Shop drawings are typically prepared by which of the following?

Shop drawings are detailed and specific illustrations that provide information on how certain elements of a project will be constructed. They are typically prepared by contractors and suppliers because these parties are directly involved in the fabrication and installation processes.

Contractors create shop drawings to illustrate how they intend to construct components of the project in accordance with the design intent provided by the architects or engineers. These drawings serve as a bridge between the conceptual designs and the actual construction, allowing for adjustments and necessary clarifications that ensure that the work adheres to specifications while also considering practical aspects of construction.

Suppliers also play a role in preparing shop drawings, especially when they are providing custom components that need to fit seamlessly into the project. They provide specific information regarding dimensions, materials, and installation methods, which are critical for ensuring proper integration of their products into the overall project.

The involvement of contractors and suppliers in preparing shop drawings is essential to prevent discrepancies during construction, ensure compliance with building codes, and maintain the integrity of the original designs while accommodating any practical modifications needed on-site.
