Объём работ требует согласования проекта.

Because the subject of the sentence is объём (volume / amount / scope), and объём is singular.

• Объём = singular noun
• работ = of work / of tasks, dependent on объём

So grammatically this works like English The amount of work requires..., where amount is the subject, not work.

After nouns like объём (volume, amount, scope), Russian normally uses the genitive to show what the volume/amount is of.

So:

• объём чего? → работ
• literally: volume of works/tasks

Why plural?

Because in this kind of technical or administrative phrase, работы often means tasks / pieces of work / works, so объём работ means the amount/scope of work.

This is a very common pattern:

• объём работ = scope of work
• объём информации = amount of information
• объём продаж = sales volume

It is a set phrase often used in business, engineering, construction, and project language. It usually means:

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

In many contexts, scope of work is the most natural English rendering, especially if the sentence is about project procedures, approvals, or planning.

The verb требовать commonly governs the genitive of the thing being demanded, required, or needed.

So:

• требовать чего? → согласования
• требует согласования = requires approval/coordination

This is normal Russian usage, especially in formal or written style.

Examples:

• требовать помощи = to require help
• требовать объяснений = to demand explanations
• требовать ремонта = to require repair

So требует согласования is grammatically expected.

Because требует takes the genitive, and the genitive singular of согласование is согласования.

Compare:

• nominative: согласование
• genitive: согласования

So:

• это согласование = this is an approval/coordination
• требует согласования = requires approval/coordination

Because проекта depends on согласования.

The phrase согласование проекта means:

• approval of the project
• coordination of the project

So inside the bigger sentence, you have two layers:

1. требует согласования
   requires approval
   → согласования is genitive because of требует

2. согласование проекта
   approval of the project
   → проекта is genitive because it depends on the verbal noun согласование

So yes, there are two genitives here, but for different reasons.

Roughly yes, but the structure is more noun-based and more formal.

• согласовать проект = to approve / coordinate the project
• согласование проекта = approval / coordination of the project

Russian official and technical style often prefers this kind of noun phrase over a verb phrase.

So instead of saying something more verbal like:

• Нужно согласовать проект = The project needs to be approved

the sentence says:

• ...требует согласования проекта = ...requires approval of the project

This sounds formal, administrative, and impersonal.

Because this sentence is written in a formal, bureaucratic style, where Russian often prefers abstract nouns.

So:

• требует согласования проекта = formal, official style
• нужно согласовать проект = more direct and conversational

Russian administrative writing often sounds more nominal than English. English also does this sometimes:

• requires project approval
  instead of
• requires that the project be approved

So the Russian sentence is perfectly natural for formal written language.

It depends on context.

In technical, administrative, and project contexts, согласование often means:

• approval
• clearance
• sign-off
• sometimes coordination

It is usually not the same as simple personal agreement in conversation.

For example:

• согласие = agreement/consent in a general sense
• согласование = a process of official approval, review, coordination, or sign-off

So in a project sentence like this, approval of the project is often the most natural English choice.

Yes. Russian word order is flexible, because case endings show the grammatical relationships.

The neutral order here is:

• Объём работ требует согласования проекта.

But you could also say:

• Согласования проекта требует объём работ.

That version puts more emphasis on what is required.

Even though word order can change, the cases still tell you:

• объём = subject
• работ = dependent on объём
• согласования = object required by требует
• проекта = dependent on согласования

So the meaning stays basically the same, but the focus changes.

A very literal breakdown is:

• Объём = volume / amount / scope
• работ = of work / of tasks
• требует = requires
• согласования = approval / coordination
• проекта = of the project

So literally:

The volume of work requires approval of the project.

A more natural English version might be:

• The scope of work requires project approval.
• The amount of work requires approval of the project.

The best choice depends on the context.

Because Russian has no articles.

Russian does not have direct equivalents of English a/an and the, so definiteness is understood from context.

So this sentence could mean, depending on the situation:

• The scope of work requires approval of the project
• A scope of work requires project approval
• The amount of work requires the project’s approval process

In real use, context tells the listener which is intended.

Объём is pronounced approximately ab-YOM.

Important points:

• ё is pronounced like yo
• ё is always stressed
• the stress is on the second syllable: объём

In printed Russian, ё is often written as е, so you may sometimes see объем, but it is still pronounced объём.

That is useful to remember, because stress matters a lot in Russian.
