Construction-Ready Digital Terrain Models

The construction industry’s use of digital terrain models (DTMs) has dramatically improved production and efficiency. KYTC designers and consultants, however, have confronted obstacles in their efforts to use DTMs effectively. Specifically, the rapid proliferation of and advances in DTM technology have made it difficult to consistently prepare construction-ready DTMs for Cabinet inspectors and contractors. That is, while designers incorporate the necessary level of detail into their DTMs to complete a design, when DTM files are handed over to inspectors or contractors, they require significant adjustments or reformatting to render them usable, or they are scrapped entirely. Editing and reformatting DTMs is time-consuming and hinders project execution. KYTC will benefit from guidance that assists designers in preparing DTMs that are properly formatted, contain an appropriate level of detail to enable their immediate use in the field, and require minimal editing.
