The search for the Higgs boson and for physics beyond the Standard Model arethe major motivations behind the LHC experiment. In many scenarios the successof the experiment depends on the knowledge of signal and background event ratesat least at one-loop precision. We present the approach of the \texttt{GOLEM}collaboration to build a highly automated framework for the calculation ofmatrix elements at the one-loop level, which is based on the evaluation ofFeynman diagrams. Part of this effort is an open-source library for thenumerical evaluation of tensor integrals. As an application, some results forthe process $pp\to b\bar{b}b\bar{b}$ calculated with this method are presented.
