Engineering Standards & Calculation Methodology
Our calculation engine is built on deterministic engineering rules according to Eurocode 3, DIN 4108, and Passivhaus Institut PHPP benchmarks.
Cold-formed S350GD structural profiles. 38 to 49 kg/m² depending on storeys, with 0 mm structural settlement.
Thermal-bridge-free envelope, U < 0.15 W/m²K rockwool exterior wrap, airtightness n50 ≤ 0.6 ACH.
Truck counts calculated via real physical constraints: CFS steel weight, rockwool volume, and dedicated glazing A-frame stillages. Duty-free ATR & EUR.1.
Reduces operational space conditioning demand from 120 to 15 kWh/m²a. Up to 85% energy savings, paying back shell premiums in 6-8 years.

Frequently Asked Questions
Essential answers regarding steel construction, energy targets and project delivery.
P1 includes the precision manufactured structural steel frame and shop drawings. P2 adds external structural board sheathing, cavity insulation between studs, and moisture-control membranes.
P3 provides a fully weather-tight exterior envelope, including external continuous insulation, exterior finish infrastructure, roof waterproofing, and high-performance exterior windows and entrance door.
No. In all packages, excavation, ground engineering, and concrete foundations are local responsibilities managed by the client or local contractor.
Yes. While the package matrix sets clear baseline responsibilities, specific scopes (such as supply-only vs supply + erection supervision) are confirmed in the quotation.
MEP engineering and installations can be coordinated either through SerVilla project kits or through your local certified trade partners depending on the contract agreement.
