I hate to give a bad introduction but as you're obviously not here to talk to people on the forums I'm going to get straight to the point.
I'm giving you a warning for posting at random with an obvious intent to get building access. Do not do this again.
Go to http://www.technicpack.net/tekkit/ and download the tekkit client, log into minecraft with the technic launcher (selecting tekkit from the drop down) .. Put in the server IP and you're good to go!
