Case Study: Sparrow Construction achieves standardized, scalable cloud-based estimating with ProEst

How ProEst standardizes the estimating process with built-in flexibility

Sparrow Construction, a family‑owned Wellington, New Zealand builder with 25 employees and a 55‑year history that averages about 50 estimates and NZD 10M in annual revenue, faced a challenge: owner Mike Sparrow was running all estimating from customized spreadsheets that lacked scalability, standardization and cloud integration. Looking for an online platform to support a varied project portfolio and a cloud‑first business model, Sparrow selected ProEst Cloud in 2019.

ProEst deployed its cloud‑based estimating platform, delivering standardized templates, a structured database and spreadsheet‑style flexibility in a collaborative environment. The ProEst solution let Sparrow Construction scale staff easily, produce polished proposals, enforce consistent productivity norms, and reduce spreadsheet errors—supporting continued estimate volume and driving improvements in quality, productivity and profitability.
