1 Chronicles 28:19-21

19 “All this,” David said, “I have in writing as a result of the Lord’s hand on me, and He enabled me to understand all the details of the plan.”
20 David also said to Solomon his son, “Be strong and courageous, and do the work. Do not be afraid or discouraged, for the Lord God, my God, is with you. He will not fail you or forsake you until all the work for the service of the temple of the Lord is finished. 21 The divisions of the priests and Levites are ready for all the work on the temple of God, and every willing person skilled in any craft will help you in all the work. The officials and all the people will obey your every command.”
1 Chronicles 28:19-21

Although David was given the plans for the temple he was not permitted to build it. David wanted to build a temple as he felt it was wrong for him to live in a fine house of cedar while the Lord ‘s ark of the covenant resided in a tent. After David was established as King over all of Israel Hiram king of Tyre sent messengers to David, and cedar trees, also carpenters and masons who built David a house (2 Samuel 5:11). So David turned to the prophet Nathan [W]hen David lived in his house, David said to Nathan the prophet, “Behold, I dwell in a house of cedar, but the ark of the covenant of the Lord is under a tent.” And Nathan said to David, “Do all that is in your heart, for God is with you” (1 Chronicles 17:1-2).

However, it was not to be for the same night the word of God came to Nathan saying,

“Go and tell My servant David, ‘This is what the Lord says: You are not the one to build Me a house to dwell in. I have not dwelt in a house from the day I brought Israel up out of Egypt to this day. I have moved from one tent site to another, from one dwelling place to another. Wherever I have moved with all the Israelites, did I ever say to any of their leaders whom I commanded to shepherd My people, “Why have you not built me a house of cedar?”’
1 Chronicles 17:4-6

It is not until David has gathered much of the material for the temple that David tells Solomon why he cannot build the temple and it will be up to Solomon to build it.

7 “My son, I had it in my heart to build a house for the Name of the Lord my God. 8 But this word of the Lord came to me: ‘You have shed much blood and have fought many wars. You are not to build a house for My Name, because you have shed much blood on the earth in My sight. 9 But you will have a son who will be a man of peace and rest, and I will give him rest from all his enemies on every side. His name will be Solomon, and I will grant Israel peace and quiet during his reign. 10 He is the one who will build a house for My Name. He will be My son, and I will be his father. And I will establish the throne of his kingdom over Israel forever.’
1 Chronicles 22:7-10

Now we have real insight as to why David said with great confidence in our last verse of the day The divisions of the priests and Levites are ready for all the work on the temple of God, and every willing person skilled in any craft will help you in all the work. The officials and all the people will obey your every command. All of Solomon’s commands were indeed followed and the temple was built according to the plans given to David and handed down to Solomon.
