It’s been a busy week here at Retro Construction! We’ve been crunching numbers with our professional construction estimation software, putting together detailed project plans for clients and banks, and making sure everything’s on track for our next builds. On top of that, we’ve updated our processes and refreshed our Paid Estimates article to help clients better understand the many benefits of opting for a paid estimate instead of a free one.

Worried about budget blowouts? Retro Construction uses advanced estimation software and NZIQS protocols to provide accurate, transparent building quotes in Auckland. No hidden fees, just facts.
The biggest fear for any homeowner planning a renovation or commercial build is the dreaded “budget blowout.” We have all heard the stories: a quote that looks great on paper, only to double halfway through the project due to “unforeseen extras.”
At Retro Construction, we believe financial surprises have no place in building.
That is why we do not rely on “guesstimates” or back-of-the-envelope math. Instead, we utilize advanced Estimation Software combined with over 30 years of industry experience to provide professional, detailed quotations.
1. The Science Behind the Quote
Many builders give you a single figure that hides the details. We provide transparency. Our in-house construction estimator uses specialist software to calculate exactly what is required for your project, from the number of timber framing meters to the exact volume of concrete.
- Accuracy: We measure twice—digitally and on-site—so we cut once.
- Real-Time Pricing: Our software is updated with current material costs, protecting you from outdated pricing data.
2. Understanding the “Hidden” Costs (Preliminaries)
A common source of budget anxiety is “Preliminaries” (or P&G)—the costs involved in setting up and running your site safely. Less transparent builders might hide these, leading to shocks later. We are upfront about the fact that a building site operates like a “temporary outdoor factory”.
- What this covers: Scaffolding, waste management, health & safety compliance, and site protection.
- The Reality: On most compliant New Zealand sites, these essential operating costs account for 11–15% of the total contract value. By using our estimation tools, we factor these in from day one, ensuring your budget is realistic and robust.
3. Alignment with Industry Standards (NZIQS)
We don’t just make up the numbers. Our estimation process aligns with the protocols of the New Zealand Institute of Quantity Surveyors (NZIQS). This signals professionalism and ensures that our quotes follow an industry-wide ethical standard. When you receive a proposal from Retro Construction, you are receiving a document based on data, not guesswork.
4. Commercial Rigor for Residential Builds
Because we also manage complex Commercial Work, we bring a higher level of financial discipline to your residential renovation. We track costs with the same rigor whether we are fitting out a warehouse or extending your family home. This “Traditional Experience” combined with “Modern Style” technology ensures that your project stays on track financially, just as it does structurally.
