Pre-permit build update. Nothing's in the ground yet, but this one's worth sharing. Before final opening sizes go to the steel side, I checked our working window and door list against the signed and sealed drawings, line by line. Here's what I found: - All 7 window sizes matched. Good. - The counts didn't. One window type showed 21 on the list. The drawings show 7. - The drawings call for 63 doors. The list had 8. The overhead doors, the fire-rated doors between the houses and the shop, and every interior door were missing. I also locked in door heights this week. The two front entries are 8'0". Every other door, inside and out, is 6'8". Why this matters on a steel build: the building's structural drawings frame your openings. The rough opening depends on the exact door or window unit you pick, and that changes by manufacturer. Miss an opening or send the wrong size, and you end up fixing it in steel instead of on paper. The order I'm following: 1. Pick the actual units. 2. Get the real rough openings from the manufacturer. 3. Reconcile them against the sealed set. 4. Then send sizes to the steel supplier. Your turn: did you check your window and door schedule against your drawings before you ordered? What did you catch, or what did you wish you'd caught? (Every build is different. Check your own openings with your engineer and steel supplier.)
