Man Hour Estimation

Hello josej

I cannot see your particular documents.

You do not list your Location, or Country, which is easily done by you, in your Profile, and then it auto-updates through all your Posts and Topics.

Location and Country is helpful, particularly with a Topic such as you have Posted above.

All Manhours are broken down, and by experience a Professional Estimator is able to break down into basic steps, then quantify each small action in each step of each Instrument, Metre of Cable, or whatever Hardware part/s is/are to be installed.

Tenderers for such a Project normally have wide experience, plus a set of carefully maintained, updated, and secret Company Tables already to apply for each Tender they actually attempt.

Without more Specifics from you, it is truly difficult to advise you in any way other than the above.

Yap, its right and the first action is identifying how many item & type of instrumentation that shown in PID. Next you can breakdown for each item with following related document to be prepared and issue for Client approval. Some of project needs three sequences for getting approval, i.e. IFC (Issue For Comment), IFA (Issue For Approval) and AFC (Approved For Construction).

Let's say you identify one Local Pressure indicator. The following document need to issue and approval is Specification, Data Sheet, Material Take Off, Requisition for Quotation, and Technical Bid Evaluation. Each particular document has different consuming man-hour.

Prepare table for estimate the man-hours:

So you have summaries man-hours for one local pressure indicator.

Hope answers the question.

Save the earth, please consider the environment before printing this sheet

Ynnor,

On your reply there is a table with estimated man hours. Do you know anywhere that I can find Standard Man Hour Norms by engineering discipline. I have been tasked with designing CTR Norms and I am missing estimated man hours for different deliverables within each discpline. What I have been searching for is an industry accepted standard norm by man hour for deliverables. Is there anything like that out there?

Thanks,

Mike

Hi Mike, Unfortunately I could not found any specific norm. Trust that CTR norm will be based on individual experiences. This is pretty much similar with the others that they maybe add some factor to justify. The best you can do, upon complete the project then recap whole burned hours into one compiling man-hour table then categories into each discipline and doc's deliverable. The objective of CTR is to making competitive cost estimate which each of company will proceed with their strategy to justify their final price. Regards, Ynnor

Sparkstation is right on...not enough info. However, if you at least know what steps need to be taken to complete the project and you can estimate approximately how long it will take to complete each step you might try the "Microsoft Project" software. If you know those two basic pieces of info, "Project" will guide you through and produce a Gantt chart and your project will begin to take shape in a logical form and progression. That's what I use when I have to manage a project and its a very easy program to use. Never fails to make the "big dogs" happy. Hope that helps a little.

Some might suggest that the above is its only purpose: to beat people up with when those bars start shifting to the right.

I use an Open Source veresion, OpenProj, that does much the same thing. The smaller the steps you can break the project down into, the less accurate each step estimate has to be. That is, a project of 10 tasks needs to have each task evaluated much more accurately than a project of 100 tasks...Experience is the key to getting good time estimates...

Dear Frnds,

Thanks for all the Info

The above statements are true - They do not get the job done!

You may need a guild for your needs.

As it is commercially-sensitive information, it may be <...out there...> and it may not be possible to locate it from <...there...>. There must be similar available from earlier projects at the facility to use as a basis, surely?

It's a table. As there is arithmetic in it, perhaps a spreadsheet platform would be the best foundation for it, as altering one figure at the top will automatically and instantly change the calculated figure at the bottom.

Engage a local Mentor at the facility for help. The consequences of getting it wrong could be expensive.
