How UrbanCore transformed scattered historical cost data into a standardized estimating workflow that moves from early concepts to GMP pricing

‍

‍

The data existed. The workflow could not scale with demand.

As UrbanCore grew, its developer clients needed cost information faster. Historical project data existed across Excel files, but compiling information from multiple sources could take approximately a week.

In 2023, UrbanCore adopted Zebel to centralize historical data, standardize its estimating workflow, and support estimating from early concepts through detailed pricing and GMP^{1 2}.

What once took about a week to compile can now be turned around the same day.

From scattered data to a connected estimating workflow

Before Zebel, UrbanCore’s estimating process depended on historical information stored across multiple Excel files. Estimators had to gather data from different sources, organize and interpret it, build a conceptual estimate, and then continue refining pricing as the design developed toward GMP.

With Zebel, that process became more connected. Historical project information is centralized and standardized, making relevant data easier to compare and apply. UrbanCore can develop an early conceptual estimate and continue refining it as project definition increases, moving into detailed estimating and ultimately GMP pricing.

Faster estimates are only part of the story. UrbanCore can now follow how cost expectations evolve from early historical assumptions to increasingly detailed, current pricing as the project develops.

How UrbanCore uses Zebel across preconstruction

From conceptual estimate to GMP: make variance useful

Conceptual estimates and GMP pricing answer different questions because the underlying information changes as a project develops. Comparing those stages helps UrbanCore identify where costs moved and investigate whether the change came from scope, quantities, market pricing, methodology, or evolving assumptions⁸.

Estimate variance becomes information, not simply a new number replacing the previous one.

Why historical data still needs context

Centralization makes historical information easier to access, but it does not make every historical number appropriate for every project. Estimators still need to consider pricing date, scope, project size, location, quantities, market conditions, and how closely the reference project resembles the current opportunity^{3 4}.

Once historical information is structured and supported by sufficient context, it becomes more useful for comparison and benchmarking^{8 10}.

The value is not simply having more data in one place. It is being able to retrieve the right project history quickly enough to support an informed comparison.

‍

A clearer cost story for clients

Rather than presenting each estimate as an unrelated number, UrbanCore can show how cost expectations developed as scope became clearer and current pricing became available. That continuity creates a more transparent conversation about why the estimate changed.

‍

Every project can strengthen the next estimate

Reconciliation does more than explain the current project. Updating estimates with actual costs, project changes, and lessons learned can strengthen the historical information available for future work^{3 9}.

‍

Winning with quicker cost estimates

UrbanCore adopted Zebel while growth was increasing demand on its preconstruction team. Centralizing and standardizing historical information changed the speed of conceptual estimating, from approximately a week to same-day turnaround.

The larger shift is continuity. UrbanCore can carry the estimating story from early historical assumptions through detailed pricing and GMP, reconcile what changed, and preserve that learning for future work.

Quicker estimating creates immediate capacity. A connected estimating history creates a stronger foundation for the next project.
