About Us
Cornerstone Estimating Pty Ltd is a contract management and cost consultancy company based in Melbourne, Australia, servicing commercial subcontractors in Melbourne to help them with commercial management, contract review, change management, and margin protection services in their projects. Our lead consultant and business owner, Kevin, has built up a reputation and experience in the Construction Contracting space over the last 15 years that is here to help you. Our goal is to meet and exceed the expectations of every client, managing risk early, making clear decisions during delivery, and finishing projects while keeping profit.
Many subcontractors work hard, deliver quality outcomes, and still struggle financially. The issue is rarely effort or capability. It’s usually a lack of structure around the commercial side of construction. We exist to bring clarity, discipline, and practical support to that part of the business so subcontractors can operate with confidence instead of reacting to problems after the damage is done. Our work is hands-on and project-focused. We stay involved before and during construction, when decisions still matter and leverage still exists.
While providing tailored solutions to Construction Businesses, every project is handled with the highest level of precision and compliance. We are dedicated to delivering professional, cost-effective, and valuable services, whether it’s managing complex tenders, navigating the Security of Payment Act (SOPA), or resolving disputes. We pride ourselves on our commitment to quality, integrity, and exceptional results.
