What is the formula for calculating the cost of building? ›

Cost of building = area of plot x construction rate per sq ft is the fundamental formula for calculating construction cost per square foot.

Calculate Quantity of Materials

It's easy to figure out – simply take the total amount of square feet that were measured for the project, then divide the total amount of square feet by the coverage rate of the material.

Around 1.8 cubic ft per sqft that makes a total of 1800 cubic ft for 1000 sqft.

Measure the length and width, in feet, of each room. Then, multiply the length by the width to calculate that room's square footage. For example: If a bedroom is 12 feet by 20 feet, it is 240 square feet (12 x 20 = 240). For each room, write the total square footage in the corresponding space on your sketch.

1. Unit pricing. This method of construction cost estimating is the most common. The unit pricing method is achieved by calculating the overall cost of the project based on unit costs.

Determining the construction labor cost

They are working 8-hour shifts, which will translate into a 40 hour work week. Crew's hourly rate X 3 (amount of workers) X 6 (number of weeks) X 40 (hours per week) = cost of the project.

To keep it simple and stick to a good average, say that 6.3 board feet are required for every square foot of house. So, a 1,000 square foot home would need 6,300 board feet to complete, while 12,600 board feet would be necessary for a 2,000 square foot home.

The formula to calculate price per square foot is price divided by size (in square feet). So for example, if you have a 2,000-square-foot house selling for $300,000 you take the total price, then divide it by the square footage, which would give you $150 per square foot.

To calculate direct material costs, add your beginning direct materials to your direct materials purchased and subtract the ending direct materials for the period.

A typical 2,000-square-foot home uses almost 16,000 board feet of lumber and 6,000 square feet of structural panels like plywood.

What are the material cost for 1200 sq ft house? ›

For the construction of a 2000 sq ft house, the total cost of the building @ Rs. 2000 per sq. ft will be around Rs. 40 lakhs to which add 20 % more towards miscellaneous and unforeseen expenses which cumulates to Rs.

Any space that has walls, flooring, ceiling and heat would count as finished square footage. So, it's likely that stairwells, closets, walk-in pantries and other areas you might be questioning would contribute to the square footage count of a home.

There are several types of cost estimates in the project, but the top classification of cost estimates is based on the functions; Design, bid and control. The three major types of construction cost estimates are design estimates, bid estimates, and Control estimates.

There are three types of estimates that can be used to communicate costs to clients, including ballpark, budgetary, and definitive.

Average General Contractor Rates

However, the general range that one would expect to pay is usually around $50.00 to $150.00 per hour. Other contractors don't charge an hourly rate. General contractors charge at about 10 to 20 percent of the total construction project cost.

Since framing projects are determined by the square foot, the larger the project, the more it's going to cost. While the average cost per square foot is between $7 and $16, the cost to frame a 1,000-square-foot home versus a 3,000-square-foot home is going to be significantly different.

A typical 2000-square-foot apartment house consumes 26,700 board feet, according to the Idaho Forest Products Commission. A “typical” tree with a 20-inch thickness and 42 linear feet of useful wood produces about 260 board feet. So, according to the math, that house should have utilized around 102 trees.

Multiply the total wall length (in feet) by 0.75 (for 16-inch on-center stud spacing). Add three studs for each 90-degree corner. Add four studs for each 45-degree corner. Add two studs for each wall intersection (where another wall abuts the wall you are estimating).

The average cost can range from $54 to $270 per square foot based on a home size of 2,600 square feet. These cost estimates are for a standard suburban tract house. Neither economy or luxury in quality, it's your typical suburban tract home. An economy home might cost as little as $33 per square foot.

Figure out the cubic yards or square footage by multiplying the length, width and height. You can use this information to help figure out how much concrete you need, for example. Once you know the specific dimensions, you can start to calculate the things you need for framing.

Examples of Material Costs

They include things like rags used in the construction of a house, thread used to stitch clothing together, and the lubricants or oil used on the machines that create the products or services.

A home with a simple and concise layout is the cheapest type of house to build. Ranch homes are typically single-story structures with attached garages. They're easy to find construction plans for and highly customizable, so you can find a home that fits your needs and budget.

When an appraiser calculates the square footage of a home, it will only measure interior spaces that are heated and cooled. This includes bedrooms (and closets), bathrooms, hallways, a kitchen, living areas, enclosed patios, and finished attics.

Stairways and closets will usually be included in the square footage length. When it comes to porches and other outdoor spaces, they're usually only included if they use the same heating system as the rest of the house.

To Fannie Mae and appraisers, a basem*nt, even if finished with high-quality materials, cannot count as square footage. It doesn't matter how good your basem*nt looks.

To find your roof's total square footage: Measure the length and width of each plane on the roof (including dormers) then multiply length times width. Add the square footage of each of the planes together.

What is considered livable square footage? ›

When house plan sellers refer to Total Living square feet, they are referring to the “living area” of the home. This can be thought of as the area that will be heated or cooled. It is called the living area because this is where you spend your time. An attic, while a useful storage area, is not living space.

To be considered “finished”, the area must have flooring, wall covering (trimmed) and ceiling. NOTE: Tax records may not be accurate – be sure to confirm correct square footage. Do NOT include unfinished areas such as laundry room, furnace areas, storage areas that are not finished.

The appraiser, on the other hand, evaluates the total value of a home. That means calculating square footage that includes everything, even an unheated basem*nt, attic, and other nonliving spaces.

The result is an overall percentage of completion that is then used for billing and revenue recognition purposes.

The cost of a structure is calculated approximately as the total cubical contents (Volume of buildings) multiplied by Local Cubic Rate. The volume of building is obtained by Length x breadth x depth or height. The length and breadth are measured out to out of walls excluding the plinth off set.
