For years, building information modeling and 3D-engineered models have been available to provide extra information and visualization assistance on road and bridge projects. Bui primed 21) plans have largel) remained the contractual deliverable for construction. Now, though, many states and agencies across the U.S. are beginning to explore a model-based delivery approach, steadily leaving 2D plans behind in favor of an all-digital delivery. HDR, a global engineering, architecture, environmental, and construction services firm, works with stale departments of transportation across the country, and a growing number of agencies have either begun requiring model based deliverables or plan 10 within the next five years. Many of these entities are working on pilot projects that move them toward a model-based delivery future. And national organizations, such as the American Association of State Highway and transportation Officials, the Transportation Research Board, and the National Institute oi Building Sciences are dedicating significant resources to developing best practices and national standards. |
