The "owner" of the school almost certainly has a relationship with an architect and/or engineer who handles technical matters like this. They may have the reports or other documents. It might be difficult getting access since your inquiry might be perceived as a possible legal quagmire. If approached professionally, you might be successful. In my experience in other jurisdictions, before many architectural or engineering projects can be started, an asbestos survey is required. That survey would entail collecting and testing samples of all suspected asbestos containing materials (ACM) which would be disturbed in the course of the work. If ACM are identified, an abatement plan must be developed and completed before the main work can get underway. One important point is this: the mere existence of ACM is not a real problem. ACM becomes a problem only when it is disturbed. If you had a pinch of any given material, you could find a laboratory which could examine your sample and determine if it contains asbestos, etc. Given the technical nature of your concern, coupled with the legal implications of real or imagined issues, you may want to step carefully going forward. Good luck.
