Official websites use .gov
A .gov website belongs to an official government organization in the United States.
Secure .gov websites use HTTPS
A lock (

Unfortunately, there is not a way to merge files. The web tool is definitely the way to go when you have multiple contractors involved as you can create a generic log in and each contractor can work on the same project file to enter their information (e.g., building envelope, lighting, mechanical).
Project sharing will soon be more user friendly.
