Following the Kaikōura Earthquake and Statistics House investigation, MBIE commissioned a project team to update the seismic assessment procedures for precast concrete floor systems. Their work will update section C5 of the Engineering Assessment Guidelines that apply to Concrete Buildings.
Work on section C5 of the Guidelines has identified corrections that are required for eight equations and their definitions. Eight proposed corrections are presented in the MBIE Consultation: Intention to Correct Equations in Section C5 of the Guidelines for the Seismic Assessment of Existing Buildings. The consultation closes on 26 February 2018. After considering submissions, MBIE expects to finalise the corrections and update the Guidelines in the second half of March 2018.
The Earthquake-prone Building methodology requires the Guidelines to be used for building assessments that councils use to make decisions about whether or not a building is earthquake prone. The corrections can only be used for assessments submitted for this purpose once MBIE updates the Guidelines.
