If your council, landlord, strata manager or insurer has asked for an engineer’s certificate on your shop awning, you are probably wondering what it involves, how long it takes and what happens if the engineer finds a problem. This guide walks through the whole process in plain English, based on the method structural engineers in NSW follow for suspended street awnings, and explains where an awning contractor like us fits in at each stage.
Why Councils Ask for Engineering Certification
Suspended street awnings hang over public footpaths, so a failure can injure people walking underneath. After a fatal awning collapse in Balgowlah, a coroner’s inquest found that there had been 17 awning collapses in NSW since an earlier fatal collapse in Bathurst in 1998. The NSW Government responded with Planning Circular BS 13-001, which reminds councils and owners of a few key points:
- The building owner is responsible for the awning, even though it sits over a council footpath.
- Awnings more than 10 years old are more likely to fail and should be inspected by a professional engineer.
- Councils have the power to issue orders requiring an owner to repair or remove an unsafe awning.
That is why so many Sydney councils now send awning inspection letters and ask owners for a certificate from a structural engineer. If you have already received a formal notice, our guide to council awning safety orders explains your options.
What the Engineer Is Actually Checking
Most street awnings look solid from the footpath. The risk sits in parts you cannot see. Engineers in NSW follow guidance from the Association of Consulting Structural Engineers (Practice Note 18) when assessing suspended awnings, and the main items on their list are:
- Tie rods and hanger rods: corrosion often starts where the rod enters the wall or the awning frame, hidden behind linings and flashings. Read more in our guide to rusted tie rods.
- Anchor plates and wall fixings: in older buildings the rods are often anchored into soft lime mortar brickwork that has weakened over time.
- The parapet and wall: the wall has to carry the load from the rods, and old parapets are not always strong enough.
- The awning frame: rusted steel beams, rotted timber and failed connections.
- Water and debris: ponding water, blocked gutters and hail build up add weight the awning was never designed for.
- Wind uplift: strong winds can push an awning upward, which rods alone do not resist.
- Shared rods: in older shopping strips, one tie rod sometimes supports two neighbouring awnings, so one owner’s problem becomes the next owner’s problem too.
Engineers also compare the awning against current loading standards (AS/NZS 1170). Many older awnings were designed to lighter loads than today’s standard, so an awning can be “as built” and still fall short.
The 5 Stages of Awning Engineering Certification
Practice Note 18 sets out a staged process. Not every awning needs every stage, but this is the full path from first inspection to signed certificate.
Stage 1: Initial Visual Inspection
The engineer inspects the awning from the footpath and, where safe, from a ladder or the floor above. They note visible rust, sagging, cracked fixings, water damage and anything that suggests a hidden problem. For a newer awning in good condition this may be enough to certify. For older awnings it usually leads to stage 2.
Stage 2: Opening Up for a Hidden Inspection
Because the critical connections are hidden, the engineer often needs parts of the awning opened up: soffit linings removed, flashings lifted and the rod connections exposed at the wall and the frame. This is where an awning contractor comes in. We can prop the awning safely, open up the areas the engineer nominates and arrange any footpath approvals the work needs, so the engineer can see exactly what is there.
Stage 3: Engineer’s Report and Repair Instructions
The engineer then writes a report. If everything is sound, it says so. If not, it sets out what needs to be repaired or replaced, such as new tie rods, new anchor plates, frame repairs or strengthening of the wall. This report is what you take to contractors for quotes and, if needed, to council.
Stage 4: Repairs and Final Inspection
The repairs are carried out to the engineer’s instructions, and the engineer comes back to inspect the work before it is closed up. This step matters: once the linings go back on, nobody can see the new connections, so the engineer needs to check them while they are exposed. We coordinate the timing so the engineer sees the work at the right point, then make good the linings, flashings and paint.
Stage 5: Certification
Once satisfied, the engineer issues a certificate stating the awning is structurally adequate. Keep a copy with your building records and send one to council if they asked for it. Practice Note 18 recommends re-inspection about every 5 years, so put a reminder in the diary.
How Long Does It Take?
A simple certification on a sound awning can be done in a single visit. Where opening up and repairs are needed, allow several weeks across the engineer’s inspections, quoting, any council approvals and the repair work itself. If council has issued a deadline, start early and keep council informed of progress, as they are usually more flexible when an owner can show the process is under way.
What If the Engineer Finds a Problem?
Do not panic. Most problems found during certification are fixable, and finding them early is far cheaper than dealing with a failure. Common outcomes are replacing corroded tie rods and anchor plates, repairing or replacing frame members, or in some cases replacing the awning altogether. Our guide on whether to repair or replace a damaged awning covers how to weigh up the options. If the engineer considers the awning unsafe, it may need to be propped straight away, which we can arrange as an emergency repair.
Tips for Owners and Strata Managers
- Use a structural engineer with experience in suspended street awnings, not just general building inspections.
- Ask for the report to include clear repair instructions that a contractor can price.
- Have your awning contractor and engineer talk directly. It saves time on site and avoids repeat visits.
- Keep every report and certificate. They help with insurance, sales and future council requests.
- For strata buildings, add awning inspections to the capital works plan. Our strata and commercial awning compliance guide has more detail.
Certification is just as important on new work. When we build commercial awnings, we coordinate the engineering and sign off from the start.
