Thermite may be used for repair by the welding in-place of thick steel sections such as locomotive axle-frames where the repair can take place without removing the part from its installed location.
Your telling me that Thermite is an explosion that was used to bring down buildings, and wikipedia is telling me it's not an explosive. Wikipedia is also telling me it's used in welding. The caption I grabbed says "thick steel sections" - as one would imagine would be used in a skyscraper.
Of course thermite is going to be present. The entire skyscraper was built using it.

Thermite can be used as a cutting agent, if Thermite was explosive this would be counter-productive during a controlled demolition as it would also blow the cutting agent away from the steel it was meant to cut. This is why Thermite is used in conjunction with with explosives during controlled demolitions; the Thermite cuts the steel then the explosives move the cut pieces away from the support structure
