COBie and its Relation to BIM

A BIM Manager in experienced BIM companies is responsible for managing and supervising the collation and coordination of COBie data. But what is COBie & its Relation to BIM and how it is associated with BIM (Building Information Modeling)?
COBie, a non-proprietary data format for the publication of a subset of building information models (BIM), focuses on delivery of precise asset data as distinct from geometric information.

What is COBie in BIM?


COBie is an international standard governing the exchange of information on managed assets, such as space and equipment. It is commonly abbreviated as Construction Operations Building Information Exchange. COBie is strongly related to approaches to design, development, and management of built assets based on Building Information Modeling. 

 Construction Operations Building Information Exchange is a contemporary data file format. It is meant to simplify the process of delivering information about a building to its operators and stakeholders. COBie BIM is often a data format based on international standards for exchanging critical data about building and structures. Construction documents, equipment lists, warranties, and maintenance plans are all included in this BIM COBie format. 

Journey of COBie

Way back in 2011, the Government of the United Kingdom published BIM Working Party Strategy, proclaiming that all the construction projects should be completed with 3D BIM collaboration by 2016. The software requirements along with the data contained in this report are entitled as COBie. 

Looking further at this strategy paper it reads:

5.5 Improved Information Handover
In order to improve the measurement and management of public assets, it is recommended that public clients request that specific information be delivered by the supply chain. The specified information set, called COBie, delivers consistent and structured asset information useful to the owner-operator for post-occupancy decision-making.

This was because construction delivery has been a bit of struggle as the information generated in the project is partially applicable to the operations team. Further, this entails a lot of new documentation that should be produced and collated for them, in the form of documents and paper drawings in binders. The bulk of the documentation work thus gets delayed until the end of the project which is usually the time when budgets have been spent with an impending deadline. Through the digitized world, the information gets moved from the archive room onto the file server, assisting the project team in easy access of the data. 

Understanding COBie 

The Construction Operations Building Information Exchange (COBie) is a non-proprietary format of data for publishing a subset of construction & BIM related information, with a focus on supplying asset data in non-geometric form. This may appear to be somewhat complicated, yet the concepts are easy to understand. It is a simplified format for transmitting asset data. It is usually a spreadsheet file with some constraints governing the structure and content of the data provided.  

The COBie spreadsheet has multiple tabs that provide information on assets, facilities, floors, spaces, systems, installed equipment, papers, and so on. Every entry in the worksheet is linked to an entry from another worksheet. It is meant to serve as a handy reference for information or data that would otherwise be lost in the enormous number of drawings and files generated on a project. Using the COBie specification, professionals may quickly update the relevant paperwork in real-time throughout the building construction phase before handing it over to the customer or facility operator. This makes the documentation process easier for the end user to grasp. 

How COBie streamlines data collaboration/information exchange for effective data management?

The COBie spreadsheet comprises data and information on the facilities, spaces, floors, systems, installed equipment, and relevant documents associated with a building project. It also contains a wealth of information regarding the project’s activities on a variety of different levels. All of the data entries inside a COBie sheet are hyperlinked to other data entries with the goal of adding value and making information more easily accessible.  

Since entries in a COBie spreadsheet or data are interrelated, the information exchange process is simpler and more productive for all parties involved in the process. End-users, such as facility managers, no longer have to sift through mountains of manual sheets or sift through a jumble of unstructured data in order to obtain information at various stages throughout the facility’s maintenance lifecycle. 

Fundamental Values of COBie:

COBie is considered to be a great stepping stone in the process of transferring construction information from paper to online. This is because the prime objective of COBie lies in substituting the home-based exchange templates & point at the solutions with an additional building information management.

COBie includes:

A COBie BIM model includes the following for effectively transferring the information:   

📝 Categorization – COBie uses a categorization system, albeit no specifics are given. The project owner decides on the categorization scheme. Using a categorization system aids users in finding information that aids project owners.   

📝 Data Model – COBie is aligned with the Smart Building data model, indicating industry best practices. The COBie IFC data model facilitates the integration of construction and design technologies.   

📝 Setup COBie offers customers a variety of distribution methods, including spreadsheet data transmission. The beauty of this format is that it allows you to participate in an open BIM project without knowing anything about the IFC data model or a specific BIM program. 


Structure of COBie Data Model:

Structure of COBie Data Model

COBie shares the structure of the building smart data model, featuring 3 main areas including DesignBuild Common. The design area constitutes the core of the information and comprises of the following information like:

  • Components – A vital part of an asset register
  • Kinds of Product Category
  • Spaces/Rooms
  • Zones/ Grouping of Space
  • Building Facilities
  • Equipment of Floors & Systems

The building information encompasses an occupation, resource & replacement and is an endeavor to assemble the non-standardized data found in the documents like maintenance strategies, operating guides and spare part lists. The shared things cover data to be linked to all items in the other categories, such as the contacts of the people involved in the project, documents about the delivered equipment, features including the method of tagging customized data to any item type and classification.

Advantages of implementing COBie in construction projects

  1. Improved Data Management

As part of the building project cycle, an enormous amount of data is generated and transferred between parties. The information contains BOQs, RFIs, different safety licenses, paperwork from the planning department, and so forth. The list goes on indefinitely after that. COBie is a data management system that allows you to organize and manage your data in a common format.  

As a result, the most important advantage of COBie data collaboration is that it facilitates data administration in a uniform way.  

2. Enhanced Data Sharing

COBie facilitates the efficient exchange of information across facility management tools such as BIM authoring tools, construction management systems, and CAFM (Computer-Aided Facility Management) packages. Using the standard, facility management organizations can reduce the need to re-collect data and, as a result, reduce the number of errors across relevant data sets utilized for various purposes inside the business.  

3. Compilation of Information

Before upgrading to a new building maintenance software, managers may collect data using COBie standards to help them plan their projects. It is not essential to get a proprietary vendor spreadsheet in order to facilitate data collecting. Furthermore, it is not essential to pay the CMMS provider to map the spreadsheet software that was built in-house. Instead, the data gathering in COBie is done in a format that is widely accepted in the industry.  

4. Transfer of Information  

In the present condition of the construction business, COBie has shown to be the most effective technique of transferring construction data from one site to another. It exports construction information from BIM authoring tools and imports it into a CMMS resolution that is COBie-enabled, as described above. 

COBie as a Requirement:

The COBie standards are created as a reference for construction, design and product delivery. However, a simple reference to the COBie standard is not enough. Few specifications need to be given. Further the objects essential for maintenance should be included.

Some of the COBie specifications include:

  • Classification system to be used
  • Custom properties for every building item
  • Process of tracking relations to BIM models
  • Type of delivery process – continuous, data drop for each phase, change or as a part of the handover
  • Collection and coordination process
  • Stakeholders to be involved in the coordination process – be it owner, main contractor, BIM manager, Architect, etc.

The Compound Annual Growth Rate is expected to rise at 7.5% from the year 2021 to 2026. The continuous growth of the scanning technology would give a boost the construction sector, facilitating the owners, buyers, stakeholders and all other construction professionals. 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.

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.
