Abstract

Abstract : Purpose: The purpose of this article is to assist facilities asset managers who are dealing with regulatory environments pertaining to earthquakes and buildings. These professionals can learn a great deal from the successes and short-comings of a case study programme from the Auckland Council Property Department (ACPD), which manages the public facilities portfolio for the largest local administrative region in New Zealand in both population and landmass. Design/methodology/approach: ACPD has initiated its response to New Zealand's earthquake mitigation mandates by identifying buildings most at risk to an earthquake in its large and varied portfolio through the use of a rapid building evaluation programme strategically targeted to vulnerable building types with consequential attributes, including service type, number of occupants, floor area and geographic location. Findings: ACPD was able to rapidly cull down its portfolio of approximately 3, 500 buildings to just over 100 "high-exposure" buildings in urgent need of evaluation, set priorities for future evaluations, estimate needed operational and capital expenditures for long-term planning and provide useful information to more general facilities management decision-making processes. Originality/value: A number of major cities around the world in areas of high seismicity have enacted ordinances mandating seismic retrofitting. However, much of the existing guiding literature regarding earthquake-related portfolio evaluations and costs pertains to specific scenarios involving real or hypothetical earthquakes. This case study, in contrast, details the approach taken by a public portfolio owner responding to legal mandates and attempting to quantify and reduce its life-safety risk exposure across a large portfolio as efficiently as possible using readily available information, a rapid building evaluation programme and best-practice predictive models for consulting and construction work.
