Improvable Monument: Community Seesaw

Concept:
I am going to make a giant Seesaw and place it in front of the Flower Conservatory in Golden Gate Park in San Francisco. It will be made from non oxidizing metals so it does not rust or lose it’s coloring. It will be large enough for at least 10 people to fit on either side of the Seesaw in order for it to work. The reasoning for this is that I want something to bring the community together for no reason other than just pure recreation. This monument is for fun only. There will be only one handle on either side of the Seesaw, which will be located toward the center, meaning all the people on it will have to hold onto each other to make sure that the will not fall off.
There will be hands engraved in the body of the Seesaw, not only for decoration and design, but also not make the surface of the Seesaw less slippery. It will give the riders more of a grip when they are playing.
The reasoning for placing it in front of the Flower Conservatory in Golden Gate Park is because it is already a relaxing place where people go to enjoy a lovely day with their family and friends. And adding a sculpture that is purely based on the concept of fun, I believe will fit in perfectly with this environment. Also, there is a lot of space in front of the Conservatory that people picnic on, so there will be space for the monument and still space for people to enjoy their picnic on the grass.
Materials:
Stainless Steel Spring: (Spring for the Seesaw to move) Is a low allow, medium carbon steel or high carbon steel with a very high yield of strength. This allows objects made of spring steel to return to their original shape despite significant bending or twisting.
Platinum: (Body of the Seesaw and on either side of the spring and the handle bar) As a pure metal, platinum is silvery-while in appearance. It does not oxidize at any temperature. Platinum’s resistance to wear and tarnish is will suited for making fine jewelry. The meal has an excellent resistance to high temperatures and had stable electrical properties. Platinum is an extremely rare metal. Price of platinum, like other industrial commodities, is more volatile than that of gold. This year the estimated price will soar to 675 dollars per ounce.
Price:
Spring Steel:
Thickness: 1.0 inches’ (polished)
100 Ton: $600 (200,000 pounds)
1 Ton= 2,000 lbs
I will be only using 300lbs of steel, but unfortunately you have to buy at least 1 Ton. So there will be a lot left over to resell.
Platinum:
$675 per ounce
200lbs= 3,200oz
$675 x 3,200 = $2,160,000
Carving:
Would be no less than $3,000 due to the size and detail.
Welding:
Charged for total labor and material cost per pound of deposited welded metal. Cost would approximately be around $1,000.
Total Price:
Approximate cost of sculpture: $2,164,600 (not including moving and transportation)
Dimensions:
Platinum Body:
25 feet long
1.5 feet wide
2 inches thick
Stainless Steel Spring:
1 inch thick- multiple coils so it is sturdy enough to hold the Seesaw with weight of people.

Final Project: The Community See-Saw

I decided that I am going to go with my See-Saw idea. I liked the fact that it is not only a big object in a public space, but that it is actually functional and useful. Also, I like the concept of it needing a bunch of people joining together in order for it to work. Bringing the community together for recreational purposes only. I believe that there are so many things out there with the purpose to teach or to bring awareness to, which is fine and great, I just think that there should be things out there that propose nothing but fun. There is no deep thinking involved, all you need are other people to join in on the fun.
This will be made out of some type of metal. I don't know the exact type yet, but something that will not rust or pose a safety hazard... for this piece will be of all ages. Also, I would like the material to be sustainable, I do not want anything that would be hazardous to the environment over time. I need to do more research on what type of material would be the best to use.
The See-Saw will be large enough to fit at least 10 people on either side. There will only be one handle, which will be the seat closet to the middle of the See-Saw. I thought of this so that people would have to hug each other to make sure that they don't fall off, not them relying on a handle. I want this piece to bring unity within the community.
It will be placed in the Golden Gate Park of San Francisco. I am thinking right in front of the Conservatory of Flowers. There is a large grassy space there where people of all ages hang out. Also, there is already a friendly vibe there because of all the beautiful flowers and just the fact that it is not by busy road so it is quieter than other areas of the park.
The design is not going to be very creative. It will look like a normal See-Saw... just a lot larger. However, there will be etchings within the metal of the See-Saw. I am thinking hand prints of all sizes. I have not totally decided if I want it to be all one color (like silver or something) or if I want the hand prints to be different colors.
I still obviously have a lot more figuring out to do, but I have my basic idea and I am really happy with it.
My next step will be to figure out what the best material would be to use, how much this would cost, the dimensions and that color or colors the See-Saw will be. Then I will be creating it on Photoshop and virtually placing it in front of the Conservatory of Flowers at Golden Gate Park.
