Technical Specification Builder

Generate a formal, RFQ-grade technical specification for your cold-chain project in minutes. Buyers attach this document to any tender so that supplier quotes are directly comparable — no hidden scope gaps, no apples-to-oranges pricing. Independent and supplier-neutral.

- Vapor barriers continuous; floor heating cable grids under frozen rooms with monitoring.
- Cold-store doors: motorized bi-parting or hi-speed roll-up, heated frames, safety edge, opening cycle rating ≥ 200,000.
- Dock equipment: insulated levellers, inflatable shelters, air-curtains at every reefer bay.

- Refrigeration controls: open-protocol (Modbus TCP / BACnet IP) — no proprietary lock-in.
- BMS shall log temperature at ≤ 5-min intervals for a minimum of 24 months with tamper-proof audit trail.
- Remote alarm to on-call engineer via SMS + email; escalation matrix documented.
- Trending, KPI dashboard and export to CSV / API for buyer's ERP / WMS.

- **Primary supply:** Utility grid with diesel/gas backup genset (N+1)
- Backup power shall carry 100% of refrigeration load, 100% of controls, 50% of lighting, and dock equipment.
- Auto-transfer time ≤ 10 s; fuel or battery autonomy ≥ 12 h at full load.
- Power quality: THDi ≤ 5%; power factor ≥ 0.95 at PCC.
- All motors ≥ IE3 (IEC 60034-30-1); VFDs on all compressors and evaporator fans.

- **FAT (Factory Acceptance Test):** buyer or nominated inspector to witness; pass/fail criteria pre-agreed.
- **SAT (Site Acceptance Test):** performance run over ≥ 72 h at design load; deviations logged and re-tested.
- **Pull-down test:** empty and loaded pull-down curves recorded.
- **Temperature mapping (empty + loaded):** minimum 12 data-loggers per room, 48 h each phase.
- Independent commissioning agent recommended and priced as an option in the bid.

Supplier shall deliver, prior to final payment, hard copy + editable soft copy of:
- Heat-load calculation, refrigerant charge calculation, pipe-sizing report
- P&ID, single-line electrical, control philosophy, cause-and-effect matrix
- As-built drawings (architectural, structural, MEP, refrigeration)
- Equipment datasheets, serial numbers, refrigerant certificates
- O&M manuals in Nigeria local language + English
- Training records (minimum 3 buyer staff, 3 days on-site)
- Spare parts list with 24-month critical spares priced separately

- **Warranty period:** 2 year(s) from SAT sign-off, parts and labour, response ≤ 24 h.
- **Critical spares stocked:** 2 year(s) of consumables and wear items priced at bid stage.
- **Service level agreement (SLA):** MTBF, MTTR and uptime targets shall be quoted for optional 5-year extended service.
- **End-of-life:** supplier shall quote refrigerant recovery and equipment take-back option (F-Gas / Kigali compliant).

Bids shall be evaluated on the following weighted matrix — buyer will not award on lowest capex alone:
| Criterion | Weight |
