Principal-led civil, structural
and forensic engineering
Who we are
Independent engineering advice for complex,
constrained and high-value projects across
New South Wales, Victoria and Queensland.
Cadmus Engineering is a boutique consultancy providing civil, structural and forensic engineering services across New South Wales, Victoria and Queensland. We work with developers, architects, builders, asset owners, insurers and legal professionals on projects requiring experienced technical advice and practical engineering solutions.
As a focused, principal-led practice, Cadmus Engineering provides clients with direct access to senior engineering expertise. This allows for clear communication, efficient decision-making and engineering solutions that respond to both technical requirements and project realities.

Selected Projects
The project required a deep basement excavation immediately adjacent to neighboring heritage structures on a highly constrained, steeply sloping site with unstable ground conditions.
Cadmus engineered an anchored continuous piling shoring system combined with optimized slab framing. This minimized site disturbance, eliminated structural movement risks to adjacent properties, and maintained the architect’s open floorplan design.

Core services
Structural Engineering
Structural design and documentation for architecturally designed projects, small and medium-rise residential developments, industrial warehouses, commercial and retail buildings, childcare centres, medical centres, new dwellings, alterations and additions, basements, shoring, retaining structures and remedial works. Our designs focus on safety, efficiency, buildability and architectural coordination.
Civil Engineering
Civil and infrastructure design for residential, commercial, industrial, sporting and recreational developments. Our services include stormwater drainage, on-site detention systems and basins, earthworks, pavements, subdivision infrastructure, retaining walls, pedestrian bridges and associated infrastructure. Our designs are coordinated with architectural, authority, site and construction requirements.
Forensic Engineering
Independent investigation of structural defects, movement and failures, supported by clear causation analysis, practical remedial strategies and defensible technical reporting. Our services include structural inspections, defect diagnosis, failure investigations, expert reporting and remedial engineering advice. We provide clear, evidence-based conclusions to support informed technical, legal and commercial decisions.
About us
Cadmus Engineering is a civil, structural and forensic engineering consultancy specialising in complex, risk-sensitive and high-value projects.
Every project receives consistent senior involvement from commencement through to delivery. This approach supports clear accountability, efficient decision-making and practical engineering solutions.
Our work is guided by experienced engineering judgement and a strong understanding of design, construction and commercial requirements. We develop solutions that are technically robust, practical to build and appropriate for their intended purpose.
We work closely with architects, developers, builders, certifiers and authorities to identify constraints early, reduce uncertainty and support successful project delivery.
HOW WE WORK
We begin by understanding the project requirements, objectives and constraints.
We assess the site conditions, available information, technical requirements and potential risks.
We develop practical and compliant engineering solutions tailored to the project.
We prepare designs, clear drawings, specifications and supporting technical documentation.
We provide inspections and engineering advice during construction to assist with the successful delivery of the works.
Leadership
Charbil Khoudair
Founder & Principal
Cadmus Engineering is led by Charbil Khoudair, a Chartered Civil and Structural Engineer with more than 21 years of experience across residential, commercial, industrial and infrastructure projects.
Charbil holds senior professional registrations in the civil and structural engineering disciplines across New South Wales, Queensland and Victoria. His credentials include MIEAust, CPEng, NER, APEC Engineer, IntPE(Aus), RPEQ, RPEng and registration as a Principal Design Practitioner.
His experience includes structural design, civil infrastructure, forensic engineering, defect diagnosis, remedial strategies, expert reporting and construction-phase advice. He is regularly engaged on projects involving technical complexity, constrained sites, structural risk or the need for clear and defensible engineering judgement.
Charbil personally leads every engagement, providing continuity, accountability, and experienced engineering advice throughout the project. This direct involvement is particularly valuable where outcomes carry significant financial, regulatory, or legal implications.
