Shop Drawing & Fabrication Detailing Service

The AEC Associates provides shop drawing and fabrication detailing services for general contractors, subcontractors, specialty fabricators, and design-build firms across the globe. We produce build-ready shop drawings, fabrication drawings, and detailing packages across structural steel, MEP systems, millwork, curtain wall, precast concrete, and piping disciplines — from general assembly drawings through to isometric piping drawings and installation-level details.
Shop drawings translate design intent into fabrication and installation instructions. Every drawing our team produces is checked against the original design documents, coordinated across disciplines, and reviewed for constructibility before delivery — so fabricators get what they need without revision cycles that delay the schedule.

Steel Shop Drawings

Structural steel fabrication drawings, general assembly drawings, connection details, erection drawings, and weld symbols for beams, columns, trusses, and miscellaneous metals.

Millwork Shop Drawings

Custom casework, cabinetry, joinery, and built-in furniture shop drawings with material, finish, and hardware specifications for manufacturer and installer use.

Curtain Wall Detailing

Curtain wall and facade system shop drawings — frame, glazing, panel, and anchorage details coordinated with structural and architectural models.

Precast Detailing

Precast concrete shop drawings including precast panel detailing, precast wall panel detailing, connection details, lifting inserts, and erection sequences for walls, columns, beams, and hollowcore slabs.

Piping Spool Drawings

Piping spool drawings, isometric piping drawings, and piping and instrumentation diagrams (P&IDs) for process piping, HVAC, and utility systems — including general assembly drawings for skid-mounted equipment.

Electrical BIM Shop Drawings

BIM-coordinated electrical shop drawings — conduit routing, cable tray layouts, panel schedules, equipment connections, and lighting coordination drawings.

Fabrication Drawings

Detailed fabrication drawings for structural, architectural, and MEP components — cut lists, bend schedules, weld procedures, and assembly sequences ready for the shop floor.

Inputs We Build Shop Drawings From

Architectural, structural, and MEP design drawings (2D CAD or PDF)
Revit, Tekla Structures, or other BIM models
Structural calculation packages and specification documents
Manufacturer cut sheets and product data sheets
RFI responses and submittal comments
As-built drawings for retrofit and modification work

Shop drawing showing beam connection detail — elevation, section views, enlarged details, and bill of materials

Who We Build Shop Drawings For

Who We Build Schematic Design Packages For

General Contractors — shop drawing coordination across all trades, reviewed for constructibility and clash-free before submission to the design team.
Specialty Subcontractors — discipline-specific shop drawings for steel, MEP, millwork, curtain wall, and precast subcontractors who need fabrication-ready documentation from design intent drawings.
Structural Engineers — steel and precast shop drawing packages for checking and stamping, produced to the fabricator's standards and submitted on their behalf.
Fabricators & Manufacturers — general assembly drawings, piece mark drawings, and material schedules that go directly to the shop floor.
Design-Build & Construction Management Firms — full shop drawing package management across all disciplines, from first submission through approved for construction.

What You Can Expect From Every Shop Drawing Deliverable

Shop drawing showing steel beam elevation, sections, connection details, bill of materials, and revision history

Drawings reviewed against original design documents before submission
Clash detection run across all disciplines involved in the drawing package
All dimensions, connections, materials, and weld symbols checked for completeness
Files delivered in the format your submittal workflow requires (.dwg, .rvt, .pdf)

Quality Review Process

Every schematic design drawings goes through our internal quality system before delivery:

Self Check: First check done by the individual against coordination and standards.

Peer Review: Next QC executed by peers/team members

Supervisory Check: QC by the Project Manager broadly reviewing graphics and technicalities.

This process is backed by the same International quality management system used to deliver all projects at The AEC Associates.

Frequently Asked Questions

What are shop drawings? ›

Shop drawings are fabrication and installation drawings produced by a contractor or fabricator showing exactly how a component will be manufactured and installed — dimensions, materials, connections, and assembly sequences at the precision level needed to build from.

What’s the difference between design drawings and shop drawings? ›

Design drawings communicate the architect’s or engineer’s intent. Shop drawings translate that intent into fabrication instructions — exact dimensions, material grades, weld types, and bolt patterns that a fabricator can act on directly.

What is a general assembly drawing? ›

A general assembly drawing (GA drawing) shows how multiple fabricated components fit together as a complete assembly, with overall dimensions, component relationships, and connection interfaces — without duplicating the individual piece-mark detail on separate fabrication drawings.

What is an isometric piping drawing? ›

An isometric piping drawing shows a pipe spool in 3D isometric projection with its configuration, dimensions, fittings, flanges, weld positions, and material specification — the primary document a pipe fabricator uses to prefabricate spools off-site.

What are piping and instrumentation diagrams (P&IDs)? ›

P&IDs are schematic drawings showing the piping layout, process equipment, instrumentation, and control elements of a system — schematic rather than dimensional, showing what connects to what and how the system is controlled.

What is precast panel detailing? ›

Precast panel detailing is the production of shop drawings for precast concrete wall panels — reinforcement layouts, connection details, lifting insert positions, and erection sequences — used by the manufacturer to cast and the contractor to install.

What is the shop drawing submittal process? ›

Shop drawings are submitted by the contractor to the design team for review before fabrication. The design team marks them Approved, Approved as Noted, Revise and Resubmit, or Rejected. Fabrication proceeds only once drawings are approved.

Do you manage the full shop drawing submission process? ›

Yes. We produce the drawings, track revisions through your submittal log, incorporate review comments, and resubmit until approved for construction.

What file formats do you deliver shop drawings in? ›

.dwg (AutoCAD), .rvt (Revit), .pdf for submittal sets, and .ifc for BIM coordination — confirmed at project start based on your workflow.

What sectors do you support? ›

Commercial, industrial, healthcare, hospitality, residential, infrastructure, and data center projects across the USA, UK, Canada, and the Middle East.
