The footings of certain structure were designed using 3000psi, this was before the soil report was available. When the soil report became available, it turned out that the actual soil bearing capacity was less than the assumed by the structural engineer, 1500 psi only.

Is the building already occupied? Is the footing piled or using pad footing? What you can look into is to underpin the existing structure by transferring the support or adding more support for the structure. As no detail is given for the stage of construction, it is hard to give an economical method of rectification.

I don't know an effective way of stabilizing the soil enough to allow the use of the original footing design. You do have several other options:
1. Dig down deeper to where you have the required bearing strength and extend the footing down to this level.
2. Change the footing design to compensate for the lower bearing surface (make footing bigger so loading is at the 1500 psi)
3. Change design to use piers

Have you ever heard of soilcrete? Try to research on this technology
