I don't mean to give you a smart ass answer but there is no such thing as "quickly build relationships". Relationships take time to build and cannot be done too quickly. However, you can start off with a good impression by being open, honest and most importantly a good listener to your co-workers. Show genuine interest in them but don't over do it. Talk to them about non-work related stuff if they seem interested. Respect their space/privacy but go hang out with them once in a while. Appreciate their work no matter how mimimal it may be. Rinse.Repeat.
