Enter all but one of the variables (A, C, H, R, L, W, D) into the calculator to determine the estimated cost for the demolition project; this calculator can also evaluate any of the variables given the others are known.

## Demolition Estimate Formula

The following formula is used to calculate the estimated cost for a demolition project:

EC = (A * C * H * R) + (L * W * D * R)

Variables:

- EC is the estimated cost for the demolition project
- A is the area of the structure to be demolished (in square feet)
- C is the cost per square foot for demolition
- H is the height of the structure to be demolished (in feet)
- R is the complexity rating for the demolition project (a factor between 1 and 10)
- L is the length of the structure to be demolished (in feet)
- W is the width of the structure to be demolished (in feet)
- D is the depth of the structure to be demolished (in feet)

To calculate the estimated cost for a demolition project, multiply the area of the structure by the cost per square foot, the height of the structure, and the complexity rating. Then, add the product of the length, width, depth, and complexity rating to the previous result.

## What is a Demolition Estimate?

A demolition estimate is a detailed calculation of the costs associated with tearing down a structure, such as a building or a house. This estimate is typically provided by a professional demolition contractor and includes various factors such as the size and type of the structure, the materials used in its construction, the method of demolition to be used, the disposal of debris, and any necessary permits or inspections. The estimate may also factor in potential complications, such as the presence of hazardous materials like asbestos or lead, which require special handling and disposal. The demolition estimate provides a comprehensive overview of the expected costs, allowing property owners to budget appropriately for the project.

## How to Calculate Demolition Estimate?

The following steps outline how to calculate a Demolition Estimate:

- First, determine the size of the structure to be demolished (in square feet).
- Next, determine the type of structure (e.g., residential, commercial, industrial).
- Next, research the average cost per square foot for demolishing the specific type of structure.
- Calculate the estimated cost of demolition by multiplying the size of the structure by the average cost per square foot.
- Consider additional factors that may affect the cost, such as hazardous materials removal, site accessibility, and disposal fees.
- Adjust the estimated cost based on these additional factors.
- Finally, present the Demolition Estimate to the client or relevant parties.

**Example Problem:**

Use the following variables as an example problem to test your knowledge:

Size of structure (in square feet) = 2000

Type of structure = Residential

Average cost per square foot for demolishing a residential structure = $10
