Our Quantity Surveying Services across Melbourne

Construction Cost Management and Contract Administration

We can act as the first point of contact between the design and construction team and the client (Home Owners, Builders, or Developers). We can facilitate a construction audit related to the pre-verification of costs before a project commences to tracking and monitoring costs during construction.


Construction Cost Project Claim Assessments and Performance

We’ll assess and recommend progress claims and variation claims. We’ll monitor project budgets,  the costs of works complete to date, cost of works in progress and/or cost of defective works (if necessary), ultimately ensuring the cost of construction is within the approved budget.

With our construction project management services, we offer on-site assessments of the builders progress claims.

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 Melbourne and Sydney-based 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.

The result- greater confidence that your project will be delivered on time and within budget.

With offices across Australia, as well as Auckland, New Zealand, and powered by 18 year’s + experience in the construction industry, over 7000 reports behind us, we’d love to share how we can help with your building project whether it’s a renovation, new home build, commercial or even a high-rise residential project.
