Contractors building one of the largest and tallest pediatric research hospitals, hemmed in on a tiny site in Chicago, say they are several months ahead of schedule in part due to the owner�s requirement that designers and contractors collaborate using building information modeling, a digital tool that helps prevent errors. However, the use of BIM apparently still has some growing up to do. For the 1.25-million-sq-ft hospital that stands 457 ft tall on just 1.8 acres, the building team not only is tackling the challenges of urban, vertical hospital construction, it also is conducting research to determine if the time

Building information modeling, still relatively rare in the transportation construction world, proved key in gaining public approval for a planned $573-million, 9.4-mile rapid-transit bus system in Hartford, Conn. Advocates hope transit agencies will begin to ramp up use of BIM in future projects. Slide Show Image: SEA Three-dimensional imaging proved a valuable public-outreach method. The Connecticut Dept. of Transportation had planned on design-build for the line connecting Hartford and New Britain. “We had a designer bring the project from [environmental permitting] to 30% design,” says Michael Sanders, ConnDOT transit administrator. But after then-Gov. John Rowland (R)—who had approved special design-build

Athird of the engineers surveyed in recent market research on building information modeling say they get a negative return on BIM investments; a fifth say they break even. The perceived return on investment for architects is better, with 19% saying they have a negative ROI and 23% saying they break even. BIM value for owners and contractors is perceived as much greater, at about 70% ROI. + Image Source: McGraw-Hill Construction “Engineers are the most pessimistic about the value of BIM, with 12% saying they see no meaningful value from it,” according to a market report, “The Business Value of

Virtual design and construction tools are crossing over from buildings to transportation projects. Officials admit that 3D parametric modeling in the transportation sector has trailed the buildings sector, but they say change is afoot. “In 10 years, we will be living in a BIM world,” predicts Cosima Crawford, chief engineer for the New York City Transit Authority. “It’s our new reality,” she says.That reality has transportation teams tackling the same challenges their building counterparts are seeing in their transition to building information modeling. These include BIM technology issues, process change and institutional buy-in. Image: NYC Transit Authority For new projects,

Virtual design and construction is gaining ground in the utilities markets because of its ability to speed large-scale planning and development of energy projects. Though current applications on projects have just begun to touch the full potential of the approach, experienced users are enthusiastic about the financial benefits of debugging a project by building it first on the computer.

Attention building-information-modeling rookies: Experiences of BIM veterans in the following pages of ENR may save you from reinventing many spokes on the still-rickety wheels of the wagon rolling toward glitch-free use of high-tech tools to make building design and construction less bumpy. The first piece of advice to first-time travelers down the BIM road is to get BIM’s equivalent of driving lessons and roadside assistance. Warning: If you go it alone, you may get into serious trouble. Even modeling veterans can benefit from a BIM “global positioning system.” The helpers call themselves BIM managers or model integrators. The name doesn’t

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,

One lesson learned from the Walsh Group’s construction- management assignment on a 650,000-sq-ft hospital in Elgin, Ill.—a project Walsh took over as mass excavation and steel procurement were under way—is that a lack of team experience with building information modeling should not be an inhibiting factor on a complex construction project. image: Walsh Construction Photo: Walsh Construction In some areas ducts hung below plumbing because pipe lead times were less.
