Техническое задание включает объём работ.

Because задание is a neuter noun, and the adjective must agree with it in gender, number, and case.

• технический = masculine
• техническая = feminine
• техническое = neuter

So:

• техническое задание = technical assignment / technical specification

Here both words are in the nominative singular.

It is in the nominative case, because it is the subject of the sentence.

The sentence structure is:

• Техническое задание = the subject
• включает = includes
• объём работ = the object

So literally:

• The technical specification includes the scope of work.

Включает is the 3rd person singular present tense form of включать.

The verb changes to match the subject:

• я включаю = I include
• ты включаешь = you include
• он / она / оно включает = he / she / it includes
• они включают = they include

Since техническое задание is singular, the verb is also singular:

• Техническое задание включает ...

The verb включать is imperfective. In the present tense, it often describes:

• a general fact
• a regular property
• what something contains as a rule

That fits this sentence well: it states what a technical specification includes.

The perfective partner is включить. A present-tense-looking form from a perfective verb usually has future meaning:

• включит = will include

So:

• Техническое задание включает объём работ = The technical specification includes the scope of work.
• Техническое задание включит объём работ = The technical specification will include the scope of work.

The whole phrase functions as the direct object, so объём is in the accusative case.

However, for an inanimate masculine noun, the accusative singular looks the same as the nominative singular:

• nominative: объём
• accusative: объём

So although the form does not change, its role in the sentence is accusative.

Because работ is the genitive plural of работа.

This is a very common Russian pattern: a noun meaning volume, amount, scope, quantity, part, list, etc. is often followed by another noun in the genitive.

So:

• объём работ = volume/scope of work
• literally: the volume of works/tasks

Compare:

• список документов = list of documents
• объём информации = amount of information
• план работ = work plan / plan of works

Because Russian often uses the plural in expressions like scope of work, where English may use singular work as an uncountable noun.

In Russian, работы / работ often refers to:

• tasks
• jobs
• kinds of work
• work items

So объём работ is a standard phrase meaning something like:

• scope of work
• amount of work to be done
• volume of tasks

Yes, it is a very common set phrase, especially in technical, business, legal, and project contexts.

It usually means:

• scope of work
• volume of work
• amount of work involved

In practical translation, scope of work is often the most natural English equivalent.

Literally, yes:

• техническое = technical
• задание = assignment / task / specification

But in real usage, техническое задание is often translated more naturally as:

• technical specification
• statement of work
• project brief
• requirements document

The best translation depends on context. In engineering, IT, design, and procurement, technical specification is often a very good choice.

Because Russian has no articles.

Russian does not use words like a or the. Whether something is definite or indefinite is understood from:

• context
• word order
• stress
• the situation

So Техническое задание включает объём работ can mean:

• The technical specification includes the scope of work
• or, in another context, A technical specification includes a scope of work

English needs articles; Russian does not.

Yes, Russian word order is more flexible than English word order. But changing the order can change the focus or sound more/less natural.

The neutral order here is:

• Техническое задание включает объём работ.

You could also say:

• Объём работ включает техническое задание.

But that means something different: The scope of work includes the technical specification, which is probably not what you want.

A more natural variant with similar meaning is:

• В техническое задание входит объём работ.
• literally: The scope of work enters into the technical specification
• natural English: The scope of work is included in the technical specification

So yes, order matters for meaning, even though Russian is flexible.

No. A very common alternative is входит в or входит.

Compare:

• Техническое задание включает объём работ. = The technical specification includes the scope of work.

• В техническое задание входит объём работ. = The scope of work is included in the technical specification.

Both are correct, but the structure changes:

• включать takes a direct object
• входить в takes в + accusative

So:

• включает объём работ
• входит в техническое задание

Yes. In Russian, ё is often written as е in ordinary texts, so you may see:

• объём
• объем

Both refer to the same word.

But the pronunciation is with yo:

• объём = approximately ab-YOM

For learners, it is very helpful to remember the ё, because it shows both the pronunciation and the stress.

A learner-friendly pronunciation guide:

• Техническое задание включает объём работ.
• tyekh-NEE-chees-kaye za-DAH-nee-ye vklu-CHA-yet ab-YOM ra-BOT

Approximate stress:

• техни́ческое
• зада́ние
• включа́ет
• объём
• рабо́т

The most important thing is to keep the stress in the right place, especially in:

• зада́ние
• включа́ет
• объём
• рабо́т
