Difference between shop drawings and construction drawings

 

One of the most important first steps in successfully completing a construction, engineering, or architecture project is having shop drawings and construction drawings. Although novices in construction frequently use both terms interchangeably, they serve very different purposes. We at Varmine know how important it is to distinguish these crucial documents in order to make a project efficient, precise, and transparent from the beginning to the end.

Construction Drawings vs Shop Drawings

Project managers, contractors, architects, and engineers will avoid delays, errors, and failed project delivery if they know the difference between shop drawings and construction drawings. While both are crucial, the construction of a building requires them to carry out distinct tasks.

What are Construction Drawings or CD Sets?

Official blueprints used in actual building construction are construction plans, also known as CD sets. These are made by architects and engineers, who are the primary people who make legally binding documents that show that stakeholders have agreed. Plans, elevations, sections, and notes about dimensions, materials, and codes are all included.

What are Shop Drawings?

Construction shop drawings are hand-drawn diagrams that are precise and individualized by manufacturers, fabricators, or contractors. The fabrication, assembly, or installation of specific components, such as heating, ventilation, and air conditioning systems, steel frames, or cabinets, is outlined in shop drawings. When it comes to construction, shop drawing plays a crucial role in breaking down general construction blueprints into specific fabrication steps.

Differences Between Construction Drawings and Shop Drawings

Who Should Draw These?

Construction Drawings: Prepared by the project owner-hired architects and engineers. At Rightserve, our skilled design team makes certain that the building construction drawings adhere to project requirements and local regulations.

Shop Drawings: Typically prepared from the construction drawings by suppliers, subcontractors, or fabricators. Rightserve works with certified fabricators to make sure that the project's overall vision is met. prior to the start of construction or bidding during the design phase.

When Are They Prepared?

Construction Drawings: Prior to fabrication or installation and after the construction drawings have been approved.

Shop Drawings: Provide a comprehensive construction plan.

Purpose

Construction Drawings: Give specifics regarding the fabrication and installation of each component.

Shop Drawings:  Legally enforceable with general precision.

Accuracy

Construction Drawings: Based on field measurements and site conditions, extremely precise.

Shop Drawings: Engineers and architects are responsible.

Conclusion

For the success of the project, it is essential to know the difference between shop drawings and construction drawings. Shop drawings precisely carry out the vision, while construction drawings define the layout and ensure legal compliance.
