5D virtual construction will transform the construction industry
Redesign should take place on the computer, not on the construction site.
5D virtual construction modeling, or 5D BIM (short for building information modeling) enables the various participants of a construction project—from designers and contractors to owners—to visualize and display the entire construction progress sequentially over time, factoring in a critical component: actual and forecasted costs. It has the potential to vastly transform the delivery of projects large and small.
Here’s how BIM technology has progressed through the years:
3D: Three-dimensional design modeling that enables project visualizations, walkthroughs, clash detection, and item scheduling
4D: 3D modeling plus time, linking the project schedules: resources, tasks, etc.
5D: 4D plus cost, integrating design with estimating, scheduling, and costing
Leveraging the data available in the 3D BIM model, 5D BIM optimizes construction project management, enabling project team members to visualize the progression of construction activities and the associated costs. Beyond the ability to maximize physical and constructability constraints, 5D virtual construction gives companies the ability to better manage budgets and forecasted expenditures. Understanding construction sequencing can help prevent problems related to constructability and optimize cash flow within the framework of construction sequencing.
In today’s environment, many E&C companies and some owners have begun to adapt and adopt 5D into their work processes. Recent surveys predict that 100 percent of owners and 80 percent of contractors will use BIM in some way in 2014.
there is no standard definition of BIM and many partial or incomplete
solutions. Dual standards have been developed by different organizations such
as the Industry Foundation Classes (IFC) by the buildingSMART allianceTM
and ISO 15926. The number of developers in the BIM space has also grown
creating integration issues.
For visualization to drive projects from concept to completion and into operations and maintenance, developers must extend current BIM capabilities. Users need mapping and display capabilities between the embedded construction schedule and the 3D model. They need easy, effective ways to verify clearances, identify design incompatibilities, and detect clash or collision points.
All construction contractors are currently investing in standalone, specialized niche technology, so now is the time to bring those niche technologies together in an interoperable environment.
