Real Areas Instead of Floor Plans

Holzbau Grieshaber GmbH, 25 employees — steep roofs, dormers, storey additions. Surveying until now: folding rule, roof ladder, courage.

1.41×

The 45° Factor

A 45-degree roof is more than 40% larger than its footprint — the “silent partner” in every floor-plan quote.

±2%

Quote Accuracy

Pitch-corrected roof areas straight from the geometry — instead of “we’ll see what it comes to.”

0

Scaffolding Reorders

Facade areas per side, following DIN 18451 logic — scaffolding fits the first time in the scenario year.

25 min

As-Built Survey

Top floor scanned with an iPhone instead of half a day on a ladder.

Studio
The roof knows its dimensions

Ridge, eave, verge — all edge lengths and billing units of the trade fall straight out of the roof geometry.

Scan
LiDAR instead of ladder

RoomPlan import turns the top floor into editable walls; collar beams measured without scaffolding — faster than the folding rule.

Field
Weather at your back

Storm damage by voice and photo, DWD data auto-attached: the June 14 hail became a data record, not an assertion.

Gewerkton — from our own media bank

“For years, the difference between floor area and roof area was our silent partner. Now the model calculates it.” — Owner, fictional Holzbau Grieshaber

Ridge, eave, verge, cos α: A roofing and timber construction company gets its billing quantities straight from the roof geometry — scaffolding included.

The Starting Point

Quotes based on floor area, billing based on debate: the true roof area of a 45-degree roof is more than 40 percent larger than its footprint — forget that in your quote and you’ll spend the summer working for the difference. And the scaffolding was regularly ordered too small.

Studio: The Roof Knows Its Dimensions

Pitch-corrected areas and all edge lengths fall straight out of the roof geometry: ridge, eave, verge — the billing units of the trade. The scaffolding areas for each facade side sit alongside, following DIN 18451 logic.

Scan Instead of Ladder

For a storey addition on an existing building, the foreman scans the top floor with an iPhone; the RoomPlan import turns it into editable walls. Measuring collar beams without scaffolding — the LiDAR was faster than the folding rule.

Field: Weather at Your Back

Storm damage documentation by voice and photo, DWD weather data automatically attached to the day: for the customer’s insurer, the hail on June 14 was no longer an assertion but a data record.

The Figures from the Scenario

– Roof area quote accuracy: ±2 % instead of “we’ll see what it comes to” (45° roof: factor 1.41!) – Scaffolding fits the first time: no more reorders in the scenario year – As-built survey of the top floor: 25 minutes of scanning instead of half a day on a ladder

“For years, the difference between floor area and roof area was our silent partner. Now the model calculates it.”

Fictional case study: company, people, and figures are invented and serve illustrative purposes. It is based on the target build-out of the Gewerkton platform (Field, Studio, Cloud, Archive, Operations). Gewerkton is a voice-first platform for construction documentation and defect management for global markets — with the deepest integration into German construction standards (GAEB, REB, XRechnung, DATEV), 27 content languages, and regional AI provider choice.
