It's up to you. It's a design competition, so I don't believe our judges will be looking specifically for every single detail that isn't self-explanatory. If there's a hole in the tubing that matches the hole in a gusset, they will know a bolt/rivet goes there. Rule of thumb - if it matters to how the design works, put one in IF it isn't already obvious.


Also, Chris, great looking design so far!
