ABSTRACT
Globally temporary working platforms are an underrated element of almost every construction site. Geogrids have been installed in the temporary working platforms for decades now, as they offer contractors large cost, time and carbon savings compared to alternative solutions. The use of hexagonal, multiaxial stabilisation geogrids and square, biaxial geogrids is by far the most common method for the cost-effective solution. However, designing temporary working platforms using geogrids constitutes a challenge, as broadly available methods (e.g. BR470) present a conservative approach for incorporating geogrids in the designs that results in non-cost effective design. Moreover, geosynthetics manufacturers methods are validated only for specific manufacturers products (e.g. 45° load spread or T-value method). This paper discusses the importance of temporary working platforms design methods full scale validation and lists ideal site conditions for full scale validation tests. Also, it reviews recently undertaken site tests that aimed at testing temporary working platforms full bearing capacity and examining the design methods.
