2026 ACEC-NH & NHDOT Technical Exchange Conference

Session 4A: NHDOT CADD Update
Speaker: Bill Caswell, NHDOT
- In this presentation, Bill will provide an update on the status of NHDOT’s CAD/D system. This is an exciting time as NHDOT was recently awarded an ADCMS grant for development of intelligent digital models among other things. The presentation will discuss the status of the ADCMS grant project, recent CAD/D developments and future plans.

Session 4B: Bentley Update
Speaker: Volaree Rendon, Bentley Systems
- This presentation explores the Levels of Digital Maturity required for transportation agencies to transition from traditional plan-centric delivery to data-centric digital delivery, ultimately enabling models as legal deliverables. It outlines a practical four-level framework that organizations can follow, beginning with foundational planning and governance, advancing through the use of models and data as Reference Information Documents (RID), piloting Model as Legal Deliverable (MALD) workflows, and ultimately reaching a stage where the model itself becomes the legal document supporting project delivery and asset lifecycle management. The session will also provide an overview of Bentley Infrastructure Cloud, highlighting how integrated capabilities across ProjectWise, iTwin, and digital delivery workflows enable organizations to manage information, collaborate across stakeholders, and operationalize model-based delivery. The concepts will be illustrated through a real-world implementation example from the Floyd Hill Project delivered with Colorado Department of Transportation and AtkinsRéalis, demonstrating how digital delivery practices, cloud-based collaboration, and model-centric workflows can transform project execution and lay the foundation for full lifecycle infrastructure intelligence.
