Building Consultants vs Engineering Consultants
Understanding the Difference
Many property owners, insurers, builders and legal representatives are unsure whether they require a Building Consultant or an Engineer. While both professions play important roles in the construction industry, they specialise in different aspects of a building's performance.
In many matters, a Building Consultant is the primary investigatory professional who identifies defects, non-compliant work, damage mechanisms, workmanship issues, maintenance concerns and scope requirements. An Engineer is typically engaged where specialist engineering analysis, calculations, structural design or engineering certification is required.
Building Consultancy
A Building Consultant investigates how a building has been constructed, maintained, repaired or damaged, and assesses whether it complies with applicable building standards, construction requirements and industry practice.
Building Consultants commonly investigate:
-
Building defects and non-compliant construction.
-
Water ingress and waterproofing failures.
-
Storm, hail, impact and insurance-related damage.
-
Incomplete or defective building works.
-
Roofing defects and performance issues.
-
Cause and origin of damage.
-
Scope of rectification works.
-
Builder workmanship and contract disputes.
-
Practical completion and defect liability matters.
-
Building condition assessments and expert reports.
Building Consultants are often responsible for undertaking the detailed site investigation, identifying the issues, documenting evidence, assessing compliance requirements, and preparing detailed scopes of rectification works.
Engineering Consultancy
An Engineering Consultant applies specialist engineering principles to determine whether structural or engineered elements are performing as intended and remain adequate for their designed purpose.
Engineers commonly investigate:
-
Structural adequacy of buildings.
-
Foundation movement and settlement.
-
Structural cracking.
-
Load-bearing capacity.
-
Framing and support systems.
-
Retaining wall performance.
-
Structural storm damage.
-
Structural design and certification.
-
Engineering calculations.
-
Engineering compliance certification.
Engineers are typically engaged when professional engineering judgement, calculations, structural analysis or engineering certification is required.

What Overstone Does
Overstone Pty Ltd is a Building Consultancy practice.
​
We are not an engineering firm and do not provide engineering certification, structural design services or RPEQ sign-off.
Our role is to investigate buildings, identify defects and damage mechanisms, assess building compliance, determine likely causes of observed issues, prepare detailed scopes of work and provide independent technical reporting.
​
As licensed building professionals, our assessments focus on how a building has been constructed, maintained, repaired or damaged, and what is required to rectify identified issues.
What Overstone Does Not Do
Overstone Pty Ltd does not:
​
-
Provide engineering certification.
-
Undertake structural design.
-
Produce engineering calculations.
-
Issue RPEQ certifications.
-
Certify structural adequacy.​
Where these services are required, we recommend or engage as a sub-consultant, an appropriately qualified engineering professional.
Working Alongside Engineers
Many matters require both a Building Consultant and an Engineer.
​
In these circumstances, Overstone regularly works alongside specialist engineering firms across multiple disciplines, including structural, civil, hydraulic, mechanical and geotechnical engineering.
​
This collaborative approach allows each professional to contribute within their area of expertise, ensuring clients receive both a thorough building investigation and any necessary engineering assessments.
​
In many cases, the Building Consultant identifies and documents the issues, while the Engineer provides specialist analysis or certification relating to structural or engineered components of the building. This ensures investigations remain both technically robust and cost-effective.
