how to make a quote for carpentry

[raed]

Hello everyone, I'm new to the forum.
I introduce myself, I am raed a 23-year-old boy who does the 2d technical designer for 2 years and who will begin a solidworks course shortly.
I decided my father and I to open a metal carpentry.
My father has been in the industry for more than 34 years with so much experience in assembly (shafts, turbines, hydrogen cooling group, oil rigs etc) ranging from 1t even up to 100t of weight.
The only problem is that we do not know how to anticipate a job.
Do you go to kg? at hours? how to estimate the execution time? gain? material cost?
I have seen that with solidworks it is possible to estimate how much welding kg etc. but can you also estimate the time?
I know perfectly that I'm very vague but I need a hand that I'm really excited about this project and I'm trying to study as much as possible but I can't find an answer that can understand it well. Thank you.

hi, I know it's been a long time, but by going through the forum I repeated this conversation and, as in the company I take care of these things, I wondered if I had resolved or if I were still looking for some solution or advice. Let me know.

even without the request of raed, which after this message is gone, you could still bring your experience on the forum that will certainly be useful to some user

absolutely, I bring for example my personal experience.
I deal with railway armament (to understand us mainly exchanges, and all that concerns the "where to pass" a convoy), and certainly in the first place from the raw material, in my case the material (steel) for plates, platelets etc. and rails, all in kg. therefore according to the individual design and the various dimensions plates and lengths that serve we already know the cost of the material that serves.
for the processing the speech is similar, but slightly more complex: I have made an excel sheet where I insert all the workings you need, putting the time used by every single worker in minutes, which multiplying it for the hourly cost divided 60 (cost per minute) tells me how much that single processing costs me, of course including moving parts, various centerings etc. With regard to the details provided by external companies, knowing the price of each retail component, this is multiplied by the number of details they serve (for example, a vine costs 1 euro, needs 100, 100 euro of vines).
in my sheets I also added a possible depreciation of machinery or other items, which are usually not considered.
at the end you add the whole and you have the cost of producing a certain thing.
so I admit that it seems to be the easiest thing in the world, but when it is actually done, it is definitely lost in time: That is why I created a "universal" sheet where I only change the prices and the number of pieces that serve for various exchanges. Obviously something like this is useful to me, that more or less exchanges always have the same pieces, but of different sizes. and underline that this serves only and exclusively when you buy everything; Instead, I am processing a change to these sheets to take into account the "funds of warehouse", or pieces maybe advanced by previous orders but still usable.

I remain available for any questions.

Hello, raed, do you still need clarification? if you are available.

 

[Giacomo101]

I connect to the conversation, if you have any experience to bring in the forum all the tips are well accepted!

only carpentry:
2€/kg (boxes+welding+handling+customs)
5€/kg ( laser cutting+folding+welding+handling)

only carpentry:
2€/kg (boxes+welding+handling+customs)
5€/kg ( laser cutting+folding+welding+handling)

depends also on the artifact... if for example it is light and composed of tubular the cost increases.

It's a little high. depends on what you do and who you turn around.
up to pre-covid carpenters 1,20-1,30€/kg all stuff cut oxytaglio, assimated and welded....also plates 150 mm thick and cords 70x70....poi 2-3€/kg for laser cutting and bending stuff.... however some pieces cost a barrel per kg if they required a lot of time to place particular.
is always to be evaluated material, hours and labor, depreciation, various costs.
attention that many do not make you work at those prices.
