a. General. - The geologic description, drawings, logs of subsurface explorations, water-level data, and test data in these specifications include information and records of geologic investigations for the work and are the final geologic data on which the design of the work is based. These data supersede any previous versions which may be available for examination by offerors. See Division 14.
Design features shown on the geologic drawings may not reflect more recent revisions which appear in these specifications.
Offerors are encouraged to obtain their own samples and perform tests on the soil and rock materials to evaluate properties which the offeror believes to be significant in arriving at a proper offer.
Geologic data and drawings obtained from the “Draft - Geologic Design Data Report for Block 9 - Stage 2, Laterals and Pumping Plant, Navajo Indian Irrigation Project, Farmington, New Mexico” were utilized in the preparation of these paragraphs. These documents may be examined at the Bureau of Reclamation, Four Corners Construction Office - Farmington, 2200 Bloomfield Highway, Farmington, New Mexico or at the Technical Service Center, 6th and Kipling, Building 67, Room 1068, Denver, Colorado. The contents of these reports may not reflect recent revisions which appear in these specifications.
The water-level data show the conditions at the particular time or times the information was obtained and may not indicate variations such as those caused by periods of drought or increased rainfall, seasonal fluctuations in rainfall, or applications of irrigation water.
b. Geologic Investigations. -
(1) Previous Investigations. - Investigations were conducted during 1980 by personnel of the Navajo Indian Irrigation Project Office, Farmington, New Mexico. Most of these investigations were located at proposed pumping plant sites which have since been eliminated. Only one of these explorations, drill hole PR-99, remains applicable to current Block 9, Stage 2 work and is located at the B0.1R Pumping Plant site.
(2) Current Investigations. - Investigations were conducted during the winter of 2000-2001 by the Four Corners Construction Office - Farmington (FCCF) to explore pipeline lateral alignments and pumping plant sites. The investigations consisted of 72 hollow stem auger holes, DH-B9-67 through DH-B9-150. Drill holes DH-B9-100, -117, -136, and -137 are not included as they were drilled on features that have since been deleted from the project. Surface geologic mapping was also conducted along the pipeline lateral alignments and at pumping plant sites. Geologic logs from these test borings are included in Division 14 and are shown on Location of Exploration drawings G2 (809-D-6199) and G4 (809-D-6201). Geologic mapping and stick log data are provided on the plan and profile drawings 4 (809-D-6037) through 22 (809-D-6055).
(3) Testing and Sampling. - All of the subsurface investigations were conducted using a 6.25-inch inside diameter hollow stem auger system. Samples were collected with a 5.0-inch inside diameter split tube sampler or a 5.0-inch inside diameter acrylic sleeve sampler. Testing conducted included in-place density, Proctor, Atterberg Limits, and gradation analysis. Lab testing of field samples was conducted by the FCCF Laboratory.
Final geologic logs and physical property testing summary sheets for the investigations located along the alignments of the features are included in Division 14. Results of the testing are included in the logs of exploration, and are summarized in Table 1C below. For General Geologic Legend, Explanation and Notes, see drawing G1 (809-D-6198). For location of explorations, see drawings G2 (809-D-6199) and G4 (809-D-6201). Drill hole locations are given by station and distance left (LT) or right (RT) of centerline. The Unified Soil Classification System (USCS) was used for material identification and descriptions.
