A little.
I've read up on facilities and it highly depends which kind of objects should be contained as facility reach from mostly safe-class up until specializing in partially uncontainable SCPs.
In general what I would be shooting for would be an armed research facility, hosting SCPs requiring containment (not only objects).
if we want to go for Keter SCPs mostly, it would need to be an area, of the world, nuclear fail-safes and such. Area-02 from canon would be one in that direction.
For a facility dealing with mostly anything, albeit Keter there are just not containable but "harmless" I would actually suggest Site 11:
Site-11 Site-11 is a large-scale Foundation facility located in the mid-western United States consisting of an entire self-sustaining community including residential housing, commercial businesses, and industrial/manufacturing facilities as well as an extensive underground containment and research complex. The Foundation maintains strict tracking of all personnel and civilians within Site-11 and as such, the facility is often used as a safe location for personnel requiring additional security and protection. Objects contained at this facility include: SCP-986 scp-wiki.net/secure-facilities-locations(some SCPs there include: 2566, 3852, 2811, exit point for 1021, 068, book about/frm 3547, appearance of 2536, 4332 (that must have been a funny incident!), 2923, 3131, 3453, 4388, 1444, 270. 4701, 3255-2,
Site furthermore contains biological, secure and maximum security storage, anomalous computing center as well as holding and humanoid containment, from only what I've seen and read so far. it is a large hub for the location in the US, containing apparently few task forces (Witchhunters, Bibliographers and Shamanic Analysis Unit e.g.) and sending out or storing things.
For me it sounds like a good start, especially if we are running research and containment at the same time as people can just meet up outside work.
For the Mobile Tasks Forces, which we would most likely need, one could orient itself with the rather well described Task Forces of the foundation
scp-wiki.net/task-forces or just crate something fitting the idea of the roleplay.
For recovering a set of MTF operatives and containment teams is usefull, as well as some researchers. Containment teams form canon are MTF-Beta-7, MTF-Omega-7 (Pandora's Box) which is not suited to be any more than appearing, Edna-84) - so I guess there is room to freely create.
For the running of the show researches, security personnel and such are also required.
For any purpose where a new object should be introduced and because I guess it is needed knowledge I would refer any participant to
object classes as well as
Security and clearance. The about page offers a nice introduction:
scp-wiki.net/about-the-scp-foundationIn general apart from a few things in security and object classes, as well as a little organization SCP is very flexible.
