The Challenge
A construction company with builders and quantity surveyors across South Africa was facing significant inefficiencies in their estimation process for painting, plastering, and other room-based work:
Time-Consuming Manual Measurements
Quantity surveyors had to physically visit each property, measure every room with tape measures, and manually calculate surface areas. A single house could take 2–3 hours to measure and estimate.
Prone to Human Error
Manual measurements led to frequent errors in calculations, resulting in inaccurate quotes that either lost money on jobs or lost bids to competitors. Remeasurements were common.
Slow Quote Turnaround
Clients often waited days to receive quotes because of scheduling site visits and processing measurements. In a competitive market, this delay cost them business to faster competitors.
Limited Capacity
With only so many hours in a day for site visits, the team could only process a limited number of quote requests. This bottleneck prevented business growth.
The Solution
Deltum developed an AI room measurement and estimation tool that uses computer vision to revolutionize the quoting process:
1. Computer Vision-Based Measurement
Take a simple photo of any room with a smartphone. AI analyzes the image to identify walls, ceilings, and features, automatically calculates dimensions and surface areas, and accounts for windows, doors, and other exclusions.
2. Instant Quote Generation
Automated calculation system with pre-configured pricing for painting, plastering, and other services. Provides automatic material quantity calculations, labor cost estimation, and professional PDF quote generation.
3. Mobile-First Design
Built for field workers who need to work on-site. Works on any smartphone or tablet with offline capability for sites with poor connectivity and a simple interface requiring minimal training.
4. Quality Control & Validation
Built-in accuracy checks with confidence scores for each measurement, option for manual adjustment if needed, historical data comparison for sanity checks, and a full audit trail of all measurements and quotes.
Implementation Process
Discovery & Requirements (Week 1: Days 1–2)
Analyzed current estimation workflow, interviewed quantity surveyors and builders, identified key measurement scenarios, and defined accuracy requirements.
AI Model Development & Testing (Week 1: Days 3–5)
Configured computer vision models for room analysis, integrated pricing logic, built mobile interface, and conducted initial accuracy testing with sample room photos.
Field Testing & Refinement (Week 2: Days 1–3)
Deployed to pilot group of quantity surveyors for real-world testing. Collected feedback, refined measurement algorithms, and optimized for different lighting conditions.
Full Rollout & Training (Week 2: Days 4–5)
Rolled out to entire team with hands-on training sessions. Created quick-reference guides and video tutorials. Team was using it confidently within hours.
The Results
The impact was immediate and transformative across all key metrics:
80% Time Savings
What used to take 2–3 hours per property now takes 20–30 minutes. Estimates that took days are now done in minutes during the site visit.
95%+ Accuracy
AI measurements consistently match or exceed manual measurement accuracy. Dramatic reduction in estimation errors and costly remeasurements.
3x More Quotes Daily
Team can now process 3x more quote requests per day without adding staff. Converted the estimation bottleneck into a competitive advantage.
Instant Client Delight
Clients receive quotes while still on-site or within hours instead of days. Dramatically improved customer experience and conversion rates.
Additional Benefits
"This tool has transformed our business. We can now quote on-site and give clients instant pricing. Our conversion rate has skyrocketed."
