Shop drawings are the detailed technical drawings that manufacturers, fabricators, and contractors prepare before any actual work begins on site. It shows exactly how a component will be built, installed, or assembled. So a shop drawing is not the same as a design drawing. It goes one step further and shows the “how” behind the “what.”
At Paradigm Outsourcing, shop drawing services are provided across a wide range of trades and construction types. Whether it is a steel structure in the UK, a precast element in Canada, or a millwork cabinet in the USA, the same level of accuracy is expected every time.
Why Shop Drawings Matter on Every Project
Here’s the thing — many construction errors happen because someone assumed something that was never clearly communicated. Shop drawings close that gap. They are reviewed and approved by engineers or architects before fabrication starts. So problems are caught on paper, not on site.
This matters a lot when projects span multiple countries or time zones. For clients in India, New Zealand, Italy, Russia, and Australia, having a dependable outsourcing partner means their projects stay on schedule even when local drafting resources are stretched thin.
Shop drawings are also a compliance requirement on most commercial and industrial projects. Submitting them is part of the RFI and submittal process. They confirm that the contractor has understood the design intent correctly.
Our Shop Drawing Services
All services listed below are handled in-house by experienced CAD and BIM drafters. Turnaround times are kept tight, and each drawing set goes through internal quality checks before delivery.
Architectural Shop Drawings
Used for façade elements, curtain walls, doors, windows, and interior fit-outs. These drawings capture the exact dimensions and installation details that the design drawings leave open. Our Architectural Shop Drawings service covers both commercial and residential projects.

Frequently Asked Questions (FAQ)
What is a shop drawing, and how is it different from a construction drawing?
The architect or engineer prepares a construction drawing and shows the design intent. The contractor or fabricator prepares a shop drawing and shows how a specific component will actually be built or installed. Shop drawings are submitted for approval before fabrication begins.
How long does it take to complete a set of shop drawings?
It depends on the scope. A small millwork package might take two to three days. A full structural steel shop drawing set for a multi-story building could take two to four weeks. We always confirm turnaround times before a project starts.
Do you work on projects outside India?
Yes. Most of our clients are based in the USA, UK, Canada, New Zealand, and Australia. We work in their time zones when needed and follow the local codes and standards they specify.
What file formats are used for delivery?
Drawings are typically delivered in PDF and AutoCAD DWG formats. Revit files are also available for BIM-based projects. We match whatever format the client’s review process requires.
Can you handle revisions after the first submission?
Yes. Revisions are a normal part of the shop drawing process. We track revision history and update drawings accordingly. Most revisions are turned around within one to two business days.
What software is used?
Primarily AutoCAD and Tekla Structures for steel and structural work. Revit is used for BIM-based projects. SolidWorks and other tools are used as needed, depending on the trade.
Is there a minimum project size?
No. We work on small single-trade packages and large multi-discipline projects alike. If you have a drawing need, reach out, and we will confirm if we can help.
