Title: bldg_repair_DB_FEMA_P58_2nd: DS-LongLeadTime
Post by: rezvan on March 18, 2022, 01:36:50 AM

Dear Adam,

I was wondering if you could clarify the usage of "DS-LongLeadTime" in the csv file containing the component repair information.

Thank you so much,

Pooya Rezvan

Hi Pooya,

Long Lead Time is described in Section 3.9.2 in Volume 1 of FEMA P58:

Quote

Repair time can be significantly affected by long lead times for procurement of critical equipment and components (e.g., HVAC equipment and elevators). Because lead times vary, and are case-specific, they are not explicitly calculated as part of the methodology. If a damage state requires replacement of a component that is associated with a long lead time, this is indicated in the fragility specification and is flagged as part of the assessment results.

Now, in practice, this data is not (yet) used. It is provided to be utilized in the future by more advanced methods for repair time calculation.

I hope this helps.

Adam
