     (1) Work includes, but is not limited to:

     • Source removal methods that employ vacuum units and compressed air to loosen dirt and debris in HVAC systems and convey it to a containment device for proper disposal; and

     • Work that involves the attachment of the vacuum system to an existing port.

     (2) Work performed under this scope does not include:      • Creating service openings in the system as necessary in order to accommodate cleaning of otherwise inaccessible areas or the sealing of those service openings; nor

     • Removing and installing ceiling sections to gain access to HVAC systems during the cleaning process.

     Openings that are created for access and then sealed will utilize HVAC sheet metal rates of wage.

     Work utilizing mechanical or hand brushes and other tools to loosen dirt and debris for removal from HVAC systems will use the appropriate general laborer or mechanic wages.
