Yes, I have dealt with many such cases back in the 70's and 80's. But in the more recent past and now currently there are many code and liability issues.
That's why I recommended the engineer. But, on the less expensive side, probably the best place to start would be YOUR County Building Officials. Go in and talk to them to see what is required in your area.
Even today, every jurisdiction is going to be slightly different. And it could be that in rural Kansas there are still things that get done with less expense than those things we have so far suggested.
BUT, I would be very careful and make sure that someone has gotten their ducks in a row. Even if the school is allowed to do some of this 'on their own' and not put it out to bid and have the drafting class to the plans and the students do this and that (yes, been there and done that) I/you should still want a certain amount of official oversight such as at least a review by an engineer. And I would think all jurisdictions would have a certain level of inspections that would need to be completed.
Bottom line, your OP mainly asked about books you could get. Sure, there are many out there. But much of that is above our paygrade. You need to find out all of your legal responsibilities first. Then start dealing with your code responsibilities. Then, if allowed in that location, work with them to come up with what they want.
Having said all that, remember this is from a guy that gets accused often on this forum of pushing for code adherence. My little company here in rural N. AZ has more certs, insur, licenses, and paperwork than most people even begin to understand. And I go to the city or county, depending on whose jurisdiction the job will be in, and find out if the customer/engineer/General Contractor has everything in order. It is not a 'SIMPLE' process. But we are dealing with public safety and those kids are either kids you know, kids of someone you know, or grandkids of someone you know. Plus, I wouldn't want to be known as the guy on the news who killed all those kids with below properly engineered standard work that didn't hold up.
Have a Great Day, Brent
