Conservation Laboratory: Of all archaeological activities, those pertaining to conservation are probably the most important. If a timely conservation of antiquities and monuments in not undertaken, the loss will be irretrievable. Therefore, BHDS has begun the process of establishing a conservation laboratory at Patna.
Renovation of Gandhi Camp: BHDS took up the renovation of an important historic building, located in the premises of the A. N. Sinha Institute of Social Studies, Patna. The significance of this building lies in its association with Mahatama Gandhi who stayed here for 68 days during different stretches in 1947. BHDS entrusted the job of renovating building to the Building Construction Limited of the Bihar Government, which executed the job under the technical supervision of BHDS.
