Study note

Public works is the smallest section — about 5% of the exam — but it has its own vocabulary, and missing that vocabulary makes these questions impossible even though they are often straightforward.

A public works project is construction paid for with public funds: a city hall, a school, a courthouse, a road. Because public property cannot be liened, and because the Legislature wants public money to support the area's construction wage standard, public work is governed by prevailing wage law: workers must be paid the prevailing wage determined for their craft in the locality where the project is located. Expect questions about prevailing wage determinations, how to find the applicable determination, and what happens when a determination changes mid-project.

Alongside prevailing wages runs the paperwork. Contractors on covered projects must submit certified payroll records — regular reports of each worker, classification, and wage — and falsifying them is its own offense. Registration is another theme: contractors bidding on or performing public work must be registered with the Department of Industrial Relations, and an unregistered contractor cannot bid or be listed as a subcontractor. Public works awards can also carry apprenticeship obligations.

The money flows through tiers: the general contractor, subcontractors, and lower-tier subcontractors. Know the order of payment obligations and the role of retention — the portion of payment withheld until completion — plus how a contractor recovers retention and how payment bond claims substitute for lien rights on public jobs.

Penalties tie the section together: failing to pay prevailing wages, failing to register, or failing to file certified payroll each carry administrative consequences that can cost a bid, a contract, or the registration itself.

When practicing, tag each scenario: is the project public, is the contractor registered, which determination applies, and which obligation — wage, record, or registration — is being violated. With so few questions per exam, the answers are mostly about recognizing which rule is in play.
