Hacom Hoa Binh 5 Bac Lieu Province Vietnam Working Platform
Hacom Holdings faced rising material costs and tight schedules while rebuilding maintenance platforms for Bac Lieu Province’s wind turbines. By deploying Tensar InterAx geogrids, engineers reduced platform thickness by 25%, saving 15% per m² in material costs and lowering carbon emissions via minimised fill imports. On-site plate load testing confirmed structural integrity, proving the design’s efficiency for crawler crane operations. This optimisation highlights how advanced geosynthetics enable sustainable, cost-effective infrastructure in challenging environments.
Benefits
- 25% thinner platform construction with Tensar InterAx geogrids
- Material reduction equated to 15% per square meter in cost savings
- Reduced carbon emissions by minimising imported fill volume
The client needed to rebuild five temporary platforms for wind turbine maintenance using heavy crawler cranes. Given the previous success with Tensar’s mechanically stabilised platform, the client sought Tensar InterAx geogrids to reconstruct a more cost-effective solution, particularly due to increasing stone costs and tighter repair schedules in Southern Vietnam.
Tensar InterAx, Tensar’s best-performing geogrid was selected in the Tensar+ Working Platform module with the T-Value design approach. By adopting this method, Tensar’s design engineers were able to rationalise the original design where three layers of geogrid was proposed originally, to a more effective design which resulted in a thinner platform with only 2 layers of Tensar InterAx geogrid. The design achieved a 25% reduction in granular platform thickness. The performance of the platforms was then verified on-site by plate load testing.
