Full Scale Systematic Steps for EPCM

In this study DAMA Engineering has intended to give a case study that explains all main stages (all scales of work) in the projects DAMA has been carrying out. Case study is explaining three different level engineering studies (scoping, feasibility, bankable- feasibility) from resource estimation level to end of the plant design and EPCM period of the investment. The main conclusion is to show necessity of following systematic steps (scoping, feasibility, bankable- feasibility) to make sure that the estimated CAPEX (initial/future) and OPEX are representative with the given contingency for each level (scoping±35-45%, feasibility ±15-25%, bankable-feasibility ±10-15%) studies up until investment period (EPCM). This case study showed that estimated project costs are well inside the range of real investment.
