In my experience Pre-Construction Information (PCI) can be both Works Information (often constraints) and Site Information (descriptions of the Site and details of surveys etc). It seems to be because it's drafted by people who's focus is health and safety and not contracts. My solution is to include in both the Site Information and the Works Information a table that makes clear what the status is of each section / clause of the PCI.
You are right that the PCI is a CDM requirement, however you risk omissions, ambiguities and inconsistencies in or between the documents forming the contract if you include the PCI in the contract without categorising it as I've suggested. NEC3 ECC clauses 17.1, 60.3 and 63.8 are all relevant to this situation, which if it arises will rarely (if ever) go in the Employer's favour.
