Architectural working drawings and specifications are crucial parts of contract documents, providing essential information on building design, materials, and workmanship. These detailed drawings guide contractors, ensuring accurate measurements and clear communication for construction. The document outlines the various types of sheets involved in working drawings, emphasizing their importance in the planning and execution of residential projects.

2. ARCHITECTURAL WORKING DRAWING
The architectural working drawings together with the specifications are the
most important parts of the documents constituting the contract. Information
on the designs, locations, and dimensions of the elements of a building is
found on the architectural working drawings while information on the quality of
materials and workmanship is found in the specifications. A good architectural
working drawing gives the contractor the exact information he needs. It should
be clear, simple, and orderly arranged, and accurately drawn so that scaled
measurements will match with dimensions.

3. The finished drawings made by the architect, or draftsman
and used by the contractor are called architectural
working drawings. The architectural working drawings,
together with the specifications and the general conditions,
form the legal contract between the owner and the
contractor. Since the working drawings are a major portion
of the contract documents, they should be very carefully
drawn.
