What part of a wood frame building is usually estimated first?

In the context of estimating a wood frame building, the floor framing is often estimated first because it serves as the foundational support for the entire structure. The floor framing sets the layout and dimensions for the subsequent elements of construction, including the walls and roof. This early estimation is critical as it informs other cost assessments related to wall and roof systems, ensuring that all dimensions and load-bearing requirements align correctly with the overall design of the building.

Estimators focus on the floor framing first because it establishes the baseline upon which all other structural components are erected. Functionally, it has implications for the load distribution throughout the building and can impact material quantities and labor costs associated with other parts of the project. In many cases, accurate floor framing estimates can streamline the overall estimation process by providing clear reference points for subsequent structural elements.

While external walls, roof framing, and window installations are vital components of a wood frame building and will require careful consideration during the estimating process, they logically follow after establishing the floor framing, as the latter determines how these elements will interact with the overall design and structure of the building.
