Integrated computing systems and methods for applying sub-surface material location and composition information to engineering plans for designing, highways and other roadways, are provided. Utilizing the described systems and methods, surfaces, highways, may be more efficiently designed in a timely fashion, requiring less format conversion for inputs and outputs to be compatible throughout the design process. Additionally, adjustments for changes in alignments for the desired surfaces are more easily taken into account than in conventional design systems, permitting quicker design corrections and more accurate results.
