Measurement Tools & Technique


TOOLS TO MEASURE AND COMPUTE AREA

� Pencil� Clipboard

� Tape Measure (100’ calibrated in tenths)

� Graph paper� Calculator

� May use laser on certain measurements


Why do we need a tape measure?

To get the length and width of the walls from the outside.

This allows us to compute area.




Outside – rain or shine!


Where to write measurement?

Measure on the outside = write dimension on the outside

Measure on the inside = write dimension on the inside, knowing that conversion to exterior dimensions

is necessary to comply with ANSI

Best practice: Measurement centered


The formula for the area of a rectangle is ?

Length X Width = Area

Feet X Feet = Feet Squared

(Square Feet)




Length

WidthLength X Width = Area


35’ 6”

33’6”

Compute the area of this box


Convert inches to tenths

6 inches = 0.5 tenths

12 inches

or ½ of a foot

Area =

1,189 feet squared




A tape measure calibrated in tenths

does not require the conversion

This is much more efficient!


ANSI Standard: Rounding

� Each wall dimension may be rounded to

the nearest tenth

�First place value after the decimal

� The final square footage is reported to the

nearest whole square foot


Graph Paper

� Enables you to draw to scale

� Recommend 10X10

�1 square = 1 foot

�Bold line to bold line = 10 feetFast and efficient!




Establish Point of Beginning

One Possible Technique:

� Solid Wall = Solid Line

�Living Area

�Garage

�Storage

� No Wall = Dashed Line

�Porch/covered patio

�Carport

Measurement Process

� Perform a walk-around

�Determine how to hold clipboard

�Look for hazards

�Determine where to set point of beginning

�Place street relative to point of beginning

�Best to begin at front left corner and proceed

counter-clockwise (to the right every pull)


Prior “Market” Definitions

� Finished

� Heated and Cooled

� Habitable

� Contiguous

� Measured from the outside




Finished

� Consistent finishes throughout

�Example: Good quality house with arecreation room addition of inferior quality

finishes. This is not “living area”.


Heated and Cooled

� ANSI is a national standard. It does not

address ventilation. This is addressed bythe general market. Treat heating/cooling

as a quality of finish. Remember

consistency.


Habitable

� Livable and accessible

�Example: Room on third floor accessible froma ladder in a closet is not considered

“habitable”




Contiguous

� Per ANSI, “Finished areas that are

connected to the main body of the house

by other finished areas such as hallwaysor stairways are included in the finished

square footage of the floor that is at the

same level.”


Contiguous

� Finished areas that are not connected to

the house by other finished areas cannotbe included in the finished square footage

at any level.


Per ANSI,

� Finished Area is computed for each level(areas of the house that are verticallywithin 2 feet of the same horizontal plane)

� Make a distinction between finished abovegrade and finished below grade

� Ventilation and lighting are not specifiedrequirements of the ANSI standard – referto market standard




ANSI Ceiling Height

Requirement


� Finished Areas must have a ceiling height

of at least 7 feet, except under beams,ducts, and other obstructions where the

height may be 6’4”

� If Ceiling slopes, ½ of ceiling height must

be at least 7 feet

� No portion of the finished area that has a

height of less than 5 feet may be included

in finished square footage

= =

3 Houses = Covered Base




30’ Base 30’ Base 30’ Base

= Not =

3 Houses = Covered Base, with ceiling height restriction

7’+7’+


STAIRS

� Stair treads are included as “walkable”

area of the ascending story, provided thatthe opening in the floor does not exceed

the area of the stair treads.

� Exception to the 5’ ceiling height – stairs

are included even through they slopebelow 5’


UP

Stairs fill the entire “well”

They are included in 2nd floor finished area

Stairs DO NOT fill the entire wellOnly portion with treads is included in 2nd floor finished area


MODULE 5

Measurement Computation and

Measuring Unique Structures


STEPS TO COMPUTE AREA

� Measure the Structure

� Convert any Interior Dimensions to

Exterior Dimensions

� Square the Structure

� Divide Structure into Geometric Figures

� Label, then Compute the Area of each

Figure

� Sum it up!




Measurement Reliability� Measure in accordance with the standard

� May use plans/prior drawing as a guide,

but must verify

� May outsource measurement, recommend

contract with qualified ANSI standard

knowledgeable person

Caution: Cloning an old listing – you are

liable!


Squaring the Structure

� STEPS FOR SQUARING THE

STRUCTURE (L=L and W=W)� Set up four columns: Front Side (FS), Back Side (BS), Left Side

(LS), Right Side (RS)

� Tally the dimension in the appropriate column along the designated

side

� Front should equal Back, if no adjustment(s) needed

� Left side should equal Right side, if no adjustment(s) needed

applied

� GOAL: Prove the structure to be mathematically squared, or FS =BS and LS = RS


Once squared

� You can continue manually

� You can put field drawing into a drawing

program




Check Squaring on this

structure



RESULT: The property is proven to be mathematically square, area calculation can begin. Draw your rectangles.




Let’s compute!


What if it doesn’t square

� ANSI allows you to round to the nearest

tenth. Provided adjustment is minimal(within a tenth) you can adjust the length

of a wall up or down to produce a

mathematically squared structure.


Compute: AREA by AREA

Remember: Begin with Living Area

Then compute other areas, area by area







Let’s take a look at unique structures
