Four vehicles were overturned, a teleporter was driven into a river, and the wires on four CCTV units were cut on the grounds.
Local groups said they are "ready and waiting" to meet OPW Minister Kevin Boxer Moran.
Speaking on national radio, Minister Moran said he will meet groups in the coming days but no matter what happens "staff come first".
He has committed to meeting groups on the ground over "the next number of days".
He said it "would be wrong to suggest" when a resolution would be found.
He said he needs to work with the groups and that "there has to be compromise and calm."
