4. 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 = SF
Area openings = 21.64

Total Area Ceiling – Area Ceiling Porch – Total Area Thickness of walls (interior and exterior)
Furring strips
(Length of wall/distance strips) x Width – LF Area of the porch

Area Ceiling
40ft x 36.5ft – (3.75ft x 14.75ft + 5ft x 4.67ft) = 1,384 SF

25. 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.

26. Foundation - Concrete: Footing (1)

27. 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.

28. Foundation - Concrete: Footing (3)

29. Foundation - Concrete: Slab
Area Slab = Area House – Area Footings
A 4 inch concrete slab was used

30. Foundation - Steel Reinforcing Rebars (1)
25 inches overlap between the rebars
Two #5 rebars for Exterior & Porch Footings
One #5 rebar for Interior Footing

31. 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

32. Fountation - Steel Reinforcing Rebars (3)

33. Foundation - Fiberglass Reinforcement
Quantity necessary: 2 LB/CY
Weight = (Volume Concrete) x (2 LB/CY)

34. Flooring
Vinyl 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…)

35. Interior Walls Process similar to exterior walls
Key difference: Single Top Plate
Calculate total lineal footage of interior walls (separate 4” & 6”)
LF used to calculate studs, trim, plating
Multiply by 8ft for sf of walls
SF used to price drywall, paint, insulation
INSULATION ONLY IN BEDROOMS

36. Things Not to Forget!
2 additional studs per corner, intersection, or opening
1 additional stud per interior wall
Double Headers above all openings
2x4 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.)

38. Roofing, Truss Package
Pre-fab truss package delivered at $3000 for mat. Cost.
Aspenational.org offers price ratios to obtain equipment and labor cost
Equip.~0.22xMat.
Lab.~0.32mat.

39. Roof, Surface Area
Roof slope is 12:4, therefore, the hypotenuse is ~12.65
SF of roof is equal to SF of hor. Plane multiplied by /12
Must also include SF of overhangs
SF of roof is equivalent to SF needed for shingles & paper underlay

40. Things Not to Forget
Hurricane 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

41. Exterior Ceiling Calculate SF of ceiling Cost for furring strips
