In building, a submittal is a document or a sample issued by a contractor to the architect or engineer to review and approve the document or sample. Some of the details listed in it are materials, equipment, drawings, etc. Submittals provide for what can be termed as the compliance of what is clocked on the job with specifications of the project. According to Houseura, such reviews aid in the preservation of quality and compliance without incurring the errors before the installation starts.
