Here's how you insert it into your map:
 
Take the folder "Bleachers" out of the zip file, and put it in your shapes folder, then rename material.cs file and the main.material.json file from "insertmap" to whatever your map is named in the file work. 
 
One more small update eventually, will be adding more scaffolding to the Bleachers. 
 
Model built by me, I ask for credits if you decide to use them.
