requirements set forth in U.B.C. Standard No. 26-9. Test cylinders
of pneumatically placed concrete shall be made in a manner that will

and such cylinders shall be cured and tested as specified above.

111.53. No reinforcing steel or structural framework
of any part of any building or structure shall be covered or concealed

Frame inspection shall be made after the roof,
all framing, fire blocking and bracing are completed and before outside

Final inspection shall be made after the building
or structure is completed and before the issuance of the certificate
of use and occupancy required in Section 121.
|
125.7 Fire Damage. Fire-damaged
buildings, where damage does not exceed 50%, all members becoming
charred, shall be removed and replaced with new members in accordance
with direction of the Building Inspector. Where only smoke damage
occurs, the affected members are to be cleaned and refinished to eliminate
smoke odor. If the damage exceeds 50%, the building is to be demolished
and the lot cleared of all debris.
