Quality with FransIn shortOn 24 May 2026 a nine-storey building under construction in Balibago, Angeles City (Philippines) collapsed at night and killed 30 people. The city's fact-finding task force has now named the most likely cause: overstressed columns and piles, made worse by structural members added during construction that were not in the original design.
What the task force found
- Overstressed columns and piles were the "highly probable main cause". Their size, number and material properties were not enough for the loads, which led to a progressive collapse.
- Changes during construction. Inspectors found extra steel beams and floor framing that added weight but were not part of the original design.
- Gravity-only design. The columns were designed to resist gravity loads only, without properly considering lateral movement in both directions, in one of the most earthquake-prone countries in the world.
- Construction methods and detailing errors were named as contributing factors.
- Material testing by the public works department is still pending because of a separate investigation.
Separately, the labour department ordered the contractor to pay about ₱11.4 million in wages and fines, including penalties linked to alleged misrepresented safety and first-aid certificates. Criminal complaints have been filed.
Why this matters for QA/QC
Read the findings again and look at them as an inspector. Almost every one is something a working quality system is designed to catch:
| Finding | The control that should have stopped it |
|---|---|
| Beams and framing added that were not in the design | Management of change: no structural change without a revised, approved drawing from the engineer of record. |
| Columns and piles too small for the loads | Design review and checking, and inspection of as-built sizes against approved drawings before every pour. |
| Detailing errors | Rebar inspection against the shop drawings at a hold point, signed by both contractor and consultant. |
| Questionable certificates | Verify certificates at the source, never accept a copy at face value. |
The scariest line in the report is the simplest: things were built that were not on the drawings. On many sites, a client asks for "just one more floor feature" and the steel fixer adds a few beams. Nobody issues a revision, so nobody re-checks the columns below.
Check on your site tomorrow
- Walk one floor with the latest approved structural drawings. Is anything built that is not on them?
- Check your RFI and change log: is every site change backed by an approved revision from the structural engineer?
- Pick one material certificate and verify it with the issuer or the lab.
- Make sure no added load (tanks, pools, plant, extra slabs) goes ahead without a structural check.
