Executive engineer Ravindra Kumar, assistant engineer Bharat Bhusan Nagpal and junior engineer Dev Raj were suspended during an inspection of the construction site.
The Minister's move comes after he received several complaints from local residents about the engineers allegedly using poor quality raw material to build the community centre in Harijan Basti situated in Khaira village.
Rai, who also holds the charge of Flood and Irrigation Department, has formed a probe committee to be headed by Special Commissioner (Development).
"As per preliminary investigation, Rai found assistant engineer, junior engineer and zonal executive engineer guilty. Thereafter, he suspended all the three officials," a senior government official said.
The official said that a sample of construction material was picked up from the site and sent to a laboratory for examination.
"All three officials will remain suspended till the committee's report comes. In the committee, MLAs - Kailash Gehlot and Gulab Singh - will also be members," the official added.
