The significance of BIM lies in its ability to facilitate collaboration, reduce errors, and improve project outcomes. It enables architects, engineers, contractors, and other stakeholders to work on a shared platform, making it easier to detect and address potential issues before they become costly problems during construction.

2. The Challenge of PDF Documents

While BIM has become the industry standard for project planning and execution, many architectural plans, and designs are still presented in the Portable Document Format (PDF). PDFs have been widely used for their compatibility and ease of sharing, but they lack the intelligence and interactivity that BIM offers. This separate between PDF documents and BIM technology can lead to inefficiencies in the design and construction process. Architects and contractors often find themselves manually transcribing information from PDF into BIM software, a time-consuming and error-prone task. As a result, there is a growing demand for solutions that can bridge the gap between these two formats.

3D Laser Scanning – Types | Benefits | Applications

3D laser scanning services by BIMPRO LLC for precise building measurements

3D Laser Scanning

3D laser scanning techniques have been developed since the end of 1990s for 3D digital measurement, documentation and visualization in several fields including 3D design in processing industry, documentation and surveying in architecture and infrastructure. By using a 3D laser scanner, a tunnel or underground construction can be digitized in 3D with a fast-scanning speed and high resolution up to “mm” level. 

The scanning data consists of not only XY-Z co-ordinates but also high-resolution images, either gray-scale (with reflex intensity data) or color (with RGB data), and then can be transformed into a global co-ordinate system by control survey. Therefore, any rock engineering objects with its as-built situation can be quickly recorded as the 3D digital and visual format in a real co-ordinate system and provides a potential application for 3D measurement, documentation and visualization with high resolution and accuracy.

In modern engineering the term ‘laser scanning’ meaning is the controlled steering of laser beams followed by a distance measurement at every direction. This method, often called 3D object scanning or 3D laser scanning, is used to rapidly capture shapes of objects, buildings, and landscapes.

What is 3D Laser Scanning?

3D laser scanning is a non-destructive, non-contact method of capturing data that can be used for rapid and accurate creation of three-dimensional files, for archiving and digital manipulation. A 3D laser scanner emits a narrow laser beam that hits a target object, gathering millions of closely spaced measurements in a matter of minutes. These scanned measurements are put together and grouped into compressed point cloud databases, which can be processed to generate a 3D dense representation of the object.

3D Scanners Bridging Physical and Digital Worlds

3D scanners are tri-dimensional measurement devices used to capture real-world objects or environments so that they can be remodeled or analyzed in the digital world. The latest generation of 3D scanners do not require contact with the physical object being captured.

3D scanners can be used to get complete or partial 3D measurements of any physical object. The majority of these devices generate points or measures of extremely high density when compared to traditional “point-by-point” measurement devices.

How 3D Scanning Works?

Scanning results are represented using free-form, unstructured three-dimensional data, usually in the form of a point cloud or a triangle mesh. Certain types of scanners also acquire color information for applications where this is important. Images/scans are brought into a common reference system, where data is merged into a complete model. This process — called alignment or registration — can be performed during the scan itself or as a post-processing step.

Computer software can be used to clean up the scan data, filling holes, correcting errors and improving data quality. The resulting triangle mesh is typically exported as an STL (STereoLithography or Standard Tessellation Language) file or converted to Non-uniform Rational B-Spline (NURBS) surfaces for CAD and BIM modeling.

Types of Laser Scanning

1. Airborne Laser Scanning (LiDAR)

Airborne laser scanning (LiDAR = acronym for ‘Light detection and Ranging’, also LIDAR) is a scanning technique for capturing data on the features of, and objects on, the surface of the earth. It is an important data source in environmental studies, since it is capable of mapping topographic height and the height of objects on the surface to a significant vertical and horizontal accuracy, and over large areas. Airborne laser scanning is an active remote sensing technology able to rapidly collect data from vast areas.

2. Terrestrial Laser Scanning

Terrestrial Laser Scanners (TLS) are positioned directly on the ground, or on a platform placed on the ground, and are normally mounted on a tripod. TLS is, in its essence, an improved version of the laser tachometric measurement toolkit (the so-called total station) that is based on the combination of distances and angles measured from a fixed point. Tachometric laser scanners digitize objects of interest with a frequency of 1000 Hz or higher. Each point is measured per one oblique distance and, additionally, two orthogonal angles are measured. Most TLS are long-range devices. Nowadays, a great variety of TLS is available with different range and pulse frequencies.

3. Handheld (portable) Laser Scanning

There has recently been an increase in the application of handheld scanners. Their basic advantage is their portability. Scanners that are attached to light portable stands fall in this category as well, even though they are not ‘handheld’ in the true sense of the word. Primary used in reverse engineering, nowadays they are very often employed in digital documentation of moveable cultural heritage objects.

4. Long- and Short-Range Laser Scanning

Long-range laser scanning is tailored for surveying and monitoring expansive areas or structures. Using high-powered lasers and advanced optics, it covers distances from yards to miles/meters to kilometers. Employing time-of-flight or phase-based technologies, it finds applications in geological surveys, urban planning, infrastructure monitoring, and archaeological site mapping.
Short-range laser scanning focuses on high-precision tasks within confined spaces. Covering distances from centimeters to meters/ feet to yards, it utilizes structured light or laser triangulation. Widely used in industrial metrology, 3D scanning, quality control, and cultural heritage preservation, it excels in capturing fine details with accuracy.

3D Scanning File Formats

When integrated with building information modeling (BIM), laser scanning helps identify clashes between design plans and existing structures, reducing costly construction errors.

Applications of 3D Laser Scanning

3D Laser Scanning is used in numerous applications:  Industrial, architectural, civil surveying, urban topography, reverse engineering, and mechanical dimensional inspection are just a few of the versatile applications. 3D laser scanning technology allows for high resolution and dramatically faster 3D digitizing over other conventional metrology technologies and techniques.  Some very exciting applications are animation and virtual reality applications.

1. Construction Industry and Civil Engineering

a. As-built drawings of bridges, industrial plants and monuments b. Documentation of historical sites c. Site modelling and lay outing d. Quality control e. Quantity surveys f. Freeway redesign g. Establishing a benchmark of prre-existing shape/state in order to detect structural changes resulting from exposure to extreme loadings such as earthquake, vessel/truck impact or fire. h. Create GIS (Geographic Information System) maps and Geomatics

2. Reverse Engineering

Reverse Engineering refers to the ability to reproduce the shape of an existing object. It is based on creating a digitized version of objects or surfaces, which can later be turned into molds or dies. It is a very common procedure, which has diverse applications in various industries. Non- contact 3D laser scanning allows even malleable objects to be scanned in a matter of minutes without compression, which could change their dimensions or damage to their surfaces. Parts and models of all sizes and shapes can be quickly and accurately captured. 3D laser scanning for reverse engineering provides excellent accuracies and helps to get products to market quicker and with less development and engineering costs. 3D Laser scanning provides the fast, accurate, and automated way to acquire 3D digital data and a CAD and BIM model of part’s geometry for reverse engineering when none is available. Also, new features and updates can be integrated into old parts once the modeling is accomplished. A practical mechanical and civil engineering application would be to assist in the production of "as built" data and documentation. Currently, many manufacturing or construction activities are documented after the actual assembly of a machine or civil project by a designer or engineering professional. 3D laser scanners could expedite this activity to reduce man-hours required to fully document an installation for legacy.

3. Mechanical Applications

Reverse engineering of a mechanical component requires a precise digital model of the objects to be reproduced. Rather than a set of points a precise digital model can be represented by a polygon mesh, a set of flat or curved NURBS surfaces, or ideally for mechanical components, a CAD solid model. A 3D scanner can be used to digitize free-form or gradually changing shaped components as well as prismatic geometries whereas a coordinate measuring machine is usually used only to determine simple dimensions of a highly prismatic model. These data points are then processed to create a usable digital model, usually using specialized reverse engineering software.

4. Civil Applications

Civil activities could be for a roadway periodic inspection. The digitized roadway data could be contrasted to previous roadway 3D scans to predict rate of deterioration. This data could be very helpful in estimating roadway repair or replacement costing information. When personnel accessibility and/or safety concerns prevent a standard survey, 3D laser scanning could provide an excellent alternative. 3D Laser scanning has been used to perform accurate and efficient as-built surveys and before-and after construction and leveling survey.

5. Design Process

Design process including: a. Increasing accuracy working with complex parts and shapes b. Coordinating product design using parts from multiple sources c. Updating old CD scans with those from more current technology d. Replacing missing or older parts e. Creating cost savings by allowing as-built design services, for example: automotive manufacturing plants. f. “Bringing the plant to the engineers” with web shared scan and saving travel costs.

Conclusion

3D laser scanning equipment senses the shape of an object and collects data that defines the location of the object’s outer surface. This distinct technology has found applications in many industries including discrete and process manufacturing, utilities, construction. Laser scanning technology has matured and developed in the past two decades to become a leading surveying technology for the acquisition of spatial information.

The high-quality data produced by laser scanners are now used in many of surveying’s specialty fields, including topographic, environmental, and industrial. These data include raw, processed, and edited dense point clouds; digital terrain and surface models; 3D city models; railroad and power line models; and 3D documentation of cultural and historical landmarks. 3D laser scanners have a wide range of applications which applicable to very small object to a wide range area.

BIM LOD (Level of Development) – LOD100 | 200 | 300 | 350 | 400 | 500

BIM LOD (Level of Development) – LOD100 | 200 | 300 | 350 | 400 | 500

BIM LOD (Level of Development).

This BIM LOD (Level of Development) blog seeks to address the concept and understanding about LOD in AEC industry with clear guidance on its origin, definition and benefits.

What is LOD (Level of Development)?

The concept of “Level of Development” (LOD) aims to tackle the challenge that certain model elements progress at varying speeds throughout the design phase. LOD provides a way to describe the progressive growth of specific model elements from the idea stage to actualization. The metric of LOD allows for a more precise definition of project deliverables. As a widely accepted industry standard, it facilitates effective communication and collaboration among project stakeholders.

History of LOD?

The American Institute of Architects (AIA) developed the concept further in AIA Document E202 – 2008 Building Information Modeling Protocol Exhibit. It includes this definition:

“The Level(s) of Development (LOD) describes the level of completeness to which the model element is developed.”

It outlines a model element’s logical progression from the initial conceptual approximation stage to the final level of representation precision. The document establishes five distinct Levels of Development, ranging from 100 to 500. Each succeeding level is constructed on top of the previous one, resulting in a hierarchical structure.

The definition of LOD was amended in AIA draft document G202-2012 Building Information Modeling Protocol Form to the following:

“The Level of Development (LOD) describes the minimum dimensional, spatial, quantitative, qualitative, and other data included in a model element to support the authorized uses associated with such LOD.”

The BIMForum Level of Development specification authors recognized a necessity for a specific LOD that would adequately describe model components to enable coordination between various disciplines, such as clash detection and avoidance. Although the standards for this level surpass LOD 300, they are not as demanding as those for LOD 400. Consequently, the authors assigned the designation LOD 350 to this particular level.

What is BIM (Building Information Modeling)?

BIM (Building Information Modeling) is a digital representation of the physical and functional characteristics of a building or infrastructure project. BIM is a process that involves creating and managing digital models of a project’s design, construction, and operation, which can be used for decision-making throughout the project’s lifecycle.

BIM models typically contain 3D geometry, as well as data and information about the building’s components and systems, such as mechanical, electrical, plumbing, and structural systems. BIM models can also include data about cost, schedule, sustainability, and other important project information.

BIM LOD (Level of Development)

BIM LOD is a measure of the completeness and accuracy of the information contained in a BIM model for a particular building element or system. The level of detail required for a BIM model can vary depending on the intended use of the model. The level of development required for a BIM model will depend on the stage of the project and the needs of the stakeholders involved.

There are typically five levels of development that are used to describe the level of completeness and detail of a BIM model.

The LOD 100, 200, 300, 400 and 500 definitions are produced by the AIA (The American Institute of Architects) and LOD 350 was developed by the BIMForum working group.

LOD 100: Conceptual

The model element may be graphically represented in the model with a symbol or generic representation, but does not satisfy the requirements for LOD 200. Information related to the model element (i.e. cost per square meter, etc.) can be derived from other model elements.

BIM LOD 100

LOD 200: Approximate Geometry

The model element is graphically represented in the model as a generic system, object or assembly with approximate quantities, size, shape, location, and orientation.
Non graphic information may also be attached to the model element.

BIM LOD 200

LOD 300: Precise Geometry

The model element is graphically represented in the model as a specific system, object, or assembly accurate in terms of quantity, size, shape, location, and orientation.
Non graphic information may also be attached to the model element.

BIM LOD 300

LOD 350: Connection Details

The model element is graphically represented within the model as a specific system, object, or assembly in terms of quantity, size, shape, location, orientation, and interfaces with other building systems. Non-graphic information may also be attached to the model element.

LOD 400: Fabrication

The model element is graphically represented in the model as a specific system, object, or assembly accurate in terms of quantity, size, shape, location, and orientation with detailing, fabrication, assembly and installation information.
Non graphic information may also be attached to the model element.

BIM LOD 400

LOD 500: As-built

The model element is field verified representation accurate in terms of size, shape, location, quantity, and orientation.

BIM LOD 500

Benefits of LOD (Level of Development)

There are several benefits of LOD (Level of Development) in construction and design projects, including:1

1) Standardization: LOD standards created by AIA and BIMForums provides a common understanding that helps to improve communication and collaboration among project stakeholders.

2) Clarity: It provide clarity for the level of information required at the different design stages that helps to avoid misunderstandings and confusion.

3) Improved Coordination: LOD helps to improve coordination among different disciplines by specifying the level of detail required to facilitate clash detection and other coordination tasks.

4) Early Issue Identification: By defining the expected level of detail and accuracy at each stage, LOD can help to identify potential issues early on in the design and construction process.

5) Improved Quality: By specifying the expected level of detail and accuracy at each stage, LOD helps to improve the quality of the project deliverables.

6) Reduced Costs: By identifying potential issues early on in the process, LOD can help to reduce the cost of rework and other remedial measures.

7) Better Decision-making: By providing a clear framework for project delivery, LOD helps project stakeholders to make better decisions.

Conclusion

Main aim of BIM based LOD is to establish a convenient decision-making method during the early design stages. Investing more time in design stage and utilize LOD and its requirements consistently, would enhance the level of information and detail in BIM Objects. In conclusion BIM based LOD is essential for successful project delivery. It provides a standardized approach to design and construction, facilitates collaboration and communication among project stakeholders, and helps identify and address potential issues early on in the process.
