What exactly are the differences between using について and につき? In the following
sentences, my grammar book says they are not interchangeable, but I don´t
quite understand why. Thank you very much for your help.

> この記事に **ついて** のご意見をお聞かせください。
>
> 新しい事業計画 **につき** 、これから御説明いたします。

Difference between について and につき
> この記事 **についての** ご意見をお聞かせください。  
>  Please tell me your opinion **about** this article.
>
> 新しい事業計画 **につき** 、これから御説明いたします。  
>  Now I'd like to talk **about** the new project plan.

Not interchangeable in the first sentence due to the の after について.

But this would be fine:

> 新しい事業計画 **について** 、これから御説明いたします。  
>  Now I'd like to talk **about** the new project plan.

  * Also, 「につき」has an additional common usage  
which isn't interchangeable with「について」:

Here it is the same as saying, 「工事中 **なので** 」or「工事中 **のため** 」

" **Due to** Construction" / " **Because of** Construction"  
"Please Refrain from Parking"
