Missing Structural Oil Pit in Hydro Vault 118
Architectural
The Architectural Floor Plan (A2.03) explicitly details an 'OIL PIT' with electrical grating in Hydro Vault 118, including dimensions for the pit. However, the corresponding location on the Structural Slab Edge Plan (A2.63) shows a continuous slab surface with a 'LINE OF HYDRO DUCT BELOW SLAB' and does not provide the required slab depression,...
Missing Garbage Chute on Penthouse Floor Plan vs. Slab Edge Plan
Architectural
Drawing A2.72 (Penthouse Level - Slab Edge Plan) specifies a 'GARBAGE CHUTE SLAB OPENING' in the central core area. Additionally, drawing A2.32 (Level 15 - Reflected Ceiling Plan) shows 'GARB. CHUTE 1504' directly below this location. However, drawing A2.12 (Floor Plan - Penthouse Level) fails to show a garbage chute or enclosing shaft walls in...
Inconsistent Architectural Layout for Main Electrical Room and Hydro Vault
Electrical
The Ground Floor Power Plan (E-353) and the Enlarged Plan View (1/E-600) use conflicting architectural layouts for the primary electrical spaces between grids H and L. The Enlarged Plan (E-600) shows the Hydro Vault extending from grid H to grid K, with 'ELECTRICAL ROOM 11' (housing main equipment like SWBD6-1) located between grids K and L....
Contradicting Specifications for Lighting Fixture L38
Electrical
The 'LUMINAIRE SCHEDULE' on the site plan (E-151) defines fixture L38 as an exterior 3.9W FX Luminaire. Conversely, the 'LIGHTING FIXTURE SCHEDULE' on E-900 defines L38 as an interior 40/50/60W Magic Light fixture for the Ground Floor Amenity. Both E-151 and E-253 floor plans use the 'L38' tag for these completely different applications.
Conflicting Function for Room 105 (LAN Room vs. Dog Wash / Suite)
General
The Security Core Riser diagram states that the main network distribution hub is 'LAN ROOM [0105]' on the Ground Floor. However, the Ground Floor ICAT Plan contradicts this by assigning Room 105 to a 'DOG WASH' and a residential 'SUITE'. No LAN Room is shown on the floor plan.

Spatial and Grid Layout Conflict for Suite 709 (2BED BF - 2H-BF)ArchitecturalCritical
Summary: The Level 7-9 floor plan (T-459) designates Suite 709 as '2BED BF - 2H-BF' and locates it between horizontal grids 9 and 12, with a demising wall at grid 9 separating it from Suite 708. However, the corresponding typical unit plan for '2BED BF - 2H-BF' (T-474, Detail 4) shows a footprint that extends above grid 9 down to grid 12. Specifically,...

MUA-1 Gas Heating Leaving Air Temperature DiscrepancyMechanicalCritical
Summary: The 'DDC SEQUENCE OF OPERATION' on M-709 dictates that the MUA-1 gas burner will fire to 'MAINTAIN THE SUPPLY AIR SETPOINT, ADJUSTABLE, INITIAL SETPOINT OF 80°F'. Conversely, the 'MAKE-UP AIR UNIT - GAS HEATING SCHEDULE' on M-900 indicates a design Leaving Air Temperature ('L.A.T. D.B. (°C)') of '9.2' (48.6°F).

Uncoordinated Equipment Layout and Incomplete Enlarged Plan for Water Supply RoomMechanicalCritical
Summary: The Water Supply Room (P1-02) located between Grids A-C and 10-12 contains a spatial clash and cross-reference mismatch. The Fire Protection plan (M-552) locates the 'FIRE PUMP SKID' (JP-1, FP-1) and PRV Station in the exact same footprint where the Plumbing plan (M-253) locates incoming water lines and backflow preventers ('BP-1A', 'BP-1B',...

The Enlarged Penthouse Mechanical Room plan (M-600 Detail 1) aligns with the upward routing but specifies...
