In case of violation, who needs to correct the spatial relationship issue?

The correct response indicates that the last installer has the responsibility to correct any spatial relationship issues that arise from their work. This is based on the principle that those who perform the installation of equipment or components are directly responsible for ensuring that their installation adheres to the appropriate codes, standards, and specifications, which include considerations about spatial relationships.

When an issue is identified, the last installer is typically in the best position to make the necessary adjustments. They have firsthand knowledge of the existing setup and any particular challenges encountered during the installation process. This accountability encourages a higher standard of work and helps ensure safety and compliance with regulations.

The other parties, such as the regulatory authority, facility manager, and building owner, may play different roles in oversight, management, or enforcement but do not have the direct responsibility for the corrections needed in this scenario. Hence, it's primarily the responsibility of the last installer to address any violations pertaining to spatial relationships associated with their work.
