AYOPP LC offers engineering services with a primary focus on Geotechnical Engineering, Environmental Consulting, Water Resources and Construction Support. Our work is rooted in time-tested engineering principles, technical accuracy, and a steadfast commitment to public safety and project performance.
Our Areas of Expertise
We specialize in delivering tailored engineering solutions for public agencies, private developers, contractors, and design professionals. Our core services include:
Dredging design & Soil Mechanics
Coal Combustion Residuals and Tailings Remediation
Slope Stability Analysis & Landslide Remediation
Earth Retention Design
Culvert & Drainage System Engineering
Hydrology & Water Resources Planning
Construction Quality Assurance
Whether you're constructing a pond, culvert, utility infrastructure of conducting environmental remediation, AYOPP provides the technical insight and dependable support every step of the way.
In-House Soil Testing Laboratory
In-House Soil Testing Laboratory
To maintain a high level of quality control, AYOPP operates an equipped soils testing laboratory, managed by licensed Civil Engineers. Our lab adheres to ASTM and AASHTO testing protocols, providing accurate and timely results for:
Soil classification (Unified/USCS and AASHTO)
Compaction testing (Proctor – standard and modified)
Atterberg limits
Grain size distribution (sieve and hydrometer analysis)
Permeability, consolidation, and other specialized tests
This integrated capability allows us to deliver fast turnaround time, consistent data interpretation, and tighter project coordination.
Site and Subsurface Investigations
Site and Subsurface Investigations
Before a single yard of concrete is poured or steel driven, it is essential to understand what lies beneath the surface. Our geotechnical investigations involve: By characterizing the ground properly, we ensure that structures are supported on firm, well-understood foundations, reducing risk of future settlement, structural failure, or unanticipated costs.
Infrastructure Design & Public Safety
Infrastructure Design & Public Safety
Geotechnical engineering is critical in the planning and development of infrastructure. We evaluate ground stability, predict deformation, and design site-specific solutions to withstand real-world stresses, natural and man-made alike.
Managing Natural Hazards
Managing Natural Hazards
Nature cannot be controlled, but it can be understood, planned for, and mitigated. Our engineers are experienced in analyzing terrain and geological hazards, including:
Landslides and slope failure
Erosion, scour, and sediment transport
Flooding and stormwater infiltration
We assess soil behavior under extreme conditions and design engineering controls such as:
Engineered slopes
Retaining walls and ground anchors
Surface and subsurface drainage systems
Ground improvement and stabilization techniques
Dewatering and evaporation ponds design
While we embrace new technologies and evolving analytical tools, we remain grounded in the fundamental truths of soil behavior, engineering judgment, and real-world constructability.
Our philosophy is simple: build with confidence by understanding the ground beneath your feet.
Working Together Toward Better Outcomes
Working Together Toward Better Outcomes
AYOPP engineers work in close collaboration with architects, structural engineers, planners, developers, and public agencies to ensure that every project meets its technical, economic, and environmental goals.
Our process emphasizes:
Thoroughness in investigation
Soundness in design
Clarity in communication
Practicality in implementation
AYOPP: Engineering You Can Trust
AYOPP: Engineering You Can Trust
At AYOPP LC, we don’t cut corners because we understand the price of failure. We believe in doing it right the first time. Whether you're planning a subdivision, retrofitting aging infrastructure, environmental cleaning or responding to a geologic hazard, you can count on us to provide dependable geotechnical support, backed by decades of experience and a reputation for integrity.
If you build it, they will come.
