Amendment 0004_1988_74_gsds.pdf

This document contains five pages of technical specification charts titled "Percent Coarse by Weight," each displaying grain size distribution curves for what appears to be aggregate or similar granular materials. Each chart presents a grid with percent finer by weight on the horizontal axis (ranging from 0 to approximately 100 percent) and percent coarse by weight on the vertical axis. The charts display distribution curves with accompanying data boxes that reference project information including dates (ranging from EL8/2-55/10 through EL8/6/22-23), project names (ALFALFA OCEAN SEISMIC, AREA SEA BRIGHT, CORING NO./RANGE 88-7/4), and sieve size designations (COARSE, FINE, MEDIUM, SAND). The curves on each page demonstrate different grain size distribution patterns, with some showing steeper slopes and others showing more gradual transitions. The multiple pages suggest different samples or testing conditions for comparative analysis. This appears to be a technical reference document used for quality control or specification compliance in aggregate material testing, but it does not contain contracting information, procurement requirements, pricing, dates of performance, or other elements typical of federal contract opportunities.
