What are the drawings presented for a post-tensioned slab ?
(OP)
Hi, I have a post-tension slab I want to draw it in autocad but i don't know how many plans to present and how each plan layout, can anyone present any sample autocad or pdf showing layout of slabs presented by a company or office ?

Practices vary around the world. In the North America (and the US specifically) the EoR produces a PT design drawing that shows high and low points, forces, and a general layout, then the PT supplier will produce PT shop drawings that meet that design. In other parts of the world the consulting engineer will detail the PT fully - number and spacing of tendons, rebar T and B, sometimes formwork profiles too.
Where are you practicing and what do your colleagues do?

The structural engineer will first produce design drawings that show the general PT arrangement, high/low profile points, forces etc., and top and bottom rebar etc. The PT supplier/installer will produce the shop drawings based upon the engineers design drawings and project specifications.

Any chance you can repost the drawings in a scaleable format. When I zoom in to see the notes, the 'jaggies' totally obscure the text.

Will do. But I have to first modify the PDF files to delete the title blocks etc - project the 'guilty'.
FYI - I was was NOT the EoR on this project - we just did the PT repairs consisting of de-stressing, de-greasing, re-greasing and re-stressing of several hundred tendons to a 6 year old structure. Long story.

FYI - standard US PT detailing/symbols used, so legend for tendon symbols is:
