Client Context

A property restoration firm needing precise exterior measurements to estimate materials and costs accurately without sending estimators to every site.

Understanding the Challenge

Business Needs

Manual site measurement was dangerous, time-consuming, and prone to human error. Inaccurate estimates led to material waste or profit loss.

Technical Challenges

Incorrect data mapping would lead to incorrect material orders, directly impacting project margins.

  • Webhooks needed to handle asynchronous processing of 3D models.

  • Data parsing required handling complex JSON structures for roof and siding measurements.

  • Integration had to associate measurements accurately with CRM job records

Solution Architecture

Webhook Listener

A secure listener endpoint was built to receive real-time notifications from Hover when property 3D models were fully processed.

Auto-Estimation

Upon receipt of measurement data, the system automatically populated line items in the estimation software, applying pre-calculated waste factors.

Risk-first design

Designed against failure modes

Polling the API for status updates. The solution used webhooks to ensure real-time responsiveness and reduce unnecessary API traffic.

Implementation
Approach

Event-driven architecture to handle asynchronous 3D processing.

01

Established secure webhook listeners to receive Hover event payloads.

02

Mapped complex JSON measurement data to CRM estimation line items.

03

Automated the material estimation and waste calculation logic.

04

Rolled out to estimators with fallback manual overrides.

The Strategic Tradeoff

Automation must be robust enough to handle data variability without human intervention.

Outcomes and
Impact

Safety

Eliminated dangerous roof climbs for measurement.

Accuracy

Reduced material waste by 15% through precise measurement data.

Speed

Reduced estimation time from days to minutes.

The Bottom Line

Precision is
Profit

In construction, accuracy protects margins. We turned physical risk into digital precision.
