A static equipment foundation is a structure, often made of reinforced concrete, designed to support non-moving industrial equipment like pressure vessels, tanks, and heat exchangers. This blog walks through the journey from concept to construction-ready documentation, highlighting how digital tools like Autodesk Revit transformed the process.

Structure Type

Equipment foundations for static equipment such as pressure vessels, heat exchangers, storage tanks, columns, reactors, etc.

Scope of Work

• Structural analysis and design of equipment foundation

• 3D modelling of the foundation

• Preparation of structural drawings and bar bending schedule

Design Challenges

Precision Requirements

Static equipment demands tight tolerances for anchor bolt placement and baseplate leveling. Achieving this in a congested rebar environment was a key challenge.

Rebar Congestion

The pedestal had high reinforcement density due to seismic and wind load requirements. Coordinating rebar with embedded items required meticulous detailing.

Interdisciplinary Coordination

Mechanical and electrical systems introduced embedded conduits, and equipment had to be integrated without compromising structural integrity.

Constructability

The foundation design had to be practical for site execution, with clear bar bending schedules and minimal rework.

Design Factors

• Equipment properties: The foundation’s design is heavily influenced by the equipment’s weight, dimensions, and shape.

• Operational loads: Must account for the equipment’s weight, as well as forces from internal pressure, external loads, thermal expansion, and potentially seismic activity.

• Soil conditions: The type of soil and its bearing capacity determine the foundation’s size and depth.

• Presence of nearby structures: Presence of nearby structures is another factor which determines the size of the foundation.

Engineering Strategy

Structural Design

The type of equipment and shape of foundation required was identified. Isolated footing was provided for foundation with light to moderate loads with good soiling conditions and combined footings or raft when equipment is closely spaced or soil bearing is low. Loads and load combinations were analyzed as per Euro code and Algerian code. The foundation was designed to ensure stability, minimize settlement and loss of contact, and resist bending moments, shear forces, and crack width.

3D Modeling in Revit

The entire foundation including pedestal, anchor bolts, and rebar was modeled in Revit. This enabled real-time clash detection and seamless coordination with other disciplines.

Rebar Detailing

Revit’s rebar tools allowed us to visualize bar placement, optimize lap lengths, and ensure clear cover compliance. Hooks, bends, and splices were modeled accurately for fabrication and to prevent clashes with anchor bolts.

Documentation

Construction drawings and BBS were extracted directly from the Revit model, reducing manual errors and improving site efficiency.

Conclusion

This project showcased the power of integrated design and digital modeling. By combining structural engineering with BIM tools like Revit, we delivered a foundation that was not only structurally sound but also construction-ready and coordination-friendly.

Introduction

Circular platforms are an integral part of refinery structures. They are used to support heavy equipment, pipelines, and access systems, while also ensuring safety and stability for operational needs. Preparing accurate designs and detailed drawings for such platforms requires a blend of engineering expertise and advanced modelling tools.

Project Overview

In our company, we have successfully executed many refinery projects involving circular platforms and their foundations. Each project required close coordination with process, piping, and mechanical departments to meet the complex functional requirements.

Structural Analysis and Design

The process begins with a thorough structural analysis. Circular platforms often need to carry eccentric loads from pipelines, vessels, and rotating equipment. Our engineering team carefully evaluates:

• Load combinations (dead, live, equipment, wind, seismic, piping, snow, etc.).

• Foundation interaction, considering soil conditions.

• Dynamic effects, especially where rotating machinery is involved.

We ensure that the design complies with industry standards and project-specific guidelines. The outcome is a safe, efficient structure capable of long-term performance.

Foundations are critical for refinery platforms, especially since they support concentrated loads. Our detailing covers:

• Raft and isolated footing design.

• Anchor bolt layouts and embedment details.

• Reinforcement schedules for concrete works.

• Special detailing for vibration and heavy equipment loads.

Modelling and Detailing

Once the design is finalized, we will be converting concepts into highly detailed 3D models.

• Model primary and secondary steel members with precision.

• Generate detailed connections suitable for fabrication.

• Prepare general drawings showing anchor bolts, pedestals, and reinforcements.

• Create clash-free models by coordinating with piping and equipment layouts.

The 3D model ensures better visualization, quick revisions, and high-quality deliverables for both fabrication and erection.

Deliverables & Results

Upon completion, the following engineering outputs are generated:

• Analysis and Design results

• 3D Model

• 2D general arrangement drawings

• Erection and fabrication drawings

• Design calculation report

Conclusion

Over the years, we have successfully completed many refinery projects involving circular platforms. Each project presented unique challenges, from congested layouts to strict safety requirements. Our combination of structural analysis, design expertise, and Tekla modelling has helped us deliver accurate, constructible, and cost-effective solutions.

By integrating advanced analysis with Tekla modelling, we provide end-to-end solutions that ensure structural safety, fabrication accuracy, and ease of construction on-site.
