Geotechnical Investigation and Report. The Consultant shall coordinate with Ninyo and Xxxxx, a geotechnical subconsultant, to perform a geotechnical investigation. Through its subconsultant, the Consultant shall: • Provide a geotechnical report for the project area to identify and assess potentially adverse conditions, such as ground fissures, the location of mapped faults, and/or areas of known collapsible or expansive soils. • Obtain necessary permits, notify Underground Services Alert, and provide traffic control and plans as necessary to conduct the field exploration. • Selected samples of the soils and rock (if encountered) obtained from the borings will be tested in a laboratory to determine relevant engineering properties of the on-site soils. Testing will be performed under the direction of a geotechnical engineer, in general accordance with applicable AASHTO, NDOT or accepted local standards. Perform laboratory tests to evaluate physical and engineering properties of the subsurface soils, including in-place moisture content and density, gradation, Atterberg limits, expansivity, solubility, and chemical (salt) considerations. Selection of tests will be based primarily on project needs, actual soil conditions encountered during the drilling activities, and quality and quantity of samples recovered from the planned soil borings. • Address field exploration and laboratory test results in a formal report. The report shall contain the following: o Summarize geologic literature and other available geotechnical reports or studies in the area.
Geotechnical Investigation and Report. CTL Xxxxxxxx (CTL) will be responsible for design level geotechnical investigation for the roadway design, including borings and subsurface exploration with laboratory test results, and pavement designs for asphalt and concrete pavement sections. Boring will be provided for the bridge design and the roadway section between the Bridge and Xxxxx Avenue. Ten (10) borings are included in this phase of work and will denote groundwater levels. A summary report with recommendations will be provided. Additional borings between Jefferson Street and the Bridge will be performed at a later date under separate agreement. Percolation testing is not included in the base scope and fee but can be provided if requested.
Geotechnical Investigation and Report. The CONSULTANT shall make or cause to be made, a complete roadway geotechnical investigation to be in accordance with INDOT’s Geotechnical Manual, 2018 edition of which a copy is on file with the Indiana Department of Transportation and same is incorporated herein by reference and is made a part hereof.
A. Prior to making the borings, the CONSULTANT shall submit boring specifications and boring locations and sketches for approval by the LPA. Borings shall extend sufficiently in depth to obtain characteristic data for the proper design of the pavement. The CONSULTANT shall backfill bore hole or cause to be backfilled in accordance with Aquifer Protection Guidelines, dated October 30, 1996. A copy of the document is on file with the Indiana Department of Transportation, Division of Materials and Tests, Geotechnical Section.
B. The CONSULTANT will provide equipment, labor, and associated materials to drill and sample twenty-six (26) soil borings to a depth of 5 feet and four (4) to a depth of 20 feet.
C. All borings will be continuously sampled with 2.5-foot long split barrel samplers in the upper 10-feet and at 5-foot intervals thereafter.
D. Split spoon samples will be obtained according to the Standard Specification AASHTO T-206-03 “Penetration Test and Split-Barrel Sampling of Soils.” As needed, Shelby tubes will be obtained for the consolidation testing and resilient modulus determination according to the Standard Specification AASHTO T-207-03 “Thin- Walled Tube Sampling of Soils.” Bulk samples will be obtained for CBR testing.
E. The soils-testing program will include natural moisture content, Atterberg limits, particle size analysis, organic content (if needed), pH determination, unconfined compressive strength, hydraulic conductivity, one-dimension consolidation, CBR value, and resilient modulus determination.
F. The geotechnical report will include a detailed description of the project, field and laboratory testing procedures, a characterization of the soil and groundwater conditions, and recommendations for the design and improvements. The report will also contain a site location map, and a summary of laboratory test results. The results of the field exploration and laboratory tests will be used in the engineering analysis and written report. Specifically, the report will include soil and groundwater conditions, subgrade, and foundation bearing recommendations for culvert wing and headwall to assist the design engineers in preparing the trail paveme...

Geotechnical Investigation and Report. This task will consist of a geotechnical investigation of up to 10 test pits to a depth of 5 to 15 feet (or practical refusal if encountered at a shallow depth) along the length of the shared use path at approximately 2,000 foot intervals and at the bridge site, and logging of the test pits. The Field Investigation includes: • USA dig clearance • Location of test pits • Test pit excavation • Observation of test pits • Soil sampling • Water table measurement, if encountered Lumos will collect samples at regular intervals and note the existing soils conditions at each excavation. Lumos will provide the excavation services, and notify USA Dig. Soils will be classified in accordance with the Unified Soil Classification System (USCS). Lumos will perform engineering analyses and calculations, and develop a Geotechnical Investigation Report that will discuss the geologic setting, exploration and site condition, field and laboratory test data, and our conclusions and recommendations from a geotechnical perspective. Our Geotechnical Investigation will be supervised by a Registered Professional Civil Engineer in the State of Nevada and will specifically include the following services: Laboratory analysis may include: • Direct shear • R-Value • Atterberg limits • Grain size analysis (including fines content) • Expansion index • pH, Soluble sulfate and resistivity Report, Recommendations, and Conclusions: • Table of contents • Exploration logs – which will include test results, and depth of test pits • Site conditions • Field investigation • Soil types and classifications • Laboratory analysis and test results which will include sample locations (P.I, % passing #200, grain size analysis, R-Value) • Grading recommendations • Trail structural section recommendations • Portland Cement Concrete recommendations • Foundation recommendations, including bearing capacity and settlement • Rockery retaining wall recommendations and calculations • Ground water depth, if encountered • Test pit location map • Slope stability analysis in critical areas • Signature sheet which will include preparer’s signature and Engineer’s professional stamp Excavation equipment will use existing access roads and the proposed trail alignment to the greatest extent possible; however, some ground disturbance outside the trail limits will be required in order to perform the geotechnical investigation. , DELIVERABLES: Geotechnical Investigation Report in hardcopy (3 copies) and .pdf format.
