About Ninety3
Ninety3 is a team of Registered Quantity Surveyors focused on improving the quality, clarity, and financial management of construction projects - from early concept budgets through to completion.
The business was founded to address a common issue within the construction industry:
Projects are often under-valued initially and have poor cost management throughout the build. This frequently results in projects with compromised quality, time delays, and avoidable cost overruns. Ninety3 exists to bridge that gap.
By combining accurate early cost planning with ongoing cost monitoring, Ninety3 provides clients and contractors with clear financial insight at every stage of the build. This approach supports informed decision-making, reduces risk, and helps prevent unnecessary time and cost blowouts - before they occur, not after.

VISION
Our Industry Vision
We believe construction works best when pricing is fair, realistic, and properly understood by everyone involved. Ninety3 exists to bring balance back into how costs are planned and managed, where contractors are priced fairly for the work they do, and clients pay what the project genuinely requires - no more and no less.
The cheapest price is rarely the best outcome. Fair pricing leads to better decisions, fewer disputes, and stronger working relationships across a project. Our role is to create that fairness through clear scope, disciplined cost control, and independent, professional advice. When costs are handled properly from the outset, projects run smoother, trust improves, and everyone involved ends up better off.
