Description of Services

Reliance Engineers Inc. offers comprehensive geotechnical engineering services tailored to the demands of infrastructure development, deep foundation systems, and complex ground behavior. Our geotechnical expertise is grounded in rigorous analysis, site-specific evaluations, and a commitment to practical, constructible solutions. Below is a technical breakdown of our core service offerings:

Subsurface Investigations and Site Characterization

We begin each project with a detailed understanding of subsurface conditions. Our geotechnical team develops and manages robust site investigation programs to assess soil, rock, and groundwater properties. Services include:

• Borehole drilling, sampling, and classification
• In-situ testing (SPT, CPT, pressuremeter, dilatometer, permeability)
• Laboratory testing for strength, compressibility, and hydraulic properties
• Geophysical surveys and correlation with boring data
• Development of detailed geotechnical baseline reports (GBRs) and interpretive reports

Foundation Engineering and Bearing Capacity Analysis

We provide design recommendations for shallow and deep foundations, tailored to project-specific load demands and subsurface conditions. Our services include:

• Bearing capacity evaluation for spread footings and mats
• Settlement analysis for short- and long-term performance
• Global and local stability assessments
• Raft and mat foundation design support
• Pile group interaction and load-transfer analysis

Slope Stability and Embankment Design

Our team performs advanced slope stability analyses to support cut slopes, embankments, and natural terrain stabilization. We provide:

• Static and seismic slope stability modeling using limit equilibrium and finite element methods
• Design of geosynthetic-reinforced slopes
• Embankment foundation improvement and staged construction sequencing
• Design of buttresses, berms, and toe drains

Seepage and Groundwater Control

Understanding and managing groundwater is essential in all phases of geotechnical design. We provide:

• Seepage modeling using finite element tools
• Groundwater inflow estimation and control for excavations
• Design of cut-off walls, relief wells, and drainage systems
• Hydrostatic uplift analysis and mitigation
• Construction dewatering system design and monitoring

Retaining Structure Support and Load Evaluation

Our geotechnical input supports the performance of permanent and temporary retaining systems. We provide:

• Active, passive, and at-rest earth pressure calculations
• Backfill and drainage recommendations
• Soil-structure interaction modeling for walls and foundations
• Influence of surcharge loads and adjacent structures
• Construction impact assessments for adjacent buildings and utilities

Geotechnical Instrumentation and Performance Monitoring

We incorporate instrumentation programs into our geotechnical designs to monitor performance and validate design assumptions. We provide:

• Design and specification of instrumentation programs (inclinometers, piezometers, strain gauges, extensometers, etc.)
• Installation support and monitoring schedules
• Interpretation of data and performance reports
• Threshold exceedance protocols and response recommendations

Geotechnical Peer Reviews and Value Engineering

Reliance Engineers provides third-party peer reviews and independent geotechnical assessments. Our goal is to ensure technical rigor, optimize design performance, and reduce construction risk and cost. We offer:

• Design verification and constructability reviews
• Value engineering support for alternate foundation and ground improvement systems
• Independent technical advisory for public and private clients
