Calculate time

[Nygge72]

Hello carpenter. Help me calculate the time it would take for one person to install:
- Västkustskivor
- Panel
- Lay råspontluckor, roofing felt (rubber?), sheet metal roof (click)

That is, weatherproofing.

On a house approximately 12x9m (1 1/2 story with raised wall line) with a 38-degree pitch, where one of the short sides mostly consists of a glass facade.

I am planning a construction project and am wondering how to estimate the time in hours it would take to complete these tasks and how much time you would allocate for them.

It depends on who is doing the job. In other words, how knowledgeable/skillful they are.
Additionally, it depends on how many people are working if there is someone who believes you shouldn't/should/can't do it yourself.
It depends on what tools are available and how experienced the performer is in using them.
Finally, and more importantly, it depends on exactly what is included in the assignment.

So it's very tricky to answer.

I wonder if the best way to get an answer to the question is still to request a few quotes.

Now you might need to read the question again 😁 The question was how many hours a carpenter would have estimated for such a job. Then I understand that if I am to do it myself, I must add x time, as I do not have the same experience.

You might need to read the question again. 😁 The question was how many hours a carpenter would estimate for such a job. Then I understand that if I am to do it myself, I must add x time, because I do not have the same experience.

You might need to read (again?) the answer. 😁

I maintain that as the question is posed, it simply cannot be answered because there is a lack of information about various conditions.

Should one first assume what is being asked and then answer? One can, of course, but then it is unlikely to be the same assumptions that the questioner envisioned, or that the questioner forgot to consider, or conversely that something is missed that the questioner accounted for. It becomes a series of guesses that would form the basis for more guesses. In that case, the answer becomes less relevant. A guess. Probably completely wrong. Since the conditions are not known, I believe that the question cannot be answered satisfactorily.

The answer that I think is obvious in a situation like this has already been given to you: Get a few quotes.

Should one first assume what is being asked and then answer? You can do that, of course, but it probably won't be the same assumptions as the questioner intended, or what the questioner didn't think of, or conversely that you might miss something the questioner counted on. It becomes a number of guesses that would form the basis for more guesses. In that case, the answer becomes less relevant. A guess. Probably entirely wrong. Since the conditions are not known, I believe the question cannot be answered satisfactorily.

The self-evident answer in a situation like this, which you have already received, is: Get some quotes.

I understand all this, but I'm not looking for an exact time. I want to know if it involves about 1 week, 3 weeks, or 2 months to do these tasks for an experienced carpenter.

As an ordinary hobby carpenter, I understand that there can be tasks that extend the time. However, the time says a lot about what I need to plan for in terms of finding a good time of year to do this, so there is room for margins.

The idea, of course, is also to ask those with expertise if there are things to consider or how to solve certain things.

I'm not entirely clueless and have quality tools, as well as knowledge around for help if needed.

Calculated on a gubbe, I would have said approximately 3-4 weeks for the west coast board + panel between the little finger and the elbow. Provided that there is scaffolding.

The roof approximately 2 weeks.

If there are two people, it becomes more efficient.

Now I am an amateur. But I guess a skilled carpenter could fix what you've listed in about 2 months. However, a lot of time can be spent just carrying materials, so if the materials are more than 5m from the work site, you might need to add quite a bit of time for that. As for that metal roof, I have absolutely zero knowledge of how long it might take.

But if we consider the roof. You likely have some penetrations, e.g., for ventilation. I think you might have to add roughly a day for each penetration. Fasteners need to be mounted before the underlayment, the underlayment has to be pulled up on the fasteners, holes need to be made in the metal, various overlaps on the metal, etc.

And there will be similar "deviations" on the walls where a single detail adds 0.5 - 1 day extra per detail.

And if you only find an ordinarily skilled carpenter, you might have to add 50 - 100%, and double it again if you get ahold of someone really bad.

And handling of materials and waste can take at least as long as the construction itself, unless it can be organized very efficiently.

I have absolutely no knowledge about how long that metal roof can take.

But if we take the roof, for example. You probably have some penetrations, like for ventilation. I think you generally should add about a day for each penetration. Mount fittings before the underlay felt, the felt should be drawn up on the fitting, cutouts in the metal, various flashings on the metal, etc.

And there will be similar "deviations" on the walls where a single detail gives an extra 0.5 - 1 day per detail.

And if you find just an ordinarily skilled carpenter, you should add 50 - 100%, and double it again if you find someone who is really bad.

Fine. Now I at least have something to start with in how I should think. As a former trained chef, I know all about preparation, that it's the be-all and end-all if things are to run smoothly, which I always incorporate into my projects, and it almost becomes my downfall because I never get the small breaks that otherwise occur naturally when fetching things, etc. 😂

But the key is to find the right craftsman. In the countryside, an "attefallshus" was built on a neighboring plot. There were 4 - 5 men on the construction site every day, from May to September (the foundation had been poured the previous year). At that point, the windows were still not installed, and the paneling was 3/4 finished. As far as I could see, the walls were insulated, but nothing was done on the inside. They installed a metal roof, with 3 guys managing to place 1 - 2 metal segments per day.

There were 4 - 5 men on the construction site every day, from May to September (the foundation had been cast the year before). Even then, the windows were still not installed, and the paneling was 3/4 finished. As far as I could see, the walls were insulated but nothing was done on the inside. They mounted a metal roof, 3 guys managed to get 1 - 2 metal segments in place per day.

Pathetic fraud. Then I can compare with the neighbor who built a 1 1/2 story house where 2 carpenters (besides during roofing when they were 5 and laid the metal roof) were involved. He built with pre-cut, but it was weatherproof + garage set up and weatherproof with windows etc., in 1 1/2-2 months.

Pitiful swindle. Then I can compare with the neighbor who built a 1 1/2 story house where 2 carpenters (apart from the roofing when they were 5 and laid the metal roof). Now he built with pre-cut materials, but it was weather-tight + garage erected and weather-tight with windows etc., in 1 1/2-2 months.

There you have more or less answered your own question, at least approximately😃.

 

[Nygge72]

There you have pretty much answered your own question, at least roughly 😃.

No, because they did a lot inside the shell as well, which I didn't see 😁 However, I did notice that even these cheated with the time. 2 hours that the neighbor had to pay for each day they weren't there. Arrived late/left early and the same at lunchtime.

2 hours that the neighbor had to pay for each day

But it can be difficult to assess, if you are an outsider, travel time is included in billable time.

 

[Nygge72]

Though it can be difficult to judge if you're an outsider, travel time is included in billable time.

I'll leave unsaid what they agreed upon, but he wasn't happy when he got the invoices and they did it this way. He could accept that it was travel time when they came in the morning and finished in the afternoon (but if you're paying for 8 hours it should be 8 hours of work you get, then they could have added travel time on top of that), but that they would drive off and eat every lunch instead of bringing a lunch box and he had to pay for an hour, he was less pleased with.

There are probably few other jobs where you can come 30 minutes later and leave 30 minutes earlier and get paid for 8 hours (+1 hour at lunch).
