The Buddha said to the Devarajas of the Four Directions,"From the countless kalpas in the past to now, Ksitigarbha Bodhisattva has been delivering sentient beings. If He meets those who damage temple properties, he will explain to them the karmic retribution of suffering in hell for millions of kalpas."
I agree with what Carpenter has mentioned. Those who destroy any Holy objects will reap huge negative karma and suffer in hell for many lifetimes. Not only that not meeting the Dharma but also having wrong view continuously until the karma is exhaust.
The team will reap huge merits as they are restoring a place where the Buddha reside and have the realizations to gain Enlightenment.
Buddha said in the Mindfulness Sutra: Who has built well the support [statue], that one will always go from virtue to virtue [always progressing, with more and more happiness, and more and more virtue]. Even for thousands of ten million eons, the virtue can never be wasted or lost. It is saying that one who has built the holy body of Buddha: statue, the holy speech of Buddha: scripture, the holy mind of Buddha: stupa, the temple or shelf for Dharma, and establishes a monastery for the Sangha, gains very extensive merit that is never lost and always increases.
