Whether addressing complex structural issues or ensuring effective waterproofing systems, our team is committed to delivering high-quality outcomes tailored to your specific needs.

With over 18 years of industry expertise, our Design Practitioner consultants at MJ Engineering Projects have developed a reputation for excellence in Design Practitioner solutions.
Their approach combines innovative techniques with tried-and-tested methods to ensure the best outcomes. Our process involves.
We begin with an in-depth site inspection, assessing existing documentation to identify any structural vulnerabilities or needs, particularly related to waterproofing. This step ensures we have a complete understanding of the project scope and enables us to tailor our designs for long-term durability and compliance with industry standards.
The Design and Building Practitioners Act 2020 (DBPA) in NSW mandates that registered design practitioners prepare and declare compliant designs for Class 2, 3, and 9c buildings (apartments, boarding houses, aged care). As registered design practitioners, MJ Engineering Projects ensures designs meet Building Code of Australia (BCA) standards, improving construction quality and safety. Before construction, designs must be lodged and approved, ensuring accountability. This regulation strengthens industry standards and protects property owners from defects.
Commercial projects require strong technical expertise and strict compliance with regulations. A remedial design practitioner ensures that remedial works for office towers, retail spaces and large complexes are carefully assessed, documented and delivered in line with codes and legislation. Their role includes preparing regulated designs, coordinating with consultants and providing compliance declarations to safeguard the client’s investment.
These services also focus on clear communication between clients, contractors and stakeholders. Practitioners manage design variations, documentation and compliance obligations to minimise risks, delays and disputes. This structured approach provides confidence that remedial projects for commercial buildings progress efficiently and achieve durable, compliant outcomes.
Residential buildings, from strata complexes to multi-unit dwellings, require a tailored approach to remedial design. A design practitioner investigates building issues, prepares regulated designs and ensures documentation aligns with the Building Code and statutory obligations. Their expertise supports owners corporations and strata managers by delivering designs that address water ingress, façade deterioration and structural wear.
They also guide communication between residents, contractors and consultants. Practitioners provide design declarations, manage variations and confirm compliance across each stage of the project. By aligning solutions with regulatory frameworks, they ensure remedial works are documented, transparent and legally enforceable, protecting the value and long-term performance of residential properties.
With more than eighteen years of proven experience in remedial engineering, our firm has built a strong reputation for delivering reliable and long-lasting results. As registered design practitioners, we specialise in repairing building defects across a wide range of projects, from heritage façades that require delicate restoration to modern high-rise towers that demand technical precision.
