Geotechnical Investigations. Engineer and its geotechnical drilling sub-consultant will perform a geotechnical investigation along the proposed alignment to observe subsurface conditions and support the design of the new gravity sewer. Engineer assumes the entire alignment will be constructed by open-cut, with the exception of the US-70 road crossing. All borings are assumed to be performed in unpaved areas. The scope of the subsurface investigation will consist of the following: Perform Standard Penetration Test (SPT) borings at approximately 500-foot-intervals along the alignment. Up to 16 borings will be drilled. In general, drill depths will extend to 2 feet below the proposed pipe invert. Observe and log soil and groundwater conditions in all borings. SPT split-spoon sampling will be performed in general accordance with ASTM D1586 and soil samples will be given a USCS classification. Where refusal is encountered above the planned depth of boring, rock coring will be performed to at least a depth of 2 feet below the proposed pipe invert. For trenchless borings (US-70), rock coring will be performed to extend borings to the shaft bottom. Borings where the pipe is proposed to be installed via open-cut will be backfilled with cuttings. Borings at the proposed trenchless crossing will be backfilled with grout. Conduct laboratory testing on selected soil samples to confirm soil classification, estimate engineering properties, and determine suitability for re-use as backfill materials. Upon completion of the geotechnical investigation, Engineer will prepare a geotechnical data report summarizing the subsurface conditions observed in the borings and containing all data (boring logs, laboratory testing, etc.) collected during the investigation. Horizontal location of the test hole shall be located using GPS services.
Geotechnical Investigations. The Contractor performs his own geotechnical site investigations he considers necessary to assist in the design of his works. The Contractor identifies and specifies all work and tests to be done. Geotechnical information provided to the Contractor during the tender phase is only for tender purposes and the Contractor is required to verify all geotechnical investigations to be conducted and condition during the execution of the project. The Contractor accepts full responsibility for all ground conditions and provides adequate foundation design.
Geotechnical Investigations. We have added Yeh & Associates to our team to provide a program of data review, field exploration, laboratory testing, and engineering analysis necessary to support the design of the project. They will document the findings from the geotechnical investigations in a design geotechnical report. Geotechnical consultation will be provided through the preliminary design and bidding phases, as needed. A copy of Xxx’s proposal is included as an attachment to this Proposal.
Geotechnical Investigations. The Xxxxxxx Group (Xxxxxxx) will drill and observe ten air‐track borings to depths of approximately 15 feet below ground surface along the sewer alignments for Xxxxxxx, Stonehaven, TriPeaks, Forum, and Desert Skies alignments. Xxxxxxx will prepare traffic control plans for City approval and will provide traffic control during boring activities, and will clear drilling locations for underground utilities using a utility locator. Xxxxxxx will prepare a technical memorandum to summarize the subsurface conditions, where explored, and provide geotechnical recommendations.
Geotechnical Investigations. The proposed project is to remove the existing single-lane bridge crossing of Xxxxx Creek and replace it with a new bridge structure. The existing railroad flatcar bridge is 120-feet long and 13-feet wide. According to Caltrans bridge inspection reports, the existing foundations are spread footings at the abutments and steel H-piles at the piers and the structure is considered scour critical. Geologic mapping shows the site at the contact between Jurassic-Cretaceous Fransican Formation and Plio-Pleistocene Non-Marine sediments. The alluvial sediments are typically not associated with Naturally Occurring Asbestos (NOA) but this will be evaluated during the ISA. Bedrock is not exposed in the channel and bedrock may be deep below ground surface based on the surrounding terrain and geologic mapping. Bridge structure type has been tentatively defined in the RFP. It is indicated to be a reinforced concrete slab bridge in the range of 150±ft long and 22±ft wide supported on reinforced concrete wall-abutments. Suggested foundation types in the RFP include driven piles or CIDH piles to 60-ft depths. Depending on the consistency of the Plio-Pleistocene materials and the scour potential for the bridge, spread footings may also be a viable alternative for the bridge. Abutment locations and depth of pile caps will be established, in part, on the basis of projected channel grade and bank slope configuration/stability. It is assumed that abutments will be located at equal distances from the thread of the channel. Bridge line and grade are expected to generally match existing roadway. The existing roadway approaches appear to be on native ground (terrace materials) and it is understood that the roadway will be widened to accommodate wider travel lanes and shoulders.
Geotechnical Investigations. ⮚ Conduct geotechnical investigations at the pump station site to support the preliminary design of proposed improvements. Services shall include the following items: ⮚ Perform a site reconnaissance at the pump station to observe current conditions and evaluate access to the site for future exploration equipment. ⮚ Review available site documentation and existing literature, including publicly available USDA county soil maps, USGS geologic maps, and/or available drillers well logs to provide initial background data collection. ⮚ Prepare a geotechnical memorandum to summarize the geologic review, site reconnaissance, relevant historical explorations, and anticipated subsurface conditions to support the preliminary design. The memorandum will include recommendations for subsurface investigations to support the final design and construction of the pump station. An electronic copy of the draft memorandum will be prepared and submitted for review and comment. A final report will be prepared following receipt of comments for the draft memorandum.
Geotechnical Investigations. 1. Collect previous historical geotechnical data and reports, maintenance records and other data from the City. Extract all boring/exploration maps and laboratory data from the available documents.
Geotechnical Investigations. 1. Drill twenty-four borings (24) throughout the project area. Each boring will be drilled to rock or maximum depth of 15-feet, whichever occurs first. For the purpose of this fee determination a depth of 12-feet is assumed. Rock coring is not included. All borings will be drilled in pavement areas accessible to the drill rig. Work will be coordinated with City Inspector.
Geotechnical Investigations. 3.1 The contractor shall be responsible for detailed Geotechnical investigations at the proposed solar project site/s for the purpose of foundation design for various buildings, structures, HT lines, MMS etc. and other design/ planning requirements. The investigation work shall be carried out through NABL accredited agency. The contractor shall submit the credentials along with relevant certificates in support thereof for verification/ approval of the Investigation Agency by the Engineer in-charge.
