Shop Drawings / Working Drawings represent a fundamental stage in the execution of engineering projects, as they translate conceptual, architectural, and structural designs into detailed documents that can be directly implemented on-site. These drawings aim to clarify all dimensions, materials, and technical details required to carry out the work without ambiguity. The preparation of shop drawings includes defining actual dimensions, illustrating reinforcement details, electrical and mechanical systems, and service routes, in addition to showing connection points between different elements and any potential clashes. This process also requires full coordination among all disciplines to avoid errors during execution. Shop drawings contribute to improving work quality, reducing waste and delays, and ensuring that contractors and site teams comply with the specified standards and requirements. They also serve as the official reference during execution, auditing, and handover processes.
