Types of BIM Construction Drawings in Building Design

April 5, 20210

The creation of construction drawings before the construction process is compulsory. They like an assistant to the architects, engineers to convey their ideas and concepts about the building. In this article, we want to give you an overview of different types of BIM construction drawings in the building design. It will help you understand and do your work better.

Types of BIM Construction Drawings

There are many different types of BIM construction drawings created during the construction and designing process. We have covered some of the commonly-used drawings like architectural, structural, MEP construction drawings. These drawings will allow you to know better about layout plans and detailed information for each part of a building.

Let’s take a look at these drawings to understand about its purposes and functions.

1. Architectural Construction Drawings

Architectural construction drawings provide you with a detailed overview of the building design. They include different types of ones like Site Plan, Floor Plan, Line Plan, Cross Section Drawing, Landscape Drawing, General Note, etc. These drawings are developed at the final step of the architectural design process. They contain more detailed information than the concept design drawings.

  • Site Plan: The drawing gives you an overview of the construction site. It helps builders know the scope of construction activities. Besides, it also lets you identify the typography of the building.
  • Floor Plan: The floor plan describes the dimensions and different kinds of installments.
  • Line Plan: The line plan gives you an overview of the layout for the whole room. It helps to identify the sizes of the rooms, the position of the doors.
  • Cross Section Drawing: A cross-section drawing shows the components of a building vertically. It provides an overview of both the visible and hidden areas of the building.
  • Landscape Drawing: The landscape drawing shows the aerial view of the whole building area. It also demonstrates the external aesthetics of the building.
  • General Note: A general note consists of details like codes, length, construction type, abbreviations, etc

2. Structural Construction Drawings

Structural construction drawings are a bunch of drawings that present the structural aspect of the building. These drawings give you more details on locations, size, spacing details, and materials specifications of structural components.

Some structural drawings are Column Layout, Roof Slab Layout, Framing Plan, Assembly Drawing, Roof Beam Layout, Foundation Plan, etc.

  • Column Layout: The drawing focuses on the design and pattern of the columns of the entire structure.
  • Roof Slab Layout: The roof slab layout shows detailed information of the floors, roof faces, and other surfaces.
  • Framing Plan: It provides information about the framework, sizes, and positions of the beams.
  • Assembly Drawing: The purpose of the drawing is to describe the connection between two elements. It can include 3D, sectional, and elevational views.
  • Roof Beam Layout: The roof beam layout allows builders to know more details about the material specifications.
  • Foundation Plan: The drawing presents information about the dimensions, sizes, shapes of a floor. Footings are also a crucial part of a foundation plan.

3. MEP Construction Drawings

MEP construction drawings will include the location, identification, and installation details of all mechanical, electrical, and plumbing systems in the building.

The mechanical construction drawings will let you know the location and size of mechanical equipment, ductwork. It includes connection details as well.

The electrical construction drawings present the location of all power, lighting, switches, fans, etc. These drawings allow electricians to understand the wiring diagrams on the floor. Besides, they also specify the load capacity and information regarding the air conditioning or the heating systems.

Like the electrical drawings, the plumbing drawings will show the layout of the plumbing elements. They include the water drainage system and the piping system of a building. Besides, they provide you with the location and size of pipes. Or it may show the position of the taps and other water outlets on every floor.

Besides, the mechanical drawings also include HVAC drawings and firefighting drawings. The HVAC drawings give you information about the heating and ventilation systems. Firefighting drawings point out the placement of the fire hoses, points, water outlets, etc.

The MEP system is complex, so it often requires BIM coordination before making the MEP construction drawings. This activity helps to detect clashes or conflicts in the design before starting the construction process.

5 Benefits of Outsourcing BIM Construction Documentation

April 1, 20210

Construction Documentation is one of the most crucial pieces in the construction project. So your in-house team often spends a lot of time and effort developing it. But there is always for you to optimize its efficiency and cost. That’s to use the 3rd-party vendor available with human resources, technology, and expertise in the industry.

Today we’ll look at the five benefits of outsourcing Architectural, Structural, and MEP BIM Construction Documentation.

But first of all, let’s get started with the definition of Construction Documentation (CD)

1. Construction Documentation aka Construction-ready Drawing

Construction Documentation (CD) is created after you’ve already completed the Design Development (DD). It’s a construction-ready drawing that reflects design-intent changes and clash solutions. The information of construction documentation is of value to stakeholders like contractors, engineers, suppliers, etc. Construction Documentation assures the completion of the building projects with the maximum accuracy and the minimum of mistakes.

Regarding the technical aspect, Construction Documentation provides you with essential detailings like material specifications, installation details. The information is used to serve the purpose of bidding, construction process administration. Construction Documentation includes a set of drawings for various engineering trades like Architecture, Structure, MEP.

2. Five benefits of outsourcing Construction Documentation (CD)

Many organizations have started to count on 3rd-party vendors to develop Construction Documentation instead of their in-house teams. They realize the benefits of specialization, so they are more willing to outsource their construction documentation to reliable providers. We’ve covered five benefits of outsourcing your work to help you make informed decisions in the future.

Lower costs and increase efficiency

The cost is always one of the crucial factors in the business operation puzzle. Running an in-house team requires you to prepare a lot of different resources. You need to buy equipment, software, recruit skilled personnel, and plan for the training. However, when you outsource the work to 3rd-party vendors, you can reduce all of these costs.

BIM construction documentation - lower cost

Besides, the vendors have extensive knowledge and experience in executing projects for various customers in multiple countries. Thus, you can utilize the skills and expertise to improve the quality of the construction documentation.

Moreover, you should have a minimum number of core staff who work directly with your vendors to ensure the quality you want. In this way, you can save a hefty sum for salaries or operational costs.

Give you time to sharpen core areas

When you outsource to the 3rd-party vendors, you free your in-house team to enhance their core areas. It allows them to focus on seamless project management, improving the working process, or strategic activities.

Moreover, outsourcing BIM construction documentation will let you take on more projects but still optimize costs. Your in-house team will avoid being overwhelmed when having lots of projects with a tight deadline. They will focus on managing the project smoothly instead of doing a large number of documents.

Fasten turn-around time

The faster turn-around time of the project can make your customers happier. When working with BIM outsourcing companies, you benefit from different time zones. The work will continue even if you are out of work or your office is closed for some reason. Let’s take the COVID epidemic as an example. Although many companies in the US, UK, Australia, and more have been closing their office, their vendors still get their work done.

BIM construction documentation - turn-around time

If you look for the right BIM outsourcing company, then you always get on-time delivery. You only need to set a proper schedule for the provider, and then you can assure prompt delivery of the construction documentation.

Meet the global standards of quality

Quality is a deciding factor whether your customer stays with you or not. Thus, staying well versed with the industry standards is a key to delivering high-quality construction documentation. By letting the 3rd-party vendors get the work done, you can use their skills and expertise.

BIM construction documentation - quality

Companies own skilled modelers, engineers who are directly executing the global projects. So they understand the BIM technology, industry standards and can deal with any project challenges. Even better, they can adapt to suit your design standards-compliance and technical requirements.

Ensure data security

Data security is a big problem when it comes to construction projects. Most outsourcing companies have a well-developed technology infrastructure to protect your project data from destruction. Some trusted companies like ViBIM always put data security over all else. Only authorized employees can access the project data.

BIM construction documentation - data security

Moreover, you can ask them to sign a Non-Disclosure Agreement that helps to handle confidentiality effectively. Nobody can disclose the project data as it would result in heavy fines, affecting their reputation. So most companies ensure data security to build long-term and trusted relationships with their customers.

Last words

The market of the construction industry is more and more competitive. You wouldn’t want to get left behind due to high prices and poor quality. It’s time to understand why you should consider outsourcing their construction documentation to enhance the competitive edge.

File transfers – How to handle large point cloud data file

March 4, 20210

If you’re working with an outsourcing BIM partner, file transfers are a big part of your daily work activities. You might ask yourself which methods help you send large amounts of data files to your supplier. Is it a secure way to share your project data or something like that?

When to come to this problem, some of our customers usually ask us a question:

“How do you handle point cloud datasets? Is there a file-sharing service that you use?”.

Choosing the best ways for file transfers is not easy. Several popular options include email files, cloud-based sharing, or a more complex way like FTP (File Transfer Protocol).

Each method has some of its advantages and disadvantages. The article will give you an overview of the popular methods coming with benefits and drawbacks corresponding. Besides, we also want to keep you updated on how we handle file transfers for our customers.

Let’s continue exploring it below!

1. Several ways to transfer data files

Method 1: Use cloud-based storage and sharing

Cloud-based storage and data sharing have become significantly popular in recent years. In a crowded cloud-storage market, we have to highlight some names such as Box, Dropbox, Google Drive. It has become a mainstay for sharing data files, models, and documents. In reality, some of our customers often use their cloud storage services such as Wetransfer, Box, Google Drive…to share data files with us and their suppliers.

point cloud file transfer - cloud-based sharing

However, any method has some benefits and drawbacks. Cloud storage is no exception. Let’s take a look at a list of the pros and cons of this not-so-new way.

Pros

  • Accessibility: As your data is stored remotely, you can access it from anywhere with an Internet connection. It is helpful when you work with outsourced BIM partners in different countries worldwide. Just share with them the link of data files in the cloud storage, then your project team can access them easily;
  • Cost-effectiveness: With cloud storage, you only pay a little or no cost for a small or medium-sized business. You don’t also need to invest in expensive server infrastructure. This way can help you save your annual operating expenses;
  • Fast speed: The file transfer using a cloud-based platform is quick. The speed achieved can rival onsite scores;

Cons

  • Security concerns: Easy accessibility also triggers some security threats. When you use the clouds, it means you’re storing your data in a third party. Anyone can access your data with an internet connection. So, it might lead to a negative impact on your project data confidentiality;
  • Internet-dependent: In case you lost the internet connection, you will access the file data. Besides, if your internet connection is slow, it takes a lot of your time to wait than usual to access your data;

point cloud file transfers - cloud-based

There are other advantages and disadvantages of the cloud options. However, we only list some typical factors you should consider.

Method 2: Use The FTP server sharing

File Transfer Protocol (FTP) is a set of rules which let networked computers exchange information. The use of FTP server sharing is simple. You have an account, then log in to an FTP server, find the correct folder, and exchange files. When working with customers on BIM projects, several customers share their data files with us directly from their FTP server.

FTP server sharing, like any other method, has some of its pros and cons. So it’s crucial to understand FTP fully. Let’s continue exploring the benefits and drawbacks of FTP and learn how these factors impact your work.

point cloud file transfers - ftp server
Pros

  • Large file transfers: Point cloud data generated by laser scanners are getting bigger. Large projects can include hundreds of gigabytes of data all at once. FTP eases those large transfers with a rapid speed compared with cloud-based methods.
  • Resumed file transfers: If your file transfer is interrupted, don’t worry too much about losing progress. By using FTP server sharing, you can recover an interrupted file transfer if your connection fails.
  • Safety: With FTP, all files stored in your FTP storage account are safe. There is no risk of fire/water damages or theft.

Cons

  • Control: With several FTP solutions, you can not track what has been uploaded on the remote system, so you need to require reporting with an FTP vendor.
  • FTP vendors: There are differences between vendors. Each vendor offers its own set of features and lacks many of the features you need like controls, usability, etc.

2. The latest update from ViBIM on file transfers

We have already invested in our FTP server to transfer a large volume of laser scanned data/point cloud files to a customer. It is a convenient, fast, secure, confidential, flexible delivery gate that directly connects our server to the customers’ PC / server. We will share the host with the client for uploading the scanned files when implemented.

point cloud file transfers - ftp-server

At ViBIM, we are very seriously interested in protecting client data and NDA. Our server is very protected. Only authorized project managers can deliver data/models to clients under a secured server. No one in our company can copy data to USB or upload/attach it on the internet thanks to firewall restrictions.

Besides, we can still use some cloud storage such as Box, Google Drive, Wetransfer… We can host cloud sharing if it is much convenient in our collaboration approach.

Conclusion

In general, any method has some advantages and disadvantages. You should choose the one that best suits you. If large projects involve many stakeholders and the exchange of quite a few files, you can consider file transfers via an FTP server. Make sure that you have access to enough storage space to keep your large datasets.

Researching BIM outsourcing service providers: 7 questions you should ask

December 29, 20200

Outsourcing BIM services has been an effective solution for many companies. However, the expertise and competency of the BIM provider could be a decisive factor for your project’s success. Choosing the right BIM company assists you to avoid project hassles at a later stage. So make sure that your expectations align with what the BIM partner offers.

To help you, we’ve sorted out a list of 7 questions to ask BIM outsourcing service providers about their BIM capability. Absolutely, these questions will assist you to decide if a BIM outsourcing provider fits your needs.

1. Question 1: How do you protect client data and NDA?

You should put your data security first and verify that your project data is safe with your BIM provider. Also, you can ask them to explain how they protect your project data. Commitment is an important factor so a Non-disclosure Agreement (NDA) should be signed. This ensures that all data and information you provided will be confidential. No one will disclose any information about the project to any third party without your prior consent.

What’s more, it’s essential to check its IT infrastructure system to guarantee your project data from destruction. Let’s take a look at some specifications relating to the server system, computer performance, or data client delivery.

2. Question 2: What type of projects do you execute?

A great way to evaluate BIM providers’ capabilities is to take a look at the real-life projects they implemented for their clients. You might get to know the different types of projects they are doing well. Some often focus on infrastructural projects whereas others specialize in building industries such as Residential, Commercial, Industrial, Healthcare, Educational, etc.

BIM outsourcing service providers

In this way, you can check if they are able to meet the industry requirements and current trends. As normal, most BIM companies often show off several executed projects on the website. Taking a look at their successful projects is also a great way so that you can explore their BIM services.

3. Question 3: Can you provide me a price range for your services?

Normally, BIM providers will not publish their pricing plans on their website. Thus, you will need to find out more about the price when reaching out to them. A note that low costs are not always the best deal. A trustworthy company will always quote an affordable price with the efforts.

In reality, some of our clients share that they are offered low prices by some BIM companies. Then when having already deployed several real-life projects, they are charged at a higher cost with the poor quality of the deliverables. This can tell you that low cost does not always guarantee the quality of the final models. Companies offering lower costs may lack the expertise or professional skill to create BIM models.

The price of a BIM project often varies depending on the scope of work, level of detail (LOD), tolerance, parameter, building technical components, etc. So if you want to define the exact cost, the best way is to send them a data file with a very clear BIM scope of work. You can do the same way to all BIM providers you’re considering. A comparison in cost and quality will assist you to make informed decisions.

Want to know about our quotations?

Please send us your project data, our BIM consultant will work with you and give you a budgetary quotation.



Question 4: How is your Quality Assurance / Quality Control (QA/QC) process?

Quality is a vital part of any outsourced BIM projects. It is derived from all the steps of creating the BIM model to the deliverables of the project. This can affect the result of the final deliverables. So checking quality assurance and quality control should be considered in mind. You should ask BIM providers about how they have been conducting their Quality Assurance / Quality Control (QA/QC) process. If the process is good, you can rest assured that you could get a high-quality BIM model. To help you get an understanding of the QA/QC process, we crafted the article Quality Assurance / Quality Control for Scan to BIM projects. Hope this will help you to know better.

Question 5: How will you communicate with the client?

Communication is another vital factor in any outsourced BIM projects. Let’s say, you’re working with a BIM provider. You send them the project requirements but there is always a delay to respond to your requests. What’s going to happen? It’s more likely that the project progress will not be on track. Thus, it’s necessary to clarify how the BIM provider communicates with you and how long they respond to your request.

Keeping a connection during the project is essential to ensure that you stay updated with your project. A BIM provider with prompt communication can be a good choice for you.

BIM outsourcing service providers

Question 6: What software do you specialize in?

There is much software that supports BIM modeling, so you can check what software the BIM provider often uses to create BIM models. Some are working with Autodesk platforms such as Revit, Naviswork, 360 BIM, Recap, or AutoCAD.

Besides, there is also some other BIM software including ArchiCAD, Vectorworks Architect, AllPlan, BIM Track, and more.

Question 7: Do you provide a pilot project so that we can check your capabilities?

A real-life experience is worth a thousand words. This also holds true when you are evaluating the capability of a BIM company. Most BIM providers commit to high-quality BIM services. But whether you should take their word for it. The best way is that you should have a first-hand experience of their capability. This allows you to assess their professionals’ skills, knowledge, strengths, a record of accomplishment, and technical expertise.

Let’s ask them for a small pilot project in order to check how they communicate with, commitment, and most importantly, the quality of BIM models.

Wrapping up

Before you make a final decision, make sure what the BIM provider offers is suitable for your expectations. We hope the 7 questions above will assist you to find the best-fit BIM provider for your needs.

If you want to ask these questions, feel free to let us know. We will send you the official introductions that help you get an understanding of ViBIM services.

Quality Assurance / Quality Control process for Scan to BIM projects

December 16, 20200

The quality of a Scan to BIM model is one of the most important factors when you choose a BIM services provider. There are no standards to stick to, nor any tools that automate this task. However, at ViBIM, we always prioritize quality over everything. Thus, we build effective Quality Assurance / Quality Control (QA/QC) process for every Scan to BIM project.

The article aims to offer you a general understanding of the QA/QC process. Besides, we want to share how we conduct the QA/QC process for Scan to BIM projects. Hope that it aids you to control the quality of a BIM model created from point cloud data better. Let’s keep reading to find out more information.

1. Why is Quality Assurance / Quality Control (QA/QC) needed?

The process of creating a 3D BIM model involves several steps. At each one, there is more likely to appear inadvertent errors. These errors can impact the accuracy of the final model. It’s why we need to conduct the Quality assurance / Quality control (QA/QC) process. It ensures that you get a high-quality BIM model. By undertaking the QA/QC process, you can

  • Eliminate errors, clash issues in the process of modeling;
  • Assure to follow the standards while creating BIM models;
  • Ensure enough geometric elements, the correct position, functionality;
  • Make sure that a BIM model meets the client’s accurate requirements;

2. What is the QA/QC process for Scan to BIM projects?

Quality Assurance (QA) and Quality Control (QC) are two concepts that are often used parallelly. Although they are the same, there are distinct differences between the two concepts.

Quality Assurance (QA) shows you how a BIM model is created from laser-scanned point cloud data. In other words, the QA identifies standards or methods that need to be followed to meet the client’s requirements. The QA is often used to monitor and verify how you are doing is right.

If the QA is a process to create the deliverables, Quality Control (QC) is the process to verify those deliverables. The purpose of the QC process is to identify and fix errors, clash issues between building trades. The QC process makes sure the results of what you’ve done are what your client expected.

In general, the two terms are related to each other but they are different in the purpose. The QA process focuses on preventing errors whereas the QC process aims to determine and address the errors.

3. How does Quality Assurance / Quality Control (QA/QC) work?

The QA/QC is one of the indispensable parts of our Point Cloud to BIM projects. The QA/QC process is always conducted during the modeling process and before delivering the final BIM models to the clients. We define specific QA/QC processes for both Architectural and MEP disciplines. Let’s get into the juicy details.

QA/QC process for Architectural building system

The QA/QC process for the Architectural building system currently involves key three checks. It includes the quality checking by Naviswork, Revit, and the final step after detaching the file. Checking by Naviswork ensures that the BIM models are enough building elements, in the correct location, and don’t have any clash issues. Besides, checking by Revit makes sure that the BIM models are the correct structure and functionality.

Quality assurance/ quality control for architecture

The QA/QC process will begin once after having already finished the process of modeling. The QA/QC specialist can undertake two processes (Revit, Naviswork) parallel to each other before moving to the final checking step. After having already completed the QA/QC process, we export the file and create a QA/QC checklist to send the client for confirmation.

Curious about the Quality Assurance / Quality Control for Scan to BIM projects?

Our QA/QC specialist is here to help you understand better the QA/QC process for the Architectural and MEP system.



QA/QC process for MEP building system

Like the Architectural discipline, the MEP system has also its own QA/QC process. This involves two main reviews including geometry checking and structural checking. The process assures that the BIM models are enough geometry elements, the correct structure, connection, and don’t have any clashes. The software for the QA/QC process includes Revit and Naviswork. Also, the QA/QC specialist will conduct the final checking step to get a quality BIM model before delivering it to the client. Let’s take a look at our QA/QC process as described below.

LOD Querying Checklist – A great assistant for BIM projects

December 9, 20200

Level of Detail (LOD) is not a new term for anyone who has been involving in BIM projects. But it is obvious that there is still a different grasp between the parties in each project. In the previous blog post, LOD and LOI, and everything you need to know about, we help you clarify different types of Level of Detail (LOD) and its benefits

This article provides you with another aspect of this topic. It gives you an overview of distinct differences between the two terms Level of Detail and Level of Development. Besides, you can also know better about different LOD throughout our BIM projects. Finally, there will be an introduction to the Level of Detail (LOD) querying checklist. It is an assistant to determine clients’ requirements before commencement.

1. Level of Detail vs. Level of Development

LOD is sometimes referred to as Level of Detail and Level of Development. In this article, we use LOD to refer to the “Level of Detail”. There are important differences between the two terms. Let’s dig into two terms below:

Level of Detail

The term “Level of Detail” (LOD) demonstrates the degree to which the element model is detailed and specific. It measures the amount of information provided, increases from a symbolic model to an actual model. For example, modeling the steel framing columns:

  • LOD 100: You can model a basic shape like a “box”;
  • LOD 200: Known as a generic model with approximate size, shape, position. You can also add non-graphic information to the model element;
  • LOD 300: As a specific object with accurate size, shape, position, the orientation of main vertical structural elements. You can also add non-graphic information to the model elements like steel materials;
  • LOD 350: As an actual model including base plates, gusset plates, shape, position, and interfaces with other building systems;
  • LOD 400: Including detailing, fabrication, assembly, and installation information. You can also add non-graphic information to the model element;

Level of Development

The term “Level of Development” illustrates the development of the BIM model from the conceptual design stage to the completion of construction. The LOD allows professionals to develop reliable models at different stages of the project lifecycle. Various LOD specifications have been proposed and adopted in the industry. A typical LOD specification includes five levels:

  • LOD 100: Conceptual design. The model can be used to perform whole building types of analysis (volume, building orientation, cost per square foot, etc.);
  • LOD 200: Schematic design or design development. The model helps users analyze the systems by application of generalized performance criteria;
  • LOD 300: Construction documents and shop drawings. The model is suitable for analysis and simulation for detailed elements and systems;
  • LOD 400: Fabrication and assembly. As normal, trade contractor or fabricator uses the model;
  • LOD 500: As-built model. The model is suitable for the maintenance and operations of the facility;

In short, the two terms are used in the development of BIM models. They show the same model development process but from different perspectives. Level of Detail refers to the geometry of the element while Level of Development refers to both the geometry and the other information. For instance, the application of the model, type of information derived from each level. Architects, engineers, and others can use LOD to clearly communicate with each other without debates.

2. Understanding LOD throughout the BIM projects

Scan to BIM project for Office Building with LOD 300

The project consisted of the Revit modeling for a 9-story office building with LOD 300. We modeled all architectural, structural, and MEP elements i.e. facade, ceiling, framing, duct, pipe, conduit above ½ inches.

3. LOD Querying Checklist – An assistant to clarify clients’ requirements

Knowing the right clients’ requirements is important. Let’s imagine that your client has asked you to develop a BIM model with “Level of Detail (LOD) 350”. You and your client all know about the concept of LOD 350. But it is still can not ensure that both you and your client are getting the same understanding.

Thus, it’s necessary to clarify the LOD requirements with clients before modeling. Besides, a BIM project can have various LOD needs depending on each area or position. By using the LOD querying checklist, the modeler will define the required LOD of each building element. The client can confirm or feedback on what the modeler provides. In this way, you can avoid confusion or debates between the client and the modeler. The following is an example of a LOD Querying Checklist we’ve used in Scan to BIM projects.

 

level of detail (LOD) querying checklist

When every requirement is clearly defined, the process of modeling gets started. In the process of modeling, the modeler uses the 3D view, the section to review LOD, and use Schedule to analyze LOI requirements.

Final thoughts

Obviously, understanding the required LOD is important in each BIM projects. Using LOD, designers and engineers can work with other stakeholders about the usability and limitations of a model. As an industry standard, the LOD is mostly utilized as an efficient and collaborative communication tool.

Differences between Scan to BIM for the design and construction phase

December 2, 20200

Scan to BIM improves the process of new construction projects or renovations in several ways. It adds value in every aspect throughout the building’s lifecycle. It helps users save time and cost thanks to well-informed decision-making.

The BIM models created from the Scan to BIM process have been applied for various purposes according to different project phases (i.e, design, construction, operation, and management). Knowing the intended applications of BIM models will enable you to identify the right information requirements in the models.

That’s why we’ve put together this article for you on the differences between how the Scan to BIM is applied for the design phase and the construction phase. With extensive experience in creating 3D BIM models, we will have suggestions for you on 3D BIM models that are suitable for the intended applications.

But before jumping into BIM models, let’s get started with how the Scan to BIM can be beneficial at each project phase below.

1. How Scan to BIM benefits the design phase

Let’s say you are hired for a project at School. Your clients need to gather documentation on the existing construction conditions. This information is later used to design the building that meets the site conditions. What’s happened if BIM models were created on outdated or fragmented information. It is more likely to waste you much time, even then, trigger significant consequences for all users. So as for this type of situation, the Scan to BIM is a good choice.

The information from the Scan to BIM process is highly accurate and detailed. It enables designers to be aware of the existing site conditions better to make an optimal building design. For instance, a renovation project in the UK applied the Scan to BIM to create reliable and accurate data. All models required LOD 4 in the UK standard.

Not only the design phase but the Scan to BIM also continue adding values to the rest phase of the project lifecycle. It plays a more and more vital role in every aspect of the construction project. What’s more, it improves communication with the rest of the project team to ensure well-informed decision making. Keep reading the following section to discover the Scan to BIM uses in the construction phase.

2. How Scan to BIM benefits the construction phase

In the construction phase, the Scan to BIM has been adopted for various purposes. Especially, it can help to solve time-consuming and arduous tasks. For instance, you need to collect data to review the actual project progress. To get the job done, you are more likely to have to visit on-site construction to take measurements. This requires careful planning on when you visit the site, the amount of time you’re allowed to spend there, the number of personnel needed for the task.

All this costs your time, resources, and budget. But, by using the Scan to BIM, you can spend fewer efforts on these tasks. Some use-case scenarios of the Scan to BIM in the construction phase include:

  • Quality assessment/ quality control (QA/QC);
  • Early problem detection;
  • Progress tracking on a project;
  • Virtual environments for installation and assembly;

We’ve already analyzed in detail these applications in the previous article How Scan to BIM is used in the construction phase. Now hope that you can know the different applications of the Scan to BIM in each project phase. The next step is that you need to identify the information requirements of the BIM models.

3. Differences of required information in BIM models

The different uses of the Scan to BIM require different information in the BIM models. Thus, it is essential to identify all the requirements for the intended BIM models before getting started with the process of Scan to BIM. This enables you to avoid collecting too much information or insufficient information that impacts the quality of the BIM models.

So what requirements do you need to determine? There are three aspects we need to identify including:

  • Required building elements: Refers to the building elements that should be modeled in BIM models. For instance, stair, exterior windows, exterior walls
  • Required level of detail (LOD): Lets you know the degree to which the building element is detailed. Five popular levels include LOD 100, LOD 200, LOD 300, LOD 400, LOD 500;
  • Required non-geometric attributes: Refers to some properties such as materials, colors of the building elements;

As mentioned above, the Scan to BIM application is different between the design and construction phases. So what information are BIM models included for these phases?

3D BIM models for the design phase

According to the NBS report, 71% of designers expect that manufacturers should create fully-functional parameterized 3D BIM objects. In other words, 3D BIM models for the design phase include two key factors:

  • The functionality of 3D BIM objects. For instance, assigning internal or external function to BIM objects, adding tolerance of all warped objects, etc;
  • Valuable and rich information. Some information includes size parameter, materials, naming conventions, etc;

The BIM models can need high LOD specification such as LOD 300, LOD 400. Creating parametric 3D models makes reviewing become quick, accurate, and intuitive. Also, it gives designers the flexibility to respond to on-going design challenges.

3D BIM models for the construction phase

Yet, there will be a little bit of difference in BIM models for the construction phase. Unlike architects, some contractors use 3D BIM models to track the project progress or clash detection. Thus, the BIM Models generated from the Scan to BIM process may be less detailed. The BIM models for this type of application can be within LOD 200-300. They expect BIM models include some factors that help them group clashes or search components

How Scan to BIM is used in the construction phase

November 27, 20200

As many construction projects have adopted BIM technology, we witness a natural surge of Scan to BIM. The Scan to BIM refers to the use of 3D laser scanning to capture existing conditions of buildings as point cloud data and the creation of BIM models from these data. In construction projects, the Scan to BIM brings benefits to each and every project phase such as design, construction, operation, and management phase. However, each phase has different requirements depending on the purpose of use.

In this article, we will shed some light on how Scan to BIM is applied in the construction phase. This might point out some great ideas that help you improve your Scan to BIM projects. Let’s keep reading on it to get more information.

1. The purpose of Scan to BIM in the construction phase

To get the most out of Scan to BIM models, you need to identify the purpose of using the models first. When understanding clearly how Scan to BIM models will be applied, you will determine the right approach. Let’s take a look at some following use-case scenarios of Scan to BIM in the construction phase.

Quality assessment/ quality control (QA/QC)

One of the popular applications of Scan to BIM in the construction phase is for quality assessment/quality control (QA/QC). The 3D models created from Scan to BIM process are often compared to the previously designed 3D BIM models to identify any discrepancy between them. Also, these 3D models are used to determine the tolerance values specified in the requirements when modeling.

Early problem detection

Let’s imagine you’re hired for a project at a Hospital. The Scan to BIM process allows you to create a 3D BIM model to present to the project team. The model pointed out to all of your project team more than 10 conflicts where the pipework running through a steel beam. With a clear picture of the problem, stakeholders will know what they should do to make a constructible model. For example, the design team will need to make the change and quickly approve a change order. More importantly, the project team avoids costing more money than planned to solve these issues if they weren’t detected before the build.

Monitor progress on a project

Progress tracking is a vital part of the construction phase to assure the project’s progress. The Scan to BIM will be a good choice for this. By scanning the on-site construction works and create 3D BIM models, you might compare them with the designed BIM models to review the project schedule. As a result, you are able to see the actual progress in comparison with the plan and know exactly what the construction works need to be completed.

Create virtual environments for installation

Several contractors utilize the Scan to BIM to simulate the installation and assemblies in virtual conditions. In this way, contractors can recognize any potential problem such as clashes between the components to solve them before creating the actual installation. In this way, the Scan to BIM helps contractors save construction time and costs thanks to early problem identification for installation and assembly.

Generally speaking, use-case scenarios for Scan to BIM in the construction phase is diverse. It can be used for both new constructions and renovations and the purpose is flexible depending on the requirements of each project. With understanding the purpose of Scan to BIM, now you can identify the right laser scanning solutions and create suitable deliverables.

2. Think about purpose-built BIM models

Now it’s time to determine the necessary point cloud data and BIM modeling process. This enables you to create BIM models with the right and sufficient data. In general, we see that the deliverables are varied depending on the requirements of each project. However, to create BIM models that meet the right client requirements, you should create a querying checklist to clarify any concerns like LOD or LOI requirements between you and your clients.

 

BIM outsourcing services

 

For instance, some contractors will need a BIM model for clash detection so the final BIM model may be less detailed than the BIM models created for the design phase. They can expect the BIM models contain factors like name conventions that help them group clashes or search components with ease. If you are not aware of your client’s expectations, don’t worry, the best way is frankly to talk to them to know more. By understanding the client requirements, you can optimize the implementation time of the project but still creating the deliverables meeting their expectations.

3. Self-do it all or outsourcing?

The Scan to BIM includes the process of capturing existing conditions as point cloud data and the creation of BIM models from these scanned data. So there are several ways to optimize the Scan to BIM process for the construction project.

If you are a 3D laser scanning company and hired for a project at school, of course, you can self-perform laser scanning processes and even create BIM models from point cloud data. However, you are completely able to optimize cost for the Scan to BIM project by choosing to outsource a part of the work and focus only on your strengths.

Partnering with a service provider, for example, specializing in BIM modeling from point cloud data may be a good choice. It provides more flexibility to solve varied works, approaching professionals with expertise in each area.
