The construction industry is undergoing a technological and digital transformation, and one of the evolving and emerging technologies are in the area of reality capture including drone (UAS) photogrammetry and aerial LiDAR. Both technologies offer unique advantages in capturing high-quality data for construction projects, making them invaluable tools for modern AEC (Architecture, Engineering, and Construction) professionals.
What are Drone Photogrammetry and Aerial LiDAR?
Drone Photogrammetry
Photogrammetry is the science of making measurements from photographs. Drone photogrammetry involves capturing aerial photographs using drones, which are then processed to create 3D models or maps. There are several technology vendors such as Pix4D, Autodesk, DJI, and others.
Aerial LiDAR
LiDAR (Light Detection and Ranging) is another remote sensing technology that uses laser pulses to measure distances to the Earth's surface. When mounted on drones, LiDAR can produce highly accurate topographical maps and 3D models. I have worked with a few vendors with hardware on projects in the field such as the technology pioneers CSIRO & Emesent and FARO.
Speed and Efficiency
Traditional manned aerial surveying methods can be labor-intensive and time-consuming. Both drone photogrammetry and aerial LiDAR offer rapid data collection, covering large areas in a fraction of the time it would take using conventional methods. This speed is particularly beneficial in the early stages of construction, where time is often a critical factor.
Cost-Effectiveness
While the initial investment in drone technology and software can be substantial, the long-term cost benefits are significant. By reducing the man-hours required for surveying and data collection, both drone photogrammetry and aerial LiDAR can lower the overall cost of construction projects.
Enhanced Accuracy
Both technologies are known for their high level of accuracy. Drone photogrammetry uses high-resolution cameras to capture detailed images, while aerial LiDAR provides extremely precise measurements. These data sets can be integrated into BIM (Building Information Modeling) software, offering a comprehensive and accurate view that aids in design, planning, and construction.
Safety
Construction sites often present various hazards, from heavy machinery to uneven terrain. Drones equipped with photogrammetry or LiDAR can safely capture data in areas that may be dangerous or difficult for human surveyors or manned aircraft to access, thereby enhancing overall site safety.
Real-Time Monitoring and Updates
Both drone photogrammetry and aerial LiDAR can provide near real-time data, allowing project managers and stakeholders to monitor progress and make immediate, data-driven decisions. This capability is invaluable for keeping projects on schedule and within budget.
Complementary Technologies
While both drone photogrammetry and aerial LiDAR are powerful on their own, they can also be used in tandem for even more robust data collection. The combination of these technologies can offer a comprehensive data set that meets the diverse needs of construction projects.
Drone photogrammetry and aerial LiDAR are not just technological novelties; they are essential tools that are reshaping the construction industry. Offering speed, cost-effectiveness, and accuracy, these technologies are becoming indispensable for modern construction projects. As they continue to evolve, their applications and capabilities are likely to expand, solidifying their role as must-have tools for AEC professionals. It is exciting to see how construction and surveying teams use these new technologies and the future evolution to deploy fully Ai autonomous data collection and site monitoring.
So the next time you see a drone buzzing overhead at a construction site, remember that it's doing much more than capturing cool photos—it's helping to build the future, one data point at a time.
In a world where rapid urbanization and technology go hand in hand, construction methods constantly evolve and technology disruptions are occurring daily. One increasing development is industrialized construction (IC) where there is a convergence of manufacturing and AEC.
But what exactly is it?
Industrialized construction refers to the application of manufacturing techniques in the building process. This method allows for building components' design, fabrication, and assembly to be carried out in a controlled factory environment rather than on-site.
Why is it Important?
How Does it Work?
Typically, the process starts with digital modeling to create precise plans and models. These digital designs are then used in automated factories to produce prefabricated components, such as walls, floors, and roofs. Once manufactured, these parts are transported to the construction site for quick assembly, similar to assembling a large-scale jigsaw puzzle.
Industrialized construction presents a way of building that offers increased efficiency, enhanced quality, and a more sustainable approach to construction.
Conclusion
Industrialized construction presents a way of building that offers increased efficiency, enhanced quality, and a more sustainable approach to construction. As technology continues to advance, this method is likely to become even more prevalent, setting a new standard for the industry.
Whether you're a contractor, an architect, an engineer, a developer, or someone simply interested in the evolution and innovation of construction methods, it's an interesting and exciting time to be involved in the field.

The Architecture, Engineering, and Construction (AEC) sector is experiencing a transformative digital shift, thanks to Artificial Intelligence (AI). From design conception to construction management, AI has found applications across a myriad of tasks. Let's explore some key ways AEC firms can utilize AI.
Design Optimization
AI algorithms can sift through complex data sets to recommend the most efficient design layouts. By analyzing factors such as sunlight, wind direction, form, and material strength, AI can offer eco-friendly and cost-effective designs.
Predictive Maintenance
Utilizing sensor data, AI can predict when machinery or a structural component is likely to fail. This proactive approach ensures timely maintenance, saving both time and money.
Construction Automation
Robots equipped with AI can automate repetitive tasks like bricklaying or painting. This not only accelerates the construction timeline but also reduces human error.
Resource Allocation
AI can help in optimizing resource distribution by analyzing a wide array of variables, such as manpower, materials, and budget, to ensure the best allocation for maximum efficiency.
Safety Monitoring
Through computer vision, AI can monitor job sites in real-time to identify safety hazards, such as workers not wearing helmets or stray equipment, and notify concerned authorities immediately.
Post-Construction Analysis
AI can continue its role even after the construction is completed, providing insights into how a building's performance aligns with its initial design goals, thus creating a feedback loop for future projects.
The integration of AI technologies in AEC practices promises to improve efficiency, safety, and overall project success. As the technology matures, it's poised to become an indispensable tool much like spreadsheet and CAD applications for AEC firms looking to stay competitive in the digital age.
In the ever-evolving and rapid digitization of the world of Architecture, Engineering, and Construction (AEC), the importance of location-based data and spatial analytics cannot be understated. Geographic Information Systems (GIS) have increasingly become an important strategic component, offering a vital competitive edge for AEC firms.
