Building Information Modeling (BIM)
The new kid on the block will change us.
What is BIM? Why is it necessary? Is it the next big thing?
BIM will grow – it will enable us to create drawings faster and allow us to embed our brand; it has the potential to expand significantly. It’s a concept that will open our eyes to an entirely new way of creating engineering models with an entirely new approach to data use. How will this change our lives? It will reduce time to market, increase accuracy and increase our confidence in the associated data.
A BIM model is a combination of 3D model and associated data. It’s a visualization tool resident on a desktop computer, or on the cloud; a digital twin of the real life project. BIM comes from the recognition that an engineering model is made up of the parts. As 3D Modelers we don’t draw; we assemble parts. The parts themselves are either sold to us by suppliers or we model them ourselves before we build our final assembly. Our engineering or architectural model then becomes an assembly of 3D sub-assemblies with levels of information and detail which was never possible in 2D. When we compile the information about the parts with the model, we have a visualization tool, and a detailed bill of materials for every sub-assembly.
The airport operator can open the file for the main terminal building and hover over the escalator to determine who supplied it, when it was delivered, and how much it cost. Even better; the operator can identify a spare part on the model. The BIM model holds the naming and numbering of spare parts and where they go.
Imagine if Owners, Engineers and Equipment Suppliers on a project could share equipment information on a common platform; making use of the power of visualization and data access on a 3D Model. Currently, draughtsmen use selected information in their models and discard non-relevant data because there is nowhere to store the data in the current model.
Imagine if we could retain core data and hand it on all the way through the process so that the Project Engineer buys the part to the original quotation, and passes on this information to the client so that a spare part can be bought to the same specification, or a modification can be designed using the correct interfaces.
Why build and rebuild when you can create an exact replica and re-use that model again in another drawing? Better yet; what if you could use BIM files to embed brand identification right through the design, manufacture and operations cycle.
Users have the BIM model as a visualization tool to understand supplier interfaces and part dependencies, quantities, access, track schedule adherence and to plan alternative installation sequences, access routes and cranage requirements. Part attributes such as mass, dimensions, lifting points, installation, orientation and location are all available. We now have a tool which allows all tiers of management, operations and support access to data at a new level right through the life of the part.
ParaMatic is developing ways to increase the utility and power of the Digital Twin. While BIM is clearly the future; BIM is slow to gain a toehold yet because of the expense of generating a truly accurate digital twin, the replica of the project. We are excited to share that ParaMatic Piping and ParaMatic Library are first steps in developing a suite of modelling products which facilitate the generation of the Digital Twin.
BIM is in its infancy and will grow. One day a client engineer will order a spare part by scanning a bar code on the original part and a quote carrying shelf inventory, price and delivery schedule of the spare part will be forwarded by the supplier, automatically. It’s clear that it will one day be integrated in the way that we engineer and record.
How the De Hoop Trail Path was built
and how the process will change the future of engineering.
What will you do to upgrade your engineering process?
- Scanning the face of the De Hoop helped us to more efficiently design the stairway and helped us to save money by saving time. Where in a usual scenario one might spend time working and re-working an idea or a concept, ParaMatic’s processes, 3D laser scanning, and piping program all help us, as engineers, to draw once.
- What does draw once mean?
- Draw once simplifies our lives and allows us to get the product to market much faster than a traditional engineer might budget time for. Below we have summarized 10 ways in which draw once helped us to engineer the De Hoop hiking trail, and how this process could change the future of engineering.
- The Engineers from DPW engineering wanted a low profile, aesthetically pleasing, transportable construction for the De Hoop path. We managed to achieve this in a much more time efficient manner than previously would have been possible.
- ParaMatic’s scanning and revolutionary approach towards the applications of 3D scanning and BIM library allowed us to effortlessly create a digital twin of the De Hoop mountainside face, engineer a path to its contours, and draw the pathway once.
- We use the concept of the digital twin to help us.
- The digital twin is a concept that means that we provide an accurate model that is within 1mm of what will be or what has been built in real life. This is a revolutionary concept for engineers, as previously much measurement and approximation has been subject to drawing and redrawing.
- With this digital twin we were able to eliminate errors and re-work on site. The presence of a digital twin makes it much easier and more efficient to analyse data and faults in the building.
- The application of the digital twin allows us to draw once!
- Without scanning, the measurement and approximation would have taken two days if not more, and would have been done with a tape measure. We may have had to return to the site to re-check measurements.
- With ParaMatic’s scanning process we managed to scan the site within half a day!
- The equipment and the path had to be carried for the last 1km, so tools used needed to be minimal – we could budget that into the design without compromising on accuracy. No last minute tools were needed.
- We needed to eliminate welding on site because of sea breeze and corrosion. Having a digital twin present helped us to consider the different facts, options, and possibilities to replace welding. No re-work would be needed on site as we had access to the full portfolio of assets. In a traditional build, last-minute welding may have been necessary… but no longer!
- Engineering is about delivering on client needs and maximising on efficiency. How might having built the De Hoop Trail path help our process in the future?
- “One of the advantages of 3d modeling and digital twin is that it is a nicer format for clients to check that you’ve delivered what they want. What our aim always is and has been is to create a precise 3D model.” – Bruce Martinson, technical specialist.
- We are building up a library of detail assets and processes of building them which comprises of all the particular components they are made with. Ideally a computer would be able to make all these repeatable decisions in order to focus time on what really matters.
- The future of engineering is to enable a single person to be more productive. We allow today’s engineer to survive the decreased time needed from concept to market.
Digital Future
ParaMatic is working for the future. Industry 4.0 will leave those who hang onto their habits behind, and we wish to project our customers into the future. One of those ways is by upgrading the ways in which we work with 3D modelling and BIM.
BIM – Building Information Model – should help us to Engineer Once. Currently engineers generally use an approximation of the final model which will be built, leaving us to modify buildings later, cutting into the buildings and randomly assigning pipes after the building has been built. This costs us time, and it costs us money. Not only does it do this, but it has us visiting and revisiting problems which we should need to solve only once.
BIM models will one day allow us to Engineer Once, capturing engineering data from every decision and selection in the original model. If we park a decision by placing a dummy model in the BIM model, then we must be able to replace the dummy with fast and easy updates, all the while improving the overall model without losing integrity.
ParaMatic invites you to explore the opportunities that automation brings us.
Old and new; where restoration deviates from replication.
How 3D software can help us.
Some might think that the Notre Dame would look the same when rebuilt after the devastating fire; but architects from around the world are suggesting that Notre Dame be reconstructed with modern elements.
3D scanning will help us to fit together the new ideas with the old ideas.
We have plenty of photographs of the outside and possibly a lot of the inside of Notre Dame; however, It is unlikely most of the photographers pointed their cameras at the bits that burnt, the timber structures high above them. There are no drawings or design and the artisans who built it have gone.
Artisans in the past age built gargoyles from knowledge alone, and the only way they’d build a new gargoyle would be from scanning it.
What would you use to rebuild if you hadn’t scanned it? It is difficult to reconstruct without photographs of the seminal information that held Notre Dame together. It’s impossible to call in the photographers of the world because the boring nuts and bolts of Notre Dame would not have been documented.
Notre Dame was built primarily with timber, masonry and ironmongery as engineering materials; using hand cut stone and timber with hand forged nails, and screws and bolts for fastenings of the finer details. The tools we use to construct buildings today are fundamentally different; there is no way that we can truly reconstruct Notre Dame in the way that it was originally built.
With scanning we have a virtual replica of the building in 3 Dimensions, whatever we can see with a scanner we can record, trace and reconstruct. We can measure the thickness and see the connection of a rafter at the ridge beam. We can record and carry out construction and design rules, We can work to accuracies of a few millimetres.
We are moving into a world where the world can be seen in 3D. A digital twin is almost as close as possible to the original. The thing you want to build can be identical to the thing that you are going to build.
