I am planning to build semi-circular concrete steps. 2 steps, each step will have 4.5in rise; top step has 2ft radius, the bottom - 37 in. I have 2 questions.
1. I searched internet and books for an example how to build the forms for semi-circular steps. The only example I could find is here: http://www.packagepavement.com/building_steps_qk.html
. I can't understand how the form for the top step is held in place. Actually, 2x8 of the bottom step where it touches the house in the bottom right corner of the image also does not have a stake or any other visible means of holding it in place.
Also, with 2x8 of the top step going all the way down to the bottom step, how do you screed the bottom step? Am I missing something or this is just an ad photo and is not a real thing? Can someone post/describe any other examples for the forms?
At the moment I am planning to leave the stakes of the bottom step form as high as the height of the top step, brace the stakes and then attach 1X4 to the stakes and the top step form.
2. Steps will be covered with mortared brick. As I said, the final rise of each step is 4.5 in. Minus brick's height 2 3/8in and minus 1/2in of mortar. That gives the height of the top concrete step of 1 5/8 in. Besides additional headache for building the form for such a low top step, does anyone see any potential problems with this?
