5.4 Access for Inspection and Maintenance
All structures of Osmangazi Bridge are accesible for
inspection, maintenance and for replacement
purposes. The most suitable equipment to provide
safe, efficient and effective access were chosen and
provided during the design phase.
For all equipment installed at high level, facilities for
maintenance were designed either as permanent
working platforms or as flexible mobile elevating
platform.
5.3 Reporting
After each major inspection, inspection reports shall
be prepared which include detailed descriptions of
any damage or deteriorations with pictures. Hard
copies and soft copies of inspection reports are
recorded. Those records will be used in planning and
execution of future maintenance and repair works.
The tower internal area, tower top and saddle
enclosure areas, tower external faces, anchorages and
caisson interiors, expansion joint areas, main cable
and hangers are all designed to have permanent
access as described below.
The walkways of the bridge deck serve as a dedicated
access lane, to be used by maintenance vehicles for
reaching the designated maintenance location in a
fast and efficient manner without disrupting normal
traffic.
After maintenance, detailed reports shall be prepared
which include description of the maintenance, and
maintenance costs spent. These will help and be used
in planning/evaluation of alternative maintenance
strategies for high cost future maintenance
operations and prediciting the remaining service life
of components.
