Die boubeheerbeampte gaan die afmeting en die grondgebruik na.

No. Here gaan ... na is the separable verb nagaan, which means to check, to inspect, or to review.

So in this sentence, gaan is not a future marker. It is the conjugated part of nagaan.

Compare these two patterns:

• Die boubeheerbeampte gaan die afmeting en die grondgebruik na.
  = The building control officer checks/reviews the measurement and the land use.

• Die boubeheerbeampte gaan die afmeting en die grondgebruik nagaan.
  = The building control officer is going to check/review the measurement and the land use.

That difference is very important in Afrikaans.

Because nagaan is a separable verb.

In a normal main clause, the conjugated part goes to the usual verb position near the beginning of the sentence, and the other part moves to the end:

• nagaan → gaan ... na

So:

• Die boubeheerbeampte gaan ... na.

This is a very common Afrikaans pattern with separable verbs.

Boubeheerbeampte is a compound noun. Afrikaans often joins several words into one long noun.

You can break it down like this:

• bou = building / construction
• beheer = control / management
• beampte = official / officer

So boubeheerbeampte means something like building control officer or building control official.

A good strategy with long Afrikaans words is to split them into smaller familiar parts.

Because Afrikaans, like Dutch and German, very often writes compound nouns as a single word.

English often writes similar expressions as two or more words, such as:

• building control officer
• land use
• city council meeting

Afrikaans tends to combine these into one word when they form a single noun idea. So boubeheerbeampte is completely normal.

Because both nouns are definite: the measurement and the land use.

Afrikaans uses die as the definite article for:

• singular nouns
• plural nouns
• all genders

So unlike languages that change the depending on gender or case, Afrikaans keeps it simple: die.

It is repeated here because there are two separate definite nouns joined by en:

• die afmeting
• die grondgebruik

Afmeting usually means measurement or dimension.

Depending on context, it could refer to:

• a measurement that has been taken
• the dimensions of something
• an official measured value

In English, dimensions is often plural, but Afrikaans may use the singular afmeting if the context treats it as one measured item or one measurement issue.

Literally, it is:

• grond = ground / land
• gebruik = use

So grondgebruik means land use.

This is the kind of term you often see in planning, zoning, property, or municipal contexts. It refers to how land is used, for example residential, agricultural, commercial, and so on.

Yes. The structure is normal for a main clause with a separable verb:

• Die boubeheerbeampte = subject
• gaan = finite verb
• die afmeting en die grondgebruik = object
• na = separated particle

So the pattern is basically:

Subject + finite verb + object + particle

If the verb appears in a subordinate clause, the two parts usually come back together:

• Ek weet dat die boubeheerbeampte die afmeting en die grondgebruik nagaan.

That is a very useful contrast to learn:

• main clause: gaan ... na
• subordinate clause / infinitive: nagaan
