Geotechnical Exploration. The Lessee may only conduct geotechnical exploration activities performed in support of plan (i.e., SAP and/or COP) submittal in locations where an analysis of the results of geophysical surveys has been completed. This analysis must include a determination by a Qualified Marine Archaeologist as to whether any potential archaeological resources are present in the area. Except as allowed by the Lessor under 4.2.6, the geotechnical exploration activities must avoid potential archaeological resources by a minimum of 50 meters (164 feet), and the avoidance distance must be calculated from the maximum discernible extent of the archaeological resource. A Qualified Marine Archaeologist must certify, in the Lessee’s archaeological reports, that geotechnical exploration activities did not impact potential historic properties identified as a result of the HRG surveys performed in support of plan submittal, except as follows: in the event that the geotechnical exploration activities did impact potential historic properties identified in the archaeological surveys without the Lessor’s prior approval, the Lessee and the Qualified Marine Archaeologist who prepared the report must instead provide a statement documenting the extent of these impacts.
Geotechnical Exploration. 4.3.4.1 The Lessee may only conduct geotechnical exploration activities in support of plan submittal in locations where an archaeological analysis of the results of geophysical surveys has been completed. This analysis must include a determination by a Qualified Marine Archaeologist as to whether any potential archaeological resources are present in the area that could be impacted by bottom- disturbing activities.
Geotechnical Exploration. After the Preliminary Engineering Report identifies, and the SAIG approves the preferred alternative, geotechnical field exploration shall be performed to evaluate subsurface conditions and develop geotechnical recommendations for sewer installation including irrigation canal and railway crossings using trenchless, horizontal drilling technology. Geotechnical exploration tasks will include: Prepare exploration and testing work plan, including traffic control and health & safety plans; Field locate and establish exploration coordinates; Drill, log, core and sample six boreholes to depths of 20 feet; Perform geotechnical laboratory analyses of soil and rock samples in accordance with standard ASTM methods; Geotechnical engineering analysis and evaluation of trenchless technology applicability; Prepare Draft Geotechnical Exploration Report for city and design team review and comment; Respond, resolve and incorporate comments into Final Geotechnical Exploration Report.
Geotechnical Exploration. The Consultant will obtain Santa Xxxxx Valley Water District (SCVWD) drilling and encroachment permits prior to performing our field exploration. Two cone penetration test (CPT) probes will be advanced to depths of up to approximately 60 feet in locations near the north and south bridge abutments. The empirical data will be reviewed in the field and a direct push probe will be advanced adjacent to each CPT probe to collect soil samples at selected depths as needed. Soil samples will be taken for visual classification and laboratory testing. Resulting holes will be backfilled in accordance with Santa Xxxxx Valley Water District (SCVWD) requirements. Soil samples will be re-examined in the laboratory to verify field classifications and will be tested for moisture content, Plasticity Index, gradation, corrosion, and other physical properties as appropriate. Based on the geological and geotechnical data gathered, a geotechnical exploration report will be prepared, to address the following: • Suitability of the site for the proposed pedestrian bridge. • Physical properties of the typical soils encountered. • Assessment of geological/ geotechnical hazards at the subject site, including compressible soils and l iquefiable soils, as appropriate. • Foundation recommendations for the bridge abutments. • Caltrans ARS curves. • L- pile input information and group effect considerations. • Recommendations for wing wall design.
Geotechnical Exploration. The COUNTY agrees to provide the following information and services to the ENGINEER in connection with the work at no charge:
Geotechnical Exploration. The Geotechnical engineer will obtain soil samples in the field. The final number and location of geotechnical borings will be determined on site by the geotechnical engineer. Care will be taken to minimize damage to property during the geotechnical exploration. Any damage will be restored to the pre‐exploration condition by the geotechnical engineer. Boring holes will be backfilled with cutting, clay, plugs and/or other material as determined by the geotechnical engineer. Boring locations will be illustrated in the geotechnical report.
