Post-Earthquake Utility Infrastructure Recovery

Abstract eng:
Horizontal infrastructure is often overlooked in an earthquake damaged city, because it is out of sight, therefore out of mind. This paper discusses aspects of the challenges in coordinating the repair and rebuild of earthquake damaged horizontal infrastructure within the Christchurch central city rebuild from 2011-present day. In Christchurch, New Zealand, there were no established ways to deal with the massive rebuild efforts required, particularly of the infrastructure. Systems and processes were developed and redeveloped several times post-earthquake. First hand examples from the Stronger Christchurch Infrastructure Rebuild Team (SCIRT) alliance model and Canterbury Earthquake Recovery Authority (CERA), a government organization, are discussed to showcase how effectively the rebuild performed. Lessons learned will be discussed regarding data organization, quality assurance, future proofing and insurance, shared trench layout and Private Utility Company compliance with national laws. This paper is the opinion of an employee that was engaged at both the alliance and the government organization.
