Customised Shed Slabs – Structural Engineering Services

Introduction

Mellan Consulting Engineers offers specialised structural engineering services for customised shed slabs, delivering safe, durable, and site-specific solutions for a wide range of applications. Unlike standardised  slab drawings provided by many shed manufacturers, our engineering designs address the complexities of challenging site conditions, including clay foundations, rock substrates, proximity to retaining walls, steep slopes, and nearby structures like pools.

Standard slab designs often fail to meet specific site requirements, potentially leading to structural issues and non-compliance with Australian Standards (AS1170, AS2870, AS3600). Our expertise ensures that your shed slab is designed correctly from the outset, avoiding costly modifications and ensuring compliance with local council regulations.

When Do You Need a Customised Shed Slab?

• Clay Foundations: Reactive or expansive soils pose a significant risk of differential movement, heaving, and cracking in standard slab designs. To mitigate these risks, our engineering designs incorporate stiffened raft slabs, deeper edge beams, and controlled drainage systems. Depending on the soil classification (Class M, H1, H2, or E under AS2870), we adjust reinforcement and slab thickness to minimise movement and maintain long-term structural integrity.
• Rock Substrates: When rock is encountered close to the surface, conventional footing designs may not provide adequate anchorage. Our designs incorporate bored piers or rock sockets, ensuring the necessary load transfer and foundation stability. We also consider breaking out shallow rock where required to achieve uniform support conditions.
• Proximity to Retaining Walls or Steep Slopes: Building near retaining walls or embankments requires special attention to soil pressure, stability, and load distribution. We assess the potential for lateral movement and design slabs with deepened edge beams, ground anchors, or pier supports to prevent structural failure.
• Nearby Structures (e.g., Pools): Close proximity to pools or existing buildings demands engineering solutions to prevent structural interactions. Our designs include expansion joints, isolated footings, and load transfer considerations to ensure the safety and integrity of both the shed slab and adjacent structures.
• Non-Standard Loads & Usages: For sheds supporting heavy machinery, high storage loads, or specialised equipment, a tailored slab design is critical. We calculate point loads, uniform distributed loads, and dynamic loading factors, specifying thicker slabs, denser reinforcement, and stronger concrete grades to meet structural demands.

Key Structural Engineering Services

• Site Assessment & Soil Analysis: Reviewing geotechnical reports and assessing site conditions to inform the shed slab design.
• Customised Structural Design: Producing detailed engineering drawings and specification for non-standard site conditions.
• Bored Pier Design & Integration: Introducing bored piers where rock substrates or unstable soils are present to enhance structural stability.
• Load-Bearing & Stability Analysis: Ensuring the shed slab can support anticipated loads and maintain long-term performance.
• Material Specification: reinforcement options, and structural components.
• Construction Support & Inspections: Providing guidance to builders and verifying compliance during the construction phase.
• Certification & Council Compliance: Preparing all necessary documentation for council submissions and ensuring regulatory adherence.
