Military Facility: 346 Issues Found in Pre-Permit Review

The panel schedule on E-606 shows Inverter INV-A with Location: ELEC 107, while the one-line power diagram on E-701 shows the Emergency Source Lighting Inverter INV-A in ROOM 103. These are two different rooms, creating a direct contradiction about where this life-safety emergency lighting equipment should be installed.

E-121 General Note 1 specifies that all luminaires and lighting devices are served from Panel 1LOL1 at 120V, while E-402 General Note 1 specifies the same panel serves luminaires at 277V. Since E-121 references the enlarged plans on E-402 for lighting details, both sheets apply to the same sleeping room and bathroom areas, creating a direct contradiction in the voltage specification for the same lighting circuits.

The door and hardware schedule on sheet A-601 lists L6/A-611 in the HEAD column for multiple 2'-6" wide interior doors. However, detail L6 on sheet A-611 is titled 'EXT - WINDOW SILL DETAIL' which is an exterior sliding window sill condition, not an interior door frame head detail. This is a direct cross-reference mismatch.

The Architectural Finishes Schedule specifies GYP-2 (Water-Resistant Gypsum Board Ceiling) to be installed in shower areas. The Room Finish Schedule shows GYP-2 ceiling for all TOILET/SHOWER rooms. IBC Section 2509.2 requires ceiling panels in shower areas to be materials listed in Table 2509.2, which includes only glass mat gypsum backing panel, fiber-cement backer board, or fiber-mat reinforced cementitious backer unit. Water-resistant gypsum board is not one of these approved materials.

Code: 2021 International Building Code

General Note 4 on the drawing specifies 'PROVIDE WATER RESISTANT GYPSUM WALLBOARD AT ALL WET AREAS AND/OR AREAS TO RECEIVE WALL TILE.' The enlarged plans show toilet/shower rooms with wall tile indicated. IBC Section 2509.2 explicitly requires that materials used as a base for wall tile in tub and shower areas shall be of materials listed in Table 2509.2. Water-resistant gypsum wallboard is NOT listed in Table 2509.2.

Code: 2021 International Building Code

The drawing explicitly claims the project is exempt from accessibility requirements, stating 'This project is exempt from accessibility requirements. This facility will be accessed and used by only able-bodied personnel.' However, IBC Section 1103.1 requires that all buildings 'shall be accessible to individuals with disabilities.' The exceptions listed in Section 1103.2 are limited to specific building types. The stated basis for exemption—that users will be 'able-bodied personnel'—is not among the recognized IBC exceptions.

Code: 2021 International Building Code

General Note 10 on sheet S-101 explicitly states that foundations are preliminary and footing sizes are provided for general pricing only, with final sizes, quantities, and locations subject to review of metal building system submittal. The plan is also titled 'PRELIMINARY FOUNDATION PLAN.' This conflicts with IBC Section 1603.1 which requires construction documents to show the size, section and relative locations of structural members.

Code: 2021 International Building Code

The power floor plan E-101 shows ACC-U-5 assigned to Panel 1HOL1 circuits 4,6. However, the panel schedule E-604 shows ACCU-5 on Panel 1HOM1 circuit 19 as a 3-pole, 40A load. Panel 1HOL1 is a 120/208V Wye system while Panel 1HOM1 is a 480/277V Wye system. This represents both a panel assignment conflict and a voltage system conflict.

The Grading and Drainage Plan (CG101) specifies 38 LF of 18" RCP - CLASS III at 0.50% slope for Storm Drain Line A, while the Storm Drain 'A' Profile (CG201) shows 188 LF of 18" RCP - CLASS III at 0.50% slope for the segment from MH-02 to the existing catch basin connection. This is a 150 LF difference (nearly 5x the plan quantity) for the same pipe run.

Drawing E-602's Equipment Schedule lists ACCU-6 as a 480V, 3-Phase unit with a 40A MOCP and references Keyed Note 4. Keyed Note 4 explicitly specifies '2#12, 1#12G' (suitable for 20A single-phase), which is severely undersized for a 40A load and has incorrect phase count. This conflicts with the E-701 Branch Circuit & Feeder Schedule, which specifies '3 - # 8' conductors for a 40A circuit.

Sheet A-414 references A-006 for accessibility standards. A-006 depicts required rear and side grab bars for Water Closets. However, the Typical Toilet/Shower Elevation (J6) on A-414 shows a Towel Bar (TB2) installed directly above the toilet in the zone typically reserved for the rear grab bar (33"-36" AFF). No grab bars are shown in the elevation despite the reference to accessibility diagrams.

Wall Sections B17 and B14 on sheet A-311 depict a window opening condition sitting on a masonry base with the note "2'-8" T.O. CMU" and a vertical opening dimension of "2'-4"". These sections explicitly reference "PER WINDOW TYPE RE: A-601". However, Window Types 1, 2, and 3 detailed on sheet A-601 are all shown as "7'-0"" tall assemblies referenced directly from "FIRST FLOOR 100'-0"", which implies a floor-level sill rather than a partial-height window on a 2'-8" raised CMU sill.

There is a direct contradiction in the structural grid orientation between two North Elevation details on sheet A-201. Detail M10 (Overall North Elevation) displays the vertical grid lines ordered Left-to-Right from AA to JJ. Conversely, Detail J10 (New Addition - North Elevation) displays the grid lines in reverse order, Left-to-Right from JJ to AA.

The Utility Plan (CU101) bears a State of California professional engineer seal, while the Underground Drain and Vent Plan (P-100) bears a State of Wisconsin professional engineer seal. This creates a direct conflict regarding the project's legal jurisdiction and location.

The drawing specifies 'SIPR SURFACE MOUNTED RACEWAY' running in the corridor and serving outlets within adjacent rooms. In Group R occupancies, corridor walls are required to be fire-resistance rated (Section 1020.1). Surface mounted raceway systems cannot penetrate fire-resistance-rated walls continuously while maintaining the required rating.

Code: 2021 International Building Code

Detail G14 explicitly states in Note 1 that "THIS METHOD OF INSTALLATION IS REQUIRED IN AREAS WITH INACCESSIBLE CEILING." However, the detail depicts the conduit extending vertically and terminating "WITHIN 12" OF CABLE TRAY" in the space above the ceiling line. If the ceiling is inaccessible (e.g., hard drywall/gypsum), the termination point of the conduit in the interstitial space is physically inaccessible.

Code: 2021 International Building Code

The drawing specifies that all luminaires are 277V (General Note 1), including those in the 'SLEEPING ROOM' spaces. However, IBC Section 2701.1 adopts NFPA 70 (NEC), and NEC 210.6(A) explicitly prohibits luminaires exceeding 120V nominal in dwelling units, guest rooms, and sleeping units.

Code: 2021 International Building Code

Panel 1POL2 supplies 120V circuits to "SLEEPING ROOM" locations (Circuits 1-20). The panel schedule specifies standard 20A breakers and the legend does not include an indicator for Arc-Fault Circuit Interrupter (AFCI) protection. NFPA 70 (referenced by IBC 2701.1) mandates AFCI protection for branch circuits supplying outlets in sleeping units/guest rooms.

Code: 2021 International Building Code

IBC 1008.3.3 requires generator rooms to be automatically illuminated by the emergency electrical system in the event of a power failure. Panel 1POL1 supplies "GENERATOR LIGHTS AND RECEPTS" (Circuit 33) but also supplies non-essential, optional loads such as "DRYER" (Circuits 5, 9) and "DISHWASHER" (Circuit 8). The presence of these optional appliances indicates that Panel 1POL1 is a Normal or Standby panel, not a segregated Emergency (Life Safety) panel.

Code: 2021 International Building Code

Panel 1HOL2 serves 'Heat' loads (VAV-1 through VAV-21), which are defined as continuous loads by the electrical code. Continuous loads require a 125% demand factor for sizing feeders and overcurrent protection. The panel schedule applies a demand factor of only 102.98%, resulting in a 'Total Design Current' of 60 A. The correct design current should be approximately 73 A (58 A × 1.25).

Code: 2021 International Building Code

Detail E14 mandates the installation of "MANUFACTURED RADIUS DROPOUTS" on both sides of the cable tray wall penetration. The detail shows these accessories installed directly at the face of the "RATED WALL", within or immediately adjacent to the through-penetration firestop system. Standard UL/listed firestop systems for cable trays are tested with the tray itself and specific fill materials. They do not list or approve the inclusion of auxiliary plastic or metal radius dropout accessories within the seal interface.

Code: 2021 International Building Code

IBC 1008.3.3 requires that electrical equipment rooms be 'automatically' illuminated in the event of power supply failure. The Lighting Control Schedule specifies 'MANUAL ON CONTROL' for Electrical & Mechanical Rooms (MEP) and explicitly states 'NO UL924 RELAY REQUIRED' (UL924 | N). Without a UL924 bypass relay, if the manual switch is in the 'OFF' position during a power outage, the lighting will not turn on automatically.

Code: 2021 International Building Code

The drawing sheet includes a Professional Engineer stamp for the "STATE OF CALIFORNIA", a region with significant seismic design requirements. The AHU Schedule lists AHU-1 as a rooftop unit with a "WEIGHT WITH CURB" of 2,094 lbs. The schedule's Legend explicitly offers "9 SEISMIC ROOF CURB" as an option. However, the Accessories selected for AHU-1 do not include Accessory 9 (Seismic Roof Curb).

Code: 2021 International Building Code

Panel 1HOM1 lists circuit 13/15/17 "AHU-1 HEAT" with a 50 A trip breaker. The Load Classification summary indicates the total connected Heat load is 39,000 VA. At 480V 3-phase, 39,000 VA draws approximately 46.9 Amps. Per IBC 2701.1, which adopts NFPA 70 (NEC), fixed electric space heating is a continuous load and overcurrent protection must be sized at 125% of the load (46.9 A x 1.25 = 58.6 A). The provided 50 A breaker is undersized.

Code: 2021 International Building Code

The drawing specifies a 'Manual Transfer Switch' (Note 9.127) equipped with 'Generator Camlocks' (implying a portable generator connection). However, Note 9.124 indicates this system serves 'Fire Protection / Life Safety Equipment'. Code requirements for Emergency and Standby Power Systems (IBC 2702.1.4) mandate that power be provided 'automatically' within 10 seconds for emergency loads and 60 seconds for standby loads.
