Detailed Research Methodology and Data Validation
Primary Research
Mordor analysts spoke with state transportation budget officers, Class-I freight rail planners, tier-one civil contractors, and airport program managers across the South, Midwest, and Pacific regions. Their insights clarified bid price escalation, typical lead times, and the share of design-build contracts, allowing us to fine-tune cost curves and validate our assumed project pipelines.
Desk Research
We began with government sources that track hard spending, such as the United States Department of Transportation, the Bureau of Transportation Statistics, the Federal Transit Administration, and the Federal Aviation Administration. State DOT capital plans, the American Road & Transportation Builders Association outlook, and U.S. Census 'Value of Construction Put in Place' tables gave timely contract values that anchor our base year. Additional context came from trade associations like the American Association of Port Authorities and open customs data that show maritime cargo flows.
Company 10-Ks retrieved via D&B Hoovers, news archives on Dow Jones Factiva, and patent trends (Questel) helped us size private participation and emerging technologies (for example, advanced bridge materials). These examples illustrate our secondary inputs; numerous other public and subscription datasets were reviewed to cross-check figures and fill gaps.
Market-Sizing & Forecasting
A top-down model starts with federal and state capital outlays, which are adjusted for the share that flows to the four asset classes before being further filtered through historical payout schedules. We then corroborate these totals with bottom-up indicators, sampled highway lane-mile additions, rail track extensions, terminal gate counts, and sampled average construction cost indices to ensure internal consistency. Key variables feeding the model include IIJA annual authorizations, state fuel-tax receipts, passenger enplanements, port TEU throughput, and Bureau of Economic Analysis price deflators. Multivariate regression, confirmed by expert consensus, projects each driver to 2030 and produces the CAGR used in our forecast horizon. Where individual state data were missing, interpolation relied on nearby states' spending ratios that share similar population density and asset age profiles.
Data Validation & Update Cycle
Outputs pass three tiers of review: automated variance checks against historical ranges, peer review within the construction vertical, and a final sign-off by a senior analyst. Our team refreshes every report annually and re-contacts sources if federal appropriations, major contract awards, or material cost swings exceed preset thresholds.
Why Mordor's US Transportation Infrastructure Construction Baseline Earns Trust
Published estimates often diverge because firms mix spending, asset value, and operations in different ways and apply varying refresh cadences.
Key gap drivers include scope breadth, treatment of repair spending, and forecast discipline. Other publishers may roll maintenance and operational outlays into capital totals or count full life-cycle costs, which inflates the headline figure, whereas Mordor Intelligence focuses strictly on construction value put in place during the build or major rehabilitation phase.
