Parameter Budget Method
involves an expanded itemization of construction quantities and furnishings and assignment of unit costs to these quantities.
Matrix
deals with pricing alternatives.
Quantity Take off Method
most precise method for determining budget.
Itemization
Square Footage Method
based on project size and is used before much design work has started.
What are space requirements determined by?
-Functional needs per area
-Size of an object
-Activity planned in the space
-Building code requirements
What is gross area? and the calculation
Floor area construction
GSF = RSF (rentable) + Vertical penetration and building exterior walls
What is rentable area? and the calculation?
Revenue-producing floor area
RSF = USF (Usable) + Prorated share of building common area
What is usable area and the calculation?
Those that are occupiable by tenants
USF = NSF (net) + circulation area
What is net area and what does it include?
Space required for the function in the space or the program area
Includes:
-Individual workspaces
-Dedicated and shared support spaces
-Special mission-critical spaces
What are circulation areas and what types are there?
Primary Circulation = main route connecting the building core and common spaces (public corridors, elevator lobbies, exit stairs, and core toilets)
Secondary circulation = private circulation area that connects to the primary circulation area and public corridors (aisles between individual and support areas)
*Circulation comprises 25%-40% of the total usable area
What is the calculation you use to find circulation area?
NSF x (circulation multiplier - 1) = Circulation Area
What is the calculation to find usable square feet? (USF)
NSF x Circulation Multipler = USF
OR
NSF + circulation area = USF
What is Usable area
Floor area used by the tenant (people and furniture) not shared spaces
Occupant area (always more than the net programmable area)
What is rentable area
floor area tenant pays rent on
Interior area excluding vertical penetrations through the floor (air shafts and elevators)
Includes structural elements like columns and interior/exterior wall thickness
RSF = USF + Prorated share of builing common area
What is the efficiency factor of a single leased space?
the ratio of the net area or net assignable area to the usable area
What are the two types of BOMA calculations?
Method A: Rentable area / usable area for each floor
Method B: Net are / Usable area
When measuring usable area, if more than 50% of the wall is glass, where would you measure from?
the inside surface of the glass to the finish surface (inside face of the tenant side partition
when measuring usable area, if less than 50% of the wall area is glass, where would you measure from?
the exterior walls inside surface to the finished surface (inside face) of the tenants partition
What are all of the occupancy classifications
A: Assembly
B: Business
E: Educational
I: Institutional
M: Mercantile
R: Residential
Storage
Which occupancy classification type is the most restrictive?
Assembly
