It’s National Engineers Week!
Blog by Emily Pierce, PLS, CFedS
Most engineers would argue that it’s always engineers week, but this week is the “official” week to highlight the stunning array of engineering accomplishments and types of engineering that make our lives easier in every way.
The recent focus on infrastructure has helped bring engineering to the forefront. The tremendous work engineers have done to design and built our bridges, roads, airports is obvious for all to see. And everyone can see what happens when structures outlive their projected lifespan, not maintained properly or not replaced on schedule.

However, many engineers are focused on the infrastructure we don’t see – the underground infrastructure, such as stormwater systems, buried telecom cables, gas and other buried pipelines. It’s a different world below ground where all these systems exist, conflict, age and require maintenance. In the past few years, enormous strides have been made to identify and map underground utilities and structures using new engineering approaches, as well as Geographic Information Systems (GIS).
GIS is a technology that uses maps to visualize data. GIS first appeared as a map created by Dr. John Snow in 1854. He plotted all the cholera outbreak locations in London, along with roads, property boundaries and water lines. His map revealed that cholera outbreaks were clustered around a water pump, challenging the existing notion that cholera was spread through the air. Along with creating one of the first uses of Geographic Information, Dr. Snow also is credited with starting the field of Epidemiology.
MAPPING + COMPUTERS
Mapping and analysis continued to be done on paper until the 1960s. Then, along came Roger. Roger Tomlinson was a British-trained geographer and geologist who worked for the Government of Canada and for an Ottowa-based aerial survey company. He figured out a way to computerize the process. While working on a project to identify the best location for a tree plantation in Kenya, Tomlinson partnered with IBM to find a way to bridge the gap between geographic data and computer services. This initiative was eventually extended to create a national mapping system that created maps of Canada’s commercially-leveraged land used for agriculture, forestry, wildlife and recreation. It was during this project that Tomlinson created the term “Geographic Information Systems” to describe his synthesis of computer mapping with capabilities for overlay, measurement, and digitizing.
SMART CITIES
Today, GIS, ground-penetrating radar and other emerging technologies are helping utilities and cities build a digital map that captures the exact location of utilities. This is a major part of any “Smart City” initiative.
Unfortunately, a disconnect between the real world and the digital world persists, despite all the technology. For example, a growing number of municipalities are using GIS systems to manage the inspection and maintenance of various types of utilities, including stormwater assets. The stormwater manager will use the GIS to schedule inspections, assuming that the data in the GIS is accurate. When the field crew arrives at the scheduled location, they often discover that the data in the GIS simply doesn’t match what they actually see when they arrive. The assets may not be where they are supposed to be, including above-ground assets such as manholes and catch basins. This confusion and uncertainty waste a lot of time which can leading to errors.
Connected RFID
Fortunately, there is now a technological solution that ties the digital world directly to the real world using RFID, the fastest-growing asset ID technology in the world. Engineers at Berntsen International leverage both GIS and RFID to create a simple approach to resolve the digital/reality disconnect. RFID tags, each with its unique ID, are placed on any type of asset. Then the asset ID is connected to its specific record in GIS. A quick scan of the asset will load any applicable forms for the field staff to fill out. This connection means that assets (even underground assets) are correctly identified, and the record is accessible where it counts – in the field for updating and in the office for scheduling.
This simple approach, called InfraMarker Connected RFID, has broad implications for infrastructure asset management. It improves asset locating and identification, speeds inspection and maintenance workflows, reduces errors and supports compliance requirements.
Additionally, Connected RFID provides an important safety mechanism for the management of buried assets. Everyone has seen news stories about gas lines, telecom cables or water mains being accidentally struck during construction. Sometimes these accidents involve injury and/or loss of life, and they almost always result in property damage and loss of service. In 2019, an estimate of the annual societal costs from damages to buried utilities was approximately $30 billion.
If buried assets were marked with RFID, they could be quickly located and identified with a simple RFID scan. Important information about other nearby buried utilities can be easily added to an asset record in GIS, making that information accessible and shareable across utilities.
Thanks to engineers, this technology is available today, making infrastructure asset management more efficient, more useable, and safer.
