Project Overview: As part of the Sobha Hartland development, Hira Walraven implemented a modular MEP support solution designed for corridor and riser installations. The system utilized prefabricated frames assembled off-site using slotted channels and connectors, enabling a streamlined and standardized installation. This method significantly reduced on-site work, improved safety, and increased efficiency.
Performance Improvements: Compared to the traditional installation method, the modular system delivered clear advantages. Installation was completed in one-third the time, manpower was reduced by 40%, and the number of fixing points dropped by 70%. Additionally, material wastage fell from 20% to just 5%, supporting more sustainable construction practices.
| Metric | Traditional System | Modular System | Improvement |
| Installation Time | Baseline | 3x faster | 66% time saved |
| Labor Usage | 1 | 0.6 | 40% labor reduction |
| Fixing Points | 1 | 0.3 | 70% fewer points |
| Material Wastage | 0.2 | 0.05 | 75% waste reduction |
Environmental and Efficiency Impact: By shifting labor off-site and reducing installation duration, the project achieved measurable sustainability gains. Approximately 1,200 man-hours were saved, translating into a reduction of around 1.4 tons of CO₂ emissions based on typical site activity benchmarks. Furthermore, waste was significantly minimized thanks to factorycontrolled precision cutting, eliminating unnecessary offcuts and errors.
System Advantages: The modular approach enabled faster and more reliable execution. Supports were delivered ready-to-install, eliminating on-site cutting. Layout and alignment were executed using standardized templates, ensuring consistency across all levels. Reduced drilling minimized disruption and improved worker safety, while Revit-based planning ensured coordinated routing of all services without conflict.
Each corridor, which would typically take up to a month using traditional methods, was completed in just one week using the modular system. This allowed for faster project turnover and reduced overall installation costs. The reduction in fixing points also meant less drilling into structural elements, preserving slab integrity.
Conclusion: The modular support system at Sobha Hartland was a clear success. It enabled a faster, cleaner, and more efficient construction process while contributing to lower emissions and material waste. The project demonstrated how prefabricated MEP supports can enhance quality, safety, and sustainability—all while saving time and resources on-site.
