A few of your structures might present deficiencies which cannot be identified by visual inspection, and in these cases you can save money by taking actions before it is too late.
Repair will be cheaper and will cause less interruption to the use of the structure if it is done in time.
Many structures are in much better conditions than you expect! In these cases, monitoring will allow you to increase the safety margins without any intervention.
Monitoring allows a “controlled lifetime extension” of your structure, in a way that you can postpone repair or replacement.
You can use monitoring data to perform "Maintenance on demand“: optimize the maintenance, repair and replacing of your structures based on reliable and objective data.
Monitoring data can be integrated in structural management systems and increase the quality of your decisions by providing reliable information.
Each quality policy requires measurements and feed-back to insure that the objectives are attained.
By providing continuous and quantitative data, a monitoring system helps you in assessing the quality of your structure.
Learning how a structure performs in real or laboratory conditions will help you to design better structures for the future.
This can lead to cheaper, safer and more durable structures with increased reliability and performance.
Having permanent and reliable monitoring data from your structure, you can guarantee the safety of the structure and its users.
When making plans for a long term bridge monitoring system, some factors to be considered are:
Bridges Candidate for Replacement:
Central Conn. Box
Intermediate Conn. Boxes
Typical bridge monitoring layout
Central Measurement Point
Wire or Wireless Connection
SDB StatSTEP 6: Data Acquisition / Mng
The final monitoring aim can often be achieved by indirect monitoring, i.e. by data analysis of results obtained from primary monitored parameters
