Shop drawings provide a visual representation of the project's specifications and are an essential communication tool among various stakeholders.

II. Benefits of Shop Drawings:

  1. Accuracy and Clarity:

    • Shop drawings provide precise dimensions and specifications, ensuring accurate fabrication and installation.
    • They eliminate potential misinterpretations by providing clear visual representations of the intended design.
  2. Coordination and Collaboration:
