Show off your skills and solve real design problems
Come up with a new skateable art or an obstacle an win an Archos 7 Tablet. ARC is looking for new designs for obstacles to use in their skateparks all around the world. Be creative, don't hold back. They need new ideas and skaters need new obstacles to pull more crazier and cooler tricks.
The challenge is to design and engineer an obstacle for skateboarders to use for stunts and tricks. The obstacle should look funky and give give boarders variety of possibilities to pull different tricks.
Currently the most popular obstacles are tables, benches and different concrete boxes. But you can come up with totally new design / obstacle. Feel free to go crazy shape and construction wise. Don't go too crazy size wise as the obstacle should be a part of a skatepark not an skatepark itself.
If creativity is not your strongest skill then don't worry they have an engineering problem that needs solving as well. ARC wants to install a halfpipe on a sloped, grassy area. But they need ideas on how to anchor it into ground with adjustable supports. Goal is to install a halfpipe from a kit in one day. Solve this on and you could be a winner too!
That's it, that's all. Get modeling!
There are no hard requirements, besides the materials used for the obstacle. Be creative and show what you can come up with.
Obstacle should be possible to disassemble for shipping
3/8 and 1/2 hardware are used to assemble the obstacles.
Light welding may be done to assemble on site.
Steel materials to use: Laser cut steel (and stainless) ranging from 7ga-10ga. Also 1/4 and 3/8 may be used as well. 2x2, 2x3 and 2x6 tubing , mostly 11 ga. as well as 2" schedule 40 pipe.
Composite materials to use: The benches and table also use composite lumber that is 1.5"x 2" . 1/4 composite sheeting material (Ramp Armor) can be used as a finish surface not structural. Starlight XL panels, a marine grade structural panel can also be used.
Concrete: ARC has a batch plant on site and can build mold to pour 9000 psi concrete.
Winning design will be chosen based on the awesomeness, creativity and ride-ability with skateboard
The competition is open to everyone
Team entries are welcome. In case of team win, prize money will be transferred to team leader who is solely responsible for splitting it among team members
You can submit several designs
Only models uploaded to GrabCAD library will participate in the competition
Only models uploaded through this challenge page here will participate in the competition
Tag your model with “arc” to make it easier to find.
You may upload a private model but you need to share access to indrek@grabcad.com
Privately uploaded models will be made public after the competition deadline
Models can be done in any CAD software as long as a STEP or IGES files are also uploaded
Competition starts: 22rd of August, 2011
Competition ends: 4th of September, 2011
Competition winner will be announced in GrabCAD’s blog no later than 11th of September
Most creative design will be chosen by American Ramp Company with little help from GrabCAD
American Ramp Company is the world's largest skatepark provider. They have built more than 1,400 parks worldwide and are the only skatepark company that offers every build option: precast and poured-in-place concrete, steel, wood, composite, and fiberglass. American Ramp Company is the result of one skateboarder’s dream to do what he loved. From humble beginnings as the son of a missionary living in Southeast Asia, ARC founder and president, Nathan Bemo was always looking for a place to skateboard, and if he could not find a place, he made a place.

Can you give metric norms/requirements too..
Indrek Narusk over 12 years ago
Please do use US dimensions as these are the actual profiles and hardware they are using today.
ALI ALDUBAISI over 12 years ago
you mean English units?
Indrek Narusk over 12 years ago
Yes, inches it is.

Little update on the prizes. 5 top finalists will receive extra 100 USD.
Joe Birner over 12 years ago
Awesome entries so far. Amazing what
shows up with an outside point of view.
Doug Davey over 12 years ago
Looking interesting ..... Please can the give us a picter of their halfpipe and a view of the underside so we can understand their construction.
Manolis Theofilos over 12 years ago
Yes Doug is right. We need some info about the halfpipe and the area that needs to be installed.
Doug Davey over 12 years ago
Please can we get info
Doug Davey over 12 years ago
Please please
Joe Birner over 12 years ago
sorry, guys, I diddnt check these comment. I will send them shortly

Indrek Narusk over 12 years ago
We just added some images of the ramp.
Doug Davey over 12 years ago
Sorry what slope angle are they wanting or rang of angles?
Joe Birner over 12 years ago
There is a 1:1 dxf of the bottom available at the previously given link.
Doug Davey over 12 years ago
Sorry, Maybe I did not express myself correctly. The aim is to erect the halfpipe on a sloppy area. I just want to know what the max slope will be
Joe Birner over 12 years ago
I dont know, ithas just been a concept that we have talked about several times. Probably about a 10-15 degree slope. If it worked well then it probably would be done as another option to do more agressive slopes if needed.
Joe Birner over 12 years ago
STL file of the half pipe upleaded to the link above.
Doug Davey over 12 years ago
Hi Joe
If we look at the halfpipe, it is a very long system and I can understand why a level ground area is needed. To erect in on a slope brings up a number of questions and problems not least of which is at 358 feet and 10 degrees slop you have a rise of 63 feet at the far end. So any solution would be a rather large construction. I know it can be modularized but things like assess would need to be look at and heaven forbid should a rider miss:- 63 feet is not just a …………. So over and above all the rest of the problems that would be involved, is it really a feasible idea? It might be more feasible to look at the present construction to allow for such a slope, plus railings, access and every thing else that would go with such a design.
Doug Davey over 12 years ago
Yes I understand that it may be placed side on to the slope but still it would have a 16 foot drop and still major construction. I don’t think this competition has allowed enough time or ……….
Doug Davey over 12 years ago
Please advise us, …. as to your view point
Joe Birner over 12 years ago
Well Doug I dont know how to say this but, INCHES not feet. The whole half pipe is only 30 Feet long from end to end. LOL.
Doug Davey over 12 years ago
Ok ........ where does one hide ones head in GrabCad ........he he
Doug Davey over 12 years ago
OK now .... That does change thing but still in length that’s a 5 foot drop at 10 degrees. You seem to have the centre reliant on the level floor. So do you believe that what you would like to see is a framework that could be erected that would give you a level area to then erect the halfpipe?
Doug Davey over 12 years ago
And in my defense …. It’s been a long time since I work with feet and inches.
Joe Birner over 12 years ago
thats, fine. It may not have to be a Solid platform to hold the half pipe, but maybe a adjustable Frame that the Platform bases would sit on.
Alternate method would be a (post system) that would adjust a tube frame to a level height reguardless of the ground underneath.
Joe Birner over 12 years ago
I realy like how some of these incorporate multiple options into the same piece, or obstacle. Our customers are like everyone else. They Like more bank for their buck. More than one way of using the same thing.
Joe Birner over 12 years ago
I am hoping to see come concepts for the ramp leveling/ lifting system.
Neil Reed over 12 years ago
I noticed this after uploading my modles to my library as public and tagged "arc".
Only models uploaded through this challenge page here will participate in the competition
So am I ok or do they have to be re uploaded though this page? (they do show up in the entries page...but just want to be sure :-)
thx and please respond I am off on vacation soon.....
Indrek Narusk over 12 years ago
You should upload through the challenge page. But don't worry, we'll make sure all your tagged files will participate in the challenge.
Doug Davey over 12 years ago
Hi Joe
? … when the halfpipe is set up … is it set up on a temporary basis or permanent?
Boy I do not think there is enough time to get this one done ….. that’s if I am looking at it from the right angle or viewpoint.
Joe Birner over 12 years ago
Probably permanent. Like I had told someone else. I see this as having more concetual type entries due to the variance of products. I had told someone else that with all the variables, theres no way to cover ALL of them in this time frame. However Design intent counts for a lot i would think.
Doug Davey over 12 years ago
Sorry Joe ….. I have done a bit of work on the idea but am not every going to get even close in the time allowed …… so for now I am out.
Catch your next one.
Dislike having to give up …!!!
Terry over 12 years ago
I cannot find anywhere to post my model through the contest page, I have uploaded and tagged it and am very sorry about that :(

Russell Donovan over 12 years ago
I also couldn't post my model through the contest page, so I have uploaded it and tagged it.
Joe Birner over 12 years ago
ALL are very cool concepts and ideas. I had no idea we would have such the turnout. The talent that participated completly surprised me.
Cemal Uslu over 12 years ago
This is september 12th in İstanbul.. Hope the results will be announced when i wake up :))
Shridharan over 12 years ago
When will be the results announced...............................................................................eagerly waiting fr it..!!
Robert Voogt over 12 years ago
Be patient my friends, I think that they underestimated the number of entries and need a little more time to pick the winners.
Alireza SKH over 12 years ago
wait wait wait wait ..............die die die die .................. no result no result no result
Shridharan over 12 years ago
Y t results r nt yet published....??? Any grabcad staffs pls answr fr tis.....
Buks over 12 years ago
Sept 13 ......... When can we expect the results to come out ?
Alfredo Gallozzi over 12 years ago
4th and 5th place???
Karco over 12 years ago
I agree with Aldolino:
You said that there would be 5 awards in total...
I thought understood another thing that I did not like much:
You, GrabCad, do selection only a few?
That is what happened with the "Saareyacths"? Because if so, I understand some things.
Thanks for reading and I hope answers.
A greeting.
PD: In any case, congratulations to the winners ))
Kir Ari over 12 years ago
Who do we congratulate for 4th and 5th???
Adam Pohl (POHL3D) over 12 years ago
Wait where are 1-3 announced?
Danny Tasmakis over 12 years ago
Adam, there is a 'Results' tab at the top of the page.
Adrian Molodet almost 12 years ago
that ramp can kill people :) someone could get impaled in it..
