Direct answer

Cosmetic snagging lists catch paint and fittings; structural engineers look for movement, load-path red flags, waterproofing failures, and safety issues that drive expensive repairs. Hire one for high-value assets, visible cracking, rooftop additions, or when developer responses feel dismissive. Their report is expert opinion—not a court judgment—but it sharpens notices and negotiations.

Key takeaways

  1. 1.Match inspector skills to risk: paint vs structure vs MEP.
  2. 2.Provide drawings and warranty clauses to the engineer.
  3. 3.Convert findings into written notices with deadlines.
  4. 4.Retest after ‘repairs’ rather than trusting patches.

Important terms

Snagging — Defect listing at handover or pre-purchase.

Structural review — Engineer assessment of primary building elements.

MEP — Mechanical, electrical, plumbing systems sometimes needing separate specialists.

Remedial verification — Follow-up visit after claimed repairs.

Detailed answer

Beyond the clipboard

Sales staff may rush handover. An independent engineer can check slab deflections, crack character, balcony drainage falls, and signs of water entry. For condos, distinguish unit defects from common-property issues involving the juristic person.

Registration of ownership remains a DOL matter; snagging protects the physical asset you just titled.

Deliverables to demand

  • Photo-referenced findings
  • Severity ranking
  • Recommended next tests (e.g., leak detection)
  • Suggested contractual notice language themes for counsel

Step-by-step

  1. Book the engineer before the contractual inspection deadline.
  2. Share SPA warranty excerpts and floor plans.
  3. Attend the inspection; keep your own photo set.
  4. Send formal notice through counsel/developer channels promptly.
  5. Require method statements for serious repairs.
  6. Re-inspect before signing satisfaction letters.

Hypothetical example (clearly labeled)

Hypothetical: Hairline cracks are called “normal settling.” An engineer flags a pattern consistent with movement at a bay window. The buyer withholds acceptance of that area until monitoring and remediation plans exist under the SPA.

Illustrative only.

Risks

  • Signing “no further claims” forms under time pressure.
  • Repairs that paint over active leaks.
  • Ignoring common-area structural issues that still affect you.

Practical checklist

  • Engineer booked inside notice windows
  • Documents shared in advance
  • Severity-ranked report received
  • Formal notice sent
  • Repair methods reviewed
  • Re-inspection scheduled

FAQ

Is this only for new builds?

Resales benefit too, especially after renovations.

Can the developer’s engineer be enough?

Independence matters when interests conflict.
