Geotechnical Engineering Analysis Clause Samples
The Geotechnical Engineering Analysis clause defines the requirements and procedures for evaluating the physical properties of soil and subsurface conditions at a project site. Typically, this clause outlines the scope of investigations, such as soil sampling, laboratory testing, and reporting, and may specify the standards or methodologies to be followed. By establishing clear expectations for geotechnical analysis, the clause helps ensure that design and construction decisions are based on reliable data, thereby reducing the risk of unforeseen ground conditions and associated project delays or cost overruns.
Geotechnical Engineering Analysis. The Consultant will compile and evaluate the field and laboratory data collected during the Geotechnical Site Investigation. Geotechnical engineering analysis will include evaluating seismic/liquefaction hazards, creating earth pressure diagrams for retaining wall design, temporary excavation, construction dewatering, and pavement restoration.
Geotechnical Engineering Analysis. Conduct geotechnical evaluations and analyses to support the new structure foundation systems for the proposed Emergency Operation Center and Outdoor Area canopies. Consultant shall:
(a) Develop subsurface profiles and cross-sections based on the available borings;
(b) Evaluate soil bearing capacity, subgrade modulus and static total, and differential settlements for the proposed new foundations for outdoor area canopies;
(c) Evaluate pile foundation bearing capacity and lateral load resistance for the new operation center;
(d) Select potential seismic sources and design earthquakes using code-based (2014 OSSC) probabilistic approach;
(e) Provide lateral earth pressures for below-grade wall design, including active, at-rest, seismic, and passive pressures if required; and
(f) Provide lateral load resistance recommendations, including passive earth pressure and coefficient of friction.
Geotechnical Engineering Analysis. Consultant will complete a geotechnical analysis, provide design parameters and provide design and construction recommendations based upon the field investigation and laboratory test results. The engineering evaluation and analyses will be performed in accordance with the IBC 2015. The geotechnical analysis will include the following:
1. Recommendations for earthwork including site preparation, excavation, cut and fill slopes, structural fill material, fill placement, compaction, and wet weather construction; An evaluation of onsite materials for use as structural fill onsite and in the trail embankment;
2. A site-specific seismic hazard evaluation will be performed including the peak horizontal acceleration on rock for 2475-year return period ground motion (IBC2015), applicable Seismic Performance Category, and site hazards due to potential liquefaction and lateral spreading;
3. Evaluation and development of recommendations for bridge foundation design;
4. Design and construction recommendations for fills and approach embankments including global stability, settlement, and bearing capacities.
1. Geotechnical analysis results and all design and construction recommendations to be included in the 100% Geotechnical Design Report Portland Parks & Recreation Exeltech Consulting, Inc. ▇▇▇▇▇▇▇▇▇▇▇▇ Park Pedestrian Bridge Replacements Scope of Services
Geotechnical Engineering Analysis. Evaluate Field and Laboratory Data: Based on the borings and the geotechnical laboratory test results of selected samples, HWA will generate estimates of the soil strength and other properties needed to evaluate the effects the subsurface conditions will have on the proposed improvements. • Develop Geologic Cross-Sections: HWA will construct a geologic cross-section along the centerline of the project. This cross-section will show soil conditions along the bridge alignment and will be provided in a geotechnical report. • Generate AASHTO Seismic Design Parameters: Based on the soils encountered along the alignment, HWA will determine the Site Class for seismic design. The design spectral acceleration parameters will then be selected in accordance with the AASHTO Specifications for Roads and Bridges. • Evaluate Slope Stability: HWA will evaluate the global slope stability of the steep slopes to identify potential impacts on the project. Results of the field reconnaissance, exploration, and testing programs will be incorporated into the analysis. Global stability will be evaluated using the limit equilibrium approach under both static and seismic loading conditions. Additionally, HWA will evaluate the anticipated stability of the proposed eastern bridge approach. • Evaluate Soils for Liquefaction and Lateral Spread Potential: HWA will evaluate the susceptibility to liquefaction of the soils along the bridge alignment for the design event required by AASHTO. Once the susceptibility to liquefaction is determined, we will evaluate the potential for lateral spreading. • Evaluate Soils for Settlement Potential: HWA will evaluate the subsurface soil conditions for settlement potential. If compressible soils are present, HWA will conduct settlement analysis associated with various bridge configurations. • Conceptual Ground Improvement Evaluations: HWA will evaluate the subsurface soil conditions and determine if ground improvements are expected to be required to support the design and construction of the proposed improvements. If ground improvements are needed, HWA will provide concept-level recommendations to support the TS&L evaluation. • Evaluate Bridge Foundation Vertical Capacity: ▇▇▇ will perform analyses of foundation vertical capacities using accepted drilled shaft and/or spread footing estimation methods provided in the AASHTO LRFD Bridge Specifications and the Washington State Department of Transportation (WSDOT) Geotechnical Design Manual (GDM). • Evaluat...
Geotechnical Engineering Analysis. 18 Results obtained from the field investigation and laboratory testing shall be used to characterize subsurface 19 soils and conditions and create idealized profiles for design purposes. The following analyses in accordance 20 with CALTRANS standards shall be performed for the project: 21 Evaluate seismicity, estimate Peak Ground Accelerations, and determine an Acceleration Response 22 Spectrum (ARS) curve. 23 Evaluate liquefaction potential and seismically-induced settlement. 24 Determine axial and lateral capacity of bridge foundations. 25 Evaluate settlement and global stability of new or widened embankments.
Geotechnical Engineering Analysis. Engineering studies and analyses will be accomplished that will lead to the preparation of conclusions and recommendations concerning (1) earthwork including cut and fill slopes, wet-weather construction considerations, suitability of on-site soils for use as structural fill, and import fill criteria;
