The 2003 ISCARSAH Principles solidified a long-needed philosophical, aspirational framework that ought to govern the assessment of heritage structures relative to seismic concerns and the conception of measures to address their seismic vulnerabilities, giving appropriate deference to heritage value. Annex I of ISO 13822:2010 nudged the high-level guidance in this document toward a practice-oriented azimuth, but more than a decade later, it still appears that significantly more information and guidance needs to be disseminated to practitioners to protect heritage structures from inappropriate or overly conservative assessments and interventions. Approaches to seismic assessment and intervention that are better suited to structures with heritage value than the methodologies and codes that are applicable to new or existing but non-heritage construction do exist, but they are not well-described in the literature and have not, for the most part, been formalized. As a result, they are not widely known and practitioners who may be familiar with them often hesitate to use them due the absence of any detailed methodology for anchoring their assessment and intervention designs; the difficulty of gaining approvals to use alternatives to the regular code from governing jurisdictions; and concerns about liability. As a profession, we need to do better to advance the practice such that there is more widespread familiarity with alternative strategies that are better suited to heritage structures – to enable engineers to incorporate them into their projects when applying the regular code would be ill-advised from a heritage conservation perspective.
