My answer will be based mainly on my manufacturing experience and some of my construction exposure.
Construction Drawings:
Are set of drawings used to show the relation between different parts of the project. In construction, they will show all axes of columns, overall dimensions and dimensions required to relate/assemble parts together or in location like distance between walls, components and openings. They are produced by consultants.
They can be known as well as execution or installation drawings. They are used on site to build from scratch a building or to check what was built (for inspection). Those drawings need to be reviewed with time and by end of project to produce the As-built drawings if there are some deviation from main intended drawings. Construction drawings have all necessary views and sections to show everything in place and how they are related. They include mechanical drawings, electrical drawings, plumbing, construction and steel structure drawings.
They are also called assembly drawings for manufactured components. They are preliminary assembly designs and detailed assembly designs. Preliminary are used for tenders to show main dimensions and specs required without going into details between parts. Detailed assembly are used for assembly during the installation or assembly process.
All specs of materials, assembly order notes, required torques, ways of assembly and transportation can be shown in the notes. Main BOM (Bill Of Materials) referring to all main components or parts of the project is a crucial part of the installation drawings.
Working Drawings:
They are the very detailed drawings of components and assemblies referred to in the construction drawings. They are produced by contractors or manufacturers. They are mainly fabricated and assembled parts. Those drawings are very detailed in dimensions with finishing, tolerances, and referral to other detailed drawings (if needed). All specs of materials and standards to be followed have to be indicated in the notes and tables.
For manufacturing, there are 2 types of working drawings: Detail drawings and Assembly drawings. Assembly drawings have all components that will be assembled at manufacturer's site or at construction site and referral to bought parts/off-shelf parts as well as manufactured parts, with quantities, specs and standard for each in a detailed table (BOM). Assembly drawing can be 3D exploded and/or 2 to 3 assembled closed views with sections showing all main dimensions relating parts together, with interference fit if present. Other detailed views can be used if components are not clear in their original views. Steps of assembly are mentioned in notes.
Detail drawings are mainly for manufactured parts and they were referred in BOM of assembly drawings. All dimensions are necessary for manufacturing without repetition. Tolerances and surface finish have to be identified for each part and all critical dimensions as possible. Any missing detail can stop production.
RFI (Request For Information) can be asked for any of the above drawings by site supervisors of manufacturer in case of missing information or dimension. No guessing is allowed. In case of doubt, do not scale, ask for what is missing.
