A pre-employment physical for a construction job is a medical exam given after a conditional job offer and before the person starts work. Under the ADA, an employer may not ask applicants to take a medical exam before making an offer. It may require the exam afterward only if every new hire in the same job has to take it. For HVAC and plumbing contractors, the exam works best when it is tied to written job demands such as lifting, ladder work and heat.

TL;DR

• Schedule the exam only after a conditional offer, never before.
• Give the same exam to everyone entering the same job category.
• Send the clinic a written list of the job’s physical demands so the exam measures the real work.
• Keep results confidential and separate from personnel files. Supervisors get restrictions, not diagnoses.
• Drug tests and physical agility tests follow different timing rules than medical exams.

What a construction pre-employment physical is

A pre-employment physical, also called a pre-placement exam, checks whether a new hire can safely perform the essential functions of the job. It usually covers health history, vital signs, and vision and hearing. Employers can add job-specific checks.

For mechanical contractors, the job-specific part matters most. A service technician who climbs into attics and carries condensers has different demands than a project manager who splits time between the office and the site. A physical without a job analysis turns into a general checkup, which tells you little about whether the person can do the work you hired them for.

When contractors may require one

The ADA’s timing rule has three parts:

1. Before an offer: no medical questions and no medical exams. The EEOC’s guidance says this applies even if the employer plans to look at the results only after the offer.
2. After a conditional offer: the employer may ask disability-related questions and require an exam, as long as it is done for all entering employees in that job category.
3. Before the person starts duties: 29 CFR 1630.14(b) allows the exam in this window, and the offer can be conditioned on the results.

The ADA applies to companies with at least 15 employees, according to the Texas Workforce Commission. Smaller contractors should still check state and local rules. Contractors hiring across state lines should review our guide to multi-state hiring compliance.

What the exam typically includes

A typical exam includes a health history, vital signs, vision and hearing screens, a musculoskeletal check, and job-specific tests such as a lift, climb or respirator clearance. A drug test, a chest X-ray or a psychological evaluation is a separate order. It is not included just because the form says “physical.”

The panel for construction and field service roles usually adds lift, carry, climb and balance checks. A DOT exam applies only when the offer includes CDL driving.

Physical ability tests for trades

Construction ability tests typically include lifting at various heights, carrying over set distances, pushing and pulling, ladder climbing, and tolerance for standing, kneeling or crouching. For a plumber, that might mean carrying fixtures and working in a crouch under a slab. For an HVAC installer, it might mean moving equipment up a ladder.

Drug tests and agility tests are different

The Texas Workforce Commission notes that drug tests are not medical examinations under the ADA and may be given at any time. Physical agility tests are also not medical exams, but they must be given to all applicants in that job category at a particular stage of hiring. If a test tends to screen out people with disabilities, the employer must be able to show it is job-related and consistent with business necessity.

Employers may also ask applicants whether they can perform specific job functions. They may ask applicants to describe or demonstrate how they would do job tasks, even before an offer. A paid, one-shift trial is one way to see this in practice, and our article on working interviews and FLSA risk covers how to structure it.

Write the job demands before you schedule anyone

The exam is only as good as the job information behind it. Before the first candidate goes to the clinic, write down the essential lifts, carry distances, ladder or scaffold use, driving, respirator use, heat and shift length. Give that description to the examining physician. Holcombe Medical Consulting suggests including items like working in stooped positions, lifting and placing components, and staying alert around operating equipment.

Some roles also fall under OSHA medical surveillance requirements, such as respirator use. The employer is responsible for telling the clinic when a role carries one of these.

For stronger programs, a clinic can tour the worksite. MRA’s guidance suggests the clinic evaluate each position and its environment, and that the provider give a written review of the applicant’s capability to do the job.

Keep the process fair and defensible

Three habits protect contractors:

1. Same exam for everyone in the job category. If you test one service technician, test all of them.
2. Validated, job-related criteria. The EEOC says selection procedures should be properly validated for the positions and purposes for which they are used, and updated when job requirements change.
3. Individualized decisions. Exclusion criteria used to screen out people with disabilities must be job-related and consistent with business necessity, and the job cannot be performable with reasonable accommodation, per 29 CFR 1630.14(b)(3). Before withdrawing an offer, the question is whether this person, with their current condition and any reasonable accommodation, can safely do the job. It is not whether they have a particular diagnosis.

Offer letters should state that the offer is conditional on the exam. Our pages on construction offer letter clauses cover this wording.

Handling results and accommodation requests

Under the ADA regulation, information from the exam must be collected and maintained on separate forms and in separate medical files and treated as confidential. Supervisors can be told about work restrictions, not diagnoses. Family medical history should stay off the questionnaire.

When a need for accommodation is not obvious, SHRM’s toolkit advises sticking to job-related information, storing medical information securely and apart from the personnel file, and documenting the process. It also suggests focusing on essential duties and considering multiple accommodation options.

Our perspective

Contractors often treat the physical as a box to tick after the hire is made. We see it as one step in a structured hiring process that starts with a clear definition of the role.

At Petra Talent we focus only on HVAC and plumbing recruiting. Our approach combines role-specific sourcing, technical vetting and credential verification, so a candidate reaches the offer stage already screened against the real demands of the trade. That makes the post-offer exam a confirmation step instead of a surprise.

We also encourage contractors to write job demands down early. The same document supports the offer letter, the clinic referral and onboarding, and it keeps the process consistent for every hire in the category.

How Petra Talent helps contractors hire before the exam

A physical only matters if the right candidate gets the offer. We source and vet HVAC and plumbing professionals for service, construction and leadership roles across the United States. Our performance-based screening and HVAC skill tests assess skills before you extend an offer.

Our placement fee is 18% as a one-time fee, with details on our pricing page. To start a search, see our HVAC recruiting services or plumbing recruiting services.

FAQ

Can a contractor require a physical before making a job offer?

No. The ADA bars medical exams and disability-related questions before a job offer. After a conditional offer, you may require an exam if all entering employees in that job category take it.

Is a drug test part of a pre-employment physical?

Not automatically. Drug tests are a separate order, and the ADA does not treat them as medical examinations, so they may be given at any time. Confirm with the clinic what is on the order.

Is a lifting test the same as a medical exam?

No. Physical agility tests measure job tasks such as lifting or climbing and are not medical exams under the ADA. They must still be given to all applicants in the job category at the same stage of hiring.

Who should see the results?

Keep medical records confidential and separate from personnel files. Supervisors can be told about restrictions that affect work, not the diagnosis.
