Frequently asked questions
When is work solicited under 561210 instead of a single-trade code?
When the agency bundles multiple functions into one contract. A custodial-only contract uses 561720; custodial plus HVAC maintenance plus grounds in one PWS typically goes out under 561210. The bundle means broader licensing and staffing requirements — read the PWS scope carefully.
Is the high size standard good or bad for small businesses?
Good: at $47M in average receipts, established regional facility companies still qualify as 'small', and the government sets aside a large share of facility support work. The practical barrier is past performance breadth, which teaming or a strong subcontractor bench can solve.
