RFI draft: 📄 G001 Schedule Text: DRAWING INDEX — page 1 --- 📄 P000 Schedule Text: DRAWING INDEX — page 8 --- 📄 E000 Schedule Text: DRAWING INDEX — page 13

Summary: The Enlarged Demolition Plan (Plan 1) explicitly calls for removal of the existing mixing valve that served the CW/HW piping in the area of the emergency eyewash/shower, while the emergency eyewash/shower itself is noted to remain. The corresponding Enlarged Plan (Plan 2) shows new 1' CW/HW piping connections to existing shutoff valves on pipe...

Why it matters: Without a code-compliant ASSE 1071 mixing valve, the emergency eyewash/shower could deliver water at unsafe temperatures during an emergency, creating a serious burn or cold-shock hazard. This would fail plumbing inspection and require procurement, installation, and re-inspection of the mixing valve, causing construction delays and cost...

Suggested next step: Please confirm whether a replacement ASSE 1071 temperature-actuated mixing valve is being provided for the emergency eyewash/shower station that is to remain. If so, show the valve location, piping connections, and specify the valve model on the drawings. If not, revise the design to include an ASSE 1071 mixing valve on the hot and cold water...

RFI draft: Please confirm whether a replacement ASSE 1071 temperature-actuated mixing valve is being provided for the emergency eyewash/shower station that is to remain. If so, show the valve location, piping connections, and specify the valve model on the drawings. If not, revise the design to include an...

Summary: The 'WATER HEATER - GAS TANK' detail shows a check valve installed on the cold water (CW) inlet line feeding the storage water heater. However, the drawing does not show or specify a thermal expansion control device downstream of this check valve, which is a direct violation of code requirements for closed systems.

Why it matters: Because the check valve creates a closed system, heating the 100-gallon capacity water heater will cause thermal expansion that increases system pressure. Without an expansion tank or similar device, this pressure will repeatedly trip the T&P relief valve, leading to premature component failure, potential tank damage, and failure to pass...

Suggested next step: Please revise the water heater detail to include an appropriately sized thermal expansion control device on the cold water line downstream of the check valve, in accordance with code requirements for closed systems.

Summary: The E500 Generator Load Table shows a total load of 119,953 VA, which equates to roughly 333 Amps on a 120/208V 3-phase system. However, the E500 Riser Diagram shows the generator feeding only two Automatic Transfer Switches: ATS-EQDP1 (225A) and ATS-LS1 (40A). Their combined capacity of 265A is significantly lower than the calculated 333A load.

Why it matters: Routing a 333 Amp load through transfer switches rated for only 265 Amps violates NEC sizing rules. This undersized ATS configuration risks catastrophic failure of the emergency distribution system, resulting in loss of power to life-safety and critical medical equipment.

Suggested next step: Please verify the generator load calculations and upsize the transfer switches (e.g., ATS-EQDP1) or redistribute the loads to ensure the combined ATS ratings meet or exceed the total calculated demand of 119,953 VA.

RFI draft: Please verify the generator load calculations and upsize the transfer switches (e.g., ATS-EQDP1) or redistribute the loads to ensure the combined ATS ratings meet or exceed the total calculated demand of 119,953 VA.

Summary: The Door Leaf Legend defines leaf type F1 as a '90MIN F.R. DOOR'. The Door Schedule assigns leaf type F1 to door D100 while also listing its Door Rating as '-' (none) and its hardware as set E4. The specification defines hardware set HW-E4 explicitly as 'NON-RATED' and includes a non-rated exit device (TYPE 1 F03 LESS TRIM). This creates a...

Why it matters: This discrepancy will cause either a failed fire inspection or wasted procurement costs. If the door is truly fire-rated (90 minutes, as indicated by F1), installing non-rated exit hardware would fail code inspection and require complete hardware replacement, causing significant schedule delays and cost overruns. Conversely, if the door does...

Suggested next step: Request the architect clarify the fire rating requirement for door D100. Specifically: (1) Is D100 intended to be a 90-minute fire-rated assembly as the F1 leaf type indicates, or is it non-rated as shown in the Door Rating column and the HW-E4 hardware set? (2) If fire-rated, provide a revised hardware set with UL-listed fire exit hardware per...

(2) If fire-rated, provide a revised...

Summary: Elevation 8 (Dialysis Station Clinical Area - Typical Elevation) explicitly calls out a '3/4' SOLID SURFACE COUNTERTOP W/ 1/4' BEVELED EDGE.' Section 12 36 00 requires solid surface tops to have a 'Finish thickness of top minimum 25 mm (1 inch).' A 3/4' (19 mm) countertop is 6 mm below the specified minimum. Additionally, the plan views on the...

Why it matters: The typical elevation is the detail fabricators will use to dimension and manufacture the solid surface countertops for all dialysis stations. If fabricated at 3/4' thick, the countertops will not meet the specification minimum thickness, requiring costly re-fabrication of all station countertops and significant schedule delay, particularly...

Suggested next step: Request clarification on the solid surface countertop thickness. Elevation 8 shows 3/4' while the plan notes indicate 1' and Section 12 36 00 requires a minimum 25 mm (1 inch) finish thickness. Confirm the countertop shall be 1' thick and that Elevation 8 should be revised accordingly.

RFI draft: Request clarification on the solid surface countertop thickness. Elevation 8 shows 3/4' while the plan notes indicate 1' and Section 12 36 00 requires a minimum 25 mm (1 inch) finish thickness. Confirm the countertop shall be 1' thick and that Elevation 8 should be revised accordingly.

Summary: Detail 3 (Dialysis Station Transaction Top Detail) calls out '1/4' SOLID SURFACE BACKSPLASH'. Section 12 36 00 paragraph 2.10.G.1 requires splash backs to be not less than 19 mm (3/4 inch) thick. The specified 1/4' (6.35 mm) is only one-third of the required minimum thickness.

Why it matters: A 1/4' backsplash is structurally inadequate per the specification and would be fragile and prone to cracking during installation or use. If fabricated at 1/4', the backsplash would need to be removed and replaced with compliant material, causing rework costs and schedule delay. This also affects coordination with any mechanical or electrical...

Suggested next step: Request clarification on the backsplash thickness shown in Detail 3. The drawing calls for 1/4' solid surface backsplash while Section 12 36 00 paragraph 2.10.G.1 requires not less than 19 mm (3/4 inch) thick. Confirm whether the drawing should be revised to show 3/4' minimum backsplash thickness.

Confirm whether the drawing should be revised to show 3/4' minimum backsplash thickness.

Summary: The Finish Schedule specifies INTEGRAL base for rooms with RF1 rubber tile flooring, including Room 100 (Existing Electric Closet) with 'INTERGAL' and Corridor C1-2 with 'INTEGRAL.' RF1 is identified in the Floor Finishes schedule as 'NORA RUBBER TILE DARIVA MUSHROOM 6714' — individual rubber tiles. However, Section 09 65 16 provides integral...

Why it matters: This conflict makes it impossible for the contractor to install the base as scheduled. Individual rubber tiles cannot be turned up walls to form integral cove base. The contractor would be unable to proceed with base installation in the main Corridor C1-2 and Room 100 without clarification, causing a construction delay. If resilient rubber base...

Suggested next step: Request clarification on the base treatment for rooms with RF1 rubber tile flooring (Room 100 and Corridor C1-2). Confirm whether resilient rubber base per Section 09 65 13 should be provided in lieu of integral cove base, or whether the flooring product should be changed from rubber tile to a sheet rubber product capable of forming integral...

Confirm whether resilient rubber base per Section 09 65 13 should be provided in lieu of integral cove base, or whether the flooring product should be changed from rubber tile to a...

Summary: The drawing note describes the complete condensate routing path from WH-1 as: condensate piping passes through an existing opening in a half wall and discharges into a nearby existing floor sink. No acid neutralization kit is shown or noted along this path. The specification requires condensing water heaters (minimum 95% combustion efficiency...

Why it matters: Condensate from condensing water heaters is acidic (typically pH 3-5). While the drawing specifies providing a replacement floor sink liner with an acid-resistant enamel coating for FS-1 to protect the sink itself, discharging untreated acidic condensate can still corrode downstream cast iron drain piping. This omission of the specified...

Suggested next step: Request clarification on the location and specification of the acid neutralization kit required by Section 22 34 00, 3.1.O for the condensing water heaters WH-1. Confirm whether the acid neutralization kit should be installed in the condensate piping between WH-1 and the floor sink FS-1, and request the drawing be revised to show its location,...

Confirm whether the acid neutralization kit should be installed in the condensate piping between WH-1 and the floor sink FS-1, and...

Summary: The WH-1 water heater schedule on drawing P600 explicitly states 'MINIMUM 94% EFFICIENT.' However, Specification Section 22 34 00, Paragraph 2.1.B requires 'a minimum combustion efficiency of 95 percent at operating conditions.' The drawing's 94% minimum is 1% below the specification requirement, meaning a water heater selected to meet the...

Why it matters: A water heater selected at 94% efficiency would fail to meet the project specification and likely would not satisfy ASHRAE 90.1 energy code compliance or ENERGY STAR requirements referenced in the spec. This could result in equipment rejection during submittal review, resubmittal delays, or costly replacement if already procured or installed.

Suggested next step: Request clarification and correction of the WH-1 water heater schedule to reflect the specification requirement of minimum 95% combustion efficiency per Section 22 34 00, Paragraph 2.1.B. Confirm the corrected efficiency value applies to all associated water heater selections.

Summary: Drawing Installation Note 3 specifies mounting all lighting control devices at +42' from floor (centerline dimension). Specification Section 26 27 26 requires wall switches to be installed at 1.2 M (48 inches) above floor and wall dimmers at 1.2 M (48 inches) above floor. This is a 6-inch discrepancy that affects every switch and dimmer...

Why it matters: If switches and dimmers are installed at 42' per the drawing note instead of 48' per the specification, all devices would need to be relocated, requiring patching, repainting, and rewiring. This could cause significant rework costs and schedule delays. Additionally, the specification height of 48' is consistent with ADA accessibility standards,...

Suggested next step: Request clarification on the correct mounting height for lighting control devices (switches and dimmers). The drawing general note specifies +42' AFF while Specification Section 26 27 26 requires 48' (1.2 M) AFF. Which dimension governs?

Summary: Electrical Keyed Note 1 explicitly directs the contractor to 'INSTALL TWIST LOCK RECEPTACLE PROVIDED WITH UNIT WITHIN DISCONNECT ENCLOSURE.' Standard enclosed disconnect switches are not listed or designed to house separate device receptacles. Installing a receptacle inside the enclosure would force operators to open the live electrical...

Why it matters: This configuration violates fundamental electrical safety standards and the equipment's UL listing. It poses a severe shock hazard to facility staff and will fail electrical inspection, causing delays. A separate device box or a specifically listed combination disconnect/receptacle unit is required.

Suggested next step: Please confirm if the twist lock receptacle provided with the BVA booster pump should be installed in a separate, adjacent device box rather than within the disconnect enclosure, or if a factory-assembled combination disconnect and receptacle unit should be utilized instead.

RFI draft: Please confirm if the twist lock receptacle provided with the BVA booster pump should be installed in a separate, adjacent device box rather than within the disconnect enclosure, or if a factory-assembled combination disconnect and receptacle unit should be utilized instead.

Summary: The drawing directs demolition of the entire existing RO water distribution piping system including valving, equipment connections, and all appurtenances, as well as removal of an existing damaged drain pipe to 12 inches below finished floor. However, the asbestos and lead-based paint survey documented in the specification was limited in scope...

Why it matters: The specification states that 'Asbestos surveys are required prior to renovation and demolition activities to satisfy requirements of the USEPA 40 CFR Part 61, Subpart M, the National Emission Standards for Hazardous Air Pollutants (NESHAP) regulation.' Proceeding with demolition of un-surveyed piping (which commonly has asbestos-containing...

Suggested next step: Request clarification on whether additional asbestos and lead-based paint survey/testing is required for the RO water distribution piping, associated valving and appurtenances, and the drain pipe below the finished floor prior to demolition, given these components were explicitly outside the scope of the existing Terracon survey. If additional...

Summary: The drawing Code Notes item A.d. explicitly lists 'NATIONAL ELECTRIC CODE (NFPA 70) 2017 (NEC)' as a primary applicable code. However, Specification Section 26 27 26 (Wiring Devices) references 'NFPA 70-23' which is the 2023 edition of the National Electrical Code. The specification is the governing document and mandates compliance with NEC...

Why it matters: The NEC 2023 contains significant updates over the 2017 edition, including revised GFCI requirements, updated healthcare facility provisions, and new arc-fault protection mandates. If the electrical design and construction follow the 2017 code as stated on the drawing instead of the 2023 edition required by the specification, the installation...

Suggested next step: Request the A/E team to confirm which edition of the National Electrical Code governs this project. The drawing Code Notes reference NEC 2017 (NFPA 70-2017), while Specification Section 26 27 26 references NFPA 70-23 (NEC 2023). Please revise the Code Notes on sheet G002 to align with the specification-required NEC edition, and confirm all...

Summary: The drawing title block indicates the set is issued as '100% WORKING DRAWINGS', meaning it is intended to be a complete, biddable, and buildable set. Demolition Notes 1 and 8 explicitly instruct the contractor to prepare the slab to receive a 'NEW FINISH' and 'NEW SEAMLESS FLOORING'. However, the corresponding Specification Section 09 06 00...

Why it matters: Because the specification finish schedule is completely blank, the contractor cannot determine the required finish materials, manufacturers, colors, or specific application requirements. This prevents accurate pricing and material procurement. Furthermore, different 'seamless flooring' systems (e.g., epoxy vs. latex mastic) require vastly...

Suggested next step: Please provide a fully populated and updated Specification Section 09 06 00 (Schedule for Finishes) that defines all required project finishes, particularly identifying the 'NEW FINISH' and 'NEW SEAMLESS FLOORING' referenced in the demolition plans.
