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.Match inspector skills to risk: paint vs structure vs MEP.
- 2.Provide drawings and warranty clauses to the engineer.
- 3.Convert findings into written notices with deadlines.
- 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.

Comparison table

|---|---|---|
| Handover agent checklist | Cosmetics | Structure |
| Structural engineer | Movement, load risks | Fine interiors taste |
| Specialist leak detector | Water paths | Legal strategy |
| Counsel | Notice rights | Technical causation |
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.
