5D virtual construction will
transform the construction industry
should take place on the computer, not on the construction site.
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.
BIM technology has progressed through the years:
3D: Three-dimensional design modeling
that enables project visualizations, walkthroughs, clash detection, and item
4D: 3D modeling plus time, linking
the project schedules: resources, tasks, etc.
5D: 4D plus cost, integrating
design with estimating, scheduling, and costing
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
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.
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.
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.
