About this file
This federal contract opportunity notice provides details for a potential project to provide bank protection and stabilization along the American River in Sacramento, California. The U.S. Army Corps of Engineers, Sacramento District, anticipates requirements for roughly 7,800 feet of stream bank protection and stabilization at two sites, including clearing vegetation, placing soil and rock revetment, excavating the riverbank, installing rock tiebacks, backfilling, and planting. Work will be performed over two construction seasons and will require import and placement of various rock gradations totaling approximately 106,000 tons, approximately 12,000 tons of bedding material, approximately 365,000 cubic yards of soil excavation and off-haul, approximately 295 trees, and approximately 4,700 plant cuttings. The estimated magnitude of construction is between $25 million and $100 million. Interested vendors should monitor the beta.SAM.gov website. This notice provides anticipated requirements but the project, solicitation, and contract are subject to change or cancellation.

Stop HSA drilling @ 33.5 ft due to difficult drilling/refusal.
Drilling noisy.
Change back to mud rotary @ 33.5 ft
Very difficult drilling took 1.5 hours to advance 6 inches.
Using a tricone bit
Very difficult drilling took 4 hours to advance 2 feet.
All slough and sample fell out. No recovery.
Lithology assumed from cuttings
Drilling took 40 minutes to advance 2 feet From 38.0 to 39.4 ft may be slough?
Sample S4A used Cal-mod sampler Sample S4B used SPT sampler and had 2" lense of medium grained sand with a trace of gravel at the bottom Hole caved in. Casing driven to 40 ft Used sand catcher in Cal-mod sampler, but no recovery Drove SPT after no recovery with Cal-mod sampler.
Most likely slough Stopped drilling at 12:30 due to refusal.
