MJ Engineering Projects provides remedial building services across Sydney for strata, commercial, residential and infrastructure buildings. We are the engineers behind the repair: we diagnose why a building is failing, design a rectification that achieves BCA compliance, then tender the works and superintend the contractor through to sign-off. One point of contact from the first inspection to the finished repair.
Remedial building services deal with existing buildings that have defects: water ingress, concrete spalling, facade deterioration, structural cracking, failed balustrades, and non-compliant cladding. New-build engineering asks how to construct something. Remedial engineering asks why something built is now failing, and what repair will actually hold.
The distinction that matters most to our clients is between a remedial engineer and a remedial builder. The builder performs the physical work: the concrete repair, the membrane, and the render. The engineer diagnoses the defect, prepares the design and specification that the builder works to, and superintends the works to check they match that design. On strata and commercial projects, you want both, and you want them separate, so the person verifying the repair is not the person being paid to build it. MJ Engineering Projects is the engineering side of that equation.
Our remedial services run across the defects Sydney buildings most commonly present:
Before any of that, we work out what is actually wrong. Building condition assessments and diagnostic investigations identify the cause of a defect rather than its symptom, because a repair aimed at the symptom tends to come back, usually larger.
With over 18 years of remedial engineering expertise, MJ Engineering Projects has built a strong reputation for delivering effective, practical and compliant remedial solutions. Our process is designed to address the root causes of building issues, ensuring long-term durability, safety and compliance with the National Construction Code and relevant Australian Standards.
Our structured approach combines investigative techniques with proven remedial methodologies to provide certainty for owners, strata managers, and building stakeholders.
Every rectification we design is documented to achieve BCA compliance under the National Construction Code and the relevant Australian Standards. That matters more in remedial work than most owners expect, because repairs to class 2 buildings in NSW now sit inside a regulated framework: under the Design and Building Practitioners Act 2020, regulated designs must be prepared and declared by a registered design practitioner. We hold that registration (DEP0002740), so the compliance paperwork exists before the contractor starts, not after a certifier asks for it.
BCA compliance remedial services also protect you later. A documented, compliant repair supports insurance, resale and any future defect claim. An undocumented patch does the opposite.
Consulting fees scale with the building and the defect, and are always quoted as a fixed fee proposal broken into stages, so an owners corporation can approve the diagnosis first and commit to design, tender and superintendence once the findings are known. On the construction side, the tender process shows you the market price for the works rather than a single contractor’s quote.

The builder does the physical repair. The engineer works out why the building failed, designs the rectification, and checks the builder’s work against that design. Keeping the two separate means the person certifying the repair has no financial interest in cutting corners on it.
Start with a diagnostic inspection, not a contractor’s quote. A quote prices a repair to the visible symptom; an inspection identifies the cause, which is frequently somewhere else. From there, you will know whether you are dealing with maintenance, a targeted repair or a major rectification project.
Both. We are engaged directly by owners corporations, by strata managers on their behalf, and by commercial building owners, facility managers and government bodies. Reporting is written for a committee to follow, not just for engineers.
Yes. We can review the existing report and progress the project through regulated design, tender and superintendence. We first confirm that the investigation and diagnosis are sufficient and that the proposed scope addresses the underlying cause. Further inspection or testing may be required where information is incomplete.
Yes. Rectification designs are documented to the National Construction Code and relevant Australian Standards, and for class 2 buildings, they are prepared and declared under our NSW design practitioner registration (DEP0002740). You receive the compliance documentation as part of the deliverables.
Less than they should be, when planned properly. Staging, access and noise windows are set in the specification and contract before the builder is appointed, and we hold the contractor to them during delivery. Residents get notice of what is happening, where and when it will end.
