surveying work

I have a work in surveying subject ,I already did it ,but I got some comments in it as you can see that in the very end if the page .also  you will see my friends work which is in the same subject , it is just for helping you to get the idea . Also you will find the assignment paper here .

I want you to look at all the papers , then look to my old work with the comments,  Comparing those to my friend work ,and rewrite it again .
