Summary: The Water Calculation Worksheet designs the water distribution system for a minimum pressure of 8.00 psi at the controlling fixture (Water Closet). However, the Fixture Schedule specifies the primary water closet (PF-WC-1HL) utilizes a Sloan Flushmate pressure assist device, and the alternate water closet (PF-WC ALT) is a flush valve type. Note 11 correctly acknowledges that direct supply flush...

Why it matters: Sizing the water distribution system based on an inadequate 8 psi requirement at the controlling fixture will lead to undersized piping. Pressure-assist tanks and flush valves require significantly higher dynamic pressure (typically 20-25 psi minimum) to properly complete a flush cycle. Without a...

Suggested next step: Please revise the Water Calculation Worksheet to reflect the minimum operating pressure required by the specified pressure-assist or flush-valve water closets (e.g., 20-25 psi). Upsize the water distribution piping and incoming water service as necessary to ensure adequate dyn...

Summary: The Water Calculation Worksheet sizes the water distribution system using a minimum flow pressure of 8.00 psi at the controlling fixture (a water closet), and General Note 11 explicitly specifies minimum acceptable pressures of 25 psi for flush valves and 8 psi for all other outlets. However, the plumbing fixture schedule specifies a pressure-assist tank water closet (PF-WC-1HL/HR) and an alter...

Why it matters: Designing the water distribution system to an 8 psi or 25 psi minimum pressure directly violates the building code minimums and drastically overstates the allowable friction loss. If installed according to these calculations, the piping will be significantly undersized, causing the scheduled pres...

Suggested next step: Please revise the water calculation worksheet to reflect the code-required minimum flow pressure of 20 psi for the scheduled pressure-assist tank water closets (or 35 psi if the alternate flush valve water closets are selected). Recalculate the allowable pressure loss, upsize ...

Summary: The plumbing plan shows primary roof drain connections ('4" UP TO RD') and secondary/overflow roof drain connections ('4" UP TO ORD') combining into the same '4" STM' pipe. This violates the code requirement that secondary roof drain systems must have an end point of discharge separate from the primary system.

Why it matters: Connecting the overflow drains to the primary storm drainage system defeats their purpose. If the primary system becomes clogged, the secondary system will also fail to drain, which can lead to severe water ponding, exceeding the structural load capacity of the roof, and potentially causing a str...

Suggested next step: Please revise the storm drainage design to provide completely independent piping and discharge points for all secondary (emergency) roof drains, separating them from the primary storm drainage system as required by code.

Summary: The Foundation Plan (S2.0) details a '7' - 11 1/2"' building protrusion on the northeast corner, noted as a 'STUD BEARING WALL. SEE OTHER PLANS.' Conversely, the Landscape Plan (L1.0) depicts the 'CHASE BANK PROPOSED BUILDING' with a straight eastern footprint, leaving a parallel space for the 'DRIVE THRU UP ATM ONLY' lane. The structural footprint's nearly 8-foot eastward protrusion conflicts ...

Why it matters: A major discrepancy in the building footprint on the drive-thru side will lead to severe layout failures. If the building protrudes almost 8 feet further east than the site plan accounts for, the drive-thru lane, curbs, and clearances will not fit within the site geometry.

Suggested next step: Please reconcile the building footprint between the Foundation Plan and the Landscape/Site Plans. Verify if the 7'-11 1/2" stud bearing wall protrusion on the northeast corner is required and update the Landscape Plan's drive-thru lane and paving layouts to accommodate it with...

Summary: The architectural floor plan shows the West exterior wall extending continuously outward past Grid B at the Northwest corner, enclosing the western portion of 'PCS. 2 OFFICE 104'. Conversely, the structural framing plan shows the main exterior wall framing and window headers ('OP4') stepping inwards to align directly on Grid B in this same area.

Why it matters: If the structural framing is constructed along Grid B as indicated on the structural plan, there will be no structural support or headers for the Northwest architectural footprint shown on the floor plan. This indicates a major footprint discrepancy that requires coordination to determine the cor...

Suggested next step: Please clarify the correct building footprint at the Northwest corner. Should the structural framing extend outwards to support the West exterior wall shown outboard of Grid B on the architectural plans, or should the architectural floor plan be revised to step the building in...

Summary: The Mechanical Roof Plan (M2.3) places condensing units (CU-1, CU-2) and fresh/exhaust air goosenecks between grid lines H and J. Keynote 1 on M2.3 requires 'REFRIGERATION LINES DOWN THROUGH ROOF' for the condensing units, and the goosenecks inherently require roof penetrations. However, the Architectural Roof Plan (A1.3.1) designates the area between grid lines H and J with keynote R-22, which...

Why it matters: Allowing roof penetrations over a data room introduces severe risks of water infiltration and damage to sensitive electronic equipment, violating architectural requirements. Resolving this conflict will likely require relocating the mechanical units and goosenecks to a permissible roof area, whic...

Suggested next step: Please clarify the permitted location for mechanical condensing units CU-1/CU-2 and the fresh/exhaust air goosenecks. M2.3 requires roof penetrations for these units between grids H and J, but A1.3.1 (Keynote R-22) designates this exact space as a Data Room with 'NO THROUGH RO...

Summary: Mechanical Detail 9 on M4.1 indicates that the piping roof curb should be mounted on an "EXISTING CONCRETE DECK". Conversely, the Structural drawings on S1.1 detail the roof substrate as a corrugated metal deck supported by a "JOIST OR BEAM", specifying a reinforcement sheet to be "FASTENED TO EACH FLUTE".

Why it matters: A discrepancy in the primary roof deck material profoundly affects the method of fastening, required structural reinforcement, and roof curb procurement (curbs designed for flat concrete decks differ from those designed for fluted metal decks). If the roof is actually a metal deck, the mechanical...

Suggested next step: Please clarify the existing roof deck composition. Is the roof substrate an existing concrete deck as indicated in the mechanical piping curb detail, or a corrugated metal deck supported by joists as shown in the structural roof opening details?

Summary: The Electrical Mechanical Equipment Schedule designates the Electric Duct Heater (EDH-1) as a 3-phase unit (208V-3Ø) powered via a 3-pole breaker (20A-3P). However, the schedule specifies a 2-pole local disconnect switch (30AS-2P, NF). Electrical Equipment General Note 1 requires disconnect switches to be installed in accordance with local code requirements.

Why it matters: Using a 2-pole disconnect switch on a 3-phase circuit is a clear mistake and a serious electrical code violation. When the switch is in the 'off' position, it will fail to disconnect one of the energized phases, leaving the equipment partially live and creating a severe shock hazard for maintenan...

Suggested next step: Please confirm if the EDH-1 local disconnect switch should be revised from '30AS-2P, NF' to a 3-pole switch (e.g., '30AS-3P, NF') to properly disconnect all ungrounded conductors for the 208V-3Ø power feed in accordance with local code requirements.

RFI draft: Please confirm if the EDH-1 local disconnect switch should be revised from '30AS-2P, NF' to a 3-pole switch (e.g., '30AS-3P, NF') to properly disconnect all ungrounded conductors for the 208V-3Ø power feed in accordance with local code requirements.

Summary: The ELECTRICAL MECHANICAL EQUIPMENT SCHEDULE specifies the Electric Duct Heater (EDH-1) as a 3-phase unit operating at "208V-3Ø" and powered via a 3-pole breaker ("20A-3P"). However, the local disconnect switch is specified as a 2-pole switch ("30AS-2P, NF"). A 3-phase circuit contains three ungrounded conductors and requires a 3-pole disconnect switch to safely disconnect all ungrounded power ...

Why it matters: Installing a 2-pole disconnect switch on a 3-phase piece of equipment is an electrical safety violation and will fail inspection. It prevents proper termination of all conductors and creates a severe shock hazard. This mistake will require a change order to procure and install the appropriately s...

Suggested next step: Please confirm if the local disconnect switch for the EDH-1 Electric Duct Heater should be revised from a 2-pole switch (30AS-2P) to a 3-pole switch (30AS-3P) to properly accommodate the 208V-3Ø power feed.

RFI draft: Please confirm if the local disconnect switch for the EDH-1 Electric Duct Heater should be revised from a 2-pole switch (30AS-2P) to a 3-pole switch (30AS-3P) to properly accommodate the 208V-3Ø power feed.

Summary: The Floor Plan (A1.1.1) calls out details 4/A5.1.5 and 12/A5.1.5 for the exterior pier corners. However, both of these details contain unresolved redline markups stating 'COLUMN IN WRONG PLACE' and direct attention to the structural drawings for the column center line. This indicates a direct, unresolved contradiction between the architectural pier layout and the structural column placement.

Why it matters: Since this drawing set is marked as Issued For Construction (IFC), an unresolved column location conflict will halt construction at the foundation/steel erection phase. The structural steel and architectural envelope (storefront and fiber cement panels) cannot be properly detailed, fabricated, or...

Suggested next step: Please confirm the correct column center line and grid intersections for the exterior piers referenced in details 4/A5.1.5 and 12/A5.1.5. Clarify if the structural steel or the architectural exterior envelope needs to be adjusted to resolve the 'COLUMN IN WRONG PLACE' conflict.

Summary: The Floor Plan (A1.1.1) depicts the East exterior wall (along grids H and J, enclosing the Data Rm, Equip Rm, and Restrooms) as a continuous solid wall with no exterior doors, ATMs, or canopies. However, the East Elevation (2/A2.2) contradicts this by showing multiple exterior doors (including double doors), an ATM (referenced as 'EE-35 BANK EQUIPMENT'), and an entrance canopy. The floor plan e...

Why it matters: This represents a major coordination failure affecting structural framing, exterior envelope, electrical, and security. Construction cannot proceed if major penetrations (doors, ATM) shown in the elevations do not exist in the floor plan layout.

Suggested next step: Please clarify the intended design for the East exterior elevation. Should the doors, ATM, and canopy shown on 2/A2.2 be added to the floor plan, or is the East Elevation drawing incorrect and needs to be revised to reflect the solid wall shown on A1.1.1?

RFI draft: Please clarify the intended design for the East exterior elevation. Should the doors, ATM, and canopy shown on 2/A2.2 be added to the floor plan, or is the East Elevation drawing incorrect and needs to be revised to reflect the solid wall shown on...

Summary: The horizontal grid line labels and their corresponding spacing dimensions contradict each other between the intermediate framing plan (S2.1) and the roof framing plan (S2.2). S2.1 indicates a 3'-9 3/8" gap between Grids 1 and 2, and a 2'-4 3/4" gap between Grids 7 and 8. However, S2.2 applies the 3'-9 3/8" gap between Grids 1 and 3, applies a 9'-3 3/4" gap between Grids 3 and 4, and specifies ...

Why it matters: This misalignment in grid numbering and dimensional spacing is a critical coordination failure. If the grid lines are not uniformly identified and dimensioned across all structural levels, it will cause catastrophic layout errors during foundation placement, framing erection, and architectural al...

Suggested next step: Please review the horizontal grid line numbering and dimensions along the west wall. Clarify the correct grid sequence and spacing, and update S2.1, S2.2, and all associated plans to be consistent.

RFI draft: Please review the horizontal grid line numbering and dimensions along the west wall. Clarify the correct grid sequence and spacing, and update S2.1, S2.2, and all associated plans to be consistent.

Summary: The Entrance/ATM canopy is designed with a flat soffit and a 12-inch fascia (Note EE-07), creating a perimeter that extends above the roof and will entrap water. Note EE-11 describes a combined "DOWNSPOUT/OVERFLOW" for the canopy, and elevation drawings show only a single vertical pipe descending from the canopy. Section 1502.2 of the IBC requires a separate secondary (emergency overflow) roof ...

Why it matters: Without an independent secondary drainage path, a blockage in the downspout or the subsurface cast iron drain hub (as described in Note EE-11) would cause up to 12 inches of water to pool on the flat canopy roof. This accumulation adds a severe, unintended live load that could lead to a catastrop...

Suggested next step: Please revise the canopy drainage design to include an independent secondary (emergency overflow) roof drain or scupper, as required by IBC Section 1502.2. If the single primary downspout clogs, an independent system must be present to prevent water entrapment.
