Reasons for Repair:
 This
sixty-two year old reinforced concrete structure has experienced
significant concrete spalling on both the underside of the thin
shell concrete roof and the exterior arches due to the corrosive
marine environment that exists at this hangar which is located about
400 feet from San Diego Harbor.
The most significant spalling occurred in the year 2000 causing
much concern by the Navy since some spalls fell from a height of
nearly 80 feet onto the hangar bay floor which was occupied by large
numbers of Navy personnel and costly helicopters. Some of the concrete
spalls were from previously repaired spalls, and they weighed as
much as five pounds.
Obviously, the Navy became very concerned with these concrete spalls
falling on the hangar bay floor, thus, all personnel and equipment
were consequently evacuated from the hangar bays to the adjacent
apron areas. Hence, the maintenance functions of Hangar Building
340 were compromised and the efficiency of the operation decreased,
especially during the winter months.
