how chiedo?

[Iena]

Good morning, everyone.
I am in negotiation to bring home a project. It is about designing a plastic film wrapper/winder. I would give the customer the whole project "turnkey" complete with electronic part and sucessive collaboration for commissioning the plant. to large lines we talk about plants from 100,000 heur.
for me would be the first time as external collaboration.
but I can't be more detailed today.
at the end of my question is this: "How much can I ask? "

 

[Fulvio Romano]

100,000 heur question!
usual advice (given several times of different threads). split the work in phases, estimate the time for each phase, multiplies by your hourly cost, multiplies by a security factor (do not exaggerate!) and see how it comes out. from there you start to reason. . .

This is my approach, but not everyone agrees

Okay.
two more things: the security factor, how much do you consider? (2,3)...... Hourly cost, what is the average of a free professional?
Hi.

100,000 heur.
No joke.
is just the suggestion of Roman lightning
other shortness.. .
since we talk about multiple stages of work
- mechanical design at a quote net of changes in working time that will be invoiced on the basis of tot euro/hour.
-project or electrical advice on the basis of Euro/hour tot.
- support in assembly fae absolutely to consuntivo based on tot euro/hour.

If not you risk a bloodbath.
those who ask for such a complete quote and because they do not have their own mechanical or electrical (there will be a reason) and often in good or bad faith tend to simplify the work of their collaborators.
for the rest if you use search you will find fior fior of discussions and opinions.

Hi.

by security factor I mean 10%-20%, depending on how much you cut with the accept to make the quote

 

[Strumpf]

these "phases" very often and willingly multiply, repeat, and slow down, because the customer makes you make changes on changes, and then you struggle to distinguish changes from corrections (corrections don't pay them)
so I highly recommend you to agree on an awful price and make you pay at the end of the month the tot hours you have done.

Watch this definition. ..."keys in hand" hides many pitfalls and big surprises.
I share the other answers.
with these types of project I recommend that you anticipate 10% and at the end of the month you pay with respective invoice.
if the customer does not accept your proposal, think well before making a closed price.
often happens that the time you had predicted doubles.. And I see it hard to make you recognize it.
how much to ask at the time is not answerable... who proposes from 20€/h to 50€/h.
the important thing is not to sell out.. . .
Good luck

thanks to all for the precious advice

another way to quantify your work, besides those already mentioned and all shared, is to define a percentage. If the work consists in designing something you know the final cost, you could assume as compensation for the designer a percentage on the work. the question at this point is: what percentage? I do not know how to answer this question, but I believe that the professional alibis of engineers or experts foresee such remuneration and therefore also fix percentages according to the value of the work. could also be adopted in other areas.

But you finally got the job? ?
And the money? ?
How did you quantify this? ?
