Charlotte South End Hotel Spec Interpretation

Spec interpretation notes for charlotte-south-end-hotel with clarification by joel-jansen:

EMT Fittings

[!quote] Spec 260510 2.4(E) EMT - Electrical metallic tubing, "thin wall" zinc coated steel, enameled interior, ANSI C80.3, UL-797, assembled using concrete tight and rain tight gland-ring compression threaded type fittings except where alternate type fittings are allowable by the NEC and authorities have jusrisdiction [sic].

[!quote] Spec 260510 2.4(N)(2) EMT connectors - Provide gland ring compression threaded fittings, except-

a. Concrete tight double set screw type connectors are acceptable in 2 1/2-inch and larger sizes in dry locations only.

[!quote] Joel Jansen 2026-03-10 (pp.) Takeoff as specified

Liquid-Tight Conduit

[!quote] Spec 260510 2.4(G) Liquid-tight flexible metallic raceway shall be similar to standard flexible steel conduit except encased in liquid tight neoprene outer jacket.

No definition is provided for a liquid-tight flexible non-metallic raceway

[!quote] Spec 260510 2.4(G)(7) (text decoration added) Provide liquid-tight flexible conduit for each motor and rotating device for power and control, ~~computer room~~¹ and for other equipment requiring adjustments or removal for service in mechanical rooms or where subject to moisture or weather.

[!quote] Joel Jansen 2026-03-10 (pp.) Assume LFMC.

Voltage Drop

[!quote] Spec 260510 2.2(C)(4) (text decoration added) Sizing of conductors and conduits shall be solely the responsibility of the Contractor and shall be based on the NEC, nfpa-70_310_conductors_for_general_wiring. Ampacity shall be equal to, or greater than, the required load specified. ==Voltage drop shall be no greater than that allowed by the NEC.==

[!quote] Dwg. E00-00 "GENERAL PRICING NOTES" Note 9 PROVIDE ALLOWANCE TO UPSIZE FEEDERS/BRANCH CIRCUITS (OVER 100 FEET FOR 120/208V, OVER 200 FEET FOR 277/480V) FOR A MAXIMUM OF 3% VOLTAGE DROP.

Lighting Control

Corridors

Corridors may or may not have included digital control

[!quote] LEED Checklist, item "Interior Lighting" (Project Manual p. 23) Option 1: Lighting Control: Provide adjustable lighting controls for 90% of individual occupant spaces with at least 3 lighting levels or scenes (on, off, mid-level). Provide control for all shared multi-occupant spaces.

Checklist assumes this point.

[!quote] Typical Unit Corridor Occupancy Sensor Callout (Ref dwg. E03-06 thru E03-14) OCCUPANCY SENSORS TO DIM CORRIDOR LTG TO 50% WHEN NO OCCUPANCY

[!quote] Dwg. E06-01 "LIGHTING CONTROL NARRATIVE" SPACE TYPE Corridor is shown only with captive key card control

Units

[!quote] LD03-XX Typical Master Switch Callout MASTER - TO CONTROL ENTRY AND ROOM ONLY. ELECTRICAL ENGINEER TO SPECIFY ENERGY CODE COMPLIANT “MASTER OFF” FOR THE REQUIRED GUESTROOM LOADS. GMLD RECOMMENDS LUTRON’S "CODE-SMART" SYSTEM ...

Lighting control quote does not include master switches

[!quote] PDR Lutron Lighting Control Quote 2025-12-10 (13) Pre-Assembled Processor Panel, (14) Athena Centralized Din Lighting Control Panel, (14) DALI ESN Panel, (14) QS Sensor Module, (4) Touchscreen, (112) QS Wired Keypads, (2) Partition Sensor, (31) Wired Occupancy Sensor, (2) 5 Contact Closure Inputs and 5 Relay Outputs

These are captured as a budget

[!quote] 2025.12.09 - Charlotte South End Hotel - Bid Sheet v16-4-2, "Add-On Items" master switch in guestrooms - TBD | $ 72,023

[!quote] Proposal 2025-12-12, Pricing Summary Lighting Controls – Lutron (turnkey) $ 850,000

Assuming that this line includes master switches based on sum of quote and switch allowance

[!quote] PDR Lutron Lighting Control Quote 2025-12-10, Pricing Summary –Turnkey Lighting Control: Lutron $ 738,400.00

EV Chargers

[!quote] Proposal 2025-12-12, Alternates Add: (21) EV-Capable and (3) EV-Installed per Building Connected $ 38,000

Panel LG's schedule (E06-13) shows (10) 40A/2P circuits with description "EV CHARGER".

These circuits are not shown on the electrical set, nor are any chargers besides.

I feel fairly confident this is erroneous. ↩︎
