Experiments at the LHC will allow for the exploration of an energy range which has never been reached in collider physics up to now. However, extracting signals of new phenomena and discriminating between different models is only possible if the predictions of the Standard Model and of prominent extensions are known precisely enough. To this aim higher orders in perturbation theory have to be calculated, in particular one-loop amplitudes for multi-particle production. This should be done in a largely automated way, to provide tools similar to the leading order tools we have at hand today. The talk will give an overview of what has been achieved in this field recently and present a general framework for automated next-to-leading order calculations. Examples including direct photon production and ZZ+jet production at NLO will be discussed.
