The Complete Shop Drawings and Fabrication Detailing Process

We use a proven five-step process for our Shop Drawings and Fabrication Detailing to deliver projects on time and at the highest quality. This approach transforms design documents into a manufacturing-ready information package.

Step 1: Design Intent Analysis & Input Review

  • We initiate the process by conducting a thorough review of all design documents, including architectural, structural, and mep drawings.
  • Our team identifies all fabrication requirements, standards, and potential coordination issues upfront.
  • We clarify any ambiguities with the design team to establish a clear and accurate basis for detailing.
  • A detailed project execution plan, outlining milestones and deliverables, is created and shared.

Typical Duration: 3-5 business days.

Step 2: 3D Model Development for Fabrication

  • We develop a highly detailed and accurate 3D BIM Modeling of the components to be fabricated using specialized software.
  • This intelligent model contains all necessary information, from material grades and dimensions to weld types and finishes.
  • The model is used to verify fit-up and identify potential constructability issues before any drawings are created.

Typical Duration: 5-9 business days.

Step 3: Detailed Drawing & Spool Generation

  • Our team extracts all necessary shop drawings directly from the approved 3D model.
  • This includes assembly drawings, single-part drawings, erection plans, and piping spool drawings.
  • All drawings are automatically populated with accurate dimensions, annotations, and bills of material.

Typical Duration: 12-18 business days.

Step 4: Multi-Stage Quality & Compliance Review

  • Every drawing undergoes a rigorous multi-point check by a senior detailer to ensure accuracy and completeness.
  • We verify the entire drawing set against the original design drawings and all applicable codes and standards.
  • A final check ensures that all client-specific drafting standards have been perfectly implemented.

Typical Duration: 7-11 business days.

Step 5: Final Package Delivery & Shop Support

  • The final, approved drawing package is delivered in all required formats (PDF, DWG, NC files).
  • We remain available during the fabrication and installation phases to provide technical support and respond to RFIs.
  • A 60-day post-delivery support window is included for any clarifications needed by the shop or field teams.

Typical Duration: 3-5 business days.

Frequently Asked Questions about Shop Drawing and Fabrication Detailing Services

The purpose of Shop Drawings and Fabrication Detailing is to translate design intent into precise instructions that a fabricator can use to manufacture, assemble, and install components.

A regular piping drawing (like a P&ID or isometric) shows the overall layout and flow. A spool drawing is a detailed fabrication drawing for a specific, prefabricated section of that piping system. It includes all necessary dimensions, material info, weld details, and part numbers for a single assembly "spool."

For our Shop Drawings and Fabrication Detailing, we primarily use Tekla Structures and Advance Steel for structural work, and Autodesk Revit for MEP.

Our mep shop drawings are incredibly detailed. They include precise dimensions, elevations, material specifications, connection details, support locations, equipment schedules, insulation thicknesses, and any other information required for error-free fabrication and installation.

The timeline depends entirely on the project's scale and complexity. A small structural frame might take 2-3 weeks, whereas the complete mep shop drawing services for a large hospital could take several months. We always provide a detailed schedule upfront.

Absolutely. This is one of our core strengths. We specialize in providing fabrication detailing services for custom equipment, complex architectural features, and unique structural connections that require a high degree of precision and problem-solving.

You will receive a complete package including PDFs, DWGs, and crucial manufacturing files like NC1/DSTV, which are key outputs of our Shop Drawings and Fabrication Detailing.

Before starting our work, we perform a thorough coordination and clash detection review of the design models. We identify and help resolve potential conflicts between our scope and the structural, architectural, and other mep drawings to ensure our fabricated components will fit perfectly on site.

Yes. Our team is proficient in a wide array of international standards (AISC, Eurocodes, BS, etc.), ensuring our Shop Drawings and Fabrication Detailing is globally compliant.

Our service doesn't end with delivery. We provide ongoing support to the fabrication shop and field teams, promptly responding to any RFIs (Requests for Information) and providing clarifications to ensure a smooth and efficient manufacturing and installation process.
