Reckon you should build a 'tank trap' ditch around all the vunerable bits. I have this horrible image of some poor dehydrated underfed expat worker falling asleep in the 40degree heat whilst levelling the ground in some mammoth Caterpillar machine, or maybe he just can't read the big sign which says STOP
No doubt you'll have a few challenging months ahead, best of luck.
PS. Bad news about the fog again today pity they hadn't delivered that new runway fully capable to you.
