I usually keep Direct Manpower to calculate the Weightage per dicipline or activity, which includes all the personal working under supervisors like the foreman, technician , helper, equipment (JCB, Crane etc) operators, etc.
But I dont use the Equipment (JCB,Crane etc) hours to do the weightage calculation ie it wont be included in the Manhour calculation for each task.

1. Manhours are manhours and equipment hours are equipment hours; they shoudl be kept separate. The reasons is this when you will do the PF report then the earned hrs should be compared with the manhours incurred (timesheets coded to that work).
2. Most companies consider Foreman hrs as direct but please check it in your porjects estimate as where the Foreman and General Foreman hrs have been accounted.
So when you say " Manhours = Hours of Personals used to the Work +Equipment Hours used to do the Work ".
and its not "Manhours = Hours of Personals used to do the Work " - which is the total hours of personal required to do one Unit of the Work (which includes all Labor, Technician, Operators of Crane etc)
So inorder to get this table the Manhours should include "Personal hours used to do the work + Equipment Hours used to do the work"
Just for clearing it up Example : " The Pipe is not on the trench it would be above ground" which would require crane to hold it up whith the joining pipe so as to weld.
The usual procedure is to set up a composte gang resource including all the time cost related resources.
Then select 1 resource as the output driver - in this case the welder - which comprises the time for each of the 3 weld phases per inch diameter plus 2 20 minutes cooling time.
This is then converted to 1 weld per 18 m of pipe which is then converted to an hourly output of xm per hour.
If you are using automatic welding then the output would be much quicker.
BTW - the crane doesn't hold the pipe when it is being welded - the pipe is laid alongside the trench and then clamped into the next pipe for welding. The cranes then side lift the welded pipe length (1km) into the trench.

Hi Jithin
I suggest, keeping direct labor hours and non-labor separately.
