Read the passage given below carefully:
In August 2025, the Ministry of Culture released the operational framework for the National Heritage Digitization and Conservation Scheme (NHDCS). Under Section 4 of the guidelines, all Grade-I protected monuments under state jurisdiction must undergo high-resolution 3D laser scanning within 18 months of notification. Conversely, Grade-II heritage structures are explicitly exempted from mandatory 3D laser scanning and are instead required to submit biannual photographic documentation. Furthermore, the framework mandates that central financial assistance of up to 75% is reserved strictly for heritage structures established prior to 1857, whereas structures erected post-1857 are restricted to a maximum co-financing cap of 50% from central funds.
Statement: Under the NHDCS framework of August 2025, Grade-II heritage structures built prior to 1857 must undergo high-resolution 3D laser scanning within 18 months to be eligible for conservation guidelines compliance.
