QLASSIC vs defect inspection (and CONQUAS): What inspectors should tell buyers
Thursday morning, Penang condo key collection. The buyer slides a photocopied QLASSIC certificate across the table — CIS 7 score 76%, stamped and signed by CIDB assessors. "The developer says the building passed. Do I still need a defect inspection?"
Or: Sunday handover at a Sengkang BTO, Singapore. The agent taps a brochure showing CONQUAS 90+ on the project page. "BCA certified, already inspected. Why pay for another report?"
Your first answer shapes whether they book — or walk away with a dangerous misconception.
A QLASSIC score or CONQUAS band is a project-level workmanship assessment based on sampling. It is not a unit-by-unit vacant possession defect checklist. It does not document the specific cracks, hollow tiles, or leaking taps in your client's unit. It does not produce a coded PDF the buyer can use when the Defect Liability Period (DLP) notice is due.
This guide is for Malaysian and Singaporean property defect inspectors who need a clear, professional script to explain the difference — without lecturing or sounding defensive — and still ship the handover evidence pack buyers need for the DLP.
What QLASSIC (Malaysia) and CONQUAS (Singapore) actually are
Both are project assessment frameworks used by developers, contractors, and industry bodies to measure construction workmanship at the development level. They shape how the industry talks about quality — but they are not buyer-facing unit defect reports.
QLASSIC (Malaysia / CIS 7)
QLASSIC (Quality Assessment System in Construction) — and its CIS 7 (Construction Industry Standards 7) successor — is a project workmanship scoring system maintained by the Construction Industry Development Board (CIDB, Malaysia). Assessors visit a project at near-completion, sample selected units and common areas, check compliance against a standardised checklist, and assign a percentage score (e.g. 65%, 78%, 82%) to the entire development.
Key facts for inspector reference:
- Scope: project-level workmanship; sampling only (not every unit)
- Assessors: CIDB-accredited professionals
- Timing: typically near practical completion or after CCC (Certificate of Completion and Compliance)
- Who pays: developer commissions the assessment (or mandated by state / project type)
- Output: a score certificate + project report; not a unit-specific defect list for buyers
- Buyer misconception: "QLASSIC passed" ≠ "my unit has no defects"
Industry commentary — including MBAM (Master Builders Association Malaysia) guidance — stresses that QLASSIC / CIS 7 is not a substitute for a unit-level vacant possession defect inspection. A high QLASSIC score means the sampled work met industry benchmarks on assessment day; it does not guarantee that your client's unit is free of hollow tiles, cracks, ponding, or uneven doors.
CONQUAS (Singapore / BCA)
CONQUAS (Construction Quality Assessment System) is Singapore's project-level quality scoring framework, administered by the Building and Construction Authority (BCA). Assessors evaluate sampled work across structural, architectural, and M&E (mechanical & electrical) categories, and assign a band or score to the development.
Key facts for inspector reference:
- Scope: project-level quality; sampling-based assessment
- Assessors: BCA-accredited teams
- Timing: typically completed before TOP (Temporary Occupation Permit) or CSC (Certificate of Statutory Completion)
- Schemes: tiered bands exist (e.g. CONQUAS Star for high-rise residential); some private residential projects participate
- Who pays: developer engages the assessment
- Output: a project score or band certificate; not a unit-specific handover checklist
- Buyer misconception: "CONQUAS 90" ≠ "no defects in my unit at key collection"
The project score is a development-wide average derived from samples. It does not tell the buyer where to look for hollow plaster in Bath 2, whether the balcony drains properly, or if the wardrobe doors are misaligned. That information lives in a unit defect inspection — the private evidence pack you produce for the buyer's DLP process.
What inspectors sell (and what QLASSIC/CONQUAS does not deliver)
Your service is different. You are not re-scoring the development. You are documenting this specific unit for this specific buyer, so they have professional evidence when the developer asks for a defect notice during the DLP.
| Your unit defect inspection | QLASSIC / CONQUAS |
|---|---|
| Unit-specific (Block 3A, #08-12) | Project-wide (entire development) |
| Every room, every surface in the sold package | Sampled units and common areas |
| Buyer commissioning (private hire) | Developer commissioning (or mandated) |
| Coded photo evidence (A01, B03…) + legends | Checklist + score certificate |
| Zoomable PDF for DLP notices | Project report for industry / marketing |
| Includes optional socket / spirit / ponding | Workmanship benchmarks only |
| Delivered at or after vacant possession | Often before VP or TOP |
If the buyer only relies on QLASSIC / CONQUAS and skips a unit inspection, they arrive at the DLP with no photos, no codes, no legend, and no evidence — just a vague memory of "something felt wrong in the kitchen" six weeks ago.
Malaysia and Singapore framing — same ops, different words
The core answer is identical in both markets; only the local terminology and framing change.
Malaysia (QLASSIC / CIS 7)
What to say:
"QLASSIC / CIS 7 is an excellent industry standard, and it tells us the development met workmanship benchmarks when CIDB sampled it. What it does not provide is a room-by-room defect record for your unit — Block [X], Level [Y], Unit [Z] — with photo codes, legends, and annotation that you can use when the developer asks for a defect notice during the DLP.
MBAM and industry guidance make this clear: a QLASSIC score is not a substitute for your unit's VP defect inspection. The score is about the project; the coded PDF we produce is about this unit, so you have professional evidence ready when the DLP process starts."
Common follow-up: "But the developer gave me a defect form at key collection. Isn't that enough?"
Answer:
"That form is useful for immediate rectification. A professional inspection adds: (1) photo evidence with stable codes (A01, A02…) so you can reference specific defects weeks later; (2) a zoomable PDF that survives forwarding and pinch-zoom during the DLP; (3) optional socket / spirit / water-ponding pages when you add those checks to the package. The developer form documents what you report on the day. Our PDF documents the evidence you reuse later. See how buyers use a defect inspection PDF during the DLP."
Singapore (CONQUAS)
What to say:
"CONQUAS is BCA's quality framework for the development, and a high score is a strong signal that the project met industry standards. What CONQUAS does not do is create a defect list specific to your unit — your block, your level, your floor plan — with photo evidence, codes, legends, and annotation that you can use for Notice of Defects or the DLP process.
CONQUAS is about project-wide workmanship sampling. A unit defect inspection is about documenting this unit so you have professional evidence when you need to report defects to the developer or management later."
Common follow-up: "Do I need a defect inspector if the BTO already has CONQUAS?"
Answer:
"Yes, if you want a professional evidence pack. BTO projects often publish CONQUAS bands, which is excellent for project credibility. A unit inspection is still your private record — photo evidence, codes, legends, optional test pages — so you have reusable documentation during the defects liability period. CONQUAS tells you the project met BCA benchmarks. Our PDF tells you what is in your unit on handover day."
Side-by-side: Malaysia and Singapore
| Ops item | Malaysia framing | Singapore framing |
|---|---|---|
| Project assessment system | QLASSIC / CIS 7 (CIDB) | CONQUAS (BCA) |
| Assessment scope | Sampled units and work packages | Sampled work across structural / architectural / M&E |
| Typical timing | Near completion or after CCC | Before TOP or CSC |
| Buyer VP event | Vacant possession / key collection after CCC | Notice of Vacant Possession / key collection after TOP/CSC |
| DLP window (commonly discussed) | 24 months from VP (HDA Schedule G/H for qualifying housing) | 12 months from NVP (standard Housing Developers Rules forms) |
| Unit defect inspection purpose | Coded evidence for DLP notice (buyer's private hire) | Coded evidence for Notice of Defects / DLP (buyer's private hire) |
| What QLASSIC / CONQUAS does not give the buyer | Room-by-room photo codes, legends, zoomable PDF | Room-by-room photo codes, legends, zoomable PDF |
Your PDF spine stays the same in both markets: cover, property info (if package includes it), photo grids, legends, disclaimer, optional socket / spirit / ponding pages. Only the buyer language and exact DLP framing change.
What still belongs in your coded PDF (whether QLASSIC or CONQUAS exists)
A project score does not replace any part of a professional unit defect inspection. You still document and deliver:
- Cover fields — unit identity (block, level, unit number, SPA / key collection spelling), client name, inspection date, property address
- Property information page (if package includes it) — occupancy status, inspection purpose, property type, furnishing status, weather condition, attendees, land size (landed properties)
- Room-ordered defect evidence — photo grids per area (A = Foyer, B = Living, C = Kitchen…) with automatic codes (A01, A02, B01…), annotations on fragile shots (hairline cracks, damp edges, lippage), and full-resolution photos when tier or client package requires it
- Legend table per area — match codes to issue descriptions (A01: Wall crack near switch — living room north; A02: Hollow tile sound — foyer entrance left), group honest ranges (B03–B09: Kitchen cabinet door misalignment), fill every row before Generate
- Optional test pages (only when sold) — socket / electrical points with reference table (Malaysia), spirit level results, water ponding start/end photos + pass/fail statement
- Disclaimer and certification — inspector name, cert/IC, date, signature box, optional company stamp box (per your firm's SOP)
The QLASSIC or CONQUAS score might appear in marketing copy or the developer handout. It does not appear in your PDF unless the buyer specifically asks you to note it in remarks — and even then, clarify it is a project score, not a unit inspection.
What to avoid (no invented claims; no legal advice)
Do not:
- Tell the buyer "QLASSIC / CONQUAS is meaningless" — it is a respected industry standard; you are clarifying scope, not dismissing the system
- Invent statutory requirements ("the law says you must inspect every unit") — there is no MY or SG statute forcing buyers to hire private inspectors; your value is professional evidence, not invented legal mandates
- Promise legal outcomes ("with our PDF you will win the dispute") — you document defects; you are not the buyer's lawyer or tribunal expert
- Suggest QLASSIC / CONQUAS is "just marketing" — it is an established industry assessment; the buyer confusion is about what it covers, not whether it exists
- Claim your inspection "replaces" the developer handover process — your PDF complements the SPA / VP / key collection steps; it does not substitute developer obligations
Keep the tone factual and professional: "QLASSIC / CONQUAS is about project workmanship sampling. A unit defect inspection is about your unit's evidence for the DLP."
Quick script for the field (ops language, not a lecture)
Buyer: "The developer says QLASSIC passed. Do I still need this?"
Inspector (Malaysia): "QLASSIC is excellent for the project. It does not give you a room-by-room defect record with photo codes and legends for this unit. That is what we produce — so you have professional evidence ready when the developer asks for a defect notice during the 24-month DLP window. Industry guidance, including from MBAM, confirms QLASSIC is not a substitute for your unit inspection."
Inspector (Singapore): "CONQUAS tells us the project met BCA workmanship standards. It does not document the specific defects in your unit — Block [X], #[Y]-[Z] — with photo codes, legends, and annotation. That is what a unit inspection delivers: professional evidence you reuse during the defects liability period. CONQUAS is about the development; our PDF is about this unit."
Buyer: "But it's extra cost."
Inspector: "Yes, it is. What you are paying for is not a second project score — you are paying for a coded evidence pack (photos, legends, optional test pages) that still works six weeks later when you write a defect notice. Without it, the DLP conversation becomes memory and vague descriptions. With it, you have stable codes and zoomable evidence the developer can act on. See how much to charge for defect inspection and how buyers use a defect inspection PDF during the DLP."
Where software helps (same PDF spine, whether QLASSIC or CONQUAS is nearby)
You still decide what is a defect and how to frame the walk. Software decides whether the evidence pack is reusable — codes stable, legends filled, uploads complete, PDF zoomable.
Defiq Inspect is built for Malaysia and Singapore VP / handover workflows: offline-first capture with area + issue tags, automatic coding, photo annotation (circle, arrow, text), branded PDF spine (cover, property info, grids, legend, disclaimer, optional socket / spirit / ponding pages) aligned to QLASSIC- and CONQUAS-shaped report expectations, and a Generate button that waits until uploads finish so the file the buyer opens in the DLP is not a thumbnail fiction.

QLASSIC and CONQUAS structure workmanship language in MY and SG. Your report structure mirrors that language (cover, property block, section-ordered grids, legends, disclaimers, test pages) — not because you re-score the project, but because buyers and developers in both markets expect a professional handover PDF to follow the same formal spine.
Soft CTA — the unpaid gap is the "QLASSIC passed, do I need you?" conversation. Software encodes the answer: yes, because a project score is not a unit evidence pack. See how it works.
Frequently asked questions
Is QLASSIC a defect inspection?
No. QLASSIC (and its CIS 7 successor) is a project-level workmanship scoring system in Malaysia. CIDB assessors sample selected units and common areas, check compliance against standardised benchmarks, and assign a percentage score to the development. It does not produce a unit-specific defect list with photo codes, legends, and annotation. A professional unit defect inspection documents your client's unit for the DLP — room by room, code by code, evidence that still works six weeks later.
Does CONQUAS replace a unit VP inspection?
No. CONQUAS (Singapore / BCA) is a project-wide quality assessment based on sampling. A high CONQUAS band means the development met BCA workmanship standards when assessed. It does not document the specific defects in your client's unit at key collection. A unit defect inspection produces coded photo evidence (A01, B07…), filled legends, optional test pages (socket / spirit / ponding), and a branded PDF the buyer can reuse during the defects liability period. CONQUAS is about the project; the defect PDF is about this unit.
Do buyers in Malaysia need a defect inspection if the project has QLASSIC CIS 7?
Yes, if they want professional evidence for the DLP. A QLASSIC or CIS 7 score tells them the development met CIDB benchmarks on project assessment. It does not give them a room-by-room defect record with photo codes and legends for their unit. Industry commentary — including MBAM guidance — confirms that QLASSIC is not a substitute for a unit VP defect inspection. The buyer still needs a coded PDF to write a defect notice weeks after vacant possession.
Should inspectors mention QLASSIC or CONQUAS in the defect report?
Not in the main PDF unless the buyer asks and you clarify scope in a remarks section. QLASSIC and CONQUAS are project-wide workmanship assessments; your PDF is a unit-specific defect list. Mixing the two creates confusion — buyers might think your report "re-scores" the project, when your job is to document this unit's evidence for the DLP. If the buyer insists on a reference, add a disclaimer note: "QLASSIC / CONQUAS is a project assessment system and does not replace a unit-level defect inspection."
How do I explain QLASSIC vs unit inspection to a buyer in simple terms?
"QLASSIC is like a school giving the entire year group a grade. A unit inspection is like your child's individual report card. The year-group grade tells you the school met standards. The report card tells you what your child scored in every subject. QLASSIC tells you the project met CIDB benchmarks. Our PDF tells you what defects exist in your unit — with photo codes, legends, and evidence you can use during the DLP."
How do I explain CONQUAS vs unit inspection to a buyer in simple terms?
"CONQUAS is BCA's grade for the entire project — based on sampling selected work. A unit inspection is your private record for this unit — your block, your floor, your specific defects — with photo codes, legends, and annotation. CONQUAS tells you the development met quality benchmarks. Our PDF tells you what your unit looks like on handover day, so you have professional evidence ready when you write a defect notice."
Does a QLASSIC or CONQUAS score mean I can charge less?
No. The project assessment and your unit inspection serve different purposes. A high QLASSIC or CONQUAS band does not reduce the field work, coding discipline, legend writing, or PDF assembly time. If anything, buyers with QLASSIC / CONQUAS nearby often need more client education (this guide) before they understand why your service is not redundant. Price the professional handover package — standard walk + coded PDF + optional test pages + optional multi-trip / rectification review — not the developer marketing copy. See how much to charge for defect inspection.
Should every defect report include property information and socket / ponding pages?
Property information (occupancy status, property type, furnishing, weather, attendees, land size) is optional but common on formal handover packs — especially when the buyer language or project profile expects a structured report. Socket / spirit / ponding pages are only required when those checks were part of the sold package. If the package was photo-and-legend only, say so in the quote and keep the PDF honest. Empty or half-filled test pages weaken the DLP file.
Does Defiq Inspect support QLASSIC- and CONQUAS-aligned report structures?
Yes. Defiq Inspect is built for Malaysia and Singapore VP / handover workflows. The PDF spine follows the same formal structure buyers and developers in both markets expect: cover, property info (optional), section-ordered photo grids, legend tables, disclaimer / certification, optional socket / spirit / ponding pages. Report templates match QLASSIC- and CONQUAS-shaped expectations (professional layout, stable coding, filled legends) without claiming to re-score the project. Team plans add multi-inspector area claiming so large units do not double-book the same bathroom under conflicting codes.
QLASSIC and CONQUAS shape workmanship language in Malaysia and Singapore. They are respected industry standards — and they are not unit defect inspections.
A project score tells the buyer the development met benchmarks when sampled. Your coded PDF tells the buyer what defects exist in this unit — with photo evidence, stable codes, filled legends, optional test pages, and zoomable resolution — so the file still works six weeks later when the DLP notice is due.
