Hi Kyle,

 

I wanted to make sure we reiterate the importance of the bullets I sent last week.

 

Please ensure your next submittal has these elements addressed/discussed.

 

  • How to maintain access that meets L & I requirements
  • When concrete/rebar are unknown � the BDM points to AASHTO�s Bridge Evaluation Manual. This document states in section 6A.5.2., unknown steel constructed during or after 1954 shall use fy=40ksi and concrete 3 ksi.
  • The struts being placed interior to the structure � there are several concerns
    • These are not meant for long term dynamic loading � one thought was to have the manufacturer weigh in on the use/longevity of the bracing system
    • How frequently will the team get into the vault to ensure/fix any of the floor props that have fallen? The bridge group was suggesting a weekly check on the vault.
    • How will the floor props be pre-loaded and how will it be designed so they don�t punch through the concrete?

 

In addition, we have been looking through the Environmental Health and Safety Plan but don�t think it covers the requirements of 2.13.6.2 which requires inspection and access plans for enclosed spaces. Let me know your thoughts there.

 

Thank you,

 

-Sonia

Hi Kyle,

 

Please see attached feedback from structures.

 

The larger topics:

  • How to maintain access that meets L & I requirements
  • When concrete/rebar are unknown � the BDM points to AASHTO�s Bridge Evaluation Manual. This document states in section 6A.5.2., unknown steel constructed during or after 1954 shall use fy=40ksi and concrete 3 ksi.
  • The struts being placed interior to the structure � there are several concerns
    • These are not meant for long term dynamic loading � one thought was to have the manufacturer weigh in on the use/longevity of the bracing system
    • How frequently will the team get into the vault to ensure/fix any of the floor props that have fallen? The bridge group was suggesting a weekly check on the vault.
    • How will the floor props be pre-loaded and how will it be designed so they don�t punch through the concrete?

 

I generally have direction/a path to successfully move forward but I am unsure of what that is here. The question that keeps being asked is can they use baker tanks and take the vault offline?

 

An option I heard floating around was � could you build a frame around the vault and place steel plates on top so the load isn�t on the lid of the vault? I think you are too far along for that to be a reasonable option. There was discussion about building a wall on the interior of the vault but that was met with resistance due to accessibility.

 

Thank you,

 

-Sonia
