Alaska 2018 Earthquake Response

CLIENT Alaska Department of Transportation & Public Facilities                      (ADOT&PF) 

Location Anchorage & Mat-Su Valley, AK

On November 30, 2018, southcentral Alaska experienced a 7.1 magnitude earthquake that occurred approximately five miles north of Anchorage. The earthquake caused widespread damage to public and private facilities throughout the area of varying severity.

With a depth of approximately 27 miles, the shaking was felt by a large portion of southcentral Alaska. The ADOT&PF experienced a wide range of damage on the existing road network throughout the region and established two contracts to engage the private sector for support in assessing and repairing the damage.

Shannon & Wilson is involved with both contracts to support the ADOT&PF’s repair efforts. We are currently assisting in evaluation of over 200 sites across the region to observe damage, evaluate the cause, and monitor conditions. The current effort is to triage the sites and determine prioritization of repair efforts. We are currently working on developing recommendations for emergency repairs on several sites and beginning the process of conducting explorations to develop permanent repairs at some of the more severely damaged sites.  

This work is being conducted under a restricted timeline to accommodate the appropriate FHWA and FEMA funding sources. Given the nature of the affected area, the work requires close coordination with team members and the ADOT&PF to ensure that work is being completed in a timely manner
