The city government, which already rejected the findings of the PM-appointed panel as a "product of paranoia", had sent a brief report to Prime Minister Manmohan Singh last month, trashing the report.
In the brief report, the government had rejected almost all the findings of the panel and instead accused it of deliberately choosing to adopt a logic of "convenience" in finding corruption in every policy and every tender of the government.
The government is now preparing a detailed report in response to the Shunglu committee findings.
The Prime Minister's Office earlier this month had referred the Shunglu Committee findings on alleged irregularities by certain Delhi government departments to the home ministry for further action.
The city government has already asked officials whose names figure in the Shunglu Committee report to submit their response in writing to the government as soon as possible.
The home ministry is likely to seek reply from Lt Governor Tejendra Khanna and Dikshit and other agencies concerned, held responsible by Shunglu panel for lack of oversight and decisions that led to cost escalation.
The administration of Delhi comes under the control of the home ministry.
