269 East Grand takeoff

On Screen Takeoff was used to get the takeoffs for 269 East Grand.

Using the estimating template and usual a 'manual' back check, I was able to identify a few mistakes that were made using OST.  Some were simply human errors when copying and pasting - a few items were not copied.  There was also some rounding 'errors' where the template rounded up while OST was a bit more accurate.  Also where using the 'manual' method, general larger sizes were used to calculate footages, while again OST was a bit more accurate.
There was a bit of a learning curve in understanding what was taken off and how it was labeled and how it corresponded to the estimating template, for example, anchors should have been embeds. 

Despite these few differences, understanding how the takeoff was done and what numbers were used in the template, the data came to be quite close.  When rounding onto the template - the rounded number came out to be the same using either the OST number or the number from the template.  This was reassuring knowing that the data can be trusted a bit more.
