Building Smarter, Faster, and Better: Unravel BIM's Breakthrough at the Paris Basket Arena

GILLES VERSCHAE: Hello, everyone, and welcome for this session about building smarter, faster, and better, the story of the Paris Basket arena.

EMMANUEL DI GIACOMO: Hello, everyone. My name is Emmanuel Di Giacomo. I'm a global business development for the AEC market in Europe working for Autodesk for more than 22 years now. I'm an architect. I've been in the AEC industry for more than 34 years. And I'm also the creator of two Revit Utopic Cities and a famous blog in Europe called the ABCD blog. Have been also leading the Notre-Dame reconstruction project BIM development for several years.

ESTELLE JOULIE: Hello, everyone. I am Estelle Joullié, methods/pre-construction manager for Bouygues Bátiment. I was the head of the method team for the Adidas Arena project for the Paris 2024 Games.

GILLES VERSCHAE: Hello, everyone. I'm Gilles Verschae, head of BIM at Bougyues Bátiment France, a subsidiary of Bouygues Construction. Bouygues Construction is the third largest international contractor, according to the 2023 ENR 250 Ranking. Estelle and I are part of Bouygues, a diversified French group. Bouygues had a 56 billion euros turnover in 2023.

Our construction division represents 9.8 billion in sales, and our company has a headcount of 32,500 employees worldwide. The French building division of the company generated a 3.9 billion euros turnover through 450 ongoing construction sites. We have a headcount of about 8,000 employees, of which 1,200 work in the engineering department.

EMMANUEL DI GIACOMO: Before entering into the technical details of the construction of this amazing building, let's dive into the architectural story of this jewel. Let's admire together this amazing photo showing how this elegant and unique building, pure and simple, getting a seamless integration with its local environment.

Carbon sobriety is reflected in the choice of the energy mix. The arena houses a district cooling plant using geothermal energy locally. This installation will ensure that all of the arena's cooling and heating needs are met in the short term by recovering the so-called fatal heat from this installation, meaning 100% use of renewable and recovered energy for the arena. This new generation equipment will, therefore, achieve unprecedented energy performances, consuming three times less than a conventional arena.

So let's look at this architectural project, which is made up of three elements. First, a largely glazed base open to the district accommodates programs linked to the public spaces, such as local public facilities or the main reception space of the large hall. Here, you can see the base overflowing onto the exterior forecourt to form a true Parisian city level. This south entrance with a joyful lightning atmosphere looks like a cinematographic ambience like in some Asian movies.

Then, at 11.50 meters high, a vast green terrace surrounded by a communicating strip overhanging this base offers nearly 3000m of outdoor relaxation spaces with a panoramic view of Paris. Finally, several distinct shapes emerge from this terrace, symbolizing the different programs hosted, including the 360-degree arena main central shape made of light colored recycled aluminum, representing the project's true signature. Its modularity makes it possible to meet high standards in hosting sporting and cultural events. And it provides a response adapted to each audience with shared spaces accessible to all, like the large peripheral terrace.

Here, you can see the variety of stakeholders involved in this very important project with the city of Paris and the Paris and Métropole Urban Development owners, followed by the two architectural practices, Scau and NP2F, in Europe, the famous French engineering company, Bollinger and Grohmann, engineers of the project shell, and last but not least, the amazing Bouygues Group, including Bouygues Bátiment De France and Bouygues Energy and Services for the MEP discipline, as well as Dalkia, a famous EDF subsidiary.

For all Paris game buildings, there are two important phases, the games one as well as the heritage one, meaning that the buildings will be slightly reorganized before being handed over to the city of Paris in order to fit local needs. The specificity of this project is that it has also allowed the participation of local people in its construction in order to ensure a social impact for population, generating more than 110,000 working hours.

As you can see, badminton, rhythmic gymnastic, para badminton, and para weightlifting have taken place there during the games. On these two nice pictures, you can see the two main configurations of the main theaters, sport configuration mainly with basketball and concert configuration, offering a capacity ranging from 8,000 up to 9,000 seats.

Interestingly, on the left part, you can see this interesting interior view of the gymnasium with the half moon typical opening, and on the right side, the original and emblematic VIP space, including a panoramic terrace covered by this very human and original wooden tepee. Here, you can see a recent photo of a basketball game during the opening night once the building was achieved.

The Adidas Arena is located at the center of a rapidly evolving and very urban area which was not really well defined and which is surrounded by the Paris Ring Road, the huge Gare du Nord Station Railway offices, and many old dwellings. It's currently being completely renovated. And new constructions like the Adidas Arena will play an important and central role in this urban redevelopment.

Here is a more precise view of the project area called ZAC Mines Fillettes. The soccer field's boundaries on the right give you an idea of this urban district size. Let's have a look at some amazing numbers with, for instance, a 136 million euro global performance markets. 400 employees were involved. 43 months is construction duration for this design and build operation, a handover which happened at the end of January 2024, and the huge 10-years operation and maintenance contract for Bouygues.

In terms of materials, this is also stunning with 29,400 cubic meters of concrete, 1,500 tons of steel structure, 350,000 hours of work for structural discipline, as well as more than 6 million plastic bottle caps reused to create the seats. The structural work represents the real challenge with more than 18,700 square meters, more than 200,000 square feet of exposed concrete, and more than 4.3 kilometers of bleachers.

A quick presentation of the two architectural practices which collaborated on the design of these amazing buildings with first Scau, a famous architectural practice founded in the '70s and located in Paris with nearly 70 employees. They are famous for having designed the famous Stade de France or the Olympic Stadium, Ataturk in Turkey, as well as handling the Louver Museum renovation.

NP2F is a recent practice created in 2009 with 20 employees spread between Nice and Paris and working in various cities in France and abroad. They work on both architectural and [INAUDIBLE] projects of various typologies. Needless to say that these two practices are standardized on Revit and Autodesk solutions, like Autodesk Construction Cloud, Autodesk Docs, as well as BIM Collaborate Pro.

On this interesting view, you can see how this sparkling building is embedded between all these very industrial environments like the Paris Ring Road, the Northing Paris Railway lines. And this very dystopic landscape is both frightening and amazing at the same time with this nice pearl at the center.

Let's have a look at the mass plane in its initial state. Two soccer fields were destroyed, which gives you an idea of the size of the construction. At the bottom, Paris City at the center of the Ring Road, and at the top of this view, the suburbs of Paris. It's important to say as well that this is the only new construction that was created inside Paris for the purpose of the Games 2024.

This red rectangular shape at the center shows you the size of the space that was necessary for the creation of the Adidas Arena. It has a clear pivot and connecting row between Paris City and the surrounding areas, like the suburbs. Here is, again, the site mass but at a bigger scale. This is the second largest vegetal rooftop in the grand Paris with more than 6,900 square meter area. And 80% of the building surfaces are vegetated as well for air purification and thermal regulation purposes as well as allowing to avoid heat islands.

In terms of organization, we can definitely see that this building is articulated around three big spaces, including the main theater, a 700-seat gymnasium, as well as a multi-purpose one. This building will serve both for shows, sports events, training, Paris Basket headquarters, as well as local children and population usage.

Paris has always had this tradition to keep some of the most amazing buildings that were created for specific events like universal or international exhibitions or important entertainment constructions like the opera theaters. This will be an additional iconic building in the prestigious Paris heritage and skyline.

Here, you can clearly see the three horizontal layers of the Adidas Arena box, the ground floor serving as a main entry for spectators as well as athletes and artists. The first floor will allow spectators to walk around the central main theater and admire the exterior views of Paris during intermissions and breaks. And the third one hosts a VIP space as well as a gymnasium.

Here, on this section and elevation, you can understand the size of the central main theater with its almost triple eighths on the right side. The results, although minimalist and simple, is just amazing with this sparkling and reflecting box with an assembly of simple but very elegant volumes. The sparkling box fades away in the sky and sparkles when the sun is shining.

The architects have tried as much as possible to stay in a very pure treatment of interior spaces, reflecting the simplicity of the external shapes as well, with basic but pure and noble materials like timber, concrete, and steel all sustainable and partially recycled, like the bricks, for example, coming from the Grand Paris Hearst Diving, for instance, or the bottle caps to create the 8,000 seats.

All the HVAC systems and ducts also play an important role in the sonography of spaces like in some famous buildings as the Pompidou Center. As you can imagine, the drawings and layout work from the architects have been very important to obtain these pure results in order to get the final right look and feel in reality. This was made possible thanks to BIM and solutions like Revit.

The first layer of the Adidas Arena is an invitation to walk around the building and discover the amazing and brutal urban exterior landscape with the Future Express Train Line on its black bridge leading to the Charles de Gaulle Airport in the future. Everything has been thought, designed, and integrated, like all the technical systems and the ducts, a clear and strong architectural decision from the architects.

No space has been lost and no coincidence left. Here is another interesting perspective close to the main entrance at the ground floor. Here, again, you can see the clear and pure organization of the HVAC systems and lighting fixtures underneath the theater bleachers.

We've seen some planes and sections of the building in order to better understand it. Nevertheless, whether schematic or figurative, images offer a visual perception of the project, its shapes, or the architectural intentions. For the design of the Adidas Arena, the architect relied on three types of support, including end drawings, sketches, and Revit.

Finally, here is the so-called architectural BIM model. For architects, BIM is very important to plan, develop, and anticipate the real aspects and functions of the spaces as well as any other key information or media and data, like schedules, 3D views, 4D, 5D, 6D, 7D, VR, et cetera. It also allowed them to create any kind of simulation, like thermal simulation, solar radiation, cost estimation, logistics estimation, et cetera.

Revit definitely proved to be a central and very useful tool. It allowed them to produce and consult project elements simultaneously within a single digital environment between them and share it with the construction and engineering companies. A single environment is a precious source of work data facilitated by the powerful and unique software collaboration systems like the work sets and solutions like BIM Collaborate Pro and Autodesk Docs.

It was possible to manage the work of the two architectural practices located in two different geographical points of Paris through a single model with the powerful and flexible Autodesk Collaboration Cloud as well as BIM Collaborate Pro. On these pictures, you can clearly see how the model was divided between the two companies with the red and the blue boundaries.

This building, although simple externally, is extremely complex structurally speaking. It is important to understand here that moving from one configuration of seats to another generates a spatial change in the volume. To be able to represent this variation and make a decision, the architects organized the model with the help of different sophisticated filters and parameters in order to obtain 27 configurations of which we see a dynamic overview here.

From this model, it has become very easy to extract data like volumes, construction details, workforce calculation, or visual coefficient diagrams, et cetera. The modularity of the model made possible thanks to Revit was key to achieve these objectives. Due to the complexity of the project, architects had to optimize and systematize the construction principle.

It was, therefore, very important to have a close collaboration with the multidisciplinary design offices throughout the development of the project. The integration of technical disciplines models from the various stakeholders made it possible to validate the various architectural options in a fast and easy way, which is essential during the coordination phases.

The architects were also able to take advantage of the BIM model, in particular to create some stunning 3D renderings. The image at the top is a photo of the finalized building very close to the 3D rendering below, as you can see it. Here is another example of a 3D rendering created with Twinmotion and Revit. It brings great flexibility in terms of project visualization and control of the architectural objectives.

These images clearly show how easy it is to represent the architectural concept with the help of BIM and tool solutions like Revit. The image below helped to control, for instance, the lighting quality of a space, its organization, and structuring. And you can definitely see that we are very close to reality shown at the top again. We can see from these comparisons between photos and 3D renderings of the locker rooms that architects have been able to achieve their objectives.

To summarize, BIM and specifically Revit allowed the architects to produce a model that takes into account the programmatic complexity, the technical constraint, and the architectural challenges to guarantee a building that meets the architects' and owners' outcomes and expectations in the context of the Games 2024. After the architectural consideration, let's now have a deeper look at how the extremely talented teams from Bouygues Bátiment De France achieved this masterpiece. Gilles, the floor is yours.

GILLES VERSCHAE: Thanks, Emmanuel, for sharing the beautiful story and genesis of this impressive building. After seeing these beautiful images, let's dive into the project design and construction history. Please enjoy this short video to give you a taste of what we will discover now.

[END PLAYBACK]

As you may have guessed from this video, this has been a challenging project to design and deliver. First of all, it is a very dense building, hosting three major utilities and all the connected dependencies and technical rooms, the main theater with 8,000 seats and 2 gymnasiums. Of course, it means an intricate MEP design. And as you've seen previously, every duct is showing, no room for error.

To build this project, not only we had to work on an extremely dense construction site, forcing us to manage overlapping tasks and deferring some. But it was also on an immovable timeline. The arena had to be ready for Summer 2024. So to BIM or not to BIM was not an option.

As this installation sign plan demonstrates, we virtually built beneath our feet. We only had the blue areas available for storing purposes. The Revit construction site model was really helpful for managing logistics as well as helping workers to get oriented. Here, the view of these tents and factory-like setup of the construction site helping you understand the organizational complexity.

I mentioned some significant deferred tasks. As you will see later with Estelle, a large proportion of the main hull stands were delayed to make sure we could meet the deadline. MEP works on the so-called grill and the vegetated roof were both crucial and needed to happen simultaneously. Consequently, the lowest stance was built from the inside. Some head scratching meetings were needed to make sure everything went smoothly.

As a way to manage this, the BIM team put in place a tool allowing data visualization to help understand overlapping tasks, and more generally, to help visualize and contextualize different data in 3D. This exploded 3D model of the rooms is connected to various data sets through the famous BIM Link Plugin. And it allowed for quick analysis of this complex situation. Until now, not much of a consistent BIM model. Well, here it comes.

Let's now give another view of the different software we used. We had one important prerequisite being openBIM. Of course, there were many more software used than I will show now, but these were the most important ones. First and most important part is the 3D modeling, of course, with a great and efficient use of Revit along with specialized softwares like Bocad, Cadwork, and Tekla Structure for wood and steel framings.

For collaboration, we set up the Autodesk BIM 360 platform as previously explained. It was a great help for design documentation. And it allowed the two architectural practices to collaborate together. For construction documentation, we used a French government collaboration platform called Kroqi and BIM Track to manage BCF files.

Then, there is the classic data exchange add-ins. We also used Enscape, Twinmotion, and Solibri and Deluxe for different levels of visualization. BIM checking was done via Solibri and an internal tool based on Power Query. But I'll come back to this later on.

Here is a quick view of the various disciplines and BIM models aggregating into the big project BIM model. We have not been able to put every BIM model on this slide since more than 40 were created and used. We received mid-September the approval for nine gigabyte as-built model containing more than 40 BIM models through 20 disciplines, a great milestone we were proud and relieved to pass.

I mentioned a complex MEP model. Here, you can have a glimpse of its complexity. Keep in mind, it is informed for facility management purposes. So information's in every object.

This project had precise BIM expectations from our client monitored by the project management consultant. To meet these expectations, we established a strong BIM checking process. The task was substantial. We had 14 specific checks to run and needed to ensure that around 200 parameters were diligently filled for over 200,000 objects. Do the math. It's about 40 million values to check at each round.

Considering this, we performed approximately 275 individual checks during the as-built preparation with 3 to 15 rounds per BIM model, depending on the issues and the skills of the stakeholders. This generated around 300 work hours, including checks and follow-up meetings. It was a massive effort, but it could have been much more. Fortunately, we developed a dedicated tool that significantly sped up the BIM checks throughout the project.

So let's talk about this BIM checking process. Here is how we used to do it, mostly human based with minimal computer aid. Back in 2019, we needed about one hour to check a model. These models were less informed and complicated, but because it took so much time and effort, we mostly performed spot checks.

Today, things look different in many ways. Firsthand, openBIM gained a lot of traction as more stakeholders got involved. Managing IFC has become crucial. Secondhand, we observed an increase in BIM expectations, meaning significantly more parameters to handle. For a similar project, it means about 20 times more information to check.

That's why we computerized and automated our checking process. We currently need less than an hour to check more than 60 BIM models, providing us with a detailed view of our specific checks, but also, a comprehensive report on parameters fulfillment. Minimal human time is now needed, which allows us to focus on stakeholders management.

To dive in further down, we break down our process. First, the main principles that guided our work-- we rented off-the-shelf softwares and plugins. We tried to use little and simple programming to ensure easy upgrade and maintenance. And for our efficiency, we focused on computer time work rather than human.

As I previously stated, openBIM is at the core of our strategy. That's why the bulk of our data is extracted from the Solibri federated model. For models in Revit, we set up a Revit model checker analysis and used the HTML report. Then, we used Power Query to analyze the file server or drive. For our latest projects going on now, we are working on direct API connections.

Lastly, we still input some manual data from designated spot checks but only use these during thorough checks. And we are working on computerizing these as much as possible. Even though there is no big breakthrough, I will not disclose any trade secrets about this tool.

I will only tell you that our check-in tool is rather like Microsoft Excel file with Power Query specific data breakdowns and several macros. This allows us to digest all these data and compare it to the project requirements. We then produce a dashboard of overall and model-by-model quality checks and automatically produce individuals report.

OK, that's enough headache for now. I will give you a quick round around the different use cases we implemented before moving on to Estelle, who has a lot more to tell you with the art of pre-construction. As I mentioned at the beginning of the presentation, the arena now has the biggest vegetated roof of Paris, and the models were used for 3D coordination, making sure that the shape was perfectly integrated with the roof framing and energy.

We have a strong commitment towards carbon neutrality, down 30% by 2030 and net zero in 2050. This project contributed by using more than 400 tons of European low carbon impact wood, mainly for roof framings and the stands. We also used special raw earth bricks made from the rubble of the Grand Paris Express, a huge subway project all around Paris.

As a way to closely manage concrete formulas, we established a dedicated on-site concrete mixer plant. This facility produced low-carbon concrete, which we used extensively. The structural BIM model was used specifically to analyze and optimize the use of this delicate low-carbon concrete as well as precast concrete parts. The last technical use case, I wanted to show you is the solar and shade analysis. It aimed to ensure all-year comfort with minimal energy needs and allowed for the energy system's optimization.

Lastly, I wanted to share a simple but efficient use case for Project Communication. During the groundbreaking ceremony, we displayed posters for visitors to check and flash. We created a few viewpoints using Enscape. You can try two of them. First one is the main theater, and the second one is the famous half-moon gymnasium. Now, I will leave it to Estelle to share even more technical content.

ESTELLE JOULIE: Thanks Gilles, for sharing with us BIM model organization and use case. We will not talk about methods. First, what is methods? Methods consists of defining the organization that allows a project to be carried out within the client's deadline and budget. We must, therefore, define the human equipment and organizational resources of the project.

When carrying out our mission, we collaborated with a vast majority of the project stakeholders, the architects, the structural design office, the construction site teams, the site workers, the logistics, the planners, the equipment manufacturers, and the client. To carry out our [INAUDIBLE] methods, we were a team of up to six engineers during the rush period. We worked for three years on the methodologies, first on the design phases and then on the construction phase.

Given the complexity of the structure, it was necessary to work with 3D and BIM process, and therefore, with Revit. This team of six methods engineers worked in the single methods model. This was possible thanks to the Autodesk BIM Collaborate Pro platform. We produced over 600 methods documents.

For the method of the [INAUDIBLE] project, we used tools developed by Bouygues Construction. These tools are called micromethods. They are available in several subcategories of tools to design the site installations, construction methods, construction steps, security, shoring, construction equipment order.

There is a total of 35 tools. They allow us to be more efficient, more reliable, more optimized than classical methods tools. This tool helps calculation, managing settings, integration of internal rules and materials. We are then as close as possible to the reality of the construction work.

The first tool is microcycle, which allows us to define the construction method of the structure. At the arena, we added a complex interface, structural notes, concrete, 29,400 cubic meters of concrete, exposed concrete 18,700 square meters, straight and curved wall, steel floor and steel structure with beam of 90-meter span, wood floor and wood structure, half moon of 19 meters diameter to be made at a height of 20 meters, very high walls-- 20 meters for gymnasiums and 17 meters for main theaters-- 100 racks beams, including 83 prefabricated beams with some of them weighing up to 12 tons, 500 of rack cells from 3.6 meters high to 6.5 high.

These tools allow us to discuss with the architects and structural engineers how we are going to build the concrete structure Thanks to the specific template integrated into these tools, we can quickly define and update the construction method of each structural element.

The second tool is microcrane and microlift. These are tools to help us to realize the site installations. These tools allow us to configure the crane of the project. We can automatically dimension the right crane model. The tool allows us to quickly set the 15 parameters of each crane. It is connected to our crane catalog. We can order cranes for the construction site directly from this tool. We have the same tool for the site lift.

For the arena project in the heart of the North of Paris, we have a complex site installation constraint between the Paris Ring Road, the Northing Paris Railway Lines, the Highway Line linking Paris to the North of France, the Internal Boulevard. To carry out the project, we installed six cranes, one central concrete pouring mast, one on-site concrete plant, one lift, [INAUDIBLE] size for 400 [INAUDIBLE].

To facilitate access to the site and to each workstation, we generated a welcome video for worker and visitor with the Enscape software. We also used Enscape to create immersion QR codes. This dedicated point of view allowed us to exchange with the customers, the security service, and the neighborhood residents on our future site installation. You can try it with the view from the cab of our number four crane.

We have another tool called microarchi. This plugin allows us to present detailed drawings to the architects and have our construction steps validated so that it confirms their wish. The microarchi plugin allows us to generate the impact of the concrete of all our formwork tools on the 3GP model. Then, that means that each and all of and each joint of formwork had to be planned and validated. You can see on the left photo of the work carried out to the right extraction of our model methods.

On the [INAUDIBLE] project, we had the challenge of creating 18,700 square meters of exposed concrete. For each square meter of concrete to build, we used microarchi to generate all the impact on the concrete of our formwork. You can see the measurement for each [INAUDIBLE] and curving and formwork drawings. Here is a formwork for the half-moon. Each panel has been precisely positioned in Revit. With our study presented to the architects and update 1.5 kilometers of layout plans.

Now, I am going to talk to you about microshoring. So this plugin allow us to automatically generate shoring, including shoring towers. It's automatically positioned and adjust the tower height and various parameters and configurations. We can then extract the [INAUDIBLE] schedules ready to order.

To accommodate the 18,000 seats of the project, we installed 450 prefabricated bleachers with six different type and 4.3 kilometers of bleachers. These bleachers were then set in place on 100 racks and pinion beams. To be able to install these racks and pinion beams, we used micro sharing and microcycle to precisely organize the steps of installation of the prefabricated elements.

We are strongly committed to security. That is why we have another tool called microsecurity. This tool automatically generates safety walkways to ensure the safety of our workers. To build the project, we had to use 150 safety walkways on the main theater and 30 safety walkways for the gymnasium. These 180 safety walkways were all different. Each safety walkway has 20 settings.

Microsecurity allowed us to quickly adjust these 20 parameters per walkway. After configuring the walkways, microsecurity automatically generates the purchase order for each one. The main theater consists of a 10-meters-high base. On this base, a wall of 17 meters height is placed.

This concrete structure has been dimensioned with finite element models. This wall of the main theater contributed to the overall stability of the arena along with the steel framework. To carry out this work, we set up a double safety suspended walkways. There was a total of 150 walkways to lift and raise for each level. These walkways have been modeled with our microsecurity tool.

So at Bouygues, we created operating mode for each task that a worker realized. We made sure that every person who starts working with us is trained in the task they realize. These operating modes are designed by the method department. We have a full library of standard operating modes containing more than 150 3D documents. They were designed over 10 years by a team of method and construction site experts.

On the arena, we added several complex structures that did not exist in our standards-- 17-meters-high main theater wall in four steps with specific geometries, 12-meter-high gymnasium wall to pour in a single step, which is very delicate, a huge half-moon to recreate a spatial formwork, the bleachers, the racks.

We studied and designed several specific operating modes. We decide to carry out all specific operating modes in 3D microcycle tools for organize the steps. We have also converted some operating mode to 4D for better visualization by the workers. These operating modes were for presentation directly in the model for site workers, project owners, safety, labor inspection. Here, you can visualize the operating mode of the half-moon. Take a moment to flash the QR code.

To ensure the timely and safe completion of the main theater, we set up a coordination support between the different companies working in this area. This coordination document was created with the Twinmotion software. This tool was used during the construction of the steel framework of the main theater. It allowed us to coordination the different simultaneous jobs in the main theater between the different disciplines, including the structural work carried out under the steel formwork.

We used Twinmotion as 3D viewer in the drawing phase as well as in presentation to anticipate logistics and connectivity issues, to work safely, create interactive documents to lead our coordination meetings.

GILLES VERSCHAE: Thank you, Estelle, super interesting technical work. I used to work in the methods department. And sometimes, I feel like if Excel and [INAUDIBLE] ties me out, I could go back there. So interesting. Now, last but not least use case, the project team tried an innovative way to collaborate between methods team and construction team in BIM level 3. Yes, I said it, BIM level 3 localized, compartmented, and manageable.

Thanks to ACC, the methods BIM model was shared and made accessible to the construction team. Special views and sheets were made on purpose for them. They populated it and used it for monthly, for weekly, and for day-by-day planification. It was a real organization tool, and it greatly helped the acceleration plan that was put in place to meet planning expectations.

These views and sheets were used during meetings and in the day-to-day life of the construction site. Given the high complexity of concrete work you witnessed earlier, the great architectural expectations for concrete wall layout plans, it has been a key tool for achieving success and meeting the 2024 Games' tight deadline.

Well, that's it for this tense presentation. We thank you so much for your participation, and we all hope that you enjoyed this session. We sincerely wish it motivates you to either start or continue your investment in BIM and maybe accelerate even more your BIM journey, maybe with AI as well. Thank you.
