Davis & Floyd identified an efficient method of data collection by reviewing existing design plans, as-built plans, previous inspection reports, and SCDOT standard plans. Our team conducted site assessments to verify bridge dimensions and conditions of structural components as well as documented additional characteristics that contributed to overall load-carrying capacity.

Our team of structural engineers used this data to calculate the load rating factors for each bridge while considering over 40 different loading scenarios and rating levels. Using these factors, our team identified bridges that did not meet the load-carrying capacity for current regulations in South Carolina and provided SCDOT with recommendations for new weight restrictions. Using the data collected, we provided recommendations to update the National Bridge Inventory (NBI), documenting the current conditions of each bridge.
