How do you price a construction project?

PRICE / MARKUP FACTOR = COSTS Consider this example: If you know that a project should be priced at \$20,000, and your markup factor is 1.5 (50% markup), then you can calculate the costs of the proj- ect by dividing the PRICE by the MARKUP FACTOR. of LABOR, MATERIALS, SUBS, AND EQUIPMENT).

What is approximate estimate?

Approximate estimate is made to find out an approximate cost in a short time, without taking out actual quantities.

What is a high level cost estimate?

High-level estimates are not about making a commitment, they are really about setting and managing expectations around what is realistically possible. Once we’ve dealt with our highest priorities first… if there is extra capacity, we can deal with the other stuff we couldn’t get to the first time around.
