Ensuring Safety and Efficiency for Denver’s Platte River Bridge
PROJECT OVERVIEW
Denver’s Platte River Bridge is a single-span pedestrian bridge with a unique design that poses distinctive challenges relating to structural movement. To ensure the bridge remains safe and operational, the City and County of Denver embarked on a pioneering project with Stantec, a global engineering firm, to monitor the condition of the bridge. This innovative project used iTwin IoT software from Bentley Systems, along with 16 wireless sensors from Move Solutions, to remotely monitor the bridge and provide continuous access to reliable data and analysis on the health of the structure.
CHALLENGE AND GOALS
The Platte River Bridge’s unconventional design, characterized by a timber plank deck and flexible bearings, contributes to unique movement patterns. This necessitates more frequent structural health assessments than manual inspections can provide.
The project aimed to:
- continuously monitor the bridge movement;
- collect real-time data for improved decision-making;
- prevent costly repairs and potential bridge closures by addressing issues proactively.

SOLUTION IMPLEMENTATION
To comprehensively monitor the bridge’s movement, Move Solutions installed:
- 4 Dynamic Displacement Sensors, for precise dynamic monitoring;
- 3 Tiltmeters, measuring the bridge’s tilt angles;
- 8 Accelerometers, capturing dynamic vibrations;
- 1 Gateway, to transmit data from the sensors.
“Installing sensors from Move Solutions has several benefits: they are wireless, which means we don’t have to string cables from the sensors to our data acquisition system; they are relatively small, so that they are easy to be installed; finally, they are low cost, so we can install more sensors for the same price. “- Alan Jones, Senior Director of Infrastructure IoT at Bentley Systems
“We use epoxy on the side of the sensors and then just stick it in there with a clamp, clamp it in for about 15 minutes, pull the clamps off and it should stay for years.”- John Barone, Principal, Infrastructure Technology Lead at Stantec
PROJECT OUTCOMES
The Move Solutions sensors provided a constant stream of data, enabling daily monitoring of the Platte River Bridge’s behavior. By tracking vibrations and dynamic movement, these sensors have helped improve decision-making and address potential maintenance issues proactively. As a result, the City and County of Denver can now plan rehabilitation projects with greater accuracy. The project serves as a foundation for a larger digital twin of the area, offering expanded opportunities for data integration and analysis. This innovative collaboration demonstrates how technology-driven solutions can enhance the reliability and safety of critical infrastructure, setting an example for cities striving to create resilient and safe urban environments.
“With our solutions we can elaborate information and understand structural health in a way that this wasn’t possible before, giving our clients access to remote, reliable and continuous analysis and data of their infrastructure.”- Ferdinando Frediani, CEO at Move Solutions

Historic Buildings Monitoring
Monitoring a Historic Windmill Undergoing Repair Works
At the beginning of 2022, the SPAB and their Mills Section started a repair project at Kibworth Harcourt Mill, an outstanding historic post mill at Kibworth Harcourt in Leicestershire. Most of its structure dates back to 1711 or earlier and its interior is covered with graffiti of millers who worked there in the past. It is a Grade II listed building and a Scheduled Ancient Monument. Kibworth Mill is the last survivor out of the 211 post mills in Leicestershire, which makes it an important part of local and national milling heritage.

Bridge Monitoring
Tilt and Vibration Monitoring of a Railway Bridge
The bridge located on the Scrivia river, one of the arteries of the homonymous valley, is a structure all about 160 meters long and is divided into 7 spans with lowered arches, in reinforced concrete. Built-in the early 1900s, it served as a road and rail bridge for years. In 1980 the extension of the bridge over the Scrivia (structure in reinforced concrete with slab and beams) was carried out and also a shift of the railway network to its own site, thus splitting the two uses. To monitor the health of the bridge, a wireless sensor network was installed consisting of DECK to monitor displacement and Triaxial Tiltmeter to monitor the inclination of the […]

Construction Site Monitoring
Monitoring a Construction Site to Provide Rail Access to the Depot
As part of the Transport for Wales rail system, a rolling stock depot was built at Taffs Well which required a bridge to connect it to the rail station. Before building the new bridge a sheet pile wall had to be installed in order to retain earth and other filling material during piling activities. The monitoring system provided by Move Solutions through one of their UK supplier, Korec Group, collects real-time data of the sheet pile wall, 24 hours a day, 7 days a week. The aim is to identify any changes in the behaviour and position of the wall so as to avoid structural failure after its removal.
