We have a unique insight into the needs and expectations of government clients based on our extensive work experience with GDOT and other DOTs in the southeastern United States. This puts us in a position to provide QA/QC services, where we proactively keep up with rigorous standards, guidelines, and policies, and perform meticulous technical reviews to examine and verify conformity, delivering a standard of uncompromising diligence.
With us as your QA/QC partner, you are guaranteed unwavering quality, which instills confidence and drives continuous improvement, elevating the reliability and trustworthiness of project outcomes.
Soil Survey Studies
Our Soil Survey Study services provide the critical geotechnical data needed to design and construct
safe, durable, and cost-effective roadway foundations. We evaluate subsurface soil and rock conditions,
groundwater, and material properties to develop sound geotechnical recommendations. Analyses
address settlement, slope stability, and constructability, and we adhere to client standards such as
GDOT 810 soil classification to ensure compliance.
Through field reconnaissance, subsurface exploration, and laboratory testing, we identify potential
challenges, including weak or variable soils, slope instability, inundated conditions, or high moisture
content. When poor soils are encountered, we recommend ground improvement, stabilization, or
alternative earthwork approaches to optimize constructability and long-term performance.
All findings and recommendations are compiled in a comprehensive Soil Survey Study report, with our
engineers available to provide support during construction, ensuring a seamless transition from
investigation to project delivery.
Bridge Foundation Investigations (BFI)
We deliver comprehensive Bridge Foundation Investigation (BFI) services for bridge replacement,
rehabilitation, and expansion projects. The process starts with our evaluation of existing foundation
types, dimensions, and capacities through detailed records review and engineering assessment, taking
that knowledge into account when designing the foundations for the new or replacement bridge
structure. We develop practical and cost-effective foundation recommendations supported by field
reconnaissance, thorough subsurface investigations, subsurface material evaluation, and rigorous
foundation analyses. We are experienced in performing BFIs using both Allowable Stress Design (ASD)
and Load and Resistance Factor Design (LRFD) methodologies to meet project-specific and agency
requirements.
All findings and recommendations are clearly documented in a Bridge Foundation Investigation report,
with our services concluding upon delivery of a final BFI report accepted by the client. Beyond reporting,
our engineers remain available to provide trusted technical support during construction, ensuring
continuity from investigation through project delivery.
Wall Foundation Investigations (WFI)
Our Wall Foundation Investigation (WFI) services focus on evaluating subsurface and foundation
conditions that influence the performance and constructability of retaining walls and other earth-
retaining structures. Investigations address existing conditions where applicable and emphasize shallow
foundation behavior, including bearing capacity, settlement, differential settlement and overall stability.
For proposed wall systems, our team characterizes subsurface materials through field reconnaissance,
targeted subsurface exploration, and detailed material evaluation to support foundation design. We
provide engineering analyses and recommendations for shallow foundations and, where poor or
marginal soils are present, assess and recommend ground improvement or other mitigation measures to
achieve project performance requirements.
Results of the investigation are summarized in a Wall Foundation Investigation report documenting
subsurface conditions, analyses, and design recommendations. Services are completed upon delivery of
a final WFI report accepted by the client, with continued engineering support available during
construction to address field conditions and design-related questions as they arise.
Culvert Foundation Investigations (CFI)
Our Culvert Foundation Investigation (CFI) services are designed to assess the subsurface and
foundation conditions critical to the design, performance, and longevity of culvert structures. We
evaluate soil and foundation characteristics that influence bearing capacity, settlement and scour
susceptibility. Our approach combines field reconnaissance, targeted subsurface exploration, and
detailed material evaluation to inform foundation design. When shallow weak soils are encountered, we
provide solutions such as ground improvement or deep foundations to ensure reliable performance
under anticipated loads and hydraulic conditions.
All analyses and engineering recommendations are compiled in a comprehensive Culvert Foundation
Investigation report. Our services conclude with the delivery of a final CFI report accepted by the client,
and our engineers are available to provide technical support during construction to address any field
conditions or design adjustments that may arise.
High Mast Lighting Foundation Investigations (HML)
Our High Mast Lighting (HML) Foundation Investigation services evaluate subsurface conditions and
foundation performance to support safe, stable, and long-lasting high mast pole structures.
Investigations assess axial capacity and lateral stability while ensuring the foundation can sustain torsion
and bending moments.
We provide recommendations for shallow or deep foundations options to
achieve required performance. Findings and recommendations are documented in a final HML
Foundation Investigation report accepted by the client, with our engineers available to provide support
during construction as needed.
Support Services
We supplement our clients' resources by providing on-demand consultant talent, tailored to their specific needs.
We currently provide the following support service:
Staff Augmentation
We currently provide this service for diverse professional roles. This embodies our commitment to comprehensive assistance in every facet of project execution. By bridging talent gaps and enhancing project capabilities, we foster efficiency, innovation, and success for our clients, providing the vital resources needed to propel their vision forward.
Construction Services
Avaabi Consulting Ltd offers comprehensive quality assurance and control services throughout
all project construction phases, ensuring impeccable standards and specification compliance.
We currently provide the following construction services:
Construction Materials Testing (CMT)
This encompasses a suite of essential testing procedures designed to ensure the durability, safety, and compliance of materials used in road, bridge, and other infrastructure construction projects. Through rigorous testing protocols, including assessments of asphalt, concrete, soil, aggregates, and more, these services guarantee that materials meet stringent regulatory standards and project specifications.
By conducting comprehensive analyses, such as compaction, strength, density, moisture, and much more tests and evaluations, construction materials testing services play a pivotal role in enhancing the longevity and performance of transportation and other infrastructure, safeguarding public safety and investment.
Construction Engineering and Inspection (CEI)
We provide critical oversight and support throughout the construction phase of road, bridge, and other infrastructure projects. From construction inception to completion, these services ensure adherence to design specifications, regulatory requirements, and industry best practices.
Skilled engineers and inspectors provide on-site supervision, quality control, and documentation, verifying the integrity of construction materials, adherence to safety protocols, and compliance with project schedules.
By facilitating seamless coordination between stakeholders, resolving construction challenges, and conducting thorough inspections, these services uphold the quality, safety, and efficiency of transportation and other infrastructure projects, ultimately enhancing their long-term performance and reliability.
