NEN 2767 methodology: step-by-step from assignment to report

A condition assessment under NEN 2767 runs from the first assignment to a multi-year plan. The method is described in the standard, see NEN . You go through six steps, and each step produces something you use in the next one.

The steps follow a fixed order. If you skip the scope, you get a report later that does not fit the question. If you do not request the file, the inspector has to search on site for information that already exists. The overview of the standard is on NEN 2767 condition assessment.

Fictional example: VvE Parkzicht wants to know which components need replacing within five years. That question is where the whole process starts.

Overview of the six steps

Step	What the client provides	What comes out
1. Assignment and scope	The purpose, the list of objects and the desired outcome	An assignment letter with scope and schedule
2. File review	Building drawings, earlier reports and the maintenance history	An inventory of the building parts
3. Recording elements and defects	Access to the building and the technical rooms	A list of defects with photos and locations
4. Scoring	No extra data needed	A condition score per building part
5. Reporting	Additions from the board or the manager	A report with scores, defects and priorities
6. Translation into an MJOP	The desired period of the plan	An MJOP with costs per year

Determine the assignment and scope

Start with the question: what will you use the outcome for? For an MJOP, you usually measure the whole building. For a single problem, a limited scope is enough. Record the objects, the building parts and the period in an assignment letter.

VvE Parkzicht chooses the whole building, because the board wants an MJOP for the coming five years. The assignment letter lists the façade, the roof, the lift installation and the shared spaces.

Carry out the file review

Before the inspector comes on site, they collect the data that already exists. Think of building drawings, earlier maintenance reports and an overview of what has been replaced in recent years. That data helps to define the building parts clearly.

The result is an inventory of the building parts. You use that inventory later to assign defects to the correct components. You can read how to divide the building on decomposition.

Record elements and defects

On site, the inspector goes through the building parts and records every defect. They note the location, the extent and the stage of the defect, and take photos. An inspector records defects objectively.

The defect is the basis of the score. At VvE Parkzicht, the inspector found cracks in the façade joints, on several floors. How a defect is assessed is set out on defects. The visit itself is described on inspection on site.

Apply the scoring

For each building part, the inspector determines a condition score. The score follows from the severity of the defect, the extent and the stage. The scale runs from 1 to 6. A 1 means as-new condition, and a 6 means replacement is needed.

At VvE Parkzicht, the façade received a 4 and the roof a 5. You can read exactly what each score means on condition scores 1 to 6.

Report

The report contains the scores per building part, the defects with photos and a list of priorities. The board or the manager reads in it what must happen now and what can wait. Check whether the report follows the scope from step 1.

A good report is also easy to read for a non-specialist. Ask the inspector for an explanation of the main findings if these are not in the report.

Translate into an MJOP

As the last step, the inspector attaches a cost amount to each measure. This is often based on cost benchmarks. The result is a multi-year plan with the costs per year. You can read what that plan looks like on MJOP based on NEN 2767.

The cost of the repairs is not the same as the cost of the assessment. The repairs come on top of that, and the inspector cannot carry them out for you.

Frequently asked questions

What do I have to provide myself?

Provide the building drawings, earlier reports and the maintenance history. Also give the inspector access to the building and the technical rooms. How long it takes to find that data depends on how your administration is organised.

Can I carry out the steps myself?

You can form a first picture of the condition of the building yourself. That is not yet a condition assessment under the standard. The defects are recorded by an inspector who has mastered the method. See inspector and training.

What is the difference between scoring and reporting?

In scoring, the inspector determines a number per building part. In reporting, they turn that number into a document you can read and use. The report also contains the defects and the priorities.
