Weight Value – Mixture of M-H and Cost

13 Oct Weight Value – Mixture of M-H and Cost

Reference to our post about Weight value and Earned value, there were comments as regards using the mixture of M-H and cost for Engineering, Procurement and Construction phases. Man-Hour could be used in some project. But, almost in all the EPC Projects, weight value calculation is not a straight forward process and using the mixture of Cost and Man-Hours is an INCORRECT practice.

For example, on the attached table, the weight value of Engineering and Construction are based on M-H. The Procurement packages and EPC phase’s W.V are based on Cost! This mixture is an INCORRECT practice.

Some practitioners might try to use M-H for EPC. This is INCORRECT as well. (Why?)

The weight value is not only having some percentages next to the Project items (deliverables, disciplines, phase, etc.). They are systematic calculations and cannot be an amalgamation of different types of the variables.
