## 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.

[^1]: I feel fairly confident this is erroneous.

### 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|Article 310]].
> 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.
