Plant Layout Plans Using 3D Laser Scans

Logan — Sun, 14 Jan 2024 02:36:38 +0000

In the dynamic world of manufacturing, maintaining or increasing efficiency throughout the evolution of a factory is paramount in a growing production business. This is where as-built plant layout plans and Building Information Models (BIM) are pivotal in helping line engineers and production managers. Knowing all of the exact measurements of your building and its installed equipment are not just tools for organization; they are necessary for calculated growth. The advent of 3D laser scanning has revolutionized how these layouts are captured and plans are created or updated. With the ability to expediently measure existing facilities with astounding accuracy, 3D laser scanning ensures that every square inch of a factory is accounted for, paving the way for seamless integration of new equipment and optimized use of space. Factories that use 3D scanning and as-built modeling firms have a competitive advantage over others, knowing exactly what equipment is installed where, and the ability to quickly configure the most efficient new layouts when new equipment or space is added.

Every Building Element And All Equipment At Your Fingertips

Using 3D scanning and as-built modeling we captured and drafted this manufacturing plant in Toronto complete with MEPF elements.

It All Starts With A 3D Scan

Using 3D laser scanning, we are able to quickly gather all the visual and measurement details required to develop as-built plant layout drawings. The 3D scan uses Terrestrial Laser Scanners (TLS) that measure every millimeter of an existing plant and its installed equipment. In addition to the measurement data, 360-degree photos are also taken to create a virtual tour. In most cases, the on-site capture process is non-invasive and doesn’t require a plant shutdown. Regular operations can be ongoing while the 3D scan is taking place.

The 3D scanning creates a pointcloud file, which contains all the spatial measurement data and 360-photos. This file can be kept offline by any project stakeholder and viewed as a virtual tour. Spot measurement can also be taken using the pointcloud file.

For this building survey, we used the Leica Geosystems BLK260 G2.

Then The As-Built Plans Are Created

With the pointcloud, all measurement and visual data is available to our architectural drafters remotely – so no secondary visits are required to develop accurate plant layout drawings.

In a well-developed Building Information Model (BIM), all architectural and structural building components are present. After adding the installed equipment all the plans can be created in CAD and PDF formats. We can export floorplans, reflective ceiling plans, elevations, and section drawings from a BIM.

The result is a clean plant layout complete with dimensions between walls and fixed equipment.

Enhanced Space Utilization

By providing a detailed and accurate view of the current factory layout, plant layout drawings enable engineers and production managers to identify underused areas or potential bottlenecks. This leads to smarter space planning, essential for accommodating new machinery or optimizing workflows.

Streamlined Communication and Planning

Together, the pointcloud file and detailed plans serve as a common language among different departments. Engineers, production managers, and maintenance teams can work in unison, as these plans offer a clear and comprehensive view of the factory’s current state and future upgrades. This synchronicity is crucial for minimizing downtime during expansions or reconfigurations.

Improved Safety and Compliance

Safety is paramount in factory settings. Detailed layout plans and BIM, developed through precise 3D scans, ensure that new installations comply with safety standards and regulations before installation takes place. They also help in creating safer workflows and emergency egress, enhancing overall workplace safety. As a quick example, even an unlevel floor from repetitious forklift use can cause unforeseen issues and injuries. With 3D laser scanning, floor levelness can be determined and addressed clearly and quickly.

Every Factory Should Be 3D Scanned

In essence, the integration of plant layout plans and BIM, empowered by 3D laser scanning, is not just about adapting to the present; it’s about future-proofing factories. It allows for a level of precision and foresight previously unattainable, fostering environments where innovation is not just possible but encouraged. For factories, this marks a significant leap towards operational excellence, ensuring they not only meet today’s demands but are prepared for tomorrow’s challenges.

The Power of Pointclouds: Electric Substation

Spencer — Sat, 17 Dec 2022 22:13:17 +0000

The Power of Pointclouds: Electric Substation

Critical infrastructure such as power plants and distribution stations can be complex and potentially hazardous. Many facility management and design professionals seek tools that allow for remote viewing and measurement to prioritize safety and efficiency. 3D laser scanning technology is one such property technology that produces point cloud files that provide millimeter-accurate representations of as-found conditions at electrical infrastructure sites. These files enable all project stakeholders to virtually walk and measure scanned areas from their offices, reducing the need for on-site personnel and expediting project designs and as-builts. Additionally, these point cloud files can be easily integrated into existing Revit or AutoCAD as-built workflows.

Safety And Efficiency Advancements

Facility managers and engineers are responsible for inspecting and maintaining critical infrastructure and buildings over time. This process often involves multiple site visits by multiple disciplines and may require further investigation once deficiencies are identified. Point cloud technology offers a more efficient and safer alternative by allowing for a single site visit to capture 360-degree photos and accurate measurements. This data can be used to create virtual tours of an electrical substation and detailed repair and maintenance plans, reducing the need for on-site personnel and minimizing the risk of injury.

The Right 3D Laser Scanner For The Job

There are various types of 3D laser scanners available on the market, each with different distance, speed, and accuracy capabilities. At Point3D, we use the Leica Geosystems line of 3D laser scanners and carefully select the most appropriate device for each project based on its complexity, size, and accuracy requirements.

Point Cloud Registration With Cyclone Register360

Spencer — Thu, 17 Feb 2022 02:02:26 +0000

Scans In, Pointclouds Out

In January 2022, Point3D was contracted to document the existing conditions of a commercial office building in Toronto, Ontario using 3D Laser Scanning. The project consisted of nearly 300 scan setups collecting millions of LiDAR measurement references, hundreds of 360-degree images, and infrared sensor data.

Each 3D scan was cleaned and registered with multiple links to ensure an accurate point cloud bundle. The combination of all 3D scans captured produced a dense, RGB-coloured point cloud providing a full understanding of the building’s dimensions and current condition. After registration was complete, a registration report confirmed the overall accuracy of the building spatial data. Essentially, this point cloud serves as a dimensionally accurate digital twin of the actual building.

Once digitally constructed, the final point cloud is exported into .RCP and .LGS file formats for both designers and non-technical project stakeholders to view. The video below shows the process of registering the 3D Laser Scan data in Leica Register360.

3D Laser Scanning

3D Laser Scanning is a reality capture method employed to measure the dimensions and geometry of existing structures more efficiently and accurately than traditional tools used for site measures. Put simply, 3D Laser Scanning helps to digitize the built environment. Millions of LiDAR measurement reference points and a 360-degree image are captured at the same time with every scan setup. Together, all as-built references, both dimensional and visual, are documented for further architectural and engineering analysis.

3D Laser Scan Registration

The dataset from each 3D scan setup must be registered to produce an accurate point cloud file. Best practices include having at least one link with another setup to ensure the best overall accuracy of the final point cloud file. This is completed with a combination of automatic and manual visual alignment. Scan data points are matched with those from other scans as accurately as possible. Typically, in a 3D scanning project, there are pre-registered and unregistered 3D scans, all of which are visually checked for proper registration during the final quality assurance process.

The benefits of introducing point clouds into the as-built development workflow are literally immeasurable.

For project delivery, the finalized or registered point cloud is typically made available in two formats. The first file format, .RCP, is specifically for professional architects and engineers. The second, .LGS, is a lightweight and easily accessible version of the point cloud which is accessible to almost anyone. While both formats are provided and can technically be opened for free (.RCP with Autodesk Recap, .LGS with Leica Truview), we have the following recommendation:

The .RCP point cloud: Used with the Autodesk suite of products including, but not limited, Autodesk Revit, Autodesk AutoCAD, and Autodesk Civil 3D. The point cloud along with Autodesk Recap Pro is used to create Building Information Models eliminating the need for repeat job site visits for measuring and modelling.
The .LGS point cloud: Preferred by some designers for use with measuring and visual confirmation of as-is building conditions, the .LGS file can be faster to load on most machines than Autodesk Recap. There are also additional features such as HDR images and IR-sensor information exclusive to the .LGS point cloud file. Also, it shouldn’t be discounted that the .LGS can be easily downloaded by any project or company stakeholder. The .LGS point cloud used with Leica Truview allows users to explore the point cloud similar to a virtual tour. This has proved to be an efficient way to receive boots-on-the-ground building intelligence without actually having to show up on site.

While .RCP and .LGS files are the most popular with our clients, Point3D is able to provide other industry standard formats such as .e57, .pts/.ptx, and .las, depending on the intended use downstream.

Why Point Clouds for As-Built Conditions?

By using point clouds captured with a calibrated laser scanning device and properly registered by a competent point cloud specialist, architects, engineers, and forward-thinking developers can efficiently produce accurate as-built drawings at scale. While an architect and apprentice can no doubt properly measure the existing conditions of a building, there exist many areas where major human-error can occur throughout the workflow. At scale, missed measurements, inaccurate measurements, and poor documentation practices can cause disaster to a project’s timeline. That’s why we are seeing more architects and developers in Toronto and Ottawa looking to Point3D Commercial imaging to promptly provide documentation by capturing point clouds with 360-images to produce Revit as-built models and AutoCAD as-built drawings. The benefits of introducing point clouds into the as-built development workflow are literally immeasurable.

We Visited Leica Geosystems Toronto

Spencer — Thu, 17 Dec 2020 04:02:52 +0000

Visiting Leica Geosystems Toronto

As a 3D laser scan service provider, we aim to provide the best and most practical 3D laser scanning solution. That’s why we visited Leica Geosystems in Toronto to learn about Leica Geosystems’ new device, the BLK2GO. We were able to pair this opportunity with some Matterport capture work in Toronto and stay the weekend. At Leica, we met with our favorite Leica Geosystems rep Tony Juteau and meet 3D enthusiasts, colleagues of all industries who also came to learn about the new laser scanner.

The Leica BLK2GO is a handheld mobile scanner that uses both visual SLAM and lidar SLAM, capturing 420,000 points per second using one of the world’s smallest dual-axis lidar. Using small but powerful panoramic cameras and a 12-megapixel detail camera, the point cloud files include RGB values and high-contrast imagery. The device expedites mobile survey capabilities, allowing spaces where time is sensitive and mobility is required.

During this training session with a not-yet-available Leica Geosystems Cyclone, we and other vendors were brought up to speed with the new import and registration functions of the program for the new device. This included new ways to clean the point cloud. As mobile laser scanning is fluid, it is more prone to the movement of people and objects in the scan. New tools in Leica Geosystems Cyclone Register360 allow for cleaning and filtering of the measurement references.

Using the device in the following demo confirmed that while a revolutionary device, it did not replace the Leica BLK360 in most environments. The resulting data is noisier and slightly less accurate than our terrestrial laser scanners so asbuilt modeling capabilities are limited. Of course, there is a right device for every job which we later had that warranted the mobile laser scanner.

We later used the Leica BLK2GO for a set of buildings that required expedited mobile laser scanning. The six complexes were comprised of 112 three-bedroom units that were tenantant just at the heights of the coronavirus COVID-19 virus. The scanning exercise could not be performed with a terrestrial laser scanner as the time spent in each unit needed to be limited. The resulting point clouds were registered and used to create Revit models of each building’s as-found conditions. The scanning accuracy of the laser scanner was 10mm-20mm and allowed for modeling accuracy of up to LOD300.

We also used the mobile laser scanner to capture large outdoor heritage sites like the Holocaust Monument in Ottawa.

Using 3d laser scanning data captured with mobile laser scanning, we modeled an asbuilt Revit model of a 20-unit building at an LOD of 300.
