To prepare project specifications, the architect requires documents that inform about site conditions, building construction, and interior finishes:

Geotechnical report provides soil conditions, foundation recommendations, and site constraints.

Building sections provide detailed information on assemblies, materials, and vertical relationships.

Room finish schedule identifies finishes, materials, and related specifications for interior spaces.

Legal surveys, traffic management plans, and door schedules are important for planning and design coordination but less directly informative for writing specifications.
