Christian Wheeler Engineering

Geotechnical investigations, geohazard evaluations, and design recommendations tailored to specific project sites.

• Geotechnical Investigation

  Subsurface investigation and laboratory testing programs tailored to specific sites and building types. Services include identifying geologic units and evaluating hazards such as seismicity, liquefaction, slope/bluff instability, groundwater, compressible soils, rock rippability, and corrosivity to provide recommendations for foundations, grading, and slope stabilization.

• Geotechnical Construction Observation

  Field observations and compaction testing during grading, remedial grading, slope stabilization, and foundation excavation to confirm anticipated conditions and support design adjustments.

• Geologic Consulting

  Comprehensive engineering geology evaluations, hazard assessments, and geologic mapping.

• Due-Diligence Geotechnical Evaluations

  Preliminary geotechnical assessments and feasibility studies during early-stage property acquisition and planning.

• Settlement Monitoring

  Instrumentation and precise monitoring of structural and soil settlements over time.

• Slope Monitoring

  Slope stability assessments, instrumentation, and ongoing monitoring for landslide-prone areas.

Comprehensive consulting, design review, observation, and field testing for building envelope, waterproofing, and roofing systems.

• Design Phase Consulting

  Review of basis-of-design materials, specifications, and drawings, as well as performing redline reviews, value engineering, and constructability reviews specific to the building envelope.

• Construction Administration Phase Consulting

  Assistance in reviewing and responding to contractor requests for information (RFIs), product data submittals, and shop drawings, alongside leading preconstruction meetings.

• Quality Assurance Observation Services

  Quality assurance observations during the construction of building envelope, waterproofing, and roofing systems to support compliance with approved design plans.

• Field Testing Services

  In-situ performance testing of building envelope, waterproofing, and roofing assemblies.
