Deep-Dive Specification

End-to-End Procurement Pipeline Architecture

ContraVault AI orchestrates raw tender documentation into audited, portal-ready bid packages across 5 distinct execution phases and 9 procurement-standard AI modules.

The 5 Execution Phases

Complete Lifecycle Coverage from Ingestion to Archival

PHASE 01

1. Ingest & Parse

Accepts complex multi-part tender packages (PDF, scanned scanned drawings, Word, BOQ Excel, DWG files) via portal API, email, or direct upload. High-speed OCR indexes document text with page-level spatial coordinates.

Input: Raw tender package (1,000–5,000 pages)

Output: Structured, OCR-indexed page-level document repository

PHASE 02

2. Analyze & Evaluate

AI evaluates documents against corporate PQ criteria (Go/No-Go), identifies clause-level risks and internal contradictions with color-coded heatmaps, extracts technical requirements, and enables contextual search.

Input: Indexed document repository

Output: Interactive analysis dashboard, Go/No-Go scorecards, Risk heatmaps

PHASE 03

3. Clarify & Prepare

Builds structured pre-bid clarification documents, auto-populates government compliance forms and annexures (CPWD, MES, NHAI, GeM), and drafts first-pass technical proposal responses using historical content libraries.

Input: Evaluated risk points & company repository

Output: Draft pre-bid query list, completed compliance affidavits & annexures

PHASE 04

4. Collaborate & Approve

Multi-team workspace where BD, Legal, Finance, and Technical leads review, comment, edit, and approve output items under unified deadline tracking with real-time sync and escalation alerts.

Input: Draft submission package & pre-bid queries

Output: Approved, version-locked submission package with sign-off trail

PHASE 05

5. Submit & Archive

Final package export formatted for portal uploads (CPPP, GeM, State e-Procurement). Full immutable audit trail archived for compliance, post-award contract management, and future tender reference.

Input: Approved bid package

Output: Submitted PDF binders + searchable compliance archive

Enterprise Differentiator

The Output Trait Layer

Every single output generated by ContraVault AI carries 6 mandatory metadata traits, separating real procurement intelligence from generic AI text.

🎯

Confidence Score

Explicit percentage rating indicating AI certainty for every risk flag, synopsis point, or form field.

🔗

Source Attribution

Every output is hard-linked directly back to the original RFP document volume, page number, and clause index.

👤

Human Verification Status

Tracks whether a qualified engineer or legal reviewer has reviewed, edited, or signed off on the output.

🏛️

Regulatory Flag

Flags compliance against specific procurement standards (CPWD, MES, NHAI, MoRTH, GeM guidelines).

⏱️

Temporal Context

Verifies if an output is based on the latest Corrigendum/Addendum or an earlier tender revision.

👥

Stakeholder Assignment

Routes action items to specific teams (BD, Legal, Finance, Technical Lead) with deadline alerts.

Security & Compliance

Built for Indian Enterprise Security Standards

Over 70% of Indian AEC CIOs cite data security as their top adoption barrier. Here is how Tanishayan addresses it as a first-class feature.

Data Localization & Hosting

100% of tender documents, parsed data, and AI models reside strictly on MeitY-empanelled India-based servers (AWS Mumbai / Azure Central India) or customer VPC environments. Zero data leaves Indian borders.

✓ MeitY Empanelled Cloud Architecture

Encryption & Audit Logging

End-to-end AES-256 encryption at rest and TLS 1.3 in transit. Full immutable audit logging of all document accesses, edits, and sign-offs for strict corporate governance.
