There were significant sounds recorded on audio at the beginning of the Plasco collapse and they were analyzed and shown to have the pressure pulse form of explosive noise and not that of impact noise. There is a difference which you can see on pdf page 26 in the paper Fundamentals of Acoustics by Colin Hansen here
These pulses also seem to be too close together to have been from falling and impacting floors. The time between the seven pulses, measured over a 511 millisecond period, at the beginning of the collapse, ranges from 40 to 120 milliseconds, varying randomly, with no regular pattern of getting shorter as time went on.

Thermite doesn't make a loud explosion.
THE PLASCO BUILDING COLLAPSE IN TEHRAN
2.1 Explosions Before Collapse
Second, there appears to have been a series of larger explo- sions that started a few minutes before the collapse. This is indicated by at least two eyewitness accounts and by video evidence.
Four: characteristics rule out the possibility that these impulses were produced by a single BLEVE or other spontaneous explosion, or by collapsing
In summary, the data collected to date regarding the expulsions observed during the collapse and the occurrence of ex- plosions prior to collapse suggest that these expulsions were explosions and that explosives are the only viable explanation put forward thus far.
