The PCN at BHD is fine.
All that is required if it is not up to the full spec is an increase in the frequency of engineering inspections, etc. There are numerous runways, taxiways and aprons in the UK where the PCN does not meet the ACN (Aircraft Classification Number) - this does not prevent large aircraft with high nose wheel point loadings from operating at these sites.
The obstacle environment at BHD is more likely to be of concern to CO than the PCN.
