Fixture Designations

This note details creation of fixture designations for use in fixtures-takeoff.

Naming

Format

<phase-abbr> - <assembly>(\: <assembly-subtype>)?( \(<comment>\))?( = <fixture-labor>)? <wiring-method> <branch-length>ft

[!example] A - Surface (Pendant) = 2.0hrs - #12 MC+LV 20ft

Order

Use empty designations to separate phases.

[!example]

# Stairwells
BS - Surface = 1.0hrs - #12 EMT 20ft
# Building
## Units - Key
UK - Surface = 1.0hrs - #12 MC+LV 20ft
UK - Surface = 1.5hrs - #12 MC+LV 20ft
UK - Surface (Pendant) = 2.0hrs - #12 MC+LV 20ft
UK - Surface (J-Box For Future Fixture) = 1.0hrs - #12 MC+LV 20ft
UK - Recessed = 1.0hrs - #12 MC+LV 20ft

## Units - Residential
UR - Surface (Tape) = 1.0hrs - #12 MC+LV 25ft
UR - Surface (Wall) = 1.0hrs - #12 MC+LV 25ft

Note

Use lighting control cable assemblies in Amenity areas

Tape Lighting

Also called "cove" or "strip" lighting, however those terms are less specific and potentially confusing.

Use item FIXTURE LABOR 1/2HR and change Fct 1 to match the calculated labor (1 hour per 12 feet).

Note

Tape lighting length is limited by the "max power length" of the model (usually measured in millimeters). Max power length is usually 5000-15000mm (~16-49ft) depending on luminous output and voltage.

A reasonable heuristics is

• 12V strips: 5m (16.4ft)
• 24V strips: 10m (32.8ft)

Separate these fixtures by labor, not length

*** Back of House ***
B - Surface (Tape) = 1.0hr (0-17ft) - MC #12 40ft
_
*** Interior Amenity ***
IA - Surface (Tape) = 1.0hr (00-17ft) - MC+LV #12 40ft
IA - Surface (Tape) = 2.0hr (18-29ft) - MC+LV #12 40ft
IA - Surface (Tape) = 3.0hr (30-41ft) - MC+LV #12 40ft
IA - Surface (Tape) = 4.0hr (42-53ft) - MC+LV #12 40ft
IA - Surface (Tape) = 5.0hr (54-65ft) - MC+LV #12 40ft
IA - Surface (Tape) = 6.0hr (66-77ft) - MC+LV #12 40ft
IA - Surface (Tape) = 7.0hr (78-89ft) - MC+LV #12 40ft

Facade

• Phase = "Facade"

Length and Labor will be more than a normal fixture in BOH/Amenity

Porte Cochere (Drive up Area)

Create its own breakout in WBS, and phase in Accubid

[!quote] This is not technically exposed or drop ceiling, but still use PVC

Site & Courtyard

Important

Coordinate with landscape drawings

Breakdowns
