Case Study: Ringlock Scaffolding System Enables 39-Meter Safe Access for Historic Church Renovation in Europe

01. Technical Background

St. John's Church in Riga, Latvia — a centuries-old landmark — underwent a comprehensive renovation of its facades and spire windows. The project faced three unique challenges:
  • No existing architectural drawings — the church's original plans were lost
  • Restricted roof access — traditional scaffolding could not be erected without touching the delicate roof structure
  • High pedestrian traffic — located in the city center, construction had to minimize disruption to daily life
The contractor deployed Doka’s Ringlock scaffolding system, leveraging its modular flexibility to adapt to the complex geometry of the historic building.

02. System Specifications & Performance

Parameter
Specification / Result
System type
Ringlock modular scaffolding (rosette + wedge-lock)
Scaffold height
39 meters (tower + stair tower access)
Connections per node
Up to 8 (horizontal + diagonal + vertical)
Assembly tool
Hammer only (no bolts, no loose parts)
Surface finish
Hot-dip galvanized steel
Service life
8+ years
Digital design
DokaCAD laser scanning (replaced missing drawings)
Engineering advantages:
  • Reverse engineering via 3D laser scanning — building dimensions captured on-site and imported into DokaCAD to generate precise scaffolding layouts without original plans
  • 8-direction rosette connection — adapts to irregular church geometries, enabling flexible platform heights and angles
  • Integrated stair tower — the 39-meter tower included Ringlock stair systems, allowing workers to reach working levels safely without climbing vertical standards
  • Zero roof contact — the system was designed to avoid any load transfer to the delicate historic roof structure

03. Performance Results

Metric
Result
Scaffold height achieved
39 meters (with stair tower)
Building contact
Zero (no load on roof or delicate facade)
Worker safety
Fully enclosed platforms — met highest European safety standards
Pedestrian access
City center walkways remained open throughout construction
Client validation: The Ringlock system's modular flexibility, combined with DokaCAD digital planning, successfully solved the most challenging aspects of heritage renovation: missing drawings, confined space, and high-altitude safety.

04. The European Renovation Wave Context

Europe is undergoing a "Renovation Wave" — a major initiative aimed at achieving climate neutrality by 2050. Ringlock scaffolding systems have played a critical role in this movement:
Project
Application Highlight
Mühlkanal Bridge, Austria
Suspended Ringlock scaffold fully wrapped a 40-meter bridge span, protecting river from contamination during corrosion protection work
Horst Castle, Belgium
100+ tonnes of Ringlock scaffolding with custom 1.09m platform widths for enhanced safety
Warsaw Philharmonic HQ, Poland
Dual Ringlock system reinforcing 120-year-old facades
Sustainability value: Ringlock systems are demountable and reusable across multiple projects — significantly reducing the need for new material production and lowering embodied carbon.

05. Applications

Ringlock scaffolding systems are widely used for:
  • Heritage building facade and spire renovations
  • High-altitude access in confined urban spaces
  • Corrosion protection work on bridges and tunnels
  • Temporary support structures for complex geometric forms
