National infrastructure condition analysis applying published ASCE Report Card methodology and federal inspection data to bridges, water systems, roads, and energy grids.
Trellison Institute applies the grading methodology published by the American Society of Civil Engineers (ASCE) in their quadrennial Infrastructure Report Card, along with published frameworks from the Federal Highway Administration (FHWA), EPA, and Army Corps of Engineers. Trellison Institute has not contacted ASCE and does not claim endorsement or affiliation. We apply their published grading criteria because they represent the most widely recognized framework for assessing national infrastructure condition. Negative results are results.
ASCE estimates the United States faces a $2.59 trillion infrastructure investment gap over the next decade. Their Infrastructure Report Card grades 17 categories of infrastructure from A to F based on condition, capacity, funding, future need, operation and maintenance, public safety, resilience, and innovation.
Trellison applies this published grading framework to publicly available federal inspection and condition data, enabling researchers and policymakers to analyze infrastructure condition at the state, county, and facility level — a granularity the national Report Card does not provide.
County-level infrastructure grading — apply ASCE grading criteria at granularities below the national level, identifying communities with the worst infrastructure conditions relative to their population and economic base.
Investment gap modeling — structured pipelines for estimating infrastructure investment needs by category, state, and county using published ASCE cost models.
Bridge and dam risk assessment — analysis tools for identifying structurally deficient bridges and high-hazard dams with overdue inspections or deteriorating condition ratings.
Water system vulnerability — compliance violation analysis, lead pipe exposure estimates, and infrastructure age assessment for drinking water systems serving environmental justice communities.
This service is free for infrastructure researchers, civil engineers, and policy analysts whose methodology passes Trellison's evaluation criteria. We provide the data infrastructure. Researchers provide the expertise and the questions. We do not advocate for specific infrastructure policies — we measure what the data shows about condition and need.
