Matthew Henry's Concise Commentary

3:10-15 The apostle was a wise master-builder; but the grace of God made him such. Spiritual pride is abominable; it is using the greatest favours of God, to feed our own vanity, and make idols of ourselves. But let every man take heed; there may be bad building on a good foundation. Nothing must be laid upon it, but what the foundation will bear, and what is of a piece with it. Let us not dare to join a merely human or a carnal life with a Divine faith, the corruption of sin with the profession of Christianity. Christ is a firm, abiding, and immovable Rock of ages, every way able to bear all the weight that God himself or the sinner can lay upon him; neither is there salvation in any other. Leave out the doctrine of his atonement, and there is no foundation for our hopes. But of those who rest on this foundation, there are two sorts. Some hold nothing but the truth as it is in Jesus, and preach nothing else. Others build on the good foundation what will not abide the test, when the day of trail comes. We may be mistaken in ourselves and others; but there is a day coming that will show our actions in the true light, without covering or disguise. Those who spread true and pure religion in all its branches, and whose work will abide in the great day, shall receive a reward. And how great! how much exceeding their deserts! There are others, whose corrupt opinions and doctrines, or vain inventions and usages in the worship of God, shall be made known, disowned, and rejected, in that day. This is plainly meant of a figurative fire, not of a real one; for what real fire can consume religious rites or doctrines? And it is to try every man's works, those of Paul and Apollos, as well as others. Let us consider the tendency of our undertakings, compare them with God's word, and judge ourselves, that we be not judged of the Lord.

another commentary writes

Clarke's Commentary on the Bible

1 Cor 3:11-15 For no one can lay any foundation other than the one already laid, which is Jesus Christ. If any man builds on this foundation using gold, silver, costly stones, wood, hay or straw, his work will be shown for what it is, because the Day will bring it to light. It will be revealed with fire, and the fire will test the quality of each man’s work. If what he has built survives, he will receive his reward. If it is burned up, he will suffer loss; he himself will be saved, but only as one escaping through the flames.

Essentially this verse is talking about how we live our lives and what our reward will be in heaven. Our foundation is Jesus, it is Jesus who saves our lives and allows us to enter into heaven. What we do with our salvation, is what we are building on top of that foundation. When the day of judgement comes, what we have done will be "tested by fire" if our foundation is Jesus we will have our salvation, if what we laid upon that foundation is true/noble/worthy it will pass through the fire and will become our reward. But if it is burned up, we will only pass with out lives as if we barely escaped the fire (only because of the foundation)

I hope that makes sense.
