[§06.01] Geotechnical Borehole Soil Testing & SBC 303 Mandates
Geotechnical soil investigation is the foundational milestone for structural engineering compliance under SBC 303. Borehole samples uncover soil stratigraphy and groundwater tables across Riyadh rock formations.
[§06.02] Standard Penetration Tests (SPT) & Shear Strength Capacity
Boreholes drilled to depths of 10-30 meters extract undisturbed soil cores to conduct shear strength, swelling potential, and allowable bearing capacity stress calculations.
[§06.03] Foundation Type Evaluation: Spread Footings vs Raft Slabs
Based on certified geotechnical reports, structural engineers select optimum foundation types (isolated footings vs reinforced raft slabs or deep friction piles) to prevent differential settlement failures.
