In the architecture, engineering, and construction (AEC) field, the terms “shop drawings” and “working drawings” are often used—but many stakeholders are unsure where one ends and the other begins. While both are essential to a successful project, they serve very distinct roles in the construction process. Let’s break down their differences, applications, and how they complement each other in real-world projects.
🏗️ What Are Working Drawings?
Working drawings, also known as construction drawings, are comprehensive technical plans created during the design and planning stage of a building project. They represent the architect’s and engineer’s design intent and are typically submitted for approvals and permits.
🧾 Common Inclusions in Working Drawings:
- Site plan, floor plans, sections, and elevations
- Structural framing layouts
- HVAC, plumbing, and electrical routing
- Wall sections and construction assemblies
- Door/window schedules and material specs
📌 Working drawings serve as a “roadmap” for the construction team to follow.
🔧 What Are Shop Drawings?
Once the design is finalized, it’s time to execute. That’s where shop drawings come in. Shop drawings are component-specific and detail how individual elements will be fabricated, assembled, and installed on-site. They’re typically produced by subcontractors, fabricators, or a drafting service like McLine Studios.
🛠 Shop Drawings Typically Include:
- Detailed dimensions, tolerances, and joinery methods
- Assembly diagrams and exploded views
- Product and material specifications
- Anchor locations and installation techniques
- Manufacturer and part identification numbers
- Coordination notes with other trades (clash detection)
📌 They are critical to ensuring every piece is made exactly right—especially in custom fabrication.
🧱 Examples of Where Shop Drawings Are Used
At McLine Studios, we create shop drawings for various trades and applications:
- ✅ Millwork Shop Drawings: For custom cabinetry, wood panels, shelving, and built-ins.
- ✅ HVAC Ductwork: Detailing bends, transitions, and connections.
- ✅ Steel Fabrication: Connection points, weld types, and bolt layouts.
- ✅ Cladding Systems: For façade panels and anchors.
- ✅ MEP Coordination: Avoiding clashes between plumbing, ductwork, and electrical systems.
🆚 Shop Drawings vs Working Drawings – A Side-by-Side View
| 📌 Aspect | Working Drawings | Shop Drawings |
|---|---|---|
| Created By | Architects & Engineers | Contractors, Fabricators, Drafting Services |
| Purpose | Communicate design intent | Communicate fabrication & installation details |
| Level of Detail | General – entire building | High – individual components |
| Approval Used For | Permits, tendering, and coordination | Fabrication, construction team review |
| Flexibility | Conceptual and adaptable | Specific to products/materials in use |
| Examples | Site layout, elevations, structural plans | Millwork, steel detailing, panel layouts |
🚧 Why This Difference Matters on Site
Confusing or overlooking the roles of each drawing type can lead to major coordination issues, fabrication errors, or even failed inspections. That’s why collaboration between design professionals and drafting experts is critical. Working drawings set the stage, while shop drawings execute the vision—with complete clarity.

🔍 Final Thoughts
In short, working drawings tell you what to build, and shop drawings tell you how to build it. Both are essential—but they must be developed, reviewed, and coordinated with care.
