Pharma cold storage EPC guide: how to select qualified contractors and prepare RFQs
Temperature-controlled pharmaceutical facilities are judged on evidence, not promises. This guide sets out how to qualify an EPC contractor, what to put in the RFQ, and how to keep validation, redundancy and compliance at the centre of the procurement — so the facility passes inspection and performs for its full lifecycle.
Human Global Expert Guidance•Vendor-Neutral Procurement•Qualified International Suppliers•Commercial Confidentiality
A senior cold-chain specialist stays with your project from first brief to commissioning.
Select a pharma cold storage EPC on validated references, qualification capability, refrigerant certifications, financial bonding capacity and quality systems — not on general construction reputation alone. Prepare the RFQ as a validation-driven scope document: temperature bands, redundancy, monitoring, mapping, IQ/OQ/PQ, scope boundaries, energy basis and commercial frame. The EPC builds and guarantees; the RFQ defines what "done" means.
1. Define the facility before you contact an EPC
An EPC cannot quote accurately until the requirement is stable. The first work is buyer-side definition, not supplier negotiation.
Location, design ambient and altitude — these size condensers and plant duty
Temperature bands, volumes and tolerances: +2/+8 °C, +15/+25 °C CRT, −20 °C, ULT if required
Pallet positions, throughput, dock regime and quarantine/isolation needs
New build, retrofit or extension, and which parts of the envelope already exist
Regulatory regime: GDP, GMP, local health authority, WHO TRS if vaccines
2. Qualification criteria for a pharma cold storage EPC
General refrigeration experience is not enough. The EPC must show it has delivered validated storage before.
Validated-storage references in the same temperature band and regulatory jurisdiction
In-house or partnered commissioning and qualification (IQ/OQ/PQ) capability
Refrigerant and pressure-vessel certifications: IIAR, F-Gas, EPA, PED, ASME as relevant
Financial stability, bonding capacity and warranty/service network in the country
Quality and safety management systems that can pass a pharma owner's audit
3. Build the RFQ as a validation-driven scope
The RFQ is the contract's technical backbone. Vague language here becomes expensive interpretation later.
User Requirement Specification (URS) with acceptance criteria for each band
Design Qualification (DQ): what the design must demonstrate before build starts
Installation Qualification (IQ): evidence that equipment is installed as specified
Operational Qualification (OQ): evidence that the system operates within limits
Performance Qualification (PQ): evidence that the system performs under real load
4. State redundancy, backup and monitoring explicitly
These three items drive both CAPEX and regulatory acceptance. They should not be assumed.
N+1 refrigeration with automatic changeover, or 2N where inventory value justifies it
Standby generator and UPS autonomy for controls, monitoring and alarms
Door-open alarms, access control and excursion response procedures
Seasonal worst-case mapping in empty and loaded states
5. Fix scope boundaries and exclusions
Pharma projects fail at interfaces. The RFQ must name who owns each one.
Building shell, civil works and floor construction
Electrical supply, HV/LV, generator and UPS
Refrigeration plant, controls, monitoring and BMS
Validation documentation and regulatory submission support
Spare parts, training, warranty and post-commissioning service
6. Compare proposals on total cost and risk, not headline CAPEX
The lowest lump sum often excludes the items that make a facility compliant.
Restate every offer as delivered, installed, commissioned and qualified cost
Add allowances for named exclusions using the same unit rates
Compare annual energy consumption at the stated operating profile
Compare warranty length, response time and spares holding
Score risk: who carries performance, schedule and validation failure risk?
Who this is for and how ColdMatch works
Best for
Commercial and industrial cold chain projects, typically from USD 250,000 upward: cold rooms, refrigerated warehouses, blast freezers, processing plant refrigeration and distribution hubs.
Not a fit: domestic refrigerators, household or office air conditioning, small repair call-outs, or spare-parts-only enquiries.
Typical cold chain project types
Fruit, vegetable and horticulture cold storage with pre-cooling
Meat, poultry and fish chilling plus blast freezing
Dairy and beverage process cooling
Pharma and vaccine GDP cold chain (2–8 °C, −20 °C, −70 °C)
Refrigerated warehouses, 3PL hubs and mobile cold rooms
Cold room vs refrigerated warehouse
A cold room is a single insulated chamber, usually under ~500 m³, serving one process or storage step. A refrigerated warehouse is a multi-zone facility with racking, docks, air locks and a central refrigeration plant, sized by pallet positions and daily throughput rather than by room volume.
What affects project cost
Storage volume, pallet positions and daily throughput
Target temperature and ambient design conditions
Refrigerant choice (NH₃, CO₂, HFC) and plant redundancy
Panel thickness, doors, air locks and civil works
Backup power, solar, freight, duties and commissioning
Temperature range checklist
+12 to +16 °C — bananas, potatoes, curing
+2 to +8 °C — pharma GDP, dairy, fresh produce
0 to +4 °C — meat, fish and chilled distribution
−18 to −25 °C — frozen storage
−35 to −40 °C — blast freezing and IQF
RFQ checklist
Product, temperature and daily intake
Room dimensions or required pallet positions
Site location, ambient conditions and power supply
You define the project once — capacity, temperature and technical requirements. ColdMatch structures it into a supplier-ready RFQ, reviews it with a human specialist, then approaches suitable refrigeration manufacturers, EPC contractors and installers. Offers come back normalised so scope, price and lead time are comparable.
Using ColdMatch to scope a project, run calculators and receive supplier quotations is free for buyers. ColdMatch helps buyers compare suppliers and request quotes; it is an intermediary and does not manufacture equipment, install systems, or provide financing directly. Costs shown are indicative planning figures — only supplier quotations are binding.
Cold chain project types, temperatures and budgets
Use these reference clusters to place a project before contacting suppliers. Figures are indicative planning ranges for commercial and industrial projects from USD 250,000 upward — only supplier quotations are binding.
Project type cluster
Agriculture and horticulture cold storage
Pre-cooling plus storage for fruit, vegetables and flowers, usually +2 to +12 °C with high humidity control and fast pull-down after harvest. Sized by daily intake in tonnes, not only by room volume.
Meat, poultry and fish cold storage
Chilling at 0 to +4 °C combined with blast freezing at −35 to −40 °C and frozen holding at −18 to −25 °C. Hygienic panels, drainage and separate dirty/clean flows are part of scope.
Pharmaceutical and API cold storage
GDP-compliant 2–8 °C rooms, −20 °C and, for some active pharmaceutical ingredients and biologics, −70 °C. Requires mapping, IQ/OQ/PQ, N+1 refrigeration, backup power and alarm escalation.
Refrigerated warehouse and 3PL distribution
Multi-zone facilities sized by pallet positions, dock doors and daily throughput. Typical scope covers racking, air locks, dock levellers, a central plant and an energy strategy.
Food processing plant refrigeration
Process cooling, chillers, spiral or tunnel freezers and glycol loops integrated with production lines. Usually specified alongside ISO 22000 and HACCP food safety requirements.
Mobile and containerised cold rooms
Plug-and-play 20 ft or 40 ft refrigerated units for seasonal peaks, remote sites and temporary capacity, typically −25 to +8 °C with optional solar or generator support.

Selection criteria are descriptive of what a buyer should confirm. They do not rank or endorse any specific EPC contractor.
Step-by-step EPC qualification checklist
Run these seven steps on every candidate contractor before the RFQ goes out. Each line states what you verify and the evidence that proves it, so GDP/GMP capability is confirmed on documents rather than on claims. Tick items as you clear them and export the sheet for your procurement file.
0 of 35 checks verified
Step 1 — Legal standing and capacity to contract
0/5 verified
Confirm the entity that will sign the contract can actually carry it in your country.
Step 2 — GDP/GMP reference projects in your band
0/5 verified
General cold storage experience does not transfer to validated pharmaceutical storage.
Step 3 — Quality system that survives a pharma audit
0/5 verified
The EPC's own quality system becomes part of your evidence trail.
Step 4 — Qualification and validation capability
0/5 verified
Decide who writes, executes and approves each protocol before, not after, award.
Step 5 — Technical and regulatory competence
0/5 verified
Confirm the licences and engineering depth the plant type actually requires.
Step 6 — Delivery capacity, safety and service
0/5 verified
A qualified design fails if the team, programme or aftercare cannot support it.
Step 7 — Score, shortlist and release the RFQ
0/5 verified
Turn the verification into a defensible shortlist before technical pricing starts.
This checklist is descriptive buyer guidance. It does not rank, endorse or certify any EPC contractor, and it does not replace your own quality, legal or engineering assessment.
