Fundamentals of IoT for Construction – Greater interconnectivity defines success
Probably the best definition of the Internet of Things (IoT) appears in a Forbes magazine article written by the futurist Jacob Morgan. According to Morgan, the IoT refers to the concept of “basically connecting any device with an on and off switch to the Internet (and/or to each other).”
This includes everything from smartphones, coffee makers, washing machines, lamps, wearable devices and almost anything else. It also applies to components of machines, for example a jet engine of an airplane or the drill of an oil rig. Again, all of these examples have an on and off switch.
Which begs the question: why? Why would we want a thing, such as a coffee maker, connected to the Internet? Easy, to get it brewing so when one comes downstairs after showering and getting dressed there’s a pot of freshly-made coffee waiting and/or after leaving for the day to turn it off if checking confirms that it was absentmindedly left on.
A 2013 Global Standards Initiative on Internet of Things defines the IoT as “a global infrastructure for the information society, enabling advanced services by interconnecting (physical and virtual) things based on existing and evolving interoperable information and communication technologies” and for these purposes a “thing” is “an object of the physical world (physical things) or the information world (virtual things), which is capable of being identified and integrated into communication networks.”
The Global Standards Initiative further stated that “the IoT allows objects to be sensed or controlled remotely across existing network infrastructure, creating opportunities for more direct integration of the physical world into computer-based systems, and resulting in improved efficiency, accuracy and economic benefit in addition to reduced human intervention. When IoT is augmented with sensors and actuators, the technology becomes an instance of the more general class of cyber-physical systems, which also encompasses technologies such as smart grids, virtual power plants, smart homes, intelligent transportation and smart cities. Each thing is uniquely identifiable through its embedded computing system but is able to interoperate within the existing Internet infrastructure. Experts estimate that the IoT will consist of about 30 billion objects by 2020.”
Construction Industry Is Out Front
When examined, the technologies behind the Internet of Things have existed for many years in the construction market. Features like remote access, office-to-field data exchange, cloud computing and data storage are not new to the construction industry. Granted, not all construction contractors have invested in these new technologies, but it has been available for some time. Whereas in consumer markets, these technologies are still new and revolutionary. In the consumer sectors, new connected ‘things’ are just coming to market. In the construction realm these connected devices and real-time communication already exist, and now it is more about contractors accepting and investing in the technologies. The technology developers in the construction market are now focusing on creating easier, reliable access to the abundance of data.
Think about it, for consumers, it is all about convenience rather than criticality. If, for instance, a smartphone breaks for a consumer, it is not the end of the world (well, for some people it is). But for a construction contractor, a smartphone, tablet, or laptop failure can raise concerns about the security, data integrity, and response times, which are absolutely critical.
“Interconnected smart technology is central to how we engineer our solutions and their functionality in the hands of our customers,” said Ivan Di Federico, executive vice president and chief strategy officer for Topcon Positioning Systems. “The opportunities are seemingly limitless. The power of IoT provides comprehensive planning, process control, workflow monitoring and extensive reporting that will bring our customers the full advantages of connectivity.”
IoT Platform
What is referred to as the “IoT Platform” is the operating world in which the construction market has been evolving. The IoT Platform is meant to provide construction equipment manufacturers and the end-user contractors with analytics and reports about various aspects of their tasks and assets, in order to enhance the decision-making process and obtain the best possible management of resources, fleets and personnel.
In the construction field, the key is sensors. Sensors make it possible to capture all the information needed to improve decisions with real-time data about the work site and the workforce.
Equipping each piece of equipment with the capability of sending and receiving data allows the platform to reproduce a digital detailed representation of the product itself. That is called a digital twin.
“Thanks to the digital twins of our products, activities like monitoring, diagnosis, and repair can be completed remotely,” Di Federico said. “What this means is we can have experts based anywhere in the world able to provide monitoring, troubleshooting, and/or repairs without needing to be physically there at the worksite or contractor’s location. This would result in tremendous savings of time and travel expenses. Moreover, there can be direct collaboration between on-site personnel and equipment operators and our experts.”
Data is Key
Smart, connected construction equipment can allow tracking of how they are being used. Through the accumulation of historical data, the IoT platform can build patterns of information to better understand customer-contractors’ necessities, the environment in which they operate, and provide advanced solutions to fit their needs. Indeed, data collected from smart, connected products and systems provide detailed information on how the products’ features are used, which are most useful, and which are ignored.
The collected data, which is called Big Data, provides options for different types of analysis:
- Descriptive — to retrieve a detailed report of current conditions and understand what happened in a specific working environment;
- Predictive — to provide a reliable prediction about product performances and forestall the occurrence of potential malfunctioning or damage;
- Prescriptive — to know how to optimize and automate the process and the workflow via realtime project maps and plans which feed the machines.
The platform provides numerous and detailed information that can be selected according to the need at the time. This enables making effective and profitable choices. It is possible to retrieve virtually any useful information, from fuel consumption to equipment productivity, from maintenance services to, in the near future, prognostics. In addition, most of the functionalities are completely customizable, for meeting specific contractor needs (e.g. dashboard layout, alarms and notifications, CAN-Bus parameters, units of measurement, language).
For the contractor owners and managers, analytics is possible to compare usage patterns in order to improve services, increase productivity, ensure better quality, and create more accurate pricing and bidding strategies.
The ultimate benefits of Big Data is cost reductions and deeper insights as to what customers need.
“Interconnected smart technology is both central to how we engineer our solutions and produce their functionality for our customers,” said Di Federico. “The challenges, as with most innovation, have mostly to do with adoption. Once construction contractors have an opportunity to see first-hand how the solutions we provide make them more efficient, the concept of IoT makes perfect sense. Greater productivity means undeniable higher profits for their businesses, and assists them in meeting what we at Topcon call The Intersection of Infrastructure and Technology. It is the meeting point where construction productivity is improved by applying intelligent positioning technology, and clearly IoT is part of this bigger picture.”
For Topcon and other technology companies in its niche, providing connected solutions to the construction market enables contractors to have comprehensive monitoring of conditions, operations and the work site through sensors and data. This means monitoring knows no boundaries. Assets can be monitored from everywhere, wherever the contractor happens to physically be. It enables real-time communication and task management with machines and crews on the work site. Additionally, the entire fleet of machines working at the site can be connected.
“We call it ‘descriptive, predictive and prescriptive’ analytics,” Di Federico said. “The result for customers is higher productivity, less downtime and waste, and ultimately more profitability, combined with less stress.
“We absolutely design our solutions with IoT top of mind, such as our Topcon Tierra remote asset management system that provides total visibility and control, including diagnostics and maintenance for reducing costs and improving performance.
“Our MAGNET software solutions suite, provides real-time connected support for hardware as well as integration with our Sitelink3D service for instant data transfer and connectivity into active project sites. Additionally, Sitelink3D allows customers to plan, schedule, assign tasks and get reports, all in real time. When practically any new product or system is designed, integration with these solutions is standard and expected procedure.”
The IoT is here to stay. It is the future, and for many it is the present. In the construction market, the success of technology that enables construction contractors to bid projects more accurately based on their own historic production data and get their jobs completed faster, more accurately, and more efficiently using intelligent interconnected technology, has raised customer expectations.
“For construction contractors and OEMs today the tremendous benefits of IoT enhances the decision-making process for obtaining the best possible management of resources, fleets and personnel,” said Di Federico.
