Mr Wike gave the order in Abuja on Tuesday when he visited the area officially known as ‘Road N12’ in Mabushi District of the FCT.
FCTA impounded 69 vehicles for various offences as part of its continued efforts to make Abuja city safe and clean.
The suspect, Yusuf Ibrahim, denied the allegation, claiming they had not sold land to anyone in the area.
“We got information that some owners of the revoked lands are moving to the site in violation of the order,” said Mr Galadima.
“The committee will be looking out for structures that visually may look stable but not, and recommend an integrity test,” Mr Galadima said.
After some cleanup of operations at Asokoro and Maitama, the director said the department would sustain the cleanup exercise.
Mustapha Suleiman, one of the occupants of the buildings, appealed for the meeting to be rescheduled to Friday and it was granted.
The building, located on Lagos street, collapsed on Wednesday at about 11:50 p.m., killing two and injuring many.
He lamented that individuals acquire properties and lands from the natives and develop them without approval from the FCTA.
According to him, the operation is an ongoing exercise to clean up Abuja city by removing all illegal structures wherever they exist.
