Why Measure?
The Three Most Important
Things in Real Estate?
1. Location 2. Location
3. Square Footage
With apologies to William Zeckindorf, you can have the best location in the world, but if you have no square footage, you have nothing!
Square footage is the
currency of real estate
.Why Measure?
Square Footage = Value
Three Basic Appraisal
Methods for Property
Value:
1. Revenue Stream: NPV of ($/RSF X RSF) 2. Comparable sales: $/GSF X GSF 3. Replacement Cost: $/GSF X GSFWhy Measure?
> Due Diligence:
If buyers due diligence measurement shows more RSF, you have left money on the table. It buyers due diligence
measurement shows less RSF, your sales
negotiation may be challenging!

10 New Concepts in BOMA-10
1. External circulation
2. Enclosure
3. Enclosure limit
4. Property line
5. Vault space (disclosure)
6. Connectors (disclosure)
7. Restricted headroom (disclosure)
8. Mezzanine (disclosure)
9. Occupant storage
10.Capped rentable area
1 - External Circulation
<ILLUSTRATION 6>
2 - Enclosure
> Separation between “inside” & “outside”
Determines IGA boundary
> Appropriate to local climate
Climate: In warm climates, the degree of enclosure necessary for habitation is less than in temperate or cold climates:
Puerto Rico St. Thomas Palm Springs, AZ.
> Appropriate to occupancy
Some space do not require “room temperature” Loading Docks
Mechanical floors Structured parking
3 - Enclosure Limit
> @ PP Thoroughfare
Colonnades
> Right to enclose
Actual enclosure irrelevant
Defines IGA Boundary
+ Occupant areas
+ Service areas
> Established by
Lease or agreement
Statutory constraint
Building feature
4 - Property Line
> Legal Boundary
Parcel of land
> If within building,
it is an IGA
Boundary
Exception: Vault Space
> Connectors

8 - Mezzanines
> Between floors
> Limited size
1/3 area of floor below
Include in area of floor
below
> Three Types
Temporary
(Don’t measure)
Permanent
(Always measure)
Unclassified
9 - Occupant storage
> Not on occupant
floor level
Basement / parking
Mechanical floor
> Unsuitable for
office use
Low Lighting/Power
No Finishes
No HVAC
> Lease as storage
Usable basis (no load)
Account for separately
10 - Capped Rentable Area
> Method of dealing with a high load factor
Consistent method – preserves true rentable area Do not “leave out” any areas to reduce load factor Lost area permanently reduces property value.
> Three steps
1. Establish Market Load Factor
2. Establish Capped Load Factor by floor:
If Actual LF > Market LF, use Market Load Factor If Market LF > Actual LF, use Actual Load Factor 3. Capped Rentable Area = Occupant Area X Capped Load
Factor
> Market Load Factor set by building ownership
Analyze competitive properties in local market Decision is sole discretion of building ownership Will result in loss of rentable area
BOMA-10 v BOMA-96
> Total rentable area generally same as BOMA-96
External circulation may increase rentable area in some buildings
> Rentable area of tenants more stable over time.
> Building service areas include full wall thickness
Small reduction in occupant area & increase load factors
> Occupant storage areas separate from RSF
> Capability to cap rentable area if needed
> Major vertical penetration criteria
1 square foot (0.1 square meter)
> Disclosed four kinds of space
> Enclosure limits (other than building line)
> Parking measured
> Optional Method B – Single Load Factor
Why switch from
BOMA-96 to BOMA 2010?
> Lower likelihood of square footage disputes
More and better illustrations More defined terms with discussion
Clearer methodology – charts & spreadsheets No separate Q&A document, fewer ambiguities
> New features
Increased stability of rentable areas External circulation ($)
Tenant storage
Why not switch from
BOMA-96 to BOMA-10?
> Tenant rentable areas will change
Total rentable area of most buildings will not change
Rentable areas of individual floors & tenants will vary up & down
> New concepts may be unfamiliar to tenants &
consultants.

Why
10 drivers of change 14 new terms
10 new measurement concepts
> Distinguish and Choose between Methods A & B
> Overview of the 5-Step Method
2 Methods in BOMA-10
> Both methods use identical interior gross area
> Both methods use same space classifications
Major vertical penetrations Occupant areas
Service and amenity areas Occupant storage
Parking
Base building circulation required for Method B only
> Both methods measure space identically
The same boundaries for all classes of space
> Both methods produce identical rentable areas
for the building as a whole
Distribution of rentable area between floors will be different
Method A “Legacy”
> Calculations work like BOMA-96
Uses both Floor R/U factor and Building R/O factor Load factors vary by floor
> Utilizes actual corridors on multi-tenant floors
Can be field measured without plans
Less need for CAD to document base building circulation Likely less need for extended circulation
> Rentable areas of individual tenants will vary from
BOMA-96, but much less than Method B.
> May be only option for some office buildings
Base building circulation can be difficult in office buildings with dispersed core elements and certain design features
Method B “Single Load Factor”
> Same Building Total Rentable Area as Method A
> Re-allocates the Rentable Area of a building so
that the Load Factor is the same on all floors.
Rentable areas of individual tenants will vary from BOMA-96 mor than Method A.
> Requires base building circulation on every floor
Base building circulation must be documented on paper or CAD Cannot be field measured
> Rentable area is calculated using the Single Load
Factor applied to the multi-tenant occupant area
of every floor
Since a full floor tenant actually can use the area in base building circulation, a “full floor equivalent factor” is calculated that is comparable to a full-floor load factor.
Method B
Generally, how it works:
> Determine Building Total Rentable Area
Total of Preliminary Floor Area for all floors
(Interior Gross Area less Major Vertical Penetrations)
> Determine Building Total Occupant Area
Assume multi-tenant corridor on every floor (Base Building Circulation)
> Determine Single Load Factor
Building Total Rentable Area divided by Building Total Occupant Area
> Determine Rentable Area of each floor
Single Load Factor times Occupant Area of each floor
Same Rentable Area for single tenant occupancy as for multiple tenants on the floor.
Base Building Circulation
> Minimum corridor on multi-tenant floor to access
Occupant areas, Egress stairs, elevators Restrooms, janitor’s closets & water coolers Life safety equipment & refuge areas Building service and amenity areas
> Width set by building design standard
Typically 5’ to 6’ wide (not 44” – code minimum)
Goal is to be same width as actual corridors on most floors
> Used for Method B (Single Load Factor) only
Must document boundaries on CAD or paper Can’t field verify
> Can be difficult to determine in some buildings
May suggest use of Method A.
Base Building Circulation
Extended Circulation
> On multi-tenant floors, when Base Building
Circulation has to be extended to provide access
or egress to an Occupant.
> Corridor space not allocated by R/U ratio
In addition to Base Building Circulation (Method B)
In addition to existing corridor if leases are signed on floor (Method A)
> Included in Occupant Area of those requiring it
One occupant – part of their usable area
Several occupants – pro-rate based upon usable area
Extended Circulation
Method A & B
> Do not mix „n‟ match!
Must pick either Method A or Method B to apply to entire building
> Clearly identify which method is applied
In leases
In any presentation of rentable area: Marketing materials
Pro-formas Appraisals

The 5-Step Method
1. Measure interior gross area (IGA)
2. Classify all IGA space
3. For each class of space, determine boundary lines
4. Calculate the areas of all classes of space
Global summary of areas calculates rentable areas
5. Disclose certain areas
Restricted headroom, vault space, connectors & mezzanines
(Optional) Cap load factor to market
