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

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.

Summary

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)

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.)

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
