Industrial Structural Design & Verification for EPC and Asset Owners
Structural calculation is a critical engineering deliverable for industrial projects where safety, compliance, and constructability depend on verified load paths and code based design checks. For EPC Contractors, Plant Owners, and Operators, a structural calculation is not just an analysis, it is a reviewable calculation package that confirms structural adequacy under governing loads and combinations.

At iFluids Engineering, we deliver structural calculation services focused on industrial facilities such as pipe racks, skids/modules, platforms, equipment foundations, and brownfield structures. Our work is aligned with international design codes, real operating conditions, and the practical requirements of EPC review, client approval, and authority submission.
What Structural Calculation Covers
In an industrial context, structural calculation refers to a complete design or verification package that demonstrates the strength, stability, and serviceability of structural systems. This package is typically required during FEED, detailed engineering, design review stages, and brownfield modifications.
A structural calculation report commonly covers:
- Design basis and governing codes
- Dead, live, operating, wind, seismic, thermal, and incidental loads
- Load combinations applicable to steel and concrete structures
- Structural analysis model summary and assumptions
- Member capacity checks and utilization ratios
- Foundation bearing, sliding, and overturning checks
- Serviceability criteria such as deflection and vibration limits
For EPC and owner teams, these calculations provide confidence that structures are safe to build, safe to operate, and compliant by design.
Our Structural Calculation Services
iFluids Engineering provides structural calculation services across the full project lifecycle of new builds, expansions, and brownfield revamps.

Our scope typically includes:
- Structural analysis and design calculations for steel and concrete structures
- Verification of existing structures for revised loading conditions
- Load takedown and transfer from piping, equipment, and platforms
- Stability, strength, and serviceability checks
- Identification of overstressed members and governing load cases
- Engineering recommendations for modification or strengthening
Each engagement is approached as an engineering responsibility, not a software exercise. Calculations are reviewed for constructability and site relevance before being issued.
Structures We Commonly Calculate
Our experience spans a wide range of industrial assets, including:
- Pipe rack structural calculations for new racks and brownfield additions
- Skid and module structural calculations, including transport and lifting checks
- Equipment foundation analysis for static and dynamic loads
- Platforms, walkways, and access structures
- Pipe sleepers, bridges, and support frames
- Existing steel and concrete structures under new operational loads
This industrial focus reflects how structural calculation is actually used in oil & gas, petrochemical, LNG, power, and infrastructure projects.
Codes and Standards Basis
Structural calculations are performed strictly in accordance with the project defined design basis. Depending on location and Client requirements, the following standards are typically applied:
- ASCE 7 – Design loads and load combinations (wind, seismic, live loads)
- Eurocodes (EN 1990 / 1991 / 1993 / 1992) – Basis of design, actions, steel and concrete design
- AISC 360 – Structural steel design
- ACI 318 – Reinforced concrete design
- IS 800 / IS 456 – Indian steel and concrete design codes (where applicable)
The selected code basis is clearly stated in the calculation report to support review and approval.
What You Receive – Structural Calculation Deliverables
Clients engage iFluids for clear, audit ready deliverables that reviewers can easily follow.
Typical deliverables include:
- Structural calculation report (Design basis to conclusion)
- Load summaries and governing combinations
- Analysis results and member/foundation checks
- Serviceability verification where applicable
- List of critical observations and recommendations
Deliverables are issued in review friendly formats suitable for EPC coordination, Client sign-off, and authority submission.
What We Need From You
To execute structural engineering calculations efficiently, we typically require:
- General arrangement drawings or models
- Equipment weights and piping loads (where applicable)
- Material grades and structural framing details
- Project design basis (wind, seismic, load combinations)
For brownfield projects, As-Built verification data significantly improves accuracy and avoids rework.

Frequently Asked Questions
A structural calculation report summarizes the design basis, load cases, load combinations, analysis results, and design checks. It allows EPC, client, and authority reviewers to verify capacity, stability, and serviceability with confidence.
Structural calculation services are required during FEED and detailed design, for design reviews, and whenever layouts or loads change. They are also essential for brownfield tie-ins where existing structures must be verified for new loads.
The code basis depends on project requirements and location. Common references include ASCE 7 for loads, Eurocodes for basis and material design, and AISC or ACI standards for steel and concrete structures.
Minimum inputs include GA drawings, loading data, material specifications, and the project design basis. As-built information is critical for accurate brownfield structural calculations.
Yes. Structural adequacy checks are routinely performed for revamps and expansions to verify member capacity and identify strengthening requirements where limits are exceeded.
Deliverables include the structural calculation report, governing load combinations, design checks, serviceability verification, and clear engineering recommendations.
