Which method involves multiplying the cost per unit of measure of each component part of a structure?

The method that involves multiplying the cost per unit of measure of each component part of a structure is the unit-in-place method. This approach focuses on assessing the costs associated with each specific component—such as walls, roofs, and floors—by multiplying the unit cost of each part by the measure of that part. This makes it highly accurate, as it takes into account the actual costs associated with materials and labor specific to each unit.

This method is particularly effective because it allows for detailed itemization and can provide a more precise total cost estimate for a structure. By evaluating each component individually, appraisers can better understand the total expenses involved in construction or replacement scenarios.

In contrast, other methods like square-foot and quantity survey have different scopes; square-foot focuses on the overall cost per square foot of the entire building, and a quantity survey involves a more detailed breakdown but is more comprehensive than strictly unit pricing. The index method relies on established indexes to estimate values but doesn't involve multiplying by unit costs directly.
