היקף העבודה כולל הריסה ואינסטלציה.

Literally, it means the scope of the work.

This is a very common Hebrew noun structure called a construct chain (סמיכות):

• היקף = scope / extent
• העבודה = the work

So instead of saying scope of the work, Hebrew simply puts the two nouns together: היקף העבודה.

No. In היקף, that ה is part of the word itself.

• היקף = scope
• ההיקף = the scope when the word stands alone

But in a construct chain like היקף העבודה, the first noun normally does not take the definite article. The whole phrase becomes definite because the second noun is definite: העבודה = the work.

So:

• היקף עבודה = scope of work / a work scope
• היקף העבודה = the scope of the work

It could, but היקף העבודה is more natural in formal or written Hebrew, especially in technical, legal, or construction language.

Compare:

• היקף העבודה = more compact, formal, standard in documents
• היקף של העבודה = possible, but less polished here

In English, of is required, but in Hebrew the construct chain often replaces it.

כולל is the masculine singular present-tense form of the verb לכלול, which means to include.

So:

• לכלול = to include
• כולל = includes / including with a masculine singular subject

Here the subject is היקף (scope), which is masculine singular, so כולל is the correct form:

• היקף העבודה כולל... = The scope of work includes...

Because Hebrew present-tense verbs agree with the subject in gender and number.

The subject here is היקף, which is masculine singular, so the verb is כולל.

If the subject were feminine singular, the verb would change:

• העבודה כוללת... = The work includes...

Other examples:

• הסעיפים כוללים... = The סעיפים include... (masculine plural)
• העבודות כוללות... = The works/jobs include... (feminine plural)

This is something English speakers often notice, because English verbs do much less agreement.

Because את is usually used before a definite direct object.

Here, הריסה and אינסטלציה are being listed as general categories of work, not as specific, already-identified items. So Hebrew does not use את.

That is why the sentence says:

• כולל הריסה ואינסטלציה

not:

• כולל את הריסה ואינסטלציה

If you wanted to refer to specific, definite items, you could say something like:

• כולל את ההריסה ואת האינסטלציה

Because they are being used as general categories: demolition and plumbing.

In this kind of technical sentence, Hebrew often lists work types without the definite article:

• הריסה = demolition
• אינסטלציה = plumbing

This sounds like a scope-of-work list. If you added ה, it would sound more like you mean specific demolition work and specific plumbing work already known from the context.

In this context, אינסטלציה usually means plumbing or plumbing work.

Although the word comes from a foreign source and may look like installation, in modern Hebrew construction language it usually refers to things like:

• pipes
• water systems
• drainage/sewage
• plumbing fixtures and related work

So in this sentence, אינסטלציה is best understood as plumbing, not general installation.

Yes. הריסה is a noun meaning demolition.

It comes from the verb להרוס, which means to demolish / destroy.

So:

• להרוס = to demolish
• הריסה = demolition

This is common in Hebrew: a sentence may use a noun for a type of work rather than a verb.

A natural pronunciation would be:

Hekef ha-avoda kolel harisa ve-instalatsya.

A few helpful points:

• היקף = hekef
• העבודה = ha-avoda
• כולל = kolel
• ואינסטלציה starts with ve-, so it sounds like ve-instalatsya

This sentence sounds fairly formal/technical, the kind of wording you might see in a contract, estimate, or work specification.
