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.

Snaps from Model and drawings

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.

How Paradigm’s Expertise in BIM Elevates Construction Project Accuracy and Efficiency 

In the fast-paced world of construction, accuracy, efficiency, and collaboration are paramount. At Paradigm, we understand that the success of a project hinges on the precision and effectiveness of each phase, from design through to handover. As a leader in BIM services company, Paradigm has mastered the art of utilizing BIM technology to transform the way construction projects are managed, monitored, and completed. 

Building Information Modeling (BIM) is a powerful tool for streamlining the design and construction processes, enabling seamless collaboration among all stakeholders. Paradigm’s expertise in BIM ensures that every detail of a construction project is captured digitally, facilitating smoother transitions from design to completion, and optimizing future maintenance and renovations. 

Paradigm’s Proven Process for Executing BIM Projects 

At Paradigm, our approach to BIM goes beyond basic modeling. We use advanced, precision-driven strategies to ensure that every aspect of a project is accurately represented within the BIM model, improving coordination and reducing errors during the construction phase. 

Here’s how our process works: 

1. Initial Design and Planning
   The process begins with a comprehensive understanding of the project’s design requirements. Our team collaborates with architects, engineers, and contractors to define the scope and develop the BIM model, ensuring that every detail—from structure to MEP systems—is included. 

1. BIM Model Creation and Coordination
   We create a detailed and accurate BIM model that includes architectural, structural, and MEP elements. This model serves as a digital representation of the project, enabling us to detect and resolve any clashes early in the design phase, which reduces costly revisions and delays during construction. 

1. Collaboration and Real-Time Updates
   One of the key strengths of Paradigm’s approach is our emphasis on real-time collaboration. As changes are made, the BIM model is updated immediately, allowing all project stakeholders—architects, engineers, and contractors—to work from the most current data, ensuring that everyone is aligned and informed. 

1. Quality Assurance and Finalization
   Before the project moves forward to construction, we conduct thorough checks on the BIM model to ensure accuracy and completeness. This final validation ensures that the model meets all requirements and can be seamlessly handed off for construction. 

By maintaining a consistent and transparent process throughout the lifecycle of a project, Paradigm ensures that every detail is captured and executed with the highest level of precision, reducing errors and rework. 

The Real-World Impact: Paradigm’s BIM Projects and Success Stories 

Our commitment to excellence is evident in the successful execution of BIM projects. Below are examples of how Paradigm has utilized BIM to enhance construction accuracy and efficiency: 

• Case Study 1: Residential Building Projects in Europe 

In a large-scale residential project in Europe consisting of over 30 unique buildings, BIM modeling was the cornerstone of effective coordination and design integration. Each building had distinct architectural and structural requirements, necessitating a federated modeling strategy using tools like Revit and Navisworks. The multidisciplinary teams developed high-detail BIM models to ensure consistency in geometry, spatial planning, and system interfaces across the site. Intensive model coordination sessions helped identify and resolve design clashes early, particularly between MEP systems and structural layouts, significantly improving model accuracy and consultant collaboration. Customized model templates and naming conventions were enforced to maintain uniformity across all design disciplines, while shared parameter libraries enabled seamless data exchange. By centralizing all design data in a common data environment (CDE), the project team ensured real-time model updates, traceability, and alignment throughout the design process. This robust BIM modeling service laid a strong digital foundation for downstream construction, prefabrication, and long-term facility planning. 

• Case Study 2: Power Plant Structure Design with BIM Integration
  Designing power plant structures involves managing large equipment loads, seismic considerations, and complex coordination among disciplines. Incorporating Building Information Modelling (BIM) enhances this process by enabling accurate 3D modelling, clash detection, and integrated planning. With BIM, structural, mechanical, and electrical teams work collaboratively in a shared environment, reducing errors and improving efficiency. This results in faster design cycles, better material estimation, and smoother construction execution, ultimately ensuring the power plant is delivered safely, on time, and within budget. 

 Case Study 3: As Built Model from point cloud data 

Creating an accurate as-built model from 3D data is rapidly becoming a vital step in modern construction and renovation workflows. In a recent residential project, we leveraged high-resolution 3D laser scans and photogrammetry to capture existing site conditions with millimeter-level accuracy. This point cloud data was processed and converted into a detailed BIM model using Revit, allowing us to replicate the built environment exactly as constructed. Special attention was given to structural elements, MEP installations, and architectural finishes, ensuring the as-built model could serve as a reliable digital twin for facility management and future retrofits. The result was a comprehensive, data-rich model that not only reflected the physical reality of the site but also helped the client streamline maintenance planning, compliance documentation, and lifecycle asset tracking. As-built modeling from 3D data bridges the gap between physical construction and digital control, offering unparalleled precision and long-term operational value.
