说明

How do structural engineering firms use building information modeling (BIM) as a comprehensive tool to provide different stages of drawings submission through BIM? Through the expertise of the BIM team and the Pinnacle in-house add-in, the structure engineering team has achieved 90% efficiency in the design project handover, with 50% time savings on design, coordination, and drafting work. Come to see how this 1) helps the architecture, engineering, and construction (AEC) industry optimize resources, cost, and quality through the innovative use of technology for the entire project lifecycle and 2) enables accurate and automated manufacturing of structural connecting parts (connecting plates, bolts, and so on). Also, see how bar bending schedules and automated rebar cutting and bending help reduce wastage and increase efficiency on site.

      CHANDAN SUTRADHAR: Today's topic is BIM Based Structure Engineering: Seamless Workflow-Design to Construction. We'll talk about today, these are the learning points-- seamless transition from 2D to 3D, engineers and architects work on a single platform, faster and efficient design with automated iterations, quick implementation of multiple design changes, simultaneous access to the cloud server, and connect design to construction drawings.

      Who am I? I'm assistant general manager at Pinnacle Infotech Solution, 17 years experience with leading more than 550 projects, providing the innovative BIM technology for the AEC industry, providing end-to-end solution for the design preconstruction and construction management. And I've been working and familiar with the facilities management workflow.

      Let me introduce my co-speaker. He's the name that you can imagine, it's begin the origin of BIM, Bimal Patwari, BIM itself, inherent in this name. So he's the founder and the president of Pinnacle Infotech Solutions. And his passion is stretch the technology to provide innovative solution to the AEC. He's a regular speaker at major conference and global events. And more than 7,500 projects and BIM implementation being done in 41 countries. He has received many awards and recognition worldwide.

      BIMAL PATWARI: Thank you, Chandan, for the nice introduction. Friends, Pinnacle is the global leader in the AEC industry. We have been in business for more than 30 years with 1,100 satisfied clients all over the world. We have done more than 7,500 projects across 40 countries.

      The most important thing about us is that we bring all the trades under one roof. The projects today are very complex. They require fast execution, a lot of coordination between so many trades. So what we have done is brought we have brought all the trades under one roof. So we are a team of 2,300 architects, civil engineers, mechanical and electrical engineers from all the trades, so that we can give a combined cohesive turnkey solution. Next.

      Friends, let's discuss about our traditional way the AEC industry has functioned. We all know that the productivity gains in our industry has been minimal in the last 100 years. Still, we have the different stakeholders working in their own silos and a very sequential workflow. So the owners give the requirements for the architect, architect does the basic concept design, which is then taken up by the structural engineers, which is subsequently worked upon by the MEP engineers and the different consultants on any project.

      As we all know, the communication between all the stakeholders has been very zig-zag. We know that during the design process, there are so many changes that takes place. Because each of the consultants, they want to meet the requirements of the owner. They have to go through the courts. They want to optimize the design. They look at various options.

      So the design changes are unavoidable. And there is no way to keep those design changes, especially in very large complex projects, where there are so many trades involved. And we know how the communication takes place.

      And nobody is aware of, which is the latest find. Sometimes the structural engineering is working on a file, which has already been updated by the architects and which is true with all the stakeholders in the work room. Next.

      So as a result, what we see the traditional workflow that we have has a lot of problems. It is highly inefficient. It is error-prone. And it takes a lot of delays, because if everybody is waiting for the structural engineer to make the structural changes before the MEP consultants or other consultants can work on it.

      So this process is full of delays, full of inefficiencies. And it leads to much higher design cost and design time. And the worst thing is that we end up with suboptimal design due to this workflow. Next.

      So the benefits of the BIM integrated workflow-- so BIM has brought a paradigm shift in the industry. I think it is time that our industry adopts this new workflow. I know there are pockets of excellence around the world where people have adopted it. But then there are a lot of places it is still to be adopted.

      And I hope today's presentation will motivate those people or tell them the ease of implementation, the benefits, and the challenges of the BIM integrated workflow. The biggest advantage of the BIM integrated workflow is that there is one single model, which is accessible online to all the stakeholders. So there is one single source of truth. There is one single model, there is one single cake on which all of us are working together.

      So that any change is made by the architect, if the change is ship the walls or the ship the doors or windows, or they do anything, immediately, that change is reflected in the central model. And it is available to all the engineers and consultants. And those implications of design changes are known to everyone.

      So immediately, all the other stakeholders can work on it. So the structural engineers then, can accordingly work on the structural design. That MEP engineers, they want certain sleeves. They want certain ceiling space.

      So all these things now, are updated by the respective stakeholders. But there is one online model there is one single source of truth. As a result, we see there is a lot of time that is saved. There is no more to and fro exchange of files between different collaborators.

      Naturally, the design time reduces, the effort reduces, the cost of design also reduces. Now the designs are much more optimized. When Chandan will discuss subsequently the workflow, you will see how this collaboration can reduce our design cost, can reduce our project cost, and bring more certainty to the project, most important that we have to ensure that whatever drawings, whatever model that we finally give it to the construction team, it is constructive, it is the most optimal design, and how this error-free iteration can take place. Next.

      In face, this is what we have because at Pinnacle, we work on both sides of the table. We work with architects, we work with the structural engineers and MEP engineers. And we also work with the contractors.

      So when we work with the architects and engineers, we have easily seen that there has been almost 40% reduction in design time across several thousand projects that we've already done. And that's a 12% reduction in the project cost. And we'll come to that, how this change in the workflow is actually bringing value engineering and is able to reduce our project cost. And these are our figures that we have verified with all our clients. And it would be our pleasure to present before you, how do we achieve these numbers, how can we improve further on these numbers.

      CHANDAN SUTRADHAR: Thank you, Bimal. Like what you have said, excellent. You have given a brief idea of what we are talking about and the basic difference between the traditional process and the structure the BIM integrated workflow. So I'll go through, one by one, the benefits. And then we'll talk about the workflow.

      First, is the improved collaboration. As Bimal said, Autodesk has created Autodesk Construction Cloud. And it's a centralized documentation process, where all the people can work together in a single model.

      It provides you a single source of truth. And while people for architect, MEP engineers, they can work in a single model with their team members. And they reduce a lot of disconnectivity between the stakeholders. And it creates a better workflow between team and data, every stage of construction, reduce the risks, maximize the efficiency, and increase the profits.

      So we will talk about Autodesk Construction Cloud. Many of you have been used BIM 360 earlier. And you know from February 9, 2021, Autodesk's BIM 360 rebranded with Autodesk Construction Cloud. Earlier, Autodesk BIM 360 Docs, now it is Autodesk Docs, BIM 360 Coordinate, it's now BIM 360 Collaborate.

      Now earlier, the BIM 360 Designs, now it's Autodesk's BIM Collaborative Pro. And earlier, Autodesk. the Takeoff was not been there, now being introduced. So Autodesk Docs is for the more focused on the document management. BIM Collaborate is for the design collaborations, single class coordination, easy management. And the Autodesk Build is providing completely document management.

      And Takeoff is like you can have an opportunity in Autodesk Takeoff, do the 2D takeoff, as well as the 3D takeoff. Apart from this product of Autodesk Construction Cloud, we have an option, Autodesk Ops, in where we can do the handover and facilities management activities, the asset management activities.

      Like architect is crazy like for the changes based on the requirement, so anytime, they made a change if you want to make the control. So Autodesk's Construction Cloud provides you complete control of each individual model status. From this legend, we can understand which model being published and consume. The color codes has defined. Green mechanical file-- publish and consume, structure file-- publish and consume, the field things are being published.

      So if you want to verify which model is updated, we can click and consume. That would be overloaded your link files. And you can also verify and compare the two versions of model architects that has been changed. So it's giving a complete dashboard for overall model control whatever. What were happening or whatever things are going over here, we can see each individual situation.

      Now we talk about the real-time coordination. While we are uploading or seeing the individual data model, Autodesk Construction Cloud provide you automatic detected classes. And it's like filter. You do not need to review each individual. It's customized.

      And those classes, the numbers you can see here, these are the rvt file, left-hand side. And these are the numbers of conflicts or classes between each trade. And those trades, we can assign a particular person to take a look why and what the classes between them. And those class can be rectified by the individual concerned people.

      So here you can see, the concrete beam conflict with steel structure to steel structure beam. And we can create those quickly. And those issues can be addressed to the concerned person for the proposed solutions. So click, and then these are the issues BIM gave automatically. And we can assign to particular people.

      Easy design changes-- this is happening. Industry says that based on the requirement of the architect and the owners, the design change can be happeninh many times. And those changes then has an opportunity to provide a very quick and easiest way to solve those changes with the software applications. So we would like to serve with a video file, which explain you what the changes, how many changes.

      Like there are 200 beams that need to be changed by the specification, like W 12 into 200 need to change with W-14 to 400. So that has been changed very quickly. And how it is happening, let me show you quickly on this video.

      [VIDEO PLAYBACK]

      - Easy design changes. Condition-- when there are multiple design changes happen in a project as per requirement. 1-- select BIM type from plan. 2-- change the BIM type from properties. 3-- changes will reflect automatically in plan, schedule, and section views. 4-- similarly, any changes to the schedule will be reflected in the plan, section, and 3D view. Benefit-- it saves a lot of manual time and effort.

      [END PLAYBACK]

      CHANDAN SUTRADHAR: So you can see this model, a very fast way we can change the many numbers of specification for the structural members. Similarly for the concrete or the architectural, whatever the elements you want to change, that could be done very quickly.

      Now another review, help that BIM is providing during design phases, constructability review and the value engineering. So there are a lot of mismatches in between two documents. And certain things, we can identify based on the drawings review, based on the 3D model compared with the drawings.

      In this picture, you can see the slip location and the BIM are conflict, which are not possible to identify in the 2D platform. And also, many areas could be identified, like input inconsistency between two drawings, installation and code issues, the command and operation clearance, conflict between drawings and the specifications. So let me give you some more examples we would like to see in the 3D view.

      These are the constructability review. We can do earlier to the constructions between the drawings, when we're doing the models. So missing data, data conflicts, code issues, input inconsistencies, construction feasibility, operational issues. So let me go through quickly, one or two examples of this.

      [VIDEO PLAYBACK]

      - Missing data issue-- as per the structural and architectural input drawings, the staircase dimensions were missing. After a constructability review, we raised an RFI with the client and received a response with the dimensions. Here we have used the dimensions that have been used to model the staircase.

      Resolves operation issues-- as per the input, the space between the staircase and the elevator and the office building was getting overcrowded during rush hours. After constructability review, we oriented the elevators face towards the access door to free up space, prevent overcrowding, and facilitate easy access.

      [END PLAYBACK]

      CHANDAN SUTRADHAR: So this is only possible with help of BIM. One more beautiful examples we'd like to share with you guys, what we can do with BIM. We can identify a lot of value engineering part in the building site, during the building modeling, during the workflow for design coordination, class coordination. Here is an example.

      We have found Parapet wall height was given plan around 7 feet 10 inches and the section 3 fit. So what we are trying to say-- if the first set of drawings, like 7 feet goes to the construction site, the Parapet height would have been done in construction, resulting dismantling and the rework later. So we have calculated the rework like the volume of the concrete columns and the steel and the formwork, and in terms of other items and the finishings.

      So we just given here, a little bit example like the unit cost of individual concrete, and calculated around $15,327 cost saving through these activities. So it not only saved the material, it also saved the time. It also saved total cost of the construction.

      Visualization and simulation-- that's powerful thoughts I would like to share with you. It provides excellent project insight. The structural engineer can quickly separate the elements anytime from the combined models, filter any idea or spatial interest from the structural element that they want to see, enhancing its understanding and facilitating, solving problems. Any kind of conflict between the structural architecture element or visibility change the transparency in 3D views, that allows more transparent review of the items.

      Autodesk Construction Cloud not only provide the 3D view in a computer, there is no need to bring so many papers, so many papers and things into the site. We have an opportunity through mobile or tab. We can view files. We can access the markups individually which mostly using the Navisworks Manage. But we can review the classes and the viewpoints on the tab. So this is another benefits that the structuring integrating without swimming in the individual papers or do not need to carry about that at site.

      Now we will talk about how it is happening. We talked about a lot of benefits. These are the benefits what from the BIM Comeoffs. But we will discuss about, in detail, how BIM integrated workflow provide you more benefits out of that additional workflow.

      Firstly, we need to follow the families and the library. So being the BIM Revit software has a facilities where you have a lot of families over there. And these families and library you can utilize to prepare any kind of building structure.

      First you need to develop the 3D model, the physical model based on the design content. You have an opportunity, design options like in Revit workflow, where design option is the most popular thing, if any have been used that or if any of you have been familiar with the design option, that awesome. Otherwise, we'll talk about that.

      Design analysis and the optimization-- so it's a little how it is happening in the software and back and forth between Revit and Robot Structural analysis, that optimization shape and size and specification of the members. That, we'll talk about. Construction drawing from a single model-- from design stage to construction stage, single model with all of the updates and drafting views, everything. We'll talk about that.

      And the last one, the quantity Take-off-- it's a detail quantity take-off, which will enhance the procurement team, which will enhance the stocks engineering team at the beginning stage to get all the budget and the quantities. It helps a lot.

      Let's talk about Step 1. Before we go to the Step 1, I need to give a broad picture how a single model can help you and catered all the purposes in the industry. This single Revit file, you can bring into the Robot Structural analysis platform, where we can do analysis and where we can change the specification and bring back to the Revit file.

      So analysis part can be done from the single model. If you have a workflow where you need the 4D simulation, 5D simulation, and class coordination work, the single model we can bring into the Navisworks Manage platform, where we can perform this activity from this single model. Similarly, there are a lot of apps. Autodesk's app store providing you with repetitive tools, the free add-ins, where you can get a lot of typical activities, ideas you can download from their. Dynamo Studio and the others are there.

      The single model also, you can bring into the advanced tool, where you can do the fabrication work. And you can provide the fabrication for construction. The single model-- from there, you can bring into the Rebar, Autodesk's Rebar drawing, 2D drawing that you can do separately. So the single source providing from design, analysis, and fabrication.

      Firstly, parametric family and liability-- the Revit BIM software has a library of parametric components. It also allows for the storage of any new components and/or added to its existing components and its liability. All modeling BIM tools work with parametric objects. You may have option to download the Revit family in different sources.

      So like you can see, the concrete column B pile cap, structure wall, trusses, joist, bone beam, single section. All these families are in there. We need to change those if required based on the specification and the design criteria.

      So what we have to do there in the second step, we have to prepare the 3D BIM model using the different families, different components. And you have to complete the all connection. So it means the analytical model should be prepared perfectly. With the structural Revit platform, we have an option-- the analytical line, analytical model could be created. And this model would be utilized in the next steps.

      Let's give you a design option why and how it is helping in industry. For a single model, if you have a steel column and concrete column, both you want to see how the looks and how the load calculation everything, you want to see. So first picture, it will give you design option one and two, where the steel column and concrete column, same flat roof framing.

      Second, third, and fourth options is given-- rectangular footing and the pile cap, flat roof framing, where there are two options. The concrete columns are there. And the pile caps are there. So the two options can be sourced in a single file.

      Similarly, design option five and six, rectangular footing, pile cap with slope roof framing. So rectangular footing out there and the pile cap. So all this option, you can do it in a single model. If you want to see which is the better design, you can identify based on your requirement.

      So design option not only help you to identify the better design, to see the opportunity, how many options you can create in the design options. Earlier, if you remember, while we were working on the 2D platform, we need to create alternative layouts. And those alternative layouts will require more times. And also, there is a missing in the connectivity sometimes. So this design option give you a better opportunity to find out the different designs from a single model.

      Design analysis, the third stage-- in this stage there is an option from the Revit model that we have talked about, that analytical model and analytical lines should be present. So those analytical lines and analytical model, we can bring into the Robot Structural analysis software.

      And Robot Structural analysis software, where we can do the load analysis, testing, and also we can check the different wind load condition. Everything we can check what they are based on the design and load criteria, we can see whether the specification required to change or we need to replace with a different member setup. So we can change the specification inside the Robot Structural analysis and bring back into the Revit platform. So we do not need to change into the Revit again.

      So it's a smooth and single direction, bi-directional operation, where your model not only prepare the physical model. Also you can make the design analysis with this bi-directional process. We have a different source of software in the market. Those are common software people are using that, like remote RAM Structural analysis, SAP, Tekla structure, Strand.

      So those platforms are also having an opportunity from the Revit, we can export the IFC. We can export the bidirectional option we have there. And the people who are using, they can also continue with that options.

      Let's see one by one, how it is happening. So first we need to create geometrical models in Revit. And then Revit model goes to the analytical model for the analysis part, like the test, train, and load analysis in the Robot Structural analysis. While we can change the specification in the Robot Structural analysis and the final model goes to the Revit file automatically. So this bi-directional option give a smooth process to make the individual changes automatically.

      I have collected one video from Autodesk website. And each gives you a quick idea of how it is happening. Let's go through it.

      [VIDEO PLAYBACK]

      - Traditional structural engineering workflows could involve a variety of challenges. Structural engineers typically start the design process by getting familiar with the architect's design by interpreting architectural drawings or general 3D conceptions. Because the structural designer or engineer creates both the physical and the analytical model concurrently using Revit software, the data can be entered once and used for different purposes.

      In this example workflow, a structural designer creates the physical and analytical model and exchanges these designs with a structural engineer, who then, the extended team of structural engineers can easily review what has been done in Revit and the current state of the structural project. A structural engineer continues the design process by performing structural analysis and running code-checking optimization.

      The Revit analytical model can be sent to Robot Structural analysis professional with all the information needed for structural analysis, including boundary conditions and loads. In some cases, the engineer may also decide to make changes to the model prior to analysis, based on their experience or access to advanced simulation tools. For example, the wind load simulation feature lets users simulate wind flow around a structure and generates wind loads automatically.

      Once the analysis has been conducted. The engineer can easily explore the results and begin designing structural elements. Robot Structural Analysis Professional is a powerful tool not only for calculations, but also for visually exploring results. With multiple ways of presenting analytical results and the ability to easily access them, structural engineers can very quickly prepare the final structural documentation for review by project stakeholders.

      Next, the structural engineer can run co checking of the structure to verify and design steel members based on a wide variety of national and international codes. The first step in designing structural steel is to organize the bar elements-- beams, columns, braces, et cetera, into member groups. Each member in a group will be assigned the same section by the design process.

      The engineer can also select optimisation criteria. Once the design group is optimized, a simple Change All button allows all new sections to be applied to the model. Once the Revit model has been updated after the analysis and code-checking process, the structural engineer can upload a new version of the Revit project to BIM 360 Docs.

      This summary provides a quick overview of changes made by the structural engineer during the code-checking process. With BIM 360 Docs, structural teams can manage 2D plans, 3D BIM models, and any other project documents. This streamlines the connection between design and fabrication.

      [END PLAYBACK]

      CHANDAN SUTRADHAR: So you can see how it is helping from design to construction. And then analysis part can do very quickly. Let's talk about how from the single model, we can develop foundation plan, floor framing plan, and roof framing plan for the construction drawings. We can create the best families. You can create elevations. You can create typical details.

      We have an option like drafting and detailing section, where we have a detailed library of the components for each individual like the rebars and the start and the start rail. And the typical foundation details, we can create in the limited inside itself. So the complete construction drawings we can create from the single models. And we have an option-- the annotation part, the dimensioning part, those-- all the parametric families will help you to allow you to reduce the times, not only from the light model. Like if any change in the specification, it will change in all the drawings, all the plans, floor plans, the elevations. So it helps a lot to create a complete construction drawing from the single source of model.

      BIMAL PATWARI: Thanks, Chandan, for explaining in details the transition from the traditional workflow to the BIM integrated workflow. And as we have seen, that how, in the BIM integrated workflow, the entire process is so efficient, so transparent, it eliminates the source of error. There is one source of truth, which is online, available to all the stakeholders. And finally, once we are complete with the design, we are-- and we have done all the coordination, we have done all the constructability review, we have done all the value engineering, we are able to generate all the detailed shop drawings, very well-dimensioned, with all the details required for construction.

      Now there's another very important benefit of this whole process. That is quantity take-off. We want also to know, during the construction, that what is the total quantity of concrete. What is the total quantity of different material that is being used in the construction? We even want to know what are the different grades of concrete? How much concrete is required on a daily basis?

      We want to do the 4D analysis. We want to help the site in letting them know how much of concrete, or any other material, or structuring material, or whatever it is required on a daily basis. So let's see how we can do the quantity take-off. Next, please.

      So one of the advantages of the 3D model, the 3D workflow, is that we can indicate, as you can see in this model, all the columns and the column base. We are able to depict them in different colors to show the different level of elevations or different concrete strengths that we may be requiring. And we are able to estimate the quantity of each type of-- whether it's CMU wall, whether it's concrete wall, whether it's brickwork. Whatever type of material it may be, and whatever type of specification it may be, we can extract these quantities as we want.

      And the best part is that we can even check the change management support. If there is a change in the design, then what is the impact on the quantity? It can immediately tell us that. Because the model is updated as soon as support, or column size, or the footing is changing, we can immediately know what is the impact it has on all the material, or the labor component, or the machinery, and the schedule. It is very easy to determine that. Next.

      We'll show you a small video to explain how the quantities can start-- can come out, and how smartly, with the design changes, this happens.

      [VIDEO PLAYBACK]

      - Smart schedule integration in Revit.

      So as you can see in this video that has been demonstrated, that how, in the Revit model, we can quickly identify the material or our target-- the columns, or the footings, or whatever it is-- and then what are the changes that have come, and what is the change in the quantity or the schedule that is reflected here? And all of them we can get it by the click of the button. So this is the beauty of the whole process.

      CHANDAN SUTRADHAR: Yes, sir. It's true.

      [END PLAYBACK]

      BIMAL PATWARI: Another big advantage that comes on the table, and as we have seen in the beginning, that we strongly believe that we need to bring technology. We need to be on the edges of technology. There is so much of potential to use the technology available to improve our efficiencies, to reduce our error, to meet our unrealistic schedules. It has become very important that we bring a lot of automation. And we do specialize in creating different automation tools, different productivity tools. And we would like to show a couple of examples here to demonstrate how, by automation, we can really reduce our time. And we can also reduce the error, improve the quality of our design.

      For example, here, now the individual column placement-- now if the doors have different door heights in a particular project, now obviously the column placements will be different for different door heights. And we very often make mistakes, because the door heights are different, and we miss that. But when we write a program, a simple Dynamo script, the user can place the accurate structural columns beside the door openings by single click. And this ensures not only fast execution, but also eliminates the chances of manual error. Next.

      Similarly, this is another good example of that sometimes the view placements are changed in a drawing. And immediately, we want them-- the sequence needs to be updated. So again, these are some of the fallacies of the 2D traditional workflow that we have seen. But once we are into this 3D workflow, then we are able to write simple Dynamo Scripts, which can, again, renumber and rearrange all the sequences of the drawings, of the elevations sections in the drawing, which of very help. It

      Eliminates-- and especially if a project consists of hundreds of such sheets-- in the design process, we often see that the designs are changing. And manually keep updating each and every sheet and each and every sequence is a nightmare. So here, again, with a click of a button, we write some great Scripts which can renumber and rearrange everywhere in the sheet, and saves us time, and eliminates error. This is a simple Dynamo Script. We are just showing you a workflow which we can do that. Next.

      This is another of our very favorite examples that I've seen across the 7,500 projects that we do. In every project, there's so many systems that penetrates the walls, the structural walls, the CMU walls, and every type of wall. And it is very, very important that we cut those sleeves. And not only just the pipe, but we need to have the right sleeves which is positioned so that the pipe can go through those sleeves. We have to be very careful.

      And we have written various programs where the pipe sizes and the sleeves are mapped. And you know that if it's a 3-inch pipe then what will be the size of the sleeve, and like that. So the system picks up the various sleeves for each type of pipes, or ducts, or cable trays. And then it cuts automatically into these walls these sleeves, which saves amazing amount of work, and of course all the errors. So that when we create the builder's work drawings, when we create the elevations of these walls, all the sleeves are accurately placed and shown in the elevation drawings.

      We would like to show you a quick video here.

      [VIDEO PLAYBACK]

      - The tools used to automate the beam alignment with slope floor by Dynamo Script.

      Condition when there are multiple beams are drawn straight and the floor changes the slope as per requirement.

      BIMAL PATWARI: So here, in this video, we are trying to align the beams according to the changes in the floor slope. And it can be very easily done. And it can be automated now. So whenever we change any of the slope conditions or any of the conditions there, automatically the Dynamo Script changes the structural framing.

      So as you can see, the frames are being aligned.

      So as you can see, the conventional time, which is three to four hours for these adjustments, now we are able to do that in 15 to 20 minutes.

      Now this is another great example to automate reinforcement and PT-- reinforcement in any structural column, which all of our structural engineers, we struggle. Because after our slab design to place the rebar, there are various simulations based on which we can do almost 80% of the rebar. The first round of rebar placement, we can automate that. And we have very successfully done this. And a lot of structural engineering firms are using this package to reduce, very significantly, the time taken to place the rebars and the reinforcements.

      This has been-- but there are so many standard rules which we are using. And the system, we are trying to make it now intelligent using AI tools so that it learns. There is a very different type of, say, concrete structure if it's a semicircle, or round, or different kind of edges are there. So the system will be able to learn that, during this change in the boundary conditions, what is the impact on the rebar placements? And the idea is that if we can automate the first round of these rebar placements, it can save very significant amount of time.

      - --benefit. Therefore, the tool is very useful based on predefined design rules. All the functions will work based on provided values from the related UI. It's a time saves a lot of manual effort and times (80%).

      BIMAL PATWARI: So this is, again, a tool which has been developed by our company. We have the PT dead end clearance. We have to define certain design considerations, like the floor thickness and the distance of columns that we need to reconsider. And it is automatically able to place the reinforcement and the PT for most of the columns.

      - Automatically will be drawn the PT tendon & Draft at Level 2 Check other similar levels and we can apply it Left & Right, Top & Bottom.

      BIMAL PATWARI: Like left and right hand side and the both directions.

      CHANDAN SUTRADHAR: Exactly.

      BIMAL PATWARI: And the best part is that we are trying to bring AI into this so that whenever it encounters a new type of structure or a new type of situation, it can learn from that. And next time, it is able to update its database. So almost 80% of the manual effort and time can be saved by using this tool.

      So this is just an example, I mean just the tip of the iceberg.

      And today, we really need to take our industry and improve our productivity, improve our automation. We need to innovate. We need to bring-- disrupt our industry. Because all every other industry has tremendously gained over the last 20, 30 years. And we are really lagging behind.

      We hope that today's presentation will help you to understand this workflow. And this has been very successful. And please feel free to contact us. If you have any questions, we'll be very happy to respond to you. Thank you for attending this session. Wish you all the best.

      CHANDAN SUTRADHAR: Thank you, everyone. Thank you, Bimal, for explaining very well. And thank you Autodesk for providing this opportunity to explain and share our thoughts. And I hope this class will help to all the structural engineers to apply in the industry as soon as they can. And really, it will be beneficial. And it is a good time. As Bimal said, it's the time that we need to understand and to amplify this BIM integrated workflow in our industry. Thank you very much.

      BIMAL PATWARI: Thank you.
