    Alternatively, a swing gantry with DC, AC and Air could get you to almost any location (albeit, only one location at a time)

    The timber floor idea is great but way over my budget The gantry idea has potential though and I'll give it some thought if the concreter wants too much to add the trench. An arm pivoted on the wall with an elbow in it could be positioned over just about any of the machines but one of the things I want to get rid of is leads and hoses hanging all over the place - would much rather the services be close to the foot of the machine

    Gantry will be OK for Vacuum cleaner hose but using too much flexy on a DC will throttle air flow especially on 4" ducting

    don't know your budget, but done properly, a 250 x 300 trench in the slab -- about the size you will want to carry DC piping, air and power -- will likely cost heaps in terms of additional steel and labour.
    in structural terms you would be moving from a slab floating on the ground to something akin to two wings held together and in position by the trench -- which implies relatively heavy reinforcing through the trench and many man hours tying steel bars to bar chairs and mesh reinforcing
    the alternative is two separate slabs with a gap in between

    My guess would be the raised wooden floor would cost the same or less than the trench....

    I'm with Chambezio, put the ducting under the slab with risers wherever you think they might be required in the future and then lay a smaller diameter services pipe alongside. The ducting can be fitted with covers that are flush with the finished concrete surface. You would need to have a look at what sort of covers are available from a plumbing supplier.
    This would be heaps cheaper than a floating timber floor or inbuilt trenches.

    Default Update!

    Didn't realise how long all the legal carp would take on a block in a new estate - what the hell is there to search for!!!!!

    Anyway, the land is finally ours and the builders will start levelling for the slabs next week so I got to talk to the concreter at last. No problem with the trench He's done this sort of thing before and it is only going to cost $500 extra which I'm happy with - couldn't build much of a false wooden floor for that!!!
    He's going to dig a trench and pour the base of it with the house-slab pour, then form up the walls of the trench before the shed-slab pour - too easy!
    Will take some pics if I can get there on the day but it will be 4 or 5 months before I get in there to set it up and use it - how long do they hold a thread open for editing???

    Default Update!

    Back at last! It's taken all this time to get the plans through council and for the builders to make a start but the shed slab is finally poured and regardless of all the good advice here I've gone for my service trench idea anyway It's costing me an extra $500 but I'm sure (hoping!) it will be worth it not to be tripping over leads and hoses forever and a day They start forming the house slab tomorrow to pour it on Monday (hopefully) - could finally be in a decent sized shed by by Xmas

    Vern, good to see the priorities are right - shed slab first

    Hope you are above the high tide mark in that new subdivision in Emerald.

    It looked "high" but photos can be deceptive.

    I think you have planned that very well
    Get the shed built before you have any neighbours who might object.

    re question regarding all the pre-settlement checks.
    It's your problem -- not the developer's -- if main roads (or the railways) have plans to put a freeway through the subdivision in 20 years time.

    Default Shed has arrived!

    Finally some progress - the kit has been delivered at last! The house is almost up to the fixtures stage but I'm not sure when they plan to put the shed up - will find out this week I suppose

    Default The new living room is ready!

    Hope to get the keys on Friday Then the hard yards start, moving all that wood, and machinery, and tools, and steel, and racks, and . . . . . .

    Ended up buying some 6mm aluminium chequer plate for less than half the cost of steel and had it sliced into 240mm strips to cover the service trench. Once I get settled in I'll screw the plates down (somehow!) and cut holes for the dust extraction hose/line etc.
