When did Chadwick get moved to 1812 and where is 1812 again?

When Hardesty got ARM Chadwick moved from 10 to 12 (Westminster)

What about:

Mark Hudson (please tell me he got out of 1802) - Department head of RCC
Matt Treese (I know he left but where to?) - PHARM Sales
Rub Mcgroin (Barney Rubble) - Group Rental Manager of Truck Rental
