Sounds like it's a repair and needs an engineer to determine whether or
not it has sustained "substantial structural damage" as defined by the
FEBC below and then follow FEBC 407.3 - 407.3.4

 

SUBSTANTIAL STRUCTURAL DAMAGE. A condition where: 

1.     In any story, the vertical elements of the
lateral-force-resisting system, in any direction and taken as a whole,
have suffered damage such that the lateral load-carrying capacity has
been reduced by more than 20 percent from its pre-damaged condition, or 

2.     The vertical load-carrying components supporting more than 30
percent of the structure's floor or roof area have suffered a reduction
in vertical load-carrying capacity to below 75 percent of the Florida
Building Code, Building required strength levels calculated by either
the strength or allowable stress method. 

 

 

407.3 Damaged buildings. 

Damaged buildings shall be repaired in accordance with this section.

An engineering evaluation and analysis that establishes the structural
adequacy of the damaged building shall be prepared by a Florida -
registered engineer or architect and submitted to the building official.
The evaluation and analysis may assume that all undamaged structural
elements and systems have their original strength and stiffness. 

 

407.3.2.1.1 Extent of repair. 

After the building is repaired the evaluation and analysis shall
demonstrate that the building, once repaired, complies with the wind
provisions of the Florida Building Code, Building . 

 

407.3.3 Below substantial structural damage. 

Repairs to buildings damaged to a level below the substantial structural
damage level as defined in Section 202 shall be allowed to be made with
the materials, methods, and strengths in existence prior to the damage
unless such existing conditions are dangerous as defined in Chapter 2 .
New structural frame members as defined in Chapter 2 shall comply with
Section 407.3.1 . 

 

407.3.4 Other uncovered structural elements.

I agree with Bill.  It could be a repair if it is put back the way it
was. 

If it is being re-configured, then not a repair.  It appears to be a
repair 

with substantial structural damage to me.

I think this is a repair not an alteration.

I vote level 3. It sounds like 100% of the building area requires a roof

which would set the work area at 100%. Also one might argue that egress,

accessibility, & life safety would need to be addressed for 100% of the

building since new interior partitions are being constructed.
