The benefits of computerized estimating are that it can reduce calculation errors, increases the speed at which estimate is prepared, allows the estimator to track where quantities came from, and to quickly change a price or a productivity rate and get an instantaneous change in the projects cost.Most of the construction estimating services are used for building structures like residential, office, retail and industrial buildings.

It is not an easy job to complete but it is very necessary and it requires accurate information and proper analysis to avoid any errors.The first step of the process includes estimating the total cost of the project.

Next is to consider the quantity of the total cost which includes the scope of the project, labor cost, and the subcontractor's quote.

This is the simplest method of estimating the cost of a construction project and the estimation considers the material quantities, labor hours, material cost and the material cost reductions that arise due to the use of machinery.

It is the best method of estimating the materials quantity because the quantity of the raw material may vary depending on the needs of the construction company.

Estimating of the cost of this program is done by looking at the number of complaints regarding the work done by the contractors.
