Answer: CTDOT is currently migrating its CAD software from Bentley Systems V8i Select Series platform to the CONNECT Edition platform (this includes the transition from InRoads to OpenRoads Designer). One of the main drivers of this transition is due to Bentley Systems discontinuing support for its V8i products. This means that although V8i versions will still function in its current configuration, Bentley will not continue to certify it on future versions of the Windows Operating System.
In addition, CTDOT sees the advantage and the need to move into a 3D model-centric environment. This will allow CTDOT to increase productivity, reduce design errors, and adhere to industry trends of AMG (Automated Machine Guidance), eConstruction and Asset Management. As the transportation industry worldwide adapts to new technology, Transportation Agencies must ascertain their readiness to adapt to these industry trends. FHWA has elevated 3D modeling through its Every Day Counts initiative and has encouraged Transportation Agencies to adopt policy for delivering a digital product in lieu of a set of plans (paper, mylar or PDF). When a project is designed using current civil design software, it is created within a 3D model. Contractors across the world are utilizing 3D models for Automated Machine Guidance to perform activities such as grading, paving and drainage installation. In between these steps, projects are often flattened to convey design intent in a 2D medium such as a PDF or paper plan set. During this conversion, data is lost, precision is reduced and design intent is nullified. Looking forward, CONNECT Edition products will allow designers to produce a product that retains the civil data and design intent through construction. This data, also known as Electronic Engineering Data (EED), can be consumed further downstream in Asset Management and Maintenance. However, for now, CTDOT recognizes that the contract document shall remain a PDF set of plans.
