What drawings and documents does a chemical engineering construction project design institute need to provide to the owner?

This depends on the specific project; generally, there are: design specifications and preliminary design； Material balance sheet, process flow diagram ； General layout plan ； Special sections on safety design, fire protection design, environmental protection design, occupational health, etc. (I heard that safety and occupational health have been combined this year.) Pipe design specifications, pipe instrumentation diagrams, pipe numbering tables, pipe grade tables, pipe layout plans ； Empty view, pipe material table ； Equipment list, equipment layout plan ； Engineering drawings for custom equipment, equipment manufacturing blueprints, process data sheets for complete sets of equipment, technical specifications for the procurement of complete sets of equipment ； Pump data sheet, instrument data sheet ； Public utilities (including underground pipeline networks and construction specifications); regulations for insulation and cooling of equipment; specifications for anti-corrosion treatment; painting ； Electrical equipment design, technical specifications for the procurement of electrical equipment, electrical cable layout diagrams. Control systems, etc. I am not a professional; this is for reference only.

The level and depth of the drawings provided at each stage vary, as specified in the standards. The feasibility study phase involves drawings that meet the requirements of feasibility studies; the preliminary design phase provides drawings that satisfy the needs of preliminary design; the detailed design phase delivers various professional drawings required for construction; and the completion inspection phase provides a complete set of as-built drawings.

The simplest answer: it depends on what the owner needs!

Various processes, electrical systems, instrumentation, fire protection, equipment, preliminary design, and so much more!
