Paperless Office

I have spent the last 30 years working in a consulting engineers office. We have always used a lot of paper to prepare working drawings and project manuals for bid for construction of buildings. I do not believe the volume of paper for those purposes has changed.
Some portions of our work have paperless. I am able to access code books and design books online. My ASPE membership gives me access to the ASPE data books all of which are on line. These books cover the whole range of plumbing design. I have access to the current New York State codes for fire protection, for plumbing, for general building construction. They are all posted online for free. Thru my NFPA membership I have access to the NFPA family of codes which includes the national fuel code, national electric code, all of the fire codes. At work we have a paid subscription to the International Building codes online.  I also accumulate pdf files of miscellaneous codes.
I am able to research online for information.
Another paperless benefit is the electronic transfer of drawings and other documents between different offices and locations, allowing for bettr coordination of projects. A sidebar to this is teleconferencing and videoconferencing, allowing people from multiple locations to join in real time collaboration.
The advent of BIM programs like REVIT will require looking at a building model on a computer. Though for the time being, we will continue to generate contract documents for bid on paper.
