Structural Estimation for 5 Sunset Lane

I want you to verify to take offs that I had another estimator create, your job is to just check this work below against the attached drawings.

In other words, you are just checking the below information by reviewing the drawing set to verify the accuracy. If you find any errors you just need to highlight the error and put what the correct answer is. The final result will be that all of the lines that are referenced here contain accurate information whether it is a quantity, takeoff, or count. If there is any large item that is missing that you feel needs to be added please add it and indicate in the document that you have done so.

Here is where the document for review begins:
