After a contractor has signed up with my Design/Build Project, they are able to use the site as an interactive database for each of their client's projects. Each project has folders for information ranging from sales contracts to construction documentation. The contractor can give each member of the project team (home owner, lead carpenter, estimator, administration etc.) access to the system on the site and that information which pertains to each member.  For example the home owner can have access to drawings, contracts and product selection information, but not have access to internal company data such as internal procedures and financial information.
