Level of Detail & Development (LOD) in BIM Modeling Explained

What is Level Of Detail – LOD BIM?

Building Information Modelling (BIM) is a concept that refers to the process of producing and managing digital information about a built asset such as a building, bridge, highway, or tunnel. It gives a complete idea of the AEC project including the technical and non-technical aspects of the project. BIM has always played a vital role in the process of construction management and designing. 

A model of a structure when represented digitally, it represents certain level of detail of a project. The overall condition of project’s information model at a specific stage in its design process is referred to as BIM Level of Detail / BIM Level of Development. 

Revit BIM LOD comprises not just graphical elements, but also the data linked with them. The Revit BIM model should evolve over time, starting with a rough sketch and progressing to the record drawings and as-builts. 

As one of the leading design-build firms in USA, Tejjy delivers detailed coordinated building construction models in Autodesk Revit with required BIM LOD stages, equivalent to comprehensive Gantt charts that help you to monitor projected progress v/s actual progress of the project.

Backed by an in-house team of expert BIM engineers, we have successfully delivered precise Revit LOD BIM models to our clients with specified Level of Detail and Level of Development, ranging from BIM LOD 100 to LOD 500. Tejjy’s Revit BIM services have assisted clients to boost their projects in terms of cost and time with organized project schedule and overall management of the construction project. 

BIM Level Of Details – LOD 100, 200, 300, 350, 400, 500

The American Institute of Architects (AIA) have categorized Revit BIM LOD into six different categories in LOD specification – 2015. Given below are various Levels of Detail. 

LOD 100

The Model Element may be graphically represented in the Model with a symbol or other generic representation, but does not satisfy the requirements for LOD 200. Information related to the Model Element (i.e. cost per square foot, tonnage of HVAC, etc.) can be derived from other Model Elements. 

LOD 200

The Model Element is graphically represented within the Model as a generic system, object, or assembly with approximate quantities, size, shape, location, and orientation. Non-graphic information may also be attached to the Model Element.  

LOD 300

The Model Element is graphically represented within the Model as a specific system, object or assembly in terms of quantity, size, shape, location, and orientation. Non-graphic information may also be attached to the Model Element.  

LOD 350 

The Model Element is graphically represented within the Model as a specific system, object, or assembly in terms of quantity, size, shape, location, orientation, and interfaces with other building systems. Non-graphic information may also be attached to the Model Element.  

LOD 400

The Model Element is graphically represented within the Model as a specific system, object or assembly in terms of size, shape, location, quantity, and orientation with detailing, fabrication, assembly, and installation information. Non-graphic information may also be attached to the Model Element.  

LOD 500

The Model Element is a field verified representation in terms of size, shape, location, quantity, and orientation. Non-graphic information may also be attached to the Model Elements. 

BIM Level of Development specification defines different levels of BIM modeling. Construction professionals can design the models according to the requirements of the project or the requirements of the clients respectively. 

BIM Level of Detail – Standards

Let us understand various levels of LOD BIM standards with an example of light fixture, as mentioned in the BIM LOD specifications. 

Example: – 

Level of Detail / Level of Development  Specifications 
100  Cost/sf attached to floor slabs 
200  Light fixture, generic/approximate size/shape/location 
300  Design specified 2×4 troffer, specific size/shape/location 
350  Actual model, Lightolier DPA2G12LS232, specific size/shape/location 
400  As 350, plus special mounting details, as in a decorative soffit 

(Source – BIM LOD specification 2019 pdf)  

Importance of implementing BIM Level of Details in AEC projects 

As we live in a modern world where everything is digital and all key projects implement latest technologies such as BIM modeling, it might be difficult for designers to get other teams to comprehend the project requirements. Most of the time, dealing with a BIM model presents a unique issue because different people have varied definitions of what constitutes “complete.”  

BIM LOD establishes a common definition of what constitutes project completion, hence reducing the likelihood of inconsistencies related with project completion. Because of the use of LOD BIM, teams of construction professionals working in diverse disciplines may communicate with one another more effectively and with greater clarity and transperancy.

The employment of innovative techniques and technologies in LOD design improves the clarity of the final product, as a result.  


LOD establishes a consistent definition of project conclusion and removes the possibility of project complexities and disputes. By implementing LOD in Revit BIM models, teams from various disciplines can interact with each other resulting in more clarity and effective decisions. BIM LOD improves design clarity by utilizing latest techniques and technologies. 

Level of Detail or LOD BIM aids in communicating the clarity and dependability of Building Information Models at various stages of the construction project. In brief, it aids in defining the deliverables and milestones of a project. 

BIM LOD has permitted the segmentation of the entire BIM modelling & design process into several levels. It has aided in distribution of task and has made work easier for Engineers, Modelers, Architects, and construction professionals working on project.

⭐10 Most Common Myths About BIM Debunked| Busted in 2022

debunking the most common myths about bim

Common Myths About BIM

Building Information Modelling is becoming an inseparable part of the daily lives of those who belongs to Architectural Engineering Construction and Operation (AECO) industry but remains shrouded in mystery to many stakeholders involved. 

Before elaborating the some common myths about BIM and truth let’s find out “What is BIM?” first. 

The entire process of creating and managing information for a built object is known as Building Information Modeling (BIM). BIM generates intelligent cloud-based model integrating multi-disciplinary structured data to build a digital visualization of an object throughout its lifecycle from conceptual and designing stage to construction and operations. 

The notion of BIM has been around since the 1970s, but it was only in the early 2000s that it became a widely accepted word. In the current scenario, BIM is being adopted by leading countries throughout the world.

The government is making use of BIM mandatory in construction projects since it has been beneficial in streamlining various construction processes and resulting in increased production.  

🏠 Debunking or Busted Myths About BIM

It is important for every company that belongs to the AEC industry to be aware of these common myths about BIM implementation. It is reasonable to have some hesitations about any change in the workplace specifically while implementing something new.

BIM offers end numbers of benefits that far exceed its drawbacks. BIM facilitates a very useful procedure that benefits all of the project stakeholders. It enables all AEC professionals to collaborate by providing a comprehensive view of the entire project. 

🏠 Most Common Myths About BIM Technology Busted

Despite the advantages, a few common myths have made people cautious to implement and execute BIM in their projects.

Myth 1. BIM Is Just a Type of Software

Truth – One of the biggest misconceptions about BIM is it’s just a software. Whereas BIM is not at all a software package it’s a mindset, a process flow.

For BIM implementation you need to consider people, methodology and technology to re-design traditional work process to utilise the full benefit of digital collaborative construction process. 

Myth 2. BIM Is Limited to 3D Modeling

Truth – BIM is not just generating 3 dimensional visual representation of physical and functional elements of a building. It’s far more than that. 3D Modeling is just one of the functionalities of BIM that allows users to visualize the appearance of the building design.

BIM not only produces data-rich 3D models but enables collaborative work processes involving AEC professionals in a building project. The process enables the production of graphical and non-graphical digital datasets. 

Myth 3. BIM Implementation – It’s Complicated

TruthLikewise, in other advanced technologies there exist a misconception “BIM implementation is a too complex process” but it’s actually not. There is a requirement for proper training and knowledge which can be gained through online courses, online tutorial videos and other free available resources. 

There are multiple BIM Companies in USA like Tejjy Inc. that provide extensive training and short training along with monthly BIM to break down the understanding issues. Mostly these trainings are fully optimized with the government regulations and industry standards.

Before BIM implementation, we do research on the project specification and industry-standard then plan accordingly. Hence, BIM implementation is not complex but needed learning and research.  

Myth 4. BIM (Building Information Modeling) Is Expensive

Truth – Most people are apprehensive about deploying BIM because they believe it will be costly. When we adopt any kind of change in working processes, there will surely be an early expense as adopting every new technology takes, but this will be offset by long-term efficiency and rewards.

The efficiency of BIM is dependent on accurate data representation and the ability to make data-driven decisions. It is important to recognize that process efficiency reduces overall risk and saves a significant amount of money. 

Myth 5. BIM Is More Suitable for Big and Complicated Project 

Truth – BIM is commonly used in large projects only because it allows better project management as compared to traditional construction methods – This is not completely true. Big projects are obviously more complicated and time-consuming but the issue of every construction project tends to be the same.

BIM improves design cost calculation efficiency and saves time while estimating and analyzing project costs. BIM is beneficial to everyone, irrespective of the size of the project. Whether it’s a public or private project, the team of Tejjy Inc. utilizes the benefits of BIM to execute it efficiently. 

Myth 6. BIM Is Beneficial Only to Designers and Constructors

Truth – Many people assume that BIM is only valuable during the design and construction phases, however this is not the case. BIM benefits all project stakeholders involved into the project lifecycle. 

The process is efficiently taking care of everything at every stage of the construction process. Hence helping Designers, Constructors, Facility Managers, Estimators, Modelers and other project stakeholders to have complete overview of the project progression and execution collaboratively. It is also helpful for renovations, retrofits, destruction and refurbishment. 

Myth 7. BIM Implementation Require a New Team

Truth – Many people assume that BIM deployment requires a new set of skills and a new team. This is not absolutely the case. BIM implementation training can be provided to the existing team.

People are hesitant because they have developed myths about BIM technology in their mind that BIM has numerous benefits but is difficult to execute, which is not the case. BIM Service Provider Companies that have successfully incorporated BIM, trained their existing engineers, team members and project managers to incorporate BIM into their current workflow.

Moreover, BIM aids the project’s workflow by streamlining it but tendency to accept changes in the workplace makes the process difficult. BIM is simple to adopt, and it has resulted in greater project efficiency. 

Myth 8. BIM is Just a Trend 

Truth – In the construction business, BIM is gaining popularity, globally since the 2000s. BIM has been adopted by many of the top countries worldwide and is now mandatory for all public projects. The global construction industry has recognized the value of BIM and how it is helping in design coordination, work collaboratively, waste elimination, and saving cost consumption.

The notion that BIM is merely a passing fad is a myth. BIM has made a big change in the workflow and proper utilization of technology in the AEC industry as mankind has improved its standards to the digital world. Companies gaining more work efficiency and competitive edge adopting BIM. Hence it is not just a fad but it is a natural evolution of the Architectural, Engineering and Construction industry 

Myth 9. BIM is More Time Consuming 

Truth – Undoubtedly, any procedure that entails new ways of working will take time to scope, implement, and integrate. Careful and effective planning helps in reducing the impact of picking the proper pilot project and ensuring adequate time and resources to get up to speed. 

This helps in building momentum. Longer run, you begin to reap the rewards sooner rather than later, with gains outweighing the initial expenditure. In comparison to more traditional methods of project planning and resourcing, a BIM approach often frontloads the generation of project-related information and assets, which might take some time to get used to.

With a variety of training and accessible tools even the busiest firm manages to get up to speed.  

Myth 10. BIM Impacts Productivity 

Truth – People who have misconception about BIM consumes more time assumes that BIM has a negative impact on construction productivity. We can’t expect any drastic changes in the process to produce immediate outcomes.

BIM, on the other hand, pays off in the long run when given the proper amount of time, planning and investment resources. It not only pays off the investment, but it also streamlines several procedures, resulting in increased efficiency. 

🏠 What is not BIM? 

As BIM becomes more important and relevant in the marketplace, activities that may be termed as BIM wash begin to appear. Some BIM-enhanced products are already available on the market.

This is why it’s critical to address a few points that can aid in determining “what is not BIM”. 

3D models which is only the 3D graphical visualization of an object or, a building is “not BIM” but data-rich intelligent 3D models are considered as BIM 

Solutions that emulate 3-dimensional models by using multiple 2D reference drawings or documents do not allow automatic quantity extraction, updates, or even simulations and analysis, hence it can’t be considered as BIM 

3D Models that are developed not using parametric and smart object are considered as “Not BIM”. 

Solutions that are incapable of generating automatic updates like Automatic Clash detection, Report generation, etc. 

3D tools and process that are not managing integrated database are “Not BIM”. 

🏠 Why Do People Not Use BIM? 

Despite the fact that BIM is a widely established technology in the building construction sector, many small businesses are hesitant to adopt it. They believe it is only relevant for large construction companies, high-end architects, government projects, or environmental organizations.

The biggest issue that this advanced technology faces is a lack of proper understanding and misconceptions about it. According to a survey done by the National Building Specification (NBS), the construction industry faces five major challenges when implementing BIM technologies. 

BIM demand from client-side is very less 

No or, minimal requirement of BIM in typical projects 

Less advantage for companies who are working on only small project 

BIM implementation charges more for small companies in AEC industry 

Lack of knowledge on BIM 

🏠 What Are the Disadvantages of BIM? 

BIM, or building information modelling, is a useful tool for conceptualizing, planning, and designing structures of any scale and complexity. Though there are a bunch of advantages we can utilize with BIM, there exists few disadvantages of BIM too in the AEC industry. 

Modelling Software packages required to implement BIM 

Additional investment required for training old staffs or, to hire new BIM professional  

Requirement of initial document upload for further project execution 

Incompatibility with other project stakeholders, who are not aware about the BIM process 

Lack of usability knowledge of BIM for Facility management after the handover stage 

🏠 What Are the 4 Stages of BIM? 

BIM (Building Information Modeling) is a collaborative system that facilitates industry experts in the design, model, delivery, and maintenance of assets over their entire existence. BIM is a system for defining the characteristics of a building facility that allows stakeholders to share information from conceptual stage to demolition. 

Different levels of participation are guaranteed by the gradual and recognizable milestones, which are characterized as different levels. These levels, which range from 0 to 3 and beyond, are as explained below: 

BIM Level 0: Level 0 is the simplest and traditional process which actually means No Collaboration. 2D CAD drafting is only utilized to execute a project and generates Production Information either in electronic form or, on paper. 

BIM Level 1: Both 3D CAD and 2D drawing are used in Level 1 BIM. While 3D CAD is utilized for conceptual designs, 2D CAD is used to create statutory approval papers and Production Information.

At this level, data is shared electronically through a common data environment (CDE) managed by contractors. Everyone develops and controls their own data hence, there exists minimal collaboration among the stakeholders at this level. 

BIM Level 2: Level 2 BIM is used extensively for public-sector projects. This level encourages collaboration by providing each stakeholder with their own 3D CAD model. This level is distinguished by collaborative functioning, and it necessitates efficient project-related information submission as well as smooth coordination across all stakeholders. 

All project members work on their own local 3D CAD models, and data is shared using a standard file format. Organizations can use such a technology to construct a federated BIM model by combining external data with their own model.  

BIM Level 3: The scope of Level 3 has not yet fully defined, but it offers broader collaboration between all stakeholders through a work-shared model in a digital common date environment (CDE). It is also known as ‘Open BIM.’

The Level 3 idea allows all participants to work on the same model at the same time, eliminating the possibility of contradictory information. Level 3 suggests using an integrated system based on open standards like as IFC, with all project data stored on a single server.

BIM consultants use intelligent 3D BIM models with various inputs such as Contract Documents, Design Documentation, Specification Sheet and Equipment Submittal for BIM MEP coordination. Competent BIM engineers follow SMACNA standards and other local codes as applicable to new building construction or renovation. MEP consultants validate the design for constructability review, performance as well as maintenance at the pre-construction stage. Accurate MEP BIM coordination helps to decrease RFIs responses and resolve clashes through re-routing ducts, modifying elevations and resizing ducts. As a result of which, the final MEP model becomes free of clashes and other design errors. A strict quality control process is followed by BIM companies offering MEP BIM services for documenting client standards and preference. Implementing BIM MEP services facilitates proper MEP coordination and accurate MEP shop drawing creation, thus reducing rework. Several MEP design-build projects produce comprehensive shop drawings for installation and spool drawings for pre-fabrication.

What is the Role of BIM Modeling Services in MEP


Let’s take a look at the details of MEP BIM services?

What are MEP BIM services?

MEP BIM Services involve a technique of creating an informative 3D model with mechanical, electrical and plumbing components of the building. MEP architecture of a building is essential in ensuring building performance at any stage of the product lifecycle.

What is MEP modeling?

MEP modeling or MEPF modeling includes the mechanical, electrical, plumbing and fire protection services to define the various spaces and zones in a building model. A perfect MEP model created through Revit BIM helps to minimize project delays, reduce project wastage and enhance cost savings for the construction.

What is Revit used for MEP?

Revit family constitutes to be the vital building block of MEP (mechanical, electrical and plumbing) designs. Revit MEP software facilitates in executing 3d modeling and MEP BIM Services, generating intelligent models for HVAC, Electrical and Plumbing services of a building.

What are the Deliverables from BIM Modeling Services in MEP?

  1. 3D Modeling with Constructability Review
  2. Mechanical & Plumbing Design Validation
  3. Clash Detection & MEP BIM Coordination
  4. MEP Shop Drawings
  5. Quantity Take-off/Bill of Materials (BOQ)
  1. 3D Modeling with Constructability Review –  MEP BIM modelers create HVAC Sheet Metal Modeling for mechanical services. 3d HVAC model gets prepared by the BIM consultants, according to the specifications of the engineering documents through a range of inputs such as design and contract document (including IFC drawings, Construction Documentation set, etc.). Then the model is coordinated with other architectural, structural and MEP services. Top MEP consultants augment the HVAC models with hangers, seismic restrainers as well as other information from various trades. The final model helps in smooth MEP coordination, decreasing field installation time, cost and wastage. Further, from the MEP model, fabrication and spool drawings are created in Revit, Navisworks, etc. for accurate on-site prefabrication and modularization.


  1. Mechanical & Plumbing Design Validation

  1. Clash detection & MEP BIM Coordination

MEP Consultants provide comprehensive clash detection facilitating building contractors to obtain all required information for detecting and resolving interference amongst building systems. The coordination drawings provided by competent MEP engineers help to resolve issues during the pre-construction stage, saving construction cost and time. Some of the MEP Coordination drawings derived from the 3d BIM Model show work details of various services and clashes with structure, ceilings, frames, equipment, partition, MEP services, etc.

  1. MEP Shop Drawings

 BIM engineers produce comprehensive MEP shop drawings with various elevations, dimensions and annotations.  Shop drawings and installation drawings derived from the 3D BIM model enable workshop fabrication and on-site installation.

Some of the MEP Shop Drawings include:

  • Installation Drawings – MEP BIM consultants produce installation drawings from the BIM model, including HVAC, piping, fire protection and medical gases. The drawings help the building contractors to plan, execute and install MEP services. Many of the MEP plans are produced by referring to the architectural walls and structural columns for easy location of the mechanical members.
  • Block-out Drawings – Block-out drawings are preferred for understanding the significance of illustrations such as pouring concrete on-site. These drawings are an important part of MEP services and are aligned to architectural grids. BIM modelers keep necessary clearance for block-out as per contract documents.
  • Sleeve Insert & Hanger Drawings – The MEP drawings also include the sleeve, insert and hanger drawings, produced from the BIM model to help the construction team in making the right MEP installation.
  • Spool Drawings – The spool drawings guide plumbers in understanding what they are encountering during off-site/on-site pre-fabrication. Segmented spool drawings are created following the contractor’s pr-fabricating standards.
  • Equipment Pad Layout – Equipment Pad Layouts help accurate installation of HVAC equipment from submittals in an apt location, coordinating accessibility.


5. Quantity Take-off/Bill of Materials (BOQ)

3D BIM model helps to produce accurate material quantities and update that automatically with changes. BIM MEP modelers create comprehensive material measurement in construction project about ducts, equipment, fittings, hangers, grills, diffusers, etc. Quantity Take-Off reports get exported to a database for detailed analysis. MEP BIM Coordination experts use BOQ services for accurate 5d cost estimation, material procurement and for saving inventory costs.

Autodesk Revit & Architectural BIM Modeling

Today, architects are using Autodesk Revit BIM Software Solution for exploring, validating & conveying building designs. This helps them to detect constructability issues at the pre-construction stage, saving time. Envisaging how the residents & visitors will interact with a building entails a vital part of the design process – be it related to the casting of shadow on an adjacent area, brick facade matching with other buildings, overcrowded lobby area, or adequate daylight to monitoring to a passage.  All these can be accurately visualized with the help of Autodesk Revit BIM technology before the building design becomes real. BIM Modeling services provides the ability to visualize building performance before construction.

Autodesk Revit & Architectural BIM Modeling

Benefits of Architectural BIM Modeling through Revit:

  • Coordination: Communication gets streamlined with 3D BIM visualization amongst all AEC project stakeholders for quick decision making during the design & the pre-construction stages.
  • Promotional Tool: Architectural 3D visualization through BIM empowers prospective investors, consumers & project owners to comprehend the layout & spatial interrelationships of a building project.
  • Productivity: Accurate and coordinated Construction Document Sets get produced from the 3D BIM modeling services, including all data, graphics, and schedules.
  • Conceptual Cost Estimation: Bill of Materials or Quantity take-offs can be obtained from the Architectural 3D BIM modeling which, when linked to the prevailing rates of materials & construction methods, can facilitate the project stakeholders for preparing cost estimates.
  • Integrated Building Materials: Real-life materials drive comprehensive plan, section, and elevation representations of building components for saving documentation time. The integrated Accurender, Ray Tracing & Real-Time Radiosity Engine for Revit uses similar materials, saving time & effort while producing visualizations.

Revit BIM Architectural Services

  1. Architectural Design Development through Revit BIM: Architects use Revit BIM for developing their architectural design.  Team of BIM Engineers interacts with the architects for understanding the architectural design-intent and thus provides value-added support with the design evolution from the conceptual or the schematic stage to the construction stage. To execute the architectural drawings and creating an integrated architectural 3D Model, BIM Modelers work with Conceptual Drawings, Conceptual Models and Hand Sketches as inputs. 

3 Main Stages of Architectural Design Development in Revit BIM include:

  1. Architectural Conceptual Design: Conceptual designing is the initial phase of architectural design, in which the architectural drawings or the solid models are the tools for providing an interpretation of the proposed system. The description gives an integrated idea and conceptualization of the behaviors of the proposed system so that it is comprehensible by the clients in their desired way. The design stage is related to the LOD 100 Revit Model, including the elements defined as Masses and used for preliminary studies, like Conceptual Design & Project Phasing.

In the Revit software platform, every design option belongs to a design option set, which is a method of structuring the design into clusters for assisting architectural workflow. For instance, an architectural project may have design options for an exterior façade, bathroom configuration and ceiling plan. Revit facilitates the architect to produce various sets for design options.

2. Architectural Detailed Design: This stage follows the conceptual or schematic design where the Autodesk Revit & Architectural BIM Modeling are executed in greater detail. The details get reflected in the model, matching with the LOD 300 Revit model. This provides the client with drafted to-scale drawings, exemplifying how the architectural project would appear after the construction gets over. LOD 300 models comprise of elements where the Generic Components get substituted with completely defined Assemblies. Analysis based on Specific Systems can be accomplished and Quantities based on Materials can be acquired. At LOD 300, the architectural model can be leveraged for Construction Documentation & Shop Drawings creation for Energy Performance, Clash & Cost.

3. Architectural Construction Documentation:

Construction Documentation acts as a bridge between building design & physical construction, encompassing the creation of drawings and specifications stating the comprehensive requirements of the building project. This corresponds to LOD 400 Revit Model with all information of the building including accurate elements in terms of size, shape, location, quantity & orientation with fabrication, assembly & detailed information. During this Level, the Model has non-geometric (3D) information such as the text, notes & 2D details making it to be a complete representation of all the projected building elements. Analysis can also be accomplished at this stage like Energy Performance, Clash Detection as well as Sequencing & Cost. Several sheets are produced at this level including:

  • Floor Plan, Room & Furniture Layouts
  • Building Sections, Partition Details & Interior Elevations
  • Door & Window Schedules
  • Floor Finish & Reflected Ceiling Plans
  • Landscape Plans & Details
  • Quantity Take-Off

Architectural Coordination with Other Building Services:

Coordination among various parts of a building is significant for the building design. The breaks between design disciplines are often a cause for change orders in the field of construction and can get eliminated through early coordination among trades including Architecture, Structure and MEP, thus closing design loopholes.

  • Interior Design for Architecture:

Architects also get the support of Revit BIM for interior design for renovation or new construction. Revit BIM assists the architects to continue the job of Construction Documentation with all detailed sections, creating the schedules of materials & fixtures.

  • Architectural Thermal Analysis of Buildings:

Identifying and benchmarking energy usage across buildings is a significant consideration for architects while designing. This ascertains the prospects for energy efficiency which in turn supports cost savings and enhanced building performance. With the advanced facets of Revit Thermal analysis, one can understand the position of the sun and how it changes to the building being designed throughout a day or different seasons in a year. This helps the architects in visualizing shadows and evaluating building performance in terms of natural light. Solar Study tool in Revit software platform helps the architects to analyze the lighting and heating requirements of the building.

  • Architectural BIM Visualization & Virtual Mock – The design verification process through Revit BIM enables the architect to ensure design as per client expectations. A virtual mock-up of building components with equipment is an operational device for performing this task.
  • Architectural Content Development through Revit BIM

Architects can transform drawings to BIM workflow with Content Development through Revit Families, containing all relevant information about technical specifications like product manufacturer; Omni Class Code, Title as well as Subcategories for helping clients identify the necessary component with ease. Some of the Examples of Autodesk Revit & Architectural BIM Modeling services include:

  • Cabinet, Drawer, Fixture, Furniture
  • Doors, Windows, Specialty Equipment
  • Stairs, Railings, Cart, Desk
  • Caseworks, Sheets, Watches
  • Accessories for Interior Decorations
