Remedial engineering services cover the diagnosis, design and management of repairs to existing buildings, from the first inspection through to the finished works. MJ Engineering Projects provides remedial engineering services across Sydney for residential, commercial and infrastructure buildings, working with strata managers, owners corporations, building owners, commercial property managers, lawyers/solicitors, insurers, builders and developers. We are engineers, not just builders. We work out the cause of a defect, design the rectification, and oversee the remedial works, with one point of contact from assessment to delivery.
Remedial engineering services sit on the consult-and-design side of building repair. The job is to understand why a building is failing, design a fix that meets code, and make sure the repair is carried out properly. That is the line between a remedial engineer and a remedial builder.
A remedial builder carries out the physical work: the concrete repair, the membrane, and the rendering. A remedial engineer diagnoses the defect, prepares the design and specification that the builder works to, and can act as superintendent to check that the work is done to that design. On most strata and commercial projects, you want both, and you want them kept separate, so the person checking the work is not the same person being paid to do it.
We provide remedial engineering services across the full lifecycle, for residential, commercial, industrial and infrastructure buildings: inspection, diagnostic report, design and specification, tendering, project management and superintendency. You can engage us for one stage or all of it.

Good remedial work starts with an accurate diagnosis. We carry out site inspections and structural condition assessments to find what is failing and, more importantly, why.
Common defects we assess include concrete cancer and spalling, where moisture corrodes the steel inside reinforced concrete and breaks the concrete apart, along with structural cracking and water ingress from failed waterproofing. The visible damage is often a symptom of a cause somewhere else, which is why a proper assessment looks past the obvious.
You get a defect report that sets out the defects, their likely causes, the recommended rectification, and an indication of cost, written so a strata committee or building owner can make a decision and budget for it.
Most of our work is on occupied buildings, which changes how remedial works are run. People are living and working in the building while repairs happen, so staging, access, noise and safety all have to be planned around them.
We work closely with strata managers, owners corporations, commercial property managers, lawyers/solicitors, insurers, builders and developers to deliver remedial construction services from scope to completion with as little disruption as possible. That means clear scopes the committee can approve, realistic programs, and a single consultant coordinating the work rather than the building manager chasing trades.
For commercial building remedial services, the same applies with tighter pressure on keeping the building operating. We plan the works around tenancies and trading hours wherever we can.
Planning remedial works on a strata or commercial building? Contact us for a condition assessment and a clear scope that your committee can act on.
Beyond design, we manage delivery and the compliance that goes with it. As superintendent, we administer the contract and check that the remedial works are built to the design, which keeps the quality check independent of the trades doing the work.
On compliance, our designs are prepared to meet the National Construction Code, the Building Code of Australia and the relevant Australian Standards, plus the Design and Building Practitioners requirements that apply to regulated designs on residential apartment buildings.
Where a building defect ends up in dispute, we also provide expert witness and forensic engineering support, with independent reports that owners corporations and their lawyers can rely on.
Key Concerns and Frequently Asked Questions About Remedial Building Services in Australia
Remedial engineering services are the diagnosis, design and management of repairs to existing buildings. That covers inspecting and assessing a building, working out the cause of defects like concrete cancer or water ingress, designing and specifying the rectification, and managing the works through to completion. It is different to new-build engineering, which designs structures from scratch.
At MJ Engineering Projects, we also provide consultations for new construction projects. We work with Tier 1 to Tier 3 builders, architects, developers and project managers, offering design review, waterproofing design input and façade and building envelope consulting.
A remedial engineer diagnoses the defect, designs the fix, prepares the specification, and can superintend the work to check that it meets that design. A remedial builder carries out the physical repairs. On strata and commercial projects, it is good practice to keep the two separate, so the party checking the quality of the work is independent of the party doing it.
A remedial building inspection is a site visit where an engineer assesses the structure, facade, waterproofing and concrete for defects, sometimes with testing or sampling where the cause isn’t obvious. It results in a condition assessment or defect report setting out the defects, their likely causes, the recommended rectification, and an indication of cost so you can plan and budget.
It depends on the defect, the scale, access, and whether the building stays occupied. A small concrete repair might take a few weeks, while a full facade or structural program on a strata block can run for months. We give you a realistic program after the assessment, once the scope is clear, rather than a generic timeframe up front.
In NSW, repairs to common property are generally the owners corporations responsibility, funded through the scheme’s levies and capital works fund, while defects inside a lot can be the owner’s. The exact split depends on the strata plan and by-laws, so confirm with your strata manager. This is general information, not legal advice.
Our role is the engineering: we diagnose, design, specify and oversee. The physical repairs are carried out by a remedial builder, whom we can help you tender for and then supervise as a superintendent. That keeps the design and quality checks independent of the trades doing the work, which protects the building owner.
