Dear Friends

 

Today I got a new thumb rule from my manager

That is 22% of the project cost is the Budgeted manhour.

Is this statement is correct .Please help me my dear friends...

Arun,

Its cost, i.e. divide by presumed hourly rate gives hours.  As Anning said, take it for what it is.  A rough rule of thumb when no other methods of estimation are available.

Cheers,

Chris Hall

Dear Friends 

I am not getting his logic...

Both are different units..

If the 22 % of project cost is Manhour cost then it is ok...

How the 22% of cost will be the manhour??????

Arun,

It depends on where and what the project is.  We use a 'rule of thumb' from 60/40 - 70/30 for general construction projects.  Different ratios for offshore, regional, energy & mining and of course if the project has IEP requirements.
