An employer can pay part of that as extra wages instead, as long as the total per hour stays at $107.98 or more.

Davis-Bacon boilermaker rate in San Mateo County
Federally funded or assisted construction here uses the U.S. Department of Labor's wage determinations. When a California awarding body runs a federally funded or assisted project, DIR's rates must be paid where they are higher than the Davis-Bacon rates (DIR public works FAQ).
We don't put a federal figure next to DIR's here, because this page leads with a classification the federal determinations don't list one to one. The federal rows for this trade are below; match the classification to the work.

Are you being paid this rate?
Add your hourly wage to what your employer pays into health, pension and other plans for you, and compare it with $107.98. Plan payments only count if the money goes into the plan; your pay stub won't show them, but plan statements will. The training amount goes to the California Apprenticeship Council or an apprenticeship program, not to you. Check a week of pay.
Contractors on most public works jobs file certified payroll with the state, and anyone can look it up in DIR's CPR public search. If your total comes up short, you can file a public works complaint with the California Labor Commissioner.
