I would need some ideas and opinions regarding a renovation of a ramp at the summer cottage. The ramp is built from pressure-treated wood and much was replaced a couple of years ago, some beams have been replaced. With the purchase of a larger ATV, it became necessary to check the condition of the ramp, as it feels a bit shaky in some places.
The ramp is extremely important to us as it is how we access our house.
The purpose is to stabilize the ramp so that it can support an ATV weighing around 400kg + driver, as well as a trailer and load. So, I want it to be able to carry about a ton without any issues.
As you can see in the pictures, the ground conditions are rocky and sloping. It is filled with crushed stone under the ramp. The ramp itself is built on an iron frame that is somehow cast into the crushed stone, but much of the concrete has broken down, as it is after all probably 30-40 years old.
You can also see that the iron frame has bent in some places so I think it needs to be completely replaced. As a temporary solution, I have put a couple of poles on garden slabs to strengthen the construction somewhat.
How would you stabilize the ramp?
Cast new piers along the ramp and replace the steel with sturdy wooden beams? Essentially replacing the entire steel construction with wood?
How much work do you think it would be for a carpenter to fix this?
It is probably cheaper to tear down and build new.
You need to have a constructor calculate it. To get bids from carpenters, they need a drawing to work from, and no serious carpenter will build that without someone having calculated it.
If you do it yourself, you need to determine if you can do it safely. It is not difficult, but you need to think it through as it is really dangerous if it doesn't hold.
A ton isn't excessively much, right? That's at least what a regular deck should handle?
They're usually dimensioned for snow load in normal cases unless you plan to have a spa or something similar on it. The snow zones 1-5.5 provide 1-5.5 kN/m2, which is 100-550 kg/m2. How much does the ATV weigh?

It is probably cheaper to demolish and build new.
You need to have a structural engineer calculate it. To solicit bids from carpenters, they need a drawing to base it on, and no serious carpenter will build it without someone having calculated it.

Thanks for the reply! Just so I understand, what makes this more complicated than building a regular deck? Is it the foundation that complicates it? The dimensions of the wood are well-considered, cc distance, etc., on the existing ramp.
My idea was to cast new pillars along the outer edge of the ramp and install sturdy carrier beams attached to the rock.
You are driving an ATV with a trailer and load. If you tip over and get the machine on top of you, you can be injured for life or die. So be sure of what you're doing.

Yes, absolutely, it's of course important that it remains stable.
Thanks for the response! Just so I understand, what makes this more complicated than building a regular deck? Is it the substrate that makes it difficult? The dimensions of the timber are substantial, the centre-to-centre distance, etc., on the existing ramp.
My thought was to cast new concrete bases along the outer edge of the ramp and install heavy beams attached to the rock.
In the pictures you have posted, it looks like the wooden construction is both well-dimensioned and in decent condition. It should be possible to cast new foundations/bases beside the existing posts if the ones you have are bad and then install new posts and supporting beams against the rock. Whether they should be wood or steel depends on if you are doing it yourself and what knowledge you have of welding, etc.
In the photos you posted, it looks like the wooden structure has both the right dimensions and is in decent condition.
It should be possible to cast new foundations/pillars next to the existing posts if the ones you have are bad, and then place new posts and supporting beams against the rock. Whether they should be wood or steel depends on whether you're doing it yourself and what welding knowledge you have, etc.
Thanks for the response. That's the solution we're aiming for. I'll update the thread on how it goes in case anyone is interested.
Have had a 'local ability' that has now started to stabilize.. what do you say about this? No beautiful posts which I don't care about, the most important thing is that it becomes stable.. the ground consists of a lot of loose stones in mixed sizes, feels like they just threw the concrete on. But maybe that's completely fine. What do you say @Testarn
It will definitely be much better and more sustainable 😊
That sounds promising. Yes, it seems like the prerequisites are there at least. How would you attach the beams to the rock, drill in a post base and set the beam in it? Or would you, if possible, attach a piece of 'bärlina' to the rock using something like expansion plugs for the beam to rest on?
The beam comes towards the rock at about a 90-degree angle...
