The committee, headed by north west Delhi Lok Sabha MP Udit Raj, will also "fix responsibility" of those assigned to ensure Ved Prakash's victory.
AAP candidate Ram Chander defeated Prakash by a massive margin of 24,052 votes.
Prakash won the seat in the 2015 Assembly elections as an AAP candidate. In March this year, he resigned from his Assembly membership and quit AAP to join BJP that fielded him again as its candidate from Bawana.
The committee headed by Udit Raj has been asked to submit its report in next three days, sources in the Delhi BJP said.
The party had deployed a team of 18 leaders including West Delhi MP Parvesh Verma, to work towards the victory of the Bawana candidate.
"The role played by these 18 leaders will also be under the scanner of the committee," sources said.
