Construction Cost Tracker
User Guide

The Buildara Construction Cost Tracker is a professional project cost management tool designed for New Zealand residential builders, developers, project managers, and quantity surveyors.

Unlike a traditional spreadsheet, the tracker allows you to compare estimated costs with actual spending, monitor project progress, identify budget risks early, and keep every construction cost in one organised location.

The tracker is suitable for projects of any size, from single-house builds to multi-lot residential developments.

Click New Project to begin a new construction project.

Entering a new project will clear any existing project data, allowing you to start with a clean workspace. You will then be prompted to complete the Project Setup before adding any cost items.

Open Project Setup and enter the basic project information.

Typical fields include:

• Project Name
• Site Address
• Total Budget
• Currency
• Construction Start Date
• Expected Completion Date

This information is used throughout the dashboard for reporting and budget monitoring.

Record each construction cost as an individual line item.

For every item, enter:

• Cost Category
• Subcategory
• Supplier or Contractor
• Estimated Cost
• Actual Cost (when available)
• Status
• Quote or Due Date
• Notes

Examples of categories include:

• Site Works
• Foundation
• Framing
• Roofing
• Windows & Doors
• Kitchen
• Bathrooms
• Electrical
• Plumbing
• HVAC
• Flooring
• Painting
• Landscaping
• Professional Fees
• Contingency

Each item can be edited or deleted at any time.

Each cost item can be assigned one of three progress statuses:

• Pending — Quote has not yet been confirmed.
• In Progress — Work has commenced or payments are ongoing.
• Complete — Work has finished and the final cost has been recorded.

Status indicators provide a quick overview of project progress.

The tracker continuously compares:

• Estimated Cost
• Actual Cost
• Cost Variance
• Variance Percentage

When actual costs exceed the original estimate, the variance is highlighted automatically.

Items with significant cost overruns are visually flagged to help identify issues before they impact the overall project budget.

The dashboard provides an instant summary of your project's financial performance.

Typical indicators include:

• Total Estimated Cost
• Total Actual Cost
• Total Cost Variance
• Number of Cost Items
• Budget Remaining
• Overall Budget Performance

These values update automatically whenever project data changes.

To simplify large projects, costs can be grouped by category.

For example:

• Kitchen
• Flooring
• Electrical
• Landscaping
• Professional Fees

Each category displays:

• Total estimated cost
• Total actual cost
• Category variance
• Number of items

Categories can be expanded or collapsed for easier navigation, especially on large projects.

The integrated Risk Panel continuously analyses project data and automatically generates alerts when potential issues are detected.

Examples include:

• Total estimated costs exceed the project budget.
• Actual costs exceed estimates by more than 10%.
• Actual costs have been entered without an original estimate.
• Construction has started while items remain in a Pending status.

These alerts help project teams identify financial risks early and take corrective action before costs escalate.

Project data can be exported for reporting and record keeping.

Available options include:

• Export to CSV
• Print-friendly project summary

CSV files can be opened in Microsoft Excel, Google Sheets, or other spreadsheet applications for further analysis.

The tracker is fully responsive and automatically adapts to smaller screens.

On mobile devices:

• Cost items are displayed as easy-to-read cards.
• Group totals remain visible.
• Estimated, Actual, and Variance values are clearly presented.
• Overall project totals are summarised at the bottom of the screen.

This allows project managers to update costs directly from the construction site.

The tracker calculates:

• A positive variance indicates the project has exceeded the original estimate.
• A negative variance indicates savings compared with the original budget.

Colour indicators help interpret the results:

• Record estimated costs before work begins.
• Update actual costs as invoices are received.
• Review risk alerts weekly.
• Monitor high-variance items closely.
• Keep supplier information up to date.
• Add notes explaining major budget changes.
• Export regular reports for project meetings and client updates.

• The tracker is intended as a project cost management tool and does not replace formal accounting software.
• Actual costs should be verified against supplier invoices and payment records.
• Regular updates provide the most accurate budget monitoring.
• Construction projects should always maintain an appropriate contingency allowance for unforeseen expenses.
