When you're hiring a cell tower contractor, their portfolio of past projects tells you almost everything you need to know about their capabilities, safety record, and reliability. Asking the right questions about previous work isn't just due diligence—it's how you avoid costly mistakes, delays, and compliance issues that could leave your site incomplete or non-operational. Here's how to evaluate a contractor's experience systematically.
Why Past Projects Matter More Than You Think
A contractor's track record directly impacts your timeline and budget. Someone with 50 completed tower installations across different terrain types and climates will handle your project differently than someone with five projects, all in flat urban areas. Past projects reveal whether they've navigated FCC regulations, FAA lighting requirements, environmental assessments, and local permitting—all real hurdles that inexperienced crews stumble over.
More importantly, past projects show structural integrity outcomes. A tower installed incorrectly five years ago might still be standing, but improper grounding, inadequate foundation work, or substandard rigging can cause catastrophic failure during wind events or when additional antennas are mounted later.
Specific Questions to Ask About Previous Work
Start by asking for three to five completed tower projects within the last 24 months. Require a mix: at least one ground-mounted tower, one rooftop installation if relevant to your needs, and one in similar geographic or climate conditions to your site.
For each project, dig into these details:
- Tower type and height — Did they install 80-foot monopoles, 150-foot lattice towers, or rooftop-mounted small cells? Height and type affect engineering complexity.
- Site conditions — Ask about soil composition, access challenges, weather during installation, and whether the original timeline held.
- Antenna and RF load — How many carriers were served? What was the total antenna weight and RF output? This tells you if they've handled your capacity requirements.
- Permitting and compliance — Did they manage the FCC filing, FAA notification (if over 200 feet), and local zoning approvals? Did inspections pass on first submission?
- Safety record — Request the number of recordable incidents, near-misses, or OSHA citations during those projects. Zero incidents is the only acceptable answer.
- Timeline performance — Get the planned duration versus actual completion date. Delays often signal poor planning or understaffing.
- Cost overruns — Ask directly if the project came in on budget. If not, why? (Weather delays are common; poor estimating is a red flag.)
- Client references — Request the site manager or network engineer from at least two projects. A contractor should be proud to connect you with past clients.
Red Flags to Watch For
Contractors who hedge on project details, decline to provide references, or only show you photos (not certified completion reports) are signaling something. Legitimate tower work includes documentation: as-built drawings, RF engineering reports, foundation certifications, and safety inspection checklists. If they can't produce these, they likely didn't.
Also note vague answers about permitting. If a contractor says "we handle it" without walking through the FCC or local process, they're either new to the work or cutting corners. Cell tower projects often sit in permitting limbo for 4–12 weeks; a contractor should explain exactly what they did to expedite approval on past jobs.
Verifying Credentials Beyond Projects
Past projects should back up certifications. Look for NATE (North American Tower Climber Association) membership, OSHA 30 certification, and working-at-heights qualifications for crew members. Ask how many of their climbers hold current NATE certifications and when they last completed safety recertification.
Insurance is non-negotiable. Require proof of $2–5 million general liability coverage and workers' compensation. Ask how many claims they've had in the past three years—contractors with frequent claims indicate either bad luck or unsafe practices.
Comparing Multiple Contractors
Once you've vetted 2–3 contractors and collected details on their past projects, create a simple comparison sheet: contractor name, project types completed, total projects in past 24 months, safety record, average timeline performance, and reference availability. You'll quickly spot who's genuinely experienced and who's overstating their capability.
If you're comparing multiple contractors across your region, Mercoly lets you find and evaluate trusted cell tower construction providers side-by-side, with verified past project data and customer feedback all in one place.
Frequently Asked Questions
Q: How many past projects should a contractor have completed before I hire them? For new construction or major upgrades, look for at least 10–15 projects of similar scope in the past three years; for maintenance or small-scale work, 5–7 recent projects is acceptable.
Q: What should I do if a contractor refuses to provide references? Do not hire them—this is an absolute dealbreaker and suggests they have something to hide, whether safety issues, missed deadlines, or quality problems.
Q: Can I visit a past project site to inspect the work? Yes, and it's worth doing for high-stakes projects; ask the contractor for permission to contact the site owner and arrange a brief site visit to visually confirm workmanship and structural quality.
