Engineering Case Study

Overcoming Site & Structural Constraints

The Engineering & Logistical Challenge

Strict Bavarian snow load regulations (Schneelastzone 3, sk = 3.5 kN/m²) and stringent German building authority scrutiny (Prüfstatiker verification) required rigorous structural verification without allowing bulky heavy columns.

The SerVilla Pre-Engineered Steel Solution

SerVilla engineered cold-formed double C-studs and multi-ply steel roof trusses in Vertex BD with finite-element node verification. The complete prüffähige statische Berechnung was approved by the German Prüfstatiker without revisions on first submission.

International Freight & Customs Route
Direct factory dispatch from Gebze in a standard European Planen-LKW mega-trailer. Border clearance at Kapıkule under A.TR certificate ensured 0% customs duty. The cargo arrived in Garmisch-Partenkirchen within 5 days with zero transshipment damage.

Milestones & Schedule

Step-by-Step Project Execution Log

From initial 3D BIM engineering in Istanbul to jobsite handover in Garmisch.

Week 1–2 1

Prüffähige Statik & Thermal Bridge Analysis

3D FEA structural analysis strictly formatted to DIN EN 1993-1-3 and DIN EN 1991. Cold bridge elimination analysis for German GEG 2024 compliance and approval by local Prüfstatiker.

Week 3 2

CNC Precision Roll-Forming & Factory Bundling

Heavy gauge S350GD structural profiles manufactured on CNC roll-formers with 0.5 mm tolerance. High alpine heavy trusses bundled and labeled for sequential unloading.

Week 4 3

Direct Mega-Trailer Transit to Bavaria

Dispatched under A.TR movement certificate (0% duty). 5-day direct road transit across Austria into Upper Bavaria directly to the building plot.

Week 5–6 4

Structural Frame Assembly & Quality Sign-Off

Erection completed in 11 days by local Zimmerer carpentry team under SerVilla on-site engineering supervision, ready for exterior wood-fiber WDVS.

Clear Responsibility Boundary

Scope Division on the Garmisch Project

Transparent delineation between factory-engineered elements and local on-site trade coordination.

Manufactured & Supplied by SerVilla

  • Complete S350GD+Z275 framing kit with heavy alpine roof trusses
  • Prüffähige statische Berechnung nach DIN EN 1993 & Fundamentlastenpläne
  • Specialized high-load hold-downs (Simpson Strong-Tie HTT/HDU) and anchor schedules
  • Cavity rockwool insulation and airtight vapor barrier membranes
  • Bilingual SerVilla field engineer for assembly oversight and Prüfstatiker handover

Executed by Client & Local Contractors

  • Baugenehmigung application through local German architect (Entwurfsverfasser)
  • Reinforced concrete foundation slab and frost apron (Frostschürze)
  • External thermal insulation composite system (WDVS) and larch cladding
  • Triple-glazed Passive House windows and geothermal heat pump system

As an architect in Bavaria, I was skeptical about importing light steel from Turkey. But SerVilla's statics package was more complete than what we usually get locally, and the dimensional precision was within 1 millimeter.

Case Study FAQs

Technical Questions About this Project

Frequently asked engineering, customs, and assembly questions regarding the Garmisch delivery.

Sì. La relazione di calcolo è stata redatta secondo la DIN EN 1993-1-3 con allegati nazionali tedeschi ed è stata approvata al primo tentativo dal Prüfstatiker.

SerVilla ha calcolato doppi profili a C e capriate reticolari con ancoraggi Simpson Strong-Tie ad alta portata, resistendo a 3,5 kN/m² senza pilastri ingombranti.

Combinando 140 mm di lana minerale nell'intercapedine con 100 mm di cappotto esterno in fibra di legno, azzerando i ponti termici e raggiungendo un valore U di 0,12 W/m²K.
