Background
It likely comes as no surprise that mine sites regularly use and operate heavy machinery. Some of these vehicles like the CAT 793 and Le Tourneau L1850 front loader can weigh in at around 300 tonnes. To safely and efficiently service and repair these vehicles, a Hunter Valley mining business was considering the establishment of a sheltered tyre changing facility. The facility needed to accommodate heavy machinery, ensure safe and efficient operational spaces, and withstand the mine’s challenging environmental conditions.
Advitech was engaged as part of an initial feasibility study, to develop the concept structural design for the facility. An initial site inspection was conducted with the client’s project manager to gain an understanding of their objectives and goals. We evaluated terrain conditions, site constraints, accessibility for large trucks, utilities, and proximity to critical mine operations.
Solution
After reviewing the site and project goals, we designed a solution that would meet the needs of the client and uphold industry standards.
The design of a reinforced concrete slab was a crucial component of the facility. Key features of this design included the extension of the existing tyre changing area and the addition of heavy-duty floor slabs, designed to accommodate the dynamic loads from mining vehicles. A feasibility assessment of fibrecrete concrete was conducted; however, it was ultimately not pursued due to cost and logistical challenges. The concrete design was undertaken in accordance with AS 3600 and CCAA T48 Design Guide to Industrial Floors and Pavements.
A portal frame structure was designed to provide shelter for the tyre-changing facility. Portal frames consist of two vertical columns connected by a horizontal or sloped beam. They offer a robust and flexible shelter solution. Our design featured a clear height of 13.5 m over a 27 x 30 m area. Uncladded side walls for access from all sides and steel framing roof purlins offered corrosion protection and enhanced roof load capacity from the elements. The portal frame structure is of mild steel standard sections and has been designed in accordance with AS 4100 requirements.
A stormwater system was also designed to manage rainwater runoff effectively, preventing operational disruptions and environmental hazards. Consideration for potential drain blockages, with alternative overflow pits and surface discharge options were integrated into the design. The stormwater system was designed in accordance with AS 3500.3.
Once the design was complete, our team gathered construction quotes from established regional construction companies to evaluate the financial feasibility of the facility upgrade. We prepared a tender summary, including scope of work, concept design, drawings and relevant specifications. An evaluation of quotes was provided to the client, based on pricing, timelines and contractor reputation.
Conclusion
The structural design of the tyre changing facility by Advitech illustrates a comprehensive approach to meeting the client’s needs while adhering to industry standards. The combination of reinforced concrete design, a strong portal frame roof structure, and an effective stormwater management system ensures that the facility will operate efficiently and safely in the demanding environment of a mine site. This case study demonstrates Advitech’s commitment to structural integrity and operational excellence in engineering projects.
