GDP vaccine mega-warehouse (25,000 pallets) — India
Top-5 global vaccine manufacturer built a GDP + WHO PQ-compliant mega-warehouse serving domestic and UNICEF/GAVI export markets, including mRNA ULT storage.
Challenge
- Zero-excursion mandate across +2/+8, −20 and −70 °C zones in one envelope.
- 45 °C summer ambient + monsoon humidity load on envelope.
- WHO PQ, GDP, 21 CFR Part 11 and CDSCO compliance in one validation programme.
ColdMatch solution
- Triple-loop refrigeration: chilled water for +2/+8 °C, NH₃/CO₂ for −20 °C, cascade ULT for −70 °C.
- N+2 chiller redundancy, dual-utility (grid + diesel + BESS) with 72h autonomy.
- 21 CFR Part 11 monitoring (2,400 wireless loggers), calibrated mapping ×3 seasons.
- ColdMatch coordinated EPC + ULT OEM + validation partner + WHO PQ audit prep.
Project scope
- Civil: 42,000 m² envelope, 350 mm PIR, vapour barrier, sub-floor heating.
- Mechanical: 6 MW chilled water plant, 2.8 MW NH₃/CO₂, 12× ULT cascade cabinets (−70 °C).
- Electrical: 12 MVA connection, 3 MW diesel N+1, 4 MWh BESS, dual MV feed.
- Automation: BMS, EMS (ISO 50001), 21 CFR Part 11 monitoring, SCADA + ERP integration.
- Validation: URS/DQ/IQ/OQ/PQ, seasonal mapping, WHO PQ + CDSCO audit dossiers.

This project sits under the Build a Pharmaceutical Cold Chain objective. Start from the objective hub to scope capacity, permitting and budget before engaging suppliers.
Project brief → RFQ package → supplier outreach → outcome
Every ColdMatch project follows the same managed sequence. Nothing reaches a supplier before the ColdMatch project team has reviewed the brief and confirmed the project scope, budget and timeline.
1. Project brief
- Submitted via
- Pharma cold-chain RFQ — vaccine distribution
- Review
- Reviewed manually by the ColdMatch project team with GDP and ultra-low-temperature specialists
Clarified before outreach
- Volume split across +2/+8 °C, −20 °C and −70 °C storage.
- Continuity expectation during grid interruptions and monsoon conditions.
- Audit scope: national regulator plus international donor requirements.
Qualification checks
- Project value far above threshold, with programme funding confirmed.
- Named validation owner and quality lead on the buyer side.
- Distribution commitments fixed the go-live date.
2. RFQ package issued
Segmented RFQ per temperature regime, single commercial envelope
Documents in the pack
- URS per temperature zone, including −70 °C ULT redundancy strategy.
- Backup-power and hold-time requirements with defined failure scenarios.
- Mapping, monitoring and data-integrity specification.
- Serialization and inventory-system interface scope.
Mandatory supplier returns
- ULT redundancy design with failure-mode analysis.
- Guaranteed hold time per zone under total power loss.
- Validation plan with named resources and schedule.
- Spares availability and mean-time-to-repair commitments in-country.
3. Managed supplier outreach
- Approached
- 10 suppliers screened, including specialist ULT vendors
- Shortlisted
- 3 EPCs plus 2 ULT equipment vendors
- Round 1 — regulatory screen
Only suppliers with vaccine-grade references and in-country service progressed.
- Round 2 — technical tender
ULT redundancy and hold times reviewed against the URS with the quality team present.
- Round 3 — service commitment
In-country spares, response times and training negotiated into the contract.
Evaluation weighting
- Regulatory & validation capability
- 35%
- Redundancy and continuity
- 30%
- In-country service capability
- 20%
- Price (normalised scope)
- 15%
4. Commercial outcome
Multi-regime design with dedicated ULT redundancy and validated monitoring
Delivered results
- 25,000 pallet positions across +2/+8 °C, −20 °C and −70 °C.
- Validated monitoring accepted at first audit.
- Distribution commitments met on the original go-live date.

Project records are anonymised at the buyer's request and presented as planning-grade benchmarks. Costs, timelines and performance figures are indicative and are not engineering designs or quotations.
Supplier and manufacturer information is provided for research only; it is not a directory for direct contact. There is no direct buyer-to-supplier connection: every RFQ comes to the ColdMatch team, which validates it, contacts suitable suppliers on the buyer's behalf and presents organized responses through ColdMatch.
