DDEG provided expert advice on façade performance and weatherproofing compliance, ensuring the school’s modular, elevated design met high standards for moisture control and envelope integrity.
The solution delivers flood resilience, safeguarding learning spaces and enabling a swift return to education after future events.
Façade engineering is a specialised discipline focused on the design, analysis and delivery of a building’s external envelope—including curtain walls, window systems and cladding. It ensures façades meet standards for performance, weatherproofing, thermal comfort, compliance and longevity.
Effective façade engineering supports design ambition while protecting the asset against environmental, structural and regulatory risks.
A façade engineer works with architects, builders and specialist contractors to translate façade designs into practical, buildable outcomes.
This includes developing technical documentation, conducting structural and thermal analysis, detailing weatherproofing, reviewing products and shop drawings, advising on code compliance, and providing certification for complex or custom envelope systems.
They also troubleshoot construction or performance issues with independent diagnostic reviews and onsite testing, checking that the building envelope meets all required safety, amenity and regulatory standards.
We provide building solutions across most sectors Australia-wide, including:
We help design aspirations come to reality by helping architects and designers with design options, material finishes, coordination and resolving design issues.
We assist in diagnosing and resolving construction issues, optimising façades to save cost and provide advice and performance solutions to meet building codes.
We collaborate and conduct rigorous engineering checks to help the design achieve all performance and code objectives prior to fabrication and installation.
Our team are knowledgeable in various façade systems and materials across the industry, including:
Our technical advice and consulting allow you to achieve design outcomes without compromising design intent. Our breadth of knowledge will help retain ambitious architectural features or achieve cost-effective constructions.
Early engagement helps identify issues early to avoid costly redesign, capturing technical façade requirements for tender to minimise variations, saving you time and money.
