Pre-purchase assessment — find the unauthorised works before you sign the SPA.

Buying a property in Singapore? Three things kill the deal at conveyancing: unauthorised mezzanines, illegal extensions, and structural defects from past A&A. CVC Engineers inspects the property, flags every compliance issue, and gives you a lawyer-ready report — with the regularisation cost priced — before you commit.

Why your conveyancing lawyer wants this report.

Property lawyers can read a title search. They cannot tell whether a mezzanine in the loft was approved by BCA. CVC Engineers fills that gap — a registered Professional Engineer's independent compliance assessment, written so a lawyer can rely on it.

Most pre-purchase deal failures in Singapore happen at the buyer's lawyer's compliance check — usually 2–4 weeks after the Option to Purchase is exercised. The lawyer asks for as-built drawings and BCA approvals; the seller can't produce them; the buyer either walks away or negotiates a price reduction.

CVC Engineers' pre-purchase assessment runs before you exercise the OTP. The deliverable is a written report covering:

  • Compliance check — every visible structural element vs. BCA approved drawings
  • Unauthorised works register — identified items, severity grading, regularisation feasibility
  • Structural defect map — cracks, settlement, water damage, façade integrity
  • Regularisation cost estimate — itemised, with timeline
  • Risk grade — Green / Amber / Red recommendation
  • Lawyer's annex — short-form summary your conveyancing lawyer can attach to the SPA

When to commission:

  • Pre-OTP — best timing. You haven't paid the option fee, walking away costs nothing.
  • Post-OTP, pre-SPA — common. You have ~14 days to discover problems; we can rush.
  • Selling side — sellers commission us to clear the file before listing, removing buyer-side surprises and supporting the asking price.
  • Bank financing — some banks now require a structural compliance letter for older landed properties before approving the loan.
  • Insurance underwriting — high-value heritage properties may require structural certification before policy issue.

Properties we commonly assess: landed homes (especially those with rear A&A), older condominiums (1980s–2000s), HDB flats with renovation history, conservation shophouses, commercial units with prior fit-out, and any property with a known unauthorised works dispute.
