The AEC industry has been known as a technology adopter over the past decade. The COVID-19 pandemic accelerated adoption across the value chain. Contractors, architects, project coordinators and other onsite professionals are now looking for ways to improve efficiency, optimize costs, reduce construction time, increase safety standards and improve sustainability metrics. Technology is the answer to their quest.
Building Information Modeling (BIM)
Building Information Modeling (BIM) is a process that helps us create 3D models, which are digital representations of the physical and functional features of a building/structure. It is a step to change the performance of any project. Real-time visualization of the project through BIM models allows stakeholders to be updated and saves a significant amount of time and resources. A cloud-based model makes access to project information location and time agnostic. This informational transparency of design and project management promotes better collaboration and conflict resolution between project teams and faster project completion. If the full potential of 3D to 8D BIM is exploited, construction Projects will exceed their current performance levels in terms of time, cost, materials, safety and sustainability.
Digital Reality Capture
Countries around the world suffer from dilapidated infrastructure. Most of these are only 2D physical documents as an information source for renovation planning in old structures. Changing these blueprints manually is difficult and time-consuming. That's when technology like Digital Reality Capture comes as a boon. Digital reality capture refers to the process of scanning a physical asset to create a 3D digital representation of a building. Laser scanning or photogrammetry is used to measure various points on the surface and other elements of the building.To produce an accurate 3D model. The data obtained through this process provides information about the location of existing assets. This makes it easier for architects and engineers to plan renovations, detect conflicts early, and make better decisions in design and resource use. Digital Reality Capture is an accurate survey technology for small and large infrastructure, including accident-prone areas. It reduces labor, saves time, and ensures worker safety.
Automation
Many construction companies are adopting automation technologies for labour-intensive, time-consuming and risky tasks. From the planning stage to on-site construction to post-construction asset management, automation of tasks across the entire construction lifecycle is now possible. For example, automated or self-propelled trucks and forklifts can help move construction materials to the construction site, thereby saving time and effort.
Another effective tool is the drone that can be used for pre-construction surveys. It can also be used to monitor the site during the construction phase to identify potential hazards. Similarly, there are IoT (Internet of Things) based sensors that collect real-time data such as location, pressure, temperature and other aspects for various devices from the building during the operation phase. Machines can be automated based on this data. For example, fabrication and welding machines can be automated with specific processes based on signals received from sensors.
Virtual reality and augmented reality are some of the more powerful examples of automation in the AECO industry. In virtual reality, 3D scanned images are used to create a simulated building environment. It facilitates site walkthroughs that help architects and other project stakeholders plan construction. It can also simulate dangerous situations like fire or natural disasters to help project members with preventive maintenance. Augmented reality provides real-time information on the construction site. For example, a person installing electrical cable trays may see plumbing pipes that have yet to be installed. He will then install the tray to avoid bumping the cable tray.
Robotics
Labor shortage remains a constant challenge for construction companies. Construction robotics is an excellent solution to overcome this challenge and achieve faster and error-free construction. Labor intensive tasks like bricklaying, welding, painting, rebar fastening, material loading, etc. can be easily achieved through construction robotics. This technology reduces human effort and reduces the possibility of errors, improves productivity, reduces construction time and guarantees site safety.
These collaborative technologies and smart tools help improve accuracy and efficiency, reduce manual labor, save time and money. The most important aspect of these technologies is that they enable connectivity that is independent of time and location. These technologies help construction companies adapt to the 'new normal' and other unexpected challenges that may affect the construction lifecycle.
