Could you list advantages and disadvantages between EPC and EPCM ?

EPCM model the contractor does no building or construction; rather they develop the design and manage the construction process on the owner's behalf FOR EXAMPLE:FLOUR,PETROFAC,FOSTERWHEELER

EPC (Engineering, Procurement and Construction): means the company is contracted to provide engineering, procurement and construction services by the owner FOR EXAMPLE:DAELIM,TR,SK,JGC

The key difference is that under an EPCM contract, other parties construct the project – the EPCM contractor is not the builder/constructor.

EPC is much higher Risk than EPCM.

EPCM is limited to construction management and most of the time linked to Mna/Hr rate were EPC is lump sum.
