In a 3D building model, individual objects can be digitally linked with the time element from a construction schedule to enable project managers to play the construction sequence for review. This mechanism is termed 4D CAD, where the fourth dimension is time...

Not that long ago, most building professionals would have classified sustainable design merely as an interesting idea. But awareness of climate change and other environmental issues has catapulted it to center stage. The international movement toward sustainability has created a flood of new green building regulations and initiatives around the globe and sustainable design practices -- once considered niche -- are now widespread...

It’s the last lesson of the day at Ridgewood School in Doncaster, but not all the kids in year 11 are going home yet. Sixteen pupils will be hard at work until at least 5 o’clock, not because they have been put in detention – this is their GCSE construction class.

This afternoon, Ridgewood’s 15 and 16-year-olds are being introduced to building design programme Autodesk Revit. Sitting in rows in the glass-fronted modern engineering block, the pupils’ eyes are glued to their flatscreen monitors, with only a low murmur of voices as they tweak their on-screen house designs. One student is planting six fir trees around a one-storey house. Another is putting the finishing touches to a roof...

Like many architecture firms, FOX Architects of McLean, Va., and Washington, D.C., has decided that making the transition from CAD to building information modeling (BIM) is a strategic business imperative. The 80-person multidisciplinary firm (architecture, interior design, landlord services, graphic design, and multimedia design) is engaged in a transition process that will unfold over the course of the coming year and beyond, and has generously agreed to allow, for the purposes of this column, the broadest possible access to the firm’s staff (within contractual confidentiality or security constraints) to document the firm’s experiences. We’ll be checking in periodically to see how the transition process unfolds...

While the concepts behind "building information modeling" or BIM have been around for almost two decades—Graphisoft's ArchiCAD solution, for example, was developed on model-based principles from the start—it was exactly 4 years ago when Autodesk embarked on a series of events in major cities across the US, designed to educate its customers about the benefits of the BIM approach embodied in its recently acquired Revit product. I had attended one of these events held in January 2003 in San Francisco. (An article I wrote about that event can be seen here.) Even at that time, the vision of BIM that Autodesk presented was not restricted to the design phase; it was anticipated that the benefits of BIM could extend to the construction, and operation and maintenance phases as well, making BIM the cornerstone of an integrated "building lifecycle management" process...

"Architecture is a strange animal. It's equal parts art, science, and business," says Susan Piedmont-Palladino, a curator at the National Building Museum in Washington, D.C., and editor of the forthcoming book Tools of the Imagination: Drawing Tools and Technologies from the Eighteenth Century to the Present (Princeton Architectural Press). "I was interested in the many stories of invention, how architects are creative tinkerers who borrow tools from other fields—say, astronomy or land surveying in the past to computer programs used to design cars."

The book weaves a narrative of architects' adventures in adopting new tools and techniques, from the folding compass used by Jefferson to Frank Gehry's use of CATIA software, used previously in the automotive industry—and beyond...

Dec. 14, 2006 -- A group of motor-sport professionals can thank computer-aided design software publisher Autodesk Inc. for helping them break the world stock car speed record over Fourth of July weekend in 2006. The team used the San Rafael, Calif.-based company's Inventor 3-D design product during the building process of the Ford Taurus that achieved the record-setting speed of 222.64 mph.

Autodesk's annual user conference, Autodesk University (AU), which is typically held every year in late November or early December, continued with its explosive growth in 2006. Held last week at The Venetian in Las Vegas, the event was packed with 7,500 attendees, a dramatic increase from the 5,000 attendees in 2005. The corresponding numbers were 4,400 in 2004 and 3,300 in 2003, showing that the conference has more than doubled in just 3 years. To better manage the huge turn-out, this year's event was broken down into different "campuses" representing the different industries Autodesk caters to: Building, Manufacturing, Plant, Civil Engineering and Geospatial, and Media and Entertainment. In addition, General Design and Education were also created as separate campuses to better target their specific users. While the differentiation into campuses certainly helped, it was still quite a challenge to navigate the crowds and get around the conference venue to the various events and sessions. If AU continues to grow at this rate, Autodesk might eventually have to host separate user conferences for its different industries! Of the 7,500 attendees this year, close to 2,500 came from the Building industry alone...

Powerful global forces are pushing for faster adoption of building information modeling (BIM). Are you ready?

Client requirements for faster delivery, new standards imposed by the U.S. General Services Administration (GSA), the move toward sustainable buildings, and increasingly competitive global building supply markets have all given design firms impetus to move forward with BIM. There’s no question that the architecture, engineering, and construction firms that adopt a holistic approach to building systems will gain market share.

The promise of bringing sustainable building design and value engineering together can be realized with help from BIM-based technologies. Building projects are complex and, in the past, have gone through a linear, step-by-step process. By sharing a single data model across an entire project team, BIM allows architects and designers to draw on the wealth of knowledge of downstream disciplines, including structural engineering, MEP, and even the construction trades...

Following closely on Microsoft's debut yesterday of the long-awaited Windows Vista, Autodesk announced that DWF technology has been incorporated into the new operating system using XPS (XML paper specification). This will allow Vista users to view DWF files without requiring plug-ins or other additional software tools. DWF files published to the XPS specification can be automatically opened and viewed using the XPS viewer built into Windows Vista, Autodesk reports. We spoke with Amar Hanspal, vice-president, Autodesk Collaboration Solutions, on the general topic of DWF prior to this significant announcement, which we reported initially in yesterday's edition of Cadalyst Daily newsletter...

Though the Autodesk Revit platform for building design is catching on with customers (Revit Building recently passed the 100,000-seat milestone, the company reports), 2D won't be disappearing any time soon. That's the word from Jim Lynch, vice-president of marketing for the Building Solutions division, who spoke with me at Autodesk University 2006, now under way in Las Vegas. Autodesk is in fact promoting a 2D-to-2D transition by encouraging AutoCAD users to move to Architectural Desktop, which it bills as a better AutoCAD for architects...

The 14^th annual Autodesk University kicked off yesterday in Las Vegas, with a reported 7,500 people in attendance -- a number that seems credible given the lunchtime gridlock at the escalators. The event opened with a keynote address by Autodesk president and CEO Carl Bass, his first after taking over from Carol Bartz in May.

Bass said he sees Autodesk's mission as delivering software tools to help people experience something before it's built. Digital prototyping helps customers to better understand, analyze and communicate their designs. Rather than the usual focus on new products and features, yesterday's keynote featured a series of short customer presentations. "In the past few years, we've done all the talking," Bass said. "This year, we'll increase the degree of difficulty and have customers do the live demos."

On Oct 26, the AIA Center for Building Science and Performance (CBSP) organized a one-day Symposium in Washington D.C. to explore and further the use of BIM (building information modeling) technology for designing energy efficient and high performing buildings. One of the most significant aspects of BIM is its ability to capture the description of a building in a semantically intelligent format that can be analyzed to study different aspects of its performance, and with the growing emphasis on green buildings, energy analysis certainly ranks as one of the top-ranked criteria that needs to be studied...

Design-Build Institute of America program showcases BIM for first time ever

DBIA (Design-Build Institute of America) convened its 2006 Professional Design-Build Conference and Expo at the Gaylord Opryland in Nashville, Tennessee, on October 18-20. I was there to make a presentation as well as check on the progress of the design-build approach to architecture and construction and check out some new software products.

DBIA is a professional organization founded in 1993 to advocate and advance single-source project delivery within the design and construction community. Design-build, as defined by DBIA, is a method of project delivery that embraces architecture, engineering and construction services under a single contract, integrating the roles of designer and constructor. DBIA members include practitioners from all project phases, as well as public- and private-sector project owners. Among DBIA's directors are prominent executives within the architecture and construction fields.

Since personal computer technology first became widely available in the early 1980s, followed shortly thereafter by software applications for the building design and construction industry, the real capabilities of that technology have rarely kept pace with the hyperbole that quickly grew around it. At times, the hype has evolved into a belief system bearing little or no relationship to the daily reality of design and construction in architecture, engineering, and construction firms. Early enthusiasts of computer-aided design (CAD) technology may recall discussions or claims related to the “multiplier factor,” in which the value of this or that CAD application was ostensibly measured by whether using it was two, three, or four times faster than manual drafting. As the difficulties of harnessing CAD technology became evident, and the apparent lack of any multiplier benefit became evident, the “multiplier factor” and many other claims related to increased productivity and business process reform were quietly excised from AEC technologists’ vocabulary...
