Pre-Engineered Buildings (PEMBs) are transforming modern construction — delivering faster schedules, cost efficiency, and high structural performance for industrial, commercial, and warehouse projects. Behind every successful PEMB is a highly accurate set of Tekla shop drawings, the critical link between design intent and steel fabrication.
This guide covers everything engineering, fabrication, and construction teams need to know about Tekla-driven shop drawings for PEMBs — from scope and workflows to benefits, deliverables, and industry best practices.
| Feature / Capability | Direct Benefit | Business Impact | Primary Beneficiary |
|---|---|---|---|
| Accurate 3D modeling (tapered & built-up members) | Eliminates fit-up errors; true-to-fabrication geometry | Reduces rework, saves material & labour costs | Fabricator / Contractor |
| Automated connection detailing | Standardised, repeatable connection designs | Faster detailing cycle; fewer engineering queries | Engineer / Fabricator |
| CNC / NC file output & CNC-ready data | Directly drives shop machinery with minimal manual input | Accelerates production; improves part consistency | Fabricator |
| Clash detection & model coordination | Identifies interferences before fabrication | Minimises site delays and costly adjustments | Contractor / Engineer |
| Automated reports (bolt lists, cut lists, BOM) | Fast, accurate procurement and production planning | Improves cash flow and inventory management | Fabricator / Procurement |
| Erection & assembly drawings with sequence | Clear site guidance; match-marked parts | Faster, safer erection; fewer field errors | Contractor / Site Team |
| Material optimisation & weight reports | Right-sizing of members and reduced scrap | Lower material cost; reduced transport loads | Owner / Fabricator |
| Model-based approvals (MBE) | Faster sign-offs with fewer RFI cycles | Shorter lead-times; predictable schedules | Engineer / Client |
| Traceability (mark numbers & revision control) | Full part history & easy QA/QC audits | Improved warranty support & compliance | Fabricator / QA |
What Are Tekla Shop Drawings for PEMBs?
Tekla Structures is a leading 3D BIM software specifically tailored for steel structures. When used for PEMBs, Tekla enables detailers to generate:
- Fabrication-ready shop drawings
- Connection details
- Erection drawings
- Assembly drawings
- Reports and CNC data
Because the entire model is highly precise and fully coordinated, Tekla shop drawings eliminate the errors and surprises common in 2D detailing workflows.
Tekla ensures the structure you build onsite perfectly matches the design model — with connection intelligence built-in.
Role of Shop Drawings in PEMB Projects
PEMBs consist of:
- Primary frames (rafters & columns)
- Secondary frames (purlins, girts, braces)
- Cladding & roofing systems
- Anchor bolt systems
- Mezzanines and add-ons
Shop drawings translate the 3D BIM into manufacturing language, giving fabricators everything needed to cut, weld, assemble, and erect the steel accurately and efficiently.
Purpose of Tekla Shop Drawings:
| Stage | How Tekla Drawings Help |
|---|---|
| Fabrication | Exact dimensions, cuts, bolt holes, plate sizes, weld specs |
| Assembly | Clear part identification, match-marking, bolt lists |
| Site Erection | Field connections, erection sequencing, anchor bolt positions |
| Quality Control | Clash-free geometry, verified member interactions |
What Do PEMB Tekla Shop Drawings Include?
A complete set typically contains:
Member & Assembly Drawings
- Columns and rafters with haunch geometry
- Built-up tapered beams
- Purlins, girts, struts, bracings
- End-wall & lean-to assemblies
Connection Details
- Welded end plates
- Moment connections
- Base plate & anchor layouts
- Clip angles, shear connections
- Roof and wall ties
General Arrangement / Erection Plans
- Frame line layouts and elevations
- Roof/floor levels and grids

- NC/CNC files for automated machines
Every component is assigned a unique mark number for traceability from factory to site.
Why Tekla is Preferred for PEMBs
| Feature | Value for Fabricators & Contractors |
|---|---|
| Highly accurate tapered modeling | Perfect fit for built-up members |
| Automated connections | Faster detailing → fewer errors |
| Clash detection | Prevents onsite rework |
| BIM-to-fabrication workflows | CNC + assembly optimization |
| Material optimization | Reduces steel waste |
| Global collaboration | Smooth coordination between teams |
Tekla ensures the economy of PEMBs translates into real-world material savings and predictable schedules.
The Tekla Workflow for PEMB Shop Drawings
A typical process for pemb shop drawings:
Structural Inputs
Design model, load data, design calculations, vendor specifications
3D Tekla Modeling
Primary & secondary steel, connections, roofing systems
Clash Checks & Coordination
Review with engineers & fabricators
Automated Drawing Extraction
Fabrication drawings, reports, CNC files
Quality Review
Adherence to codes, standards, and tolerances
Approval & Release for Fabrication
Benefits to Fabricators
- Repeatable, standardized detailing for modular PEMBs
- Zero ambiguity → smooth production
- Quicker shop floor execution
- Reduced scrap and welding rework
- Faster project turnaround and higher profitability
With automated reports, fabricators get everything from bolt lists to advanced bill-of-materials in seconds.
Benefits to Contractors & Site Teams
- Accurate schedule planning
- Faster and safer erection
- Minimal field modifications
- Clear sequencing and crane movement optimization
Erection efficiency is one of the greatest advantages of accurate Tekla shop drawings.
Industry Standards Considered
Shop drawings are usually developed per:
- AISC / MBMA (US)
- IS Codes (India)
- BS / Eurocodes (Europe)
- ASTM, AWS (materials & welding)
Approved drawings meet both design compliance and fabrication best practices.
Future of PEMB Shop Drawings: Model-Based Delivery
More PEMB companies are moving to:
- Connected BIM workflows
- Model-based approvals (MBE)
- Data-driven fabrication automation
Tekla will remain central to this shift — enabling faster design-to-deliver cycles.
Conclusion
Pre-engineered buildings demand precision — and Tekla shop drawings deliver it. With intelligent 3D modeling, automated detailing, and fabrication-ready documentation:
✔ Errors drop
✔ Productivity rises
✔ Onsite installation becomes faster and cleaner
✔ Steel performance matches design intent perfectly
For PEMB fabricators and contractors, partnering with an expert Tekla detailing provider is no longer optional — it’s the key to executing projects reliably and profitably.
