Quantity Surveying that offers NO Surprises

Hi, I’m Hai Nguyen, founder of Newin Building Estimating Services, and that’s what I’ll help you do – cost and manage your building projects to ultimately ensure your project gets completed to budget and without any cost surprises.

We are a local property and construction advisory firm specialising in Quantity Surveying and Cost Management services. We work with domestic, commercial, and industrial builders, home-owners, architects, and developers at various phases: prior to construction, during construction, and post-construction.

Our why?

Over the years we’ve seen clients get caught out with poor project tracking systems, inaccurate costings, or simply “paying too much”, sadly leaving many financially strained.

We have a proven risk management system and industry track record for addressing all these.
