What is a Shop Drawing in Construction

In construction, many drawing sets are needed before building starts. These sets help everyone involved from the start to the end of the project. Architects create construction drawings that show the design. Contractors make shop drawings that show how things will be built.

These 2D documents are key for building big and complex structures. All kinds of architectural and construction drawings are vital for any project.

Introduction to Shop Drawings

Definition and Purpose

Shop drawings are key in the construction world. They are detailed drawings made by contractors, suppliers, or manufacturers. These drawings give more information than regular construction documents.

They are vital for making sure building parts fit together right. This includes things like elevators, steel, and windows. They help make sure everything is made and installed correctly.

The main goal of shop drawings is to share the design, how to make it, and how to install it. They help everyone involved in a project work together. This way, the project can be done well.

Good teamwork is key to a successful project. Shop drawings help make sure everything is right before it’s installed. This is especially important in remodeling, where things can change.

Building information models (BIM) are also making shop drawings more important. BIM helps everyone work together better. This makes the construction process more efficient.

Differences Between Shop Drawings and Construction Drawings

In the construction world, both shop drawings and construction drawings are key. But they have different jobs. Construction drawings are made by architects or engineers early on, before building starts. They show the exact details of the building parts, helping make decisions and guiding contractors.

Shop drawings, however, are made by contractors and others after a deal is made. They make sure the design is followed correctly, considering the site and materials. Unlike construction drawings, shop drawings are precise, with correct sizes and how things fit together.

Responsibilities and Timelines

Construction drawings are made early, during planning. They are the base of the project, making sure everyone knows what’s needed. Shop drawings, though, come later, after the contract is signed. They focus on the details needed for making and putting in place building parts.

Construction Drawings

  • Created by architects or engineers during the design phase
  • Contain detailed specifications and serve as bid drawings
  • May contain errors or ambiguities

Shop Drawings

  • Created by contractors, subcontractors, manufacturers, or suppliers after the construction contract is signed
  • Interpret design intent and provide fabrication and installation details
  • Provide accurate dimensions and assembly details from professional engineers

Purpose and Details of Construction Drawings

Construction drawings are key in the building world. They are detailed pictures made by architects before a project starts. These drawings show what the final building will look like.

They cover important details like how the building will be used, its look, size, and materials. You’ll find plans for the building’s layout, electrical systems, and more. They also show how different parts of the building fit together.

These drawings help make sure the building is built right and on time. They act like a blueprint, giving exact measurements and how things should be put together. They also help spot any mistakes early on, saving money and time.

But they do more than just help with building. They are also needed to get permits and approvals. They make it easier to do repairs or changes later on. And they keep a record of the building’s final state for future reference.

What is a Shop Drawing in Construction

In construction, shop drawings are key. They fill the gap between design and actual build. These detailed drawings show how to make and put together building parts like beams and equipment.

Shop drawings make sure everything is built right. They follow all the rules and codes. They are also called prefabrication drawings. They give a detailed look at how things should be made.

These drawings focus on one product or installation. They don’t include details about other products unless they need to work together. This helps sub-contractors know exactly what to do before starting.

Information Included in Shop Drawings

Shop drawings are vital in construction. They provide detailed information for making and assembling building parts. Contractors, subcontractors, and suppliers create these drawings. They outline how to follow the design plan in the contract.

Fabrication and Installation Details

These drawings include lots of information. They have material tags, clearance needs, and how things fit together. They guide how to make and install parts on-site.

Shop drawings show how the contractor will follow the design plan. This is important, as the AIA A201–2017 and EJCDC C-700–2018 contracts state. The design team checks and approves these drawings before making anything.

Design drawings show the big picture. But shop drawings get into the small details. They cover things like size changes, updates, and how to install.

This detail is key for a project to go smoothly. It helps the team solve problems before they start on-site.

Review and Approval Process

The shop drawing review and approval process is key in construction. It makes sure the parts made match the design. Architects, engineers, and contractors work together to check and okay the drawings before making them.

First, architects and engineers look over the drawings and give feedback. Then, the supplier or contractor makes changes based on this. This back-and-forth makes sure the drawings meet the contract and speeds up the process.

If the designer and fabricator use the same CAD software, things go smoother. They can talk and work together better. This teamwork is what leads to successful installations.

Many companies use junior staff for this task or bring in outside experts. This helps keep costs down and avoids extra expenses. It’s important to catch any issues early to avoid problems later.

Engineers are crucial in this process. They make sure contractors do their job right, like reviewing drawings. Contractors must tell architects in writing if there are any problems. This keeps everything clear and fair in the shop drawing review and approval process.

Coordination and Clash Detection

In construction, getting shop drawings right is key to success. Old ways of doing things can be slow and lead to mistakes. Now, more Architecture, Engineering, and Construction (AEC) firms are using Building Information Modeling (BIM).

BIM makes coordination better and finds fewer problems in the field. It helps spot clashes in meetings, automatically, and in the field. This way, all parts of a building can work together smoothly, saving space and making things easier to build.

Coordination drawings show how different systems fit together in 3D. They change often as problems are found and fixed. This makes sure all parts of a project work well together.

Using BIM, construction teams can make the coordination and clash detection process better. This means fewer mistakes, more efficiency, and better results for projects.

Conclusion

Shop drawings are crucial in construction. They help ensure the final project matches the architect’s vision. They also make sure the project meets all requirements.

These drawings improve accuracy and coordination. They help follow rules and reduce risks. This is especially true for big and complex projects.

Investing in shop drawings is key to a project’s success. It makes sure projects are done right and with high quality. This leads to great results in the end. You can trust our remote virtual assistants at RemoteAE to assist with your firm’s construction and shop drawings.
