ENGINEERING CERTAINTY. DELIVERED.
A well-designed deck needs to do more than create an attractive outdoor space. The joists, bearers, posts, connections and foundations all need to work together to safely transfer loads into the supporting ground or existing building.
Engineering On Demand provides structural engineering for Decking Perth, from ground-level residential decks through to elevated decks, balconies and custom timber structures.
Our services can include structural design, timber member sizing, footings, connections, engineering drawings and certification for projects throughout Perth and Western Australia.
The decking boards are only the visible surface of a much larger structural system.
Below them, joists transfer loads into bearers, which are supported by posts, walls or other structural elements. Those loads ultimately need to reach foundations or an existing building capable of supporting them.
A Deck Engineer Perth considers this complete load path when developing the structural design.
Engineering On Demand can provide engineering for new decks, raised decks, deck extensions and custom timber structures where project-specific structural design is required.
Timber is capable of forming much more than conventional residential decking.
Engineering On Demand provides structural engineering for Timber Structures Perth, including outdoor structures, timber platforms, pergolas, shelters, walkways and other custom timber construction.
The engineering approach depends on the structure itself, its intended use, environmental exposure and how loads are transferred through the timber members and connections.
The NCC structural provisions recognise both engineered timber design and residential timber-framed construction through referenced Australian Standards.
Joists support the decking surface and transfer loads into the bearers or other supporting structure below.
Member size and spacing depend on the deck geometry, spans, timber properties, loads and structural arrangement.
Larger open areas or unusual deck configurations can require project-specific Deck Design Perth rather than standard span-table solutions.
Posts transfer loads from the deck framing into the foundations.
Their size, height, spacing and restraint all influence how the deck performs, particularly for elevated structures where lateral stability becomes increasingly important.
Bolts, brackets, fixings and other connections transfer forces between joists, bearers, posts and the existing building.
The NCC specifically addresses the attachment of decks and balconies to external walls as part of its structural provisions.
The foundation system ultimately supports the deck and transfers its structural reactions into the ground.
Footing design can depend on post loads, deck height, soil conditions and the structural arrangement above.
Where required, site classification information can be incorporated into the engineering.
Provide the proposed deck layout, dimensions, site information and available architectural drawings.
We assess the structural arrangement, site conditions and applicable project requirements.
Joists, bearers, posts, bracing, connections and foundations are engineered as required.
The structural requirements are documented for construction and approval.
Where included within our scope, the engineering documentation can support the applicable building approval process.
Structural engineering documentation and certification are issued in accordance with the agreed project scope.
Standard timber span tables can provide practical solutions for conventional construction, but not every project fits neatly within standard arrangements.
Large spans, elevated decks, unusual geometry, concentrated loads or architectural requirements can require project-specific structural engineering.
Engineering On Demand can develop a custom structural solution around the proposed deck dimensions, architectural concept and site conditions.
Where structural certification is required, Engineering On Demand can provide engineering documentation within our agreed structural scope.
This can include structural calculations, member design, footing requirements, connections and engineering drawings.
Structural engineering certification should be distinguished from statutory building certification provided by a registered building surveyor where that is required for the building approval process.
Not every deck necessarily requires project-specific engineering. The requirements depend on the structure, site and applicable approval pathway. Larger, elevated, unusual or structurally complex decks are more likely to require specific structural engineering.
Yes. We can engineer elevated decks, including joists, bearers, posts, bracing, connections and foundations.
Yes. The connection between the deck and existing building can form an important part of the structural design. The NCC specifically identifies attachment of decks and balconies to external walls within its structural provisions.
Yes. A freestanding deck can be designed as an independent structure with its own posts, framing, bracing and foundations.
Yes. Our Timber Structures Perth services can include pergolas and other custom timber structures where structural engineering is required.
Potentially, but the additional structural loads from the patio need to be considered. Where both are being constructed together, we can engineer the deck and patio as a coordinated structural system.
Yes. We can undertake structural assessment of existing decking where sufficient access and evidence are available. Further investigation may be required where important structural components are concealed.
Yes. Where included in the project scope, we can provide the structural documentation and assist with the applicable approval process.
