Abstract
Major earthquakes can cause extensive damage to buildings and alter both the natural and
built environments. Accurately estimating the financial impact from these events is complex, and
the damage is not always visible to the naked eye. PACT, SLAT, and HAZUS are some of the computer-based tools designed to predict probable damage before an earthquake. However, there are
no identifiable models built for post-earthquake use. This paper focuses on verifying the significance
and usage of variables that specifically need to be considered for the post-earthquake cost estimation
of earthquake damage repair work (CEEDRW). The research was conducted using a questionnaire
survey involving 92 participants who have experience in cost estimating earthquake damage repair
work in New Zealand. The Weighted Average, Relative Importance Index (RII), and Exploratory
Factor Analysis were used to analyse the data. The research verified that eleven major variables that
are significant to the CEEDRW and should be incorporated to cost estimation models. Verified variables can be used to develop a post-earthquake repair cost estimation tool and can be used to improve the pre-earthquake loss prediction tools.
