Overview

Fiber Optic Sensing Systems (FOS) are rapidly transforming how infrastructure health is monitored, offering real-time, high-resolution measurements of strain, temperature, displacement, and vibration. By leveraging the properties of light within fiber optic cables, these systems provide continuous, long-range data acquisition without the need for electrical power at the sensing points. They are ideal for monitoring large-scale assets such as bridges, tunnels, dams, pipelines, buildings, and railways.

These systems offer significant advantages over traditional sensor types, particularly in environments prone to electromagnetic interference or extreme weather. For B2B clients across North America, FOS offers a scalable, low-maintenance, and future-ready solution for structural and geotechnical monitoring.

Enviro Structural Monitoring supports the integration of Fiber Optic Sensing Systems into new and legacy infrastructure. We help clients future-proof their monitoring capabilities through robust hardware, software platforms, and expert services tailored to high-performance, long-term operations.

Industries We Serve

A cityscape featuring a cluster of modern skyscrapers under construction, with multiple tall cranes surrounding them. The scene is set against a sepia-toned sky, giving it a vintage look. Elevated highways crisscross in the foreground, adding an urban complexity to the composition.

Civil Engineering and Construction

A city street at dusk features tall buildings lining both sides, with cars driving along the wet road reflecting the streetlights. The sky is overcast, creating a moody atmosphere in the urban setting.

Transportation & Railways

An offshore oil rig stands prominently in the ocean, featuring a red and yellow structure with cranes and equipment. The clear blue sky and distant shoreline provide a serene backdrop.

Energy & Utilities

A scenic landscape features tall power lines stretching across a grassy field at sunset, with a vibrant sky of blues and oranges creating a serene backdrop.

Mining & Tunneling

A lush forest scene with tall, slender trees reaching upward, surrounded by dense green foliage. A narrow, winding path cuts through the undergrowth, leading deeper into the tranquil woods.

Defense & Homeland Security

A bright yellow forklift is positioned in a spacious warehouse, maneuvering a large pallet. The industrial setting features high ceilings, metal beams, and stacks of boxes and materials, creating a busy and organized environment.

Case Studies

A bridge under construction spans a river, supported by multiple tall cranes and cables. The structure features several vertical towers and a partially completed roadway. Workers and construction equipment are visible on the bridge, with a backdrop of lush green trees and distant hills under a partly cloudy sky.

U.S.: Earthquake Monitoring on California Bridge Network

A leading DOT in California deployed FOS across a network of bridges in seismic zones. The system successfully captured microstrain data during minor seismic events, enabling the department to create a prioritized inspection schedule and prevent unnecessary closures.

Canada: Smart Tunnel Monitoring in Toronto

In collaboration with a Canadian engineering firm, fiber optic sensors were embedded into concrete segments of a newly constructed underground tunnel in Toronto. The system continuously tracks load-induced stress and thermal fluctuations, reducing the need for invasive inspections while ensuring tunnel stability during operation.
