The Process

How the AI Audit Works

Five precise steps from raw contractor quote to your negotiation arsenal.

01

Upload Your BOQ

Submit your contractor's Bill of Quantities as a PDF, Excel file, or a clear photo of a physical quote. All formats accepted.

02

AI Extraction

The AI extracts every line item, unit, quantity, and rate — normalising them into standard construction phases: Earthwork, Foundation, Superstructure, and Finishing.

03

Cross-Reference Database

Each line item is checked against configured completeness rules and indicative benchmark ranges.

04

Detect Anomalies

Missing items, vague specifications ("standard tiles", "as required"), unbounded rates, and undefined material grades are automatically red-flagged.

05

Engineer-Reviewed Report

A senior civil or structural engineer reviews the AI's output and adds professional judgment before your negotiation playbook is delivered.

FAQs

Frequently Asked Questions

Why do contractors omit items from BOQs?

Some contractors deliberately exclude items like basement filling, sump, waterproofing, or compound wall to make their initial quote look cheaper. When these items arise during construction, they charge premium "extra rates" with no prior agreement — sometimes at 2–3× market rate, since you're already mid-build with no alternative.

Does the AI know current Chennai material rates?

Yes. The engine is calibrated against Buildogram's material procurement database reflecting current Chennai wholesale rates for steel, cement, sand, fly-ash brick, and finishing materials — updated July 2026.

What BOQ formats do you accept?

PDF, Excel (.xlsx, .csv), and clear JPG/PNG photos of physical contractor quotes. Our AI can read tabular data from all common contractor quote formats used across Chennai.

Is the AI decision final?

No. Every report is reviewed by a senior civil or structural engineer before delivery. The AI handles extraction and pattern-matching at scale; humans make the final professional judgment and sign off on all findings.

How long does it take?

Preliminary AI analysis runs in under 2 minutes. The full engineer-reviewed report with your negotiation playbook is delivered within 24 working hours.
