The Dutch standard for objective condition measurement of building and installation components.
NEN 2767 is the most widely adopted condition assessment methodology in the Netherlands and increasingly used across Europe. It provides a transparent, reproducible framework that turns subjective inspections into objective, comparable data — forming the foundation for predictive maintenance and lifecycle planning.
What is NEN 2767?
NEN 2767 is a Dutch methodology for objectively measuring the physical condition of building and installation components using a standardized 1-to-6 rating scale, defect classification system, and weighted scoring algorithm.

How NEN 2767 Works
NEN 2767 decomposes a building into a hierarchy of elements (e.g., roof, facade, HVAC) and sub-elements. Inspectors record individual defects for each element, classifying each by severity, extent, and intensity. The standard then combines these defect scores into a single condition rating per element using a weighted algorithm. Because every inspector follows the same decision tree, results are reproducible across teams and time — making NEN 2767 the language of condition data in Dutch asset management.
The 6-Point Rating Scale
Each building element receives a condition score from 1 (excellent) to 6 (very poor). The score drives maintenance priority and budget allocation.
| Rating | Condition | Description |
|---|---|---|
| 1 | Excellent | No defects. The element functions as new and requires no maintenance action. |
| 2 | Good | Minor defects with negligible impact. Normal aging visible but no maintenance needed yet. |
| 3 | Fair | Visible defects of limited significance. Maintenance can be planned within normal cycles. |
| 4 | Moderate | Clearly visible defects that will worsen. Maintenance should be scheduled in the short term. |
| 5 | Poor | Serious defects impacting functionality. Urgent maintenance required to prevent failure. |
| 6 | Very Poor | Critical condition — element has failed or is about to fail. Immediate action necessary. |

Severity, Extent & Intensity
Every observed defect is classified along three dimensions. The combination determines its weighted impact on the overall condition score.
Severity
How critical is the defect type? Severity is fixed per defect category in the standard — a structural crack always has higher severity than paint discoloration, regardless of how much of the element is affected.
Extent
What percentage of the element is affected? Extent is recorded in predefined ranges: <2%, 2–10%, 10–30%, 30–70%, and >70%. This ensures consistent estimation across inspectors.
Intensity
How far has the defect progressed? Intensity captures the degree of development: initial stage, advanced, or end stage. A small but fully developed crack scores higher than a large but superficial stain.
Digitize NEN 2767 with Geocadra
Traditional NEN 2767 inspections rely on paper forms and spreadsheet calculations. Geocadra replaces that workflow with a structured digital process.
Structured inspection forms
Pre-built NEN 2767 form templates with drop-downs for severity, extent, and intensity. Inspectors select — never free-type — ensuring consistent defect classification in the field.
Photo-linked defect records
Every defect record is tied to geotagged photos and a map location. Reviewers see exactly where each defect sits on the building, not just a description in a spreadsheet row.
Automatic condition scoring
Geocadra calculates the NEN 2767 weighted condition score automatically as inspectors record defects — no post-processing in Excel needed.
Multi-year comparison
Track condition scores over time for every element. Visualize degradation trends to shift from reactive repairs to predictive maintenance planning.
Frequently Asked Questions
What is NEN 2767?
NEN 2767 is a Dutch standard that provides a methodology for objectively assessing the physical condition of building and installation components. It uses a 6-point rating scale (1 = excellent, 6 = very poor) and a structured defect classification system to produce comparable, reproducible condition data.
Who uses NEN 2767?
NEN 2767 is widely used by property managers, housing associations, municipalities, and facility managers in the Netherlands. It is also gaining adoption across Belgium, Germany, and other European countries for portfolio-level condition monitoring.
What is the difference between NEN 2767-1 and NEN 2767-2?
NEN 2767-1 covers the condition assessment methodology itself — the rating scale, defect classification, and scoring algorithm. NEN 2767-2 provides guidance on listing and decomposing building elements into inspectable sub-elements.
How often should NEN 2767 inspections be performed?
Typical inspection cycles are every 3 to 5 years for a full condition assessment. However, elements with a score of 4 or higher may warrant annual follow-up inspections to track deterioration before planned maintenance.
Can NEN 2767 be applied to infrastructure assets?
While NEN 2767 was originally designed for buildings, its methodology has been adapted for infrastructure assets such as bridges, tunnels, and quay walls. Several Dutch municipalities and Rijkswaterstaat use NEN 2767-based frameworks for civil infrastructure.
How does Geocadra support NEN 2767 inspections?
Geocadra provides structured digital forms with pre-configured NEN 2767 defect categories, drop-down severity/extent/intensity selectors, automatic condition score calculation, and photo-linked defect records with GPS coordinates — replacing paper-based inspection workflows entirely.
Is NEN 2767 certification required for inspectors?
There is no formal government-mandated certification. However, organizations like SSVV and BOEI offer recognized training programs and certification courses for NEN 2767 inspectors to ensure competency and consistent application of the standard.
