I Corinthians 3:11 For other foundation can no man lay than that is laid, which is Jesus Christ.
 12 Now if any man build upon this foundation gold, silver, precious stones, wood, hay, stubble;
 13 Every man’s work shall be made manifest: for the day shall declare it, because it shall be revealed by fire; and the fire shall try every man’s work of what sort it is.
 14 If any man’s work abide which he hath built thereupon, he shall receive a reward.
 15 If any man’s work shall be burned, he shall suffer loss: but he himself shall be saved; yet so as by fire.

Romans 14:10 But why dost thou judge thy brother? or why dost thou set at nought thy brother? for we shall all stand before the judgment seat of Christ.

II Corinthians 5:10 For we must all appear before the judgment seat of Christ; that every one may receive the things done in his body, according to that he hath done, whether it be good or bad.

Here is my answer:

Revelation 20:11-13

11 And I saw a great white throne, and him that sat on it, from whose face the earth and the heaven fled away; and there was found no place for them.

12 And I saw the dead, small and great, stand before God; and the books were opened: and another book was opened, which is the book of life: and the dead were judged out of those things which were written in the books, according to their works.

13 And the sea gave up the dead which were in it; and death and hell delivered up the dead which were in them: and they were judged every man according to their works.

The Judgement Seat of Christ as seen and termed by Paul, the White Throne Judgement as seen and termed by John, and the Sheep and the  Goat Judgement as revealed and termed by Jesus Christ happened all at the same time and at the same place.
