Stop losing tender margins to manual takeoff delays.
Barrow reads your drawings, calculates exact quantities, and prices every item against live Nigerian depot rates. The whole thing takes minutes.
Why construction leaders replace spreadsheets with Barrow.
Manual measurement and stale rate sheets can cost contractors up to 14% in budget overruns before site work even starts.
| Category | Traditional | Barrow |
|---|---|---|
| Turnaround | 10–14 days per tender — senior QS engineers tracing scale rulers across printed floor plans. | 4 minutes. Upload drawings, get itemised quantities with wall areas, slab volumes, and reinforcement weights. |
| Pricing | Calling dealers one by one across Alaba, Dei-Dei, and Odunade with no way to compare prices. | Live depot rates pulled from across Nigeria. You see what materials cost right now, not last month. |
| Accuracy | Broken cell links, missed deductions, and rounding errors that have cost firms tender underbids. | All quantities calculated by formula. Click any figure to inspect the exact drawing coordinates and maths behind it. |
| Rate freshness | Bids on 4-week-old quotes get crushed by mid-project currency devaluations and haulage hikes. | When factory gate prices move, reprice your entire BEME in one click before submitting. |

From drawing upload to costed BEME in three steps.
Built for how Nigerian construction actually works, not adapted from a generic tool.

02
AI Takeoff, No Guesswork
The AI pulls dimensions and schedule callouts directly from your drawings. All quantities are calculated by formula, so there are no invented or estimated numbers in your output.
