Frequently Asked Questions

What is building certification?

Building certification is the formal verification that construction complies with the National Construction Code (NCC) and local council regulations (NSW Fair Trading).

When should a dilapidation report be conducted?

Dilapidation reports should be done prior to construction, renovations, or nearby works to document existing property conditions and protect stakeholders from disputes.

What is an expert witness in construction?

An expert witness provides independent, professional engineering reports and testimony for legal disputes, insurance claims, or mediation (Federal Court of Australia).

How does certification benefit a project?

Certification confirms compliance with legal and safety requirements, ensuring approval by councils and reducing potential liabilities.

Are compliance audits mandatory?

While not always mandatory, compliance audits identify defects and non-conformance early, reducing risks and potential penalties.

Can these services assist in insurance or legal claims?

Yes. Dilapidation reports, defect assessments, and expert witness reports provide evidence used in insurance claims, dispute resolution, and court proceedings.

What Our Clients Say

Our reputation is built on successful project delivery and long-term partnerships. Here’s what clients say about working with Apex Civil Engineers:

Samir was of really great service with a professional approach and can do attitude. I was impressed with APEX CE’s prompt service and quick delivery time. Look forward to our next business opportunity in the near future.

I recently used the APEX CE group for some of my Construction Certificate documents (Stormwater, Parking and Erosion/Sediments Plans). They were professional and easy to deal with, had a quick and timely turnaround and was very competitive in the quoting stage. I will definitely recommend Samir and his team for future projects.

I needed to install a detention pit as part of a Stormwater condition of my DA application but Samir proposed two rainwater tanks as a more feasible and cost effective alternative. I found Samir to be extremely reliable, knowledgeable and efficient. He promptly inspected my home, then drew the OSR Plans which were immediately approved by Ryde City Council. I would recommend Samir’s service to anyone.

I found Samir apart from having a professional approach to the building work to be a like able person to deal with Thanks again Samir Martin.
