Case Study: Granite Construction achieves safer highway expansion planning with Exodigo

Granite Construction resolves 2 unmapped lines with Exodigo

Granite Construction, working on the Highway 288 expansion for TxDOT in Houston, faced the challenge of mapping critical underground utilities across swampy terrain with a high water table. These conditions rendered traditional ground-penetrating radar (GPR) unreliable, leaving the team without accurate data on two deep crude oil pipelines and other unknown utilities, which posed significant safety and environmental risks for the project.

Exodigo implemented its non-intrusive, multi-sensor scanning approach to create a verified composite utility map. The solution successfully identified two previously unmapped lines, confirmed the exact depth of the crude oil pipelines, and caught a conflict with a planned bridge foundation. These results allowed Granite and TxDOT to revise construction plans proactively, avoiding potential utility strikes and enabling safer excavation. Exodigo's technology provided the precise intelligence needed to protect both the crew and the project's bottom line.
