6.2 Maintenance
A correctly installed and certified MegaRail VRS is maintenance free for the
period of its design life. A visual inspection regime is recommended to check
for impact damage. Where this is identified, repairs must be carried out.
The visual inspection should also look at the ground conditions as erosion,
slippage or ponding water can all affect the viability of a VRS and therefore
must be maintained in good order.
6.3 Repair
When repairing MegaRail VRS only components with visual residual plastic
deformation need to be replaced. If the deformation is minor damage to a
beam and is localised, then no replacement is necessary other than for
aesthetic reasons.
Minor damage could be small scratches and indentations which should be
treated with a zinc rich paint. Substantially damaged beams must be
replaced as must any bent posts. The bolt holes in adjacent beams should
be checked for splitting or distortion and if any are identified those beams
should also be replaced.
The repaired installation should be checked for compliance with the system
specification and an inspection certificate produced. When replacing
damaged components all fasteners that are removed must be replaced with
new. Care should be taken to ensure ground conditions are suitable to
support the replacement posts. Re-compaction of the ground may be
required or driven posts may have to be replaced with concrete foundations.
If concrete foundations were not designed to be survivable then they should
be inspected to ensure no cracking or movement has occurred. If there is
evidence of either, then the foundation should be replaced. In all probability
it will be necessary and most practical in these circumstances to install a
larger foundation thereby removing all the disturbed ground.
Damaged components should be disposed of in an environmentally
responsible way.
6.4 Innovation
SAFEROAD lead the VRS market in innovation and continually strive for
improvement, so with the passing of time existing installations may not be as
per the current drawings, so manuals and drawings from the time of
installation should be kept on file.
