What do you think about modeling in engineering and construction? Models are a natural evolution for us in the digital world. When we first started using CAD, it was not much more than a digital pencil and a digital drafting board. But wow, have we evolved! If you or your engineers are using any of the latest design tools, they are creating 3D models. And depending upon the engineer's sophistication, they may be very information or data robust models. Agencies like Utah Department of Transportation and Federal Highway Administration are leading the charge by bringing models to the forefront of design and construction. We are headed toward models being the legal document or the legal delivery for solicitation and construction. Are we ready? Many states are already moving to approve models as the official engineering document of record. It is happening. So, let’s leave that professional or legal debate to ‘others’ to resolve. What is the impact on bidding, construction, and inspection? 

Let’s look at bidding and solicitation first. One of the few positives that came out of COVID was the acceptance of electronic bidding as not only a norm, but a requirement for most agencies and firms. What does our current construction bid package look like? PDFs of plan drawings, specifications, legal and contractual documents, and survey/geotechnical data. If a model is included, it is for informational purposes and in a vendor proprietary format. And, that model, if properly done, contains mountains of important and influential information about your project. But it is informational only. Can you consume all of the information? Who within your team can digest the information? Today, it takes someone as talented with modeling software as the person who created the models. Does your Bidding and Contract staff have these skills? If so, you are very fortunate. What about your subcontractors? Do they have the skill set necessary to dissect a model using the design modeling tools? In many cases, they may not even have access to the same tools as the model creator. It certainly sounds like I am painting an abysmal picture. But it is not a dark horizon. There is hope, a future, and help is on the way. Two things must occur to provide that digital bridge from design to construction. 

First, we need an industry consolidation on standards that will provide collaboration among vendor proprietary formats. We can all attack vendors about proprietary formats, but vendors should have the right to protect their IP they have heavily invested in. This has two potential solutions. Truly open APIs, which are a long way off, or a performant, robust, neutral data standard. 

Enter Industry Foundation Classes, or IFC. IFC, under the steady guidance and stewardship of buildingSMART International, is an ISO-certified representation of both the geometric model and the business meaning behind the geometry. With IFC, we can represent a road as a road and a bridge as a bridge in ways that any software can understand and make use of. When a vendor is reviewing proposals on Bid Express, Infotech’s online bidding platform, to determine if there are jobs they would like to pursue, they must comb through hundreds and hundreds of item lists and plan sheets. If they are a subcontractor, they might be looking for a single needle in a haystack. What if, instead, they could open the project in a virtual environment, move throughout it, and quickly determine if this type of project is in their wheelhouse? It is just one of the many ways having the model available throughout the entire lifecycle completely changes how people will work.
