Where can the footers be located in construction blueprints?

In construction blueprints, footers are most accurately represented in foundation plans. This is because foundation plans specifically detail the layout and dimensions of the foundations and footings that support the structure. These plans illustrate where footers are to be placed, including their dimensions, depth, and types of materials to be used. By providing this information, foundation plans ensure that the construction meets structural integrity and safety standards, which are critical for the overall stability of the building.

In contrast, roof plans, elevation plans, and site plans serve different purposes. Roof plans focus on the layout of the roofing elements, elevation plans show the exterior views and design elements of a building, and site plans provide an overview of the property, including the placement of the building, landscape, and utilities. None of these plans would provide the detailed information specific to footers that foundation plans do. Therefore, the correct answer is the foundation plans, where the footers are explicitly detailed for construction purposes.
