Furnishings, Finishes and Electrical - Electrical Cost Summary
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 (1)
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 - Concrete: Footing (3)
Foundation - Concrete: Slab Area Slab = Area House – Area Footings A 4 inch concrete slab was used
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
Fountation - Steel Reinforcing Rebars (3)
Foundation - Fiberglass Reinforcement Quantity necessary: 2 LB/CY Weight = (Volume Concrete) x (2 LB/CY)
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…)
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
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.)

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.
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 12.65/12 Must also include SF of overhangs SF of roof is equivalent to SF needed for shingles & paper underlay
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
Exterior Ceiling Calculate SF of ceiling Cost for furring strips Cost for drywall ceiling Cost for stucco
