Slurry Store dismantling.

[Wreckit Ralf]

We've been offered a good condition slurry store, around 250K gallons, for nothing at a farm local to us. What would be the rough cost involved in dismantling and rebuilding? is it worth it compared to the cost against new?

How much do you value you're own labour as it's only time really???
A couple of rattle guns and family labour and it would be well worth the effort but maybe not so cheap if had to employ a team.

I helped dismantle one a few years ago.

Telehandler with a strap and 2 tiny shackles for lifting the panels.

Cordless impact gun, 4 men and a digger with a breaker for getting the bottom ring out of the ground.

Nearly all the bolts came undone.

1.5 days.

I was offered a 300 gallon one taken down for 10k.
Cost of a team to erect versus new price, new won the day by a country mile.

I do it sometimes. It has to be really good condition, and later ones were built with Sikaflex mastic, meaning it will still be standing if you take all the bolts out, but easy to damage the glass trying to separate the sheets. Replacements can ruin any savings. You will need mastic and replacement nuts, bolts and washers from me. The cost of base and erection are the same as new, so don’t expect a massive saving.

Not that I’m thinking of doing it but out of curiosity, is there any reason why nuts and bolts can’t be re used?

Used bolts and nuts are a pain because some will not tighten up freely, needing to be changed, or held, damaging the head. If I were putting it up, it would be cheaper to pay me using new bolts, nuts and washers, than to re-use them.
Technically, a bolt that has been tightened once has different characteristics to a new one.

Again, idle curiosity but how much is a new nut bolt and washer given that they’re a specialist bolt? There must be thousands in a tower dependant on size !

 

[MickMoor]

A lot cheaper than you could buy ordinary nuts and bolts, actually, but please note these prices are for bolts in multiples of 250, nuts in multiples of 1,000 and washers in multiples of 2,500. If I have to open boxes, count them out, store some loose ones, the costs per unit are more.

As you say, cheaper than I’d have thought........,,......that said, 1000 don’t go far on a decent sized tower.

You are right about quantities. I have sold over three tonnes so far this year. Exporting to Sweden, Latvia, Croatia and Ireland, as well as a few in this country. Enquiry today from SouthAfrica, but have my doubts as he only wants less than 10,000, so the paperwork might not be worth it. I will have to send them sea freight, or costs will be more than they are worth.

 

[Wreckit Ralf]

Thanks for the replies. By the sounds of things, with the hassle involved, the cost against new doesn't make the 2nd hand tower worth while. Still considering a lined lagoon as it would be a considerable saving over a tower?

 

[MickMoor]

I don't need the work so this is just to make you aware of the pitfalls. A lagoon has much greater surface area, so will collect more rainwater. This could be good or bad, depanding on your system.
I have posted elsewhere that if you get gases given off under your liner, it will float reducing the capacity considerably. That would be heart breaking.

I have at grain silo to dismantle and was looking for some advice/tips on how to split the sheets once we have removed bolts? I’m guessing the mastic will be a b**ch to remove! Any help much appreciated!

Shouldn’t be a problem, they flex to break the seal,
How you dismantling,
Easier to lift through top hatch, (wheel /tyre) on a 12m telehandler, split at bottom ring, then work bottom up wards, take of roof, before you split last ring,
Say a 150 ton bin, two men, two battery impact guns, 12 m telehandler, 1 day , to dismantle,
