Drawings and specifications are the two sets of documents
given to the constructor that provide technical information
on materials, performance of the constructed facility, and
quality requirements. Drawings are the only documents
given to the constructor that show the design concept, size
and scope of the job, number and size of materials or
items, and how they are assembled into a final project.
Oberlender also underlines that the final product of
design work is a set of contract documents (drawings and specifications) to guide the physical construction of the
project. There are often inconsistencies between the drawings
and specifications. That is why it is critical that drawings
be clear, concise, and uniform. Indeed Gunaydin's
findings indicate that the quality of the drawings and
specifications received from the designer affect the quality
in the design and construction phases, and consequently the
quality of the constructed facility
