SITE INSPECTION
Following review of the design parameters, regular site inspections
were conducted to supervise the construction of the embankments and
to verify that the various design parameters were being met. The
following is a summary of the site inspections:
10/3/80 Observe construction methods; Inspect fill material
and progress of structures
10/4/80 Take samples of fill material from pit; Take samples
of fill material from embankments A, B, C, and D for
density and moisture determination
10/8/80 Check dimensions of principle spillway Embankment C;
Check progress of Embankments A, B and D; Take
samples for moisture and density tests of Embankment D
10/14/80 Inspect Embankment C, B, A, D and E; Take samples for
density and moisture determination at Embankment E
10/20/80 Inspect Embankments A, B, C, D and E; Check construction
methods and constructed dimensions; Take samples from
Embankment E for moisture and density determinations
10/27/80 Check dimensions of Embankments A, B, C, D and E;
Review required changes with George Patterson
10/31/80 Check dimensions of Embankments A, B, C, D and E
and progress of construction
11/21/80 Check final dimensions of Embankments A, B, C, D
and E prior to placement of rip rap material; Inspect
rip rap material at Sheep Mountain and Willow Creek
sites
2/27/81 Check final rip rap elevation and placement of rip
rap material for Embankments A, B, C, D and E
4/25/81 Check final rip rap placement of Embankments A, B,
C, D and E. Final inspection
Sample Testing and Analysis
Samples collected during the site inspections were analyzed to determine
the moisture content of the fill material and density of the fill
5 A ~ ~ lNC.
