Looking for information on Survey in the Help Files, I found references to linked native preference files. These only applied to Ss3 and Ss4 and really need to be purged and replaced with more current information.
What specific information related to Survey are you looking for? I can submit an enhancement request for development to include information in the help file.
For more information about the Road and Site design tools, visit the Road and Site design WIKI at: http://communities.bentley.com/products/road___site_design/w/road_and_site_design__wiki
I am not sure, but I do recall seeing this deficiency and wanted to make sure it was addressed. I may have gone into the product and found what I was searching for. It's possible I was looking for explanations of the link and control codes, in the help, as opposed to in the Wiki.
