We use e-Builder to track, document, and reply to various construction correspondence related to projects in construction. This includes RFIs, submittals, and sketches. The system is easy to use, though sometimes I am not always certain what fields to fill out. This likely is due to not having an educating session to go over the system's features specific to my role in the project. I do like being able to click the link in the emails sent to take me directly to the appropriate action items.
