Modeled Square Foot Estimate

A modeled square foot estimate, or sometimes simply referred to as a square foot estimate, uses several building characteristics related to important building systems to construct a model building cost per square foot of area. The estimate can account for varying structural systems, facade systems, perimeter quantity, and other project add-ons. The method used in this class will be from the Guardian Square Foot Estimating Guide.

prime contractor

A prime contractor holds a direct contract with the owner or developer of a facility.

Rough Order of Magnitude (ROM)

An estimating approach that provides a rough estimated construction cost. In this course, we will use the Reported Square Foot estimating approach within the Guardian cost estimating guide for performing a Rough Order of Magnitude estimate. Note that project team members may have their own databases of previous construction costs that would allow them to perform the ROM estimates with historical cost information.

self-performing

When a construction company 'self-performs' work, they will have their own employees, e.g., carpenters, laborers, etc. putting the work in place on the construction site. It is important to note that many construction management firms do not self-perform much work on a project.

Specialty Contractor

A specialty contractor performs a specific scope of work on a construction project.
