Using Scan to BIM Services to Reduce Rework and Delays in Construction Projects

Everyone has heard the saying “time is money”. And in an industry where all the rework and delays cost a significant amount of money, you remember it especially well. The Associated General Contractors of America report that 72% of firms report that projects have taken longer than anticipated, with outdated as-built drawings, design inconsistencies, and field-to-office data gaps being key contributors.

Wouldn’t every chance to make the process faster without losing quality be a big help? Especially when the lack of data, communication, and details is a big part of the delay and rework causes. So, how can we eliminate guesswork, save money, and make the work more efficient? This is where Scan to BIM comes to help!

What is Scan to BIM

The construction industry has experienced a massive efficiency shift after implementing scan to BIM technologies. This cutting-edge technology allows teams to capture in-built data with precise accuracy by using laser scanning. It creates a point cloud – a digital copy of reality. Using it, BIM professionals generate a model that shows the real condition of the building, MEP (mechanical, electrical, and plumbing) systems, and it doesn’t fade with time. So, Scan to BIM closes the gap between the physical site and its digital twin.

What Causes Rework and Delays

The key to solving a problem is understanding what causes it. So, first, we have to analyze why rework and delay are such a huge problem in this fast-developing industry. 

Inaccurate site measurements 

Measuring large objects by hand can lead to inaccuracies caused by human factor. 

Communication issues 

Sometimes, there can be gaps in communicating some measurements and systems between different parts of the team.

Unforeseen site conditions 

Lack of detail or outdated plans can lead to many problems. 

On-Site Clash Detection Issues 

Unexpected discovery of structures, objects, or property damage leads to expensive rework.

Scan to BIM benefits

So, what makes this technology exceptional? Let’s take a closer look:

  • Capturing accurate reusable data. While traditional methods are prone to human error, laser scanning captures every detail with astounding precision. Losing even small details sometimes can lead to big problems and expensive rework. The precision of laser scanning allows every member of the project to work on it without worrying about unexpected clashes. Moreover, it is a long-term investment that can be used way more than once! 
  • Precise conflict detection. Creating true-to-site digital environments eliminates the interference of MEP or other structures. Noticing and dealing with problems of this kind makes the process more efficient and helps avoid delays.
  • Efficient collaboration. Accurate data and conditions eliminate guesswork and allow designers, engineers, and architects to work efficiently without expensive redesigns due to inaccurate measurements or the lack of them. 
  • Fast transformation into a 3D model. Instead of scanning the physical site manually for days, it can be done with laser scanning in a few hours. This cutting-edge technology drastically saves time and eliminates the chances of delays occurring. 
  • Improves visualization. Highly precise digital model leaves no gaps in visualizing the final product: you can see every part of it in detail before the construction even starts!

So, while some may think scanning is a side task that can be left out, many benefits uncover the truth of it: this part is a game-changer for every step of the project. You can talk to our professionals to learn more about how it can go for your project.

Understanding the Scan to BIM workflow

  1. Defining objectives. First of all, you need to make sure there are no miscommunications. Before starting the scanning, the team needs to determine the necessary LOD (Level of Detail), element types, etc. For that to be done, identifying the accuracy-sensitive zones is required. With that, the development of the scanning route can be started. This is needed to avoid distortions and keep scans as accurate as possible in critical architectural and structural zones.
  2. Site laser scanning. After acquiring all the required information, the scanning itself can start. Using terrestrial or mobile scanners, a 3D scan is conducted on a physical site. The scanners capture millions of points, creating a point cloud that shows every part and dimension of the object.  
  3. Processing and validating the data. Now the raw scan data needs to be processed, cleaned, and edited. It is often done in software such as Leica Cyclone or Autodesk ReCap. The noise is removed, and all the scans are merged into one dataset. 
  4. Precise BIM modeling. With scanned data imported into Revit, A BIM specialist can start working on the model. The result includes walls, floors, ceilings, MEP systems, and all the structural elements needed. The final step is verification that makes sure the deviation from the real-life model is minimal. 

What challenges can occur? 

Inconsistent LOD. Different parts of a BIM team can interpret the required level of detail differently, which leads to inconsistency and further problems with the scan. It is important for communication to be clear; otherwise, it will lead to wasted time and resources. 

Need for high-quality scans. Complex environments, multi-floor buildings, site accessibility, and scanner resolution can all affect the scan. For more complicated scans, it is important to have trained professionals who know what can cause problems and how to solve them, as well as high-quality equipment and scanners. 

ROI. While such a great amount of time can be saved with laser scanning, it definitely does require a lot of resources and can be costly. A firm needs a group of skilled professionals, high-quality equipment, software, and training for employees. But though it can be expensive for beginner firms, the result justifies the price,

Software compatibility. It is critical to be able to select one file format for the project. All parts of the team have to be able to work with one file format; otherwise, the process can be slowed down.

Conclusion 

With the existence of Scan to BIM technology, the existence of so many buildings can be enhanced. You can let old buildings show the details of their story or let modern constructions be in their full bloom by using this 3D technology. Enhanced quality, longer life of the project, and reduced waiting and stress. 

Let us reveal the unknown to you and learn together about hidden parts of the projects that will thank you with their endurance, confidence, and clarity.
