Expected Growth of Global 3D Scanning Market from 2021 to 2026

What Is 3D Laser Scanning?

3D Laser scanning, also known as high-definition surveying or reality capture, is a technique that uses laser rays to collect incredibly fine & accurate data about a construction site. A laser beam measures various dimensions of the structure such as, the length, width, and height of the building components, as well as their connection to one another.

The process of scanning uses a specific technology for scanning the objects on a construction project. The technology is known as LiDAR – Light Detection And Ranging.

3D laser scanning has made its mark not only in the Architecture, Engineering and Construction (AEC) industry, but also in various other sectors such as films & media, gaming & technology, medical, manufacturing, automobiles, and many more.

Despite the fact that the technology has taken a little longer to reach the construction field, it is gradually becoming a standard on construction sites all over the world.

The 3D laser scanner creates a point cloud image that accurately replicates the scanned items. Scanners can be used up to a distance of several meters away, depending on the make & model of the 3D scanner. Building Information Modeling (BIM) and Computer Aided Drawing (CAD) systems can then be used to create either 2D CAD drawings or 3D Revit BIM models from the data acquired.

The models and drawings created using the point cloud data assists the professionals of the Architecture, Engineering and Construction (AEC) industry to carry out the construction process effectively, accurately and in a more precise manner.

How do 3D Laser Scanners Work?

3D laser scanning is a technique that uses laser light for scanning the surrounding objects.

But the question is how does 3d scanning work? What is the procedure? Let’s learn about the step-wise procedure of 3D Laser Scanning.

3D laser scanning work process

✍️ Place the equipment at a certain point that is to be scanned.

✍️ Calibrate the camera with respect to the surface.

✍️ Start the scanning process.

✍️ Collection of data in the form of point cloud.

✍️ Transfer the raw data in the software.

✍️ Create a 3D BIM model / as-built model using the point cloud data.

BIM Engineers created an as-built model using a point cloud for the ‘1155 23rd Street Northwest‘ project based in Washington, DC.

Read more about our Case Study of a BIM As-Built Model from Point Cloud for DC Project.

Application of 3D Laser Scanning in Construction Projects

Construction Designing – reality capture is used to prepare complex designs of large-scale construction projects. These designs are in the form either Computer Aided Drawings or Revit BIM models.

Creating as-built Models and Drawings – as-built models and drawings are prepared using the scanned point cloud data. As-builts are generally used for repairs and maintenance purposes of a structure. They represent the actual condition of the structure.

Surveying – High-definition surveying is carried out using laser scanning technology. Various types of laser scanners such as ground scanner, mobile scanner and aerial scanners are used to capture the topography and other such features of the construction site area. High definition surveying is gradually taking over the traditional surveying techniques.

Volumetric Calculation of Construction Materials – Volumetric calculation of construction materials can be calculated using surveying through laser scanning technology.

Renovation and Retrofitting of Structures – Reality capture produces as-builts through the point cloud data. It represents the exact model of the built asset in its present condition. The as-built model of the structure is examined the structure is renovated accordingly.

Different Types of 3D Scanners

There are quite a few types of laser scanners available in the market that are ideal for construction projects. Depending on their operational platforms, they are divided into three major categories. Let us have a look at each one them below in brief.

Terrestrial Laser Scanner – commonly abbreviated as TLS, the terrestrial laser scanner is also known as ground LiDAR. It is usually mounted on a tripod while the scanning operation is commenced.

Terrestrial Laser Scanners have the highest accuracy among all the types of scanners available in the market. It is because the device remains stationary at a position while the scanning operation is going on.

Aerial Laser Scanner – Aerial Laser Scanner (ALS), also known as aerial LiDAR refers to a laser scanning device that is installed on an aircraft and used while the aircraft is flying. It is also known as mobile LiDAR as it can be easily transported from one location to another by means of a mobile ground-based platform such as a vehicle.

The accuracy of aerial scanners is relatively low due to its mobility. They are used for acquiring the point cloud data of the geographical features or topography.

Mobile Laser Scanner – As for Mobile Laser Scanner or MLS, because of the ease with which the movement path can be controlled, the laser scanning device is widely used in 3D city mapping applications as well as in autonomous vehicle sensing systems.

They are relatively smaller in size and lighter in weight so that it can be carried easily from one place to another.

Advantages and Disadvantages of 3D Laser Scanning Technology

There are numerous advantages to utilizing laser scanning on your next project, as listed below. Here’s a look at some of the most important reasons why laser scanning could be beneficial for your projects.

Advantages of 3D Laser Scanning

Construction teams can take planning and detail to a whole new level using laser scanning. This enables scans to be performed and accessed immediately, which improves productivity and reduces rework.

  1. Cost Effectiveness – the process requires lesser duration then the conventional surveying process eliminating the expense incurred by utilization of resources for longer duration.
  2. Saves Time – quicker than the traditional surveying, laser scanning can perform building scans within a couple of minutes.
  3. Accuracy and Precision – the modern day technique is way more accurate & precise as compared to traditional surveying. It is because laser scanning eliminates human errors.
  4. Detailed Documentation – The point cloud data obtained during the 3D scanning process is so detailed that it captures practically every feature of the object being scanned. The likelihood of any omission during the scan is much minimized, and the likelihood of any error is relatively low.
  5. Reduces Manual Labor – utilization of unwanted resources and labor is eliminated by 3D laser scanners which results in cost and time efficacy.
  6. On-site Safety – Construction sites are concerned about the safety of workers and other employees. Portable 3D laser scanners for surveying can take precise measurements from up to several hundred meters away. It helps the workers to keep away from hazardous surroundings and topography, ensuring their safety.

3D Laser Scanning Disadvantages

  1. High Initial Cost – the initial cost of the camera is very high. According to some sources laser scanners can cost anywhere ranging from $20,000 to $150,000.
  2. Lack of Knowledge of the Technology – the technology is still not known to some of the areas and the people there lack the knowledge of laser scanners and laser scanning.
  3. Lack of Trained Professionals in the Industry – due to lack of trained professionals, there is a lack of adoption of laser scanning technology. The professionals of construction industry must be trained through certified laser scanning courses.

It benefits the professionals personally and the Architectural, Engineering and Construction (AEC) industry as well.

How Much Do 3D Laser Scanning Services Cost?

Laser scanning and Revit BIM modeling have become significantly more affordable as a result of recent advancements in scanning technology and scanning software development. Pricing is determined by a variety of factors. It’s understandable that an builder would be concerned about the expense of 3D scanning services if he is planning a big hospital renovation or if he wants to scan the facility for historic preservation purposes.

A variety of factors influence the cost of 3D laser scanning services, with professional laser scanning and modeling services ranging from $2,000 to more than $100,000. ​

The project cost varies depending on the size of the project. As an illustration: Small projects, such as a food restaurant or a gas station, may cost between $2,000 and $3,000 to complete. Medium-sized projects, such as an industrial complex, may cost between $3,000 and $10,000. Huge projects, such as a large manufacturing unit, an entire retail mall, or a hospital campus, may cost in excess of $10,000 to complete successfully.

What Does the Future Hold for 3D Laser Scanning?

The use of static 3D laser scanners and the expertise of skilled surveyors and scanning experts will always be a top priority requirement for construction projects in order to attain precise and high accuracy survey data. Nonetheless, the demand for quick 2D drawings and 3D models that are independent of the environment — whether outside, inside, or under artificial light — is driving the use of mobile scanning technology.

It will be necessary in the future for new hardware scanning devices to integrate with the digital world of BIM and cloud-based processing. A larger range of workflows, including scanners and other reality capture equipment, must be incorporated into order to improve the value of scan data to all parties involved in the process.

Construction professionals and surveyors must be aware of new technologies and cloud-based advancements since they will have a significant impact on cultural and operational changes in the field.

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.  

Conclusion 

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.

Point Cloud to BIM Conversion – A Reality Check

Point Cloud scan to BIM is a 3D model created with laser scanning. Point cloud modeling is widely popular for its precision. As you can extract detailed elements of an object captured in physical space.  This enables accurate modeling,  clash coordination and quantity takeoff (QTO) or Bill of materials (BOQ). Several construction projects in the renovation and the extension stages are using point cloud scan to BIM process for 3d model creation, 3d visualization, animation and quality inspection. Scan to BIM modeling involves the technique of making a digital representation of an existing building condition with its functional and physical attributes. Laser scanners facilitate in obtaining a perfect 3d scan to BIM, which is then imported into the 3D BIM software. Faro scan to BIM process is designed by architects, engineers and general contractors to process 3D laser scan data quickly and accurately. Revit scan to bim is also popular for creating as-built models for refurbishment and renovation.  Scan to BIM revit facilitates creation of as-built BIM model for renovation work of infrastructure asset including tunnels and bridges. In the AEC sector, laser scan to bim best practices are used by the surveyors, owners, architects, engineers and general contractors for their renovation and refurbishment projects.

What are the laser scan to BIM services?

  • 3d Modeling – 3d models are created from laser scan to BIM process for architectural, structural and MEPFP services for the sake of renovation and extension work. The process of scan to BIM modeling enhances transparency, streamlining communication for quick decision making throughout the project lifecycle. High quality revit scan to bim modeling ensures that the Revit components are built intelligently with the practicality of serving the purpose. Parametric Revit families contain a realistic information about performance models, required for executing calculation analysis and construction simulation. Scan to BIM add-in helps to create and validate model from point cloud with automatic recognition and placement of architectural and MEP elements like walls, columns, pipes, ducts, conduits, etc.

Usually, a data rich 3D scan to BIM model includes:

  • Necessary COBie parameters
  • System connection establishment between source & destination of services
  • Modeling of Asset facilities
  • Comprehensive Connector in equipment families
  • Linking COBie extension sheet in the model

 

  • As Built Drawing Preparation – The purpose behind Scan to BIM applications is capturing the actual as-built conditions of buildings. BIM serves as a knowledge repository coordinating building facilities throughout the project lifecycle. As-built drawings from laser scan facilitates planning, elevations and formation of section sheets for architectural, structural and MEP services. The construction drawings serve as a comprehensive reference tool enabling future project planning, through renovation, extension and redevelopment from point cloud scan to bim. As details related to building dimensions, erection, fabrication, material location, elevation, etc. are obtained from as-built drawings, they could be used for resolving disputes regarding insurance claims.

 

  • 4D Construction Scheduling – Implementing scan to BIM Revit software platform, point cloud scan to BIM enables old building renovation for gaining momentum and creating interest among architects. The construction schedule or the 4d sequence of the project is related to the point cloud scan data. Users click on building objects in 4D visual environments, viewing associated tasks in the Gantt chart.

 

  • Facilities Management Integrating COBie Data Integration – Facility management is one of the best scan to bim best practices, where scan to bim companies support AEC project stakeholders to organize approved submittals from laser scan point cloud data during renovation and extension. A comprehensive contact data has the records of all construction projects. The BIM modeling drawings and models could be easily accessed through server directories. BIM consultants follow COBie process for asset facility management.

How scan to bim companies work with point cloud laser scan to BIM?

Point Cloud Laser Scan to BIM

  1.  Identifying Information Requirement:
  • Building elements, Level of Detail (LOD) and non-geometric attributes
  1. Setting parameters for Scan to BIM Process:
  • Accuracy, resolution of space, coverage and other attributes such as location, resolution, etc.
  1. Capturing Reality with 3D laser scanner:
  • Collecting data with high speed and accuracy, represents an accurate digital picture of 3d mapping of sites through multiple point cloud scans using popular laser scanning tools like Faro, Trimble, Riegl and Leica.

Types of scan to bim process:

Scanning process gets executed in several ways including:

  • 360 Degree Scan, providing a complete 360 degree view of the construction site
  • Time-of-Flight Scan, measuring distance between horizontal and vertical angles, in order that the scanner head occupies all grid positions for scans.
  • Phase-based Scans, calculating the phase shift of returning laser energy for gauging distances.

Point Cloud Revit Scan to BIM workflow

  • Input requirements for Scan to BIM modeling & construction drawings

How Information Flows in BIM Throughout Facility Operations?

facilities operations management services in USA

BIM facility operations –  Building Information Model is the storehouse of information about numerous services and project participants starting from the design build stage to the operation phase. The information in the BIM model keeps on updating as per the changes made by the stakeholders. As a result of which, it is essential to know how the information flows in the building information model and is exchanged in BIM.

Let’s now have a look at how the information flows in BIM throughout the project facility operations:

Flow of Information during the design-build phase: Usually, the design build process is divided into architectural, structural and facility engineering. The facility operations encompass designs of electrical, water supply, drainage, HVAC and thermal power.

  • Architectural Design encompasses graphic design, shape, façade, etc.
  • Structural design delivers the structural scheme of architectural building design to get unified construction structure.
  • Electrical design provides solutions for the constructing electrical equipment and lighting power, along with the design of lightning protection grounding and weak current provision.
  • Water supply and drainage design include the water supply system of building, internal drainage and rainwater drainage system.
  • HVAC embraces heating system design, air conditioning together with ventilation and smoke control system.
  • Thermal power design for residential building consists of gas system design, pipe network layout and hydraulic calculation of the gas pipe network.

Building design gets constantly enriched through coordinating amongst the architectural, structural, electrical, plumbing and mechanical professionals.

Flow of Information during the construction phase

  • The architectural along with structural engineering stage gets divided into four segments, including foundation, structure, waterproof and building decoration engineering. Foundation engineering for architectural and structural services encompass the relative elevation of 0.000 mm underneath the building foundation, waterproofing and protection of foundation pit engineering. Constructability analysis through Building Information Modeling facilitates in drawing an information flow model for structural foundation.

Flow of Information during the operational phase

  • The operational phase of a building facility includes reception, usage, maintenance and demolition. During this phase, the asset management right gets transferred from a construction company to a property management firm. The primary task of the operation phase includes property reception. As per the property management regulations, a firm arranges reception work. All information pertaining to the work is obtained from the BIM model at the construction stage. This encompasses project approval documentation, contracts, agreements, facilities operations, as well as property management information. Asset usage constitutes to be another most important task during the operational phase for managing the property in a normal way. Property demolition is the last stage that complies with the laws of the building regulations.

Integrating facility lifecycle information

  • After analyzing the flow of information in various stages, information exchange takes place amongst various project stakeholders. This embraces volume, varied sources, storage and dynamic process of information. The information system in construction gets designed for a specific phase. Building Information Modeling caters facility operations and maintenance, by integrating information from varied stages to facilitate communication and reuse. Further, it is the primary element of understanding lifecycle management in construction. So, the different portions of the BIM include Design BIM, Construction BIM and Operation BIM, though the information within the BIM model is not isolated.

So, Building Information Modeling integrates the entire workflow, starting from the design build stage, to construction and operation. BIM integrates facility operations, establishing an engineering information set, describing the whole building life-cycle. It is the intelligent BIM modeling that realizes the integration and data by extracting and integrating various sub-models. To take an instance, while conducting the building designs of architecture, structure, electric, water supply, HVAC and thermal power as per design stage information, several geometrical data get produced along with the existing requirement for collaborative data access. It’s the construction phase that can extract information from the design build stage and apply it to BIM software applications. Likewise, the operation phase could also extract part of the information from the design build phase and construction stage, and apply that to operational software. Owing to the information preservation and BIM integration, the problems of information loss and errors get resolved. To seek BIM implementation, talk to the BIM consultants of Tejjy Inc.

difference between BIM and CAD
BIM Service, Blog

CAD Vs BIM Vs VDC

Introduction: 

difference between BIM and CADThe AEC industry is rapidly evolving by introducing and integrating digital technology at every stage of the design and construction process. With time, the quick evolution has led to an increase in the dilemma between clients and service providers. As new technologies are launched on a daily basis, it is increasing difficult to determine which approach is appropriate for certain applications.  

CAD, BIM, and VDC are also among the most commonly misunderstood terms in the AEC business. Many individuals confuse the three names and believe they are interchangeable. However, the scope and uses of all three technology – CAD, BIM, and VDC-are vastly different. Let’s have a look at the differences and see how each one has its own set of applications in this blog. 

 

First Generation Methodology, CAD – Computer Aided Design 

CAD is the oldest of the three methodologies. This is a design and documentation tool that utilizes computer technology to produce the most precise, complete, and information-rich model possible within its constraints. It’s generally utilized for planning and constructing complicated projects with various precise parts and components, like mobile phones, aeroplanes, and buildings. 

Both 2D drawings and 3D models are used in CAD. Since the 1990s, 3D CAD has been standard in manufacturing, and it has greatly benefited the industry by allowing more complicated design work to be completed more rapidly and efficiently. Its rapid adoption was partly motivated by the necessity for businesses to stay competitive, as 3D CAD allowed items to be delivered to market much faster than before, causing any company that did not use it to fall behind. Building design has become more reliant on 3D CAD.

Enhanced Collaboration with Advanced Technology, BIM -Building Information Modeling 

While CAD is a technological tool, BIM represents a collaborative process facilitated by advanced digital technology. BIM has produced a significant positive outcome in the construction industry in recent years by providing a holistic approach to construction that combines design, construction, and documentation throughout the project lifecycle. The main difference between BIM and 3D CAD is that a BIM file contains significantly more information, such as performance parameters, requirements, and other non-physical data, all of which are incorporated in a shared 3D digital model of the project. 

BIM Modeling ServicesBuilding Information Modeling is a technologically enabled collaborative design and production process that allows architects, engineers, contractors, and clients to collaborate in a single model, both concurrently and sequentially. Prior to the project’s “breaking ground,” decisions can be made and challenges defined and solved using a shared computer-generated model and database. Prior to construction, clash detection and coordination between trades can be resolved at coordination meetings, preventing delays and issues in the field. This saves time and money while also lowering the impact on the environment. BIM also makes it possible to realize increasingly sophisticated and ambitious 3D designs successfully and safely. 

 

Integrated Models Management, VDC – Virtual Design & Construction 

Consider VDC as a broad word rather than a specific application or technology. VDC is a method of bringing together all of the tools, options, and services used in virtual design construction. VDC, for example, include any tool or, application that falls under the digital construction platform, such as the use of 3D scanning devices to map out installation requirements and take precise measurements, the use of software for man-hours and job scheduling, the use of drones to take measurements by flying over the site, the use of robotics system to map out areas to mark for plumbing installation comparing with the design drawings, utilizing virtual reality and walking through the site using Microsoft HoloLens and moreover, utilization of 3D printing.  

VDC is a term that refers to everything for the use and management of all of these tools and many more, that have yet to be invented. 

Applications of CAD, BIM and VDC in Construction Industry 

While these three names are closely related, the extent and uses of CAD, BIM, and VDC are vastly different. 

3D CAD is a design tool that is used to create industrial things, vehicles, and complex components. It is mostly employed in the industrial industry and is an important aspect of the engineering process. 

BIM, on the other hand, is commonly utilized for large-scale construction projects such as multi-story buildings, transportation hubs, office complexes, and other real estate projects. It is the industry standard for managing everything from design to facilities management through a unified digital model that encourages interdisciplinary collaboration. Please feel free to look through our portfolio of BIM projects. 

VDC is a step forward of BIM, however it is not as widely used in the industry as the other two approaches. VDC is an approach that combines 3D CAD and BIM principles to improve information sharing, comprehension, collaboration, and communication. The architectural design, engineering, and building processes would be more efficient as a result. 

Conclusion: 

The construction industry continues to benefit from technological advancements that save time and money while also improving accuracy. Hopefully, this walkthrough of the technology development and terminology can clarify the misunderstanding. Feel free to contact us for further discussions.

For instance, the hot water of the boiler is supplied to building either through pipes for heating air or for direct use in a kitchen. Chiller tubes and compressors are also used for circulating chilled water through the building for the sake of cooling. Further heat transfer coils, fans, motors, pumps and several other items are found in the mechanical rooms.

Design considerations of mechanical rooms through Revit BIM services also include apt equipment layout and effective drainage. Specific equipment laid out also provides adequate space for regular maintenance of schedule and repair. Adequate ventilation of the room is also considered through Revit Modeling services, that help to prevent overheating of mechanical equipment like boilers, heaters, water pipes, and other things. Revit software also facilitates in preparing the floors of the room and pitch it towards the drains. Instances of 3d equipment models consist of fire suppression system tanks, pendent sprinkler, fire pump, dry valve. etc.

  • Model Coordination & Clash Resolution

BIM engineers produce coordinated BIM model, resolving clashes amongst the various services of architecture, structure, MEPFP, concrete and accurate mechanical drawing services are delivered to clients. Clashes get resolved in the Revit model through sharing of 3D clash snapshot. MEP engineers also mitigate clashes by re-routing utilities, modifying elevations and re-sizing of elements. BIM Value Engineering facilitates in enhancing system efficiency, mitigating costs and easier construction and maintenance.

  • Shop Drawings

MEP Shop Drawings are obtained by the BIM model as per project standards. The mechanical drawing services help building contractors, fabricators, suppliers and manufacturers at the time of construction. Further Building Information Modeling facilitates in the construction of complex structures and generate accurate sleeves, penetration and hanger locations from the 3D BIM model at the onset of the construction. The mep shop drawings produced directly from coordinated BIM models are comprehensive enough for workshop fabrication as well as for making on-site construction.

  • Mechanical Quantity Takeoff/ Bill of Materials

BIM helps to produce an accurate quantity of all materials of MEP services from the 3D model. Bill of Material (BOM) reports get formatted in MS Excel and exported to database for making detailed analysis. Quantities are generated for a specific period of time or project area in 4D scheduling or 5D BIM for managing material procurement and saving inventory costs. Bill of Materials covers accurate measurement and 5D cost estimation of ducts, fittings, equipment and hanger.
