Accounts on the history and architecture of Assam are scarce. However and important source of information about the Ahom dynasty are the Buranjis; accounts originally in Assamese, written during the Ahom rule (13th-18th Century approximately), under the commission of Ahom kings as a narrative to their rule. Hence, the historic information in these accounts is limited and is covered in myths and legends.
The ASI used to maintain a log of work and condition as site inspection note books, drawings, photographs and estimates of works undertaken on protected structures, on a regular basis. Though this practice may not be regularly maintained, the older logs form an important source of information on the history of conservation of the buildings.
We rely heavily on the first-hand information i.e. the building and the site as the starting reference. Later, we shall be contacting relevant resource persons and other archival material to support our findings. A series of non-intrusive and non-destructive investigations i.e. material studies, condition of foundation and monitoring of cracks and building movements have been proposed and are yet to be undertaken. Specific tests and processes will be mentioned in the relevant sections.
