Athawale said this while addressing the party's 'Nirdhar Melava' at Thane's Central Maidan here.
"The Central and the state governments are delaying the process of construction of the memorial at the Indu Mill land. Now, if the Maharashtra government does not start the work on the memorial by December 5, we will perform the bhoomi-pujan for the project the next day," Athawale said.
The RPI leader alleged that the state government was delaying the process despite the National Textile Corporation (NTC) agreeing to hand over the Indu Mill land for the memorial.
"Now we are left with no other option but to agitate for our demand. The Chief Minister (Prithviraj Chavan) has said that the government would give a befitting reply if there is an agitation, but let him be aware that we are also strong enough," he said.
He added that it would be a world-class memorial.
