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