Service 24 / 27 · Facility Zoning & Flow Studies
Every Route Through the Facility Is a Contamination Decision.
Many facility problems start as a line on a plan: a corridor shared by clean and used material, a gowning room with one door for entry and exit, or a waste route that crosses a production area. ALVEDA studies how people, materials, waste and hazardous substances move through the building and how they pass between classification zones, so that segregation is built into the layout rather than added through procedures later. The resulting zoning and flow diagrams become a shared basis for architecture, HVAC and the client quality team.

Technical detail
What the study resolves
Contents · 05
01 / 05
Classification zoning
Rooms are grouped by the cleanliness their activity requires, so that boundaries, airlocks and HVAC zones follow a clear logic.
- Room function and required classification
- Zone boundaries and transition points
- Separation of product types and dosage forms where required
- Unclassified support and technical areas
02 / 05
Personnel flow, gowning & degowning
Personnel are a primary contamination source; their route and gowning sequence are designed, not left to habit.
- Entry sequence from unclassified to classified areas
- Separation of clean and used garments
- Degowning route that does not cross the clean entry
- Hand-hygiene and changing-room positions
- Separate access for maintenance personnel where needed
03 / 05
Material flow
Materials follow a defined path from receiving to dispensing, production, packing and dispatch, with clear transfer points.
- Receiving, sampling and quarantine
- Dispensing and staging
- Transfer into and out of classified areas
- Finished-product packing and dispatch
04 / 05
Waste & hazardous-material flow
Waste and hazardous substances need their own routes and holding points, so they do not share paths with clean material or pass through sensitive areas.
- Waste collection, holding and removal route
- Segregation of hazardous and non-hazardous streams
- Hazardous-material receiving and storage route
- Interfaces with deactivation or treatment areas where applicable
05 / 05
Separation & classification transfer
Moving from a lower to a higher classification and back again each needs its own sequence; the strategy is defined before airlocks and pass boxes are placed.
- Production and laboratory separation
- Low-to-high transfer: cleaning, wipe-down and airlock sequence
- High-to-low transfer: exit routes and containment considerations
- Airlock and pass-box function per transfer point
Illustrative Engineering Model
ALVEDA Facility Intelligence
One compact, generic facility read nine ways — classification, pressure, air handling, the flows of people, materials and waste, utilities, laboratories and containment. Choose a layer, then a room, to see the engineering intent behind it.

01 / 09 — Z-CLAS
Classification
Cleanliness classes step up toward the point of exposure. The critical ISO 5 zones exist only inside the PEC and C-PEC, not across whole rooms.
- ISO 5 — inside PEC / C-PEC
- ISO 7 — buffer and HD rooms
- ISO 8 — ante, airlock, production
- CNC — controlled, not classified
- Unclassified
