Construction Industry

Construction workers are typically drug tested at multiple stages of employment, but it depends on the specific company’s construction drug testing policy. Most construction companies require a pre-employment drug test before a new hire starts work. After hiring, many employers continue with random drug testing throughout the year to deter on-the-job use of drugs or alcohol. It’s also common to test construction employees after any workplace accident or upon reasonable suspicion of drug use.

Yes, construction drug screening is very common for construction jobs. Because construction work involves hazardous tasks and equipment, many employers make passing a drug test a condition of employment. A typical construction company will drug test all new hires to ensure they are not using illicit substances that could impair judgment or motor skills. In addition, employers may perform ongoing testing, such as random screenings or post-accident tests.

Construction site drug testing commonly involves urine drug tests due to their cost-effectiveness and reliability in detecting substances like marijuana, cocaine, opioids, and amphetamines. Hair follicle tests, though less common due to higher costs, offer a longer detection period, identifying drug use up to 90 days prior.

Yes, most construction jobs do test for weed, especially during pre-employment screening and post-accident investigations. Due to safety concerns and federal regulations on certain projects, testing for THC remains common—even in states where marijuana is legal.

While there may not be a universal law mandating background checks for construction workers, in practice they are a standard part of the construction hiring process. Most construction companies will conduct background checks on new workers to verify their trustworthiness and qualifications. Employers run these checks to uncover criminal records, violent history, or fake credentials that could create risks on the job. Clients or regulations may explicitly require background checks for certain projects, especially government-funded or sensitive infrastructure jobs.

Even when not required by law, construction firms use background screening to ensure they're hiring reliable people. It helps them avoid potential problems like tool/equipment theft or chronic safety rule violators.

A background check for a construction worker will typically review several key aspects of a candidate's history. First, it usually verifies the person's identity and Social Security number to confirm they are who they claim to be. Then, the employer will conduct a criminal history search, checking national, state, and county records for any felonies, misdemeanors, or arrests that are relevant. This often includes looking at sex offender registries as well.

Employers also commonly verify past employment and references to ensure the candidate's experience is legitimate and that past employers had no issues with them. In the construction industry, it's important to validate any professional licenses or certifications (for example, a general contractor license or OSHA safety certifications) that the worker needs for the job. Some construction background checks will also include a motor vehicle records check, especially if the role involves driving company vehicles or operating heavy machinery.
