An Act amending the act of August 15, 1961 (P.L.987, No.442), known as the Pennsylvania Prevailing Wage Act, further providing for definitions, for specifications and for duty of secretary.

Added a specific exemption for HVAC duct cleaning projects funded by public bodies, removing them from the prevailing wage requirements.

Clarified that custom fabrication and repair work with minimal on-site construction is now considered 'public work' subject to prevailing wages.

Created a new definition for 'School Safety and Security Improvements' covering projects recommended by official assessments or funded by specific school safety grants.

Established a new threshold of $50,000 for the new school safety category, which is higher than the standard $25,000 threshold for other public works.

Defined 'Residential Property' as properties with fewer than eight units, excluding municipal housing authorities in first-class cities.

Modified the general definition of 'public work' to exclude the newly defined school safety improvements and residential property rehabilitation, creating a distinct regulatory path for these projects.
