roof deck assembly if exposed to interior fire conditions. This will lead to rejected building permits, failed inspections, and significant redesign or rework costs.

Suggested next step: Please confirm if the R-33 rigid insulation is a foam plastic. If so, revise the roof assembly detail to include an approved thermal barrier (such as 1/2-inch gypsum wallboard) installed below the foam plastic insulation, or provide UL/FM testing documentation proving the specific roof assembly complies with an approved exception to the thermal...

If so, revise the roof assembly detail to include an approved thermal barrier (such as 1/2-inch gypsum wallboard) installed below the foam plastic insulation, or provide UL/FM testing documentation proving the specific roof assembly...

Summary: Detail 3/A4.02 shows a 'TBK GLAZED BALUSTRADE' along Corridor 211 with a top elevation of '2'-5\' A.F.F.' (29 inches). The floor plan indicates this corridor overlooks an area that is 'OPEN TO BELOW', meaning the balustrade functions as a guard along an open-sided walking surface. IBC Section 1015.2 requires guards along open-sided walking...

Why it matters: Providing a guard that is only 29 inches high creates a severe fall hazard for occupants in the corridor. This life-safety violation will result in a failed inspection and require the complete redesign and replacement of the balustrade system during construction, causing significant delays and cost impacts.

Suggested next step: Please revise Detail 3/A4.02 to increase the top height of the glass balustrade to a minimum of 42 inches A.F.F. to comply with the guard height requirements of IBC Section 1015.3.

RFI draft: Please revise Detail 3/A4.02 to increase the top height of the glass balustrade to a minimum of 42 inches A.F.F. to comply with the guard height requirements of IBC Section 1015.3.

Summary: The second-floor plan specifies a 'TEMPERED TBK METAL MONOLITHIC GLASS BALUSTRADE' along the corridor edge overlooking the central 'OPEN TO BELOW' area. IBC Section 2407.1 strictly requires that glass used in guards be laminated glass constructed of fully tempered or heat-strengthened glass. Monolithic (single-ply) glass is a direct violation...

Why it matters: Using monolithic glass in a guardrail overlooking an open atrium creates a critical life safety hazard. If shattered, monolithic tempered glass will fall as clusters rather than remaining intact in a frame like laminated glass, posing a severe danger to occupants below. This will result in a failed safety inspection and mandate a costly...

Suggested next step: Please confirm if the glass balustrade specification should be revised from monolithic to laminated tempered glass to comply with the guard material requirements of IBC 2407.1, or provide documentation demonstrating how the open area below is permanently protected from falling glass to satisfy the code exception.

Summary: Detail 2 on sheet A4.33 shows the top of the stair guard wall (identified as '18 GAUGE - BRUSHED STAINLESS STEEL CAP') dimensioned at 2'-10' (34 inches) above the stair tread nosings. This directly violates IBC Section 1015.3, which requires guards to be at least 42 inches high. Furthermore, the 'LET UNDERSIDE-LIT HANDRAIL' is visually depicted...

Why it matters: A guardrail that is significantly shorter than the 42-inch requirement presents a severe fall hazard, particularly on a monumental stair where occupant traffic may be high. Additionally, a handrail mounted below 34 inches impairs graspability and fails to provide adequate support during ascent, descent, or an emergency egress. These...

Suggested next step: Please revise Detail 2/A4.33 to increase the guard wall height so the top of the cap is a minimum of 42 inches above the stair tread nosings, and explicitly dimension the underside-lit handrail to be mounted between 34 and 38 inches above the tread nosings to comply with IBC Sections 1014.2 and 1015.3.

RFI draft: Please revise Detail 2/A4.33 to increase the guard wall height so the top of the cap is a minimum of 42 inches above the stair tread nosings, and explicitly dimension the underside-lit handrail to be mounted between 34 and 38 inches above the tread nosings to comply with IBC Sections 1014.2 and...

Summary: Detail 1 specifies a 'GLASS BALUSTRADE SYSTEM' with an overall dimension of 2'-6' (30 inches) from the finished floor level to the top of the cap rail. IBC Section 1015.3 mandates that required guards must be not less than 42 inches high from the adjacent walking surface. A 30-inch height is a severe deficiency for fall protection along...

Why it matters: Installing a glass balustrade at 30 inches creates a critical life safety and fall hazard. It will fail building inspections, necessitating a complete and costly redesign and replacement of the glass panels and support systems to meet the required 42-inch height.

Suggested next step: Please revise Detail 1 to specify a minimum guard height of 42 inches from the adjacent walking surface to comply with IBC 1015.3, or clarify if this balustrade is exclusively used in a condition where a lower guard is explicitly permitted by code (e.g., specific assembly seating sightlines) and add corresponding notes.

Summary: Details 4 and 5 show the Metal Composite Material (MCM) exterior veneer returning 1'-7' and 1'-8' around the structural steel tie-backs (W14x30 and W21x57). However, the exterior sheathing and weather resistive barrier are only detailed on the main framing face and terminate at the corner. The panel returns are shown with only the MCM panels...

Why it matters: The building code requires a continuous water-resistive barrier behind the exterior veneer to prevent the accumulation of water within the wall assembly. MCM rainscreen systems are designed with open joints and weep holes (as noted in the details) that allow water to enter the cavity. Without a continuous weather barrier wrapping the full...

Suggested next step: Revise details 4 and 5 to show exterior sheathing and a continuous weather resistive barrier wrapping the full extent of the 1'-7' and 1'-8' panel returns to fully enclose and protect the building envelope behind the MCM panels.

Summary: General Note D directs contractors to circuit emergency fixtures so that all lamps can be switched off, with the emergency battery only operating when normal power is interrupted. This configuration allows occupants to turn off all lights using local switches, reducing the means of egress illumination to zero even while the room remains...

Why it matters: IBC Section 1008.2 requires the means of egress to be illuminated at all times a room is occupied, with a minimum level of 1 footcandle (or 0.2 footcandle in assembly areas during performances per Section 1008.2.1). Allowing all egress lighting to be manually switched off without an automatic bypass to maintain minimum illumination violates...

Suggested next step: Please revise General Note D and the lighting control sequence. Emergency egress lighting must either be on un-switched circuits or equipped with a UL 924 automatic load control relay that guarantees the code-required minimum illumination (1 footcandle normally, or 0.2 footcandle during performances) is maintained while the space is occupied,...

RFI draft: Please revise General Note D and the lighting control sequence. Emergency egress lighting must either be on un-switched circuits or equipped with a UL 924 automatic load control relay that guarantees the code-required minimum illumination (1 footcandle normally, or 0.2 footcandle during...

Summary: The plan view of the pocket door/double door assembly shows two equal door leaves, both dimensioned at '2'-7.50'' (31.5 inches) in width. The building code requires that for a door opening with two leaves and no mullion, at least one leaf must provide a minimum clear opening width of 32 inches. A 31.5-inch nominal door leaf cannot physically...

Why it matters: Providing less than 32 inches of clear opening width is a direct violation of means of egress and accessibility requirements. This will cause the doorway to be non-compliant for wheelchair access, leading to failed accessibility inspections and requiring a complete redesign and refabrication of the custom door assembly.

Suggested next step: Please revise the door layout and dimensions to ensure at least one door leaf provides a minimum clear opening width of 32 inches. This typically requires an active leaf dimension of at least 34 to 36 inches depending on the hinge and stop profiles.

Summary: The vertical section for the 'CORRIDOR 219' operable partition states that 'ANY PENETRATION THROUGH HEADER SOUND BAFFLE MUST BE IN ACCORDANCE W/ ASTM E557 AND APPROVED BY PROJECT ACOUSTICIAN.' However, because corridor walls are required to be fire partitions (IBC 708.1), their plenum extensions must comply with IBC Section 714. Section...

Why it matters: Acoustic sealants and standards are designed for sound attenuation, not to test or withstand fire conditions. Following this note will result in trades penetrating the corridor barrier and sealing it with non-fire-rated acoustic caulk. During a fire, these unprotected penetrations will fail rapidly, allowing smoke and fire to breach the...

Suggested next step: Revise the note to require that any penetrations through the header baffle, where it serves as part of a fire-resistance-rated corridor wall, must be protected by an approved penetration firestop system in accordance with IBC Section 714, in addition to meeting acoustic requirements.
