This document consists of four technical charts displaying grain size distribution curves for soil or clay samples under covered consolidation conditions. Each page presents a graph with the y-axis representing grain size in phi (φ) units and the x-axis showing percentage finer by weight (0-100%). The charts include detailed grid overlays and curved lines indicating the relationship between grain size and consolidation characteristics for different soil samples.

Each chart contains a legend box in the upper right identifying the project number (ranging from P-3271-2 through P-3271M-1), course classification (Fine, Medium Sand, or Silt or Clay), sample identification numbers, borehole locations, and case numbers. The curves demonstrate typical soil grain distribution patterns, with steeper slopes in some regions indicating more uniform grain sizes and gentler slopes indicating broader size distributions. These technical charts appear to be part of a geotechnical investigation or soil analysis report used to characterize subsurface materials for construction or engineering purposes. The data presented would typically inform foundation design, excavation planning, or other site-specific engineering decisions.
