Oak framed garage - Slab spec

[digerjones]

hi all,
i've been asked to quote for garage and stable slab. they are both oak timber frame buildings with tiled roof. i've done plenty of slabs before, but the customer has'nt got the spec. so i was just wondering if anyone had a spec for one. i think a ring beam or something like that, not sure if i've done a ring beam before so if anyone could remind me of what that consists of i would be most grateful.
p.s. great site, thanks in advance

we did one for a oak garage the other week, put a normal 600x600 footing in came up in brick work due to level changes then cast a 150mm reinforced slab to make the floor for the garge. then we came up another 300 in brick for the garage to sit on. speak to the client as they should have a full spec from the garage manufacturer.

realistically mate you need a structural engineer to specify this

thanks men for the quick responce. i've emailed the stable company for their spec now so if i dont get any joy i can always price it like a normal slab with steel and fibres in it like giles has done on his example.

you will need links, bob bars and lacers at maybe 200 centres to form a ring beam. you can pre fab it and lift it in with a 360, or build it in situ which is more difficult. if it is only a small one you might get away with mesh and u bars to strengthen the end of slab.

just to let you know i've received spec off timber frame company. all i've got to do now is work out a price, it looks quite complicated. the slabs sraight forward just thicker where walls go and steel between walls, i would have thought the steel would have gone under the walls but this is not the case. where upright oak post go there has to be a hole dug out with concrete in bottom then i think you fill round post when errected.
