Project Gallery

MGI successfully detailed and erected the structural steelwork for the Mooney agricultural building. Modeled in Tekla, the robust, portal-frame structure utilizes precision-engineered UB and SHS sections. The project showcases efficient on-site assembly, providing a durable and functional space designed to meet rigorous industrial structural standards.

The Story

The MPGI Mooney project stands as a testament to the streamlined efficiency of modern steel construction. From the detailing phase, the structure was built in Tekla Structures, ensuring that the primary portal frame and all secondary roof bracing were fully clash-detected before a single beam left our workshop. The structural design incorporates a complex grid layout, utilizing Universal Beams (UB) for the main structural columns and spans to provide a clear, unobstructed interior. To ensure long-term stability against agricultural and environmental stresses, the design integrates various structural hollow sections (SHS) for secondary roof support, creating a lightweight yet incredibly rigid roofing system. The framing was also engineered to seamlessly integrate with Kingspan cladding panels, ensuring a weather-tight finish. The construction phase, as captured in our site documentation, highlights the precision of our engineering. Despite the challenging site conditions, the structural steel—finished in a protective red oxide—was erected with significant speed. The integration of the steel frame with the pre-cast concrete foundations and the installation of the high-level ridge ventilation monitor were executed with exact alignment, reflecting the accuracy of our initial digital model. This project demonstrates MPGI’s ability to handle the entire lifecycle of a structural steel project—from the intricacies of connection detailing to the physical reality of a standing, durable facility—while maintaining a high standard of safety and structural compliance throughout the build

Why It Should Win

This project should win because it exemplifies the ideal execution of a structural steel build: digital-to-physical harmony. By utilizing advanced 3D modeling, MPGI delivered a complex steel framework for the Mooney project that was optimized for both fabrication efficiency and rapid on-site assembly. The structure is not merely a collection of steel members; it is a precisely engineered portal frame that addresses specific agricultural functional requirements, including wide-span clearances and high-level ventilation systems. The project’s success is rooted in the meticulous detailing of every connection and base-plate anchor, ensuring that the erection process remained safe and accurate even in demanding site conditions. The Mooney build serves as a clear benchmark for how structural detailing—when performed to BS EN 1090-2 execution standards—directly contributes to project success. It proves that Marcus P. Graham Ironworks can translate sophisticated engineering into a finished, robust industrial structure that provides the client with a long-term, high-value asset, all while achieving construction timelines that keep project momentum high and site efficiency at its peak.
