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.

## 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).

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.

## Centralized data for gravity-based foundation analysis

BAM automates the design of gravity-based foundations from  **5 days to just 4 hour .**  The gravity-based foundation is a concrete platform on the seabed (approximately 30 meters in diameter) which is used for wind turbine foundations. The problem with the gravity based foundation 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 by different disciplines, each using their own Excel sheet. [This meant that making a complete design took 5 up to 10 days.](https://www.viktor.ai/customer-cases/21/web-application-Excel-python-gravity-based-foundationsThis) 
Then, the calculations made in Excel where transferred to a VIKTOR web app that 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.

## 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."

## Strengthening the pumping stations

The HWBP is a joint investment program of Rijkswaterstaat and the water boards, who are in charge of flood protection infrastructure in The Netherlands. 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.

## Dike design tool Wilma: a new, digital way of designing

The Wilma dike design tool, created on the VIKTOR platform, is a renewed design environment for the geotechnical consultant. The tool was developed by the Graaf Reinaldalliantie to be used on the Gorinchem-Waardenburg (GoWa) dike reinforcement project.

The innovation consists of the combination of cleverness and insights of the designer and the infinite computing power of the computer on the VIKTOR platform. For the Wilma tool, design software for the various design mechanisms (D-series and PLAXIS) is integrally linked and data is centrally managed in accordance with the BIM philosophy. Because of this, changes in starting points or other information can be made transparant very quickly, allowing the design to adapt quickly as well. This provides a certain flexibility in the design process that has proven itself to be very beneficial within this project. 

## A challenging reinforcement

The Graaf Reinaldalliantie was established to strengthen the river dike between Gorinchem and Waardenburg. The alliance consists of the Water Board Rivierland and the contractor consortium ‘Waalensemble’ consisting of Heijmans, GMB and de Vries & van de Wiel. Royal HaskoningDHV is associated with the alliance as an advisory party as well. 

This dike improvement project is approximately 23 kilometers long and is particularly complex in terms of tasks related to reinforcement. Not least because of the highly heterogeneous soil structure, which was created in the past on the north side of the Waal by the many old river channels and fillings, the diversity of soil layers and the filling in at the site of old dike breaches. The dike body itself also varies in structure due to the construction of the dike over the centuries and the reinforcements and relocations of the past decades. In order for this dike section to meet current safety standards, several improvement measures are needed that, together with the built environment, the soil conditions, and the transition to undrained modeling, make it a very challenging project.

## Taking initiative

In the tendering phase of the Gorinchem-Waardenburg dike reinforcement project, Waalensemble took the initiative to perform the design calculations in a smarter, more efficient way, based on the positive experiences from previous Heijmans projects (Wilhelminakanaal, Wintrack) where repetitive design issues in particular were efficiently automated. In these examples, design software (D-Series, SCIA, Excel) is linked by means of assumptions and existing equations, resulting in an automated process. This principle has been adopted by the Gorinchem-Waardenburg dike improvement project, further elaborated and further professionalised through the availability of the VIKTOR platform, among other things. The Viktor platform makes it possible to link design software in a much easier way and with extra functionality than was previously possible in the aforementioned Heijmans projects. During the project, the functionality of the dike design tool was expanded in various versions with settlement and failure mechanisms such as macro stability, piping and overtopping, which can be calculated simultaneously per cross section, for both embankments and dike relocations. An example of a schematic of a profile is shown in the picture below.

![An example of a cross section schematized by Wilma with a crown displacement and inward embankment in a D-GeoStability calculation.](/uploads/Cross_section_schematized_by_Wilma_8ed53a86da.png)

*An example of a cross section schematized by Wilma with a crown displacement and inward embankment in a D-GeoStability calculation.*

### The first development

The first development motif arises from the request to support the designer in achieving a higher quality of the stability calculations. The application of the undrained CSSM model requires a schematisation with boundary tensions and a course of the effective tension due to changed water levels and previous loads. Within the functionality of the then available D-GeoStability version 18, this required a far-reaching division of the soil layers with additional stress calculations by the designer. The first version of Wilma has been developed to achieve an accurate calculation of the stresses and to develop an efficient method to include these results in the D-GeoStability model.

### The second development

After a successful application of the first version, the second development started almost immediately. The functionality has been extended to centrally manage the input and output of the various design software. This is in line with the BIM method for quality assurance and version management. In a design analysis, the geotechnical properties per soil layer and the derived parameters that are determined by means of a calculation method, always originate from Wilma and are independent of other design calculations. The old and the new process diagram, where the [parametric design tool](https://www.viktor.ai/blog/46/parametric-design-cloud-engineering-construction) is central, is shown here:

![Traditional vs Parametric vs Generative designwilma design process (1).svg](https://cms.viktor.ai/uploads/Traditional_vs_Parametric_vs_Generative_designwilma_design_process_1_dcdd3d64a0.svg)

*Traditional design process versus new design process with Wilma.*

From this central position, Wilma compiles the input files and sends them to the existing design software, such as the D-series or Plaxis. The results from the design software are then collected and presented via the [parametric design tool](https://www.viktor.ai/blog/46/parametric-design-cloud-engineering-construction). By automating the data flow in the design process, the effort for the designer has shifted from drawing up calculation files to supervising the quality assurance of the calculations and assessing the results.

[![CTA_start_using_PD](https://cms.viktor.ai/uploads/solutions_page_banner_4_f474c9c318.svg)](https://www.viktor.ai/blog/46/parametric-design-cloud-engineering-construction)


## A new design methodology
The greatest gains, however, come from a different design method. The traditional design method is based on the manual input of cross sections by a consultant, which forces planning to make choices about how many cross sections can be calculated. In a complex project such as this dike improvement, this quickly means that major simplifications are needed to realise a design within time and money. One calculation that is normative for hundreds of meters of dike is common. As a result, the design is over-dimensioned, which in principle is not wrong from a safety point of view, but does lead to strict and heavy measures that affect the environment and are therefore not always desirable from stakeholders.

### An automated way
A new automated way of calculating means that it will be possible to calculate a very large number of cross sections, instead of one standard profile. In theory, a transverse profile can be calculated with possible variants for each dike stretch where a different situation arises. This is shown schematically in figure 3, where each block represents a new situation.

![The schematic choice for a standard profile (red) or several representative profiles (yellow)](/uploads/the_schematic_choice_for_a_standard_profile_red_or_several_representative_profiles_yellow_1acc3b2033.png)

*The schematic choice for a standard profile (red) or several representative profiles (yellow)*

The ability to design a large number of profiles provides the following benefits:

1. The consultant needs considerably less time to calculate cross sections, which means more time for interpreting and analysing results and translating them into the design. This leads to great efficiency.
2. There is the possibility to perform sensitivity analyses in a simple manner with all kinds of starting points, so that a better insight is obtained which parameter influences the calculation result. This makes it possible to conduct targeted additional research quickly.
3. The calculations were adapted and carried out very quickly. While changes in the traditional design process can have major consequences for the interfaces of the design, this is no longer a problem due to all the connections built up in Wilma. Adjustments to the design or starting points can now be directly calculated for the entire route.

### Qualitatively better design
All this results in a qualitatively better design, whereby freedom is created in choosing a design solution based on the calculation results. It is therefore no longer necessary to funnel the output data in advance to compose a benchmark profile, because making the assessment is more extensive than designing an additional profile. In addition, the thinking for weighing up the various possible normative aspects is retained in the result of an additional design profile. The figure below shows this as an example through sketches and illustrations, in which the dike sections are the product of a normative cross section and the white line represents a possible design profile that, as is to be expected, more closely follows the soil structure found. Because the design profile of the white line has actually been calculated, it is possible to choose a more average design profile that fits better in the landscape. The robustness of the design is known at that time.

### Inclusion of additional soil research
An additional positive effect is that carrying out additional soil research now pays off because it can be processed more easily in the built-up subsurface model. With the traditional design method, additional soil investigation is often intended as a risk mitigation to verify the subsurface model. This advantage remains, however, with the design method with Wilma, the additional research is immediately included in the calculations and the design is adjusted.

## Quality assurance

### Processing results
Quality assurance of the design calculations is not formally included in Wilma. The role of the parametric design tool is to compile and start the calculations and to process the results. These design calculations are always performed with the original (and therefore validated) design software. For example, a stability calculation is performed in D-GeoStability, after which the files are also available, in such a way that it looks like a colleague has supplied the calculations. Each calculation is delivered separately from the tool and manually checked by the designer. This workflow of the calculation files also makes it possible to deliver and view the design without having Wilma.

### Centralized storage
The quality assurance of the design calculations has deliberately been left with the designer. However, the parametric design tool makes it easier for the designer to perform the checks. Firstly, because the process of illustrating through schematics, calculating and checking is almost continuous because the lead time for a design calculation is next to nothing. In addition, Wilma can compile overviews of the required control points. All basic principles and relationships important for the design can be checked because the results are stored centrally and are available to everyone.

An example of a simple check is a graphical representation of the stresses in the soil layers or the assignment of the rise height to soil layers. Such a control screen is shown in figure 5. The calculated values ​​are presented for each black-marked point in the design profile. The applied calculation values ​​can be checked at a glance because the assumptions and equations have been consistently and unambiguously applied by Wilma on the basis of the predefined protocol. There are no quality differences due to the preparation of cross sections by several consultants.

![Customer_case_calculations_with_cloud_computing_5](https://cms.viktor.ai/uploads/A_control_screen_in_Wilma_for_the_determination_of_the_boundary_voltages_7a07277148.png)


### Background testing
In order to properly verify Wilma’s work processes, various tests have been built into the Viktor platform during the development of the tool. This checks in the background whether the routines carried out by Wilma always run in accordance with the geotechnical specification. These tests roughly consist of three categories:

1. Rules of thumb; the obvious design rules are checked. Because Wilma applies standard rules, contradictions can arise, as a result of which the schematization steps are correct in accordance with the “design rules”, but the schematization as a whole is geotechnically incorrect. An example of such a test is the descending height to the hinterland.
2. Realistic modeling with fully elaborated schematics of calculations and links. When going through these tests, the routines must always give the same results.
3. Edge cases with exceptional cases to test the routines of the schematisation. During these tests, unrealistic situations are presented from a geotechnical and hydraulic engineering point of view. This ensures that the routines and rules of thumb are robust and that new exceptions are noticed.

By continuously testing with both realistic modeling that is expected within the project, and with edge cases, the behavior of the tool becomes predictable, so that the quality control focuses on exceptions. These exceptions in turn complement the design routines. The systematic elaboration of these exceptions in a design rule results in a more substantiated design methodology and the percentage of exceptional cases is further reduced. This continuous development of the parametric design tool with the insertion of exceptional cases has resulted in the design capacity increasing quadratically. This increase is based on the difference between the number of design profiles per consultant in the exploration phase and the plan elaboration phase.

## The next step
The tool is currently being further developed for more geotechnical functionalities and applications throughout the design process. The possible future expansion of the functionality of the tool can be sought in expanding the tool in the field of computing in the cloud, but also in adding IoT data from sensor technology in dikes. Both seem far away for now, but will sooner or later enrich the world of the civil industry.

Heijmans: “The luxury of having a tool that takes over 80% of the work, quickly becomes your standard”

Dike design automation tool leads to better solutions

## The old method: expensive and unideal 

The current process is often still based on experience and reasoning. Solutions that have proven themselves in previous projects are often chosen; the solutions for the critical sections are extrapolated. That makes sense. Calculating a section takes a lot of time. However, this method lacks a numerical substantiation for the chosen solution. Real insight into the ideal design is lacking and that can cost a lot of money. The gross extrapolation can result in surplus work and material costs, as well as lead to incorrect assumptions and increasing failure costs.

### Cost optimization through parameterization

It is therefore better to find an optimum with global parameters, such as costs. To determine the approach of solving the problem, an application is needed that can vary parameters on an interdisciplinary level, based on pile types, number of piles, pile lengths versus applied reinforcement, floor thickness, and so on. By linking the structural and geotechnical models to the cost model and combining all these parameters, the cost optimum can be found. A user can then determine the domains within which the application can independently vary these parameters and on the basis of which outcome optima must be found (think of costs, planning or risks). Because there are often several options close to each other, a user can also generate multiple optimized versions and weigh them up.

## Creating an application for parameterization

### Application development

The tuning of parameters and the definition of the process were the starting point for the engineers of Lievense and developers of MOCS. Lievense is involved as an expert and user, while MOCS makes the web-based parametric model and ensures that the process is automated to the right level. Three areas of expertise have been brought together from Lievense: structural, geotechnical and cost-technical. In this way, a multidisciplinary optimization can be performed.

### Application workflow

Within the online application, the user specifies per project the pile types available with the different unit prices. The projects can then be designed within a project. For a design section, a user can upload the GEF files associated with the probes created within a section (GEF is a standardized exchange format for the storage and transfer of geotechnical data). The applications provides a suggestion for a soil layout interpretation, which a geotechnical consultant can adapt.

### Modelling

The modeling of a section starts with a global SCIA model without piles. This prevents manual input of data that is already fixed and that is already available in another source. This SCIA file is uploaded by the user via drag & drop. In VIKTOR, the user can design a pile plan in two ways. “Simple”: the user gives a desired number of posts in the x and y directions. “Detailed”: the user can add rows / columns of piles, centre-to-centre distance from the previous row / column. Other parameters that the structural engineer can manage include reinforcement covers, concrete strength classes, and other design choices.

### Multidisciplinary calculations

It is possible to calculate the specified situation automatically in its entirety with a click of a button. All programs (in this case SCIA, D-Foundations and multiple Excel sheets) are run in the background and no human actions are required to perform the entire multidisciplinary calculation. The load capacity of the pile configuration follows from D-foundations and the required load capacity from SCIA. The section forces are also read from SCIA by the VIKTOR application. Via a linked Excel sheet, VIKTOR can convert this into a required amount of reinforcement. All calculated properties together determine the cost of a design. The results of all calculations are displayed in VIKTOR.

## The results are clear!

Since this part of the process is now fully automated, VIKTOR can also generate and calculate a large number of different pile plans. Because all parameters influence each other, it is not always clear which choice is ultimately the cheapest. Lievense is mainly interested in the mutual connections. These are plotted in VIKTOR in an overview. This allows the manufacturer to make solid choices with the help of his knowledge and expertise. As a control functionality and to keep a good overview of the generated designs, Lievense can download files from created D-foundations and SCIA analyses and view them “locally”.

## The final outcome

Only two sprints were needed to develop the full application. Primarily, the result is insight into the influence of the different parameters, the sensitivity of the parameters to each other and an “optimal” solution direction. It is possible to consider more variants in a shorter period of time compared to before, which provides the numerical substantiation of the chosen “optimal” solution. This can bring a lot of value. Initially in money, but with other models this could also be in terms of risks, construction time, feasibility or other KPIs

## 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.

![Data mangement systems for truss constructions](/uploads/Data_management_system_8043c8a027.png)


## 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.”

## 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.”
