At AYOPP, we offer comprehensive 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 you need—every step of the way.

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 faster turnaround times, consistent data interpretation, and tighter project coordination.

Site Investigations: Building from the Ground Up

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

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

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 and rockfall protection
  
  

• Retaining walls and ground anchors
  
  

• Surface and subsurface drainage systems
  
  

• Ground improvement and stabilization techniques
  
  

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.
