Technologies that will change the face of construction.

Construction projects are renowned for running over time and over budget but it’s no secret that construction can be very slow when it comes to change. A general need for change has emerged as a result of the serious productivity problems that are noticed in big markets like the United Kingdom.

Other industries such as manufacturing have turned around costly productivity problems by bringing in new technology. I’ve compiled a list of the most exciting trends to watch out for in the next 2-3 years in this fast-moving field for construction firms wanting to actively embrace technology in the quest for improved productivity, safety and efficiency.

The Internet of Things (IoT)

IoT is the connection via the internet of devices and everyday objects. On a construction site, in relation to equipment monitoring and repair, IoT can track assets and their movements around sites. Sensors can enable machinery to transmit information about their status and any need for service or repairs. For equipment used by workers, hours worked can be logged automatically, limits can be monitored to prevent worker fatigue and possible accidents.

To increase energy efficiency, machines can send back information on idling time (which uses fuel) so that on and off periods can be adjusted. Sites can send back information on the amount of electrical power they use, so that after-hours lighting can be adjusted for energy savings.

Computer models can be used to direct real-life construction and thereafter be updated by sensors in the constructed buildings. Sending back information on the way materials are affected over time and by changing climates.

Smart devices and wearable technology, as well as sensors and on-site cameras can inform construction management software and give a much clearer picture of building progress and real-time status reporting.

This integration not only affects the flow of a project, but also provides vital data that can be examined after handover to become a part of operational management. Sensors that provide information on environmental conditions and structural performance are of importance in this area.

AI and Machine Learning

The use of specialised software to simulate human thinking and analysis and artificially self-learn.

As the internet of things continues to pull more and more information, construction firms will need tools to manage all this data. This is where machine learning is becoming increasingly crucial. Systems that aggregate and organise data from the connected developments are going to be vital as construction firms become more reliant on real-time information for efficient project management.

AI and machine learning in construction is going to become a must for collating and analysing multiple streams of data from an integrated digital workflow. Properly trained AI can categorise data faster than a human operator, cutting the time needed to get the clearest picture of issues on an active development.

Machine learning is already creating opportunities for new uses of technology, such as the way our technology partners are aggregating visual information from on-site cameras and uses artificial intelligence to tag potential hazards and safety violations. This technology is just the tip of the iceberg, and we expect to see more innovative applications of machine learning going into 2021 -2023.

Predictive Analytics

Along with machine learning, systems that not only feed information to the head office but can also look ahead and provide insight into safety concerns, scheduling, or budget outlooks are going to see increased development and innovation. Predictive analytics combines techniques like data mining, statistics, modelling, machine learning and artificial intelligence to analyse data and make future predictions. The purpose of predictive analytics is to create a new approach to problem solving using data, predicting patterns in our workflow and highlighting innovative solutions. The predictive systems can anticipate problems as well as opportunities and give project managers insight into critical decisions.

Now this is still new technology? But we know it’s going to see some amazing developments as our clients begin to explore its potential. 

Virtual Reality / Augmented Reality

Virtual Reality, no longer the sole province of video games, is another technology that is on the rise and it’s called Augmented Reality. The tools that bring VR and AR to leading developments are becoming more and more ubiquitous (and more user-friendly) and as this technology becomes more integrated in the digital workflow, the possibilities that open to the construction sector seems limitless. Virtual Reality in construction allows real-time comparison of 3D models to physical spaces; overlay of location and position data (wireframes) during installation; virtual walk through's with project stakeholders… these are just the beginning.

Our studies have found that VR and AR tools are already reducing rework and increasing safety. One of our partners has designed a helmet, that offers users improved situational awareness, calling attention to environmental factors, such as temperature differentials and unsafe conditions. It can also be used to increase the precision of complex installations and is creating a whole new world of possibilities for collaboration between innovative designers and builders.

Autonomous Equipment

While VR is enhancing the productivity of humans, automation and robotics is providing a path to greater safety and efficiency, including the use of drones in construction. Sending a drone to inspect a development saves time and keeps the technician on the ground instead of climbing scaffolds and navigating the potential hazards of a working site. There are current available drones that can generate a 3D model of a site that allows automatic calculation of area, volume of earth to be moved, and other information that once required several human hours to accomplish.

Automated rovers will also be providing job site status information, monitoring sites autonomously, guided by AI in the home office and feeding data back to the predictive analytics systems. We’re also seeing automated equipment being developed in the form of driver-less earth movers and dump-trucks in mining and road-building applications.

Next Generation Tools

There are always going to be better and more powerful tools. This has been the case for thousands of years. But the next generation of tools are different. These devices and robots come with their own software, that's a different story. The software comes with updates and eventually machine learning. This means the average low-level worker is potentially replaceable in 20 years. But we must keep in mind that emerging technology takes the form of software and hardware. A great example of extraordinary hardware technology undoubtedly is exoskeletons.

Exoskeletons are devices that allow workers to get more efficiency out of all movements while also being able to lift, carry, and pull more. They can reduce daily strain and provide an additional element of safety on site. However, these robots are still far too expensive for the benefit they provide now. They're much more likely to be seen after 10 or more years when the software is flawless, batteries are improved, and the price drops.

Green Construction

Last but certainly not least, green construction! The amelioration of the construction process in conjunction with the productivity increase allows for a ‘greener’ construction process to arise. The goal, in this case, is the establishment of sustainable building as the prevailing construction procedure. It goes without saying that, it requires tons of work and effort before this ambition comes to life on a greater scale.

In short, green construction can have some great benefits not only for our industry but for our environment and everyday lives. More specifically, it can help in reducing energy waste, reducing the reliance on the grid for electricity, increasing productivity and establishing higher sustainability living and aesthetic standards. There still are many who are reluctant toward green construction due to the slightly higher cost during the construction process. Nonetheless, this is not correct if we consider the full living cycle of the building. A sustainable building structure can be much more beneficial in the long run. That is why green building is an option that must be thoroughly explored now.

What drives these construction technology innovations?

We wanted to take a moment and talk about what is driving the adoption of these innovations in the construction industry. It should go without saying that competition is key here. As many firms are finding it difficult to compete on price, Thoth London are finding ways to reduce costs and inefficiencies. Also, the UK’s “brain drain” as seasoned professionals begin to retire, and significant amounts of institutional knowledge is being lost with their departure.

Technology is giving us a way to capture much of that experience and bridge the gap in knowledge, especially as the next generation of “digital natives” brings a new enthusiasm for technology to the Construction site.

Finally, connected digital workflows also redefine collaboration, allowing stakeholders and owners up-to-the-minute information on project status and decisions. What we’re seeing is a blending of old and new, as we move into the future as an industry.
