Bermondsey Dive Under
Tensar designed working platforms incorporating TriAx were key to the success of foundation works alongside a railway viaduct in south east London.
- £40,000 estimated saving based on reduced excavation and material costs
- 20 days cut from the construction programme
- 400mm reduction in working platform thickness
- Network Rail-compliant alternative design
Main contractor Skanska required a temporary working platform to support piling equipment capable of passing Network Rail’s rigorous approvals process and enabling construction of foundations for a major new rail junction in Bermondsey.
The working platform comprised layers of site-won granular fill, mechanically stabilised with TriAx® geogrids. The efficient load spread design, validated by Tensar’s 35 years’ experience and extensive full-scale performance testing, shortened the piling platform construction programme, reduced costs and lowered the project’s carbon footprint, compared with conventional working platforms.
