With the digital boom in the AEC industry, the approach of professionals towards building projects has revolutionized. Scan to BIM services have emerged as an evolving technology transforming the construction fabric.
These services encompass the intricate process of transforming scanned data of existing buildings into highly detailed models.
The development of the construction sector from planning to execution is witnessed with the amalgamation of Scan to BIM Services and 3D BIM Modeling Services into a project. The elimination of lengthy processes, design intricacies, and well-organized work frames are the core benefits of Scan to BIM.
Understanding Scan to BIM services
Scan to BIM is a transformative process that uses a laser scanner to capture, document, and convert a physical space into a 3D model. The scanning process uses a laser scanner to capture every nuance of the construction site in the form of ‘Points’. The captured points are combined to form a point cloud presenting all the details about a building component.
The point cloud is further converted to a data-infused 3D model. The fundamental aim is to transform a physical space into a digital world that can be analyzed, manipulated, and leveraged throughout the building lifecycle. The Scan to BIM services are representative of the cutting-edge technology and revolutionization of 3D modeling.
How does the conversion of Scan to BIM take place?
- Data capturing is the first step in the process in the form of multiple scans and images, using laser scanners.
- The scanned data is documented as Point clouds, further examined and analyzed.
- After the precise data scanning and examination, it is fed into software like Revit for converting it into a 3D model.
- A thorough check is conducted to ensure the data quality and make amendments if required.
- Developing the final 3D model, referred for project execution on the site by the project team.
Industry Applications of Scan to BIM Services
The architecture industry extensively engages in Scan to BIM services for three-dimensional space inspection, documentation of as-built structures, site analysis, space optimization, and 3D modeling. The architecture professionals explore its benefits and incorporate the services, uplifting project quality and accuracy.
2. Building Construction
The major feature of Scan to BIM services is the way it captures every minute site detail from every possible angle and documents it together to craft a 3D model.
The construction professionals harness this benefit to do a detailed site study and initiate a transparent discourse within the construction team. Scan to BIM in the construction industry also helps in structural analysis, coordination, deformation control, progress monitoring, and repair estimates.
3. Heritage Conservation
The use of laser scanning for site analysis and conversion to a 3D model comes in handy for the Heritage conservation industry as well. For reconstruction, restoration, and refurbishment projects, Scan to BIM is an advantageous approach that reduces manual work with cost and time savings.
4. Facility Management
Facility management uses Scan to BIM for documenting and planning structural changes. The walkthrough or video fly-throughs enable the facility managers to run through the usage options for different spaces before the design process starts.
Advantages of Scan to BIM services
- Ease of documenting data
3D laser scanners collect millions of data points within seconds, speeding up the data documentation. The comprehensive documentation of data generated through Scan to BIM services works in compliance with the building codes and standards. It provides access to the building’s history and construction details, which is invaluable for legal purposes.
- Increased accuracy
Traditional manual surveying methods were used before the development of BIM modeling services. Those methods were time-consuming and produced inaccurate results due to human error. 3D laser scanning reduces the extent of human error, as it eliminates human involvement. The accuracy of 3D BIM Modeling services is unmatched, reducing discrepancies, and errors in a project execution.
- Ease of dealing with complex forms and designs
Handling enormous and tricky building designs is part of the Scan to BIM process. The construction projects deal with every kind of shape and form, making the execution a tedious job for the designer and the construction team. The 3D model drives the construction process for such buildings, simplifying the handling and execution.
- Creating 3D virtual assets
The project details are documented in the form of a point cloud and these point cloud 3D models generate 3D virtual assets. These assets are further used for feasibility studies and collision checks with other elements. Construction simulation is also geared toward 3D virtual assets.
- Generation of a digital twin
The digital twin is a highly complex and exact virtual replica of a building or a component. With connected sensors of the building, the data maps out the entire building lifecycle from inception to demolition with maximum accuracy. The Scan to BIM services create such digital twins of an object or a structure.
- Reduced site visits
A digital representation of the project allows the stakeholders to analyze the site without recurring site visits. It saves traveling time and effort of the team assigned to the project. Especially, in the case of a remote site, design professionals can save time from site visits and invest it in research, conceptualizing, and planning.
- Savage of cost and time
Scan to BIM services identify clashes or conflicts before construction starts, contributing to significant cost and time savings. It eliminates the need for unnecessary on-site capital investment in modifications or reworking.
- Reduce safety hazards
Laser scanners collect data from hard-to-reach spaces on a site or dangerous locations without putting surveyors at risk. For instance, in hazardous areas like sewers, instead of risking a person’s life, scanners can be used in the pits.
Challenges and Limitations
Scan to BIM has certain limitations similar to any emerging process. Here are a few challenges and limitations that need to be addressed for any construction project.
1. Collaboration requirement
Scan to BIM is an iterative process, requiring the client’s involvement at every stage. Proper communication and collaboration are imperative. Frequent dialogues with the client are necessary to agree on a specific Level of Detail(LOD).
2. Software Limitations
The majority of BIM software, including Revit, is designed to create new buildings and not deal with already existing structures. The lack of these features makes it difficult to document the project effectively.
3. Limitations of the Weather
The weather limitation is another considerable factor while conducting the Scan to BIM process. It cannot be conducted outdoors in extreme weather conditions.
4. Scale of the project
For large-scale projects, the scanner is supposed to capture a large amount of data. The processing of this data will require adequate computing power and storage options.
5. Busy Areas
The scanning procedure requires a space for seamless execution without errors or conflicts. This becomes difficult in places that are busy and difficult to tackle.
Scan to BIM services have emerged as a transformative technology in the AEC industry, revolutionizing the way construction projects are planned and executed.
The process, involving the use of 3D laser scanners to capture and convert physical spaces into detailed digital models, brings a myriad of benefits to various sectors such as architecture, construction, heritage conservation, and facility management.
The advantages of Scan to BIM services are evident in the ease of data documentation, increased accuracy, handling complex designs, creating 3D virtual assets, generating digital twins, reducing site visits, and ultimately saving costs and time.
However, challenges such as collaboration requirements, software limitations, weather constraints, scalability, and dealing with busy areas need to be addressed to fully harness the potential of this technology.
