This screen does not price a bid and produces no bid total. The estimating system is not being replaced.
It supplies rates to whatever does the pricing, exported in a form that tool can consume.
Rock anchor drilling — m/shift
n = 34 shifts across 6 projects · p10 18 · median 31 · p90 44
▁▃▆█▆▃▁
| Condition | n | Net median | Interruption profile |
|---|---|---|---|
| Open ground | 19 | 38 | 6% of shift time lost |
| Constrained access | 9 | 26 | 14% — traffic control windows |
| Adjacent live rail | 6 | 17 | 41% of shift time lost to train passages |
A rate from a job interrupted by train passages is never silently compared to one from open ground. That is the whole point of recording interruptions as data.
Slope mesh — m²/crew-day
n = 12 · rope access median 210 · manlift median 340
Shotcrete — m³/shift
n = 8 · wet process median 22
⚠ No rate recorded below 5 °C ambient.
No rate recorded: soil nailing · drain hole drilling · grout injection.
Stated rather than substituted with a default.
Exported with sample sizes and interruption profiles attached. Format configurable to whatever estimating tool is in use — which is an open question.
