Simulated pre-monitoring value assessment matrix (Walton Bridge)

	Question	Very unlikely or not at all	Not likely	Neutral, i.e. may or may not occur	Likely	Very likely/certain	Comments
	Question	1	2	3	4	5	Comments
SHM engineer	How likely is it that the required accuracy of the proposed measurements can be ascertained?	X					Prediction of failure is difficult (if not impossible).
	How likely is it that the specified system can be designed to be sufficiently robust such that it can be maintained over the life of the monitoring project?				X		Monitoring systems' standards of robustness are arguably improving.
	How likely is it that the appropriate auditing will be conducted by a third party to certify that the gathered data are reliable? (For example, monthly reports that give details of calibrations undertaken and ‘sanity checking’ of collected data.)	X
Structural engineer	How likely is it that relevant values of appropriate threshold values will be assigned in consultation with the asset owner so as to ensure that the owner will act if these values are realised in the field?	X					A meeting was held with representatives of the owner, designer, contractor and researchers present. No suitable quantities to measure were found that would be useful to either the owner or designers.
	How likely is it that the critical monitoring locations on the structure can be determined?	X					Was not possible during the discussions.
	How likely is it that the data be used for validation (or falsification) of structural models which may assist with the design of more efficient future structures for the asset owner?			X			In hindsight may have been a deliverable from the project.
Owner/Asset manager	How likely is it that the necessary actions (or decisions) will be taken if threshold (trigger) values are exceeded/reached?	X					No sensible trigger values could be determined.
	How likely is it that the data to be collected will be able to inform a maintenance regime?	X					No sensible measurand(s) could be determined.
	How likely is it that there will be a secure budget necessary for the intended period of operation of the monitoring project?				X		Willing client so budget probably would have been secure.
Average		1·9					Project unlikely to yield value to the asset owner/manager.
