A Project Estimate Sheet is a document used to outline the estimated cost of a project. It provides an itemized list of all the materials, labor, and other resources required for a project and their associated costs. This document is used to budget for and manage the resources needed for a project. There are two main types of Project Estimate Sheets: Fixed Price and Time & Materials. A Fixed Price Project Estimate Sheet is used to produce a fixed cost for a project, regardless of the number of resources used. A Time & Materials Project Estimate Sheet is used to estimate the total cost of a project, based on the estimated time and materials needed.
