Technologies like augmented reality in construction are emerging to digitalize the construction industry, making it significantly more effective.
What if we could have instant access to all the information about a construction site, down to smallest details about every person, tool, and bolt? What if we could always be sure about the final measurements of a beam or that soil volumes in the cuts are close to those of the fills? What if we could always track how fast the supply of materials runs out, and re-order supplies automatically?
All this is achievable with a digital twin — a concept of having a real-time digital representation of a physical object.
The following are some real-time digital twins applications on construction sites.
Automated Progress Monitoring
Progress monitoring verifies that the completed work is consistent with plans and specifications. A physical site observation is needed in order to verify the reported percentage of work done and determine the stage of the project.
By reconstructing an as-built state of a building or structure we can compare it with an as-planned execution in BIM and take corresponding actions to correct any deviations. This is usually done by reconstructing geometry of a building and registering it to the model coordinate systems, which is later compared to an as-planned model on a shape and object level.
Often data for progress monitoring is collected through the field personnel and can be hugely subjective. For example, the reported percentage of work done can be faster in the beginning and much slower close to the end of the project. People are often initially more optimistic about their progress and the time needed to finish the job.
Hence, having automated means of data collection and comparison means that the resulting model to as-designed BIM models is less liable to human error. Digital twins solve the common construction process problems.
As-Built vs As-Designed Models
With a real-time digital twins, it is possible to track changes in an as-built model — daily and hourly. Early detection of any discrepancies can lead to a detailed analysis of historical modeling data, which adds an additional layer of information for any further decision-making processes.
The project manager can then reconstruct the steps that led to the error and make changes in the future work schedule in order to prevent any similar mistakes from occurring. They can also detect under-performers and try to fix the cause of the problem earlier in the project or plan the necessary changes to the budget and timescale of the whole project.
Resource Planning and Logistics
According to the Construction Industry Institute, about 25% of productive time is wasted on unnecessary movement and handling of materials.
Digital twin technology provides automatic resource allocation monitoring and waste tracking, allowing for a predictive and lean approach to resource management. With digital twin technology companies would avoid over-allocation and dynamically predict resource requirements on construction sites, thus avoiding the need to move resources over long distances and improving time management.
The construction industry is one of the most dangerous sectors in the world. According to the Bureau of Labor Statistics in the United States, more than four thousand construction workers died on-site between 2008 and 2012.
The real-time site reconstruction feature digital twins allows the industry’s companies to track people and hazardous places on a site, so as to prevent inappropriate behavior, usage of unsafe materials, and activity in hazardous zones. A company can develop a system of early notification, letting a construction manager know when a field worker is located in dangerous proximity to working equipment and sending a notification about nearby danger to a worker’s wearable device.
Microsoft recently shared a great vision of how AI combined with video cameras and mobile devices can be used to build an extensive safety net for the workplace.
Image-processing algorithms make it possible to check the condition of concrete through a video or photographic image. It is also possible to check for cracks on columns or any material displacement at a construction site. This would trigger additional inspections and thus help to detect possible problems early on.
See an example of how 2D images using 3D scene reconstruction can be used for concrete crack assessments.
Optimization of Equipment Usage
Equipment utilization is an important metric that construction firms always want to maximize. Unused machines should be released earlier to the pool so others can use them on other sites where they are needed. With advanced imaging and automatic tracking, it is possible to know how many times each piece of machinery has been used, at what part of the construction site, and on what type of the job.
Monitoring and Tracking of Workers
Some countries impose tough regulations on how to monitor people presence on a construction site. This includes having a digital record of all personnel and their location within the site, so that this information could be used by rescue teams in case of emergency. This monitoring is another digital twins application. Still, it is better to integrate digital twin-based monitoring with an automatic entry and exit registration system, to have a multi-modal data fused into a single analytics system.
Getting Data for Digital Twins
Some ways to gather data to be used for digital twins includes the following:
- Smartphone Cameras
- Time-Lapse Cameras
- Autonomous UAV and Robots
- Video Surveillance Cameras
- Head-mounted Cameras and Body Cameras
Image data processing algorithms for digital twins can be created with the following methods:
- 3D Reconstruction: Conventional Photogrammetry
- 3D Reconstruction: Structure from Motion
- Object Detection and Recognition
- Object Tracking
From an Investor’s Viewpoint
On projects to date, this approach has proven to save time, reduce waste and increase efficiencies.
From a Standardization Proponent’s Viewpoint
Open, sharable information unlocks more efficient, transparent and collaborative ways of working throughout the entire life-cycle of buildings and infrastructure.
From a Solution Provider’s Viewpoint
While the digital twin is needed initially for planning and construction, it’s also intended to provide the basis for building operations moving forward.
The vision of “construction 4.0” refers to the 4th industrial revolution and is a fundamental challenge for the construction industry. In terms of automated production and level of digitalization, the construction industry is still significantly behind other industries. Nevertheless, the mega-trends like Big Data or the Internet of Things offer great opportunities for the future development of the construction sector. Prerequisite for the successful Construction 4.0 is the creation of a digital twin of a building. Building Information Modeling (BIM) with a consistent and structured data management is the key to generate such a digital building whose dynamic performance can be studied by building simulation tools for a variety of different boundary conditions.
Along the total life cycle from design to construction, operation and maintenance towards remodeling or demolition, the digital twin follows all modifications of the real building and dynamically readjusts itself in case of recorded performance differences.
Thus, for the whole life span of the real building, performance predictions generated with the virtual twin represent an accurate basis for well-informed decisions. This helps to develop cost-effective operation modes, e.g. by introducing new cyber-controlled HVAC systems. The digital twin may also analyze the building’s dynamic response to changes in occupation or energy supply; it also indicates the need for building maintenance or upgrades.
