Steel Structure Modelling & Shop Drawings

Techso Engineering provides advanced 3D modelling and detailed shop drawing services for steel structures used in industrial plants, oil & gas facilities, flare systems, and modular process units.

Accurate modelling and fabrication documentation are essential to ensure efficient manufacturing, correct assembly, and full compliance with design specifications. Our services bridge the gap between structural design and workshop fabrication, delivering precise and constructible solutions.

We support fabricators, EPC contractors, and plant owners with complete structural modelling and construction documentation.

Advanced 3D Steel Structure Modelling

Steel structures are developed using industry-leading 3D modelling software, including:

Tekla Structures
Autodesk Inventor
Advance Steel (upon request)

We create fully detailed 3D models of:

Pipe racks
Flare structures
Equipment supporting structures
Access platforms and walkways
Skid frames
Towers and elevated structures
Custom industrial steel structures

3D modelling ensures:

Full dimensional accuracy
Clash-free integration with piping and equipment
Precise definition of connections
Improved fabrication efficiency
