A great substitute to a roll of drawings would be to store hundreds of PDFs to be read with a PDF reader and annotator like Goodreader. Especially for onsite reference, it is important to be able to pull out information on the fly. In the case of a large building, the zooming function preserves the text and line clarity in vector format. Though there is a load time of about 5 seconds, it is indispensable when you have to climb scaffoldings and hop around site materials without having to carry huge scale documentation in hardcopy.

Aside from drawings, I store building codes from the various departments for reference, especially when in doubt or being challenged, which happens ever so often during discrepancies or discussions with other consultants or site contractors.
