Douglas9412,
Not sure it is true that the stand was to be demolished.
Points of interest in the Popplewell Inquiry Interim Report into the Bradford City Fire:
3.126
// The stand had been there for 75 years. By irony, it was the second to last game before the timber flooring would have been replaced by concrete. That work would have started on the following Monday. //

The inquiry states that modifications were to be made to the stand with wooden flooring to be replaced by concrete flooring. They wouldn't do that if it were to be demolished.
Whether it was worthless, it would be interesting to know what the insurance payout was, because that would prove if any financial gain resulted from the fire.
