Turn up early, bring your own hand tools and boots, and expect to spend the first hour signing in and sitting through an orientation rather than working. Nobody will explain the hierarchy to you, so learn it fast: the general contractor runs the site, the superintendent runs the day, your foreman runs you. Ask questions on day one, because the new person who asks is normal and the new person who guesses is dangerous. Here is what actually happens and what to ask.
Before you go
Confirm the basics the night before. Start time, address, where to park, which gate, and who to ask for. Sites are big, parking is often a walk away, and being late on the first morning is the only first impression you get.
Sort your paperwork. If you are starting as an employee, your first morning includes a W-4 for tax withholding and an I-9 for work authorization, and the I-9 needs original documents. Take your ID and whatever else you were asked for. Not having it is a wasted morning for both of you. If you are being taken on as a 1099 subcontractor instead, that is a different arrangement with different consequences, and it is worth knowing which one you are before you start: 1099 vs W-2: which are you really? and 1099 or W-2? Worker Status Checker.
Check whether you need an OSHA card. Federal OSHA does not require the 10-hour or 30-hour card, but many states, cities and general contractors do require it by law or by contract, so in practice most construction workers end up needing one. Ask before the first day rather than being turned away at the gate. Do I need an OSHA 10 or 30 card? has the detail, including that a card which never expires federally can still be treated as out of date by the state or the general contractor.
Bring food and water. There may be nowhere to buy either, and on a hot site water is a safety issue rather than a comfort one.
What actually happens on the first morning
Expect the first part of the day to be administrative, and expect it to feel like a waste of time. It is not.
Sign in. Most sites keep a log of everyone on site, and on larger jobs you may get a badge. Sign in and out every day, because that log is the record of who was where if anything ever goes wrong.
Site orientation. Usually a talk, sometimes a video, sometimes both. It covers the site rules, the hazards specific to this job, where the emergency assembly point is, who the first aid and safety people are, and what to do if there is an incident. Listen to the parts about this site rather than the generic parts; the generic parts you will hear again. There is a full guide to what a good one covers and what you are owed: Site orientation and safety training: what you must be told.
A toolbox talk. Short daily or weekly safety briefings on a specific topic. They are normal, they are brief, and turning up to them is part of the job.
Then you get put with somebody. Usually the person you will be working under, and often with no introduction. Ask their name.
Who is who on a US site
Nobody will draw you this map, and getting it wrong is the fastest way to look green.
- General contractor (GC). The company running the whole job and answerable to the owner. On a shared site the GC is usually the controlling employer for safety purposes.
- Superintendent, usually just "the super". The GC's person on the ground, running the day-to-day and the schedule. The most important person on most sites.
- Project manager. Runs the job from the office: money, schedule, submittals, and the paperwork. You will see them less.
- Foreman. Runs a crew. Yours is the person you take direction from and the person you tell when something is wrong.
- Subcontractor, "the subs". The specialist companies doing each trade. You probably work for one.
- Safety officer or safety manager. On larger jobs, the person responsible for the safety program. Worth knowing by sight.
- The competent person. An OSHA term rather than a job title: somebody able to identify hazards and with the authority to fix them. Different tasks need different competent people, and knowing who yours is matters. What is a "competent person" and why every job needs one.
- The inspector, or the AHJ. The authority having jurisdiction. Not part of the job, and there to check the work against code.
The practical version: your foreman gives you your work, the super runs the site, and the GC is who both of them answer to.
What to take with you
Your own boots and basic PPE that you keep. Ordinary safety-toe boots are one of the few items an employer can make you buy, because you take them home. Almost everything else the job requires, they provide and pay for.
Your own hand tools. Most trades expect you to arrive with your own basic hand tools. Power tools, access equipment and anything specialist are normally the employer's. What that split actually looks like is in Tools and PPE: what you buy and what the employer provides.
Mark everything. Tools go missing on sites, sometimes by accident and sometimes not. Mark yours, keep a list with serial numbers, and do not leave them out. Stop your tools getting stolen (and what to do if they are) and the Equipment Register.
The rule that keeps you employed and alive: ask
New people worry that asking questions makes them look stupid. On a construction site the opposite is true. The person who guesses at something they do not know is the person who gets hurt or ruins somebody else's work, and everybody experienced has seen it happen.
Worth asking on day one:
- What are the hours, and when are the breaks?
- Where do I sign in, park, eat, and find a bathroom?
- Who is my foreman, and who do I go to if they are not here?
- What is the hazard on this site I should know about that I would not guess?
- Where is the first aid kit, and who is the first aid person?
- What do I do if I see something unsafe, or if I get hurt, however minor?
- Which tools am I expected to bring, and which do you provide?
- Is there anything on this site I am not allowed to touch or operate?
That last one matters more than it sounds. Do not operate equipment you have not been trained and authorized on, and do not use somebody else's tools without asking.
The four things that actually kill people
You will hear about the Focus Four, and it is worth knowing them on your first day rather than your fiftieth: falls, struck-by, caught-in or between, and electrocution. Those four cause most construction deaths every year.
The two numbers to carry in your head: fall protection is required at 6 feet or more above a lower level in construction, and at 10 feet on scaffolds, with holes and skylights protected at any height. Residential work is not exempt from this. And keep general equipment at least 10 feet from overhead power lines, 20 feet for a crane.
The Focus Four: the hazards that actually kill on site is the full version, and When do I need fall protection, and what counts? is the one you will meet first.
You have rights from day one, including the new-person ones
Two are worth knowing before you need them.
Safety. You have the right to a safe workplace, to the safety gear the job requires at no cost to you, and to raise a hazard without being punished for it. Retaliation for raising a safety concern or contacting OSHA is illegal under Section 11(c) of the OSH Act. There is a narrow right to refuse genuinely dangerous work, and it is narrow, so read it before you rely on it: Your rights on an unsafe site.
Everything else. Pay, overtime, breaks, harassment and discrimination protections apply from your first shift, not after a probation period. Those are in Your rights in the first months on the job.

Common questions
What should I bring on my first day on a construction site?
Your own safety-toe boots and basic hand tools for your trade, plus food and water, since there may be nowhere on site to buy either. Bring original ID documents too, because if you are starting as an employee your first morning includes a W-4 for tax withholding and an I-9 for work authorization, and the I-9 needs originals. Check the night before whether the site or the general contractor requires an OSHA 10 card, because many do by law or by contract even though federal OSHA does not mandate it, and turning up without one can mean being turned away at the gate.
What happens on the first day on site?
Less work than you expect. The morning is usually signing in, paperwork, and a site orientation covering the rules, the hazards specific to this job, the emergency assembly point, and who the first aid and safety people are. There may be a short toolbox talk as well. Then you get put with somebody, often with no introduction. Sign in and out every day from then on, because that log is the record of who was on site if anything ever goes wrong, and listen hardest to the parts of the orientation that are about this particular job rather than the generic safety content.
Who is in charge on a construction site?
The general contractor runs the whole job and answers to the owner, and on a shared site is usually the controlling employer for safety. The superintendent is the general contractor's person on the ground running the day and the schedule, and is the most important person on most sites. Your foreman runs your crew and is who you take direction from and who you tell when something is wrong. Subcontractors are the specialist companies doing each trade, and you probably work for one. Separately there is the competent person, an OSHA role rather than a job title, and the inspector or AHJ, who is not part of the job.
Is it bad to ask a lot of questions when you are new?
No, it is the opposite. Guessing at something you do not know is how people get hurt and how somebody else's work gets ruined, and everyone experienced on site has watched it happen. Ask about the hours and breaks, where to sign in and park, who your foreman is, the hazard on this site you would not guess at, where the first aid kit is, what to do if you are hurt however minor, which tools you are expected to bring, and whether there is anything you are not allowed to touch. Never operate equipment you have not been trained and authorized on.
Do I need an OSHA 10 card to work on a construction site?
Federal OSHA does not require it, but many states, cities and general contractors do require it by law or by contract, so in practice most construction workers end up needing one. The 10-hour card is basic hazard-awareness training for entry-level workers and the 30-hour is the deeper version for supervisors. It is safety training, not a trade license, so it does not qualify you for licensed work. Federally the card has no expiration date, but several states and cities that require it also require renewal, so a card that never expires federally can still be treated as out of date.
The honest bit
- The site roles here are the common US pattern, not a rule. Titles and who does what vary by company and by the size of the job.
- The 6-foot fall protection trigger, the 10-foot scaffold trigger, the 10 and 20 foot power line clearances and the Section 11(c) retaliation protection are federal OSHA positions as recorded in this site's own safety guides. State-plan states can be stricter, so check what applies where you work.
- Whether an OSHA card is required, and whether it has to be renewed, is decided by your state, your city or the general contractor, not by federal OSHA.
- What paperwork you complete on day one depends on whether you are hired as an employee or engaged as a subcontractor, and those are genuinely different arrangements with different rights.
- This is general guidance, not legal advice.
