The use of digital twin technology – which creates a digital representation of the physical world – is becoming a key differentiator for firms in the AEC industry. In the wake of the COVID-19 lockdown, contractors face increasing demand for new facilities with sophisticated designs to accommodate retrofit requirements supporting a hybrid workforce. Digital twins can help throughout the planning, budget, design, and construction phases.
Construction is a complex sector with a variety of different stakeholders, including architects, engineers, contractors, building owners, and municipalities. Digital twins enable all of these groups to manage and share data, breaking down silos and improving decision-making across physical and departmental divides. Indeed, Forrester Research reports that 55% of global software technology decision-makers are already adopting digital twins, applying them to everything from design to maintenance.
What is a digital twin in construction?
Digital twins are used in construction projects to create exact replicas of real-world spaces. These 3D models allow construction teams to interact virtually with the physical property during the design and planning stages.
Digital twins give project teams immersive access to critical building intelligence in real time, which allows them to realize benefits in several key areas:
Faster and easier collaboration among project stakeholders
More efficient workflows between contractors and trades
Reduction of issues and RFI’s
By incorporating digital twins into the BIM (Building Information Modelling) process, contractors and AE firms can address many of the most pressing challenges in the industry, including low productivity, profitability, performance, and high error and accident rates. Digital twins in construction can also help firms reduce their virtual design and construction costs and, potentially, win more bids.
How digital twins work
Digital twins are created using a range of technologies, including 3D laser scanners, sensors, cameras, and other Internet-of-things (IoT) devices. There are three main stages involved in creating a digital twin:
Capture: First, digital twins can be captured with a variety of digital cameras, including the phone in your pocket. Using the Matterport app on your mobile device is an easy and affordable way to get started. Alternatively, you could use a number of compatible 360 pano-cameras to generate digital twins. And for jobs that require absolute precision, the Matterport Pro Series camera offers advanced scanning capabilities for both indoor and outdoor spaces.
Edit, document, and tag building assets: Use editing tools such as Blur and Tim to adjust your digital twin for clarity and security purposes. This enables easy and accurate visualizations of physical spaces, with measurements, and customizable areas.
Next, MatterTags and notes can be placed on the model to fortify data associated with specific assets that would be valuable in a handover package to an owner. For example, MSDS, warranty, and install PDFs can be uploaded and attached to a note placed on an air handler or other mechanical systems
Share and collaborate: You can share digital twin models with remote teams and offices, reducing the need for in-person site visits and cutting down on travel expenses, and supporting more environmentally-friendly business practices in AEC. This also allows far-flung teams to collaborate and coordinate more efficiently with accessible technology.
7 benefits of digital twins in construction
Offering a high degree of interoperability and automation, digital twins have the potential to revolutionize several aspects of the construction business. We will cover a few of the main benefits of digital twins in construction in this section.
1. Improved resource management
The use of digital twins can improve the procurement process and ease supply chain holdups, fostering harmonization between the current progress and future deliverables and helping construction firms better allocate resources and physical assets.
2. Easier communication with stakeholders
With Matterport software, project managers can export point cloud, OBJ files, high-resolution floor plans, and reflective ceiling plan views into 3ds Max, ReCap, Revit, and many others. This means stakeholders at every stage of the construction process can stay up-to-date on the latest advancements and red-flag any immediate concerns.
3. Better informed decision-making and planning
Digital twins are a proactive planning tool, allowing clients or building owners to provide feedback before the jackhammering begins or the sheetrock is installed. Engineers can also perform more extensive assessments for items like duct locations and utility placements, while architects can anticipate aesthetic concerns, such as paint color or lighting layouts. The use of digital twins empowers the improvement of design risk assessments and condition surveys, effectively enabling collaborators to shift away from PDF reports and photos by providing an immersive view to more effectively understand site conditions and issues.
4. Automated progress monitoringDocumenting progress is critical for any new construction project, and digital twins provide a way for managers to keep tabson projects from afar. General contractors and building owners require documentation to verify construction is progressing in line with standards and according to design. Good documentation also reduces errors and the need for rework. Comprehensive progress monitoring helps facilitate a successful end-of-project handoff from the construction team to facilities management.
5. More accurate assumptions and predictions
By eliminating the need for site visits while still providing a comprehensive overview of the built environment, managers can get faster and more accurate subcontractor estimates. They can also create virtual punch lists by annotating the 3D model with notes, links, photos, and videos.
6. Easier safety monitoring
Remote inspections allow project managers to better oversee safety procedures. Also, digital twins provide accurate, virtual measurements of hard-to-reach or dangerous environments, meaning employees don’t have to take unnecessary risks while on-site.
7. Robust handover deliverables for owners
Contractors who are using Matterport to collect existing conditions throughout the progress of a project and are then fortifying the model with embedded data tied to MEP systems—provide their owners with a digital handover package that allows them to manage the building on day 1.
Challenges of creating a digital twin for construction projects
To effectively deploy digital twins, some construction firms might have to overcome long-standing challenges in the industry. We will talk about the main challenges to be mindful of when implementing digital twins in construction in this section.
Lack of contractual awareness
Understanding the nuances of a contract is a fundamental aspect of any construction project, and the incorporation of new technology, like digital twins, can significantly alter the process. But by keeping a record of the project’s scope and the client’s key drivers, digital twins can aid in ensuring the requirements of a building contract are upheld and understood by all parties.
Lack of data understanding
Many construction firms experience challenges when trying to harness data effectively, struggling with a lack of capabilities to derive insights, employing disparate data management systems between IT and OT, and suffering from an inability to access data in real time or on tight deadlines. One of the advantages of Matterport is its easy integration with other data streams.
The move to BIM
Even now, many construction firms use 2D design technology for critical building projects. Leveraging a BIM model tied to a virtual design and construction process requires more complex 3D modeling technology and new skill sets within a firm.
No structure or defined SOPs
Some construction projects lack processes around data exchange and issue resolution, which makes the introduction of digital twins another hurdle for stakeholders to overcome. But by creating a single source of truth, digital twins make sure everyone – from contractors to inspectors to clients – is on the same page throughout a project’s lifecycle.
With so many budgetary demands to juggle, construction firms may be initially reluctant to spend on digital transformation. But the substantial savings as a result of reducing re-work, increasing effective collaboration, and minimizing travel expenses more than justify the investment.
Digital twin examples in construction
Many prominent architecture and construction firms have used digital twins to fundamentally change the way they approach projects. Here are a few stories from leading companies about how they realized the benefits of digital twins to improve their workflows.
