I think your question is actually:
"Where can I find standard procedures and policies for operating a network with mulitple system administrators?" I doubt anyone has a ready made template, since no two networks have the exact same resources, performance requirements, needs, user base, and security policy. But, in order to help you out, it might help if you posted a little about your own experience level, so you don't get too many answers that are not at the appropriate level. I would recommend checking out the SAGE resources at the USENIX web site. Lots of information there on system administration and some good recommended books that will probably tell you exactly what you are looking for. From experience, I can tell you that you probably need to first determine the requirements for your network, then determine the manner you are going to distribute your system administration tasks (including determining the distribution of authority on the system). Probably all the administrators don't need the same level of privelege, so alternate tools to manage those priveleges need to be considered. Here is the link to the SAGE page, take a look at the resources there, see if this is what you are looking for, in a general sense atleast....
