You will find that there is a large variety in the bid detail that you receive. Depending on the work that you want done, some contractors are reluctant to itemize because then you will see where they make their profit.
For example, we had a re-model for an investment property. We told our manager that we wanted to compare apples to apples bids, so he recommended that the contractors be directed how to submit the bids. In our case the format was to provide the cost of each item, then include their profit as a line item. It made it a lot easier to compare and negotiate.
The other factor to bear in mind is that some contractors work more "by the seat of their pants" and simply do not have the type of data that you are requesting. For them to provide a bid in that format "would take too much time".
