Structural Analysis & Reinforcement
P.Eng-backed structural analysis and physical reinforcement so an existing tower can safely carry new loads - and stand up to review under CSA S37.
- P.Eng analysis to CSA S37
- As-built verified by a real climb, not old drawings
- We do the reinforcement, not just the report
- Documentation carriers and co-locators accept
Before you hang another antenna, add a dish, or take on a co-locator, one question has to be answered: can the tower actually carry it? Broadband Tower Services pairs a climbing assessment of the real structure with P.Eng analysis, then carries out the reinforcement the numbers call for - so the upgrade is safe, compliant and signed off.
Why it matters
Every tower is engineered for a specific load - so much antenna area, so much weight, at so much wind and ice. Add to that without checking and you erode the safety margin the structure was designed around. New loading, a co-location, or simply an old tower that's never been re-rated all trigger the same need: a structural analysis against the current Canadian standard, CSA S37, before anything goes up.
What the analysis covers
- As-built verification - a climbing inspection captures the structure as it really is today: member sizes, condition, corrosion, existing appurtenances and any prior modifications. Drawings are often decades old or missing; the analysis has to start from reality.
- Load modelling - the existing plus proposed loading is modelled against CSA S37 wind and ice for the site, leg by leg and connection by connection.
- The verdict - a P.Eng stamps whether the tower passes as-is, passes with reinforcement, or can't safely take the load - with the reinforcement defined where it's needed.
The reinforcement
When the analysis calls for strengthening, we do the physical work: leg and bracing reinforcement, gusset and connection upgrades, foundation and guy-anchor improvements, and member replacement where corrosion has taken its toll. Because we climb our own jobs, the crew that assessed the tower is the crew that reinforces it - no handoff, no relearning the site.
The deliverable
You get a P.Eng-stamped structural report documenting the analysis, the loading and the conclusion, plus an as-built record of any reinforcement carried out - the documentation a carrier, co-locator or regulator expects before the new load goes into service.
FAQ Common questions
Good to know
Why do I need a structural analysis to add an antenna?
A tower is engineered for a specific load. Adding antennas, dishes or a co-locator changes the wind and ice loading, and going past what the structure was designed for erodes its safety margin. A CSA S37 analysis confirms the tower can carry the new load - or defines the reinforcement that lets it.
Do you provide a P.Eng stamp?
Yes. We work with a professional engineer who stamps the structural assessment per CSA S37, so the analysis stands up to carrier, co-locator and regulatory review.
What if drawings for the tower don't exist?
That's common on older towers. We start with a climbing inspection to capture the structure as-built - member sizes, condition and existing loading - so the analysis is based on what's really there, not on missing or outdated paper.
Can you do the reinforcement too, not just the report?
Yes - reinforcement is core work for us. The same certified crew that assesses the tower carries out leg, bracing, connection, foundation and anchor strengthening, then documents the as-built result.
