Why Are Concrete Footings Needed for Transportable Buildings?

Understanding the foundational needs of transportable buildings is essential for their stability and longevity. Concrete footings play a crucial role in ensuring your structure is level, secure, and capable of withstanding various environmental conditions.

What Are Concrete Footings?

Concrete footings form the base of a foundation, bearing the weight of a building to ensure stability and durability. These foundational elements must be robust and well-constructed to withstand heavy loads and prevent any risks associated with shifting or sinking.

Essential for both in-situ and transportable buildings, concrete footings are designed to meet the structural demands of diverse environments, ensuring the long-term integrity and safety of the construction.

Types of Concrete Footings

At Instant Transportable Offices, we primarily use pre-cast concrete footings for our transportable buildings to distribute the structural load over a larger area. In cyclonic regions (Region D), we employ cyclonic footings to enhance anchorage and secure the transportable buildings against extreme weather forces as required by our Structural Engineer.   Whilst concrete footings can be poured in-situ (which is preferred by some customers), ultimately it will come down to a cost decision as to which is the best option. Pre-cast footings are made enmasse and are affordable, but transport of them to site can sometimes make it not as cost effective depending on the location of the project.

Our structural engineer will design, detail and certify footings to suit both in-situ (poured on-site) or pre-cast depending on your preference.  You should let our team members know this before and design drawings or documentation is started so that we can take your preferred option into account.

Why are Concrete Footings Needed?

Concrete footings are essential for maintaining the structural integrity and levelness of buildings. They provide a solid foundation that distributes the building’s weight evenly, preventing uneven settling or movement that could lead to structural issues. By anchoring buildings firmly to the ground, concrete footings ensure long-term stability and safety.

What’s the Difference Between Cyclonic Concrete Footings and Non-Cyclonic Concrete Footings?

Our cyclonic concrete footings are specifically designed to meet the stringent demands of Region D cyclonic conditions, providing exceptional stability and resistance. Weighing in at 4750 kg, these footings are significantly reinforced to endure the extreme wind forces encountered in such areas.

Standard concrete footings are made for areas with typical weather patterns and don’t require such extensive reinforcement, such as Region A (most of the Perth Metropolitan area). If you’re wondering whether your location requires cyclonic concrete footings, we have a detailed guide that covers the cyclonic and non-cyclonic regions in Australia to help you determine that.

Does That Mean Every Single Demountable Building Need Concrete Footings?

Determining whether every demountable building requires concrete footings involves multiple factors, such as soil type and compaction, building size, location, and specific environmental conditions like wind loadings in cyclonic regions, however 99% of the time the answer will be YES.

Here at Instant Transportable Offices, we rely upon our Structural Engineers advice to ensure full compliance with regulations and guarantee safety.

Frequently Asked Questions

What are concrete footings and why are they important for transportable buildings?

Concrete footings are foundational elements that distribute the weight of a building, ensuring stability and preventing structural issues. They are particularly important for transportable buildings to maintain levelness and integrity in various environments.

How do cyclonic concrete footings differ from standard footings?

Cyclonic concrete footings are reinforced to withstand the extreme wind forces found in cyclonic regions. They are heavier and more robust compared to standard footings, which are designed for areas with typical weather patterns.

Does every demountable building require concrete footings?

While most situations require concrete footings for demountable buildings, factors like soil type, building size, and specific environmental conditions might affect this requirement. It’s recommended to consult with structural engineers for tailored advice.
