Exploration sites

Providing advanced analyses often using finite element methods for well pads to determine the amount settlement the rig structure may experience during heavy drill stem pulls and provide recommendations for stabilization if required.

Environmental Services

We provide Phase 1 and Phase 2 environmental site assessments for proposed new construction, property condition assessments, active or inactive well sitesl as well as soil and groundwater monitoring and testing for proposed or existing locations.

 Access roads

Analyze potential access roads into new or existing well sites using the BLM “Gold Book” as a reference guide while working closely with the producer and BLM staff.

Horizontal directional drill sites

Perform exploration of HDD sites and provide recommendations that are project specific and based on the soil and rock encountered for HDD drillers.

Process plants

Perform advanced exploration and analyses for the design of oil and gas processing plants to reduce risk and increase cost effectiveness. Construction observation follows these recommendations and designs to help ensure the construction is of high quality and therefore relatively problem free throughout the design life of the project.

Phase 1 and Phase 2 Environmental Site Assessments (ESA)

Environmental Sampling

Multi-Unit Shop Buildings

Small to Large Retail Spaces and Developments

Provide services for these facilities using advanced exploration and engineering analyses. Typical facilities and commercial sites include warehouses and small to large scale retail developments. These sites are often new locations without site improvements but, forensic investigations and recommendations for retrofitting and remodeling existing facilities are also performed.

Phase 1 and Phase 2 Environmental Site Assessments (ESA)

Environmental Sampling

Construction observation for the project specializing in foundation and pavement observation is also offered.

Small to Large Scale Subdivisions 

Single Family Residences 

Distress Evaluations

Residential projects are carefully evaluated using advanced techniques because we understand that a client’s home is the most important project. AGS further understands that overly conservative recommendations and designs may be the difference between being able to afford new home construction or not. Recommendations are provided that ensure the longevity and safety of your home yet are affordable and realistic for your life.

County Road Design

 Local Road Design

 Paved and Gravel Road Design

 Specializing in Soft and Difficult Subgrades

Road sections are designed using a variety of exploration and engineering analyses. Explorations typically include soil type, California Bearing Ratio (CBR), Falling Weight Deflectometer (FWD), and Ground Penetrating Radar. In addition, visual observations and roadway evaluation equipment can also be utilized.

Existing dams can be evaluated for safety based on a wide variety of analyses including visual observations, in-situ water levels, piping, slope inclinometers, and slope failure.

Distressed Buildings

Distressed Slopes

Our knowledge of proper analyses and best industry practices has helped us to become an Expert Witness in the engineering and construction industries. Additionally, we use these experiences to continually evaluate our processes and practices.

We provide a wide range of construction observation services to help ensure your project is constructed to meet the plans and specifications. These services include: 

• drilled pier observations
• helical screw pile observations
•       steel reinforcement observations
• density of soil, aggregates, and asphalts, concrete tests
• proof rolls
• observations of soils to confirm design parameters.

Additionally, our laboratory can perform all of the common tests for construction materials including gradations, proctors, plasticity tests, etc.

Evaluate prospective project locations on a larger scale to determine if a site is suitable for the proposed construction. These typically include making observations of geologic hazards such as expansive or collapsible soils, potential for slope failures, and type of bedrock and corresponding properties.

Phase 1 and Phase 2 Environmental Site Assesments (ESA)

Environmental Sampling

We provide exploration and geotechnical engineering for airports, runways and hangars that meet stringent FAA design requirements.

An element of AGS’s practice is environmental services. We perform investigations for potential buyers, sellers, and refinancing. These services may be as simple as an ASTM Phase I Environmental Site Assessment or a complex Phase II Environmental Site Assessment investigation requiring subsurface investigation.  AGS addresses the engineering and regulatory aspects of evaluating a property for environmental concerns using proper ASTM and CERCLA requirements. We are aware of the time and confidentiality constraints that may accompany significant commercial real estate or corporate acquisitions, and we are ready for the task. These services include:

Transactional Screens for Limited Environmental Due Diligence

Phase 1 environmental site assessments

• Commercial Properties
• Oil and Gas Assets
• Vacant Lands

Phase 2 environmental site assessments

• Soil Sampling
• Groundwater Sampling
• Subsurface Investigations

Soil and Groundwater Monitoring and Testing

Property Condition Assessments

Natural Slopes

Embankments

Distress Evaluations

Landfills

Dams

Retaining Walls

Natural and manmade slopes are analyzed in a multi-step process starting with advanced exploration and engineering analyses to accurately assess the geometry and strength of the soil materials. The information is then input into a state-of-the-art software program to evaluate the stability. Soil materials include native soils, fill soils and often include geosynthetic layers for various containment projects.

If slopes require a retaining wall to meet project needs, recommendation and design can be provided.
