60ft wide grain store/silage clamp

[dannewhouse]

I'm going to put a building up this year to store grain and the mill etc and some protein bays. I need 60x60 but I'm hoping to put up 90x60 or even 120x60 depending on £££ but I can see that in a good few years this building could be used for a silage clamp. I only have 8ton trailers at the moment but it needs future proofing. I was thinking I want 20ft at moment but probably higher for a clamp?
What will my extra costs be like?
6" pannels am I better in 15 or 20ft bays?
3m high? Metal profile sheeting, fibre cement roof on wood purlins?

I do everything with 20’ bays now,quicker build times etc
Some will say timber purlins sag but if you use seasoned timber they don’t,I also prefer fibre cement over tin,heavy work sheeting but a better roof,also have a 17.5degree pitch,means the centres higher for tipping.

Does 17.5 not cost a bit more, how would that compare to just making it a bit taller?

Yeh 60’ wide would be decent, then you can put a dividing wall down the middle and two big doors at the front left / right.
In hindsight I regret doing mine 50’ wide with a central 20’ door, it’s a bit of a pain swinging machinery in at an angle and it’s not quite wide enough to have a middle grain divider.
20’ eaves height is okay for me

What about future possible change to silage

This might be not the best idea but access will be through the side not gable end, I will extend the roof to create a shed for straw/machinery and grain will be best at the other end. It's in a corner of our land/yard I will be putting it. So 1 side and 1 gable closed in for definite.

Have this available, 36m x 26m reduces to 20m,

To future proof I would be going higher than 20ft eaves on any grain or silage store built today.
A fully tipped 12t tonne grain trailer is about that height and 14-16t is average size sold today never mind tomorrow.
Generally been building anything here in recent years 3ft higher than I think I’ll need.

I was thinking 28ft would be nice?
At what cost am i future proofing this building?

If you want to make it usable as a silage clamp in future, you will need far bigger steels than you would for a ‘normal’ barn. If you go down that road then extra height will be much more expensive than it would be for a conventional portal frame.
My grain store/shed here is 120’x60’ and 20’ to the eaves. I tip an 11t trailer against the side without issue and can have tipped bulk lamb creep in 8 wheelers with plenty of room. Nice to have the room to load 20t loads of corn under cover too.
I don’t know your scale or ambitions, but are you likely to be wanting to tip artics in there in the future, or ever likely to be running 250hp Fendts and 18t trailers?

250hp 18ton probably not,
Artics possibly.
Clamp will need bigger steels than a normal portal, but won't a grain store any way?
Or is it grain store needs a bit bigger, clamp a lot?

You can manage to tip a artic in a 22 ft eaves height shed if it’s grain,and floor of trailer is shiny
weve a few 25ft high and there better still

Surely you will need headroom for the claming machine more than tipping trailers?

That's what I was thinking, nearby farm has a 60ft clamp, only looks 20ft to eaves to me, 3x1.2 pannels and yes they bang the roof of. Buckrake tractor!
Alternative is 20ft but only 3 1m pannels? But still be tight. Or don't fill it to max hmmm ...
