Summary by Nicholas Miller
Exterior Walls – Example Wall #2 Studs:
36.17ft – 3.00ft = 33.17ft
33.17ft / 16inch = 26 studs
Extra studs:
2 studs x 1 corner
2 studs x 1 door 2 extra studs
Total # studs = 32 x 8ft = 255 ft
Top Plate:
36.5ft x 2 plates = 75 ft
Sill:36.17ft
Door & window headers:1 door (width 32”) + 3inch = 35” x 2 = 5.83 ft
• Anchor bolts: 36.17ft / 24inch = 18
• Plywood / Insulation / Drywall / Exterior finish:36.17ft x 8ft = 289.33 SF Area openings = 21.64Area without openings = 289.33 – 21.64 = 267.69SF

Furnishings, Finishes and Electrical -Cost Calculation
Material Cost Source: RS Means, Homedepot.
Labor Cost Source: Most of them were doubled from material cost.
For example:
Material cost for Bollard is $89.98 given by Homedepot, and the labor cost will be $179.96.
Foundation - Earthwork: Excavation
The volume of earth to be excavated is the same as the volume of concrete in the footings.
There is no forming since the concrete will be poored directly into the trenches.
Foundation - Concrete: Footing (2)
Exterior & Porch Footings are 18"D x 16"W
Interior Footing is 12"D x 12"W
The length of the footings was calculated and multiplied it by their corresponding square foot cross section area
Then the volume of the junction between the footing and the slab was calculated.
Foundation - Steel Reinforcing Rebars (1)
25 inches overlap between the rebars
Two #5 rebars for Exterior & Porch Footings
One #5 rebar for Interior Footing
Foundation - Steel Reinforcing Rebars (2)
20 ft long #5 rebars were used
The number of bars necessary for each footing section were calculated
We minimized the waste when adding all the rebars together
Foundation - Fiberglass Reinforcement
Quantity necessary: 2 LB/CY
Weight = (Volume Concrete) x (2 LB/CY)
FlooringVinyl tile flooring was implemented throughout
the house since it was not specified in the plan (must be specified by owner).
Area Floor = Area House – Area Walls – Area Minor Components (Shower, Bath…)
Interior Walls Process similar to exterior
walls Key difference: Single Top
Plate
1. Calculate total lineal footage of interior walls (separate 4” & 6”)
LF used to calculate studs, trim, plating
2. Multiply by 8ft for sf of walls
SF used to price drywall, paint, insulation
INSULATION ONLY IN BEDROOMS
Things Not to Forget!2 additional studs per corner, intersection, or
opening
1 additional stud per interior wall
Double Headers above all openings2x4 on doors, 2x6 on the two larger bedroom
closets
Interior paint should be applied twice!
Trim along the bottom of the wall!
Fasteners!!! (Nails, etc.)
Roofing, Truss PackagePre-fab truss package
delivered at $3000 for mat. Cost.
Aspenational.org offers price ratios to obtain equipment and labor costEquip.~0.22xMat.Lab.~0.32mat.
Roof, Surface AreaRoof slope is 12:4,
therefore, the hypotenuse is ~12.65SF of roof is equal to
SF of hor. Plane multiplied by 12.65/12
Must also include SF of overhangs
SF of roof is equivalent to SF needed for shingles & paper underlay
Things Not to ForgetHurricane straps & nails (Different kinds and
prices)
Attic insulation equal to SF of horizontal SF
Flashings
Fascia and soffit
Need ledger board and a 2x4 header for the valley
Exterior Ceiling1. Calculate SF of ceiling
2. Cost for furring strips
3. Cost for drywall ceiling
4. Cost for stucco
