Geotechnical Engineering
Geotechnical Engineering is a crucial field of expertise for Qpoint Group, focusing on the behavior of earth materials and their impact on construction and environmental projects. Here’s a brief summary:
Site Investigation: Conducting detailed assessments of soil, rock, and groundwater conditions to inform project design and planning.
Foundation Design: Developing safe and efficient foundation solutions for structures, considering factors such as soil stability and load-bearing capacity.
Slope Stability Analysis: Evaluating the stability of natural and artificial slopes to prevent landslides and erosion.
Ground Improvement: Implementing techniques to enhance the properties of soil and rock, ensuring the stability and safety of construction projects.
Environmental Impact: Assessing and mitigating the environmental effects of geotechnical activities, such as excavation and earthworks.
By leveraging their geotechnical engineering expertise, Qpoint Group helps clients ensure the safety, sustainability, and success of their projects while minimizing environmental risks.

QPoint Service Areas
1. Subsurface Investigations & Site Characterization
This is the “bread and butter” service. Before a client builds, they need to know what’s underneath the surface to avoid costly surprises.
-
Drilling and Sampling: Standard Penetration Testing (SPT) and Cone Penetration Testing (CPT).
-
Test Pitting: Physical excavation to observe shallow soil strata.
-
Laboratory Testing: Analyzing soil samples for moisture content, plasticity (Atterberg limits), shear strength, and consolidation.
-
2. Foundation Engineering & Design
Once the soil properties are known, you advise on how to keep the building standing.
-
-
Shallow Foundations: Design for spread footings or mat foundations.
-
Deep Foundations: Recommendations for driven piles, drilled shafts (caissons), or micropiles.
-
Settlement Analysis: Predicting how much a structure will sink over time and ensuring it stays within safe limits.
-
3. Slope Stability & Earth Retention
Crucial for projects involving hillsides, embankments, or deep excavations in urban areas.
-
Landslide Evaluation: Assessing the risk of slope failure and designing remediation.
-
Retaining Wall Design: From simple gravity walls to complex mechanically stabilized earth (MSE) walls.
-
Excavation Support: Designing shoring systems, soldier piles, and lagging to protect adjacent structures during construction.
4. Pavement Evaluation & Design
Providing specifications for roads, parking lots, and runways to ensure they don’t crack or rut under traffic loads.
-
Analysis of subgrade CBR (California Bearing Ratio) values.
-
Life-cycle cost analysis for asphalt vs. concrete.
5. Construction Quality Assurance (CQA)
Acting as the client’s eyes and ears on-site to ensure the contractor is following the geotechnical specs.
-
Compaction Testing: Using nuclear gauges to verify soil density.
-
Foundation Inspections: Verifying pile depth or checking the cleanliness of a drilled shaft before pouring concrete.
-
Instrumentation: Monitoring vibrations, tilt, or groundwater levels during construction.
