Adnoc Gas Megaproject Cost Estimator with Google ADK & Gemini 2.5 Flash

Contractors announced $8.2bn in awards for Adnoc Gas projects. Build a multimodal estimation agent using Google ADK and Gemini 2.5 Flash to ingest engineering diagrams, bill-of-quantities (BOQ) spreadsheets, and site reports. Produce cost variance projections with a confidence threshold within 3% of baseline engineering estimates.

What you are building

Utilize Google ADK with Gemini 2.5 Flash to process engineering blueprints and tabular BOQs for gas megaproject financial control.

How work is evaluated

Evaluation

Evaluates accuracy of cost estimation and scope mismatch detection from BOQ files and diagrams.

Datasets

Public datasets, plus the private datasets you have access to.

How submissions are scored

Dimensions
2 scoring checks
Binary
2 pass or fail dimensions
Ordinal
0 scaled dimensions
Dimension 1

valid_calculation

Checks sum calculation accuracy across BOQ lines

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.

Dimension 2

estimation_accuracy

Accuracy relative to benchmark gold cost estimation • target: 0.97 • range: 0-1

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.

Learning goals

  • Configure Google ADK with Gemini 2.5 Flash for multimodal data processing.

  • Parse engineering schematics (P&ID) alongside pricing spreadsheets.

  • Detect cost anomalies and scope gaps across multi-billion-dollar project contracts.

  • Generate structured budget summary reports conforming to corporate governance rules.
