Repair job or maintenance contract?

Some notices are one-time repairs or installs, others are recurring maintenance over a base year and option years, which can fall under the Service Contract Act instead. The wage determination attached to the solicitation tells you which.

Go to the site visit

Mechanical solicitations often hold a site visit and list the equipment, makes and models. Read every amendment before you price.
