In the dynamic realm of construction and architecture, innovation continues to shape the way we design, plan execute, and maintain building projects throughout the lifecycle.

Creating a firm foundation for this game-changing AEC industry Scan to BIM (Building Information Modeling) stands out. At the intersection of traditional construction methods and evolving digitized solutions, the importance of Scanning and 3D modeling cannot be overstated.

This technique seamlessly integrates 3D laser scanning technology with advanced Buiding Information Modeling software. A digitized transformative process is facilitating the creation of accurate and detailed digital twins (replicas of existing structures), enabling architects, engineers, and construction professionals to collaborate to unlock a future with efficiency and excellence. In addition, there are informed decisions throughout the project lifecycle.

Overcoming construction lifecycle management traditional challenges of collaboration, integrated platforms, and manual errors the technology-driven environment streamlines a lot. Without a doubt no more horrors of documenting facilities and construction sites with a manual approach. 

The Pathway of Scan-to-BIM technology

Implementing Scan to 3D Modeling involves a structured roadmap to ensure a smooth and successful integration into construction and design processes. Its basic foundation depends on high proficiency 3D laser scanners like those from Leica. Eventhough, invented back in 1970s, the purpose of 3D scanners was not envisioned to the depth it has rooted itself today.

Initially, the project goal, scope, and deliverables are defined. Deliverables include defining the need for Scan to BIM implementation whether for renovation, new construction, or facility management. Tejjy 3D Laser scanning expert prefers a Leica scanner for accurate point cloud data. Adopting good quality 3D scanners facilitate cost and risk-controlled environments. No longer tracking progress, physical surveys, inspection, and mapping even in sensitive areas is possible.  

Processed raw point cloud data is converted into usable BIM models. Adopting Autodesk advanced software we implement quality control measures for accuracy during point cloud data registration. Seamless integration of scanned data into 3D model in existing workflow generates better collaboration. The integration allows us to identify and resolve clashes. 

When To Adopt Scan To BIM ?

But when should we implement Scan to BIM workflow? Let us delve into the stage of adoption of construction life cycle or facility management where a scan to 3D model should be integrated for improved ROI’s. 

Accurate land mapping and surveying

Architecture is the most commercial art form. You cannot assume conditions and events for design. However, that’s the case when you are not real with the land you are designing on. 

Challenge: The common process to record and map your land in today’s time is still very much reliant on inefficient site inspections and 2D-perspective drawings. 

Solution: The reality capture and then conversion of the captured data into BIMs (building information models) solves the very first stage of land mapping and surveying. Very accurate land maps in compatibility with geological data are possible with Leica’s RTC 360 and its information tag feature. 

Missing As-built data for Existing Buildings

As-built drawings reflect the true condition of a construction project. Conventionally, as-built drawings are made by site visits, manual taping, and one’s reflection of project progress. 

Challenge – Traditional as-built data collection and documentation can be time-consuming and could be costly for renovation or facility management. 

 Solution – By digitized point cloud data gathering, laser scan to 3D model technique minimizes the time needed for human measurements and site inspections. Slicing down on construction time and expenses by enabling early project completion.

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

Better Visualization from Scan To 2D

Accurate as-built documentation

If one opts for a 2D documentation approach to 3D as-built models, then it would be a subjective thing.A person or a group of people in some cases might not be able to make clear documentation outputs.

Challenge – Drawings miss level of detailing(LOD) and are not self explanatory. This can cause errors that could further increase the project progresses.

Solution – Point cloud data collection and registration captures accurate measurement of existing structures. Further ensuring, point cloud data to 3d model conversion. Scan to 2D can also be done but it misses clash detection features in visualization. So, we earn a benefit of cutting down rework and saving cost.

Streamlined Renovation and retrofitting

Scan-to-BIM technology is generally deployed for complete makeovers and space extension needs. In the first place, one needs to know the current situation of the space to make renovation and retrofitting decisions.

Challenge – Traditional documentation of buildings for renovating or retrofitting do not have precise data.

Solution – Scan-to-BIM data is captured and registered digitally that even replicas of same structure called digital twins can be created. As mobile data capturing scanners are available so renovation of small places to remote area with adverse physical condition can be addressed easily.

A whole new dimension of documentation

Traditional site documentation methods would be solely dependent on live sketching, textual reporting, and on-site measurements. It was just a limited use case for monitoring construction progress.

Challenge – Traditional methods may struggle with scalability, making it challenging to document large structures and projects with tight schedules or extensive scope.

Solution – Accurate and precise reality capture with the latest laser scanning technology and then converting the captured point cloud data into mesh models and building information models could be a first step to various scopes of work. Periodic laser scanning could be a great aid in the digital twinning process, as it would provide accurate project and facility conditions.

Construction Planning and Sequencing

Planning and sequencing leads to better management. The building management in a digitized manner gives streamlined flow.

Challenge – In traditional construction environment certain time deviations are not recorded. Certain misseing the progress track affect the schedules.

Solution – Scanning to BIM allows to monitor the deviation in design. As all updations in Revit are performed in real time so change management becomes easy. Easy alignment observation supports informed decision for all construction stages.

Efficient facility management

Facility management is all about managing the intersection of people, place, and purpose. And the backbone of facility management operations is monitoring each of the facility assets with total accuracy.

Challenge – Managing and maintaining facilities without updated information can result in inefficiencies and increased costs.

Solution – BIM models generated from laser scans serve as valuable tools for facility management. They provide accurate information about the building’s systems, components, and spatial relationships, aiding in maintenance planning and asset management.

Ensuring compliance with regulations

Architecture comes up with stringent standards and regulations to be followed. Especially in a time when climate change is a new concern and a growing population needs stricter management. 

Challenge – Ensuring compliance with building codes and regulations can be challenging without accurate, as-built data. 

Solution – The point cloud registration and then model development approach helps in creating models that adhere to regulatory requirements because scan to BIM ensures documentation in the truest sense. This further ensures that design and construction activities align with local building codes, reducing the risk of non-compliance issues. 

Energy efficency Analysis

Lack of knowledge hinders the implementation of energy efficiency measures. Additionally, there may be limited technical skills and expertise to manage and maintain energy-efficient systems. 

Challenge: A well-informed construction lifecycle requires a data-coordinated environment, which is totally not possible with out-dated methodologies. 

Solution: The point cloud registration and then model development approach helps in creating models that reflect the truth. With site conditions being digitized in their truest form, coordination can be streamlined for sustainable decisions. The whole feedback loop on sustainable development can be precise and accurate, especially in terms of how effective it is.

The scan to BIM technology may sound expensive upfront, but if you are thoughtful of your project, then a start with laser scanning and closure with BIM is a good investment. You are investing in technology to promise your client a process that is less erroneous and less labor-intensive.

You are indirectly hitting two birds here: the elimination of lower-quality work and discarding the contributing factors too. Investment in scan-to-BIM technology is all about investment in quality. Poor-quality work is very expensive in the long run, and in fact, you will realize a data-driven start would have made a good, thoughtful reality capture start.
