The question posted is unclear. If you mean what documents are typically produced as part of a project then these tend to vary from non saftey system to safety criticials system. They are also dependent on the disciplines, so for software deliverables the assurance would vary to that of a Civils construction.
Below is list of documentation that you could be expected to deliver and again is dependent on the scopes of works along with the company assurance process etc:
