What Is a Condition Survey?
A building condition survey is a systematic assessment of a building fabric and services to establish current condition, identify defects, estimate remaining useful life of components, and project future maintenance and capital expenditure. It is the foundation of evidence-based building management.
Survey Types
| Type | Scope | When to Use | Standard |
|---|---|---|---|
| Level 1 — Walk-through | Visual inspection only, no intrusive testing, general condition overview | Annual review, portfolio screening, initial assessment | RICS Level 1 |
| Level 2 — Condition Survey | Detailed visual inspection, condition grading, estimated costs, lifecycle projections | Pre-lease, pre-purchase DD, capital planning, 5-year review | RICS Level 2, ASTM E2018 |
| Level 3 — Structural/Diagnostic | Intrusive testing, opening up, specialist testing (concrete, steel, facades) | Suspected structural issues, post-incident, major refurbishment planning | RICS Level 3 |
| PCA — Property Condition Assessment | US standard: systematic assessment per ASTM E2018, identifies immediate repairs and CAPEX forecast | Commercial transactions, due diligence, portfolio assessment | ASTM E2018 |
Condition Grading
| Grade | Condition | Action | Budget Impact |
|---|---|---|---|
| A | Good / As new | Routine maintenance only | Included in OPEX |
| B | Acceptable / Minor deterioration | Planned maintenance, monitor | Included in OPEX |
| C | Poor / Major deterioration | Planned replacement within 1-3 years | CAPEX required |
| D | Failed / Urgent | Immediate repair or replacement | Emergency CAPEX |
What a Condition Survey Covers
- Building fabric: structure, roof, external walls, windows, doors, internal finishes, floors
- Mechanical services: HVAC, plumbing, drainage, fire suppression, lifts, generators
- Electrical services: main switchgear, distribution, lighting, emergency lighting, fire alarm, security
- External works: car parks, landscaping, drainage, boundary walls, access roads
- Compliance items: fire safety, accessibility, asbestos, electrical certification
Using Condition Data
- Facility Condition Index (FCI): Total deferred maintenance cost divided by current replacement value. FCI below 5% = good. FCI 5-10% = fair. FCI above 10% = poor. FCI above 30% = consider replacement.
- 5-year CAPEX forecast: Project replacement costs by year based on remaining useful life and condition grade.
- Lifecycle costing: Compare repair vs replace decisions using total cost of ownership over remaining building life.
- Budget justification: Condition data provides evidence-based justification for maintenance and capital budgets.
When to Commission a Survey
- Pre-acquisition or pre-lease (due diligence)
- Every 3-5 years for capital planning
- After a major incident (fire, flood, structural event)
- Before major refurbishment (to scope works accurately)
- Change of building management company
- Insurance or lender requirement

Insights & Guidance
- 4 survey types: Level 1 (walk-through), Level 2 (detailed condition), Level 3 (structural/diagnostic), PCA (ASTM E2018 for transactions).
- Condition grading A-D: A (good/routine), B (acceptable/monitor), C (poor/replace 1-3 years), D (failed/immediate).
- Facility Condition Index (FCI): deferred maintenance / replacement value. Below 5% good, 5-10% fair, above 10% poor.
- Commission a survey every 3-5 years for capital planning, before any acquisition/lease, and after major incidents.
- Condition data transforms maintenance from reactive spending to evidence-based capital planning.
Without condition data, maintenance budgets are guesses. Condition surveys provide the evidence base for capital planning, replacement scheduling, and budget justification. They are essential for due diligence and transaction decisions.
- No baseline — without a condition survey, deterioration is discovered only when things fail.
- Underestimated CAPEX — buildings acquired without condition surveys often reveal unexpected capital needs.
- Wrong survey level — a Level 1 walk-through cannot identify structural issues requiring Level 3.
