Ever show up to a construction site in clean clothes, no PPE, and been stopped at the fence? You already know this issue is for you.

Network engineers get thrown onto active construction sites more often than anyone prepares them for. They hand you a set of floor plans, and a schedule that assumes everything is already built.

Nothing accounts for the culture shock of walking into an environment that runs on completely different rules than anything in Silicon Valley.

This is everything you need to know before you walk through your next construction site.

Generally most construction sites work “first shift”. In the U.S. that means 6:30a-3:30p. After that, the job site might be a ghost town if you need any help.

Working in a high-rise? You’ll need to use the service elevator to access the site. Sometimes a dedicated person needs to operate the service elevator and that means your site access will be limited to certain hours. Plan ahead and get a sense of the schedule before starting work.

Before the site gets far enough along to get its certificate of occupancy (other countries have their own equivalents, my experience is limited to the U.S.), you will need to use a hardhat, hi-vis vest, and safety shoes. If the service elevators or temporary lifts are not functional, the stairs are your option for transiting between floors.

Understanding who does what, and who you actually have to talk to, determines whether you get your tasks done or sit around playing dumb.

The General Contractor (GC) controls the overall project. They hire subcontractors, own the schedule, and are legally responsible for everything that happens within the work site. You are almost certainly a sub under the GC, either directly or through a low-voltage contractor. That distinction matters: know who your contract is with.

The Superintendent ("the Super") is the GC's person on the ground. They control daily access to spaces, resolve task conflicts between trades, and decide whether you get to work in a particular area today or get told to come back another day.

Electricians, HVAC, plumbing, drywall, and low-voltage contractors become your peers on the site. You’ll share space with them, including claustrophobic MDFs and IDFs.

Plan around ongoing tasks on-site. Specifically HVAC, electricians, and low-voltage are most likely to have conflicting work in network closets. If they’re working in an IDF, try tackling tasks you have still in the MDF. It’s about optimizing your time on the ground without stepping on other trades’ toes.

This one is simple: show up without the right Personal Protective Equipment and you will be turned around. No exceptions on any professionally managed job site.

Often times, a super will want you to wear a certain color hard hat to identify you as a visitor or engineer.

The baseline required on virtually every active construction site:

Site-specific requirements vary. Certain areas may require respiratory protection. High-noise environments require hearing protection. The Super will brief you on site-specific requirements during your first check-in.

Keep a complete PPE kit in your vehicle or home if you don’t have one.

There is one exception to this: customs and immigration.

If you’re driving to another country and an officer searches your vehicle, having PPE is a certain way to get interrogated for a few hours on whether you’re performing work in the destination country. Not working with visa permissions? Take everything out of your vehicle.

Access and check-in. Most

Schedule your access in advance. The Super manages which trades work in which spaces on which days. By the time tech installs or low voltage cabling gets ran for surveys, the site should be pretty far along. Most likely, there will be furnishing or HVAC work taking place. It doesn’t hurt to check with the Super.

Deliveries don't just show up. You cannot call a supplier and have equipment delivered to an active job site without coordinating it first. There are designated receiving areas, specific delivery windows, and someone who has to sign for everything. Showing up with a pallet of APs and no coordination is a good way to have your gear sitting in a parking lot. Most folks will chose to have their gear delivered to an existing site in the same city if possible.

This matters more than the logistics, because it affects all interactions on site.

Other trades will not know what your equipment does or why it matters. What they need to know is where you are working, what you need from them (clear space, power, conduit placement), and how long you will be in their way.

Respect the work other trades have done. Construction workers take their craft seriously. Do not step on freshly poured concrete. Do not lean your ladder against finished drywall. These are small things that tell everyone on the site whether you are someone they want to help or someone they are going to work around.

You will hear more cursing and crude jokes. There’s no corporate-speak euphemisms. If there’s something on someone’s mind, you’ll hear it verbatim.

Assuming construction will follow your IT project timeline. A construction schedule is a living experiment that ebbs and flows based on weather, inspections, permit delays, and subcontractor availability. Try to have contingency plans.

Leaving equipment on-site unattended. Job sites are high-traffic environments with access from multiple contractors. Leaving gear, cables or a laptop in an unlocked space overnight is how equipment disappears. Lock everything in the IDF or bring it with you. The most common items to lose are hardware (The Home Depot kind). Any drills or tools you bring are immediately useful to others and may be borrowed and left halfway across the site.

Not accounting for dust and debris. Active construction gets dirty. An AP sitting on a folding table will have dust in every port. Protect your equipment. Store it in boxes or the dust bags that came with them. Keep equipment off the floor, and inspect it before installation.

Construction sites have some key differences from offices, but don’t let it stop you. Staying prepared will save you plenty of time and aggravation on-site.

Until next week,
