Narrative:

I was pilot flying on a visual approach to 28C. At about 1000 ft AGL; I noticed that the captain (pilot-monitoring); realized that he had not called the tower controller to obtain landing clearance. The frequency was congested and he was not able to contact tower successfully. At about 100 ft AGL; the captain instructed me to go-around; which I then did. After following ATC go-around instructions; we received a TCAS RA to climb; which I did. We were then eventually cleared for another visual approach to the same runway; and landed uneventfully; this time receiving landing clearance. As pilot monitoring; I should have verified and cross checked that we had received landing clearance earlier in the approach. I now will verify that landing clearance has been received; immediately after the 'before landing checklist' is performed.

Title: When the E-145 flight crew on final approach to ORD realized they hadn't received a landing clearance and were unable to break into the busy tower frequency they initiated a go-around during which they received and responded to a TCAS RA.
