There is no one set of guidelines, there are many writings on the subject but context is very important as to whether or not they apply to a specific project.
Lifecycle model, technical maturity, process maturity, domain, risk level, whether you are considering just labor and/or material costs, and many other factors can have a very big influence.
Your best bet is trying to find similar projects with sufficient historical data to use analogous or parametric estimating. Saving Changes...

I've used 15-17% for project management, in the past. Of course, this was predicated on a specific industry and a specific type of solution, as Keith explained. Saving Changes...

It will depend on the type of project and maturity of the company you are in.
If there is a similar project where you can check the lessons learned and estimations would be a great approach. However, if it is the first time you are planning this type of project, don't do it alone, talk to the leads, identify milestones, clarify the scope as much as you can, identify the assumptions, exclusions and risks and give your best guess!!

Some architect associations have costing guidelines for infrastructure projects. The Royal Architectural Institute of Canada has "A guide to Determining Appropriate Fees" The copy I have is dated 2009. On any given project the architect contract may include PM services.

"Impartial observers from other planets would consider ours an utterly bizarre enclave if it were populated by birds, defined as flying animals, that nevertheless rarely or never actually flew. They would also be perplexed if they encountered in our seas, lakes, rivers and ponds, creatures defined as swimmers that never did any swimming. But they would be even more surprised to encounter a species defined as a thinking animal if, in fact, the creature very rarely indulged in actual thinking."
