Geotechnical Analysis. Sampling and analysis of soils and hydrologies, and subsequent reporting and recommendations, upon which architectural and engineering designs may be based. Applicable to Construction Stage observation, testing, and reporting of soils conditions, including testing for types and quality of fill material and its installation, compaction, soil density testing, caisson borings inspections, cut and fill monitoring, etc.
Geotechnical Analysis. The geotechnical analysis shall be based on both the currently available geotechnical site information and the results of the new field investigation. The following items shall be addressed by the geotechnical analysis:
Geotechnical Analysis. The Contractor shall provide geotechnical services for design elements consisting of, shallow infiltration, pavement widening and signal pole design. This task includes the following: Coordinate and manage the field investigation, including locating utilities, access preparation, and scheduling of contractors and GeoDesign staff. Prepare traffic control plans and obtain right-of-way permits from City. Prepare boring location and test location exhibits for the City use in obtaining Permit- of-Entry on private properties. Drill four (4) soil borings to depths of up to 30 feet below ground surface for use in signal pole design at the intersection of NE Xxxx Road and NE Xxxxxxx Boulevard. Assume up to 15 feet of rock coring at each exploration. Complete two (2) hand auger explorations to depths of up to ten (10) feet below ground surface (or refusal if encountered at a shallower depth) for use in retaining wall design. Perform infiltration testing in the hand auger borings at the depth requested (up to 10 feet below ground surface) to evaluate the option for infiltrating from shallow xxxxxx. Complete four (4) pavement explorations in the existing pavement to depths of up to 10 feet below ground surface (or refusal if encountered at a shallower depth) for use in pavement widening design. Perform dynamic cone penetrometer (DCP) testing in each of the pavement explorations. Maintain a detailed log of each exploration, visually classify the soil encountered, obtain soil samples as appropriate for the soil conditions encountered, and observe groundwater conditions in each exploration. Conduct the following laboratory tests using soil samples obtained from the explorations: o Moisture Content tests in general conformance with American Society for Testing and Materials (ASTM) D 2216 o Atterberg limit tests in general conformance with ASTM D 4318 o Grain size determinations, combined sieve and hydrometer, in general conformance with ASTM D422 Project management including attendance at a project kick-off meeting and up to five
Geotechnical Analysis. Two structural borings as well as a boring near the stream bed will be completed by our subconsultant, Wang Engineering to determine the stream material for the scour critical analysis. A detailed scope of work by Xxxx is attached. Xxxx anticipates the need to conduct the borings on the O’Brien Road pavement, which will require temporary lane closures and traffic control. The bridge overlay material and bearing pads will be evaluated for asbestos materials. If these cannot be eliminated by review of existing plan details, the HMA overlay material will be sampled and tested for asbestos material. HLR’s work efforts will include coordination of Xxxx’x work with the requirements of the project and review of the results of the borings. Task 5 – Hydraulic & Drainage Design HLR will obtain the FEMA Category 6 Flood Insurance Study Data files in digital or printed format (USGS information is not necessary). HLR will conduct a field review of the site and then create an existing (baseline) conditions hydraulic model. This model will be used to evaluate the scour critical evaluation of the existing pile foundations and to model the hydraulics of alternative proposed bridge rehabilitation design. It is anticipated that the proposed deck replacement will not modify the existing hydraulic conditions. HLR will also develop a preliminary plan for the localized drainage on the roadway approaches. Compensatory storage and stormwater detention requirements (if needed) will be developed based on the recommended bridge design alternate and will adhere to the McHenry County Stormwater Ordinance. HLR will develop and prepare the project Hydraulic Report in the IDOT BLR format and will summarize the results in the IDOT Waterway Information Table, coordinating this effort with McHenry County. A Scour Evaluation will be completed for the proposed structure, including recommended riprap countermeasures. HLR will also develop a preliminary plan for the localized drainage along the roadway approaches. HLR will develop and prepare the Preliminary Bridge Design and Hydraulic Report in the IDOT BLR format. Results will be summarized in the IDOT Waterway Information Table, coordinating this effort with McHenry County. Task 6 – Preliminary Structural Design & Bridge Condition Report HLR will investigate alternate types of superstructures and make recommendations based on the economics, durability, aesthetics and compatibility to the site and stream conditions. It is anticipated that two ...
Geotechnical Analysis. The CONSULTANT shall: • Review pertinent background data, including in-house geotechnical data, readily available soils reports for sites near the proposed Project, aerial photographs, and published geologic maps and soils data. • The site is near a fault line which may necessitate a fault study if one was not completed in a previous geotechnical investigation on file.
Geotechnical Analysis. A. Development Suitability - Soils in the District will be analyzed to determine the suitability of site soils for development. Where possible, existing geotechnical reports on file with the City or made available by owners in the District will be used as the basis for this summary. The goal will be to identify any areas where redevelopment may be difficult or precluded due to soil conditions, as well as to provide a general picture of the soil bearing capacities in the district, including depth(s) to bedrock.
Geotechnical Analysis. The Department will complete a subsurface investigation in the area. Geotechnical laboratory testing will be performed for soil classification to provide engineering parameters for geotechnical design.
Geotechnical Analysis. 2.3.1 The ENGINEER will utilize a subconsultant to perform geotechnical analysis to determine an asphalt pavement recommendation and soil information for the design of headwalls at up to seven (7) culvert crossing locations.
Geotechnical Analysis. The Sponsor must provide a written commitment to obtaining geotechnical data that will be sufficient to establish initial construction elevation for all phases of the Bank. The geotechnical analysis must be provided to CEMVN no later than four months following administrative release of credits for any phase of the Bank. Failure to provide the geotechnical analysis will result in removal of the administrative credits from the Bank’s ledger. Additional information regarding the specifics of the required geotechnical analysis is located in Attachment C.
Geotechnical Analysis. Using the aforementioned survey and geotechnical information an analysis of the slope stability will be performed. The analysis will include: • Determine cross section and stratigraphy at one location. • Develop soil parameters at the cross-section location. • Slope stability analysis at the cross-section location. Analysis and Meeting. Once we have reviewed the available data, collected survey information and completed our slope stability analysis, we will coordinate a meeting with the City to discuss the results of our analysis and potential mitigative actions.
