Case Study – Advancing BIM for Bridges: Kiewit’s integrated Engineer-Contractor perspective

Building Information Modeling (BIM) is reshaping infrastructure delivery. While BIM adoption in vertical construction is well established, its application to bridges is advancing rapidly as agencies and industry recognize its value beyond visualization. BIM for bridges is a data‑driven delivery platform that supports collaboration, constructability, and informed decision‑making throughout the asset lifecycle.

At Kiewit, integrated delivery is fundamental to how we work, and BIM is a key enabler. This presentation provides an executive overview of BIM for bridges, including:

• What BIM means in the bridge context
• Key terminology and expectations (3D, BIM, MALD, Digital Twins, OpenBIM/IFC, LOD)
• 3D, 4D, and 5D BIM demands within Kiewit
• Benefits, challenges, and current limitations
• National efforts advancing BIM for bridges through AASHTO, FHWA, DOTs, and industry partners
