\subsection{Elements of Costing}  A detailed costing of the TLEP project does not exist yet, and one of the aims of the starting TLEP design study is to produce it. Very preliminary and indicative Indicative, very preliminary,  estimates are summarized given  in Table~\ref{tab:cost}. Not surprisingly, the main cost drivers for the whole complex are the tunnel, the shafts and the related services and infrastructure (including access roads). The next two cost drivers are the 12 GV RF system and the 80 km of magnets. The TLEP project, however, may be considered as a precursor to the VHE-LHC, in which case the tunnel, the tunnel services and the magnets (which could be used for the VHE-LHC injector) could be shared between TLEP and the VHE-LHC. In view of the large number of Higgs bosons expected to be produced at TLEP (Section~\ref{sec:Higgs}), the cost of each Higgs boson is expected to be exceedingly competitive, be it expressed either in CHF per Higgs boson or in MW per Higgs boson~\cite{1308.2629}. \begin{table}  \begin{center}
