Our Quantity Surveying Services across Melbourne

Construction Cost Management and Contract Administration

We serve as the initial point of contact between the design and construction teams and our clients, which may include homeowners, builders, or developers. Our role encompasses conducting a construction audit, from the pre-verification of costs before project commencement to the ongoing tracking and monitoring of expenses throughout the construction process.


Construction Cost Project Claim Assessments and Performance

We will evaluate and provide recommendations for both progress and variation claims. Additionally, we will diligently monitor various project budget components, including the costs of completed work, work in progress, and, when required, the costs associated with defective work. Our overarching objective is to guarantee that the construction expenses remain in alignment with the approved budget.

Newin has a proven track record of working with numerous leading banks and a deep understanding of their specific requirements in these areas.

Construction Cost Plans and Estimations

We specialize in cost estimation for a broad spectrum of projects, spanning residential, commercial, and industrial developments. Our process involves meticulously calculating the expenses associated with materials and labor, all tailored to the specifics of your project design and specifications.

Our services cover the full project lifecycle, from high-level feasibility cost analyses to comprehensive design cost assessments, both pre and post-tender. Our overarching goal with these cost plans is to provide an independent and thorough evaluation of your project’s budget, pinpoint potential risks, and identify avenues for cost savings.
