This paper presents a combined geotechnical and geophysical investigation conducted at Warehouse-2 of Horizon Industrial Parks Pvt. Ltd., aimed at inspecting potential settlement issues. The study utilized Multi-channel Analysis of Surface Waves (MASW) in conjunction with the Standard Penetration Test (SPT) to obtain a multi-dimensional understanding of the subsurface soil profile. Findings indicated that the soil beneath the existing reinforced concrete slab was very loose, comprising an SPT ‘N’ value of less than 10 and shear wave velocity (Vs) of less than 180 m/sec, and construction was carried out without proper compaction. Recommendations were made to excavate and compact the soil layers and implement ground improvement, thus reducing the risk of settlements arising from the anticipated loads. The integration of geotechnical as well as geophysical methods significantly decreased uncertainties and enhanced the efficiency of the site investigation. Moreover, this integrated approach not only aids in identifying vulnerabilities but also provides valuable insights for reinforcing the warehouse structure effectively and economically, ensuring compliance with serviceability standards.
