Delaware DOL determinations effective March 13, 2026, effective March 13, 2026.

One rate, fringe benefits included: $71.54

DOL publishes a single hourly figure that already includes fringe benefits. A contractor can pay it all as wages, or pay part as contributions to bona fide benefit plans for the worker, as long as the two add up to at least $71.54. DOL doesn't publish a base and fringe split, so this page doesn't invent one.

DOL's data note: Delaware publishes one hourly rate per classification that already includes fringe benefits (19 DE Admin. Code 1322 s.3.1.9 and 3.1.12). There is no base/fringe split to add up, so base and the fringe fields are null and total_straight_time is the printed rate.

When does this rate change?

A project uses the rates in effect on the date its specifications are published, or the rates at contract signing if that is more than 120 days later (Regulations 6.3).
DOL issues one set a year, on or before March 15; this one took effect March 13, 2026. Mid-year amendments only correct errors and don't change awarded contracts (Regulations 6.4).
