According to ABBA Division 1 specification, who is responsible for hiring a testing and inspection agency?

The owner is typically responsible for hiring a testing and inspection agency according to the ABAA Division 1 specification. This responsibility is rooted in the owner's role in the construction process, where they have the authority and financial incentive to ensure that the project meets specific performance standards and building codes. By hiring the testing and inspection agency, the owner ensures that independent assessments are conducted, ultimately aiming to validate that the building's airtightness and overall quality align with the project's requirements.

This arrangement allows the owner to maintain control over critical project specifications and ensures that inspections are conducted impartially and professionally. An independent testing agency can provide an objective review of the construction work, which adds a layer of accountability and can help prevent costly rework or compliance issues later in the project lifecycle.
