This posed another challenge as architects required a way to tell the computer what to do that was less tedious than the punch cards that were used on early computers.

Building Information Modeling (BIM) is a term that has become ubiquitous in the design and construction fields over the past 20 years, but where did it come from The story is rich and complex with players from the United States, Western Europe and the Soviet Block competing to create the perfect architectural software solution to disrupt 2-Dimensional CAD workflows.

Building Information Modeling Drivers Of BIM

Save this picture Courtesy of The Business Value of BIM in North America The benefits of an architectural design model tied to a relational database have proven to be incredibly valuable, with contractors becoming the primary drivers of BIM technology for the first time in 2012.

What exactly is BIM The question often arises, for the purposes of this article, BIM software must be capable of representing both the physical and intrinsic properties of a building as an object-oriented model tied to a database.

In addition most BIM software now features rendering engines, an optimized feature specific taxonomy and a programming environment to create model components.

The user can view and interact with the model in three-dimensional views as well as orthographic two-dimensional plan, sections and elevation views of the model.

As the model is developed, all other drawings within the project will be correspondingly adjusted.

A Building Information Model could be designed in a software that is not strictly speaking, parametric and where all information and geometry is explicitly defined but this would be cumbersome.

A parametric building modeler will allow the user to create constraints such as the height of a horizontal level, which can be tied to the height of specified set of walls and adjusted parametrically, creating a dynamic database model which is tied to geometry.

This development answered a need in the architectural industry to be able to change drawings at multiple scales and across fragmented drawing sheets.

The amount of hours that are necessary for the production of drawings has decreased steadily over time with the general trend of non-farm labor in the United States since 1964.

The improvement in productivity has risen in concert with computer technology which has automated tedious tasks in all disciplines.

Although some of the earliest programs for architectural representation used a BIM metaphor, limitations in computer power and awkward user interfaces for BIM platforms contributed to a growth in two-dimensional line drawing programs such as AutoCAD and Bentley Microstation.

The Beginnings The conceptual underpinnings of the BIM system go back to the earliest days of computing.

Englebart gives us an uncanny vision of the future architect in his paper Augmenting Human Intellect.

He examines it, adjusts it These lists grow into an evermore-detailed, interlinked structure, which represents the maturing thought behind the actual design.

Englebart suggests object based design, parametric manipulation and a relational database; dreams that would become reality several years later.

There is a long list of design researchers whose influence is considerable including Herbert Simon, Nicholas Negroponte and Ian McHarg who was developing a parallel track with Geographic Information Systems (GIS).

The work of Christopher Alexander would certainly have had an impact as it influenced an early school of object oriented programming computer scientists with Notes on the Synthesis of Form.

As thoughtful and robust as these systems were, the conceptual frameworks could not be realized without a graphical interface through which to interact with such a Building Model.

The two main methods of displaying and recording shape information that began to appear in the 1970s and 1980s were constructive solid geometry (CSG) and boundary representation (brep).

The CSG system uses a series of primitive shapes that can be either solids or voids, so that the shapes can combine and intersect, subtract or combine to create the appearance of more complex shapes.

This development is especially important in representing architecture as penetrations and subtractions are common procedures in design, (windows, doors).

The process of design requires a visceral connection to the medium that the designer is working in.
