6 Things You Didn't Know About Shop Drawings

Different types of shop drawings Tejjy Inc.jpg


[edit] Introduction

A drawing or set of drawings that were are produced by the fabricator, contractor, supplier, manufacturer, subcontractor, or consultants is referred to as a shop drawing. For prefabricated components, shop drawings are often necessary. Elevators, structural steel, trusses, pre-cast concrete, windows, appliances, cabinets, air handling equipment, and millwork are some examples. Installation and coordination shop drawings for MEP trades such as sheet metal ducting, piping, plumbing, fire protection, and electrical are also important.

[edit] Types of shop drawings

[edit] Architectural shop drawings

It is not possible to fabricate architectural components without first having architectural shop drawings created. Shop drawings for buildings typically display a greater level of detailed information than architectural construction documents.

[edit] Structural shop drawings

Structural shop drawings are created for structural steel, trusses, reinforced concrete, pre-cast concrete, and other structures. Structural engineers help in creating structural shop drawings which are compatible with the structural requirements of the building.

[edit] MEP shop drawings

Electrical, plumbing, fire protection, and mechanical shop drawings are all included in what are known as MEP shop drawings. These designs aid in the fabrication of these services in accordance with the design and specifications of the structure.

[edit] Facade shop drawings

The structure and shape of any building's facade are depicted in facade shop drawings. Facade shop drawings, which include material specifications and dimensions, aid in the creation of the aesthetic of a building's elevation.

[edit] Conclusion

Shop drawings are an important output of BIM process. shop drawing best practices helps in the building construction process by helping in a precise and fast fabrication process, saving time and labour. Shop drawing services are going to various innovative technologies like AI and robotics, which are making the building construction process much easier and more innovative.

[edit] FAQ

[edit] What are shop drawings used for?

Shop drawings are used for the fabrication and installation of architectural, structural, and MEP services of a building. Shop drawings help in showing a clear picture of how to fabricate various building components and how to build them on the construction site.

[edit] What is the difference between shop drawings and construction drawings?

Shop drawings are the precise drawings that are used for the prefabrication process and installation of building components. While, construction drawings are drawings that are made for the construction process with basic dimensions, and fewer details compared to shop drawings.

[edit] What is a shop drawing submittal?

In construction management, submittals include shop drawings, data on the materials being used, product samples, and data on the finished product. The architect and the engineer are primarily responsible for determining whether or not the correct items will be put on the project, so they are the ones who need to review the submittals.

  1. Customization for Fabrication: Shop drawings are highly customized and tailored to the needs of the specific project. They provide detailed instructions on how various components, such as steel beams, HVAC systems, or millwork, will be fabricated and installed. These drawings go beyond the general plans and specifications.
  2. Coordination Documents: Shop drawings serve as coordination documents that ensure different trades and components work together seamlessly. For example, they help ensure that structural elements align with mechanical and electrical systems without conflicts.
  3. Different from As-Built Drawings: While shop drawings focus on how something will be built or installed, as-built drawings come after construction and show how things were actually constructed. As-builts are used for record-keeping and future reference.
  4. Complexity Varies: The complexity of shop drawings can vary significantly depending on the project and the specific components being detailed. Some shop drawings may be relatively straightforward, while others may require extensive technical knowledge and precision.
  5. Common in Construction and Manufacturing: While shop drawings are often associated with construction, they are also commonly used in manufacturing processes. For instance, in the fabrication of complex machinery or custom-fitted furniture, shop drawings are essential for ensuring accuracy and quality.
  6. Legal and Contractual Significance: Shop drawings can have legal and contractual significance in construction projects. They are typically submitted for review and approval by architects or engineers to ensure they comply with project specifications and design intent. The approval process helps establish responsibilities and accountability among project stakeholders.
