Description

[0001] “SYSTEM FOR GENERATING WORK BREAKDOWN STRUCTURE

[0002] BASED ON BUILDING INFORMATION MODELING”

[0003] FIELD OF THE INVENTION:

[0004] The present invention relates to generation of work breakdown structures and more particularly relates to construction scheduling systems for rendering construction schedule planner based on work breakdown structure.

[0005] BACKGROUND OF THE INVENTION:

[0006] In construction project management, effective planning and execution require decomposing a complex project into smaller, manageable tasks. This structured decomposition ensures clarity of scope, improves accountability, and facilitates accurate cost and schedule tracking. A Work Breakdown Structure (WBS) is the fundamental tool employed for such fragmentation.

[0007] The WBS integrates scope, cost, and schedule baselines into a single framework, thereby ensuring that project objectives remain aligned throughout the lifecycle. Broadly, WBS models may be classified into two categories. A deliverable-based WBS establishes a direct relationship between project deliverables such as products, services, or results and the corresponding scope of work required. In contrast, a phase-based WBS organizes work according to project phases or levels, requiring activities associated with multiple elements to be divided into subsets unique to each defined level. Existing software solutions have attempted to provide partial support for construction planning workflows; however, such solutions do not adequately address automated generation of a Work Breakdown Structure (WBS). By way of example, Autodesk Assemble and Autodesk Takeoff are directed primarily to estimation workflows, enabling users to derive quantity predictions from Building Information Models (BIM). Although these systems permit definition of a WBS field at an individual model element level, they do not provide a structured or automated workflow for creating schedule-oriented WBS values. Consequently, generation of an appropriate WBS remains a largely manual task.

[0008] Further, Bentley Synchro 4D is a construction management platform oriented toward planning and operations, and provides a 4d planning workflow based on Building Information Models (BIM). The system operates using its own version of the BIM model and does not natively integrate with external document management platforms, such as Autodesk ACC.

[0009] In use, the generation of a Work Breakdown Structure (WBS) within Synchro 4D requires manual tagging of model elements, as the application does not support automated assignment or creation of WBS values. Accordingly, the system continues to rely on manual intervention for WBS generation, which increases the effort and possibility of human error.

[0010] European Patent Application EP 1643335 A2 to Graphisoft SE teaches a system and method for designing and scheduling building construction. The system includes a three-dimensional design module that generates design data using one or more elements arranged in a spatial tree structure. Recipes are associated with individual elements, each recipe comprising one or more method components, and each method component further comprising one or more resource components.

[0011] A cost estimation module generates cost data using the associated recipes, while a scheduling module generates schedule data based on the same. While this approach integrates design, cost, and schedule through recipe-based associations, it does not disclose an automated mechanism for generating a hierarchical WBS directly from BIM geometry and metadata.

[0012] Korean Patent Application KR 20200002472 A to Seo Jun-seok describes a building work classification system configured to classify building work by combining multiple classification dimensions. The system employs a vertical classification (e.g., floor or height), a horizontal classification (e.g., facility type), and a designated classification (e.g., specific work or area).

[0013] These classifications are represented as three-dimensional data, wherein the designated classification may be multilayered, and building work is determined based on one or more of the vertical, horizontal, or designated classifications depending on the work type. Although this system provides a structured classification framework, it does not disclose automated derivation of WBS hierarchies or generation of construction schedules directly from BIM models.

[0014] In existing state-of-the-art technologies, creation of a construction schedule remains a complex task requiring the coordination of activities across multiple scope of work such as concrete, steel, drywall, facade, mechanical, electrical, plumbing (MEP), and others. A first step in such scheduling processes typically involves defining a Work Breakdown Structure (WBS), which specifies the construction sequence using location-based identifiers such as building, phase, level, and area. However, WBS creation in such systems is largely manual and prone to human error, with planners often relying on 2D drawings as the primary basis for defining activities and sequencing.

[0015] In conventional practice, a construction planner typically reviews 2D drawings and manually traverses each element in order to generate an appropriate Work Breakdown Structure (WBS). This approach is not only time-consuming and error-prone, but also suffers from several inherent limitations. Among these are the lack of data consistency across different drawings, the absence of critical quantitative information such as material volumes or areas, and the inability to capture metadata associated with specific building elements.

[0016] Competitive tools in the market likewise rely heavily on manual processes, offering limited automation for WBS creation. The available user interfaces are often complex and require substantial expertise in Building Information Modelling (BIM), thereby restricting usability to highly skilled personnel. Furthermore, there is a lack of seamless integration with model hosting and document management platforms, resulting in fragmented workflows.

[0017] As a result, most conventionally available systems continue to generate construction schedules on the basis of 2D drawings, with such schedules being manually created in advance by the construction planner, making the process tedious, resource-intensive, and susceptible to human error.

[0018] Accordingly, there is a need for a system that automatically generate a Work Breakdown Structure (WBS) directly from Building Information Modeling (BIM) data, and further create a corresponding construction schedule in an automated and consistent manner.

The appearances of the phrase “in one embodiment” in various places in the specification are not necessarily all referring to the same embodiment.

[0038] References in the specification to “preferred embodiment” means that a particular feature, structure, characteristic, or function described in detail thereby omitting known constructions and functions for clear description of the present invention.

[0039] The foregoing description of specific embodiments of the present invention has been presented for purposes of illustration and description. They are not intended to be exhaustive or to limit the present invention to the precise forms disclosed and obviously many modifications and variations are possible in light of the above teaching.

[0040] Referring to FIG.1, a system for generating work breakdown structure based on building information modeling 100 hereinafter referred to as the system 100 is described. In the present embodiment, the system 100 is a web-based application however, the type of application varies in other embodiments of the present invention. The system 100 is accessed through a plurality of electronic devices 115 for example a laptop, computers, handheld devices or the like.

[0041] These devices 115 may include, but are not limited to, personal computers (PCs), laptops, tablet computers, smartphones, personal digital assistants (PDAs), or other Internet-enabled computing devices. In exemplary embodiments, the devices 115 may be respectively denoted as 115-1, 115-2, ... 115-n and are collectively referred to herein as user devices 115.

[0042] The system 100 is accessed by individuals i.e., a first user 105, through the electronic devices 115 and preferably through the internet 120. In context of the present invention, the first users 105 are the individuals that access the system 100 for receiving, creating a planning schedule for the created work breakdown structure. The first user 105 accesses the system 100 through the browser and provides a plurality of digital object 125 to the system 100 for generating an output data 130. However, the system 100 may be standalone, locally hosted in other embodiments of the present invention.

[0043] The system 100 is configured for processing the plurality of digital object 125 received from the first user 105 on a server 110. The system 100 is connected with the server 110 for processing and accessing data. The server 110 is preferably hosted on a cloud computing server or an equivalent medium for remotely accessing, processing the data through the internet. However, the mode of hosting the server 110 varies in other embodiments of the present invention. The server 110 serves as the central processing unit of the system 100 and is configured to interface with the devices 115 over one or more communication networks 120. The server 110 includes one or more high-performance processors, volatile and non-volatile memory, and high-capacity storage modules such as RAM, ROM, and hard disk drives. The server 110 may further comprise redundant networking components to ensure high availability and low-latency communication with electronic devices 115. In the present invention, the plurality of digital object 125 includes graphics, 2D drawings, 3D models, activity to model mapping and productivity data.

[0044] The system 100 imports BIM 3D Model by integrating existing 3D model rendering systems. The system 100 integrates an existing 3D model where the system 100 first handles its file formats, processes and optimizes its geometry and materials for the new environment, and then renders using a suitable 3D engine.

[0045] The productivity data received from the plurality of digital object 125 includes data for example, details regarding tons of concrete pour per day per crew or the like and the activities per trade including their sequence. The system 100 is configured to assess and analyze the input received, process the data and generate the Work Breakdown Structure (WBS) activity on the server 110.

[0046] In context of the present invention, a work breakdown structure (WBS) is a hierarchical tool that decomposes the total scope of work into smaller, manageable components or deliverables. The WBS provides a top-down, deliverable-oriented view of a project, starting with the overall project goal and breaking it down into major deliverables, sub-deliverables, and finally, work packages or tasks. The primary purpose of a WBS is to clarify scope, assign responsibilities, facilitate planning, and serve as a foundation for tracking costs, schedules, and progress throughout the project lifecycle.

[0047] The WBS defines the total project scope by translating high-level objectives into actionable parts. A WBS serves as the basis for creating schedules, estimating costs, and allocating resources effectively. The WBS clarifies who is responsible for each task, improving accountability and avoiding duplicated effort. WBS provides a clear framework for monitoring progress, managing scope creep, and controlling costs.

[0048] The WBS serves as a visual communication tool for project teams, ensuring everyone understands the project's structure and their roles. The system 100 is configured to generate the work breakdown structure for each selected component or group of components on the server 110. The system 100 receives the plurality of digital object 125 from the first user 105 that includes the details of the underconstruction site.

[0049] Referring to FIG.2, the system for generating work breakdown structure based on building information modeling 100 is described. The system 100 includes a user interface unit 205, a processing unit 210 and a database 215. The processing unit 210 bidirectionally communicates with the user interface unit 205 and the database 215.

[0050] The user interface unit 205 includes a login module 220, an authentication module 225, an input module 230, a dashboard 236, a payment module 237 and an output module 235. The processing unit 210 includes a controller 240, a first module 245, a second module 250, a third module 255, a fourth module 260, a fifth module 265, a processor 270, a sixth module 275 and a seventh module 280. It is to be noted that the processing unit 210 is positioned inside the server 110.

[0051] The input module 230 is configured to receive the plurality of digital object 125 from the users 105. The input module 230 receives the plurality of digital object 125 from the users 105 and stores the data in the database 215 through the processing unit 210. The output module 235 is configured to display the report i.e., an output data 130 generated from the system 100. In this preferred embodiment, the output module 235 generates the output data 135 in the form of pdf file, excel file or the like and sends to the users 105.

[0052] However, the file format varies in other embodiments of the present invention. The dashboard 236 displays all the contents of the system 100 after the users 105 logs into the system 100. The payment module 237 is configured to securely receive the payment to the system 100 and provides secure medium for the users 105 to transfer the funds.

[0053] The user interface unit 205 presents a responsive interface accessible through both web-based platforms and native mobile applications Android and iOS. The user interface unit 205 incudes a login module 220 that receives credentials from the registered users and validates with the data stored in the database 215. A database 215 includes a memory 218 (not shown) within the server 110 for storing computer-readable instructions, data structures, program modules, and other necessary data to support the operation of the system 100.

[0054] Additionally, a database 215 is provided to store user profiles, project- related data, and other information essential to the system’s functioning. The database 215 offers dedicated, global storage for each individual user 105 for organizing all associated resources, documents, and data in a structured and accessible manner to eliminate confusion and improve data management efficiency.

[0055] The login module 220 allows the registered users to log in to the system 100. The new users are registered based on some registration parameter and are registered in the system 100. The registration parameters include the details for example “name, age, gender, location of device, email id, mobile number”.

[0056] The data received from the users 105 is stored in the database 215. In accordance with the present invention, the users 105 may log in with device 115 through their social media account or their existing email IDs. In the present invention, the users 105, may reset the forgotten password by receiving new password on the registered email ID or mobile number, message verification, telephonic verification, or the like.

[0057] The authentication module 225, authenticates the registered users in the system 100. The authentication module 225 communicates with the controller 240 and accesses the registered user data and accordingly authenticates the users 105 in the system 100. The controller 240 is configured to process the data received from the input module 230. The controller 240 supervises the function of the processing unit 210 and communicates data to and from each of the module to one another. The processor 270 processes the data as received from the controller 240, produces output and sends back to the controller 240.

[0058] In alternative embodiments, the controller 240 may operate on a rendering engine such as Unreal Engine, Unity, Enscape, Twinmotion, Lumion, V-Ray or the like for standalone processing. In such embodiments the controller 240 receives the prepared geometry, materials, and lighting and then generates real-time visualization for walkthroughs, VR, high-quality stills or videos and analytical visualizations such as energy, daylighting, thermal performance or the like. In such embodiments, it is to be noted that the users 105 navigate interactively with the rendered buildings or generate static outputs such as rendered images, animations, flythroughs.

[0059] In other embodiments of the present invention, the controller 240 allows BIM-data-rich visualization such that a user 105 may click a door or wall in the render and still access its BIM properties e.g., fire rating, manufacturer or the like. In such alternative embodiments, the controller 240 converts BIM parametric objects into 3D meshes, maps materials, applies lighting, and renders via a graphics engine, while optionally keeping BIM metadata attached for interactive or analytical use. In the alternative embodiments, the controller 240 of the first module 245 stores the identified components along with the label data inside the database 215.

[0060] The first module 245 i.e., a building selection module is configured to identify the plurality of building from a provided input BIM model and the plurality of digital objects 125. The first module 245 is configured to identify and select building for rendering the work breakdown structure. The first module 245 facilitates the user 105 to select specific components of a building for rendering work breakdown structure. The first module 245 also is configured to tag the components of the building with a predefined code and definition that is fetched from the database 215.

[0061] The first module 245 includes BIM models that contains both geometric data such as shapes, dimensions, spatial relationships and semantic data such as materials, load-bearing info, fire ratings, HVAC data, or the like. The first module 245 includes a data extraction layer for rendering a building from the BIM file often IFC, RVT, or similar that contains parametric objects such as walls, windows, floors, rather than simple meshes. The first module 245 is configured to interpret the BIM schema to extract geometry of each building component surfaces, solids, further metadata such as materials, textures, colours, lighting properties, hierarchy such as how walls relate to rooms, floors, zones.

[0062] In an alternative embodiment, the first module 245 is configured for geometry conversion such that BIM elements are converted into a renderable 3D mesh triangles or polygons. Further, the first module 245 is configured with complex parametric objects such as curved facades or window assemblies that are tessellated into polygons so the graphics engine processes them. The first module 245 is further configured to apply the LOD (Level of Detail) for example, simplified meshes for fast navigation, detailed ones for close-up renders. Further, in the first module 245 the BIM metadata includes material libraries that is glass, concrete, steel or the like. The materials are translated into rendering shaders that diffuse maps for colour.

[0063] In accordance with the present invention, the second module 250 includes parametric rules set for identifying sub-structure and super structure based on level information present in the plurality of digital objects 125. Further, the parametric rules set include identifying levels based on level information present in the plurality of digital objects 125. Further, the parametric rules set include identifying interior work phase based on interior information present in the plurality of digital object 125.

[0064] The second module 250 i.e., a work phase identifier is configured to receive the data from the first module 245. The second module 250 is configured to process the data received from the first module 245 on the processor 270. The second module 250 is configured to identify the work phases such as sub-structure i.e., the foundation level structure; the super structure i.e., the upper structure of the particular building; the interior i.e. the interior walls, doors, and the like of the particular building. The substructure mainly includes foundations, basements, retaining walls, or the like and the superstructure includes columns, beams, slabs, walls, roofs, or the like that are identified, selected and tagged automatically or manually.

[0065] The second module 250 divides the building data into two or more particular structures through automation tools however, the automation tools vary in other embodiments of the present invention. The second module 250 is also configured to identify individual parameter of the plurality of digital objects 125 for generating work breakdown structure.

[0066] In context of the present invention, the identified sub-structure and superstructure are stored in the database 215 and are referred to generate the work breakdown structure in the third module 255. The third module 255 is configured with levels that are identified from drawings, or parametric rules, then auto -generated using scripts or parametric families. The third module 255 is configured to act as a support for placing all building elements, and automation ensures that changes cascade through the model instantly. In the third module 255 the different levels of the 3D model are marked with different colors so as to easily identify different levels of a particular building.

[0067] It is to be noted that the levels of a building include for example floors, parking, ground floordevel, basement floor / lcvcl, parking floordevel, or the like. The third module 255 is configured to mark the different levels through automation tools however, the tools vary in other embodiments of the present invention. The third module 255 is configured with automation tools to identify levels from different sources, with architectural drawings or CAD imports tools detect floor lines or elevations and the plurality digital objects 125.

[0068] In an alternative embodiment, the third module 255 is configured with project parameters such that the user 105 specifies floor-to-floor heights for example 3.3m until roof or the like. The third module 255 generates plurality of levels either automatically or manually. In the third module 255 any change in floor- to-floor height updates are all related in geometry. The marked data received from the third module 255 is received inside the database 215.

[0069] The fourth module 260 i.e., a selection module is configured to provide selection of individual as well as group of components as per the user requirement. In this present embodiment, through the fourth module 260 the users 105 draw the desired shape i.e., rectangle or polygon however, the shape varies in other embodiments of the present invention. In the fourth module 260 the user 105 is able to edit the area, select the 3D data in tabular and displays the code and name of the selected components.

[0070] In context of the present invention, the fourth module 260 is configured to use filters and data to select specific components. Further the fourth module 260 is configured with the selection sets allow grouping by type, family, or parameter. In another embodiment of the present invention, the fourth module 260 may automate identification using rules. In another embodiment, the model parametric data may be used along with the selection criteria tool to filter elements by type, layer, or property. In another embodiment, scripting via GDL (Geometric Description Language) may automate component recognition.

[0071] In the fourth module 260 the automation tools are used to identify the selected components of a building. In the selected area of the building the components, levels, work phases are displayed. In the fourth module 265, the user 105 selects a particular area and the fourth module 265 is configured to display user selection data such as a code, a name, mode of selection, selected markup type, number of levels selected along with the displayed color.

[0072] Similarly, the markup type refers to a selection shape drawn by the user in this embodiment the selection shapes are rectangle and polygon however, the shapes vary in other embodiments of the present invention. Further, the selected color refers to the color of the structure for example, blue color for sub-structure, yellow color for super structure or the like. The selected data is further stored and forwarded to the fifth module 265. Further, in the fourth module 260, the element is broken down to any shape i.e. smallest fragments using fragmentation technique whose function is provided by forge viewer. In this fourth module 260 the techniques such as Delaunay’s triangulation method are selected for building components for example slabs, walls, foundations and are extracted from BIM to simulate, analyze, or schedule them that may require geometric discretization.

[0073] In accordance with the present invention a preferred process of marking an area and tagging components within the boundaries of the marked area is discussed. In an initial step, the user may mark area that is polygonal in shape either on 2D or 3D orientation. In this step, all the elements inside the marked area are identified using predefined techniques such as Delaunay’s triangulation. For example, in one instance the user selects a partial area of the component, then only a part of the component within that area is tagged and the part of the component outside that area is not tagged.

[0074] Accordingly, the fifth module 265 is configured to receive data from the fourth module 260 through the controller 240 and map a user defined activities to a selected portion of data. In context of the present invention, the fifth module 265 is configured to display the activities linked. The fifth module 265 displays the activity name such as install piles or caissons, install pile caps, grade beams or the like. Further, the fifth module 265 displays the code of activity that is preferably user defined, unit of measurement, productivity data, crew size required and the like. The fifth module 265 is configured to assign activities on the components as per the user requirement. In accordance with the present invention, the fifth module 265 is configured with condition sets that provide mapping of activities to BIM model elements based on model elements parameters. For example, in this one instance, activity is foundation pour that gets mapped to foundation elements such as footings, pile caps, isolated foundation, continuous foundation or the like. In accordance with the present invention, the sixth module 275 is configured to generate a WBS. In context of the present invention, the sixth module 275 compiles the first to fifth modules (245- 265) and breaks the project into manageable tasks, phases, or packages.

[0075] In context of the present invention, the seventh module 280 is configured such that the WBS generated from the sixth module 275 is utilized to create construction schedule that is generated using critical path method such that the activities are linked to the BIM model elements. The seventh module 280 is configured to produce the output data 130 through the output module 235. In the seventh module 280 the WBS are linked to CPM such as duration estimates, predecessor’s dependencies, resources or the like.

[0076] The seventh module 280 is configured to calculate earliest and latest start or finish times and identifies the critical path longest path through the project. The seventh module 280 utilizes Gantt chart generation through CPM dates that are calculated through activities are plotted on a timeline bars. The Gantt chart visually aligns WBS hierarchy with CPM logic.

[0077] The output data 130 includes an ID such as WBSID that includes a plurality of parameters such as a super structure, sub structure, productivity, crew size, duration and quantity. The seventh module 280 is further configured to generate a report based on the processed data. The seventh module 280 generates a report that provides the estimated material cost, labor, duration, quantity, structure id and the like.
