Tensar were approached to provide a Mechanically Stabilised Layer (MSL) for ground stabilisation, to construct a working platform for piling rig operation
Benefits
- £350,000 (48%) estimated reduction in construction cost
- 70 days (58%) estimated reduction in construction time
- 140,000kg CO2e (53%) estimated reduction in environmental cost
The challenge was to provide a cost effective engineered solution using recycled material that was generated from within the total site area of 44,000m2. The design proposal was also required to carry all construction traffic operating across the site
Following the guidance provided by the Building Research Establishment (BRE) on the use of alternative working platform design methods, Tensar adopted the “T-Value” approach to rationalise the platform thickness, accommodating the request to use recycled material.
The resulting mechanically stabilised platform was constructed using a Class 6N material, placed to the specific depth required, incorporating Tensar InterAx geogrid placed on the made ground formation, which had a Cu value of 50 KPa.
