Glen Sim is a highly experienced Building Consultant, Licensed Builder, Construction Consultant, and Expert Witness with more than 35 years of practical experience within the Australian building and construction industry. As the Founder and Director of Awesim Building Consultants, Glen has established a strong reputation throughout Sydney and regional New South Wales for providing independent, evidence-based building consultancy services and expert reporting for complex building and construction disputes.

Beginning his career as an apprentice carpenter with TAFE NSW in 1990, Glen completed his apprenticeship in 1993 before progressing into senior construction and management roles across residential, commercial, and remedial building sectors. His extensive industry background provides him with genuine hands-on construction knowledge — something that distinguishes him from many consultants who have limited site-based experience.

Glen became a Licensed Builder in Victoria in 2004 before returning to New South Wales in 2011, where he continues to operate under NSW Builder Licence No. 232673C. Over the course of his career, he has worked across all stages of the construction process, including carpentry, supervision, project management, contract administration, construction scheduling, defect rectification, quality control, and dispute resolution.

Today, Glen is widely recognised for his expertise in:

Expert Witness Reports
Scott Schedules
NCAT Building Disputes
Construction Defect Investigations
Building Defect Reports
Quantum Meruit Assessments
Construction Programming & Delay Analysis
Client-Side Project Management
Contract & Scope of Works Assessments

Glen regularly assists homeowners, builders, developers, solicitors, strata managers, insurers, and commercial clients by providing technically detailed and independent reporting for litigation and dispute resolution matters. His reports are prepared with a strong understanding of the requirements of the NSW Civil and Administrative Tribunal (NCAT), court procedures, the Expert Witness Code of Conduct, the National Construction Code (NCC), Australian Standards, and accepted building industry practices.
Over 15+ years experience providing litigation support with expert witness reports and Scott schedules.
What clients value most about Glen is his practical approach, integrity, attention to detail, and ability to clearly explain complex construction issues in a manner that is easy to understand. His combination of trade-based experience, construction management knowledge, and investigative expertise allows him to identify issues that are often overlooked by less experienced consultants.

Over the years, Glen has developed a reputation for producing thorough, methodical, and evidence-supported reports that clients and legal representatives can rely upon during negotiations, mediations, tribunal proceedings, and litigation matters. His commitment to accuracy, professionalism, and impartiality has made Awesim Building Consultants a trusted name in the building consultancy industry across NSW.

Glen is also known for his strong commitment to client service, ensuring every matter is approached with professionalism, transparency, and genuine care for achieving practical outcomes. His experience across both metropolitan Sydney and regional New South Wales provides him with a broad understanding of differing construction methods, site conditions, workmanship standards, and project delivery challenges throughout the state.

Outside of the construction industry, Glen values family life and regional Australia. He has been happily married to internationally recognised author Audra Starkey since March 2025. Together, they share a passion for supporting rural communities and building trusted professional relationships grounded in honesty and respect.

With more than three decades of industry experience, Glen Sim continues to provide trusted building consultancy and expert witness services backed by real construction knowledge, independent assessment, and a commitment to helping clients navigate complex building matters with confidence.
