Firstly scientific clearance of the site along with an archaeologist was carried out where the stone blocks in piles were arranged and methodologically numbered.

The stone blocks with inscriptions were documented separately and an epigraphist to document it and interpret it was involved. This was then followed by the theoretical reconstruction of the entire temple complex with the help of the traditional architect; sthapathy and Aagama expert
