1 · Total Land Area Estimate
The absolute minimum viable land area for a single-line IV (BFS) bottle plant, operated on a logical linear flow with a single-story building, is:
How it's derived
Building gross ≈ 1,908 m². At a 40% site-coverage cap, the building needs ≥4,750 m² of land. Netting a realistic truck court, generator pad, ETP and fire-access ring brings the floor to ~4,500 m², with ~5,000 m² advised.
Single-story logic
Vertical stacking of cleanrooms is avoided — it compounds HVAC load and contamination risk. One story keeps the footprint honest and the flow simple, which is the compact choice for this capacity.
Scaling note
This figure anchors one BFS line (~10–20M 500 ml bottles/yr). Output was not stated by the client; give us the target annual capacity and we re-scale the land, building and utility matrices 1:1.
2 · Zonal Layout Breakdown
Preliminary area allocation for the essential departments. Building gross ≈ 1,908 m²; ~20% is circulation/ancillary.
| Department | Area (m²) | Area (ft²) | Key contents |
|---|---|---|---|
| Water for Injection (WFI) + PW gen & loop | 120 | 1,290 | Distiller / RO-EDI, storage tanks, distribution loop |
| BFS Cleanroom (Gr C + A/RABS, gowning, airlocks) | 300 | 3,230 | Blow-Fill-Seal machine + clean envelope |
| Sterilization (autoclaves + depyro tunnel) | 120 | 1,290 | Terminal sterilization of filled units |
| Inspection & Packaging | 220 | 2,370 | Visual inspection, labeling, carton, case pack |
| Warehousing (RM / comp / WIP / FG / quarantine) | 450 | 4,840 | High-bay racking, 7–9 m clear |
| QC Lab & Sampling | 100 | 1,080 | Microbiology + physico-chemical |
| Utilities / Plant (HVAC, compressors, chiller, elec) | 180 | 1,940 | On mezzanine over the core |
| Ancillary (change/locker/WC, QA/admin, circulation) | 410 | 4,410 | Incl. ~20% internal circulation |
| Gross building | 1,908 | 20,450 | Single-story, linear flow |

3 · Site Plan
Proposed 70 × 70 m envelope. The building sits centrally with a truck court on the dispatch side and external services (generator, ETP, water tank farm) pushed to the perimeter so they don't consume the building footprint.

4 · Spatial-Efficiency Recommendations
How to keep the footprint at the absolute minimum while preserving a logical production flow:
- Linear single-story flow: Receive → RM store → WFI → BFS cleanroom → Sterilization → Packaging → FG store → Dispatch. No backtracking, no cross-contamination corridors.
- Mezzanine the utilities (HVAC, compressor, chiller, electrical) over the clean core — pulls ~180 m² off the ground footprint.
- High-bay racking in the warehouse (7–9 m clear) instead of spreading storage horizontally — the single biggest area saver.
- RABS over full isolator for BFS to shrink airlock/gowning volume while holding Grade A at the fill point.
- Co-locate WFI next to the clean core to shorten the distribution loop and pipe runs.
- Push ETP, generator and bulk tank farm external (perimeter) so they don't eat the building.
- Prefab / modular cleanroom shell to speed delivery and tighten tolerances.

6 · Design Basis & Assumptions
- One Blow-Fill-Seal (BFS) line, ~10–20M 500 ml bottles/yr (output TBC by client).
- Terminal sterilization; WHO / EU GMP Annex 1, Grades A / B / C / D.
- Greenfield, flat site in Angola; single-story building; 40% site-coverage assumption.
- WFI via multi-effect distillation + RO/EDI pre-treatment; purified-water loop included.
- High-bay racking (7–9 m clear) for warehousing; utilities on mezzanine.
- External services (generator, ETP, water tank farm) sited on perimeter.
- Status: Proposal / Preliminary design basis. Figures are engineering estimates for feasibility and land-banking, not for construction. Capacities, prices and approvals are TBC pending client data.
