Technical Drawings & Calculation Reports
Preparation and review of fabrication and erection drawings in metric and imperial systems. Complete calculation reports and technical documentation to the highest industry standards.
Professional Fabrication and Erection Drawings
We develop shop and erection drawings with the detail level needed for unambiguous execution. Each drawing includes dimensions, tolerances, weld details, bills of materials, and fabrication notes. Our drawings are designed to be self-sufficient: the shop operator or erection crew must be able to execute the work with the information contained in the drawing, without additional queries. We use Autodesk Inventor and Advance Steel to ensure dimensional accuracy and consistency between views.
- Shop drawings with complete detailing of every piece
- Erection drawings with sequencing and field connections
- Metric (mm) and imperial (inches/feet) systems per target market
- Weld details per AWS D1.1 (American market) and EN ISO 2553 (European)
- Bills of materials (BOM), piece marks, and bolt lists
- General arrangement (GA) drawings with location of all elements
Complete and Traceable Calculation Reports
We prepare complete calculation reports documenting the entire structural analysis and verification process. Each report is written to facilitate third-party review, whether by technical control offices, public administrations, or end clients. The document structure follows a logical sequence: design basis, actions, calculation models, results, verifications, and conclusions.
- Design assumptions, applicable codes, and calculation basis
- Action definition and load combinations with justification
- Calculation models: structural scheme description and software captures
- Analysis results: envelopes, force diagrams, reactions
- Limit state verifications: resistance, buckling, deflection, fatigue
- Connection checks and construction details with code references
Review of Existing Documentation
In addition to our own production, we offer technical review services for drawings and calculation reports prepared by third parties. This service is especially useful for control offices, companies that outsource engineering, or owners seeking independent verification of their project documentation.
- Fabrication drawing review: dimensions, welds, materials, tolerances
- Calculation report verification: assumptions, models, results, conclusions
- Review report with observations, non-conformances, and recommendations
- Technical coordination with the original author for observation resolution
