Events Center 30% Set: 258 Issues Including Critical Fire & Egress Violations

Per IFC Section 1023.2, interior exit stairways must be enclosed with fire barriers having a minimum fire-resistance rating of 1 hour (for buildings under four stories). The 'WALL LEGEND' on Sheet A1.12 defines a specific hatching symbol for a '1HR. FIRE RATED WALL'. However, the walls enclosing 'STAIRS 216' and 'STAIRS 212' are shown using the symbol for a standard 'INTERIOR WALL PARTITION' rather than the required fire-rated hatching symbol.

The exterior stair elevation shows a total vertical rise of 48 inches between the finish floor (0'-0" A.F.F.) and ground level (-4'-0" A.F.F.). The profile graphic depicts exactly 6 risers, which results in a riser height of 8 inches (48 divided by 6). This exceeds the maximum 7-inch riser height allowed by IFC 1011.5.2. Furthermore, the horizontal stair run is dimensioned as 3'-6" (42 inches) for 5 treads, resulting in a tread depth of only 8.4 inches, which violates the minimum requirement of 11 inches.

The drawing specifies a '15' DRIVE (FIRE LANE)' in the northern portion of the site layout. Per Section 503.2.1 of the 2018 International Fire Code, fire apparatus access roads must maintain an unobstructed width of at least 20 feet.

The Erosion Control Plan (C7.01) shows 'PROPOSED STABILIZED CONSTRUCTION ENTRANCE' locations only at the property perimeters (West Uson Ave and North Cage Blvd). Per the graphic scale of 1"=40', the building footprint is located approximately 160 to 240 feet from these stabilized points. IFC 3310.1 requires all-weather vehicle access within 100 feet of FDCs, and IFC 501.4 requires fire apparatus access roads to be installed and serviceable prior to and during construction. The internal drive aisles leading to the 'PROPOSED BUILDING' lack hatching or labels indicating they will be stabilized or maintained as all-weather surfaces during the phase depicted.

The plumbing sewer plan shows elevator sump pumps (ELSP-1, ELSP-2) discharging through an above-ground steel tank separator with piping connecting directly to the 4" sanitary main via fittings and cleanouts. Section 301.6 Exception requires that sumps and sump pumps at elevator shafts be 'indirectly connected to the plumbing system.' Per Section 802.3, an indirect connection requires discharge through an air gap or air break into a waste receptor. The piping shown from the separator to the sanitary system has no air gap, air break, or waste receptor indicated - only direct pipe connections with cleanouts (4"FCO) and a sample port.

According to IPC 404.1 and 404.2, accessible plumbing facilities must be provided in accordance with the IBC and ICC A117.1. In Women's RR 209, the drawing shows a bank of five water closet compartments. Based on the 1/8"=1'-0" scale and the uniform spacing of the partitions, all five stalls appear to be approximately 30 inches wide. No compartment is provided with the 60-inch minimum width required for a wheelchair-accessible stall.

Drawing Detail 10 (24X24 Conc. Col.) specifies (8) #7 longitudinal bars. For a 24-inch square column, the gross cross-sectional area is 576 sq. in. The area of reinforcement provided by eight #7 bars is 4.80 sq. in. (8 x 0.60 sq. in.), resulting in a reinforcement ratio of approximately 0.83%. IBC Section 1901.2 requires structural concrete to be designed in accordance with ACI 318. ACI 318 Section 10.6.1.1 mandates that the area of longitudinal reinforcement for a non-composite compression member shall be at least 0.01 (1%) of the gross area.

The 'Overall Low Roof Framing Plan' (S114) illustrates a comprehensive structural grid (e.g., Grids 1-12 and A-H) and specifies the locations of structural members such as W-shape beams and HSS sections. However, the plan lacks any numerical dimensions for column centers, grid offsets, or building footprint distances. IBC 1603.1 explicitly requires that construction documents show the relative locations of structural members with column centers and offsets dimensioned.

The foundation plan contains multiple notes explicitly stating that the interior grade beam design is not finalized: 'Verifying with geotechnical engineer if interior grade beams will be required. For now assume 12"x30" grade beams at 16 feet on center each direction'. This indicates fundamental uncertainty about whether these structural elements are even required, and if so, what their actual dimensions should be. IBC Section 1603.1 requires construction documents to definitively 'show the size, section and relative locations of structural members.' Showing assumed structural specifications with explicit acknowledgment they are unverified does not satisfy this code requirement.

The drawing shows 'OPEN TO BELOW' multi-story vertical openings (atrium condition) adjacent to Corridor 211. The only separation element shown between the corridor and the open-to-below space is a 'GLASS RAILING' as noted on the plan. Per IBC Section 404.6, atrium spaces shall be separated from adjacent spaces by a 1-hour fire barrier or a glass wall forming a smoke partition with specific sprinkler protection. A glass railing is neither a 1-hour fire barrier nor a full-height glass wall smoke partition - it is simply a guard rail typically 42 inches high that cannot contain fire or smoke spread between floors.
