Dialysis unit
Haemodialysis unit design, checked against FGI and ISO 23500
In a dialysis unit the station spacing and the water system decide whether the unit can be licensed and run safely. BMEssentia Design sizes each station against the FGI minimum, puts water treatment next to the treatment area for a short loop, and flags the water system for the specialist.
What the AI plans
- A treatment area with dialysis machines, dialysis chairs, patient monitors, a nurse station and hand-wash basins.
- A water treatment room with reverse osmosis plant and a treated water tank, next to the treatment area.
- Clean and dirty utility rooms, reception, waiting, an accessible WC, a staff room and a store.
The worked example: Haemodialysis unit, 6 stations, 170 m2
Reception, Waiting, Dialysis treatment area (6 stations), Water treatment, Dirty utility, Clean utility, Accessible WC, Staff room, Store.
The standards it checks
Each check names the guidance it rests on. Figures are the ones the named guidance states; the edition in force locally must always be confirmed.
ADA 2010 Standards for Accessible Design (US): 304.3 turning space of 1525 mm diameter; 404.2.3 door clear width at least 815 mm
FGI Guidelines (outpatient facilities, renal dialysis): each haemodialysis station has a minimum clear floor area of 80 square feet (7.4 m2); check the edition adopted locally
ISO 23500 series: preparation and quality management of fluids for haemodialysis (water treatment and distribution)
IEC 60364-7-710: electrical installations in medical locations, each room classed group 0, 1 or 2 by the electrical designer
HTM 03-01 (specialised ventilation for healthcare premises) and ASHRAE 170 (ventilation of health care facilities): air change rates and pressure relationships set by the ventilation designer
Local building, fire, accessibility and licensing regulations, confirmed by the architect and the licensing authority
BMEssentia planning practice (general engineering knowledge, not a standard)
The rules check for this example, as the engine produced it
| Status | Check |
|---|---|
| Met | Areas add up: rooms 131.1 m2 + ducts 13.94 m2 + corridor 25.84 m2 = 170.88 m2 against the stated 170 m2 (+0.5%). |
| Met | Every room opens off the corridor. |
| Met | Corridor 1.8 m wide, at least the 1525 mm wheelchair turning space; the local minimum corridor width is to be confirmed. |
| Met | All doors give at least 815 mm clear (leaf width less 100 mm for frame and stops). Door leaves: 1, 1.2 m. |
| Met | Accessible toilet: Accessible WC 2 x 2.23 m fits a 1525 mm turning circle; fixture positions to be confirmed by the architect. |
| Met | Reception is the first room at the entrance. |
| Met | Dialysis treatment area (6 stations): 6 stations, 11.6 m2 each against the 7.4 m2 minimum clear floor area per station. |
| Met | Water treatment is next to Dialysis treatment area (6 stations) (a short distribution loop). |
| For the professional | Dialysis water system (treatment, storage, loop, disinfection, testing) designed and validated by the water treatment specialist. |
| For the professional | Electrical design: medical location groups, circuits, IT supply where needed, emergency power. |
| For the professional | Ventilation: air change rates per room, pressure relationships (decontamination dirty to clean), extract from plant rooms. |
| For the professional | Fire: escape routes and travel distances, compartments, the corridor end exit shown is a proposal. |
| For the professional | Local building, accessibility and licensing rules, and the room sizes the licensing authority requires. |
7 room sizes in this example are planning figures with no source, marked to be confirmed by the professional.
How the service works
- Brief: tell us what you need. Ten minutes.
- Estimate: we scope it and send a cost estimate.
- Concept: a plan checked against the standards.
- Walkthrough: walk through it in 3D, ask for changes, approve.
- Final: drawings, equipment list and the checks, ready for your estates team.
Shielding is always set by the radiation protection adviser. Electrical, gases, ventilation, fire and licensing items go to the qualified professional. Nothing is called engineer verified unless a person really reviewed it.
Other facilities: Dental clinic, Day surgery centre, Intensive care unit (ICU), Medical spa, Imaging suite.
