Day surgery centre
Day surgery centre design over two floors, planned with AI
A day surgery centre puts consulting, imaging, theatres, recovery and sterile services in one building. BMEssentia Design stacks them over floors, places the equipment and checks each floor against the guidance it names.
What the AI plans
- Operating theatres with the operating table, surgical light, anaesthesia workstation, ceiling pendants, patient monitor and electrosurgical unit, each with a scrub.
- A recovery area with patient trolleys, monitors and a nurse station.
- Sterile services (CSSD) with a large washer-disinfector and steam steriliser, a dirty utility and a sterile store.
- Consulting rooms, an X-ray room marked as shielded, an ultrasound room, a pharmacy, staff changing and a plant room.
The worked example: Day surgery centre, 2 floors, 900 m2
Reception, Waiting (20 seats), 4 x Consulting room, X-ray room, Ultrasound room, 2 x Accessible WC, Pharmacy, Staff room, Plant room, 2 x Operating theatre, 2 x Scrub, Recovery (6 bays), Sterile services (CSSD), Dirty utility, Sterile store, 2 x Staff change.
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
HTM 01-05 (England, decontamination in primary care dental practices): a one-way flow from dirty to clean, with separate dirty and clean zones, and a dedicated hand-wash basin; a separate decontamination room is best practice
Radiation shielding is specified by the radiation protection adviser or qualified expert (for example IRR17 in the UK, NCRP Report 147 in the US, or the national regulator)
IEC 60364-7-710: electrical installations in medical locations, each room classed group 0, 1 or 2 by the electrical designer
NFPA 99 (Health Care Facilities Code) and HTM 02-01 (medical gas pipeline systems): dental air and vacuum plant, intakes and discharges designed by the gas engineer
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: floor 0 448.47 m2 + floor 1 448.52 m2 = 896.99 m2 against the stated 900 m2 (-0.33%). |
| 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, 1.4, 1.6 m. |
| Met | Accessible toilet: Accessible WC 1 2 x 3.67 m, Accessible WC 2 2 x 3.67 m fits a 1525 mm turning circle; fixture positions to be confirmed by the architect. |
| Met | Reception is the first room at the entrance. |
| Partly met | Ultrasound room: no hand-wash basin in the equipment list (one is drawn in the layout). |
| Met | Plant room is away from treatment and waiting, at the end of the plan with its own outside door for servicing. |
| For the professional | X-ray room: walls marked as shielded on the plan; the shielding (material and thickness, doors, viewing) is set by the radiation protection adviser. |
| For the professional | Electrical design: medical location groups, circuits, IT supply where needed, emergency power. |
| For the professional | Compressed air and suction: plant sizing, pipework, intake and exhaust positions. |
| 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. |
| 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, 1.4, 1.6 m. |
| Met | Sterile services (CSSD): separate dirty and clean doors and zones, one-way run from the dirty end (sinks, washer) to the clean end (steriliser, packing). |
| Met | Sterile services (CSSD) is away from the public rooms. |
| Met | Sterile services (CSSD) has a dedicated hand-wash basin. |
| For the professional | One stair and lift core on every floor, in the same place. Patients on beds or trolleys use the upper floors, so the lift shown is a bed lift; its car size and the number of lifts are set by the lift supplier and the traffic analysis. |
| Partly met | Only one stair is drawn. Most codes need at least two escape routes from upper floors: the fire engineer sets the number and position of escape stairs. |
24 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, Dialysis unit, Intensive care unit (ICU), Medical spa, Imaging suite.
