Estimating the date the asset was put to use?

Hey all....well i am faced with this wicked situation.

In this Co,the Govt gives grant inorder to do Interior Decorations work. They give the work to various govt contractors. When i went through their Interior Decorations A/c i was only able to see the entries realting to the amounts given to those Govt. Contractors. I am not able to assess what assets were included in these so called 'Interior decoration' inorder to prepare the FA Schedule. Also more importantly i am not able to assess the date on which the asset was put to use. Is 'Management Representation' the only solution to this? Please help!
