## Taking control over the full process

Before this application, Heijmans outsourced the design of wind turbine foundations. Now, with extensive research and the ability to store this knowledge directly in the application, they deliver complete designs themselves. This shift gives them greater control over the entire process.

“Previously, we relied on third parties for wind turbine foundation designs,” Tom notes. “Now, we have all the knowledge in-house, allowing us to communicate faster and avoid rising costs from external consultations. This tool lets us deliver designs much more quickly and efficiently.”

With full control over the process, Heijmans expects to lower costs and improve success rates in tenders.

## Multidisciplinary automation

Heijmans has a history of developing applications to automate and optimize processes for individual departments. However, the Wind Turbine Foundation tool marks a significant shift.

"This project was unlike anything we’d done before," explains Tom Nillesen, Lead Developer of Parametric Design at Heijmans Construction and Geotechnics. "It was our first application that integrated multiple disciplines, making it not only more complex but also much larger."

Heijmans leveraged previously developed logic from earlier applications to build the Wind Turbine tool, which was critical in speeding up the development process. "Reusing code means we don’t have to start from scratch every time," Tom explains. "It saves us time and effort, as we can pull from our Python code library whenever needed."

The Wind Turbine application was Heijmans' first tool designed for use across multiple departments. Wind turbine foundation design requires data from a variety of sources, so Heijmans incorporated input from three departments: Wind Energy, Construction and Geotechnics, and Calculations. The process is complex, starting with the Wind Energy department receiving a tender request. From there, Construction and Geotechnics develops the tender design, which Calculations uses to determine the cost estimate. Once the design is approved, Heijmans oversees the realization of the wind turbine foundation. 

## How the application works

Built on the cloud-based VIKTOR platform, the Wind Turbine tool integrates various calculation software packages, including IDEA StatiCa, SCIA Engineer, and D-Foundations. It handles data from multiple sources, such as soil research, turbine suppliers, and pile types. Here's how the process unfolds:

![wind turbine foundations design automation](https://cms.viktor.ai/uploads/Heijmans_article_img_5c0ad1101c.svg)
 
1. **Input Data:** Information about soil capacity, turbine specifications, and pile types is uploaded and stored within the application. Soil research data is automatically classified, while turbine and pile databases are created for easy access.

2. **Creating a Tender Design:** After all data is uploaded, users can define input parameters like foundation plate size and pile numbers. The tool runs geotechnical calculations via D-Foundations and structural analysis with SCIA Engineer. If the design meets the criteria, a reinforcement design is generated using IDEA StatiCa. Otherwise, adjustments are made, and calculations are re-run.

3. **Cost Calculation:** After completing the calculations, the tool provides specific information to determine the cost of the project.

</br>

Since the Wind Turbine application is multidisciplinary, it allows all relevant departments to access the necessary information. However, to maintain structure, only designers responsible for calculations actively operate the tool, providing key information to other departments as needed.

## Towards a unified system

The Wind Turbine application was built with collaboration between three departments in mind, but Heijmans has aspirations to create an “umbrella application” that integrates even more departments, such as Soil and Roads, into one seamless workflow.

“Our goal is to build a network of applications across the organization, where any change automatically updates related processes. We’ve started small, but with success from projects like the Wind Turbine tool, we’ll continue expanding,” says Tom.

## Automation in the offshore sector

While a lot of automation is already taking place in the automotive and aviation sector, the offshore sector is still lagging behind. According to Maas Hoogeveen, Technology Director at Mocean Offshore and developer of Calypso, this is because the offshore industry is a highly conservative market. “Everybody works on their own projects and has their own reasons for sticking to the old principles. But we are working on applications with automated calculations that will reduce the time and money spent on a project.”

### No more manual tasks

In the jack-up industry, there are still many repetitive tasks performed by engineers. This is partially due to the complexity of the frameworks laid down in ISO 19905. However, it is not commercially viable for the experts to fully perform the extensive calculations manually; they have to use conservative shortcuts. Hoogeveen: “We use algorithms and parametric models, so that shortcuts no longer need to be used and calculations can be done faster and more specific.”

>“The best way to share knowledge is by making it available through a web application.” - Maas Hoogeveen

## Looking for the right digital tools

Maas has spoken with many market parties about making his application available online via a web interface. “It would be a costly enterprise to even create a Minimal Viable Product. Then I came into contact with VIKTOR, which was a great fit. The interface was exactly what I envisioned. It meets the wishes of various stakeholders. A sales manager, for instance, may want to use Calypso as a means of communication with which he or she can generate clear images, whereas an engineer may want to perform in-depth calculations and optimize the use of a platform. Calypso’s interface caters to many different users, which is made possible by the versatility of the powerful VIKTOR platform. Another big advantage is that the costs are much lower.”

> “The web application was developed within 40 hours. The iterations that have been done were also implemented quickly. This offers enormous opportunities because time and budget are the bottleneck.”

## What is Calypso?

### Site-specific assessment

Calypso is a tool for performing site-specific assessments on any jack-up platform. This determines whether you can install wind turbines with a light or a heavy platform. The tool can be used even before you start a tender. Maas Hoogeveen explains: “We specialize in analysis of jack-ups. The knowledge and calculation methods contained in Calypso are an implementation of the jack-up engineering standard ISO 19905-1:2016. With this application, every engineer can perform a site-specific assessment (SSA).”

Check out how you can analyze offshore wind turbine installation platforms without being expert with Calypso and VIKTOR:

<div style="padding:56.25% 0 0 0;position:relative;"><iframe src="https://player.vimeo.com/video/584895866?badge=0&amp;autopause=0&amp;player_id=0&amp;app_id=58479" frameborder="0" allow="autoplay; fullscreen; picture-in-picture" allowfullscreen style="position:absolute;top:0;left:0;width:100%;height:100%;" title="Calypso-Tutorial-Jack-up-SSA"></iframe></div><script src="https://player.vimeo.com/api/player.js"></script>

### Automated calculations

In addition, the calculations are automated, but an engineer can still look deep inside the system to check all steps and calculations. “This is what we call the glass box paradigm, as opposed to the black box”, Hoogeveen explains.

### Capitalizing knowledge and skill

The main objective of Calypso is to capitalize upon knowledge and skills regarding jack-up engineering by making these available to the offshore industry. Running it as a VIKTOR application is a great way to achieve this: “VIKTOR matched perfectly with our vision of what the interface should be. The way parameters are set and how the model is directly visualised is how we imagined it,” Hoogeveen explains. The web-based application can be used independently by clients, so they can make calculations on their own data and problems.

![Web-based VIKTOR Calypso application.png](/uploads/Web_based_VIKTOR_Calypso_application_3bdaa727dc.png)

## Fast development is not impossible!

The development of a web interface to an application doesn’t have to take months, it can be realized in just a week. Maas Hoogeveen: “We developed a headless application, containing the algorithms and parametric models. With this basis and the assistance of VIKTOR developers we build the Calypso application in only 40 hours. The extensive possibilities of the VIKTOR platform are inspiring. With their help, Calypso is as accessible and user-friendly as we imagined.”

The problem with the gravity based foundation (at BAM) was that it was determined or calculated using a number of separate Excel sheets. Among other things, investigation was done on the stability during floating and sinking, the natural frequencies and the strength of the design. You can imagine that this was not done very efficiently.

## The issue of centralization

All members of the project team were working on the same design, but each within their own discipline. So everyone used their own sheets. This caused problems, because if someone changed the input parameters, each team member had to be notified, which would result in everyone updating their own sheets. Making a complete design and calculating all sheets properly therefore took 5 to 10 days. There was this idea that it could be done better, so a tool has been developed to be able to perform these analyses at the same time.

## Bringing it together

For this, all calculations made in Excel have been transferred to an application on the VIKTOR platform. The calculations have been translated into Python code, so some methods had to be changed. The end results have of course remained the same. The advantage of the VIKTOR platform compared to only Python code is the interface (where the input and output parameters are centrally controlled), data management and version control.

This ensures that everyone works with the same input parameters at the same time, without having to manually pass on and adjust them. Everyone is also working on the same version of the design, so no miscommunications or misunderstandings can arise. This is something that can easily happen with separate Excel sheets: several different versions can easily be made.

## More designs, faster!

An analysis now takes a few hours instead of a few days. That is a huge difference, which makes it possible to design faster and make more designs with the same people. A number of designs have already been made, so a new design similar to this is relatively quick. If you make a completely new or large design, it will take a little longer. But is is certainly much quicker to use the application than by the old methods.

This application is made specifically for BAM. It is entirely based on internal documents and tools of BAM. Copying this application to another company is therefore not easy.

![Analysis of gravity-based foundations on the VIKTOR web application](/uploads/gravity_based_foundation_application_59047b4c08.png)

*Analyses of gravity-based foundations in on the VIKTOR web application*

## A building block for future use

What can be re-used is the method used to create the application. Combining different disciplines is a (generic) process, which can be a useful tool for almost all companies. Having separate programs for different parts of a design creates far more misunderstandings than having all data centralized.

## Thus...

In other words, the application for the gravity based foundation ensures that all data is centrally stored and that everyone works with the same version of the design. For example, there are no misunderstandings due to changes in Excel sheets. It is now also easier to make a design together, since the inputs are centrally controlled and everything is done using the same input, so the calculations are more central and clear. “You go from a design in 5 days to a design in 4 hours.”

VINCI used VIKTOR to compute crane foundation designs in just **15 minutes**, a task that typically takes **3 to 5 days**
The automation of crane foundation design calculations is a simple but exhaustive and repetitive process: large amounts of data are required that must all be processed through multiple third-party software packages, such as Excel and Autodesk Robot. At VINCI, they have dozens of engineers that work on designing up to 225 cranes in France every year. Because the design calculations are very similar but specific for every crane each time, this task is very well suited for [automation](https://www.viktor.ai/customer-cases/43/how-vinci-yearly-saves-300-days-calculating-crane-foundation-designs).

## Automating calculations by linking Excel sheets to SCIA

Many Excel sheets are used in construction to do calculations. A lot of time and energy has gone into developing the sheets, especially to get them verified and validated afterwards. Heijmans has linked their Excel sheet with reinforcement calculations for concrete cross-sections to SCIA in an application on the VIKTOR platform for the reinforcement of slabs. For example, fewer numbers now have to be copied, so that one can work more efficiently, and the risk of error is reduced.

## Collecting everything in one place

Roland Snelders has been involved in the development of the concrete slab reinforcement application for Heijmans. “We could read the internal moments from a SCIA file and these were collected in the report, usually in a table. Then those moments could be entered in Excel and the reinforcement was determined and tested in an iterative process. That calculation was therefore copied to the report. ” This way of working could be done more efficiently. It would be easy if copying numbers is no longer necessary, because everything is collected in one place.

### No more copy + paste

That's exactly what the application they created does. Snelders: “From SCIA we can now export an XML file and read it into the application on the VIKTOR platform. The Excel sheet is also linked to this. After selecting the concrete cross-section data and various reinforcement options, I get a picture with colors that indicate where the reinforcement should be.” This ensures that you go directly from the SCIA file with a once-off data entry to a visualisation of the results that come from the Excel sheet, without having to copy anything.

### Centralizing data

The Excel sheet has not been completely transferred into the application, but rather has been linked to it. This has the advantage that it does not have to be recreated, which would then have to be validated. In addition, all manufacturers know how to make a calculation in Excel, you can still continue to do that. “The application ensures that everyone now works with the same Excel sheet, since it can only be opened centrally,” says Snelders. This significantly reduces the risk of errors.

## General use of the application

The application can be used in any construction that contains a slab, for example a floor, a wall, a roof or a bridge. “Initially, only rectangular slabs could be calculated and analysed, which was a major limitation,” says Snelders, “This has now been improved to allow for all types of slab shapes to be calculated.” The application is made by developers of VIKTOR, because Heijmans did not yet have the required knowledge to do it themselves.

![Excel and SCIA connected.png](/uploads/Excel_and_SCIA_connected_c24d123297.png)


## Partial automation for now

This is the beginning in terms of automation. "For the time being it is not going to be possible to calculate entire constructions completely, because there is a lot of variation in every project." Snelders explains, "But it is very useful to have components of that construction automatically calculated." There is less variation in the components themselves, so they can be calculated perfectly with an application. This allows the structural engineer to have more time for the more complex and challenging aspects of his/her work.

## More space left for challenging work

Snelders: “The application makes work more fun. I do not find completing an Excel sheet challenging work. ” When filling in cells and copying data, a structural engineer adds little knowledge to the process. Where they do add knowledge is during the schematisation of the construction and the making of a calculation model, in order to subsequently arrive at an optimal and practical choice of reinforcement. "That work still remains, we have mainly automated the repetitive calculations."

Since the start of the program in 2014, € 100m has been invested in innovations, which has already yielded at least € 180m in savings. “We expect that the new knowledge will yield a multiple of that in savings in the coming years.” Are the savings heading towards € 1 billion? “I would not dare to take on a saving of 1 billion, but it would be inspiring for society if that succeeds.” Because the risk of a dike breach according to safety standards must not be greater than once every five to ten thousand years, until 2050, at least 1,300 kilometres of sea and river dikes and 500 locks, weirs and pumping stations must be strengthened. To this end, a budget of € 7.4 billion has been agreed up to 2028, which must be jointly raised by the central government and the water boards.

## Custom work for dike improvement

One of the promising innovations is using [parametric design for custom dike improvement](https://www.viktor.ai/customer-cases/24/parametric-design-dike-python-D-series-Plaxis-SCIA-Excel-BIM). In other words: not starting from a high water scenario with one water level with different conservative assumptions and factors, as before, but calculating many thousands of scenarios based on an extensive database and the specific characteristics of a dike section. To arrive at the most likely scenario of strength and failure for each stretch of the dike. 


![calculating dike.png](/uploads/calculating_dike_0580c2c558.png)

This customization can mean that in 80% of the cases, the dike improvement job in the Netherlands can be reduced and in 20% of the cases must be enlarged, says Willems. “Much of the dikes can be built slimmer and less high. This means that the balance tends to make the total program cheaper. “That does not mean that the budgeted amount of € 7.4 billion can be reduced. “Even when the agreements for the HWBP were made in 2013-2014, it was clear that the financial agreements were not sufficient,” says Willems. “That was a conscious choice to ensure efficiency in the HWBP utilizing innovation and knowledge development at the front. “Extra jobs are also coming up. “Rijkswaterstaat and the water boards are assessing all dikes. They do this once every twelve years, a kind of periodic MOT. They will be working on that until 2023 when dikes will emerge that need to be strengthened.

## Increasing design efficiency

However, providing an adjusted design after each road or artwork change costs a lot of work. About two years ago, WTOP decided to investigate where most of the time was spent in the process of designing, and where this could be done more efficiently. This showed that in a number of these processes, many hours were spent on repetitive and unimaginative work. In addition, it turned out that arranging and creating a smooth line with these barriers is a complicated process and time-consuming. Jaap van de Werfhorst, owner of WTOP infra, decided that this process should be automated.

## Automating the process

The work of manually placing elements along the road based on a maximum angular rotation and, if it turns out not to fit, to start this process all over again, had to find an alternative solution. WTOP infrastructure was in contact with VIKTOR to see how various processes could be better linked to each other, and the above mentioned problem was discussed with the question wheher using VIKTOR would be fruitful. At VIKTOR they came up with the proposal to do this with a self-written algorithm. Van de Werfhorst: “Initially, there was still uncertainty whether the algorithm could also handle complex projects. If it could carry out the 80% easiest projects, it would not be of much use to us, because it is precisely in the difficult 20% where the most profit lies.”

## An application for complex projects

“After several brainstorming sessions, we were confident that the application could also handle complex projects,” explains Van de Werfhorst. In the application you can define your grid, the bounds of the design, the horizontal and vertical alignment, the maximum angular rotations between the elements, variables related to defining the angular rotations, other constraints such as cables and pipes, artworks, etc. and where you wants to apply your fitting elements. All these parts can be entered in both x, y and z directions. Based on all this input, the algorithm determines the optimal line of the noise barrier. In a visual representation, the application shows by means of colors whether the barrier can be made with the specified conditions. If it turns out that this does not work, the application indicates where the problems are, so that the conditions can be adjusted at those specific locations if desired. This can be done by increasing the angular rotation between the elements, which may then create elements that meet the requirements or by giving the barrier some more space by adjusting the bounds of the design. The great thing is that the program examines and calculates hundreds of thousands of possibilities within a few minutes. The application also generates a list of coordinates in x, y and z direction of the design. This list of coordinates is imported into Excel by WTOP infra, after which all elements that meet the requirements are generated by dynamo and placed in a 3D model. In addition, dynamo in combination with excel creates a quantity list with the main dimensions per element. As a result, the consequences of design choices are immediately visible in both a 3D model and quantities.

## What can be gained? 

Due to this extensive automation, instead of spending much work on unimaginative tasks, the time can now be spent on solving details and interfaces. The advantage is that various choices can be made clear at a detailed level quickly in the tender phase, which also makes it easier to estimate the risks. Since all parts and placements are generated from a single coordinate list, including the production drawings and layout drawings, it is also possible to act quickly during the design process and execution, and failure costs due to changes can be minimized.

Van de Werfhorst: “The step that we have taken together with VIKTOR ensures that we are at the beginning of a development that can be carried out much further by linking this to schedules, cost estimates, etc.” The application and links made with analysis- and drawing programs are useful not only for noise barriers, but also for everything in which prefabricated (3D) elements are placed on or along an alignment, which is currently also being implemented.

For complex projects, it is important to deliver designs in complete 3D, so that they can be incorporated into BIM. But this process takes a lot of time.

## Custom truss constructions

The truss constructions at large music stages become bigger and more complex. Festivals want to have their own unique stage, with a custom truss construction. These constructions are very expensive if they have to be custom made, or you have to deal with a limited set of standard shapes with existing products. 

![Truss construction design in the analyze one](/uploads/Truss_constructions_in_the_analyze_one_3bfe986172.jpg)


### Software and building blocks

FrameFlux is offering an affordable option for creating your custom construction. Yufe Wong, cofounder of Frameflux: “We invented an adjustable, reusable building block, with which you can create any shape structure you want, with the same level of form-freedom as a snake!” Besides the physical product they also developed in-house [parametric design](https://www.viktor.ai/blog/46/parametric-design-cloud-engineering-construction) and analysis software tools to rapidly design these custom shapes and analyse them. “You can perform a structural feasibility check in seconds on an unlimited set of forms, including the conventional shapes.” This removes a barrier to the use of the truss, since it would be difficult to engineer and design some of the complex structural shapes that become feasible.

![Truss construction design](/uploads/Truss_construction_design_56c25ff136.jpg)


## Hitting the market

After demonstrating the software tools to customers and receiving a lot of enthusiasm, FrameFlux wanted to take the next step. After an elaborate vendor selection, FrameFlux partnered with VIKTOR for their experience and integration with Grasshopper and Python, along with a user-friendly interface to suit the needs. Since March 2020, the two companies have been collaborating to deliver this software product, named Antalyze One. This application allows integration with SCAD Re-Event, a popular 3D CAD program for the Dutch event industry. Now a super-fast workflow for design of standard truss beams is realized: users can create a design in SCAD Re-Event, export the data to the web-based VIKTOR platform, and then instantly run a Grasshopper-powered structural feasibility check. It is also possible to make changes in VIKTOR and re-import these back into SCAD Re-Event. VIKTOR’s fine grain data management systems, for user information and technical data, allow for such automation when coupled with Grasshopper. In future, integrations with other CAD programs will be possible.

## A user-friendly interface

“With VIKTOR we’ve got a friendly user interface and a good integration with our existing Grasshopper model, instead of starting over again.” In the web-application an event designer can also upload their design and other relevant inputs whenever and wherever they want. As before, this information is sent to the Grasshopper model in which the analysis is done. The results of this analyses are sent back to the web-application and visualized for the event designer.

![Visualizations of truss construction designs](/uploads/Truss_construction_visualizations_deb241cb3c.jpg)


## The 'Antalyze Two'?
The decision to automate this process is an easy one according to Yufe “A designer can now create, develop and get a structural feasibility check on their preliminary designs of loaded straight beams without hours of spreadsheet work or consultation.” There are already plans for a potential ‘Antalyze Two’, which will be able to process a much greater variety of structural shapes. “Especially for custom-made constructions it could take weeks before a design was analysed by a consultant. With our software and the web-application made on the VIKTOR platform, a check could be run on squares, circles and snake-like structures… in only a matter of seconds!”

## Designing a sustainable future

Stefan Schoenmakers, design leader Civil Realisation Substructure of the Theemsweg route at Wagemaker explains that the Calandbrug will have reached its technical lifespan in 10 years. It was built around 1970 and provides road and freight traffic. By removing freight traffic, the lifespan is extended and at the same time the with new rail viaduct, the train traffic does not experience interference of opening and closing the bridge for shipping. The new route is designed for the next 100 years. “We have to look and think far ahead, because mobility issues may change over this period of time. This makes it a very interesting project”.

## Many parts to a mega project

Wagemaker designs almost all the foundations for this project. Wagemaker is part of SaVe, a construction consortium consisting of Besix, Dura Vermeer and Mobilis that is responsible for the design and realisation. “We work with a design team of 12 people at Wagemaker, where my job as design manager is to ensure that our product, drawings and calculations are finished on time and distributed within the organisation of SaVe. We look at implementation, manufacturability, optimisations, alignments with the road design team, with provisions for lighting, making certain parts prefab, and much more. Our constructors and modellers work on all these things simultaneously”, says Schoenmakers. A mega project.

## Complexity and diversity

Not only the size is a challenge; the route is 4 km in length, but also the complexity. “You come across different types of soil situations. In some places the foundation is in water, in other places you have to build across an existing lock, or you have to deal with a very poor soil structure, or a soil structure in which inserting piles is a challenge. It is very diverse.”, says Schoenmakers. In addition, we are dealing with the fact that almost every location is very specific regarding the number of cables and pipes in the ground. Wagemaker looked for an effective way of analysing the foundation supports. “In principle we have 100 support points, some of which are identical, but the situation is different due to the soil composition. Initially, we wanted to make a certain design choice based on a comparison between support points that are similar and then calculate only one”, which is not optimal. Due to previous collaboration on another project, they ended up at VIKTOR. “We worked on the TenneT project, of Heijmans. You were involved in that project as well, and we then saw what was possible and we also want to stimulate development. So we said right away, we are going to do it together with VIKTOR!”.

## The role of the VIKTOR platform

With VIKTOR, the substructure of the route has been parametrically designed and calculated. This was done, among other things, by means of integrations with geotechnical and structural calculation software such as the finite element program SCIA. Schoenmakers: “By using your tool, we were able to generate parametric models with corresponding load cases for all supports and foundations. This made it easy to analyse internal force distributions, pile reactions and other calculation results. We ultimately opted for 5 to 6 basic foundations. They were all defined in the database of the tool and we could attach foundation characteristics, such as soil properties. Actually, this is in reverse order to the normal process, enabling us to much better determine where optimisations are present”.

Using the tool resulted in making the design process and reporting more efficient. The VIKTOR platform has been very valuable not only in the field of calculations, but also towards the client and testing authorities: “This has enabled us to demonstrate that we have been able to design and analyse all support points properly,” says Schoenmakers.

## Wagemaker focuses on digitisation

Wagemaker clearly focuses on the digitisation of engineering; A few years ago, a Virtual Design department was established to keep up with the developments. Of the 8 people there are 2 dedicated programmers employed. “If we can save time on projects by doing things [smarter](https://www.viktor.ai/blog/40/artificial-intelligence-machine-learning-engineering-construction), we have more time for complex projects where we cannot automate or parametrise anything. You became an engineer for the complex thinking involved, thereby empowering people. You don’t want to do the same thing 10 times. It may be nice the first time, and second time as well, but then it stops. It is very time consuming and if you have to do the same thing 10 times over, the chance of errors will also increase”. VIKTOR has provided a clear solution for this. Wagemaker recently participated in a few technical sessions at VIKTOR, in which three engineers are now learning to develop their own tool in the VIKTOR platform. Not participating in this development is not an option for Wagemaker. “We try to stay ahead, because the moment you can do something that someone else cannot do, it strengthens our market position.”

## Why Dynamo?

People from different disciplines use all kinds of different software programs. Where structural designers make extensive use of BIM and CAD software, such as Autodesk Revit and AutoCAD, road designers use Autodesk Civil3D and Bentley MX Road. The skilled designers amongst us automate their workflows in these packages using Dynamo: By creating Dynamo scripts, manual actions can be automated in structural design software, which saves designers lots of time.

Dura Vermeer’s engineers and technical modellers are among these skilled engineers who are highly acquainted with those software packages and use Dynamo intensively in their design process. Their experience, expertise, and the concept of visual programming enable them to quickly develop models with Dynamo. However, some needs are yet to be covered: The exchange of data and versioning of that data remains challenging.

## Why VIKTOR?

Also, although Dynamo is a convenient tool, it has a learning curve: Often only a specialist knows how it works, making other disciplines dependent on the time and resources of these specialized individuals. That’s where VIKTOR comes into play. VIKTOR is a web application development platform for engineers and has a large variety of digital building blocks (like digital LEGO), such as integrations with structural design software. VIKTOR’s web applications provide a central database with version control on the data and offer an intuitive user interface where other disciplines can easily use encapsulated expert knowledge. This is also known as: Democratization of Knowledge.

But the question remains: How do you leverage Dura Vermeer’s existing expertise in Dynamo and VIKTOR’s distribution and data control? The answer: By building an integration between the two! VIKTOR and Dura Vermeer collaborated and developed a Dynamo-VIKTOR node package: Nodes where data can be fetched and pushed from Dynamo to VIKTOR.

## Single Source of Truth

In Dura Vermeer's current design process, the exchange of parameters between the different disciplines often takes place via mail or quick hand-drawn sketches. However, this is not foolproof and can become increasingly risky when many versions and alterations are made. By developing a VIKTOR web application that automatically integrates with different design software, Dura Vermeer no longer requires manual output exchanges. Of course, active communication between the different professionals is still needed, but less normative.

### Creating Dynamo scripts

The Dynamo-VIKTOR node package consists of several nodes (in Dynamo terms, a node is a visual representation of methods/functions with only input and output). When properly placed, the nodes can perform a task such as establishing a connection between Dynamo and VIKTOR. The following figure shows a representation that makes it possible to acquire the input parameters of an entity from VIKTOR to Dynamo. Other configurations of these nodes can create alternative tasks, such as getting results, getting files and even pushing data to VIKTOR.

![The Dynamo-VIKTOR node package](/uploads/Dynamo_VIKTOR_node_package_3359b129c6.png)

By connecting these strings of nodes to other Dynamo nodes, actions and even designs can be automated using the design software. This series of nodes is called a Dynamo script. Once the script is executed, multiple tasks that can be used in Revit will be performed. Since Dynamo is not only supported in Revit, scripts can also be developed for AutoCAD, Civil 3D, Inventor, etc.

### Using the Dynamo-VIKTOR node package

The video shows the same Dynamo-VIKTOR node package used in both Revit and Civil 3D. The video shows how the cross-section is manipulated using the parameters given in VIKTOR. No external exchange file is necessary, resulting in a live connection between all disciplines (in this case the structural engineer, road designer and structural modeller) which is practising the single source of truth principle.

## Connecting software and knowledge

The collaboration between VIKTOR and Dura Vermeer has made a huge difference regarding the way software is deployed. Not only are software packages connected, but also the knowledge of the professionals. Both parties ended up speaking the same digital language, even though their knowledge backgrounds were so different.

In only one sprint (a two-week development period) the live connection between VIKTOR and the structural design software was explored and finally established. Further development will most likely yield many more functionalities and applications, as all kinds of design software can tap into this single source of truth.

## A reusable package for future automation efforts

The Dynamo-VIKTOR node package is a very general utility to exchange data between VIKTOR and Dynamo. It can be linked to any VIKTOR app for which credentials are available and any Dynamo script. That is why this is a digital building block that Dura Vermeer can reuse in their future automation efforts as well. In the long term, VIKTOR can continue to provide digital building blocks that Dura Vermeer can use to realize their vision of becoming the best digital contractor in the Netherlands.
