Role in This Project:

K & J has been supporting SoundTransit by providing safety and security certification support services as well as system safety, system security, safety engineering and emergency management consulting services.

2019 – 2022 Planned Activities

K&J has a partnership agreement with Armand Consulting Inc. (ACI) who recently was awarded an on-call safety certification services contract with Sound Transit, Seattle WA. The safety certification process will utilize Sound Transit’s Safety and Security Information Management System (SSIMS) to manage the safety certification process. ACI and K&J leadership will strategically staff the contract to best satisfy the safety certification and technical requirements to manage the initial fifteen (15) capital improvement projects. Safety certification activities start in September 2019.

1:  Safety and Security Certification tasks in support for the Tacoma Trestle Project

Sound Transit replaced the wooden single-track railroad trestle east of Freighthouse Square with a modern, double-track bridge. The new bridge increased passenger and rail capacity along the corridor and improved reliability for Sounder and Amtrak passenger service. The existing wooden trestle would have required structural upgrades within five years to support current and increased rail operations. 

To replace the trestle, crews demolished the current 0.65-mile-long wood structure and constructed a new double-track rail bridge over South 26th and East G streets and crossover tracks. Other improvements included building an expanded passenger platform to accommodate Amtrak passenger trains, making minor street repairs, relocating some utilities, replacing retaining walls at both ends of the bridge and upgrading the railroad signals. 

Certification tasks completed:

  • Threat and Vulnerability Assessment (TVA)
  • Preliminary Hazard Analysis (PHAs)
  • Certifiable Items List (CIL) development
  • Design Criteria Conformance Checklist (DCCC) development
  • Specification / Construction Conformance Checklist (SPCC / CCC) development2
