Increasing rates of traffic and the subsequent load strain it causes, in conjunction with general fatigue, can lead to unpredictable bridge failures.
Our bridge monitoring systems accurately detect any structural health issues, enabling maintenance schedules to be planned and the reduction of visual inspections.
Our bridge monitoring solutions are varied and tailored to individual projects. We offer full bridge monitoring schemes or specific bridge component monitoring.
Our expert monitoring team, combined with our structural engineers can also implement any remedial work that may be required on a bridge.
Offering the complete solution, we can mitigate any risks by integrating our large range of propping and jacking equipment and controlling any lifting with our computer controlled hydraulic jacks and monitoring systems. The perfect solution to keep your bridge safe whilst any remedial work is undertaken.
Below are some of our more common bridge component monitoring solutions.
Aging, nearby works or any repair works on a bridge, can cause a bridge to move. Typically, this is by millimetres but can be more severe and over time, could cause failure of the bridge.
Our solutions are able to monitor any movement either continuously, using our total station and prisms or manually using our 3D scanning equipment.
By placing displacement sensors underneath the deck, we can provide a strong assessment of the structural integrity of a bridge at different loads.
The insight gathered from this long or short term monitoring can provide assurance that a bridge remains safe under load or alternatively, requires a maintenance and repair plan putting in place.
Our experts also have extensive experience monitoring load throughout bridge jacking and de-jacking operations ensuring optimum safety at all times.
Movement or degradation in the abutments or piers of a bridge, can have an impact on the overall structural health of the bridge. The monitoring of these key components of the bridge, is therefore often performed as part of a full bridge monitoring scheme.
Soft ground conditions below bridges present settlement and stability issues for abutments. Conversely, well compacted, heavy material around the base of an abutment can cause rotation, which can lead to full expansion joint closure or even bowing of the deck in more serious cases.
Crack identification is one of the most important aspects of structural health monitoring. Cracks will occur in most structures and are often the first signs of more serious defects.
Using our monitoring solutions, we can record and observe the changes in crack behaviour in real-time, providing much more accurate and detailed insight than visual inspections. This ensures that potential structural failures are detected at an early stage, helping to ensure that our bridges remain safe and in good structural health.
Environmental conditions, grit or residues from the road, aging and fatigue, are all factors that can cause bearings to cease which can be catastrophic for the bridge deck and the pier.
By using our displacement sensors to monitor the movement of the bearings over time, any maintenance requirements can be planned in, ensuring the bridge remains safe and enabling any costs to be planned in. We also have solutions to measure the temperature of the concrete in order to monitor any thermal expansion and contraction of the bridge.
Residues and grit from the road can cause corrosion and blockages on the expansion joints.This can affect the expansion properties of the bridge, which in turn can cause deck seizure.
Change of movement outside the normal expansion of the bridge, could also identify that the expansion joints need some general maintenance.
Implementing structural monitoring can highlight the need to maintain or replace any steel expansion joints before these issues occur.
