The year was 2005. The project was the U.S. Federal Courthouse in Jackson, Miss. The decision, made by the U.S. General Services Administration at the end of design development, was to turn the 400,000-sq-ft facility into a GSA poster child for building information modeling. The design team would create a coordinated BIM and use it to produce 2D contract documents. The team would also provide its BIMs to the construction manager-general contractor, as reference material only, for use during construction.

The main lesson learned by the construction manager who recently completed a pioneering four-year, BIM-enabled project to build a replacement ballpark for the New York Yankees is “the more trades modeling, the merrier,” says James Barrett, manager of virtual design and construction for Turner Construction Co., the CM at-risk. But more doesn’t necessarily mean more complex, in terms of interoperabilty, anyway. Building on the experiences with the Yankees project, Barrett says Turner is satisfied for now to see subcontractors building their own models and working with their tools of choice, at their preferred levels of detail beyond a minimum standard,
Sutter Health’s Digby Christian is dead serious about delivering the $320-million replacement for Sutter Medical Center Castro Valley on time and on budget in 2013. But he also is not kidding, and sees no contradiction, when he refers to the 223,500-sq-ft job as a living laboratory. In its most ambitious experiment yet, Sutter is going beyond building information modeling’s low hanging fruit—clash detection—and exploring BIM-based estimating, automated code checking and direct digital-model exchange for detailing, coordination, automated fabrication and scheduling. The nonprofit hospital owner wants to prove it is possible to reduce waste and risk while delivering a better facility,

Building information modeling has come a long way recently, but it is still far from being business as usual. That, and lack of BIM software interoperability, were about the only two subjects of general agreement regarding BIM among the 60 attendees of a recent “eConstruction” roundtable, in Phoenix. As recently as two years ago, there were no model BIM contracts and most designers did not have staff trained on BIM, said John Cross, a vice president of the American Institute of Steel Construction, Chicago, which cohosted the March 31 session with the American College of Construction Lawyers. Work-flow efficiency is
With a trend toward integrated project delivery gaining traction, project teams are clamoring for a free flow of data between disciplines. In its latest response to the evolving market needs, on Feb. 9, San Raphael, Calif.-based Autodesk Inc. presented 2010 versions of its architecture, engineering, construction and geospatial products, as well as civil design software for transportation and utilities, with changes designed to ease the adoption of building information modeling processes within and across those sectors. The most ubiquitous change, as presented in a web conference showcasing key features of the new releases, is the replacement of tool bars across
As we approach the second decade of the 21st Century it might be time to adjust our industry's cliches and adages. With the advancement of Building Information Modeling, better known as BIM, the construction industry will simply revisit the "smart board" instead of going "back to the drawing board."
