I need to put together a proposal to do a duct bank reliability and condition assessment, whereby a Contractor will do the physical work and engineer observes and writes a report.
The tasks I have thought of:
1. Open manholes and look for obvious damage and rusting of supports. Take pictures.
2. Run a mandrel through each open conduit to verify integrity of each spare, and possibly determine any significant internal damage or deflection.
3. Megger each cable, although I don't think there is historically data to use.
4. Thermal scan any cable which splices in the manholes.
5. Provide updated as left conditions of conduits used and indicate usable and any unusable spares.
6. Check cable insulation types and gather cable manufacturer data on potential damage to cable insulation that has been submersed for 25+ years.
Anything else that would make sense?
Thanks
