Readiness check

Is your layout built on good control or guesswork?

Construction layout is only as good as the control it comes from. Lay out from a disturbed point or the wrong datum and the whole building is in the wrong place. Answer for how layout actually runs on your site. The score stays on your device; enter an email only if you want the layout checklist sent over.

1. Is there an established, surveyed control network (benchmarks and control points)?Yes, a surveyed control networkA few points, not formally surveyedWe lay out from whatever is handy

2. Are the control points protected and checked before use (not disturbed)?Yes, protected and verified each timeAssumed goodPoints get bumped and reused anyway

3. Are you laying out on the correct coordinate system and datum (site vs building grid)?Yes, the right system confirmedUsually, not always checkedDatum confusion has bitten us

4. Is the tool matched to the work (total station for tight points, GPS for site and earthwork)?Yes, tool matched to the precision neededOne tool for everythingTape and guesswork

5. Do you lay out to the tolerance the work needs (anchor bolts tight, walls looser)?Yes, tolerance matched to the elementOne tolerance for allWe do not track tolerance

6. Do you pull layout points from the coordinated model where one exists?Yes, model points to the total stationWe transcribe from 2DNo model link

7. Is the layout independently verified before the pour or the install?Yes, a check before concrete or steelSometimesWe pour and hope

8. Do you capture an as-built to confirm what was actually built?Yes, as-built shot and recordedOccasionallyNo as-built
