SPENT POT LINING (SPL) STORAGE BUILDING - EMAL

The proposed warehouse building (175m x 45m), is a combined RCC-Steel structure aimed at storing the SPL materials. The foundation soil had bearing capacity and settlement issues due to the presence of a 2m thick loose soil deposits characterized by a very low SPT N-value (<4). The calculated settlement was 70mm, the acceptable value being 50mm. For this reason, the soil consultant recommended ground improvement with stone columns for the entire footprint area of the building. However the recommended solution was not feasible for the main contractor (M/s. Amana) due to financial & construction time reasons. In the tender, the main contractor budgeted with ‘slab on grade’ and the periphery footings on piles. consideration of stone columns for the floor location exceeds the budget and construction time (8 months in total).

Maccaferri was invited by the client & consultant to give an alternative solution of ground improvement. Upon review of the available geotechnical reports, an analytical ground profile was created by our geotechnical engineers. Various options of ground stabilization were checked by our technical team and finally a ground stabilization by high strength geogrids (PARALINK®300) was Maccaferri’s recommendation. Maccferri saved cost and time and energy on the project.
