PDF mark ups need adding to DWG file

I have a PDF document that contains mark ups that I need adding to an existing AutoCAD DWG file (X2-G-MH).

There are 4 pdf pages in total that have been clearly marked up that I need someone to add to the dwg.

This work needs to be very accurate and to scale. I have also attached another CAD file (X1-G-MH) that shows a similar job. As you can see, it shows the existing detail in red and also some new detail that has recently been added. This should give you a good idea of the standard to follow & layers etc.

This is easy work but needs a high attention to detail. If you are interested in this job, I ask you please to add a section of the mark up detail from the attached pdf to drawing (X2-G-MH) so I can see the expected results. I will issue the rest of the marked up pdf's to the successfully freelancer.

(Please note: All pipes and ducting need to be displayed as full, true diameter size. The single pipe lines shown within the mark ups are showing the route only).

This work needs to be completed by Monday 22nd July.

Any questions, please don't hesitate to ask.

Thanks
