Meat a girl from job, but I want to be a friends. How would you ask for hangout?

Everytime I want to ask her out she’s with her old friends and I don’t want to look like I’m inviting her on a date. She’s kind and genuinely good person. We actually hang out one time, but as said… I don’t want to look like I’m interested in any other way than being friends.

Any advices, guys?

P.S.: They (her company) are moving to another location in a month. So things are tight… (atleast i think)
