What are Fabrication Drawings?

Fabrication drawings also referred to as shop drawings are detailed technical drawings used to guide the fabrication and assembly of structural and architectural steel components. They are a critical part of the construction process, translating design intent into buildable parts that can be fabricated/welded in a workshop and erected on site.

These drawings are produced during the steel detailing phase, a specialised process that involves converting structural and architectural design drawings into shop-ready documentation. Steel detailing ensures every bolt, weld, cut, and component is accounted for — with precise dimensions, materials, and fabrication standards clearly defined.

Key Deliverables in Fabrication Drawings

General Assembly (GA) Drawings

• Provide an overall view of the steel structure or system.
• Show how different components (beams, columns, bracings, plates) come together.
• Include section views, elevations, and location references.
• Used for coordination, approval, and on-site installation reference.

Assembly Drawings

• Detail how multiple steel parts are welded or bolted together to form a sub-assembly (e.g., a beam-to-column connection).
• Specify weld types, bolt sizes, hole positions, and plate configurations.
• Often used by fabricators during pre-assembly in workshops.

Single Part Drawings (Shop Drawings)

• Show each individual steel component to be fabricated (like a plate, flange, or stiffener).
• Include exact dimensions, material grade, surface treatment, and cutting instructions.
• Typically include flat patterns for CNC cutting.

How are Fabrication Drawings produced?

At Restoric Design, we specialise in producing high-precision fabrication drawings using Autodesk Advance Steel, an industry-leading 3D modeling software tailored for structural steel detailing.

Our process begins with a careful review of architectural and structural design, followed by the development of an intelligent 3D model that captures every beam, column, connection, and plate.

Using Advance Steel’s, we generate General Assembly (GA) drawings for approval. Once the GAs have been approved, we generate the Assembly Drawings, and Single Part Drawings directly from the model, ensuring consistency, accuracy, and full traceability across all deliverables.

Every drawing includes clear dimensions, weld symbols, bolt specifications, and material callouts, enabling seamless communication between designers, fabricators, and installers. We also provide bills of materials and NC (Numerical Control) data for CNC machines, helping streamline workshop processes and reduce production time. With a strong focus on quality control, Restoric Design ensures every drawing package we deliver is ready for immediate use on the shop floor and construction site.

Structural Steel Fabrication/Shop Drawings

At Restoric® Design, we specialise in producing structural steel fabrication drawings—also known as steel shop drawings—that are essential for the accurate fabrication and erection of steel structures. Using Autodesk Advance Steel, we create detailed 3D models and extract precise General Assembly (GA) Drawings, Assembly Drawings, and Single Part Drawings.

Our drawings include critical fabrication information such as dimensions, bolt types, weld symbols, steel grades, surface treatments, and part identifiers. This level of accuracy ensures every steel component is ready for production with minimal need for on-site adjustments, saving both time and money for fabricators and contractors.

We support a wide range of structural steel projects, including steel-framed buildings, mezzanine floors, canopies, staircases, portal frames, and balustrade systems. All of our fabrication drawings are created in accordance with relevant codes and standards, such as BS EN 1090. Our team also provides Bills of Materials (BOMs) and CNC data to streamline workshop processes and reduce lead times.

With Restoric® Design, clients gain access to accurate, build-ready steel detailing services that improve communication between designers, fabricators, and site teams—ensuring a smooth and cost-effective project delivery.

Architectural Steel Fabrication/Shop Drawings

At Restoric® Design, we provide expertly detailed architectural steelwork fabrication drawings that combine precision engineering with aesthetic intent. Using advanced 3D modeling tools like Autodesk Advance Steel, we create accurate shop drawings that support the fabrication and installation of custom architectural features.

Our drawings include essential fabrication data—such as dimensions, material specifications, weld types, finishes, and fixing methods—ensuring every element is built exactly as designed. This reduces the risk of rework and ensures seamless integration with other building elements like glazing, cladding, or stonework.

We support a wide range of architectural steelwork applications, including feature staircases, balconies, handrails, balustrades, decorative screens, brise soleil, and entrance canopies. Every drawing package includes General Arrangement Drawings, Assembly Drawings, and Single Part Drawings, along with material schedules and finish specifications such as powder coating, galvanizing, or patination.

Our team works closely with architects, contractors, and fabricators to ensure all details align with the architectural vision and are practical to manufacture and install. With Restoric® Design, you can count on fabrication drawings that deliver both form and function—on time, and on budget.
