RE: ASCE Table 1-1 Classification of Buidlings

[Subject Prev][Subject Next][Thread Prev][Thread Next]
We do work primarily for the DoD, including a project a few years ago at Arnold AFB.  It has been our experience that the determination is made by the Corps or Navy but only when questioned.
We recently designed the Command and Control Facility for the 101st Airborne at Ft. Campbell.  We had assumed that the facility would be considered critical to national defense, however, the Corps determined that is was not since the 101st has field capabilities for command & control.  The building was designed as Category II.
We are also working on some security related facilities at one of the Navy submarine bases.  These facilities have been considered critical and are Category IV facilities.
Other determinations used to go to Category IV are facilities that house expensive equipment.  We have designed two helicopter hangars as category IV structures.
What type of facility are you working on?
Hope this helps,

Subject: ASCE Table 1-1 Classification of Buidlings

Does anyone have experience with determining the Category factors in Table 1-1 of ASCE 7-02?  I am trying to determine if a structure that serves an industrial area qualifies as a Category IV type: “buildings and other structures having critical national defense functions.”  The functions at an AF Base may be considered critical, but who determines that?    It looks to me like the nature of occupancy is what needs to be considered.  If the structure is independent of a building and will not cause human injury/loss of life, does it need to be designed in accordance with the categories in this table?

Thanks in advance,
