It allows us to process large volumes of information quickly and consistently – it doesn’t replace experience. The balance comes from using the technology to inform decisions while relying on professional judgement to understand context, risk, and nuance. The combination of data and experience delivers real value.

Q Construction Limited is an award-winning main contractor and delivery partner in commercial construction and temperature-controlled facilities, operating across New Zealand’s North and South Islands. The firm coordinates design teams, specialist subcontractors, and supply chains to translate client requirements into fully realized built assets, prioritizing collaboration in construction and frictionless projects, with a strong focus on health and safety, community, and environment.
Q Construction’s story is about how data, experience, and judgment come together to support better conversations and better outcomes both internally and with their clients. The firm values the ability to provide clients with reliable, confident cost guidance very early in the planning process – particularly before full design information is available. Like many organizations, Q Construction was working with a large and growing volume of live and historical project data but capturing and reusing that information in a consistent way was challenging.
Providing meaningful guidance on early-stage cost advice, often before designs were fully developed and without relying on assumption, required a reliable cost database. Real-time budget clarity was the core challenge – to combine systematic data captured from live projects with historical information analysis and align it in a consistent format to be benchmarked and interrogated. While they had plenty of data, it was difficult to compare and reuse as it was spread across different projects in different formats. To make sense of it, Q Construction turned to RIB CostX to transform detailed construction knowledge into practical insights for the feasibility stage.
Q Construction’s decision to implement RIB CostX has enabled them to put in place a repeatable cost planning approach. By using consistent coding structures and templates, they can now quickly analyze, compare, and reuse the information rather than start from scratch each time. They are now able to test options in real time, adjusting scope elements to immediately see the cost impact of those adjustments. Balancing speed with accuracy, CostX helped organize their project data to make smart early-stage decisions confidently.
Q Construction understands the pressure on both clients and consultants to make decisions quickly with limited design detail and tight timelines, without early cost guidance. Design teams risk spending valuable time and fees exploring ideas or revising concepts that aren’t practical instead of refining solutions that are deliverable within the client’s budget. Without solid cost information, it’s hard to discern if a design is truly feasible. Changes downstream can be disruptive, costly, and stressful.
The challenge was to move away from the uncertainty of thinking what it might cost to knowing what similar projects cost in reality – it was about being able to show the client what’s driving cost, building trust through transparency.
To meet this challenge, they needed a deep understanding of historical costs. Until that point, they had relied on high level assessments from past and live projects for budget indications. They didn’t lack data, but it was disparate, spread across different projects and formats and time periods. They couldn’t compare and reuse the data– it needed to be organized to facilitate fast, reliable decision-making. It was mostly in trade format and needed to be converted live into concept-level elemental budgets without losing critical assumptions to be applied against similar projects alongside careful, critical analysis. That’s how they came to use CostX: to find the right balance that would ensure they could influence decisions quicky enough with advice grounded in defensible evidence.
Once you make a start, structuring data from a few completed projects in a consistent way makes a big difference in that over time that information becomes incredibly powerful.

Agnew’s advice to other contractors and consultants still using spreadsheets or one-off estimates who want to develop a reliable database for early-stage cost advice, is to start small and focus on consistency. With CostX as the organizational engine, Q Construction followed a systematic process to make sense of real project data:
- They built a benchmark library that gets stronger with every job, using CostX to back-cost live and completed projects.
- They converted detailed trade-based costs into element costs and work packages that aligned directly with early concept designs.
- Consistent coding and templates were applied for fast comparison and reuse.
- Scope options were tested in real time to see cost impact immediately.
- Combining technology with professional judgement, they interpret the data correctly.
With reliable cost insights, they can test cost drivers and guide discussions around scope and priorities – actively adjusting scenarios, adding or removing elements, they can immediately see the effect on the budget.
This is not about software replacing expertise – Q Construction are using RIB CostX combined with their expertise and experience to understand the nuances of each project. This approach has really changed how they support clients at the front-end of projects, while clients and consultants value the early clarity. It gives them confidence that their projects are being tested properly from the start.
We’re refining our templates, improving how we capture information from live projects, and bringing that into conversations much earlier with clients and design teams.
Lisa Agnew, Senior Estimator
The firm’s cost-planning methodology is consistent and repeatable yet grounded in real project evidence – not just theoretical rates. It’s a confidence boost for Q Construction’s clients when cost drivers are clearly explained, budgets are validated, and they’re shown exactly where the numbers come from. Agnew notes that consultants like coming to them as early as possible because they know exactly what to expect and find the input supportive of their work as it helps them deliver a better service to their clients. And stronger, more collaborative relationships are being developed with consultants through this earlier, better-informed engagement.
As the dataset gets stronger with every project they complete, it makes the system more robust over time. It changes the nature of client conversations as the cost database is built on evidence, particularly with repeat clients. It becomes easier for the client to understand the trade-offs, so they can have far more productive discussions about priorities in future.
Q Construction’s early cost planning and budget advice approach is now about continuing to build on what they’ve started with RIB CostX:
- Every project they deliver feeds real data back into their cost database, so their cost advice keeps getting stronger, smarter, and more reliable.
- They are building a repeatable, evidence-based way of working that supports better conversations from day one.
- It strengthens their ability to spot value engineering opportunities early in the process.
- They’ve identified a huge opportunity in helping clients make confident decisions earlier before designs are locked in and changes become expensive.
- Their goal is to engage with consultants and clients proactively to build relationships and trust based on improving the quality of decisions made right at the start of projects.
What stands out to Agnew is how this CostX approach mirrors their mindset shift away from starting every project from a blank page, creating a one-off estimate or implementing a tool in isolation. While they still absolutely rely on the core skills and technical grounding that quantity surveyors and cost planners are trained on, they have simply changed the first step in the process.
Now they look at what they already know in test assumptions against the real project data first. Rather than replacing expertise, the data is strengthening it, giving Q Construction a benchmark to challenge, validate, and refine thinking.
I just wish we’d started capturing the data earlier and structuring it this way. It’s never too late to begin building a better foundation!
