The information is accurate! It helps me a lot with my cost estimating!

We love your book in our department! It helps us prepare many engineering estimates which would not be possible if your book was not around.

At first, I was confused about how to use the online interface and find things but I clicked on the live support and the person was kind, and patient, and showed me where to find things quickly. He also taught me how to use the search terms better. I highly recommend this product!

Very happy with E-book.
