Not stupid at all - the mini / crazy courses although covered with a smooth putting felt are all basically contoured concrete platforms
Here's one in Hastings before the felt is laid
Dave_L - if we need to factor in some extra concrete, do you normally have a rough 'rule of thumb' guide of the extra % it might need?
its called a contingency stoichkov, on a job like this you would probably have a 5 % contingency to be agreed with the client ,architect,and builder
also would probably be 2.5% retention for 6 months
when the digging starts there are all sorts of things that can crop up that could add to the cost
but if using concrete or bitmac you really need experienced concrete finishers/tarmaccers for this sort of thing
I wonder if the yanks have this sort of thing in kit form?
they love a bit of concrete

I understand the contingency idea, but whats a retention?
Is that some of the contract value withheld until a set period following completion of the work?
a retention is a percentage of the contract value withheld for a period of either 6 months or 12 months to cover any defects what may arise with the work
for example this percentage can vary from 2.5% to 5%, its what ever has been agreed with the contractor and yourselves before the work commences

What do you guys reckon about damp proof courses? One possible contractor specifies them, the others don't. I can see the sense in them, but do they do their job?
The other thing is soakaways. Again, one contractor (who has built courses before) is adament they are needed but this would involve quite a bit of extra excavtion to accomodate them. Our site is about as free-draining as you can get - It's never been known to have any standing water or flood at any time. We'd plan to have drainage holes at key points around the surrounding bricks and would sink the actual 'golf hole' nice and deep. Some water could drain out the sides into the grass but most would find its way down the main hole which, in effect, is a sort of soakaway anyway?
I take it you mean damp proof membrane as in visqueen sheeting underneath the concrete then yes I would put it in
dig a few trial holes dotted about the site 400mm x 400mm x 400mm deep and fill it with water, if it disappears in a few seconds then you should not need any surface water drainage, if it takes hours then yes you will need soak a ways for your drainage because I am sure you don't want to be handing out wellington boots to your customers just to play a round of crazy golf :;):

constructing the holes with a concrete base is not required.the modern artificial putting or lawn turf manufacturers will tell you that.the turf is porous.there is a spec for the sub-base construction to ensure it is self draining.
presumably you've putted on "felt" surfaces,with a concrete base,you see on some crazy golf courses and realised that they are crap?
the idea with the new adventure golf courses springing up is to create a fun and realistic putting experience for all the family,not just the kids. choosing the correct materials for this and speaking to contractors with experience of laying these materials is obviously key.
very nice stoichkov,there is something quintessentially British about crazy golf,although i have played them in other countries
i like the ones with tunnels where the ball disappears briefly

my constructive critcism would say, wheres all the water going? too many straight lines. too much concrete materials on show. too flat. too few natural contours.
looks like you did all the research,had a picture of what the course should look like then took nothing on board and did the opposite!
did you forget that you only get one shot at these things and if its crap the punters dont come back?
touche!
its not finished yet bobbi,but i have to agree it doesnt look the finest just yet
more pics stoichkov when its dressed up a bit mate
cheers

When we had some heavy rain around easter, the builders looked at where the water was pooling and then contoured it off gradually to take the water away. The upshot is that the course doesn't have any standing water on it during periods of rain.
There will be additional planting around the holes and we've got to add the wooden features last after the green felt has been laid.
As its in a conservation area, we were restricted in terms of height etc but we think that the design of the holes in how they play makes up for this.
I'll stick some more pictures up after it's finished..
