GEI delivers practical digital solutions that integrate engineering expertise, data science, and software development to enable confident, well-supported decision-making for clients across complex water, environmental, and infrastructure systems.
GEI supports federal, state, and local agencies; utilities; and resource managers who face growing technical complexity, tighter regulatory scrutiny, and increasing demands for reliable, real-time information. We synthesize data, models, and engineering insights into usable digital solutions that improve planning, operations, and long-term program delivery, with a clear path to sustained, mission-critical use over time.
Our teams build digital solutions that fit how people work. We develop custom applications, analytics, and decision support systems that integrate with existing workflows and data environments—whether you need a targeted tool for a single project or an enterprise platform that scales across a program. Throughout delivery, we prioritize transparency, usability, and maintainability along with governance, traceability, and controlled change so clients can adopt solutions with confidence and sustain them over time.
Custom Software and Application Development
GEI develops custom software applications that support engineering analysis, operational decision-making, and program management. Our team designs and builds solutions ranging from focused data-processing tools to complex, enterprise-scale engineering applications. Each solution is tailored to client needs, emphasizing usability, performance, and long-term maintainability.
We support the full application lifecycle—from defining requirements and system architecture through design, development, testing, deployment, documentation, training, and production support. We design solutions to be durable, extensible, and compatible with evolving client technical environments to protect client investments and enable future enhancements.
Key strengths include:
• Desktop and web-based applications
• Client–server and cloud-enabled systems
• Real-time data collection and processing
• Secure data access, versioning, and archiving
• Advanced visualization, mapping, and user interfaces
• Distributed, scalable computing and data processing environments
Our engineers and developers work closely with domain experts to ensure that software solutions are grounded in sound engineering principles and aligned with regulatory and operational realities.
Decision Support Systems and Operational Tools
GEI designs decision support systems (DSS) that help clients evaluate alternatives, understand tradeoffs, and respond to changing conditions. Integrated data management, modeling, visualization, and analytics produce intuitive tools that support real-world decisions. These tools scale across programs by coordinating data, models, services, and applications into cohesive, enterprise-scale integrated systems.
Clients use GEI decision support tools for reservoir operations, flood risk management, dam safety, groundwater management, and emergency response planning. We keep decision-makers “in the loop” by making assumptions, uncertainty, and model behavior visible and understandable.
Our capabilities include:
• Real-time operational dashboards
• Scenario evaluation and strategy testing
• Integration of forecasts, monitoring data, and model results
• Visualization of system performance and consequences
• Support for adaptive and risk-informed decision-making
These tools are designed to evolve over time, allowing clients to incorporate new data, updated models, and changing objectives without rebuilding systems from scratch.
AI, Data Science, and Advanced Analytics
GEI applies artificial intelligence (AI), machine learning, and data science techniques to help clients extract insight from large, complex datasets and improve decision-making under uncertainty. Our approach emphasizes transparency, sound analytical practices, and alignment with engineering insight and judgment.
We develop AI-enabled tools that complement—not replace—physics-based models and expert analysis. We select methods based on the decision need, data quality, and risk profile of the application.
Applications include:
• Time-series forecasting and anomaly detection
• Surrogate modeling to accelerate computationally intensive simulations
• Image and document classification using satellite, drone, and sensor data
• Large language model (LLM) tools for extracting structured information from unstructured documents
• Recommender systems to evaluate large decision spaces
• Reinforcement learning for adaptive, sequential decision-making
GEI applies these techniques with disciplined validation, uncertainty awareness, and clear documentation so clients can act with confidence.
Information Management and Data Integration
Effective decision-making depends on well-organized, accessible, and trusted data. GEI develops information management systems that capture, integrate, and manage engineering and scientific data across projects and programs.
Our team establishes common data frameworks using proven technologies, industry standards, and public-domain tools where appropriate. We design systems that protect client investments in data while improving accessibility and usability across technical staff, managers, and stakeholders.
Services include:
• Database design and data governance
• Data validation, quality control, and organization
• Web-based reporting and visualization
• GIS-enabled data management and mapping
• Secure access controls and role-based permissions
• Integration with modeling and analytics platforms
By aligning information management with engineering workflows, GEI helps clients turn data into a durable asset that supports both day-to-day operations and long-term planning.
Numerical Model Integration and Enhancement
GEI integrates advanced numerical modeling capabilities into digital tools that improve usability, performance, and decision relevance. Our team has extensive experience developing and enhancing numerical models for water resources, environmental systems, and infrastructure applications.
We support a wide range of numerical techniques and model architectures, including finite difference, finite element, and finite volume methods; optimization and uncertainty analysis; ensemble simulation; and statistical and time-series analysis. In many cases, we develop pre- and post-processing tools that make sophisticated models more accessible to users, enabling efficient scenario analysis and clearer interpretation of results.
GEI’s engineers have contributed to the development of nationally recognized modeling tools and continue to support clients in applying models effectively within planning, regulatory, and operational contexts.
