Look at BRepBuilderAPI_Transform. You can create a scaling transform (gp_Trsf) with a scale factor and a point about which the scaling should occur.

take care, BRepBuilderAPI_Transform only works fine with scale when the scale factor is the same on all axis ( scalex = scaley = scalez )
if you have a deforming transformation, use BRepBuilderAPI_GTransform instead.
