Keller's engineering excellence and wide portfolio helped provide a mix of ground engineering techniques to suit different soil conditions and structural performance requirements. The selection of optimal foundation solution reduced the cost for the client and enabled early completion of the project.
Deepak Phenolics LTD (DPL) was constructing a phenol processing plant at Dahej, Gujar. Keller was commissioned by DPL to design and construct ground improvement works for the mounded storage vessels and storage tanks, and heavy foundation works to support other heavy plant structures.
The main challenges with the project were to meet technical specifications in silty and clayey subsoil strata and effectively utilise resources whilst working in collaboration with other contractors.
Keller provided an alternative to client’s proposal of a complete piling solution that combined vibro stone columns to support the mounded storage vessels and storage tanks and bored piles for the chimney, boiler and other processing structures. To keep post construction settlement (total and differential) within tolerable limits, the treatment area of the mounds was preloaded. This optimised foundation solution saved significant cost and time. For the convenience of the client, Keller also delivered foundation civil works.
