Ridgeline, phase two. Four houses off the same 2,450 square foot two-story plan, two of them mirrored, all four framed by the same crew of seven inside eleven weeks. You bid 640 hours a house for the frame. Sticks, sheathing, trusses, roof deck, interior partitions, backing and blocking, ready for the mechanicals.
Total bid: 2,560 hours. Total actual: 2,774. You were 214 hours over across four houses.
At a $61 loaded rate that is $13,054, and when the bookkeeper showed you the framing labor number for phase two, you did the same arithmetic every framer does. Divide by four. Fifty-three hours a house. Eight percent. On a four-house run in a wet spring that is close enough, and the crew is good, and you moved on.
The average was hiding one house
Here is what the four lots actually did:
- Lot 4 — 612 hours
- Lot 5 — 658 hours
- Lot 6 — 631 hours
- Lot 9 — 873 hours
Three of those four houses came in within eighteen hours of the bid. That is a crew that knows the plan and a bid that is priced correctly. Lot 4 beat it. Lot 5 and Lot 6 were normal.
Lot 9 was 233 hours over on its own. $14,213 of labor on one house, and it made all four houses look eight percent sloppy when three of them were exactly right.
That distinction is the whole thing. Eight percent across a run is a conversation about tightening up. Two hundred and thirty-three hours on one lot is a conversation about a specific decision somebody made on a specific Tuesday, and it has an answer.
An average is what you compute when you cannot see the individual numbers. It is not information. It is the absence of information, expressed as a number.
Where Lot 9 actually went
The answer took twenty minutes to find once anybody looked at the lot by itself.
Lot 9 was the only one of the four with the three-car side-load garage option, which meant a different roof geometry and a raised-heel truss package that shipped from a different plant. That package came in eleven days late. The crew had already stripped the walls and was standing there on a Thursday with no trusses.
So they broke down and moved to Lot 5, and came back eleven days later. That remobilization cost roughly 40 hours in setup, staging, walking material back, and re-establishing layout that had been rained on twice.
Then the bonus room option changed the second-floor bearing wall. The revision landed after the deck was on. That was 96 hours of rework by two men over six days, and there was no change order for it because at the time it looked like a small drawing revision.
The rest — call it 97 hours — was the side-load garage itself being genuinely harder to frame than the front-load the bid was priced on. Longer headers, a different roof tie-in, and cutting instead of setting.
Three causes, all of them real, none of them the crew's fault, and all three still happening on phase three because nobody had a number to point at.
Why parallel lots hide this so well
Framers run lots in parallel. That is the business. Two houses standing walls, one being sheathed, one waiting on trusses, and a crew of seven that splits three and four some mornings and re-splits after lunch when the delivery shows up.
Now try to allocate that week's hours to four lots. The foreman writes seven names and a total on a timesheet Friday afternoon, and the whole week goes to Ridgeline. It has to — nobody is going to reconstruct which man was on which slab on Wednesday morning. So the job costs by subdivision, and every lot inside it becomes an average by default.
The fix is not more paperwork. It is putting the lot on the clock-in rather than on a Friday reconstruction. A six-digit code, no app to download, the man picks the lot he is standing on, and GPS on the row confirms it. When he moves to Lot 5 after lunch, he clocks out of one and into the other, which takes about eight seconds. Hours land on the right lot the moment they happen, and Friday becomes a review instead of a reconstruction.
Two weeks of that and you have something no timesheet total will ever give you: four columns you can put next to each other.
You would have caught it on day nine
This is the part that pays for the eight seconds.
Lot 9 did not go 233 hours over in a single event. It went over in three stretches spread across five weeks. With hours landing per lot, the remobilization would have been visible the week it happened — 40 hours logged to a lot with no measurable progress on it and a truss delivery still open on the schedule.
That is not a report anybody has to run. It is a thing you notice on a Monday when Lot 9 has 128 hours on it and Lot 6 has 71, and both are supposed to be at the same stage.
Catch it on day nine and you make different decisions. You call the truss plant on day two of the delay instead of day eleven. You do not break the crew down until you have a confirmed ship date. You put the bearing wall revision in front of the builder as a change order while the framing is still open and the cost is still obvious, instead of eating 96 hours because six weeks later it is awkward to bring up.
Even if you change nothing at all, you finish phase two knowing that 640 hours is the right bid for the front-load plan and the wrong bid for the side-load. That single fact is worth more than the $13,054, because the next phase is twelve lots and four of them have the garage option.
What per-lot hours turn into
Once the hours are on the lot, three other things become possible without any extra effort.
- Draw and progress billing stop being an argument. Lot 6 at 84 percent framed with 631 hours logged and the sheathing photographed is a document. Lot 6 at 84 percent because it looked about right on the walk is a claim. Builders paying on percent complete notice the difference.
- Remobilizations get priced. Every framer knows a broken-down crew costs money. Almost none of them can say what it cost last time. Forty hours and $2,440 is a number you can put in a delay clause.
- Your bid gets better one plan at a time. Not a general feeling that you are underbidding. A specific figure: the side-load option is worth 97 additional hours, so it is worth $5,917 in labor before anybody talks about markup.
Start with the run you are on now
You do not need to rebuild your estimating to do this. You need the lot on the clock-in and four columns you can look at on a Monday.
On your current run, write down the hours logged to each lot this week and the stage each lot is at. If the numbers track each other within ten percent, you are fine and the crew is doing what you think it is doing. If one lot is sitting forty percent higher than the others, go stand on it Tuesday morning and find out why, because in five weeks it will be a $13,000 average and nobody will remember the Thursday the trusses did not show.
