Man-hour Control

[Umerfarook]

Hi All

I am develpoing a man-hour control procedure for an engineering consultant company. I would appreciate if anyone of you guide me or send me the procedure. Following is the scenario

1. Company got seven engineering disciplines (Process, Piping, Electrical, Instrumentation, Civil, Vessel, Mechanical & utility).
2. Every discipline gets a budegeted Man-hours to carry out engineering for an EPC project(say piping 45000MHRS, Civil 22000 MHRS and so on).
3. At end of every month a detailed report is required to colculate the manhour spent by individual disciplines and percentage progress achieved.

I am looking for the procedure of "How to control Man-hour" and also "Manpower projections" till end of project.

I hope you will guide me in setting up procedures. Looking forward for ur cooperation.

Merci in advance

Cheers

Well, in general, manhour projections should be tied to a plan/schedule. Earned value measurements can help quantify how close the plan relates to the manhours that have been spent.

If you are just allotting manhours without tying it down to measureable work packages (tasks in a schedule), I think you will have great difficulty figuring out how to interpret the manhours that get burned (spent).

I can offer an excel sheet developed to work out Underground drainage system for construction activities on man-hour basi. Are you an engineer by the way?

Hi Researcher, welcome to the forum.

Feel free to post your Excel sheet in the templates /files forum if you like.

I would suggest the following when attempting to colate the man-hours required to undertake engineering and project management activities.

1.0 Use the RACI chart.
The R identifies the resoponsible person for the specific activity, the C who needs to be Consulted. The A who needs to Approve the document and the I who needs to be Informed.
Each element represents time spent E.g. A P&ID for a process stream will require some input from all parties.
2.0 Identify Design status using Ulman Diagram
All multidisciplinary engineering design effort is complex due to the 'Combinatorial effect' and the iterative nature of engineering design.
3.0 Level of Proven technology being applied
Developmental and prototypical work is obviously going to be more lengthy
4.0 Identify Level of Quality Control required
Again the quality of the design deliverables will vary hence the man-hours. If a design is fit for purpose intended and the process is relatively inert then the quality of the design deliverables may be satisfied by random sampling. If the drawings are used in the Hydrocarbon or Nuclear industry then the level of quality will of course need to be far greater.
5.0 Productivity
If the Basic Design scope is clear and the designers remit is to undertake only Detail Design then he can estimate the necessary hours based on the productivity measures within his organisation.

The final variant is of course design change and creep. The man hours associated with these will in most cases be recovered however the extent of rework will mean that some design effort will be applicable and some will be abortive.

I do have my own 'Norms' for estimating man hours.

Hope this helps

Dear Geoffrey,
I have read one of your posts dated 22may2009 where in you have mentioned that you have some manhour norms.

I work as a project control engineer in Essar Engineering services limited and work on various hydrocarbon, steel and power Projects. These projects are mostly inhouse projects.

Request if you can forward the norms so that I can work as a better proffessional.
