[Grammar] Please help to confirm whether it is correct

[sunnyaykl]

I invited a contractor to quotes for a construction works last week. The contractor has replied to me, but the number of plant is changed, so i want to resent a updated schedule to him for the new quotation.

Can i say:
Thank you for your quotation on xx 2020, due to the number of plant is changed, please find the updated schedule for your quotation.

Is there any faults of grammar?
Sorry, i know my English is not good enough.
Thank you for your help.

Note my corrections above. I don't know what you mean by "the number of the plant" or "an updated schedule".

Thank you so much.

'The number of plant' means the number of machine which is used for construction.

'The updated schedule' means the updated lists which show the machine's name or type.

"The plant number has changed."
"Attached is a revised schedule of works showing the amended plant number."

 

[sunnyaykl]

"The plant number has changed."
"Attached is a revised schedule of works showing the amended plant number."

Can I say the following?

And may I know the reason for changing 'is changed' to 'has changed'?
I think it is a passive voice.
Thank you.

Thank you.

The present perfect tense is appropriate for an action that happened in the past which is relevant to the present.
"Is changed" is in the simple present tense.

Plant number is ambiguous - does it mean the registration number of a plant or the total number/units of plants? I think it is the latter as it affects the pricing.

Yes, it means the total units of plants. If I use "the quantity of plants", will it be better?

The number of plants would be simpler.

The number of plants would be simpler.

And if you mean machines, say machines. Plant has several meanings, but none of them is machine.

I thought you were hiring someone to landscape your yard.

And if you mean machines, say machines. Plant has several meanings, but none of them is machine.

A plant is the machinery used in an industrial process, e.g. the plant set up on site in a construction project for the production of concrete or the fabrication of steel bars.

When it refers to an industrial place (e.g. a manufacturing site), it can be countable, but when it refers to machinery, it is usually used as a mass noun. See entries #2 and #2.1 for "plant" as a noun in the following link.

sunnyaykl: are you referring to the quantity of machines involved or to the number (code) of one particular machine?

I mean the quantity of machines.

Why did you say plant when you mean machines? A plant is a setup of machines. I suppose different types of machines are involved.

I agree. (See post #10.)

It might be an industry term, but I've never heard it.
