Bærekonstruksjonen kontrolleres.

It is a compound noun:

• bære = to carry, bear, support
• konstruksjon = construction, structure
• -en = the definite ending

So bærekonstruksjonen means the load-bearing structure or the supporting structure.

Norwegian often combines words into one long noun where English would use several words.

Because Norwegian usually adds the definite article to the end of the noun.

So:

• en konstruksjon = a structure
• konstruksjonen = the structure

The same thing happens here with bærekonstruksjonen = the supporting structure.

It is singular.

The ending -en here shows a definite singular form for an en-word in Bokmål.

If it were plural, you would get something like:

• bærekonstruksjonene = the supporting structures

So Bærekonstruksjonen kontrolleres refers to one structure.

The -s ending marks the passive voice.

So:

• kontrollerer = checks / inspects
• kontrolleres = is checked / is inspected

That means the sentence focuses on what happens to the structure, not on who does the checking.

Not always. This is an important vocabulary point.

Although kontrollere can sometimes look like English control, in many technical or practical contexts it means:

• check
• inspect
• verify

So Bærekonstruksjonen kontrolleres will often be better translated as The supporting structure is being checked or The supporting structure is inspected / checked, not necessarily is controlled.

Yes. That is another common way to make the passive.

Both can mean roughly the same thing:

• Bærekonstruksjonen kontrolleres
• Bærekonstruksjonen blir kontrollert

A useful difference is this:

• -s passive often sounds a bit more formal, written, technical, or general
• blir + past participle is often more common in everyday speech when talking about an ongoing event

So in a technical report, kontrolleres sounds very natural.

An active version would name the person or thing doing the action, for example:

• Ingeniøren kontrollerer bærekonstruksjonen. = The engineer checks the supporting structure.
• Man kontrollerer bærekonstruksjonen. = They/one check(s) the supporting structure.

In the passive sentence, that agent is left out.

It is present tense passive.

Depending on context, it can mean things like:

• is checked
• is being checked
• gets checked

Norwegian present tense is often broader than English present tense, so the exact English wording depends on the situation.

This is normal Norwegian main-clause word order: V2 word order.

The sentence starts with the subject:

• Bærekonstruksjonen = subject

Then comes the verb:

• kontrolleres = verb

So the pattern is:

• Subject + Verb

If another element came first, the verb would still normally stay in second position. For example:

• I dag kontrolleres bærekonstruksjonen. = Today, the supporting structure is checked.

Here I dag comes first, but the verb kontrolleres still stays in the second position.

A rough learner-friendly guide is:

• bære: the æ is somewhat like the vowel in British English air, but shorter and cleaner
• konstruksjonen: roughly kon-struk-sho-nen

Very roughly, the whole word can be approximated as:

• BAIR-eh-kon-struk-SHO-nen

That is only an approximation. The exact Norwegian sounds are different from English, especially æ and the rhythm of the word.

Yes, especially in technical, formal, or report-like language.

It sounds like the kind of sentence you might see in:

• an inspection report
• construction documentation
• engineering instructions
• safety procedures

In everyday conversation, a speaker might be more likely to say something longer, such as:

• Vi kontrollerer bærekonstruksjonen.
• Bærekonstruksjonen blir kontrollert nå.

But the original sentence is perfectly natural in the right context.
