Additional Experience and Role Accountabilities
• This role requires demonstrated experience with geotechnical design for Stations and associated facilities for operating voltages from 60kV to 500kV in an electric utility environment.
• Prepare project documentation and deliverables in accordance with BC Hydro project and Engineering Design Practices (i.e. evaluation reports, specifications, proposals, estimates, design basis', calculations, hazard logs, test plans).
• Prepare design work packages including scope, duration, and level of effort estimates.
• Prepare signed and sealed engineering deliverables as a Professional Geoscientist and as a Professional of Record (PoR) in accordance with EGBC and BC Hydro Design Practices.
• Provide technical assistance and construction support in the field, and undertake field reviews as required by EGBC.
• Prepare designs for existing and new facilities.
• Undertake site investigations of surface and subsurfaces to establish geotechnical ground conditions and soil classification.
• Perform various in situ field tests such as standard penetration test, cone penetration, dynamic cone penetrometer.
Perform tasks in the field for laboratory soil testing.
• Undertake analysis for design of structures associated with Transmission Stations including termination structures, buildings, access, for shallow (i.e. grillage) and deep (i.e. piles) foundations.
• Prepare reports for internal and external clients detailing investigations, evaluation, analysis, conclusions, and recommendations.
• Provide technical guidance and review of designs prepared by others following established practices.
• Manage design tasks including scope, schedule, and cost.
Examples of Owner's Engineer review and acceptance tasks:
A. Site Specific Seismic Ground Response Analysis including: a) applicability of seismic scenarios (shallow, inter-slab and Cascadia types) and selected historical earthquake for a given site when the site response is being modeled, and b) dynamic ground motion response analysis using 1-D wave propagation program SHAKE®.
B. Post-seismic stability of foundations and foundation soils if found susceptible to loss of strength during a seismic event.
C. Design of Ground Improvement (GI) work such as vibro-replacement, deep soil mixing, jet grouting or dynamic compaction.
D. Detailed and standardized terrain mapping (following EGBC’s guidelines).
E. Conducting WEAP analysis and preparing Pile Load Testing program for a given project.
Examples of Engineer of Record tasks:
1. Site investigation program including: i) devising drilling and in-situ testing plan including CPT, ii) setting up instrumentation installation and its monitoring plan, and iii) devising index and advanced lab testing plan
2. Settlement calculation and preload design, including wick drain design, instrumentation set up and its monitoring program.
3. Foundation design input such as: bearing capacity, uplift capacity, lateral capacity (for shallow foundation of tower structures) including passive and base resistances, frost depth and estimation of adfreezing forces.
4. Conventional pile design (driven steel piles and augered CIP as examples) including those that need to tolerate seismic loadings when soil is identified as liquefiable.
5. Helical pile/pier preliminary design including Test Pile and Load Test plan.
6. Slope stability analysis for static and pseudo-static cases.
7. Characterization of native soils to be used as backfill including: a) fine-grained soil and devising its installation QA plan, b) very coarse grained (Proctor non-compliance material) soil and devising its installation QA plan.
8. Identification of the following risk and recommending engineering solutions to mitigate them: ARD/ML, groundwater, shoring, corrosivity, sulphate attack, swelling.
9. Assessment of the likelihood of liquefaction, strain softening and cyclic mobility risks. If either of these risks exists, estimate: a) the extent of the risk zone, and b) post-seismic horizontal and vertical displacements (total and differential) and c) lateral spreading, if applicable.
